DRM workaround: Kindle for Android

I think it's a Calibre issue. It doesn't happen to me if I limit the adding of books to 3 at a time. More than that and I'm likely to get a .prc. Again, just add that book again and Calibre will accept it in it's proper format.

1. Create a new Nougat VM with the Bluestacks multi-instance manager. (alternatively you can clone your working Kindle 4.16 VM, then skip #2)
2. Follow the instructions in first post to install, login, and backup the Kindle for Android version 4.16.
3. Download Kindle for Android version 8.51.1.0 (oldversion doesn't have it, I used apkpure Kindle for Android version 8.51.1.0 - the arm64-v8a will only work for 64bit Bluestacks and the armeabi-v7a will work for 32bit and 64bit Bluestacks)
4. Install the downloaded APK - if using adb, you need to use "adb install -r XYZ.apk" to update existing app, the builtin APK installer in Bluestacks does that automatically.
5. download and install the AZW6 Image Merge into calibre
6. delete and redownload books that have previously been downloaded with the Kindle 4.16 version, e.g. if you cloned your instance
7. for each book extract the .prc and .ast file (the quick and dirty way is to use "adb pull /sdcard/Android/data/com.amazon.kindle/files" - then traverse the files folder and drag and drop the .prc files into calibre)

This will NOT work on Android Emulator or on a Nexus7 tablet, it probably won't work anywhere else than Bluestacks.

i was so excited to read this, but i just tried and sadly even though i got a prc and ast file, the size does not match what i get from iOS or used to get from comixology API directly. Still the very compressed and unreadable (for comics) ~1200 x 1920. Am i doing something wrong? Would love if you or someone else with this setup could try https://www.amazon.com/Valiant-X-Man.../dp/B072JXR28J. Size should be close to 100 MB which is what i get with my phone in kfx, but i only get 27 MB with Bluestacks 8.51.1.0.

It has been a while. Only tested it for regular novels that come as AZW3 after removing DRM. Not entirely sure what graphic novels come in as or if the ImageMerge plugin even supports them. I didn't write the plugin, just modified it to work for K4A. If I can make some time this weekend, I will play around with the link. It may require the KFX version to be DeDRMed.

I just cloned a VM that already had the low-res versions working, and reinstalled with the newer version of Kindle on Android

Edit: ignore the above. The portal was not supposed to be 5555 in my case.

Absolutely not. Don't ask for any help involving transfers of copyrighted material again. And... not a good idea to share a login!

Perhaps you should take the time to search for and read a few of the older threads about K4PC?

Not to mention that starting your messages with bro is rather silly especially considering the way the meaning of bro changed over the decades. You gotta be sensitive, sistah! Some people don't like being referred to as beer-chugging frat boys in A&F cargo shorts.

Unfortunately the Kindle App doesn't remove the folders after removing the content. As I don't really read the books on Bluestack's Kindle App the following batch script, which I created in my platform-tools folder, works fine:

setlocal
set DLDIR=.\files
set OUTPUTDIR=C:\Users\xxx\Documents\EBookDownload
adb pull /sdcard/Android/data/com.amazon.kindle/files
for /R %DLDIR% %%a in (*.prc) do xcopy "%%a" "%OUTPUTDIR%" /q
rmdir /s/q DLDIR
adb shell rm -r /sdcard/Android/data/com.amazon.kindle/files/B*

The script transfers all .prc files from bluestacks to OUTPUTDIR and cleans up afterwards.

Sorry for typo...
It should be:

rmdir /s/q %DLDIR%
