DRM workaround: Kindle for Android

I am a bit bummed that the result is a KFX rather than azw3, but converting it to epub via the KFX-input context menu (rather than via Calibre's normal conversion menu) gives a result indistinguishable from how the KFX looks on my phone--though the formatting of the book is a fairly minimal one.

Yeah, I am currently going through my library of books that I had gotten behind on downloading. And since the download to transfer with USB went away, and I got Bluestacks working, I'm getting maybe 1 in 4 that successfully download via 4.16.0.75 (I just attempted 24, and got 6 that actually downloaded). Good to know that the newer one works with the older key in case K4PC stops working for me

Can someone point me towards instruction on how to setup bluestacks (which version of the app, how to setup the program, etc). Thanks.

Did you not see page 1 of this thread/topic?

Yes... though it seems I missed one of the links, sorry about that.
Are the app/program versions still accurate?

Pretty much yes. I did the 64 bit BlueStacks install (5.11.1.1004 P64) and then the K4A 4.16.0.75 install. You will then need to register and export the encryption key. After this, I updated to K4A 8.51.1.0.

It's not the greatest since the K4A app closes itself on occasion but it does work and I prefer the KF8/azw3 files from this method.

The bug where KFX downloads are rejected and KF8 (AZW3) is received instead is specific to BlueStacks Nougat; Pie, on the other hand, should have correctly received KFX.
Also, DeDRM accepts keys even for K4A version 4.17.0.146, even though it's actually a slightly newer version.

Just a quick note. You do need the alpha version of DeDRM. That's the auto-generated version from the latest code. It was last updated in November 2024 (I think).

Thanks, this works for me. By the way I read elsewhere in the thread that you had a batch file to pull the downloads from Bluestacks, is that something you could share?
