Mobipocket Decoder Tool - Page 6

It's possible to patch the 0.02 script to make it work with all the files that work with 0.01. Try the following changes:

Add two lines before line 63 (while True: )

if size <= 0:
return result

Comment out line 72 (while flags: ) and remove one indent tab from each of the following three lines
(if flags & 1:
num += getSizeOfTrailingDataEntry(ptr, size - num)
flags >>= 1)

And that should do it. It's worked on all my DRMed files - around 50 or so, some of which wouldn't work with 0.01 and some wouldn't work with 0.02.

Thank you, Paul! It worked with all of my 49 DRMed files – no switching back and forth between version 0.01 and 0.02 anymore.

Yes, thanks indeed!

I’ve had success with Mobidedrm before, now all I’m getting is …

MobiDeDrm v0.02. Copyright (c) 2008 The Dark Reverser
Removes protection from Mobipocket books
Usage mobidedrm infile.mobi outfile.mobi PID

The result is the same whether I just type "mobidedrm", or "mobidedrm" with input file name, both file names, or the complete statement with both file names and my PID.

I am in the python25 folder and my DRM'd book is in that folder.

Any help would be appreciated. Thanks.

This should only happen if there are fewer than 3 arguments after mobidedrm. For example, mobidedrm A B C should give a different error (no such file or directory A).

Thanks wallcraft,

Yeah, thats right. I get the same message whether I put in 0, 1, 2 or all three arguments.

I use CMD from XP Run. I cd\python25
then I get the prompt c:\python25>
then i type mobidedrm triumph.mobi mytri.mobi BV38BEF$ND

I always get the same message.

When it worked before, it worked on some mobipocket books I downloaded 3 years ago. This is happening with one I downloaded recently. The old ones don't even work anymore.

I uninstalled and reinstalled python 2.5. When I use the python editor and choose "Run", with debugging, it seems to hang on the first line where it says "import sys,struct,binascii". I don't know where this stuff is to import from.

With Python 2.5 installed, I don't need to go to the Python directory. I just have a directory that has the Python programs there and use the command (most of the time)...

Code:

mobidedrm.py DRMladenebook.prc nonDRMladenebook.prc PID

and it works. If it doesn't work, it means I need to use verison 0.01. But with the new fix, I might not need 0.01 any longer.

raymino · 06-24-2008, 11:51 PM

Thanks JSWolf,

I noticed you began you statement with "mobidedrm.py" instead of just "mobidedrm". I think I've tried that, but will try again. I just tried it and same result.

Do I have to have something running in the background? Something that should be in my startup folder?

Try EXACTLY mobidedrm A B C (arguments are "A" "B" and "C") this should not give you the usage message but instead (something like) A not found. If it does give the same usage message, then something very strange is happening. The other thing to try is:

Code:

.\mobidedrm.py "triumph.mobi" "mytri.mobi" "BV38BEF$ND"

The ".\" forces windows to use the copy of mobidedrm.py in the current directory and the quotes should ensure that the command sees exactly the expected arguments.

JSWolf · 06-25-2008, 08:04 AM

I have nothing special running in the background. All I have is Python 2.5 installed on Windows XP Pro.

What happens if you just type python in your command window?

Installing Python on your system should add it to your path. This allows you to execute mobidedrm.py from anywhere.

Depending upon which version of Python you installed, it may have modified your system PATHEXT environment variable to include .py . This allows you to run .py files without specifying the extension; i.e., run the script as just "mobidedrm." You can change this manually via Control Panel if it is important to you to be able to drop the .py.

JSWolf · 06-25-2008, 06:00 PM

I run Python here and have to add the .py to the command. Other then that, it works fine.

raymino · 06-25-2008, 07:42 PM

Thanks to you all for helping me with this. The attached Word file has a screen shot of my commands and the results.

I'm beginning to think that my method for creating mobidedrm.py is faulty. I open the text file in Notepad, I select all and copy. Then I open the Python editor, create new script file, paste, then save to Python25 folder where the drm'd book and the python program files reside.

I think I will try to manually copy the text file with the script, the paste it into the Python editor. Maybe selecting all is bringing over some garbage.

It seems Python is working, and mobidedrm is executing on a limited basis, so I'm thinking that somehow mobidedrm.py is getting screwed up.

Also, do I need to have Mobireader installed?

Thanks,
Ray

JSWolf · 06-25-2008, 07:50 PM

Edit the file with Notepad and see if you've anything wrong in there. If so, fix it. Then save it. There is no need to run it from the Python command prompt. Just run it from a command prompt without using any Python command first. Also try it without the quotes. It could be the quotes around the PID that is causing a problem. But dump ALL the quotes to start with.
