I have downloaded the eBookUtility. I have Java and Python installed on my computer. When I double click on eBookUtility it asks for the serial number (of my Kindle, I assume).

I enter the serial number, taken directly from the back of my Kindle, and it says that it “Cannot generate PIN. Invalid Serial Number?”

Any advice? My Kindle is a Kindle 2 International. The Serial number is definitely correct. I even know its PID.

Many thanks. I want to use your application to strip a Mobipocket ebook of its DRM so I can read it on my Kindle 2.

Cheers, Will

I have followed your instructions, and validated the PID of my Kindle with MobiPocket Reader 6.0 which displays the PID on the screen. I also checked it with the kindlepid.py script going around.

I have the dedrm files in the same folder as the ebook that I want to strip of DRM to make it readable on my Kindle.

I have correctly accessed the folder through the command prompt, I am familiar with using this command function.

However when I follow the instructions of your script, using Mobidedrm, or Mobidedrm002, or Mobidedrm 005, it always responds that the PID is not valid. I have tried it with these ‘ around the PID as you suggest, but it still says the PID is not valid.

I can assure you that the PID is valid. I have verified it through two sources now. Do you have any other advice or is there a fault with the script(s)?

Many thanks
Will

“That file uses an ancient form of MOBI DRM called password DRM. Such files open automatically using mobipocket software so people think they dont have DRM, but they do.”

Not sure how it is they open on the Kindle then. Luckily some of the stores I have contacted have been kind enough to fix the books since they all told me they didn’t have DRM. Two never even responded about the problem and which format I should be purchasing to read on my Mac.

Thank you for creating such an important and helpful tool. I want to apologize in advance if you have previously addressed this issue. Several coworkers and I frequently use Mobipocket Reader 6.2 for Windows, primarily because Mobipocket includes the AutoScroll feature. We find AutoScroll indispensable; it is enormously helpful for speed reading and becoming a faster and more efficient reader.

Unfortunately, it appears that none of the standalone ereaders (including the Kindle) has the AutoScroll feature. Therefore, we’d like to be able to convert Kindle books for use with Mobipocket. Our intent is neither to obtain a book free nor distribute it to anyone else. We simply would like to be able to use auto scroll with books we’ve purchased from Amazon. Until Amazon includes auto scroll on the Kindle, this appears to be our only option.

Can you tell us if there is a method to convert Kindle books for use with Mobipocket Reader without having a Kindle? We are all running Windows 7 desktop computers. Thanks again for your help. If you take PayPal donations for this endeavor, please let us know as we’d like to contribute.

This was my fault, some of the changes I put in caused a few bugs. It was quietly throwing a stack trace and doing nothing else. Please grab the replaced version of the 0.6 release from the post above and give it a go.

Changes:

eBookUtility 0.6 – 10/26/2009
—————-
- Not much new in this release, I haven’t had any reports of bugs, and only one feature request.
- NEW: Added a checkbox to allow overwriting of the source files — many people didn’t like the ‘-stripped’ name addition, and it was easy enough to implement, so now you have it.
- NEW: The DeDRM scripts provided with the utility are now 0.06 so there’s no need to upgrade.

I was able to use the scripts by using a working folder and a .bat file. A clunky process to be sure, but I got what I needed. Thanks again for responding!

First, in terms of the text file, make sure it’s named “ebook.props” and has no “.txt” extension, otherwise it’s not going to be recognized. Also make sure that the format for the serial and pid follows that provided in the readme. This does work, others on here have used it.

Second, it sounds like you don’t have python setup in your path variable. A good way to test this is to open up a command prompt and type in python, if it says command not recognized, then you need to modify your path variable. You can do this by right clicking on “My Computer” and hitting properties. Then go to the “Advanced” tab and click the “Environment Variables” button, find the variable “Path” under “System Variables” and hit “Edit”, then add a “;” at the end of the variable string followed by the directory where the python executable resides — typically “C:\Python26″ (Don’t include the quotes when adding to this variable) — which seems to be the same for regular python (as downloaded from python.org) or activestate python.

I downloaded eBookUtility0.5 as well as ActiveState ActivePython. Because I don’t have a Kindle I created the text file as requested in the ReadMe file of eBookUtility.

When I try to launch the .jar file I get an error “can’t find properties, please enter your Kindle serial number” then it cycles through some other error messages: “no serial found, exiting, DRM functionality won’t work” “python scripts are missing, DRM functionality won’t work” “cannot generate PIN, invalid serial number? DRM functionality won’t work” before going to a screen where I guess you enter the titles you want stripped.

I have tested Python and it is working. What the heck am I doing wrong? Thank you!

I have .PDC file downloaded (protected pdf (by DRM) done by locklizard software)
How can i remove DRM from .PDC files (pdf files) ?
Any code or command that can be used?

Regards
Joy

Thanks again for this great writeup. Took care of my .lit purchases awhile ago, so now I just need to find something to handle my .pdb eReader books…

Let me know how that goes

You can give it a shot with my utility, it makes a graphical, easier process — you’ll need Java installed if you haven’t got it already (odds are you do) — you can get my program from here, just launch the .jar file and give it a go.
