I tried to write a file to my friends car VW Passat 2.0cr CBAB edc17cp14 through OBD with KESS, it failed and now the car won’t start.
Properly it is Tprot locked.
Before that, I read the original file through OBD, and wrote it back again with no problems.
But now it is properly locked.
Afterwards i have put the ECU to boot mode with kess tricore module, where i have made a “backup file read” and a “normal read”
I have read something about creating a restored file from the three files i just mentioned above.
Hopefully one can guide me in a right direction or help me creating a restored file so the car can start again.
I attach my file

Finally the problem was solved with this guide:
Problem: ECU VAG EDC17CP04/14 blocked writing MOD by OBD (so called EEPROM crash)
caused by: ECU remain in programming mode.
1. Read IROM / XROM and EEPROM in bootloader mode.
2. Fix IROM/XROM using bootloader readout and OBD ORI readout (you will probably need to paste part of map zone and chk/RSA zone)
3. Write fixed IROM/XROM by bootloader (do not touch EEPROM!)
4. connect ECU to the car and write repaired IROM/XROM (same used for bootloader) by OBD.
It will automaticaly fix eeprom problem.
Resolved
