Bricked stora ms2100 -- need help (3 replies)

Hi,
forgive me if I'm not very precise as I'm newbee in Uboot and embedded linux
My STORA with stock FW had broblem lately with flashing blu led and no connection. I've setup a serial connection to check what was wrong. I got NAND error PEB & LEB that prevented the UBIFS to be mounted to set and load /newroot. I got access to basic Linux system through serial connection in putty.

I then tried to boot from usb following the indication found in "https://github.com/evgkirov/stora-debian-install" and I have modified the uboot env variables accordingly.

The new booting process started ok but ended with a crc error. Below the log I got.

tried to set the uboot env variables back to the original to come back to the previous stage as I wanted to try another way. No success as the new booting was stopping with a Marvell >> prompt.

I looked into the Uboot command help and I found the command "resetenv" saying "Return all environment variable to default.". So I executed it and then gave a reset.

Marvell>> resetenv

Erase Env parameters offset 0xa0000... done
Warning: Default Environment Variables will take effect Only after RESET 
Marvell>> reset

The printenv command repleys with a lot of "ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ" characters on the screen and "Environment size: 131069/131068 bytes" at the end.

I try to restore the old env variable one by one (I have the output of the original "printenv results") but set env seems not to work. Below an example:

Marvell>> setenv baudrate=115200
Marvell>> saveenv
Saving Environment to NAND...
Erasing Nand...Writing to Nand... done
Marvell>> printenv baudrate
## Error: "baudrate" not defined

I've read a recovery procedures but I'm confused on what to do to recover my Stora.

Can you please help me ?

Thanks
Regards
