Recovering Kindle Voyage

[hhware]

Hello,

I (with a help of my friend) am trying to recover a Kindle Voyage that is bricked by a software update.
We tried to follow the detailed explanations here:

The instructions are working up to the item 16 ("On the kinle tap 'Exit' and then 'Reboot or Disable Diags', then 'Exit to login prompt'"), because when I run 'bootm 0xE41000', Kindle continues to display the same tree image as before, and the following shows up in the log:

There is no Linux prompt...
If I exit boot_diag by pressing ENTER:

Press [ENTER] for recovery menu...

I get the following

Menu
====
3. Load MMC0 over USB storage
4. Erase MMC0
I. Initialize Partition Table (fdisk) and format FAT
O. Format and overwrite FAT partition
E. Export FAT partition
U. Update using update*.bin file on FAT partition
M. Update using update*.bin file on FAT partition of second MMC port
D. dmesg / kernel printk ring buffer.
Q. quit

If I select the option '3', I get the following:

Unknown option '3'

It seems that everything (uboot, bist) is working up to Linux kernel, but the kernel is not loaded because of MMC errors:

[ 43.932657] mmc_reinit: Error (-110) send op cond
[ 43.937439] mmcreinit_work_func: Resetting MMC, try=3, total_time=20729

The same is happening with 'boot_diag'. However, KIndle is not detected by the PC at all.

I also tried 'bist fastboot', hoping that after entering fastboot Kindle will be detected by PC, but it is not.
One option from 'bist' sound promising:

loadb - load binary file over serial line (kermit mode)

but in order to exercise it, I need to know where to load, what to load and be able to build it for loading.

I would appreciate suggestions on what I could try next.

Thank you!

Unfortunately, everything points to a damaged flash drive. The repair is possible but quite complicated and requires BGA soldering. Execute the "idme" command and write down the serial numbers of the device - this is very important.
