Re: skindle - remove DRM from KindleForPC ebooks (mobi and topaz)

John-K9jgs · #1 07-12-2010, 07:53 AM

I think I have done what is required, extracted Skindle into a file on my desktop, copied the book title into the Input folder, and (maybe not needed) downloaded Kindle for PC to my machine.

However, the Output file remains empty when I try to use either LZ or EZ. I am not very sophisticated with this stuff so I don't know where to look for the problem.

Any suggestions will be appreciated.

Hoping someone might be able to point me in the right direction...I have been using the free Kindle app on my iPhone for a couple of years now and have built up quite a library of Kindle books, but don't have a physical Kindle. I am looking at buying the Sony ebook reader and want to be able to read my Kindle books on it.

I've installed Kindle For PC and skindle and each time I run it I get the error no valid pids available failed to find drm key. I'm wondering if this is because I don't have a Kindle device but have just been using the iPhone app instead?

Does anyone have any ideas on how to get around this?

Got "missing exth header" trying to remove DRM from a mobi .prc file.
Worked fine on others. Bought books in protected mobi format, removing DRM before I suck into Calibre.
skindle -i xxxx.prc -o xxxxx.mobi -p mobipidxxx
Worked fine on others.

Where does Kindle For PC (Version 1.2.0) put the ebooks that you download? I can't seem to find them. Using the files that were downloaded for my Kindle give an error message because they have a different PID.

Hi,

I just downloaded a book from Amazon to my pc (windows xp) and I am trying to remove the drm (with skindle) without success. This is a replica of what I get on the screen:

Code:

skindle -i xxx.azw -o xxx.mobi
Attempting to locate kindle.info
Found kindle.info location
Using UserName = "Void"
Using SystemDrive = "C:\"
Using VolumeSerialNumber = "NNNNNNNNNN"
Device PID: XXXXNXXX
PID for xxx is: YYYyYyyY
Didn't find PID magic numbers in record
Found a DRM key!
634702b65r3829g3
Parse Error : Failed payload read of record color: 1 offset 0x4de592:0x0

and then windows sends a pop-up telling me skindle has made an error and has to close. This has happened several times already.

Anybody knows what I'm doing wrong, or how this could be solved?

Thank you very much in advance,

Simon

I just had a similar experience & here's what I've done (no solution yet if ever). When I DLed the book to K4PC it showed as a .azw type but when I DLed it to my computer for transfer to Kindle, it showed as a .tpz file. This seems strange to me. Is it an AZW book or a TPZ book? Still investigating. Will DL directly to Kindle (once the battery is recharged), transfer to computer and see what it looks like.

Edit: The ebook brought in from the Kindle had the extension of .azw1. Apparently this is a Topaz ebook and skindle is not working with it. I had my doubts that it would work with a Topaz ebook but this is the first one I've bought to try it with. A .azw ebook purchased at the same time had no problem with skindle.

Does someone know what they use instead of CryptUnprotectData on the Mac?

I checked skindle and a few things that are different for sure:

The kindle.info is located here:

Code:

/Users/x/Library/Application Support/Amazon/Kindle For Mac/storage/.kindle-info

string_32 is the same, but string_64 is different. The correct string is:

Code:

"ZB0bYyc1xDdW2wEV3Ff7KkPpL8UuGA4gz-Tme9Nn_tHh5SvXCsIiR6rJjQaqlOoM"

From there I just have no clue what they use instead of CryptUnprotectData. The other info was available using lsof/opensnoop and strings.

Try to use the following:
DeDRM AppleScript for Mac OS X 10.5, 10.6

Did you manage to get to the bottom of this?

I've got the same problem (with a slightly different code at the end "offset 0xcd24fc:0x0"). I've got a Sony Reader and bought a book that was only available from Kindle Store.

Seeing as beating the drm of Adobe Digital Editions had been so easy i just assumed that i would be able to figure this out too. It's been driving me up the wall tho!

Any help from anyone would be greatly appreciated. I am running skindle from the command prompt on a Vista machine.

I FINALLY got my file working using this...

and the PID that skindle provided.
