How to Downgrade PSP & Upgrade to a Custom Firmware (2)

How to Downgrade PSP & Upgrade to a Custom Firmware (2) muog psp2On Sunday, we posted the first part How To Downgrade your PSP & Upgrade to a Custom Firmware Read More of this guide, about how to downgrade your PSP and then upgrade to a custom firmware.


For those of you who’ve just tuned in; a custom firmware is one that is written by hackers (or crackers, depending on your point of view), which gives you all the possibilities of the official firmware, but also enables the use of homebrew.

Update: MakeUseOf released a Free PSP Downgrading/Upgrading Guide in PDF. Download here.

Homebrew are applications developed not by Sony, but by the community. The different types of homebrew applications range from text editors to ISO loaders. Due to the latter one, which enables piracy, Sony is strongly against homebrew and does its very best to contain it.

There’s a constant battle between the homebrew community and Sony. Each fix is quickly followed by another exploit.

Last week we posted about various ways to downgrade your firmware. Today we’ll guide you through a method that works for nearly all PSP’s, disregarding the current firmware. It even allows you to unbrick PSP’s (people call a PSP bricked when it stops working due to software abnormalities).


So why didn’t we skip the previous part? Simple, the Pandora Battery method requires either the use of a PSP with custom firmware, or a spare battery pack. So if you haven’t got one of those, but you’ve got firmware 3.50 or below, use part one How To Downgrade your PSP & Upgrade to a Custom Firmware Read More .

All PSPs can be cracked, disregarding current firmware. You’ll need to use a Pandora battery for all models except those with a TA-88v3 motherboard (some versions of the PSP-2004, the PSP 3000 and up). Here you’ll need to use a temporary crack. You can view your PSP model at the bottom of the device.

To check if you’ve got a TA-88v3 motherboard, look for a white sticker on your box and look at the printed letter. This will indicate your firmware, as well as your production line and thus your motherboard.

    • – (No Letter) = 3.60


    • – A = 3.71


    • – B = UNKNOWN


    • – C = 3.72


    • – D = UNKNOWN


    • – E = 3.80


    • – F = 3.90


    – G = 3.95 / 4.01 (TA-88v2 / TA-88v3)

A PSP with 4.01 firmware (and up) installed most certainly has a TA-88v3 motherboard as well.


– non-TA-88v3 : Follow this article, or Download the Updated PDF Guide How To Downgrade your PSP & Upgrade to a Custom Firmware Read More .
– TA-88v3 and >PSP3000 : follow this tutorial


Using these methods is 100% legal (although Sony obviously doesn’t like it), but it CAN brick your PSP (every model except the PSP-3000 can be unbricked using a working Pandora Battery, though). It may also void the warranty of your PSP system as you would be working with delicate parts like the PSP’s flash memory. So if you screw up, Make Use Of won’t be held legally liable. If this sounds like too much risk to you, please don’t go any further.

The Pandora Battery

The homebrew community was always looking for different ways to get in. Sadly, Sony kept closing these entrances one by one, and there are only so many doors in a house.

At a certain moment, there was an unexpected turn – a new way in that worked for all available PSP’s (at that moment). They had ran out of doors, but they had found a sledgehammer! They reprogrammed the PSP battery (naming it Pandora Battery), which enabled them to overwrite the PSP’s flash memory.

So what is it?

This method uses a hacked battery (Pandora Battery), which then runs specific software to hack your PSP from the ‘Magic Memory Stick’.

Batteries that are compatible:

– Sony “standard” Li-ion 1800 mAh
– Sony PSP-280 2200mAh
– Atomic Battery Pack 3.6V 1800mAh
– Datel, PSP Battery 3600 mAh (X2)
– Datel, PSP Battery 1800 Max Power

Batteries that are not compatible:

– 2600 mAh Mega Battery Pack
– Sony PSP-280 2200mAh (Fake)
– Sony PSP Bloc-Battery pack 3.6v 1800 mAh
– Battery 3600mAh, unknown brand, (China made model NK-RH008) (Fake)
– Battery Pack, unknown brand, (lithium) 3.6v 3600 mAH (Fake)
– Intec 2200 mAh

Memory sticks that are compatible:

All memory sticks with the “Pro Duo” tag should work. Official ones will work better though.

There are a number of different ways to apprehend the Pandora Battery set, we’ll be discussing them below.

Option 1: I have another custom firmware PSP

This is the best (and cheapest) way of doing so. If you don’t happen to have two PSP’s lying around, try to borrow a friend’s.

What you need:

  • Pandora Installer for 3.xx Revision 4b
  • Version 1.50 eboot
  • Version 3.40 eboot
  • Version 3.80 eboot
  • A Fat PSP with custom firmware
  • A Pro Duo memory stick (at least 256MB, but under 8GB)

Making your Magic Memory Stick

Start out by putting the Pandora Installer on your CFW PSP. Do so by moving the pan3xx folder from the downloaded archive to E:PSPGAME (where E: is your PSP).

Go out of USB mode, navigate to Game -> Memory Stickâ„¢ and click on the Pandora Installer to start the application.

How to Downgrade PSP & Upgrade to a Custom Firmware (2) paninst

In the application, go to ‘MemStick and MS-IPL options‘ and select ‘Repartition‘.

When your PSP has restarted, connect through USB and recreate the E:PSPGAME hierarchy. Again, drop the pan3xx folder in here.

This time you must also put the versions 1.50, 3.40 and 3.80 eboot files in the PSPs root (main folder) and name them respectively 150.PBP, 340.PBP and 380.PBP

Go out of USB mode again, navigate to Game -> Memory Stickâ„¢ and click on the Pandora Installer to restart the application.

This time, select Install a DDCv4 MagicStick (for Fat + Slim), this is the version that works best with both Fat and Slim PSPs, and wait for it to finish.

Finally, choose to install the ELF-Menu and NAND-Tool. Some of you might not find this necessary, but some slim PSP’s give trouble without it.

Next, press battery options to produce your Pandora Battery. You can also make a back-up of your battery’s serial number here.  This can be used while restoring your battery later on. As an alternative, you can also use an automatically generated serial number. This should work fine, but make a dump if you want to play safe.

Congratulations! You are now the proud owner of a Pandora Battery and a Magic Memory Stick. Read this part if you don’t know how to use it.

Option 2: I have a spare battery

There is another way though, if you can’t get your hands on a CFW PSP. You can still hardmod your battery, but this involves cutting it open and quite more risk than the above method, so proceed with caution and completely at your own risk. Also, don’t go buying an extra battery for this method, the option below is cheaper and guaranteed to work.

As I have not tried this myself, I will send you to someone who has. Follow this picture-guided tutorial step by step, and you should be fine, but don’t come crying to us if you mess up.

Once you are done, you can follow these steps to make a Magic Memory Stick without the use of a CFW PSP.

Option 3: I have none of the above

How to Downgrade PSP & Upgrade to a Custom Firmware (2) 41ystd1a7ql aa280

Of course it could also happen that you don’t have any friends with a (custom firmware) PSP, nor a spare battery. Instead of buying a brand new battery to cut open, you can always spend less money for more certainty.

Available on eBay and Amazon are ‘Tool’ batteries, from Datel. These are batteries that are already modified! (i.e. you’ll only need a Magic Memory Stick).

If you have one in your possession, use the below steps to make yourself a Magic Memory Stick

Making a MMS without a CFW PSP

If you don’t have a CFW PSP you can use to mod your batteries, you probably won’t have a PSP to make you a Magic Memory Stick either.

Luckily, it’s also possible to do this directly through your PC, using Rain’s Simple MMS Maker (available for Windows Xp & Vista). Download it here.

You’re also going to need a 1.50 and 3.80 eboot file, which can be downloaded respectively here and here.

How to Downgrade PSP & Upgrade to a Custom Firmware (2) 23522 rainmmsfj6

To use the program, just select DCv4 from the dropdown list and locate the 3.80 eboot file. Also check the Formatting checkbox and choose to add the 1.50 Kernel addon if you have a fat PSP.

Now, to make your MMS, just press the big button at the lower right.

Find out how to use your Pandora Battery Below.

Using your Pandora Battery

Make sure you have your Magic Memory Stick inserted and put in your battery, a black and white menu should pop-up. Then, go to recover and choose to install the 3.80 Custom Firmware (M33).

Just wait for it to finish (grab some coffee, this can take a while), and you’re done. You are now running a 3.80 M33 Custom Firmware!

Upgrade to the latest Custom Firmware

As you might have noticed, you’re on CFW 3.80 M33 now; that isn’t very high up the ladder, considering CFW 5.00 M33-3 is already available (or even higher, by the time you read this). Follow the steps below to upgrade to the latest custom firmware.

Files you need:

  • The latest M33 Firmware version (5.00-3 at the time of writing) [No Longer Available]
  • The parallel official fimware (5.00 in this case) [No Longer Available]

a) File placement

Extract the downloaded archives.

Move the unRARred UPDATE folder to X:PSPGAMEUPDATE (with X: being your PSP). Also add the parallel official firmware to that folder, renamed in the same manner as in 2.a How To Downgrade your PSP & Upgrade to a Custom Firmware Read More

How to Downgrade PSP & Upgrade to a Custom Firmware (2) folder1

b) Updating

Go to Game -> Memory Stickâ„¢ and open the installation file. After verifying the eboot, it’ll ask you for confirmation. Press X to continue.

Follow the on-screen instructions to update. The update will take five minutes or less.

Congratulations, you are now on the latest M33 custom firmware!

    Hello, so to make this opening short my Pandora battery isn't working at all. I made it myself, pin-5 is cut, and the battery was charged before I cut it and worked perfectly no holding it in place or anything. It is an official Sony PSP 1800mAh battery pack.

    From what I've read the battery could not be making a connection (even though it worked before) so I still tried and pressed it in and tried to manually turn the PSP on. That still does nothing. The connection is made because when I plug my PSP into charge and then put the battery in the light goes from Green to Orange (So my PSP isn't bricked either because it boots). When I go into the battery information with the battery plugged in it says this...

    Charge Level 0%
    Hours Left -
    Power Source External
    Battery Status Charging

    Also from what I've read, even if I didn't make the MMS correctly when I plug in the battery it should still turn on (Green light) and at least be a dead screen. Neither of which happen.

    I used PSPgrader 8 to make the MMS and I used the L trigger as the Tigger button and yet when I hold it in and then plug in the battery still nothing.

    PSP info:
    VERSION: 6.61
    MODEL: 1001 (Fat)

    lately ive been seeing online that there are ways to make a pandora battery without openning it or having cfw or using a tool battery. it has to do with some software that disables something in the battery instead of cutting it. is this true? it seems logical to me but i am no psp expert. im not sure but i think pan3xx is one of them. you you could respond asap that would be very helpful.

    So, I messed up and accidentally updated my PSP to OFW v6. I'm thinking, since I don't have the money to buy the TOOL battery, the battery converter appliance, or the Pandora battery, that I can go ahead and try to trade it in at GameStop for one with a lower firmware. What I want to know is...

    If the PSP that I get (I will be making sure that the firmware is what I need before I buy it) is running OFW v5 or less, can I update to the newest CFW WITHOUT having to buy the battery or make a MMS? It's my understanding that the newest firmware is v5.50. Is that correct?

I asked that becuase I watched some webs make MMS and pandora battery useing pandora program,that is mean after made MMS in PC and we put pandora program in PSP. Can We make my battery to be pandora battery using pandora battery?.I so sorry if I inconvenience you.thanks

      You can find all this in the article.

      It is possible to make a MMS on your PC, if you've got a cardreader, you don't even need a PSP.

      It is not possible to make a Pandora battery with just your PC and an standard PSP, even if you have a working MMS.

      To get yourself a pandora battery you'll need to
      a) find someone with a cracked PSP who can help you
      b) buy a pandora battery or TOOL battery online - they're actually quite cheap
      c) hardmod your battery (this involves cutting open, and permanently ruining your battery -- not advised)

      It's always better to use a Phat battery, as Slim batteries sometimes err. It's worth the try though.

    Well I just completed downgrading a psp-1001 w/ Official 5.1 update down to 3.8 and am now looking into updating the homebrew. This is a great guide! One thing, after you've made your MMS(Magic Memory Stick) and modding your pandora battery... at the point where you insert the battery: MAKE SURE you hold down the LEFT TRIGGER while inserting the battery and release the trigger when the Memory Stick light begins to flash, or else it will just boot up like normal (at least it did with my version). The guide didn't mention this or at least I didn't see it.

    Also, actually hardmodding the battery was pretty sketchy, all the videos I watched to see how to do it were all showing PRE-opened batteries and it wasn't easy the first time around. You really have to go slow and saw away at the seam all the way around the battery casing. Paying special attention to the top 3 prongs on the battery because I almost broke mine off trying to get the battery case apart. Luckily it all worked :)

    Thanks to all that contribute to this and all you crazy programming folks. Good luck to all.

    This guid is incredible, i've used nearly every possible method for modding my friend's as well as my multiple psp's and this guid has all of THE BEST methods. On top of that, dependable download links for the m33cfw and ofw 1.50 are also available! you people rock! i bow in respect to your magnificence -_-
    for everybody else just be careful about updating! always grab your new cfw updates from trusted sites (sony ninjas and saltry Dark Alex enemies have placed bricker (fake) cfw everywhere)

    I bought Pandora battery with LED and 8 gb memory stick from pandora sales.

    Battery has been fully charged and I hold the L1 button when I put in the Pandora Battery.

    I then click LED button 3 times on the battery (to change it to Pandora mode) and the lights on the battery starts flashing (to indicate it is on Pandora mode). However at this point I should see a green light on corner of PSP light up and something on the screen. However, in my case, the PSP remains shut/switched off with no lights except that on the Pandora battery flashing.

    I have PSP slim v3.90 and having checked extensively on the net, I have confirmed I should be able to install CFW on my PSP.

    I also remade the MMS using Rains UltraLiteMMSMaker and re-tried but experienced the same problem.

    Could you please advice on what the problem could be.

    Thanks in advance for your help.

(it's a psp 2004 version 4.01, letter G. How long do i wait before this can be hacked? will you post it here as soon as you find a way to hack it? i visit this site everyday hoping to see the news that it can now be hacked... any suggestions?

    This is a very good guide, I've been trying to convert my sons PSP to CFW for several weeks.

    Going thru the guide it says download OFW 1.50 but then there is no mention of what to do with the 1.50 file... I've gotta think this is an omission by error.

    Please advise.

    Thanks, your guide gives me hope.

    July 25, 2009 at 3:44 pm

    !!!!! - READ BEFORE COMMENT - !!!!!

    q: I've got a 'something' PSP, can I hack it?
    a: All PSPs can be cracked, disregarding current firmware, except the PSP-3000 and some PSPs with the newer TA-88v3 motherboards (like some PSP-2004 's.
    To check if you've got a TA-88v3 motherboard, look for a white sticker on your box and check the printed letter. This will indicate your firmware, as well as your production line and thus your motherboard.
    (No Letter) = 3.60
    A = 3.71
    C = 3.72
    E = 3.80
    F = 3.90
    G = 3.95 / 4.01 (TA-88v2 / TA-88v3) BUT
    A PSP with the 4.01 firmware and up installed is most likely a TA-88v3 motherboard as well. The above tutorial won't work.

    q: I turn my PSP on and get a blank screen, even though the battery indicator is green!
    a: This means your battery is modded, but there's something wrong with your Magic Memory Stick. Go over the steps again, or check the updated PDF guide (link at the top of the article). Alternatively, you can search for other MMS techniques with Google.

      After a little research I could semi-crack my psp using Chicken R2. However if I switch it off it will go back to its original shape. There is no risk getting it bircked and you don't lose your warranty because you can return it to its original firmware. I recommend it. And it also works for PSP 3000. Thanks for your answer Simon. Your full crack method is good but I had to use a semi-crack because it doesn't work on mine. I hope this is good news to some of you guys.

      • Majestique
        July 26, 2009 at 9:47 am

        Now to add the description. First of all you should know that all you have to do after hacking it, is not turn it off but use it in stand by mode. Don't take off its battery or its memory card. You can easily re-hack it when it turns to its original shape. The hack is for 5.03 firmware. First you use Chicken R2, then you use hen v2 which installs the program on it. Chicken R2 is a folder of some pictures which allow entrance to the ram of the PSP when you try to display them. Later your PSP restarts with the new custom firmware. You go to the games folder and install hen v2. After you install it you press left or right button only once to display the firmware. Then you press O to restart it. And you're done. You can play iso and cso games on it. There are videos on youtube that describe the installing. Good Luck.

    Hi. I didn't have time to look at all comments in order to find out if there is an answer to my question so i appologise for that.
    I own a PSP slim 2004 with a system software version of 5.03. I took it to a place and they said that it can only be semi-cracked meaning that if i shut it down or take off the battery, it will return to its original form. I agreed and they cracked it for me. I played for a few days and i kept leaving it on Stand By until one day the crack went back by itself. I'm sure I didn't switch it off or removed its battery. I am in another country now and there is nobody that knows how to do that again.
    Can you please help me crack it or semi-crack it myself?
    Thank you.

    June 13, 2009 at 8:37 am

    OK guys i found a way to know ur PSP is not a TA-88v3 Motherboard... first get ur PSP box and on any of the sides there is a white sticker on the white sticker you will see a letter... for example the sticker of mine says

    CEL PSP-2004 Is

    now as u see above u will see A letter alone mine is E...
    Locate it and check the Letters below...

    (No Letter) = 3.60
    A = 3.71
    C = 3.72
    E = 3.80
    F = 3.90
    G = 3.95 / 4.01 (TA-88v2 / TA-88v3) BUT
    A PSP with G and the 4.01 firmware is most likely a TA-88v3 motherboard

    and can u guess where i'am from

      1. If not specifically mentioned (CFW or M33), you can assume it's the original firmware.

      2. No, the tool battery is for Pandora use ONLY - that's why it's so cheap.

      3. There's always a slight chance. Not a big one, though.

      If you succeed in downgrading, yes. Then you can reverse the battery back to normal. If you fail to do so, you'll have to find another way.

      You can also buy a TOOL battery (see article) which is specifically designed to serve as a Pandora battery. That way you won't have to risk anything with your normal battery.

    Can a cfw psp connect to the internet? and can it do basic tasks like web browsing, online multiplayer and ofcourse the PSN. But i heard rumors that if sony finds out that you are on cfw they will block from your PSN it true?

      May 21, 2009 at 2:53 pm

      Easy on the caps. Both might work, although there are problems with some of the PSP-2004 motherboards. Best way to find out is to try it out, just make sure you're able reverse your battery if it fails.

      • Mike
        May 23, 2009 at 2:53 am

        wat do u mean "reverse your battery if it fails"
        or should i borrow ma friends 4.0v battery ::::::::::::

          May 23, 2009 at 8:07 am

          You need to make your battery into a 'pandora battery' to attempt downgrading. Afterwards, you need to find a way to reverse it to a normal battery, otherwise you won't be able to boot your PSP with it.

          To reverse your battery, you either need use your own (modded) PSP, or that of a friend.

    • Simon Slangen
      May 21, 2009 at 1:09 pm

      The application can only be used on an already hacked PSP. You either need to find one of those, or use an alternative method.

    May 21, 2009 at 11:44 am

    Ok i think option 3 is the best but do i neeed a pandora batt by the way are the Firmwares are they CFW or OFW

    • Simon Slangen
      May 21, 2009 at 1:07 pm

      OFW = Official FirmWare (the one from Sony)
      CFW = Custom FirmWare (the hacked one)

      If the meaning can't be derived from the context, you can assume we're talking about OFW.

    I've got fw 5.03 and have bought the sony psp gps receiver.
    they're 2 problems, no software, and downloading doesn't seem to effect anything.
    It doesn't matter what i do, it will never seem too work.
    I can't even see a differents in connecing it yes or no.
    Do you know how to activate the gps receiver on my psp?
    Can you please help me?
    I'm out of options and buying a new one with software is out of the list.
    Here in holland its pretty expensive.

    One thing people might want to know is that it I think it only works on Windows XP. I tried it on Vista, everything went fine, but the Pandora does not activate in the PSP. When I did it on my XP computer, it worked in one try.

    i downloaded Rain’s UltraLite MMS Maker and used it to make the magic memory stick, and used it with the pandora battery.

    have you got the battery tool device or you still waiting on it?

      Hi michael,

      i've tryed that method but it doesn't function. I've got the same tool battery, i bought it 2 months ago. And i'm asking it because if it has a black filled circle ( [Broken Link Removed] ) it is the psp that cannot be hacked (aka TA088v3), if not ( is hackable (aka TA088v1/2). And i bought the PSP on December 2008, and mine has got a black filled circle on it.

          hacked my 2004 slim PSP and my brother in law's one.
          the actual flashing of the PSP took less than 2 minutes (i didnt even have a chance to make myself coffee lol)

          i would like to thank Simon for this easy to follow tutorial and to everyone that made this possible.

    Hey there. Just to tell you, I got as far as the Black and White Screen (thanks to the commenter that posted the comment to "install MS-IPL command". I think it was Mark Ashton) Anyway, I finally got to the Black and White Screen. When it came to installing the 3.80 M33, It gives me an error "Loading Update Modules.... Failed -> Error 80010002 Loading module nand_update" i think it went something like that. Please i need help on what to do

    Hi there. I was trying option 1. I followed your instructions to make the memory stick which was
    - download the 4 files
    - put the pan3xx folder into E:\PSP\GAME
    - disable USB mode then run the program from the PSP game->memory stick
    - and select the "repartition..." from the MemStick and MS-IPL options

    Everything went well until the restart. After i restarted the psp (when it asked me to do so), the memory stick was renamed to "PANDORA"(instead of it usually being "Memory Stick") and it was completely empty. i still created the E:\PSP\GAME and again put the pan3xx folder in it and i also put the 3 PBP files in the root (they were in the same area as the PSP folder). I tried to run it now, but then i went to Game->Memory Stick, it said that "There are no games" where the pandora installer was suppose to be. PLEASE HELP ME!!!

    By the way. I am using my friend's psp (cfw 5.00 M33-3) and a SanDisk Memory Stick Pro Duo 2.0GB (Magic Gate).

    Firstly your patience for helping others is very commendable Simon & all other contributors refreshin to see\read.

    Havin had 2 modded psps stolen, I have had them replaced with PSP-2003 PB Black dot and G on the barcode one running Version 4.01 and the other is 4.05 (i think son has that one).

    tricky to get hold of phat cfw (2weeks til lend friends); so considering the Tool Battery from amazon and 512mb card to complete the cfw install.. just wanted to get a thumbs up that these methods would work on this model and firmware..

    seems to have changed so much since lasted d\graded; days of using GTA:LCS was sooo much easier ;-)

    Many Thanks, Stuart

    Hi, i have a PSP 2001 official CFW 4.01. i have the magic stick and battery made a long time ago, but they both work fine, because i use it on my fat psp and the menu shows up to upgrade to 3.80 m-33. i put it in my slim, and the same thing shows up. ok, its going all well so far. but when i change the settings so that the menu for downgrading to 1.5 shows up, it only works on my psp phat, and not on my slim. my problem is that when i put the memory card and battery into the slim, the menu for downgrading does not want to show up, but the menu for upgrading to 3.80 CFW shows up. can i just put "upgrade" to 3.80 CFW even though i start off with a 4.01? or do i have to find another way to downgrade it to a 1.5 first? thanks

    • Simon Slangen
      March 2, 2009 at 3:29 pm

      Yes you can, and once you're on 3.80 CFW, you can upgrade to 5.xx CFW.

        March 2, 2009 at 6:07 pm

        • Diego
          March 2, 2009 at 6:54 pm

          also, did you skip the step where you have to install ms0:/MSIPL.BIN to the memory stick? because i tried your method (which is different from the one i use currently) and when i put the memory stick and the battery inside the phat psp (havin problems with slim) nothin comes up.

          after i do all of this i decided, wait, dont you have to DOWNGRADE before you upgrade to CFW? so in the options menu in Pandora Installer program(the one i downloaded from that guys video(his and yours are different)), there is an option to put the "1.50 downgrade" option in the menu when you put the pandoras battery in the psp. i try this on the phat, it works, but i try it on the slim, and it doesnt work. can i just go from 4.01 official firmware to 5.xx CUSTOM firmware?

    I folloed the steps to make the battery using PSP 1001 CFW 4.01M33 and it said " sucessful in making Pandora battery. I put this in a PSP 5.02 OFW and I just get a black screen. I put the battery in my CFW fat PSP and I get a black screen. Any thoughts??

    LOL..can i ask? am i know an official member of the psp hackers society? (if theres any)^^

    my psp now seems to work fine, i hope.
    i have downgraded from an OFW 5.03 into the CFW 3.80 M33
    thnx for all the tutorial, the comments and suggestions

    nect thing to be done, update it into 5.0+ M33 CFW..weepee!!

    BTW, to help, befor, my problem seems to be with the way i reformat my MS, dont reformat your MS using your psp formatting system, somewhere in the system settings. the MS should be clean. it should only contain the 3 eboot files 150, 340 and 380 boot files and the folder directory PSP/GAME/pan3xx (definitely with the files containing in the pan3xx folder)

      I got a phat psp running OFW 5.02 and bought a pandora battery using a SanDisk 1GB with magic gate. Tried using a bunch of MMS Apps and still no luck. All I get is a blank screen with the green light. Any help would be greatly appreciated.

        I tried using Rain’s UltraLite MMS Maker and gives me an error of “The IPL failed to inject, general write error during IPL Injection, This could be due to the memory stick, Without IPL pandora will not boot, would you like to continue anyways?” Does this mean I need a new memory stick?

      You can try, though the softmod applications tend to refuse altering your battery. Best is if you use a Phat PSP.

    i bought a psp slim 2004 with OFW 4.01 with that motherboard that is not hackable yet.
    what if i upgraded that with ofw 5.0?
    can i downgrade that with a pandora battery

    Simon, the one who tried hacking my psp2006 said that the board of my psp is same as the ones of psp3000. he said that the only option left for us is to wait until the time comes that it becomes hackable. is it true? i hope he’s wrong. i can’t wait to play with my psp. if he’s right, can you tell me when will the crack of that board be perfected?

    • Simon Slangen
      February 17, 2009 at 2:34 pm

      I haven't heard anything specific about the PSP-2006 having an unhackable motherboard, but the possibility exists that some of them have.

      To answer your other question:

      There is a method to downgrade the PSP-3000, and other PSPs with that motherboard.

      Only thing is, you can’t use it. Sony took Datel to court after the latter anounced their ‘little blue tool’ - a service battery that’s claimed to work even for the non-crackable PSP-3000s.

    • Simon Slangen
      February 12, 2009 at 3:20 pm

      Hmmm... Are you sure your battery is modded correctly? (Does the PSP turn itself on when you insert it?)

      If so - since you don't have one of the problem models - I'd just try several different ways of making your MMS. There are tons available if you do a Google search.

  155. mac
    February 12, 2009 at 7:06 am

    simon, it really did not work. we already used the "rain" thing but it still did not work. is there any other way? or can we burn UMDs with a mini dvd and just put a case on it? will it work? i hope you could make some suggestions. thanks simon.

    • Simon Slangen
      February 12, 2009 at 3:22 pm

      If it didn't turn itself on, the problem lies with the battery, try making it again - optionally using another way.

      You can't burn UMDs yourself, I'm afraid :-)

    February 12, 2009 at 4:17 am

    hi simon, unfortunately the rain software wont work.huhu after inserting the pandora bats plus the Mems, it didn’t turn itself on. so i think this psp has a ta-088 v3 board.. :( uhmm another question, can we create our own UMD's even if the psp runs at OFW? will it work?

      This means that your Pandora Battery is working like it should, but your Magic Memory Stick doesn't.

      There are tons of different ways to make one, certainly one should work for you. Personally, I'd advise you to try making it with the 'new' Rain’s UltraLite MMS Maker

    i made a battery and an mms(green lite, black screen)
    the serial number is a AB02*******-PSP2001, i read that u can't hack them (in reguards to s/n AB02)but on this site you say that the only unhackable psp is the 3000, coincidently... if this is true, i suck because i purchased a phat psp because i read that they are hackable no questions?

    • Simon Slangen
      February 11, 2009 at 9:03 am

      I'm sorry, the information above is slightly outdated.

      The unhackable PSPs are the PSP-3000 and the PSPs with a TA88v3 motherboard. This includes the PSP-2001 and PSP-2004 with OFW 4.01/4.05 pre-installed.

      Fear not however, for these motherboards are on the verge of being cracked.

    Hi Simon,

    Firstly thanks for the great guide. I'm a newbie and my new psp slim with OFW 3.80 so i follow your guide part 2 option 1.
    Question 1 - My battery is the original Sony Li-ion 1200 mAh (model S110). Your compatible battery listed: Sony “standard” Li-ion 1800 mAh. So can i proceed to make this batt pandora?

    Question 2 - I used a CFW PSP to creat the magic memory stick successfully. the pandora installer gave a msg that TA085 mainboard cannot make pandora batt. Will i damage my batt if i try?

    Thank you

    • Simon Slangen
      February 10, 2009 at 10:31 am

      I wouldn't try it with your 085 if I were you, you might risk ruining your battery.
      You need to use another, Phat PSP (not a slim).

      You also won't be able to use your Slim battery, simply because it won't fit in a Phat PSP.

      The cracking of the PSP-3000 is indeed progressing. They're able to run simple pieces of code now.

    There seems to be a theme of users with 2001, 2003 models experiencing black screens and green battery lights using even the latest MMS makers and variations. Is there something stopping us from updating to CFW?

    February 3, 2009 at 10:48 pm

    I'm having a small problem trying to hack a psp 2001 w/ an 85vcc or 85vc3 (cant make out the last character). This was recently bought. So i've made the mms and the pandora battery from the files that you posted but all i get is a black screen with the green led light on. Not only that but this has happened with other people's psps and the result is the same. is there a way to get past this problem? (i've followed several other guides also with pandora installer and also the rain mms maker, still no luck though >.<)

    Hi Simon,

    Been reading your discussion with others about this unbrick thing. You seem pretty genius in this matter in which I really hope you can answer my dilemma.

    I'been searching all over for this few days about PSP 2000 Slim. Which if I'm not mistaken by now, it come with with 2 kind of motherboard, the hackable and not hackable. Thanks to you and others for sharing this interesting topic.

    At the moment, I'm trying to downgrade my PSP that came with OFW 4.0. What I understand, it stil can be done only if I don't have the motherboard they use for PSP 3000 (if my understanding is not mistaken). My big question is, HOW do i know/check what kond of motherboard my PSP used??

    Really appreciated your answer in this.

    • Simon Slangen
      February 3, 2009 at 6:39 am

      Look at your PSP model number (like said in the article).

      So basically, you can use any PSP, except a:
      - PSP-2004 with a TA88v3 motherboard
      - PSP-3000 or above

      If your PSP-2004 came with either FW 4.01 or FW 4.05, it’s almost definite that you have a TA88v3 motherboard.

      • ady

        February 4, 2009 at 1:39 am

        Sorry if I'm sound a bit dumb. I read somewhere in other forum, that PSP 2000 have two kind of motherboard. The one that bought after November 2008, have a big chance been installed with the TA88v3 motherboard. But there also a chance it's still usea the old one.

        I did checked the label under the UMD door, it only write PSP 2000 Slim a the end.

        Can you tell me how to check the motherboard label. Thanks.

    Hi Simon,

    I have:

    Datel Tool (Red)
    PSP Slim 2003-PB now on 5.03 OF
    2Gb Magic Gate Lexmark

    Tried all types of MMS and tricks to get my PSP into Custom. But running into problems. I can successfully make the MMS, but when I try to boot it, I only ever see a black screen and green power light, the MMS is never accessed (orange light). Tried using the boot keys (L trigger or whatever is set in the app i.e. DC v8, Rains MMS)... Really having no luck.

    Is it possible to CFW this PSP, can you guide me please? I am wondering if this model is a no go, although it hasn't been clear from forums if it is.

    Hope to hear from you

      i cant understand what youre trying to say when you sed:

    I have the same issue as beloy , I just got me a new psp , Old one finaly died after much service *SIGH* but the jerk at EB games wouldnt let me check out the box(for numbers). so I got home and it is a psp 2001 pb with OFW 4.01 on it. The box year print on th back reads 2007*( year ) so is it hackable? I've look everywhere and got mixed reviews and no solid facts. I got a pandora battery and mms coming in from pandora battery buys. SO i hope im not wasting my time with my order. Need your help Simon.
    Much thanks for the great advise.

    I haven't done your guide for now because right now i don't have a MS (4G below) but looking in your guides it really seems that it is working. I will downgrade my 5.02OFW to CFS as soon as i have my MS. Thanks to your guide I really appreciate your efforts.

  193. Max
    January 18, 2009 at 1:25 pm

    I have a simple question that 5.00 M33-4 custom firmware is already out so if i update it with the parallel official firmware you have given above in this guide will their be any problems? (Since you had linked CFW 5.00 M33-3 with the OFW 5)

    • Simon Slangen
      January 19, 2009 at 10:07 am

      Nope, the 'parallel firmware' is still FW 5.00, so go ahead.

      • Max
        January 22, 2009 at 8:05 am

        One other question dude and I know its a noob question but i could'nt find the answer anywhere.When we install a firmware upgrade on a psp where does it store all that data (of the firmware and all its new features) in the hard disk or the memory stick. The reason i am asking this is because if I change my memory stick and put in a new one , I am worried i will go back to vanilla psp slim (that is OFW 3.6).

        • GTO
          January 22, 2009 at 8:11 am

          It's installed onto the "internal harddisk" called FLASH. So you can freely change your MMC with another one, and you can also (after installing CFW) format that memory that you used for installing that particular CFW (notice that you can, but you don't have to do it if you have another MMC).

          Greets, GTO

    first, this is the best guide that i have found after weeks of looking. good work!! when i try to pandorize my battery it wont work. its a psp-2001 with 5.02 OFW. i have cut through the wire in 3 places and even cut the little peg off. it just wont do the pandora thing when it supposed to do the black & white screen!!!!! but it still works like normal. is my battery screwed or what? or am i just doing it wrong?

    • Simon Slangen
      January 16, 2009 at 2:01 pm

      The pandorization of your battery surely failed if you can still boot your PSP like normal.

      So you either did something wrong or have an incompatible battery.
      If you're sure you did everything right, you can help others by posting your batteries make and model number.

    January 14, 2009 at 6:15 pm

    I just wanted to warn people so they don't go through what I did:

    DO NOT buy from Pandora Sales. I ordered the 4 gb magic memory stick, and they sent me a fake card. If you bought from them, test the Magic Gate - if the psp says "unknown" rather than "supported," it's FAKE!

    So they said they'd exchange it. It was a big hassle because I live overseas. And they didn't even refund my shipping to send it back.

    So about two weeks after they receive it, I get my new card in the mail. And it's real!! However, all of the files on the card are corrupted - making it useless for putting CFW on my PSP. I ended up reformatting and making my own MMS via Rain's memory stick maker. Here's some advice - much easier and a lot quicker to just do it yourself. Don't get scammed by Pandora Sales!

    Hi everyone.
    I have done numerious research before buying my ‘PSP 2000′. Anyways got off amazon brand new and guess what….Its PSP-2003. So i have looked around about hacking/flashing it and i am a bit sketchy about what i have to do exactly. I have noticed that ‘out of the box v4.01 CANNOT be hacked due to a new motherboard however i carefully took mine out and checked and mine is 3.95OFW. I have ordered my pandoras battery and MMS via ‘pandoragadgets’ so i have emailed them to check, but can anyone actually clear my problem up for me?….I would like to downgrade.upgrade to CFW on my ‘PSP-2003 v3.95OFW’. Can i do this? If so how? Any feedback much appreciated.

    • Simon Slangen
      January 7, 2009 at 7:48 am

      If you pandorised it using a CFW PSP, you can use the same software to reverse the process.

      With a hardware modded battery, you'll need to solder a bit, and with a purchased TOOL or JIGKICK battery, it's just not possible.

    January 4, 2009 at 8:39 pm

    Great guide,
    Im going to get the PSP 2000 soon with v4.05. I looked at pandoras downgrading guide ( This is becuase i am going to buy both the MMS and the pandora battery. Once i get these should i proceed from (using your pandora battery). I feel your guide is better. Anyways i am not to sure about the downgrade process could you clear a few things i am v4.05 where you say ''go to recover and choose to install the 3.80 Custom Firmware (M33).''. I would like to know if there is any specific reason why that one. And the updating procress. For example if i download any other updates...i could choose ''4.01 M33'' then put that update file here (X:\PSP\GAME\UPDATE). Then continue the process for example? Last but not least if i had the latest update which you talk about in this guide it shouldnt affect the ability to uniquely customise my PSP, and install chat, radio, msn, wifi-catcher, homebrew capabilities onto your PSP so that i can run software straight off the memory card?

    Thanks again, its appreciated. Once again great guide (y)

        there a new rain's mms maker out
        it's rain's ultralite mms maker should i use this one to go from cfw 3.80m33 at the end of your tutorial to get to
        cfw 5.00m33-4 or will the rain's on your tutorial do the job. i got the latest cfw5.00m33-4 from here [Broken URL Removed]

        or could i use the new rain's mms maker to do the hole job?
        I'm at ofw4.05 psp1003 fat I've got all the programs i need including the 1.50 kernel.

    I'm going to use step 3 as i have ordered a datel tool converter. this allows you to make a standard battery into a pandora battery, and back again in seconds (fat or thin). got it from amazon for £8.02 including p+p.
    make me laugh to think that people are so impatient. they just blunder in without reading up on it.(let just rip apart the battery and hack away) lmao

          No way to say that for sure, but it's highly probable.

          If they succeed in dumping the 4.00+ IPL, they'll be able to make a MMS that works with the TA88v3 motherboards. Chances are pretty good that the PSP-3000 will fall somewhere around the same time.

        By the sound of it, you might have a TA88v3 motherboard, unless you're absolutely sure that your PSP didn't came with firmware 4.01 or 4.05 preinstalled

    I just wanted to share the problem I was having and my solution. I got a black screen everytime I tried using my Pandora's battery. I did get a green light, so i knew it wasn't the battery. Turns out windows vista somehow didn't allow me to make a mms. When I tried creating a mms on a xp machine it worked perfectly. Hope this helps!

    • Simon Slangen
      January 1, 2009 at 2:52 pm

      Additional research show that some types of the PSP 2004 can’t be cracked, the ones with a TA88v3 motherboard. These come with Firmware 4.01 or 4.05 pre-installed.

      Your screen will remain black when trying to use a Pandora Battery.

      So basically, you can use any PSP, except a:
      - PSP-2004 with a TA88v3 motherboard
      - PSP-3000 or above

    Thanks for the guide, but I'm having a few issues.

    My PSP:
    OFW - 5.00
    I am trying to get this to work, but I just can't.

    I've recreated the MMS several times and I just get a black screen whenever I insert Pandora's battery. Is there anything I can do? The battery is a 3.6v 1800mAh TOOL.

    I've also tried other programs like "PSP Pandora Deluxe", but to no avail.

    u can make a normal battery and a pandora battery by a single battery by just cutting the line near the 19 in the battery motherboard for the pandora battery and just going over the line with a pencil to use it as a normal battery after....

  234. Joshua
    December 23, 2008 at 10:28 am

    @ ishaan

    Yes, you can buy that battery, but i would only recommend it if you 1:live in america, 2: want to fork out an extra $10 U.S. for a battery that essentially is exactly the same as a datel 'tool' battery (shown in the tutorial) except it can be used as a normal battery also.

    And in answer to your 2nd message
    1: maybe in a store, but definitely online, i suggest going on google and click on the button that searches for sites within your country (i live in australia and we have a 'search sites from australia' button under 'im feeling lucky') to minimise postage and keeping warranty and such. Just search for 'buy datel tool battery' or something along those lines.

    2:option 1 or 2, depending on whether u have access to a hacked psp or not respectively.

    3: yes you can, as long as you dont re-solder the pin

    4:refer to answer 2

    December 23, 2008 at 1:34 am

    Hiya, i get the whole procedure, simple and so-forth, one thing that bugs me is why do i(in making my MMS) have to download the OFW's of 1.50 and 3.80 but no m33 CFW's which I'm going to be getting anyway?

    Thnx in advance for answering and for making this simple for me! =D

    • Simon Slangen
      December 23, 2008 at 7:38 am

      The Pandora Battery uses parts of these original firmwares, not only to 'put together' the custom firmware, but also to change several things within your PSP.

      (e.g. it flashes Phat PSPs with the 1.50 kernel)

      In short, you're just providing the ingredients for a big, tasty CFW pie.

      • Joshua
        December 23, 2008 at 9:03 am

        Cheers, one more thing I missed, when I'm updating my CFW I have to rename them, I take it that the m33 version is the EBOOT.pbp and the official version is the 500.pbp? I know you said to do it like in '2.a' but I clicked on the link and got sent to part-1, then I couldn't find it and got sent on a loop looking through everything, I'm wondering if my phone is being a jerk(I know, I'm forced to use the internet through my phone, isn't that tragic). ANYWAY, could you just confirm or say it's the other way around please?

        Thnx again =D

        • Simon Slangen
          December 23, 2008 at 10:54 am

          Yeah, might get a little confusing.. ^^

    can i use the mms and the pandora battery on my psp normally after downgrading

    • Simon Slangen
      December 22, 2008 at 4:45 pm

      MMS: yes, just format it

      PB: Normally, yes.
      Method 1 can be reversed using the same application.
      To depandorise a hardmodded (method 3) battery, you'll need to do some soldering.

      • Simon Slangen
        December 22, 2008 at 4:58 pm

        My mistake, I meant to say option two. So to make your battery normal again:
        - Method 1: use the same app
        - Method 2: resolder the connection you cut through
        - Method 3: not possible

  240. franco
    December 22, 2008 at 4:36 pm

    • Simon Slangen
      December 22, 2008 at 11:33 am

      The ISO/CSO files should be located in a yourpsp:\ISO folder and you need to have a random UMD inserted.

      You can configure the PSP to boot ISO/CSO files without a UMD inserted, in the recovery menu (hold trigger while booting).

    I have been having a right nightmare with this. But cracked it.

    Im using option 3 with a pandora battery, and making my own MMS.

    What cracked it for me, was turning on the PSP with no battery, just the AC cable. Then once booted up, place the pandora battery in, and remove the AC cable. Follow the instructions above, then when completed, remove the battery, and replace with finger on the L button.

    I also got hold of Windows XP, but didnt try this method with Vista.

      It doesn't matter, but you won't be able to use it as a normal battery.

      The pandorisation (nice word) using the first technique can be easily reversed, but if you decide to use the hardmod technique it won't be that simple.

      Some types of the PSP 2004 can’t be cracked, the ones with a TA88v3 motherboard. These come with Firmware 4.01 or 4.05 pre-installed.

      Your screen will remain black when trying to use a Pandora Battery.

      If your 2004 PSP came with another Firmware pre-installed, you should be able to use the Pandora Battery specified in ifti's link.

        Ok. I got PSP 2004. Bought new, this november with OFW 4.01. After reading whole tutorial and comments I came to know that PSP 2004 OFW 4.01 can be hacked and can't be hacked. Yes, like my comment, its now too confusing to know "Will I be able to hack my psp?" Because I don't know whats my motherboard number (or version). And how you people come to know which PSP 2004 (4.01) could be hacked and vice versa without opening it up. Or rather I should say you open it to know whats exactly does the motherboard says.

        Could you help here because after after applying all the processes and tutorial available on the net, I am still holding my psp with game demos ;)

        I would appreciate to get your fruitful answer, after so much hectic and win less efforts.

          If your PSP came with FW 4.01 of 4.05 pre-installed (and yours does), it can't be cracked.

          The community will catch up, but finding a way to crack these new mobo's takes some time.

      "my psp could crash" "without crashing my pc", please make up your mind, PC or PSP?

      But I guess you just want to get those CSO/ISO files started. If you've got a CFW PSP it'll suffice to put them in a X:\ISO folder (with X being your PSP).

      Please only use these files if you have the original games in your posession. Not just because MUO disaproves piracy, but because it's wrong and you'll burn in hell for it.

          OFW PSP's cannot run ISO's or CSO's (like asking fish to fly). You can use the guide above to put CFW on your PSP.

    Nevermind what I just said, but I still have a problem.

    I made the MMS, put in the batterty, but...nothing happens. It just sits there with the power icon on with a black screen.

    I have a PSP-1001, 1G sony mem stick, and a p.battery. What am I doing wrong?

    • Simon Slangen
      December 13, 2008 at 4:40 pm

      Seems like you're still having trouble making the MMS.

      Are you sure the MMS making went fine? If so, can you give me some more details, I might be able to help you (e.g. slim/phat, serial number, tool/jigkick/hardmod/softmod )

      If you work it out on your own, please offer the solution here for others.

    Alright, I just was able to get my pandora battery, but now I'm having trouble making an MMS. I'm using the standard Sony 1G stick, so it should be fine, but the problem isn't with anything I have. It's the rain maker, because every time I try to load the 3.80 eboot you linked to, I ALWAYS get a "incorrect or corrupted eboot" BS! I don't understand why this isn't working?

          If you made it with through a CFW PSP, try making it using Rain's.

          If you've made it using Rain's, you could try and install one of the other Descartos versions (= other options in Rain’s - e.g. DCv4).

    i am thinking of using option one but the which battery i should be using where is confusing.

    should i battery-mod the CFW PSP (phat) ie. my friends and put that in my psp slim. will that be ok ?

    or do i put my pspslim battery in the CFW PSP (phat) and mod that.

    how do i get the battery back to normal after i have flashed my slim PSP ?

    thanks for the guides.

    • Simon Slangen
      December 13, 2008 at 11:30 am

      Sometimes problems occur when pandorizing slim batteries. Not that it matters, your PSP Slim battery won't fit in your Phat PSP anyway.

      So: Phat Battery.

      Afterwards, the battery can be normalized using the same app. Just start the CFW PSP on A/C power, insert the Pandora Battery, start the application and normalise it.

    i have a psp 2004 with original 5.02 firmware.I did the MMS and i have a pandora battery.But when i put the pandora in psp and i press the L button the green light turns on and nothing happens the screen stays black.Can you help me pls.

    Thanks in advance and keep it up.

    • Simon Slangen
      December 13, 2008 at 11:25 am

      Your pandora seems to be working (your PSP turns itself on when inserted, right?) so the problem is with your MMS.

      Are you sure you've done everything correct? If not, try again.

      Alternatively, if you made it with a CFW PSP, you can try Rain's Simple MMS Maker.

      Your last option would be to try and install one of the other options in Rain's (e.g. DCv4).

    i found out that my battery is pandora proof so i cannot hardmod it.
    in my psp battery even if remove the whole ICO4 the battery works like a normal one.
    my psp battery is :- model psp-S110 Li-ion battery pack 3.6V=1200mAh
    so anybody having such type of battery don't try to hardmod it and try softmod method
    it may work am not sure.

    December 8, 2008 at 11:02 am

    Very nice guide! The best and most informative that I have seen. I just got a few PSPs on Ebay and managed to repair one so far. I upgraded to 5.02 to play with it till I got a good MMS and battery. I now have a MMS and I modded my battery and I can get to the menu to intall CFW 3.80. My battery wont charge, I can run my PSP from the A/C or USB charger but if it is unplugged then it shuts off. It will be at least a week before my new batteries get here and I want to play with the newest CFW now. My question is if I can get to the menu to install CFW 3.80 will I need a charged battery or will it just install using the A/C power? Also if I am running CFW 3.80 can up upgrade to CFW 5.0 without a charged battery or will it be like the OFW and require a fully charged battery to upgrade?

    • Simon Slangen
      December 8, 2008 at 11:28 am

      In theory, you can do both these things with just your A/C power, but for safety reasons (you're working with delicate parts of your system), some apps do require your battery to be charged over 80%.

      My guess is that you will be able to install CFW 3.80 with your A/C power (if you can get into the menu), but the CFW 5.0 upgrade will require a charged battery.

      I'm not 100 procent sure though, so you can always give it a shot.

      • opy
        December 8, 2008 at 11:37 am

        Thanks, that answered my question. Now to decide if I want to install 3.80 and play the ISOs I have or wait till a battery gets here next week or wait till I fix another PSP and experiment on that lol. One more question, I assume that withg the CFW you cannot access the PSN or do remote play right? If not I will just wait till I get another PSP working so I can have 1 original and 1 CFW.

        Thanks for all your fast, helpfull advice and this awesome tutorial! And I am extremely impressed with your patience with the noobs that cant read the entire tutorial before asking noobish questions lol.

I assume witht the CFW you cannot access the PSN or remote play, am I correct? If this is the case I will probly just wait to repair another PSP and have 1 OFW and 1 CFW.

    Hi Simon,
    Check this excerpt. is it possible to modify a battery without opening it (Hardmod), just by using a software? someone sent this to me.
    Thanks for your previous reply. Keep up the good work. Cheers!
    ""- A spare PSP Battery. Any make will do. Using a spare is best, as it
    will not be possible to boot the PSP in its normal state with the
    modified battery.
    - A spare Memory Stick Pro Duo of less than 4Gb. (256Mb should be
    enough for all applications).
    - A PSP with a Custom Firmware such as OE, M33 or WC, or a PSP with
    the 1.5 original kernel.

    - Connect the PSP to the PC with the Memory Stick inside via the USB
    - Format the Memory Stick using any utility.
    - Use mspformat to format the Memory Stick logically.
    - Remove the Memory Stick and disable the USB connection.
    - Connect the Memory Stick again via the USB connection of the PSP.
    - Manually create the PSP/GAME (optionally PSP/GAME150) folders on the
    Memory Stick.
    - Copy the "battery" and "installer" programs to the PSP/GAME
    (optionally PSP/GAME150) folder.
    - Copy the 1.50 official updater as UPDATE.PBP to the root of the
    Memory Stick.
    - Remove the Memory Stick and disable the USB connection.
    - Run "installer" through the firmware on the PSP. This application
    will create the firmware files on the root of the Memory Stick, as
    well as msipl.bin.
    - Connect the Memory Stick again via the USB connection of the PSP.
    - Execute "msipl" application on the PC with the msipl.bin to write
    the IPL to memory stick.
    - Remove the Memory Stick and disable the USB connection.
    - Execute "battery" application on the PSP to modify the battery.
    - Congratulation, you are now in posession of a "Magic Memory Stick"
    and a "JigKick Battery".

    - Insert Memory Stick into the PSP
    - Remove power cord and insert the JigKick Battery into the PSP.
    - A menu appears when the PSP boots. Follow the onscreen information
    and instructions.""

    Simon or any who can answer this question,

    Do I need to get a modded battery before making the magic memory stick or can i get it afterwards? and Once i have completed this entire process, will running the psp with a different battery or memory stick screw with the updated firmware?

    Thanks in advance. This guide was truly helpful, insightful, and creates almost no possibility for user error.

    • Simon Slangen
      December 8, 2008 at 2:10 am

      You can create the MMS afterwards, but you won't be able to start your PSP with a Pandora Battery, so you'll need to:
      a) Create the MMS, then the Pandora Battery
      b) Create the Pandora Battery, then the MMS, but don't restart your PSP in between
      c) Create the Pandora Battery, then the MMS with a different battery
      d) Create MMS with Rain's Simple MMS Maker and the Pandora Battery whenever you want

      When you have completed this proces, you can restore your battery and use any battery/MS your want.

        December 8, 2008 at 9:17 pm

        Well im choosing to go with option three meaning that i'll just purchase a Pandora battery rather than make my own. So i was just asking for further clarification:

        A. Can I create my MMS with the Rain app now with a regular battery? because im prepared to make the MMS now but i need some time to get the Pandora battery.

        B. If I can, will that MMS be functional with regular firmware for the period of time until i get my Pandora battery?

        C. And after i complete the process and have installed custom firmware, i switch back to my original battery but the i can keep the MMS and use it regularly?

        Thanks again.

        • Simon Slangen
          December 9, 2008 at 5:07 am

          The only thing special about a MMS are the files that are on it.

          A. Yes

          B. Yes, but you would need to make it again once you've got your battery. (you need a 'clean' MMS)

          C. Like said above: "The only thing special about a MMS are the files that are on it.", so if you format it you'll have a normal MS.

        • wh1t3b01sl1m
          December 9, 2008 at 7:28 pm

          A Pandora battery only puts the PSP into some kind of service mode, so I can not go into USB mode with one, correct? and So long as I don't save anything new to the MMS, it remains "clean", correct?

          I apologize for asking so many questions.

        • Simon Slangen
          December 10, 2008 at 5:03 am

          No probs,

          Normally your PSP boots from the flash memory, with the Pandora battery it boots off the MMS instead.
          You should be able to use your Pandora if you start your PSP (with the A/C adaptor) without the battery inserted. Once started up, you can insert your battery and remove the cable. I'm not sure if this works with TOOL/jigkik batteries, though.

          About the MMS, just don't use it. You won't be able to play video's from it, save games, etc. without screwing it up.

          If I were you, I'd wait with the MMS until the Pandora arrives. Making it is really simple and goes rather quick.

      If your battery is made correctly, your PSP should turn on automatically. If this doesn't happen, and if you can start your PSP like normal, there's a problem with your battery.

I read your comments but there was no direct method for me to follow based on my software version upgrade and battery type. Could you please help me by giving me a step-by-step guide on how to START and FINISH this process. I greatly appreciate all you have done and will also greatly appreciate any help you can give me.

      You can follow the guide above.

      You won't be able to convert your battery with Pandora Installer, though. Your options are:
      a) Buy a TOOL/jigkik battery
      b) Hardmod your battery or
      c) Use someone else's (phat) battery with the Pandora Installer.

      As I have told before, FirmWare version does not matter. All that matters is your PSP's version (no PSP-3000)

        "I also don’t have any friend who has a downgraded PSP to assist me.
        PLS help!

        Your options have then decreased to:
        a) Buy a TOOL/jigkik battery or
        b) Hardmod your battery (and buy a new one)

        Because one costs about as much as the other (but hardmod isn't always performed correctly), I'd advice you to buy a TOOL/jigkik.

      A little more specific? What technique did you use to make your MMS?

      If you used a CFW PSP, try Mark Ashton's suggestion and run the MSIPL command while making your MMS.
      Does it work now? (if it works I might have to make a modification to the guide)

      If you used Rain's Simple MMS Maker, try my suggestion to Adam (a few posts up)

      Let’s try to install another version of Pandora (the original one). We’ll use Rainman’s MMS Maker.
      1) I suppose you already have Rainman’s MMS Maker. Otherwise, download it now.
      2) Download the 1.50 OFW if you haven’t got it already. link
      3) Select the target drive (PSP). To do this, you either need to use another (CFW/OFW doesn’t matter) PSP, or a MS Pro Duo reader/adapter ((example).
      4) Select the ‘Format’ checkbox.
      5) Press ‘Make MMS’

    Scroll up and read my post, I had the same prob as you. I think there's a step missing in the otherwise excellent guide above as I followed it exactly and it only worked after I 'fiddled' (see my post for details). I think you need to run the install MSIPL command after you've installed the DDCv4 MagicStick file (from what I've read this is needed to get the PSP to boot from the mem stick once the Pandora battery fires it up - correct me if I'm wrong Simon as I'm only just learning about this side of things so it's the blind leading the blind - all I know it that it now works!). When I have more time I am going to follow the guide again now I know what I'm doing and make 2nd Mag Mem stick (as I think this was the problem) using the guide. If it doesn't work I'll try each of my tricks in a row until I work out what it was that did it, then we know what the missing step is...or isn't! Main thing is, if you get the green light when you put the battery in you know the battery side of things is working correctly. By process of elimination this means that either the memory stick is not prepared correctly or FAILS TO BOOT (which I think may have been the prob)... You will prob need another PSP battery to get it to boot so you can get back to the Memcard maker screen as Pandora's Battery won't let you boot normally

      yodiddyumm has a jigkik battery (like a TOOL). This means he'll have to use Rain's Simple MMS Maker, which 'injects' IPL by default. Hence, this isn't the problem.

      Which does not mean it's not "a" problem. I'll look into it.

      "if you get the green light when you put the battery in you know the battery side of things is working correctly."
      "that either the memory stick is not prepared correctly or FAILS TO BOOT"
      Which is kind of the same thing, but correct as well.

    i have PSP 2004 slim ice silver with ofw 5.00, how to play ISO/CSO games on it ?
    do i have to install cfw on it ? and please tell me how to install.
    please help.

    • Simon Slangen
      December 6, 2008 at 3:18 pm

      Yes, you'll need to install CFW on it. If you scroll up you'll see a how-to.

      There are several tools available to back-up your UMD's (like Fastloader or UMD Ripper). These can then be booted by dropping them in an ISO folder on your Memory Stick (X:\ISO).

      Try to use legal back-ups, game earnings are pretty harsh as it is.

    I followed your guide to the letter but ended up with black screen and green light. I tried again several times and was about to give up. I've now got it working, it started with just getting the Elf menu up so I started again as I realised I now had a working pandora battery. Not quite sure what I did as I'm not sure whether it was the battery side of things or the mem card, but here's what I'd been through and then it started working as some troubleshooting tips:

    I normalised the battery again (it's easier if you have a 2nd battery to boot PSP although you may get it to boot on AC)
    I re-partioned the Mem card as instructed in the guide which wiped it again
    Then installed the pan3xx folder as per the guide along with the 150, 340, 380 and 4.01<which is not mentioned in the guide but comes up as 'missing' when you load the installer off the card
    I ran the installer
    I pandorized the battery FIRST (backup and make a note of the the settings)
    I used DDCv4 (but this time left off Elf & NAND tool)
    I also went back into the MemStick and MS-IPL options and ran the install MSIPL command < which appeared to make a difference - but I don't know (try it with and without)
    (It may also be worth trying the battery pandorize at the end rather than the start of this list)
    Battery Out
    Battery In
    White menu came up and we were away

    I'm sorry I can't be more specific, but it's late and I've tried 100 things to get this working, maybe I'll have another go once I get my new battery and let you know what was going wrong... suspect it may be one or more of the steps above that you need to do in addition to the guide... Best of luck! Mark

    I bought another 2004 PSP running CFW 4.01 M33-2 and I would like to ask is it upgradable to CFW 5.00 M33-3 and if your answer is yes how to do it and do you reccmend to upgrade it (i.e what makes 5.00 M33-3 superior to the CFW i am using now). Thanx again

    • Simon Slangen
      December 3, 2008 at 5:45 pm

      Yes. You can just follow the Upgrade to the latest Custom Firmware tuto at the bottom of this guide.

      You don't have to update, but it certainly won't do any harm.
      Because 5.00 M33-3 is more(/most) recent it includes bug fixes, general improvements and
      all new features that are included in the official 5.00 upgrade.

          No sorry, the PSP-2004 with TA88v3 (these come preinstalled with FW 4.01 or 4.05) are also non-crackable, but since you have a PSP-2010 there's nothing you should worry about.

    I have followed your guide step by step using a friend's PSP with CFW and after inserting the Pandora battery and MMS into my Slim PSP power light turned green but no black and white screen showed up even with holding L button. I used Rain's Simple MMS maker and still the black and white screen did'nt show up.
    One more question: How can i restore the Pandora battery to its previous condition(Normal battery)
    my PSP is 2004 and running OFW 5.01.
    looking for your help, thanx

    • Simon Slangen
      December 3, 2008 at 9:52 am

      Possible reasons it did not work:
      - Something was not done correctly
      - You have an incompatible PSP (e.g. 3000 or NAND problems) /Battery/MS

      To restore the battery's original state you can use your friend's CFW PSP and the Pandora Installer app (the one you used to create it).

    December 2, 2008 at 2:43 am

    Alright, I have a few questions.

    First, the image you give of the PSP number on the bottom. Is PSP1001 the PSP-3000 or am I retarded? lol Just a bit confused on if a PSP-3000 has the 1001 on it, because mine does.

    Second, I couldn't get myself a 1G pro duo stick, so I've decided to use the one I already have. At first, I wanted to get a second stick for the MMS, but after looking around I found it difficult to find a decent price or the 1G version at all. At least on ebay. So I got a 2G. Thus, I now have the 1G.

    The problem is that I've already updated my PSP to 5.01 and when I click on the memory stick info on the PSP, it shows me the 5.01 update. So, if I want to make this stick a MMS, would I have to delete the upgrade from the stick manually or just delete it off my PSP?

    • Simon Slangen
      December 2, 2008 at 1:46 pm

      It's just an example as of where to find the serial number. Just make sure yours doesn't start with PSP-3 (e.g. PSP-3000 or PSP-3001).

      1G or 2G doesn't really matter, but you should try to stay beneath 8G

      You won't be able to make a MMS with your PSP. You'll need to use another CFW PSP (one that is already cracked) or use one of the other methods (use Rainmaker's MMS maker and hardmod your battery or buy yourself a TOOL battery).

  314. Adam

    I have a 16GB Lexar magic memory stick that I created using Rainman's MMS maker. I also have a Pandora Battery

    I hold the left trigger button as I press power and this screen pops up..

    Tachyon = 0x00500000, Baryon=0x0022B200
    Pommel = 0x00000123, Syscon DK = 0x7FFF
    Nand size = 67108864
    Model: PSP Slim (TA-85)

    Press X to install 3.80 M33
    Press 0 to install original 3.80
    Press [] to dump the nand
    Press L+R+ start=home to restore nand dump phisically (dangerous!)

    Then I press X and it starts flashing and after about 15 - 20 seconds it says
    PSAR decode error, POS= 0x0075FCDO
    then the psp turns off.
    I tried putting the original battery in and turning the psp on.... The light stays green for 5 - 10 seconds and then turns off..

    Please help

    • Simon Slangen
      December 1, 2008 at 2:26 pm

      A few things you can try:

      option a) Make a MMS with a smaller memory stick (4GB or below)
      option b) Try [Broken Link Removed]

      If this doesn't work, you've probably got a hardware/NAND problem.

      What did you use to make your Pandora Battery? Hardmod or TOOL battery?

      You'll need another battery.
      If you can't boot with your original battery, try with your MMS removed. If that doesn't work, try to install the OFW 3.80 with your Pandora ( 0 in the menu ). Does that work?
      If it works, it won't be too hard to downgrade further using aprevious Pandora version.

      Please keep me updated.

        If I do have a hardware/NAND problem, is there any known fixes for this?

        • Simon Slangen
          December 2, 2008 at 10:15 am

          You've tried to install OFW with your TOOL and MMS inserted?
          Booting with your normal battery and without MMS does not work either?

          Let's try to install another version of Pandora (the original one). We'll use Rainman\'s MMS Maker.
          1) I suppose you already have Rainman's MMS Maker. Otherwise, download it now.
          2) Download the 1.50 OFW if you haven't got it already. [broken link removed]
          3) Select the target drive (PSP). To do this, you either need to use another (CFW/OFW doesn't matter) PSP, or a MS Pro Duo reader/adapter (< [Broken Link Removed]
          4) Select the 'Format' checkbox.
          5) Press 'Make MMS'

          This will bring your PSP back to OFW 1.50. If you get there, you can go any way you want.

          Keep me updated.

      December 1, 2008 at 11:23 am

      A little patience never killed anyone, you can't seriously expect me to reply within 10 minutes after you've dropped a comment ;-)

      Just follow the exact instructions:
      - Download Rains MMS Maker
      - Download the OFFICIAL eboot files of FW 1.50 and FW 3.80

      - Select the 'DCv4' option from the drop-down menu at the top.
      - Press 'Load EBOOT' and locate the 3.80 OFW file.
      - Check the box next to 'Format......'
      - Check the box next to '1.50 Kernel addon installer' (because you've got a Phat PSP)
      - Press the '1.50 EBOOT' button and locate the 1.50 OFW file.
      - Press the 'Make MMS' button and wait for it to finish.

      Option three means you'll have purchased a TOOL battery. Once you've got one, insert your memory stick and the battery.
      Your PSP will turn itself on by default. Just follow the on-screen instructions to install the 3.80 CFW.

      Once you've installed CFW 3.80 (using your TOOL battery and your MMS), you can follow the instructions in the 'Upgrade to the latest Custom Firmware' section to (guess what) upgrade to the latest custom firmware.

      I hope this helps you, if not drop a comment.
      (it is possible your comment doesn't appear instantly, this is because every first comment needs to be moderated by either Mark or Aibek. Be patient. ;-) )

          Just install the official 3.80 FW, no harm done.
          Afterwards you can access usb to make your MMS, use your TOOL and MMS to install the custom FW.

      CFW = Custom FirmWare, this is a PSP that is already cracked. To use option 1 you'll need one of these. Perhaps you can borrow one from a friend?

      If that is not the case, you'll have to go by option 2 or 3.

      November 29, 2008 at 8:02 am

      Your battery seems fine, so the problem should be with your magic memory stick. Try making it again, either with the CFW PSP you used earlier (don't mod the battery again!) or by using these steps, also through a working PSP or using a MS adaptor.

Everything seemed fine until I put the pandora into my Slim to downgrade.. just a green light and black screen. Only now my CFW PSP wont turn on to change anything back because the battery is padorafied.. Does this mean I have to buy another batery to get it back again, or is there something I can do?

    i plug the Pandora battery and it just turn the power indicator green for like ages....
    is this mean i have the unhackable PSP?? or did i do something wrong??? coz you said as long as its 2000 it must be ok
    added details:
    my psp comes with OFW 4.01
    the box says: PSP-2000PB, 100V, G

I have inserted a pandora from a phat and try 2 MMS and same problem, green led on forever and blackscreen.. I still have the warranty so I can't open my PSP to see what is written on the mobo..
          SO unfortunately for us, the few unlucky owners of unhackable 2004 PSP is still hopeleft ,
          #1: so that DARK ALEX will have time to crack the encription of this mobo, or
          #2: to sell the 2004 PSP and buy a brand new 3004 PSP after it can be hacked ( I think that 3004 will be hacked sooner that 2004 PSP w. 088v3 mobo) , or

    Hey Simon, thanks a whole freakin' lot!!! I never thought that I would be able to downgrade out of OFW 5.01. You're the greatest, I've been looking for sites all over to downgrade my PSP Slim and put it into CFW, and I finally found my solution here. WHOOOO!!!!! Thanks again Simon

      I can't find where it mentions the OFW version 5.01 , can i downgrade my psp (2002 model) just the same as you would a lower firmware version.

    Wow - awesome guide man. I think this one is the best one I've come across. I see a lot of people who just struggle with this. I'll have to point them out to this in the future. Keep up the great posts.

    Hi, what about the new PSP-2004 PB-G , can it be "fixed" ? OFW 5.01 ... how do I know if I have that new motherboard that can't be fixed yet? I don't have a pandora or any friend around that have one. Any suggestions? Any advices? THX

      PSP-2004 PB-G ==> PSP 2000 motherboard.
      The only ones that can't be fixed (yet) are the PSP 3000's

      If you don't have a friend with a CFW psp, you'll have to use option 2 or 3

        Thx Simon,

        I'm asking 'cause when I google search for modding the psp, there were ppl who got brand new slim&lite with a TA-088 v3 motherboard on them , and the pandora, time machine and CD was not working.. the 2004 PB-G is quite a new psp slim and that was my concern.. thx again for your answer.

        btw , how can you tell wich m-board is on slim&lite psp's? on the phat it was written on the board and you could see the number under the umd door..

        - later edit.. I forgot to mention, my psp OFW is 5.01 .. I have to downgrade to 5.00 in order to install 5.00M 33-4 ?

          This has been said quite a few times in the comments, but perhaps it's best to say it at the top as well (I can't seriously expect people to read all 250+ comments)

          There are 2 types of the PSP that can't be cracked/hacked atm:
          - PSP-3000 and up
          - PSP-2004 with a TA88v3 motherboard. These are the ones that come pre-installed with FW version 4.01 or 4.05.

          I hope this solves some problems.

      A bit more specific?
      If you mean the firmware files (eboot), download them again. Did you download them from the links we provided? Else, try a google search (e.g. eboot 1.50 download), there are lots of places where you can find these.

      If you are talking about the Pandora Installer you are trying to run on your PSP, are you sure you are using a CFW (already cracked) PSP? If so, try downloading the Pandora Installer files again, or upgrade your CFW firmware PSP to a newer CFW version.

      (please don't update it to a newer official firmware, I'm sure your friend or whoever owns that PSP will be pissed off)

        I have a CFW Fat PSP and a Slim PSP with v5.02 Official firmware.
        I'm done doing everything in option 1 which means I have my own pandora battery and magic memory stick. But, the problem is I don't know what to do next? How can the pandora battery and the magic memory stick downgrade my Slim PSP v5.02?

          if it doesnt work then you have a t8-v3 or the magic mem stick is a bad one try both and look at the battery area if the serial number starts with hu8 its not hackable and there is nothing you can do sorry

      CFW PSP is one that is already cracked. You either need to borrow one from a friend, or use option 2 or 3.

      Good luck.
