Simos PCR 2.1 Kess unlock

[bugarcek]

Hi

I have some wird question

Maybe someone have original kess...
And tried to write mod file with obd. Kess unlock ecu. Did someone tried to read modded file and than compare with mod before write. What is changed except cheksumm?

If we know the algoritm there will be possibility to write file via obd without eeprom unlock with clone tools... At bosch ecus ther eis jo problem to find VR file, sometimes just sgo convert to bin is enough.

when you read it with kess you will not get a full file... try to read...
and open it under winols for example... and you will see a lot of FF...
with kess you are not able to read whole flash only a part of them...

a VR from Alientech or with ODIS E you´ll get a full file... Suitable for write...

even when you read it with ktag with new protocol (I think 994, but not sure 100%) you will even not get full read...
