try write ori file with recovery option on kess, its like normal writing but with very slow speed, i have success with that option sometimes .. try few times, sometime wont work on first attempt..

Or just insert your kess read into your bdm read and flash it back, it’s easy. If you can’t - upload files here, someone will help, 1 minute job.

hi, i didn't know it was possible to writ an obd file through bdm ?

possible to recreate restore file, post here OBD file and BDM file you read AFTER failed obd writing

ecu wont connect now, either bdm or by obd, kess says generic error when i try to id or read, ktag now says unknown ecu, so i just give up on it, i managed to get a matching numbers ecu on the bay for £30, thanks for chiming in jurebv, best of luck to you.
