Saying actual counter values would help.

Flash Attempts: 8 Times
Flash Programmed: 6 Times

Kess says "Wrong security code"
KTAG write FULL BDM with complete Restore okey and car start..if I write only Flash file the car doesn't start. I write FULL BDM again from the first file the car works again.

Yes, the "Wrong security code" always appears. Kess EU clone v2.23.

Resolved Counter reset but I still have the same problem...Thought this would solve my problem.

Kess says "Wrong security code"
Galletto through OBD says "ECU locked"

I've never had anything like this before.

I have this one, it's the original I read with OBD at the beginning before locking after few writing in the reworked files.

I have some full BDM form here from forum...but eeprom is not the same so it won't work, right? Can I just insert my eeprom instead of that eeprom and leave the other files? Or I can use IMMO Universal Decoding v3.2 is this software OK for that? Because I have to write everything together, when I write a single Flash file, the car does not want to start (no heater lamp and no turning then). When I write everything together with the first file, the car works again.

p.s. yes as you say make off... I can use IMMO Universal Decoding v3.2 is this software OK for that?
