need help in restoring kindle3

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.

howto example:
dd if=/dev/mmcblk0p1 of=/mnt/us/rootfsbackup.bin bs=1024

mailto: yandoogle@gmail.com.
Thank you very much for your attention!

I tried to get to the rootfs, but I can't see the Kindle on the PC when I'm in the Recovery menu. When entering "Export to USB" (press u in the developer menu), I just can see the ordinary folders, no real file system. I think that just fat32 partition is mounted. How can I mount all partitions in Linux? Do i have to initialize the partitions first?

To export the entire mmс0 you need to connect the device via RS232, and then when you start select the menu item 3 "export mmc0". But for this will require a password, which is always "fionaXXXX", where XXXX is computed by the device serial number.

I can calculate this password for the device serial number using a debugger.

To get the device ssh console via wifi use this links:

I don't have an RS232 cable, but I will try it via usbnetwork. Never done such thing before, but maybe I will manage it.

I did a backup as soon as I got my k3 using
dd if=/dev/sdb of=/place/to/backup/k3.orig.img

but I am afraid the img file is too large in size to deliver.

Thank you!
fs copy size should be somewhere 230 MB.
You can send it on ftp.filekeeper.org.
login I posted in personal mail.
If you have any questions, please!

In fact the raw data size backuped is somewhat 4 Giga bytes, I am afraid it is not possible to deliver it via ftp.

in linux you can mount backup raw file to any directory and remove directories with the personal files /mnt/us, /mnt-base.

example:
Quote:
mount -o loop /tmp/backup.img /mnt/any_dir
rm -rf /mnt/any_dir/mnt/us /mnt/any_dir/mnt-base
tar -cvzf backup.tgz /mnt/any_dir
As a result, the size of the backup.tgz archive will be ~200 Mb

Hi,

I'm trying to create my own backup image. I ran the command:

Code:
dd if=/dev/sdb of=/mnt/us/backup.img
over PuTTY, but it just said

Code:
dd: can't open '/dev/sdb': No such file or directory
What would be the input file?

Code:
fdisk -l
displays nothing
