How to Restore PCR2.1 ECU if Bricked by OBD?

Make this same procedure unlock but connect ECU on bench, but not bench mode, obd mode. Connect only power cables and CAN cables on bench. Don’t write obd read via bench mode because you final kill this ecu.
With this process you can recover your ecu in same situation.

Or read eeprom bench.. write same eeprom file as you just readed. You will be asked if want to unlock for serial obd programming. Choose YES. After this obd is ok.
