In the end, this works.
I enabled root access on my LDPlayer 9 instance, installed K4A 4.17.0.146, copied the
map_data_storage.db and imported it into DeDRM, then updated to K4A 8.53.0.100, copied the downloaded KFX files to my PC, and imported them into calibre.
The DRM was removed.
Even Kindle eBooks released after April 22, 2025, work without any issues—that's all.
I don’t understand why nobody else thought of such a simple idea.
I don’t have any Kindle eBooks with the "super-strong" KFX DRM, so I can’t comment to that.
