Recovery

Vendor firmware recovery

Prequisitions

To proceed with the recovery procedure the backup with the vendor firmware will be necessary eg. dump.rom.

The backup file should be generated before making any changes in the device flash chip according to documentation in the Reading flash contents section.

Internal flashing

If the platform is booting properly it's possible to recover vendor firmware using flashrom on Ubuntu 20.04. If the flashrom from previous operations is lost somewhere, build it according to this documentation.

To restore the vendor firmware, open a terminal and run the following command:

flashrom -p internal -w dump.rom

External flashing

If the platform isn't booting properly it's possible to recover vendor firmware using external flashing. Follow the Initial deployment section to perform the external flash. Remember, during executed flashrom command use a backup file like dump.rom.
