Sorry for my bad English.
My name is Vladimir. I am from Russia.
Can anyone help me restore my Kindle 3 wifi.
The study of the device led to its failure, deleted partition mmcblk0. Now I was able to export mmc0 in recovery mode. But I need a copy of the file system, of course without any directories with the personal files: /mnt/us, /mnt-base and /opt/amazon/ebook/config/reginfo.
dd if=/dev/mmcblk0p1 of=/mnt/us/rootfsbackup.bin bs=1024
Thank you very much for your attention!
