I just bought a book on Amazon, and I would like to read it also on my sony prs. Needless to say, I need to get rid of the DRM.
I use Calibre, so I installed the latest version of the drm tools, all went fine. I installed Kindle for PC on wine-1.3 (both the current updated version and an older one) and I downloaded on the hard drive the book I bought as a prc file (the first time, I downloaded the book on my android phone, with the kindle app, but I did not manage to find it in the filesystem). I thought I read that if you use Kindle for PC, you need nor a serial nor a PID. I just tried importing the book with calibre, but I get this error message
Code:
Error decoding: /home/blabla/My Kindle Content/mybook.prc
the book is in the collection however, so I tried to convert it in order to get some more verbose error message. When I try to convert to lrf I get:
Code:
calibre, version 0.7.58
ERROR: Conversion Error: <b>Failed</b>: Convert book 1 of 1 (BOOKNAME)

So I tried with the commandline directly, using mobidedrm.py
Code:
python mobidedrm.py 1.prc out.prc PIIII\$ID
MobiDeDrm v0.20. Copyright 2008-2010 The Dark Reverser.
MOBI header version = 6, length = 232
Extra Data Flags = 10
Error: no key found. maybe the PID is incorrect
where PIIII\$ID is the PID I got by running mobipocket reader (v.62, again on wine), because I had no other clue where to find the PID.
Any ideas? Even I pointer to where to start would be appreciated.

Your AZW file will be saved in Calibre after you receive the error message with DRM still in it. calibre convert the AZW book to MOBI format, make a copy of the MOBI file where you can find it later, remove the MOBI file from calibre, and then add the MOBI file copy you saved to calibre and I believe you will have a DRM free MOBI file. You should not see any error message when you add the MOBI file this time. You may then convert it back to a DRM free AZW file if you wish. Make sure to first remove the original AZW file from calibre. For some reason this workaround seems to work in Kindle for PC files while the direct DRM removal for AZW does not. |
