User’s question: I am trying to write the original VR with ECUHELP KT200, read file that is 100% identical to the Bench read file (flash area). Could be IMMO block writing in OBD
the problem was that the computer should be in the car, if not in the car, the success rate will be low, it will fail to unlock.
ecu already reprogrammed 2 times can be blocked, or bad file or checksum, the best way to do it is ecu it’s in bench mode as you are sure of your reading, and your tprot.
