  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.
