Recover Dead MIB2 High Unit

[car_driver]

Hello guys,

I have a MIB2 High unit for Audi. But due to wrong flash actions it is dead (wrong: flashit -a 54000 -d -v -f /net/mmx/fs/sda0/ifs-root.ifs)
Unit is now booting in Emergency App (red screen), but it not works. It can't read MIB Update from SD Card.
When I access by serial I see only following logs:

Normal mode:

Hi,

Do you have a backup ? Or do you know what FW was on the unit ?

regards

[car_driver]

Firmware was: MHI2_ER_AU57x_P3634 on mib system. (I have this firmware on sd card)

I have a Backup dump from /dev/fs0

desolder RCC flash and rewrite NOR with backup
