Solution:

Many people have done read obd unlock eeprom write obd without any problem, but you have to do what foxflash software asks to do, such as disconect and connect batter several times.

Just have to be patient and unlocking via OBD takes a long time. everything is ok.

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.

 Here is basic post for people asking basic questions, apparently now on high demand since we have gathered again new members in our ECU group . So you got bosch ecu in hand from car and how to figure out how to identify it and what pinout to use? On this case we can randomly take one bosch ecu that we will identify.

We can see its edc16cp35. Now there are two ways. Either to search in foxflash bmw / edc16cp35 for pinout. Or we head to ecu pinout page and figure out pinout from there. One of the best online pinout catalogs can be found at ecu desing, So save webpage https://ecu.design/ecu-pinout/ Copy address and head out there. Type in edc16cp35, bmw uses two processors in this one mpc 562 and mpc564. Pinouts jus...
