Device: kindle dxg
Have connection

Hi havhill thank you very much for advice. I did change baud to 115200 and 8N1. It is connected, but In my case (Kindle dxg) connection was different than in ebs version.
1. 5V from converter (where 1 on the board)
2. Rx port.
3. Tx port.
4. Ground.

Kindle has 3 choices while boot.
1. If pressed home Reset mode where you can copy the files to memory where nothing I can see.
2. If press enter you will have Developers choices:

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

And uboot.
In my case the framework is not starting.
I am beginner in linux and I think did very bad mistake.
When I changed browser configs I used mntroot r command I don't know why. than turned debug off and restarted. after that kindle never started normally.

Can I make mntroot rw command in uboot???
How can I fix please help or at least advise. Can I reinstall firmware?
Thank you very much.

Good that you have it working to this point, though.
I think the root file system is corrupted (due to not properly unmounting or re-mounting it read-only).
The way to go is
- you've got to get yourself a partition image of /dev/mmcblk0p1 (first partition on the flash disk), maybe a kind soul can provide it to you,
- you've got to dump it to the first partition of your device's flash disk.

When doing the latter (via option 3), you will find that there's a passwort that needs to be entered. I'm not sure, but I think you need to recover it from the Serial No of your Kindle. Maybe others can comment on this.

The whole procedure is showed in a video that seaniko7 made: http://www.mobileread.com/forums/sho...d.php?t=134637
The mkfs is not needed, since you're dumping a full partition image anyway. The hardest part will probably be to find out the password for your device.

In the recovery menu, do NOT chose 4 (Erase MMC0) and probably not the format option either.

I'm not sure about books and stuff. I think you will probably need a (live CD/usb stick?) Linux, although you probably can dump partition images on windows, too. Someone with expertise in that regard might jump in here...

The following script works on my kindle 3w and 3g for root password, (and on my DX and DXG):
---
#!/bin/bash
serno=$1
echo kindle root passwd:
echo fiona$(echo $serno | md5sum | cut -b 8-10)
---
It adds 3 hex digits to fiona password. The Sir Alex's KDT adds 4 hex digits, which do not work as a root password for my kindles. You can convert the 4 hex digits to 3 hex digits by removing the last digit from what KDT reports.

Although the 3 hex digit fiona password works on my kindles for both SSH and for the "login" command (and matches what "John the Ripper" finds when I crack my passwd/shadow files), I do not know whether I will need the 3 or 4 hex digit fiona password for serial port diagnostic root access).
