DeDRM on MacOS Monterey

we need the old Android Kindle apk.

Old Android Kindle apk

• Kindle version 4.16.0.75 for Android
  • install the apk into the device (emulator android 11 is fine also)
  • execute Kindle.app
  • download contents
  • let the emulator developer mode (in my case click 7 times on build number in settings)
  • connect the adb to the device
  • backup like below

  $ adb backup com.amazon.kindle

  • get a file backup.ab

Calibre on Mac

• set kindle key for android by following steps
  • https://github.com/noDRM/DeDRM_tools/blob/master/DeDRM_plugin/DeDRM_Kindle%20for%20Android%20Key_Help.htm
• when u got an error when loading backup.ab
  • get abe.jar from here

  $ java -jar abe.jar unpack backup.ab backup.tar
  0%...100% 
  $ tar xvf backup.tar 
   : 
  x apps/com.amazon.kindle/ef/B0BVM5ZCBR/B0BVM5ZCBR_EBOK.prc: Truncated tar archive
  tar: Error exit delayed from previous errors.
  ^C                                                                       # force to stop
  $ tar cvf backup2.tar apps
  a apps
  a apps/com.amazon.kindle
    :
  $ java -jar ~/Downloads/abe.jar pack backup2.tar backup2.ab 
  ... bytes written to backup2.ab.

  • use backup2.ab instead of backup.ab
