- in system diags menu export USB storage (menu "U) USB device mode")
- mount USB storage, copy system partition backup file to it and correctly unmount
- quit USB storage mode (menu "Q ~ to continue")
- get login prompy (menu "D) Exit, Reboot or Disable Diags" and then "L) Exit to login prompt")
- login as root (default password can be calculated but you may as well update your backup to alter it prior fastboot flash)
- flash system partition (dd if=/mnt/base-us/mmcblk0p1.bin of=/dev/mmcblk0p1 bs=16384)
- reboot
I'll try to write some step in more detail on wiki, including "screenshots" of individual menus. |
Hmm, "bist". I'm curious if that's the thing that made it work. I know it's asking too much, but if someone will try to flash diags without first going to "bist" mode and then with and see if it didn't work before and worked afterwards.
