Backup, Restore, And Update Android On The HP TouchPad

muo hpt android intro   Backup, Restore, And Update Android On The HP TouchPadIf you’re sick of the limits to webOS on your HP TouchPad, you might have already installed Android Ice Cream Sandwich using the guide published previously.

In most cases, you should have found that this is a great way to breathe new life into your tablet. While webOS has a slick and pleasing user interface, the platform is sadly lacking in applications.

However the versions of Android Ice Cream Sandwich that are currently available for the HP TouchPad are also lacking. In particular, functionality of the camera and microphone has been missing, resulting in a tablet that looks great, has lots of apps but isn’t quite ready to use.

As time progresses, developments to the drivers for these devices will result in a fully functioning Ice Cream Sandwich for the HP TouchPad; but how can you easily upgrade your existing Android installation?

Introducing ROM Manager

Thanks to the ROM Manager utility, you can backup your current Android installation, download and install an update and even restore to the previous backup if necessary.

(The general flavour of what follows also applies to other Android devices, but we’re focussing here on the HP TouchPad.)

Using ROM Manager is pretty simple. The utility offers a range of options, dealing with recovery, ROM management, backup and restore and also offers some additional utilities.

ROM Manager should appear in the Apps list on your HP TouchPad after installing Ice Cream Sandwich. If it isn’t, simply visit Google Play, search for the app and install it.

To use ROM Manager successfully you will need to configure ClockworkMod Recovery. If you followed our previous guide for installing Android on your TouchPad, you will find that this is very simple. Select the Flash ClockworkMod Recovery option in ROM Manager, accepting cm_tenderloin as your “phone model”. Next, the tablet will ask “Have you installed a ClockworkMod based recovery manually?” Select Yes for this option, and then choose ClockworkMod 2.x to proceed.

Backup Your TouchPad with ROM Manager

Before installing a new ROM (the name given to an operating system image), you should backup the currently installed version of Android. In ROM Manager, scroll down to Backup and Restore and select the Backup Current ROM option.

Your device will request confirmation; click OK and the TouchPad will reboot. As it boots up again, the data is backed up; this may take a while, so leave your device alone until the process is completed.

Once done, Android will boot as normal, and you’ll be safe in the knowledge that there is a backup of the OS ready to install (or “flash”) in the event of problems.

Download and Install a New Android ROM

Finding a new ROM for your HP TouchPad is a case of going to download.cyanogenmod.com/tenderloin and selecting one of the most recent – and if you can, stable – nightly releases. This should then be downloaded to your computer, and copied to your HP TouchPad. If you’re mobile, however, you can also download directly to your TouchPad. Save the file in the cminstall folder (created when you installed Android previously) and remove the previous ZIP file if it is still there (from which your current Android installation was installed).

All you need to do now is open ROM Manager, select Install ROM from SD Card, select the appropriate ROM, remembering to select Wipe Data and Cache and Wipe Dalvik Cache before clicking OK.

(Note that in recent builds of Ice Cream Sandwich for the HP TouchPad, the GooManager app will alert you to new updates and download them for you, as well as managing installation. This software also enables you to browse for compatible ROMs which can be installed via the Flash ROMs option.)

Manage and Restore Backups

If there is something about the new ROM that you don’t like, however, worry not – there is an opportunity to restore a previous backup using ROM Manager.

Under the Backup and Restore section, you will be find the Manage and Restore Backups item. By tapping this you will see a list of backups that have been previously created. All you need to do is tap the one that corresponds with the date and time that you instructed Android to make the backup and then select Restore from the menu (you can also Rename and Delete backups using this screen).

Once the selection is made, confirm your choice and the TouchPad will restart; as the tablet boots up again, the backup will be restored!

Conclusion

With the constant development that is taking place in delivering Android to the HP TouchPad, changes are made on an almost daily basis. Nightly ROM builds demonstrate this perfectly, so you should be aware of how simple it is to backup, upgrade and if necessary restore a previous Android 4.0 Ice Cream Sandwich ROM to your TouchPad.

Note that your user data should remain untouched by these changes. Any problems with apps can be resolved by removing them and then downloading again from the Play Store. Using the Downloads menu item will allow you to quickly find software previously downloaded, saving you time.

ROM Manager and ClockworkMod Recovery offer what is probably the slickest upgrade experience of any platform, but remember that problems can occur. In this situation, don’t panic – restart the device, boot into webOS and use the webOS Doctor to resolve the issue.

Thank you, Christian, nice article. I am a bit confused though. How does GooManager enter into play? I thought the ROM Manager was a separate app. I started trying to use that one, and it wasn’t very intuitive to me. So I googled a bit, and found that GooManager was the way to go, so I installed it and this is all I use. Cheers!

Christian Cawley

Hi Leo

GooManager is not given the focus it deserves here simply because its presence on your TouchPad depends entirely on which ROM you update to. We’ll be looking at GooManager separately in a later article.

I agree with Leo, the article is a bit confusing when GooManager is mentioned “out of the blue.” Also, I flashed the latest cm -9-20120715 using ROM Manager. All went well but after I rebooted my HP Touchpad into Android, I checked the “About tablet” in “Settings” but it still shows 9-20120329-NIGHTLY-tenderloin. I also used GooManager to flash the latest “nightly” but, again, “About tablet” says 9-20120329-NIGHTLY-tenderloin. Any thoughts? Thanks.

Christian Cawley

Hi Mark

Are you sure you’re flashing the correct ROM? The best way to ensure that the system picks up the correct one is to delete any others that remain before downloading again.

Mark

I’m pretty sure I’m downloading the right one because cm -9-20120715 is the only zip file in my cminstall folder. Can you check if your Touchpad shows the latest version in “Settings/About Tablet?” Thanks a bunch.

Mark

Update. After doing some checking, I found out that my cm -9-20120715 update in GooManager folder wasn’t the right size. I downloaded it again, used GooManager to install the update, and now I can see the updated install in “Settings/About Tablet.” Thanks for your Install & Update Android on the HP Touchpoad articles!

Mark

I am running into the same issue as well and I am using ROM Manager. My only zip file in cminstall is the nightly build of 7-15 but when I check the version using about tablet it shows prior build of 9-20120329-nightly. The system seemed to flash quickly (tried several times).

Mark

Different Mark with the same symptom.

Mark

Mark, I never got (just) the ROM Manager work to update the build. I was experiencing exactly the same thing you described in your post. I use it for back up only. I’ve used GooManager app a couple of times and so far so good. However, during the process of using GooManager to update the build I see that the screen changes to DOS type menu with ROM Manager icon on the bottom. Hope it helps. Mark.

Mark

I found the issue. In order for ROM manager to perform backups or flash you must choose
ClockworkMod 3.x.I now have a working version of ROM Manager.

Christian… I enjoy reading your posts and without your cminstall instructions I would still be on WebOS. Please update Flash ClockworkMod Recovery version to 3.x and you are good to go.

In ROM manager, Christian, you showed us to choose ClockworkMode 2.x rather than ClockworkMode 3.x when select flash ClockworkMode Recovery. When are we starting to use version 3?
I am a little confused.
Thanks

Hi,

I am newbie so please bear with me in case my query is very primitive. I brought this touchpad yesterday and its having following config –
cm_tenderloin android version: 4.0.3 kernel version 2.6.35-palm-tenderloin CM version: 9.0.0-RC0-Touchpad-alpha1 built date: feb 2012 build number: IML74K.

When i am trying to backup my existing ROM using “Backup Current ROM” option in ROM manager it does ask me to select a name for the backup and reboot the device. But one i am in side the ROM manager after reboot, it gives me error “SDCard needs to remount to use ROM Manager” and doesn’t show anything (but dark gray blank screen) in “Manage And Restore Backups”. How could i make sure if my existing ROm is saved and i can go ahead and install the new nightly builds? I dont want to go ahead and install new build unless i make sure i can recover in case something goes wrong.
Also, can i directly upgrade the build cm-9-20120727-NIGHTLY-tenderloin.zip (July 27 2012) eventhough i have 20120219 (feb 2012) right now? Or i need to go sequentially and update the builds from mar, apr, may…?
Thanks.

Christian:

As others have said, I could not get the ROM Manager backup or install to work until I change the ClockworkMod to 3.x.

As soon as I did that, everything worked perfectly.

You are really doing good work with this!

Is there any way to know what is being changed with the nightlies?

Thanks.

Jim

Hi Jim

At present the automated nightly builds have been brought to a close, so I’m keeping an eye out for the ultimate ROM release (working camera, of course) and I’ll be updating things here.

You can keep an eye on things at XDA: http://forum.xda-developers.com/showthread.php?t=1568685

Looking forward to the working camera!

Thanks.

Hi Chris & Bakari,

I have updated with the tenderloin like you told me and have even tried to do what you have said here but when I hit Install ROM from SD card it says ” Only Premium users may use Alternate recoveries with ROM Manager to flash Roms! Otherwise, you must have ClockworkMod Recovery installed before continuing! Install the recovery through ROM Manger first.” on Check for ROM Updates it stated “Error while downloading from server. Please make sure that you have a stable internet connection, and that your SD card is inserted and has free space.” Received the same message when I hit Flash ClockworkMod Recovery…. Help Wifi is not working but it was yesterday when I downloaded the android.

Any word on when we will get a release that will have a working camera?

For my use, that is the only thing that is not functioning.

Thanks again for all your help. It really made the Touchpad fun to use!

Hi Jim

Unfortunately we’re still waiting on that. it might be the case that no camera support is ever forthcoming.

Thanks Christian –
I have updated via ROM manager using the latest nightly build and all seemed to go perfect. However, I now do not have any apps that I had previously and my linked accounts are gone as well. I don’t even have the icon for the google play store. If I browse to the google play store via the browser and try to install the app it says that I already have it. I figured that I could go back to my ROM back up but that has disappeared as well. I am stuck

Hi Christian,

Whenever i click on Flash ClockworkMod Recovery it gives me an error saying cannot download from server as my wireless connection is not working. I also tried to upgrade to the current nightly build by selecting install rom from sd card and cannot upgrade as it says you must have clockworkmod recovery installed first. Any ideas how i can proceed to upgrade to the 0930 nightly build to fix my wireless problems. Many thanks.

Christian Cawley

Hi Bob

Boot back into WebOS and follow the instructions in the guide, but instead of the Android version I suggested, copy your preferred build into a new cminstall folder (insure previous is deleted and/or contents have been removed). Proceed through the guide issuing the novacom command in the command line, etc, and this should install the fixed build.

Hi,
unfortunately i’ve choosen on the first run of ROM-Manager (for backing up the actual Rom) the wrong ClockWork-Mod ( Version 2 instead of Version 3). If i try to make a backup, the pad reboots (no mor question about the version of the CW-Mod) but do nothing (no backup at all). How can i change the version of the installed CW-Mod for the ROM-Manager?
Tx,
chris

I`ve recently installed Cyanogen mod 7.2 on my girlriend`s HTC Wildfire and after the reboot the SD card is not recognized. How can I fix this?

Christian Cawley

I would advise heading to xda-developers.com for answers on the HTC Wildfire. This comment thread is for installing Android on the HP TouchPad

Hello Just curious on updating, just pick Mod3x+ instead of Mod2x+ and the backup and update will work?

Gary

Christian Cawley

I’m assuming you mean in Clockwork? If so, then 3x is fine. If not, please be more specific :D

Gary

That was ClockworkMod 3.x. All went ok after picking that option

Thanks
Gary
