It was needed just to overwrite rootfs with the dump (using "dd").

All like described here:

also you can ask anyone with same model to do the image for you with just simple script

Spoiler:

#!/bin/sh

# diff OTA patch script

return 0

packed into update.bin package with KindleTool (taken from this forum)
NB: jailbreak installed is needed!

p.s. seems it was possible to do the restore even without disassembling kindle and serial console, just packing rootfs.tar.gz into restore package..
(didn't test this)

Thanks for all advices!
