As for actually fixing this, I'd reinstall the firmware from scratch. Assuming there's no issues with the eMMC storage, you should be able to enter the recovery menu by pressing [Enter] at the prompt after the kernel boots. You'll get a menu similar to this:

Code:

Menu
====
3. Load MMC over USB storage
E. Export FAT partition
U. Update using update*.bin file on FAT partition
D. dmesg / kernel printk ring buffer.
Q. quit

Export the FAT partition, load the firmware image to the Kindle then exit the menu and either select the Update using update*.bin file on FAT partition option or reboot the device. Both of these will begin installation of the update.

Finally I bought an USB interface, with FT232RL and I had time to the job.
The interface is with 3,3V and 5V jumper but I disconnect the jumper and I connect the supply pin from an external 1,8V power supply.
It was a little tricky because it was first time when I do this.
Using minicom, I put KINDLE in recovery, and after I transfer the bin file. First time, I got a message that it's not enough space, but I copy and after delete the books and everything was ok.

Many thanks for your help.
