Circumventing Kindle For PC DRM (updated)

Amazon actually put a bit effort behind the DRM obfuscation in their Kindle for PC application (K4PC). The Kindle proper and Kindle for iPhone/iPod app both use a single "device" encryption key for all DRMed content. K4PC uses the same encryption algorithms, but ups the ante with a per-book session key for the actual en/decryption. And they seem to have done a reasonable job on the obfuscation. Way to go Amazon! It's good enough that I got bored unwinding it all and just got lazy with the Windows debugging APIs instead.

So here you go: unswindle v7 (previous versions: v6 v5 v4 v3).

You'll also need a copy of darkreverser's mobidedrm (check the most recent comments for the newest links).

Put those kids together (in the same directory) and run unswindle.pyw. It launches KindleForPC.exe. Pick the book you want to decrypt. Close KindleForPC. Pick your output file. And enjoy the sweet taste of freedom.

Script name in honor of rms and The Right to Read. Don't use this to steal, or I'm taking my toys and going home.

Updates. It came to my attention that unswindle version 1 did not work if KindleForPC was installed as a non-administrator and did not work on versions of Windows other than XP. Version 2 should fix these issues. Version 3 fixes an intermittent path-getting issue. Version 4 fixes an exception related to opening thread handles, detect Topaz format books, and detects that you have the proper version of Kindle For PC installed. Version 5 works with the new (20091222) version of the K4PC executable. Version 6 cleanly handles already DRM-free files.

Update 2009-12-22. Amazon has demonstrated that they (unlike Adobe) take their DRM seriously: they've already pushed out a new version of K4PC which breaks this particular script. As you can clearly see via their SHA-1 hashes:
fd386003520f7af7a15d77fcc2b859dd53e44bc1 KindleForPC-installer-20091217.exe

13a816a3abf7a71e7b6a55228099b03b1dc3789b KindleForPC-installer-20091222.exe
The application doesn't seem to auto-update, so if you can find a copy of the original installer you should be fine. Otherwise you'll have to hang tight. Newest unswindle version detects if you have the wrong K4PC executable installed.

Update 2009-12-22 (2). The K4PC update may not actually have been targeted at unswindle, as Amazon seems to have done nothing in particular to make the basic approach more difficult. In any case, I've updated unswindle to handle the 20091222 version of the executable. We'll see if Amazon throws out another new build in short order, and I'll put some more elbow grease into figuring out the PID-generation algorithm.

  3. I am using Windows 7 Ultimate. The script attempted to open K4PC but I got the same errors as the first version (line 629, debug error, etc). I opened K4PC first, then ran the script and got a Failed To Determine Book Path. An I doing something wrong.

  5. Thanks for all your hard work on this. I just converted my recently purchased Amazon (Kindle for PC) book to a mobi file, then to a pdf using Calibre. Now I am free to enjoy my book the way I choose. I used unswindle.pyw ver 3, Python ver 2.6.4 and mobidedrm ver 0.07 on windows XP. Graham

  8. I've been using Darkreverser's mobidedrm version 6 and it works great. I've got Python 2.6 up and running. I'd understand the difference between py and pyw. I've followed the instructions but I get a syntax error on line 1

    What am I missing!!

  10. I tried it and get a message: Error: failed to determine book PID. Python 2.6.4, running as Administrator. I haven't been able to get pycrypto installed. Does this make a difference?

  11. @Ed Bear; Looks like you've got a Topaz format book. I'll post a new v4 RC which detects this cleanly.

  12. hi fantastic watching and reading this progress. Bought a kindle for PC book a week ago and was sorry to find i could not read it on my sony which is the only device i have. Your work sorted it a treat. Got so excited i went straight back to amazon and "bought" a bunch of free books. unfortunatly this time it gives the failed to determine book PID. I then tried to deDRM the first book with the same error which seemed strange. I then copied the mobydedrm and the unswindle.pyw to the directory where K4PC stored the books. your tools worked again. I then tried it with a second book and again got the error. Now again all books are giving this error. Look forward to you solving this issue.

    ReplyDelete
  13. Unswindle v4-rc3 seems to run perfectly, but mobidedrm(07) reports "cannot decrypt topaz format book." Suggestions? Thanks!

    ReplyDelete
  14. Topaz hasn't been conquered yet. Until it's figured out you have to use it on the Kindle products. He changed the script to let you know it's Topaz so you will know it can't be de-drm'ed.

    ReplyDelete
  15. Andrew, many of the free books on Amazon are actually DRM-free mobi, with the AZW extension. Try just renaming one of them to .mobi and if Calibre can read it, then you know if was DRM-free to start with.

  16. i get failed to determine book path.

    reformated for unrelated reasons, run unswidle after proper setup same error "failed to determine book path". what does this error mean, is there something I can do to fix this

    ReplyDelete
  17. I am also recieving the "failed to determine book path" error. any help would be greatly appreciated

    ReplyDelete
  18. WOW!!!! Thank you so much for all of your hard work!!! Now when relatives give me Amazon gift certificates I can buy ebooks with them!

    ReplyDelete
  19. Hmmm.. I was able to "unlock" 2 of the free books from Amazon with this, then left the computer for a while. Tried to do some more books and also got the failed to determine book PID error?

    ReplyDelete
  20. I think I figured out what I was doing wrong. First - open a book with K4PC that has NOT been changed yet. Then use the script and follow the directions. Just did 6 or 7 books no problem :)

    ReplyDelete
  21. Thank you for coming back. I've been aching for someone to un-DRM Kindle4PC. A few of my textbooks for this semester and next are only available on Kindle and dead tree. I have an eink reader already so don't want to buy a kindle, but the $10 kindle book is so much better than a $30 paper book, not to mention it's reflowable and I can more easily make it fit my eslick's screen (unlike ADEPT protected PDF ebooks).

    Cheers! This makes my next semester a touch more affordable, and I can read on eink rather than my monitor!

  26. @stewball; HAHAHA, oh so funny. It looks like most of the news sites are giving credit for the hack and the unswindle tool to Labba. That article even follows a link in a Google Translated Hebrew forum here and assumes this blog is also in Hebrew. So so funny.

    If you look at this post by labba (bottom of the page, dated "12 20, 2009 12:52 am") he gives credit where due. Gotta love the mainstream media.

    ReplyDelete
  27. I read a few of the other articles. Each one seems to credit the hack differently. The funny thing is most of the articles are coming out of the UK, although a reference to a challenge made in a Isreali hack site was cited on one I read.

  29. Hello, thanks for putting the Kindle script out there. I'm having the same issue that a couple of posters on Dec 17 experienced: when I double-click Unswindle.pyw, nothing happens; if I save the file as Unswindle.py, a console window flashes open, but then immediately closes. In either case, the script doesn't seem to execute. I've used both v6 and v3; running XP with Python 2.6.4. Can anyone suggest where I may be going wrong? Thanks!

    ReplyDelete
  30. @chris; Could you open a command line and manually run python on the script? (Something like c:\python26\pythonw.exe unswindle.pyw?) I'd like to know what output it produces.

    ReplyDelete
  31. @i♥cabbages: Would it be possible for the script, once it's finished the decryption and asks for a output file, to automatically bring the requester to the front? As it is, I have to minimize all open windows in order to see it. Just wondering...

    ReplyDelete
  32. @ Cabbage, I tried the command line that you suggested, but received the same results as earlier; the Command Window in the window header did briefly (briefly!) flash up Pythonw.exe Unswindle.pyw, but no further results.

    I changed the command line slightly to:

    C:\Python26>Python.exe Unswindle.pyw (or Unswindle.py)

    I received the following error message:

    File "Unswindle.pyw", line 26
    ' ""
    ^
    SyntaxError: EOL while scanning string literal

    This is the most response I've received when running the script; it just seems to collapse after I try to execute (I've checked the processes running on my system after trying to execute, to ensure that it wasn't running the background, and I don't see the script, or Python itself, running.) Consistently, using Pythonw gives no response that I can see.

    I did de-drm an ereader (pdb) format book, using the eReader2html.py script, to ensure that my Python installation was not corrupted/had issues, and the eReader2html.py ran without a problem and decrypted my book.

    I'm taking the Raw script, for v6, from the link at the top of the page, copy/pasting the entire script to Note Pad, saving the file as Unswindle.pyw, using UTF-8 encoding. I've checked that the file isn't getting a .txt tacked on the end, and when I do look at Unswindle.pyw in Windows Explorer, it's showing as a Python file (31KB).

    Any thoughts where I'm going wrong? Thanks for your help!

    ReplyDelete
  33. @Chris; It looks like you're just getting a corrupted script file. Instead of copy/pasting, either use the "download" link (right next to the "raw" button on the pastie.org page) or just use File->Save (or equivalent) when viewing the raw script in your browser.

    ReplyDelete
  34. You are my hero, not being in the US, the only way to get all Kindle titles is Kindle for PC. And then I can't read on my Kindle. Now I can buy all titles, and deDRM to put on my Kindle.

    ReplyDelete
  35. Oh, and FYI, I'm running Kindle for PC under Wine in Linux, and using Activestate python for windows installed under wine as well. Your scripts work just fine (wine python unswindle.pyw).

    So that's good news for me :)

    ReplyDelete
  36. @Dave; Wine is an intentionally supported platform -- the more recent unswindle versions even include a dynamic patch which allows the most recently-released build of Kindle for PC to run under Wine. But what's the benefit of ActivePython over the python.org Windows builds?

    ReplyDelete
  37. I'm not sure if there are any benefits, it's just the Windows build I'm familiar with (I use it at work).

    Thanks again.

    ReplyDelete
  38. @ Cabbage; Thank you! I wasn't able to download the script using Google Chrome (the browser gave me a translation error -- not certain why, since I don't think it was coded in Hebrew...) but IE pulled it down without a problem. Got it going, works without a flaw! Thanks!

    ReplyDelete
  39. Congrats on the result, but I'm a little confused. What is the relationship between your unswindle.pyw script and the mobiededrm.py script? It appears that both do the same thing: break the DRM on Amazon ebooks.

    Though the DMCA gestapo has hounded mobiededrm from the web, it seems that you're still free. ...wait, is that a knock on your door?

    ReplyDelete
  40. @steve poling; Darkreverser's mobidedrm does the hard work of actually decrypting a Mobipocket/Kindle book, but only once you have the necessary encryption key. Each book downloaded via the "Kindle for PC" application has a different key, unlike other "Kindle" devices which use the same key for all books. My tool automates extracting the encryption key for a particular book and running mobidedrm appropriately.

    Adobe used the DMCA to get my post providing a PDF decryption tool removed. We'll see if Amazon does something similar here. Tor keeps from being too worried about my actual door, though.

    ReplyDelete
  41. YOu are great. I also live outside US, I can an iPhone but kindle for iphone is not av in my locality. You app allows people like me to transfer my titles from Kindle for PC to my iPhone without pain. It works like a charm.

    ReplyDelete
  42. Needs to be run from the commandline it seems. Am running it with a Kindle binary downloaded today. Sadly I get an error that I'll paste below but it does seem to try and work. There are multiple versions of the mobidedrm file out there if you hunt around so I am hoping this isn't the issue with my attempt! I have many many Kindle books and am SO paranoid about Amazon doing something to leave me stuck. Being able to strip them and store would be a huge relief!

    Argh, cannot paste the error(s)! Errors were in line 845, 798, 811, 614, 722, 761, with final being a WindowsError Error#6 handle invalid. Will play more but in any case thank you!

    ReplyDelete
  43. @John; You do not need to run from the command-line. In fact, for Windowsy reasons I haven't bothered to figure out, launching mobidedrm fails if you run unswindle from a command-line session. You should be able to run unswindle by double-clicking on the file in Explorer, and if there are any errors (other than a corrupted script file) it should display them to you in a nice GUI-wise fashion.

    ReplyDelete
  44. I'm really waiting for the Topaz decryption as it seems Amazon knows that this is safe territory now. Unfortunately, the last few books I've purchased have been that format.

  52. hi thanks for the tool, but unfortunately - being completely lay - i have no idea where to start. i see the script, but what is next?
    is it possible that someone who has succeeded puts down step by step how to remove this drm? thanks a lot again.

    ReplyDelete
  53. I run the script and get to an error that basically says that no PID was found. It opens kindle for PC, it runs everything smoothly to that point.

    ReplyDelete
  54. 1. Have K4PC installed.
    2. Run script and it will open K4PC.
    3. Open the book you want to liberate.
    4. Close K4PC, and a box will appear allowing you to save a copy on your computer.
    5. If it's TPZ/AZW1 the script will tell you and it will not be possible.

    I hope this helps. Be sure to have version 6.

    ReplyDelete
  55. Oh yeah, be sure to have mobidedrm version 6 or 7 in the same directory with unswindle.

  65. Thanks!!! Have just succesfully used latest version with mobidedrm 0.05 to decrypt my first ever Kindle for PC download.

    Now I can read Kindle downloaded books on my PDA - you are doing Amazon a great service!

    (I simply wouldn't download books from Kindle if they were locked to my PC / Laptop, but as Unswindle exists I thought I'd buy a book and give it a try.)

    I hope Amazon aren't foolish enough to try to beat this hack as they'll lose my custom if they do!

  67. hi i have a sony ereader and have had the pleasure of using the unswindled, Python and calibre apps to get my kindle for PC book onto my sony. i have however discovered that all is not as it seems. The book is "the girl who kicked a Hornets nest. I am about halfway through the book and got suspicious that i was missing something. I went to the same pages in the Kindle for PC app and found that any sentence written with < and > does not appear on my Sony. In the book any skype type chat is written in this way.

    ReplyDelete
  68. In fact I have found that large porton of a chapter is missing. I would appear as if the removal of DRM did not affect the book but that the import into the sony results in missing text.

  73. Mclabb,

    Thanks for the insight, I'll have to check it out, even though I'm new to this whole Python/Script game.

    I'm confused on these formats. I was under then understanding that:
    .TPZ = TOPAZ
    .AZW1 = TOPAZ
    .AZW = Normal.

    I now have two Kindle books, one being .AZW1 and the other being .AZW. Using this script on both yields a "Unable to work TOPAZ formats". I downloaded my purchases to the Kindle for PC and ran as described above. I run Vista 64.

    Thanks

    ReplyDelete
  74. Hey there! Firstly, thanks for your awesome work on this stuff. I'm an avid e-book reader and I'm getting pretty frustrated with how difficult it is to convert Kindle files, specifically the Topaz format. Is there any updated info on cracking/converting .tpz files? I saw the postings on dark's site but I know next to nothing about Python, so an easier method would be wonderful. Thanks much for any help. :)

    ReplyDelete
  75. P.S. Sorry, my email is madnessism at gmail dot com.

    ReplyDelete
  76. If you look on dark's site, there are exe files that will do the conversion on a windows computer without having to have python. Very easy.

    ReplyDelete
  77. I was hoping it would be easy. All that happens is it pops up a command prompt, then it swiftly disappears, and then nothing?

    ReplyDelete
  78. I have not use the exe files, but I think you must open up a command prompt to run the exe file. It is not a windows graphics file.

    ReplyDelete
  79. Hello, thanks for putting the Kindle script out there. I being able to convert some of the books with your scrip but others I get a message: Error:cannot decrypt Topaz format book. I have Python 2.6.4 and pycrypto-2.0.1.win32-py2.6 installed. Can you tell me why I can decript some books and not others.
    Thanks one more time for all the work you have put in it!

  80. The Topaz scripts are in the darkreverser blog that has been mentioned several times above. It is not incorporated into the scripts available here.

    ReplyDelete
  81. I am running V6 with Vista and it starts Kindle4PC but that's it, nothing else says to select a book or anything, even if I exit Kindle4PC, any ideas?

    ReplyDelete
  82. vdospec, It was confusing for me at first because of its simplicity. Once Kindle4PC opens, it should list the books that you can choose. Click on the one you want to remove DRM from and then quit the application.

    I went to Dark's blog and couldn't find any Topaz scripts. Can someone give me the name of the script I need to be looking for?

    ReplyDelete
  83. @Alicia
    Look toward the bottom of the New Blog comments. There are over 800. Go to the bottom and grab script package 1.7. It has a read me in it to instruct you on running the Python scripts. You need to know how to run Python through command line to make them work.

    Or you can wait another week or so, and they should have the completely Windows program completed so no Python installation or command line skills will be necessary.

  85. I'm having problems with unskindle. It worked when I first used it but today when I open it, I get a quick look of something but it doesn't stay open long enough to do anything with. What can I do? Is there a binaries version?

    ReplyDelete
  86. When you run unswindle, does it open Kindle For PC? Make sure you have a good copy of mobidedrm (names just like that) with the unswindle file. I noticed you called it unskindle. You aren't trying to use Skindle are you?

    ReplyDelete
  87. Nope, I meant unswindle. The unswindle I'm trying to use, I d/l Dec 18th, along with the mobidedrm. I also have brutsbum's (sp?) file of scripts (1.7) in a different location. The unswindle from there does nothing, not even a pop up.

    ReplyDelete
  88. Grab Unswindle v6 from here, make sure the mobidedrm file is with it. Then double click unswindle. It should open Kindle For PC, not a command window (which is what sounds like has been happening. Unswindle has a pyw extension and should open K4PC and nothing else.

    ReplyDelete
  89. I got unswindle v6 and mobidedrm 0.10 The file type for unswindle is python file, not pyw. Is this what is going wrong?

    ReplyDelete
  90. I decided to re-download python 2.6. Tried unswindle again, told me could find mobidedrm. I had version .10 there but I deleted it and used the one from brutusbum's collection of scripts (1.7) and it worked. Unsure exactly what was wrong but thank you for help, stew.

  91. Windows 7 32-bit; Python 2.6.4; Latest Unswindle & Mobidedrm. Two files in same directory. Kindle for PC installed.

    When I double-click Unswindle, nothing happens. No prompt, nothing. Any thoughts?

    ReplyDelete
  92. On the Mobidedrm script v10, just remove the version number. Unswindle looks for a file with the exact name of mobidedrm.py. I'm glad you got it working.

    Nich1701, I think you also have to have Pycrypto installed. I am using Python 2.6.1 and Pycrypto 2.0.1. I am not sure if the version of Pycrypto is necessary for 2.6.4.

    Here is a link for my copy of Pycrypto.

    When you double click unswindle, Kindle For PC should open.

    I hope this helps.

  94. Hi - I am trying to run the python code, but embarassingly cannot find the location of the Topaz book. I have tried windows searching for azw, azw1, prc, to no avail, but I'm sure there's 1 topaz book on my PC via kindle4pc.

    Can anyone point out the location of the files (Windows Vista)?

    ReplyDelete
  95. This script, Unswindle doesn't remove DRM from topaz ebooks. Go to DarkReverser and look at the end of the 1000 post, and get the latest pack of scripts. There is a txt file in that pack that explains what to do for Topaz. If it is a K4PC topaz, use the normal script. If it is a Kindle topaz, use the non-K4PC script.

  96. Hi @cabbge.
    Thank you very much for your program.
    I tried unswindle.pyw several times.
    Each time, I could get a new file without any comment during the process.
    But when I open the file with ebookReader,
    it says "the file is broken."
    Could you tell me how I can get a unbroken file?

  97. not working in Windows 7 Ultimate as well as Windows XP Mode.

    The unswindle v6-rc1 is downloaded as pastie-761825.py. Should I rename it to unswindle.pyw?

    Anyway, if darkreverser's mobidedrm is published as v1.3, v1.4, do we still need to use unswindle.pyw?

  100. Hello:

    I have a Sony 600 Reader and wished access to Kindle's store library as well as Sony's so your script is perfect. However I am having difficulty using it.

    I am running Windows 7 Ultimate 64 bit on an early dual core AMD chip with an NVidia AMD 590-SLI chipset. Perhaps the difficulty lies with that.

    Python 2.6 32 bit is installed.

    When I double click unswindle.pyw Kindle PC opens up and I select my book without difficulty.

    Then I close Kindle PC and a window opens titled
    "Select unencrypted Mobipocket file to produce"

    This window opens in the directory which contains unswindle.pyw in my case:

    C:\My Downloads\ebook\tools\Kindle_Mobi_Tools

    File name field is empty
    Save as type is set to All files *.*

    I can enter any text I wish, for example
    test.mobi

    Once I select the save button the following occurs:

    MobiDeDRM.pyw begins executing but apparently without any data passed to it.

    Here are the field states at that time:

    Mobi eBook input file: C:\My Downloads\ebook\tools\Kindle_Mobi_Tools

    Name for Unencrypted Output File: BLANK

    10 Character PID: BLANK

    I can convert books now after an hour of reading various blogs but it is cumbersome.

    I renamed the scripts to have .py instead of .pyw extensions so that I could see the python output window.

    Now when I run unswindle.py I see its print outputs which give me the PID.

    Then I run a version of MobiDeDRM.py which is compatible as a Calibre plugin after manually configuring it with the PID unswindle found.

    Do you have any idea how I can fix this so that unswindle.py will properly pass data to MobiDeDRM.py?

    Any thoughts and help is appreciated.

    ReplyDelete
  101. Appreciate all the work. Finally got the script (v6) to run as a pastie. Windows XP doesn't seem to start the 'cut and paste' version via notepad. All went well until the output. Unswindle asks where to save the unencrypted file as a .mobi, but then the file isn't there.
    Also, is the output string remaining at the end of the script the device PID? I could use it directly with MobiDeDRM.

  110. Me too. And as far as I can tell, it's not a topaz book. In fact, I've had books which I can unencrypt on some occaisions but not others. It usually works the first time but then not a second time. Re-downloading can help but not always.

    ReplyDelete
  111. Mathew, if your sure it's not a topaz book then just keep fiddling and it will de-crypt eventually. I just kept trying multiple times until it worked. I also tried re-downloading. Opening then closing the book, etc. Not sure if these helped but it eventually worked.

    way around this? Thanks!

    ReplyDelete
  118. Hi Tasha18...

    You don't need to open KINDLE FOR PC in order for Unswindle to do its work.

    You simply have to run Unswindle.

    That makes KINDLE open automatically.

    At the point, you need to open the book you are interested in stripping the DRM from.

    Once the book is open, simply close KINDLE.

    When Kindle is closed, it will take several seconds before a new dialog box opens up. But this dialog box only opens on a clean desktop. In other words, you need to minimise ALL applications, so that your desktop is visible. (I know it's not visible to you, but heck... best metaphor available to me.)

    When the UNSWINDLE dialog opens, it's asking you for a name and location for the stripped file.

    By default, the file will be saved in the MY KINDLE directory. And it will automatically have a .MOBI extension.

    I hope this helps.

  136. Just an update to my previous post: I read through the Darkreverser's blog (what a treasure trove of info!) and came across another user with the K4PC/unswindle issue. His solution was to completely uninstall K4PC, delete the "My Kindle Content" folder and the Amazon folder in the Local Apps directory; then he reinstalled K4PC (beta version), and ran unswindle, which seemed to solve his problem.

    Figuring that this would be the "path to least resistance", I decided to give it a try; lo & behold, it worked - flawlessly!! I can now un-DRM my Kindle content using unswindle with K4PC (beta)!

    Hope this helps those of you with the same issue! FWIW, I'm running Win7 Home Edition with the 32-bit Python 2.6.4.

    ReplyDelete
  137. Be sure to go into settings in v1.0 Beta of K4PC and turn off the auto-update. Then when you run unswindle, K4PC will ask if you want to update, or skip this update. Of course choose skip the update. Then you are good to go.

  145. When I purchase a book, program, CD, DVD, or an iPhone, etc. they become my personal property. I can do whatever I please with my personal property. I can copy it or give it away if I so chose. If someone comes along and tells me that I can not do this or that, they are in fact making a a claim on my personal property. The only way they can make any claim, is to have a vested interest in it. That is the only way they have a right to make that claim. Since they are making a claim of having a vested interest in my personal property, I want to be paid for maintaining and securing their vested interested in my personal property, because involuntary servitude is unconstitutional. What do you think would happen if we all started to send them notice that we intend to start billing then for maintaining and securing their vested interested? Do you think they might stop this c__p?

  151. To Dena and others who struggle with TOPAZ.

    0) Install "Kindle For PC", go to "Archived Items" and download ("Add to home") the book you want to get.
    It will be better(for complete beginners) if you download ONLY the book you want to get, because it will be easier to locate this book later.
    So you should better have this one book in the "Home" tab in "Kindle For PC".

    1) Download this:
    http://www.mediafire.com/?mn3vmttbwrt

    2) Unzip this file to your C hard drive (after this step you will have "C:\tools" folder)

    3) Download and install this:
    http://www.python.org/ftp/python/2.6.5/python-2.6.5.msi

    4) Open "My Computer" and go to C:\tools\Topaz_Tools

    5) Run TopazExtract_Kindle4PC.pyw (just double click on this file)

    You will see a window with 2 input fields:
    "Topaz ebook input file" and "Output directory".

    What to do with "Topaz ebook input file" field:
    Click the button to the right of this field and navigate to "My Kindle Content" folder.

    For example on Windows 7 this folder is located here:
    C:\Users\YOUR_USER_NAME\Documents\My Kindle Content

    On Windows XP here:
    C:\Documents and Settings\YOUR_USER_NAME\My Documents\My Kindle Content

    Replace "YOUR_USER_NAME" with your user name. :-)

    This folder is also easy to find on Vista(I don't have access to Vista to say exactly where this folder is).

    In "My Kindle Content" folder you will have to select the book you want to get (it should be the only book, as you remember from step zero).
    If you see no files, then you should select "All files" in the lower-right corner of the "TopazExtract_Kindle4PC.pyw" window.
    Then select(double click) the book.

    Intermediate step:
    Open "My computer" and go to C:\tools\Topaz_Tools\lib
    Create a folder named "Book" there, so you will have C:\tools\Topaz_Tools\lib\Book

    Let's get back to our "TopazExtract_Kindle4PC.pyw" window.
    What to do with "Output directory" field:

    Click the button to the right of this field and navigate to C:\tools\Topaz_Tools\lib\Book
    This folder you have to choose as "Output directory".

    Click "Start". A few seconds later you will see "Files successfully extracted". Click "Quit".

    6) Run(double click) this file:
    C:\tools\Topaz_Tools\TopazFiles2SVG.pyw

    You will see a window with this input field "Directory you Extacted Topaz files into"
    Click the button to the right of this field and navigate to C:\tools\Topaz_Tools\lib\Book
    This folder you have to choose as "Directory you Extacted Topaz files into".

    Now we are back to our "TopazFiles2SVG.pyw" window.
    Click "Start". Wait. After you see "Processing Complete", click "Quit".

    7) Run(double click) this file:
    C:\tools\Topaz_Tools\TopazFiles2HTML.pyw

    You will see a window with this input field "Directory you Extacted Topaz files into"
    Click the button to the right of this field and navigate to C:\tools\Topaz_Tools\lib\Book
    This folder you have to choose as "Directory you Extacted Topaz files into".

    Now we are back to our "TopazFiles2HTML.pyw" window.
    Click "Start". Wait. After you see "Processing Complete", click "Quit".

    9) Mission accomplished.
    Open "My computer" and go to C:\tools\Topaz_Tools\lib\Book

    To see your book in html, open the file "book.html"

    To see your book in original version go to:
    C:\tools\Topaz_Tools\lib\Book\svg

    Then open this file "page0000.xhtml" (page navigation also works).

    P.S. Also if you want to see more detailed information about conversion options read this:
    C:\tools\Topaz_Tools\lib\topaz-readme.txt

  152. Bradley,

    First of all, you should NOT install the latest version of "Kindle For PC", because our files won't work with this version.
    For exapmle I have "Kindle For PC 1.0.1 Beta 1" and everything works, so you should find this version somewhere:
    http://www.google.com/search?q=Kindle+For+PC+1.0.1+Beta+1

    After you install this version, download this file:
    http://www.mediafire.com/?zmgwbcmmjxn

    Unzip it to Desktop.
    Open "Kindle For PC", navigate to "Home" to see all your books, then close "Kindle For PC".

    Download and install this(it is needed to run the files you unzipped):
    http://www.python.org/ftp/python/2.6.5/python-2.6.5.msi

    Go to Desktop and run(double click) unswindle.py
    "Kindle For PC" will be opened automatically.
    Double click the book you want to get and after the book is opened, wait for a couple of seconds.
    Navigate back to "Home"(to see all books) and close "Kindle For PC".
    File dialog will be opened.
    Enter the file name for your book and choose where you want to save it.
    A couple of seconds later you will have a mobi file with your book.

    Download and install any of these programs to view your file:

    Mobireader

  153. In my previous post I described a way to decrypt mobi book in the old version of KindleForPC using unswindle.py and MobiDeDrm.py.
    For those of you, who installed the latest version of "Kindle For PC" and can't use unswindle.py and MobiDeDrm.py, there is a way to get your mobi book without using unswindle.py and MobiDeDrm.py.

    To do this you will have to use skindle.

    Download this file:
    http://www.mediafire.com/?mn3vmttbwrt

    Unzip this file to your C hard drive (after this step you will have "C:\tools" folder)

    Open "My computer" and go to C:\tools\Kindle_Mobi_Tools\skindle-06
    Leave this window opened and don't do anything with it yet.

    Now you will have to locate your "My Kindle Content" folder.

    For example on Windows 7 this folder is located here:
    C:\Users\YOUR_USER_NAME\Documents\My Kindle Content

    On Windows XP here:
    C:\Documents and Settings\YOUR_USER_NAME\My Documents\My Kindle Content

    Replace "YOUR_USER_NAME" with your user name.
    This folder is also easy to find on Vista(I don't have access to Vista to say exactly where this folder is).

    Find this folder and open it.
    Now you should have 2 windows opened:
    "My Kindle Content" folder and "C:\tools\Kindle_Mobi_Tools\skindle-06" folder.

    Now copy all the contents of the skindle-06 folder(20 files) into your "My Kindle Content" folder.

    Go to "Start Menu", find Command Prompt and launch it.
    Command Prompt looks like this:
    http://ashwinkunkolienkar.files.wordpress.com/2008/05/dos-command-prompt1.gif

    Now in "My Kindle Content" folder you have to choose the book you want to get.
    It will have a name similar to this one: "B0RP2EET2_EBOK.prc"

    The easiest way to locate the book you need is this:
    Open "Kindle For PC", remove all books from your "Home" tab, go to "Archived Items" and download ("Add to home") the book you want to decrypt.
    It will be better(for complete beginners) if you download ONLY the book you want to get, because it will be easier to locate this book.
    So you should better have ONLY this book in the "Home" tab in "Kindle For PC" and all other books should be deleted (i.e. should be moved to "Archived Items").

  154. Now, you should launch Command Prompt.

    In Command Prompt you will have to execute a command, similar to the following one:

    cd "C:\Users\YOUR_USER_NAME\Documents\My Kindle Content"

    Note: In this line you should replace "C:\Users\YOUR_USER_NAME\Documents\My Kindle Content" with path to your "My Kindle Content" folder.
    For example your user name is Anna and you use Windows 7, so you should construct the following command and then copy it:

    cd "C:\Users\Anna\Documents\My Kindle Content"

    Paste the line you constructed to Command Prompt(click little icon in the upper-left corner of the Command Prompt window, then click "Edit", then "Paste", then press Enter to execute command):

    Next, in Command Prompt you will have to execute a command, similar to the following one:

    skindle.exe -i B0RP2EET2_EBOK.prc -o book.mobi

    Note: In this line you should replace B0RP2EET2_EBOK.prc with the full name of the file you want to get (from "My Kindle Content" folder).
    Also you should replace "book" in book.mobi with the name for decrypted book.

    For example you want to decrypt the file Vsd44_EBOK.prc and you want to save it with the name mynewbook, here is the line you should construct:

    skindle.exe -i Vsd44_EBOK.prc -o mynewbook.mobi

    Paste the line you constructed to Command Prompt(click little icon in the upper-left corner of the Command Prompt window, then click "Edit", then "Paste", then press Enter to execute command):

    Now if all goes well, you will have your decrypted book named "mynewbook.mobi" in your "My Kindle Content" folder.

    Download and install any of these programs to view your mobi file:

    Mobireader
    http://www.mobipocket.com/en/DownloadSoft/ProductDetailsReader.asp

    FBReader
    http://www.fbreader.org/win32/

    P.S. Also if you want to see more detailed information about skindle.exe options, read this:

  157. Does anyone have any suggestions for running all of this through wine on a 64-bit system (ubuntu 10.4). I installed ActivePython 2.6 under wine as suggested by Dave:

    "Oh, and FYI, I'm running Kindle for PC under Wine in Linux, and using Activestate python for windows installed under wine as well. Your scripts work just fine (wine python unswindle.pyw)."

    I run the command and get the following error:

    ubunt@ubuntu:~/My eBooks$ wine python unswindle-v6-rc1.py
    Trying to load PE image for unsupported architecture (AMD-64)
    err:process:create_process starting 64-bit process L"C:\\Python26\\python.exe" not supported on this platform
    wine: Bad EXE format for C:\Python26\python.exe

    wine and python are AMD64. Is unswindle only 32-bit?

  160. I haven't gotten it to work yet, but I still appreciate all your effort and the contribution you've made.

    I'm running into an error early in the script. I searched the comments in this post and read through a quite a few, but couldn't find anything similar to this or this early in the script. The error is:

    File "C:\scripts\unswindlev6.py", line 106
    DBG_CONTINUE = 0x00010002L
    ^
    SyntaxError: invalid syntax

    (The caret '^' appears under the L in a monospaced font)

    I'm running v6-rc1 in a command window with Administrator privileges on Windows 7 64-bit.

    I am using Python 3.1, 32-bit version.

    Thanks for any help.

  161. I get the same error but at line 100 with version 5 of the script.

  162. I uninstalled Python 3.1 and installed 2.6.5, which eliminated that error. But now I get the "Unsupported version of Kindle For PC error. My kindle version is 1.1.0 (30136). Looking to see if I can uninstall and reinstall an earlier version.

  166. Its been quite a while since any updates. Are you planing on taking on the new version of Kindle?

  167. Tried using unswindle. Getting "error: failed to determine book path." I'm new at this. Running on WinXP 6.0, using K4PC beta. Can someone offer ne advice?

    ReplyDelete
  168. Super new version of K4PC out, July 4th version...

  169. Whoops, I mean July 6th version...

  170. @flashkid Are you certain? Downloading still gives me the same version I got last week. Does it work with unswindle v7?

    ReplyDelete
  171. @cabbage:
    Not sure it it is compatible with V7, because when I try to run it on the updated version of K4PC I have unswindle says "Incompatible version".

    Here's the screenshot of my About dialog...

  172. I went to Amazon and downloaded the newest version of K4PC and used v7 of Unswindle and it worked perfectly on a new Kindle Mobi.


    Thanks i♥cabbages,

  173. @flashkid Huh, that is odd, esp with stewball reporting success w/ a just-downloaded K4PC. Do you still have the installer EXE kicking around? And if so, could you e-mail it to me at i.u2665.cabbages@gmail.com?

    ReplyDelete
  174. Latest version is 1.1.1.30156

  177. Ian, I had the same problem. Looks like the built-in updater still has the previous version. I downloaded the latest installer from amazon.com and it works fine.

    I had K4PC already installed on my computer with a version that worked with the previous version of unswindle. I then let K4PC update itself. The version it gave me (the same version you got) is not the latest. The latest is available on amazon.

  181. I have Python 2.6.5 x64, unswindle 6, mobidedrm 0.14, and Amazon Kindle for PC 1.0.1 Beta 1 installed.

    unswindle 6 and mobidedrm are in the same directory.

    When I double-click unswindle.pyw, nothing happens. No console opens. No processes instantiate. Nothing.

    Last week, this worked. The Python script would launch Amazon Kindle for PC. I have not updated, installed, or uninstalled anything on this PC. I have not even copied any files or directories.

    I am running Ms Windows Server 2008 R2 Standard. I am Administrator. I do not need elevated privileges like in Ms Windows 7.

    Why does nothing happen?

    ReplyDelete
  182. I allowed Amazon Kindle for PC to update itself to the latest version, 1.1.0. I also updated to unswindle 7.

    No change in behavior. As before, when I double-click unwindle.pyw, nothing happens.

  184. I tried uninstalling and reinstalling everything based on both Amazon Kindle for PC 1.0.1 Beta 1 and 1.1.0 with both unswindle 6 and 7. This included cleaning up the directories and files left behind by Amazon Kindle for PC every time.

    No change in behavior. As before, when I double-click unwindle.pyw, nothing happens.

  185. Ok, the can't find the book path problem seems to resolve if you are using the 1.0.1 beta version. As soon as you download it and install it, go the menu and uncheck the updates box. Then you have remove from the device all the books that were added when you had the newer version installed. If you don't redownload them from your archives, you will get errors. If you do you won't. If your books is in Topaz....oh, well

  186. I installed unswindle 7 in my Python26 file, which also contains mobidedrm. I am running Windows 7, and Version 1.1.1 of K4PC. I get the following error message:

    Traceback (most recent call last):
    File "C:\Python26\unswindle.pyw", line 851, in gui_maininpath, pid = unswindler.get_book ()

    You have been so helpful to me in the past with inept, I really appreciate it. I am currently using skindle, but your UI sounds better. I am going to retry installing all of this as administrator, and see if that makes a difference. I will post if it does.

    Thanks, Debra

  187. Big thanks - works perfectly. Kindle content on the iLiad - just like it should be.

    Combination:

    XP SP3
    Python 2.6.5
    Unswindle v.7
    mobidedrm taken from tools_v1.7

    Everything in the c:\python26 folder

    K4PC v1.1.1 released July 21

    Went without a hitch....thanks again.
