Hi,

Today I read and wrote a tprot patch in bootmode with galletto.
Everything worked fine, the car started and stuff. Then I wanted to flash my modded file into the car with mpps through OBD, and it told me that the checksum is incorrect, eventhough I corrected it in WinOLS. Since I couldn't get arround that message, I accepted it. Then at 100% I got a checksum error and now the car wont start anymore.

I tried to write back the ORI file in recovery mode and at 100% I got the same error.

Is there any chance I can recover this ECU? Gladly I did a backup with my galletto, can I write the 'all' file back in bootmode?

Any response is appreciated, hope you guys can help me.

Thanks in advance.

Propably you used and old protocol to write the file to ecu.

It's normal that you can't recover the ecu,

If you have Kess, use protocol 501 to recover the ecu
