I have this car with engine 1.2l 16v petrol with ECU Magnet Mareli IAW 5NR.CE1. I wont to make immo off i  desoldered the chip 2904v and through my only programmer that I have xp400pro read with ST/ST95160/  After that, I did immo off with ECU VONIX, but when i return the file with the modified eprom, nothing happens, because i have the feeling that the xp400pro does not write back the file and it is not the eeprom that was repaired even though it says that it was successfully written.

This is eprom which  read and it is also a modified file with the ECU VONIX. Can you help me and check files?

chip 2904v it is not a memory chip
xp400 you can also check if it is written well / just read the user manual
