Write ori back and see if car start. Not good idea to do this ecu with clone tool.

I had do this to my Fiorino 1.3 with 8f3 ECU and I had the same problem, with clone kess 1.47 update. I fix the chs with winols and it works great!

Kess calculates CRC.

was the original file rewritten in recovery mode?
