Dear michaaa62,

thanks for the help. I got almost all my most important data back.

I got some further issues though - I tried to reflash my device, but only flashing with the "combined" image worked flawlessly. flashing the emmc with "vanilla" image did not worked, although I tried so-so many ways (ehh, almost every way found on the internet...). after flashing the rootfs is booted normally, but the filesystem returned to read-only mode... when I tried to fsck the /home/user/MyDocs partition it always failed - after running and fixing things for almost 6-8 minutes it froze... so finally I reflashed the rootfs, installed backupmenu (from microSD card) and run it. from backupmenu I run fsck and it worked - after reboot I got almost a 1000 fsck_number_.rec files and everything seems to be working fine now... (I just wanted not only you to know that - I found that some users fail to flash the emmc...).
