    Default Can't write flash or eprom in A3 8P BMM using KTAG

    Hi,
    I Can't write flash or eprom in A3 8P BMM using KTAG. Yesterday i wrote flash with ktag using flash dump that i made using kess by obd2. Now i can't write anything to ecu by ktag. When i try i get peration not allowed. I can only read both eeprom and flash. Is there any way i can write it?

    Because you wrote a obd file with BDM. Now your ECU is bricked, you now need to checksum and write it back again with KTAG. Hope you have a BDM read from your ECU before you write ...
    Eight bytes walk into a bar. The bartender asks, “Can I get you anything?”
    “Yes,” reply the bytes. “Make us a double.”
