See
https://www.amazon.com/gp/help/custo...MQC26VQQMM8XSW
Version 3.4.3 gives kf8 (azw3). Never KFX
Versions 5.6.x and later give KFX mostly.
If the ebook is ancient it might be mobi or azw (mobi with different encryption)
So that leaves
Kindle Touch (4th Generation) 5.3.7.3
Kindle (4th and 5th Generation) Latest version: 4.1.4
The original K3 and some others got azw3/KF8 by pack port on firmware. Originally mobi/azw. K3 upgrades to 3.4.3.
The K1, K2, DX and DXG apparently didn't have enough RAM to backport kf8/azw3, so don't do it.
