help install u-boot on lenovo ix2-ng

my storage is broken
I accidentally overwritten the bootloader and looking for a recovery method
help who can

ruspray,

Download the Lenovo u-boot backup file mtd0.bin from this post:

https://forum.doozan.com/read.php?3,19216,38354#msg-38354

And connect serial console, using UART booting method:

Once you can boot with kwboot as described, it is unrbicked!

root@debian:/home/ruspray# kwboot -t /dev/ttyUSB0 -b mtd0.backup -p
Sending boot message. Please reboot the target...-^C

this is what I see now

ruspray,


1. Check the serial connection on both ends. Has this serial console converter ever been connected to the Lenovo and working before?

2. If you run minicom or picocom (instead of kwboot) with serial console what do you see? any output at all?

Yes exactly

ruspray,

If kwboot does not work then the only way that you might be able to unbrick it is using JTAG. Look for JTAG interface on this board.

No, not needed.

kwboot will only work if we can find UART0 connection somewhere on the IX2 circuit board. Look at forum discussion "No serial output from kernel on Iomega ix2-dl(ng)" for a possible way to restore these devices. At yet, this method is untested.

Anybody can restore device? I have same state of IX2-NG after find bad blocks on NAND and type nand scrub.
Trying kwboot not help me. IX2-ng not response. May be trying JTAG? Anybody know how to use JTAG?

MaxHoga,

Look in the Wiki thread:
