MobiDeDRM.py - remove DRM from Mobipocket ebooks (unDRM MOBI and PRC files)

[Beginner]

Hi

Okay, as you might get from my name, I am complete dufus when it comes to computers. I've tried to follow your excellent instructions, installing python 2.6, creating a nice little folder c:/python26, and in it, put mobimedrm.py as well as the e-book I am trying to free up.

However, when I try to run the script as you set out, I keep getting the error message that there's no such file or folder as mobimedrm.py.

What am I doing wrong? I have absolutely no idea what I'm doing - all I know is that I'm beyond frustrated that I can no longer read a bunch of books that I have legally purchased simply because the developers have declined to adapt the software for the iphone or ipad.

Thanks in advance for any help you can give me

You need to run the script from the folder where it resides. Use cd command to go to the directory with the script and with your ebook. For example:

c:
cd \ebooks

will allow you to enter the c:\ebooks directory from the command line

Yes, I had done that (instead of moving/copying python scripts to my ebook folder, I had done it the other way around, moving the test ebook to the Python folder).

I found my error, though - the Python extensions were in Python26/Scripts, instead of Python26/Tools/Scripts. So basically, I copied everything everywhere, hoping that the system would find it wherever it needed it!

And... it worked! Thank you, thank you to all you kind people who take the time to put these instructions up.

Let's hope that the remainder of the books work too...

Hello, everyone!

I'm having a bit of a problem here. Is anyone of you having errors removing the DRM from your purchased books after the latest Kindle Software Update? I had no problems cracking the books that I bought before updating to 2.5.2 but had a hard time with the later ones. I think Amazon has decided to change their codes. Do you guys have a workaround for this?

Any book downloaded after 2.5.2, even those bought before and downloaded from Manage Your Kindle, will not work with Mobidedrm.

You can try to downgrade Kindle4PC and re-download your books. Alternatively you can remove DRM using Skindle.

Any idea when MobiDeDRM might be upgraded to handle the 2.5.2 Kindle software release? I too am getting the "no key found maybe the pid is incorrect" error message when I try to run it, no matter which version of MobiDeDRM I try.

Ok, I went back and looked at the beginning of this post.
Are you saying that I have one PID *from Amazon* and another when I import my AZW file into Calibre?
In either case, is it possible to view the PID using Calibre (or some other tool) to verify that I'm using the correct one? I got mine from the website which generates it (http://kindletools.prestonlee.com/).

Just hopping on to this thread. I have a Kindle 2, I use Mac, and I am trying to dedrm my kindle books. I've had my Kindle since November. I just installed Calibre on my Mac and then re downloaded all of my books from Manage Your Kindle.
I imported all of them into the Calibre library. No problem.

Now I would like to dedrm them in to normal mobi format and add those versions to my Calibre library as well. I tried to add the mobidedrm_plugin.py (in a zip) file as an addin, but Calibre did not seem to accept it.
I didn't want to spend too much time on this, and I know scripting fairly well, so I copied all my AZW files into a folder along with the mobidedrm.py file.
I wrote a .sh file with a line for each book in the following format:

python mobidedrm.py "Book.azw" "Book.mobi" 'MYPID'

I used the double quotes around the book names, because they often have spaces.

I got these messages for all of my books:

Extra Data Flags = 2
Error: no key found. maybe the PID is incorrect

I read through all of this thread:

• One messages says to use the V.06 of the script - but that version is not published in the thread :-(
• Then I found this on the last message on the thread.
  

  Any book downloaded after 2.5.2, even those bought before and downloaded from Manage Your Kindle, will not work with Mobidedrm.

• What are you referring to as 2.5.2? Is the DRM version? Does that mean that this script is not working on the latest version of DRM that Amazon has put into place?
• You mention the Skindle tool afterwards, but that is only for PC. Is there an equivalent for Mac?

Thanks for any info.

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