MobiDeDRM for .prc files

I suggest deleting the link, since you probably don't have the right to distribute the ebook.

Three possibilities: a) ebook is DRM-free but uses MOBI-specific compression, b) MOBI is "content encrypted", c) your PID is entered incorrectly on the mobidedrm command line.

For (a), try importing the file into Calibre and reading it. If you can read it, then convert to ePub using Calibre (ePub is just a ZIP file, unzip - edit - rezip - convert back to MOBI).

For (b): MOBI has a DRM mode where there is no PID but the ebook is encrypted and can only be read by MobiPocket's own Reader. See Content Encryption.

If (c) then there are other threads giving advice, but the fist thing to try is put all arguments in quotes (single quotes on the Mac). You could also try pid_checksum.py.

hi WallCraft, thank you very much for your advice.
Dont worry, this ebook is freely distributed.
I can read it on my PC and the other 2 devices.
For your advices:
a) I can't read using Calibre, it told me; "This book is protected by DRM".
c) Always tell me wrong PID
b) IT WORKS

Thank you very much
You are de man

Edit: For my case, my device always display some characters in SQUAREs (I'm not using English)
My solution is to convert to HTML, delete all Fonts Face, then convert back to PRC,
Cheer

What should I do?

I was getting the same error using my mobipocket PID until I renamed the .prc file I was trying to remove the DRM off to something simple like blah.prc. Try taking any spaces/underscores/or any other symbols out of the file name.

I knew my PID was correct and I was running the script properly, when I tried my PID in quotes it just said invalid checksum.. took me a good 2 hours to figure the underscore in the prc file thing out.
