Hello mates,

Have a strange problem with the car. ECU readed in boot mode with galletto v54 clone. MED17.5 (Infeon TC1766). Read all internal flash and eeprom and write also the same.
Program said nothing about during reading TPROT and during writing everything was ok. Car started drives ok, but when I turned the ignition off car won't start anymore and a lot of DTC on the dashboard (ESP, ABS and so on).

Maybe someone has similar problem or can say what's wrong?

Thanks everybody

Which file you wrote in ECU? Only flash modded?

I wrote in ECU file with eeprom. But made changes only in flash. EEPROM has 0 changes.

Write full ori backup. And then write only flash modded. If the tool ask you for checksum correction, consent it.

Mate, do I have to make some movements with this TPROT? Or if there is no error just write and that's all?

No problem for tprot. Write only flash!

Reporting. Everything ok. Your advice helped me a lot.

Good! Your tool doesn't correct checksum during writing full backup. During writing only flash, yes...
