Thanks for the advice, but I've tried this before, unpacked several firmware versions, but I didn't find the main_kernel.img and mmcblk0p1.bin files there.

Specifically, the update_kindle_paperwhite_v2_5.12.2.2.bin firmware is decompressed into the following files:
rootfs.img.gz
rootfs.img.gz.sig
update-payload.dat
update-payload.dat.sig
and the imx60_vario folder

And the firmware update_PW2_5.4.3.2_initial.bin is on:
data.stgz
data.stgz.sig
rootfs.img.gz
rootfs.img.gz.sig
update-J4032-wario-003.dat
update-J4032-wario-003.dat.sig
and the imx60_vario folder

And how to get the main_kernel.img and mmcblk0p1 files.bin I do not know.
