i bought a used ecu mercedes med17.7.5 (the seller told me the ecu ist not original it is a cloned one of his car. the stock data of it no more available)
i tried to clone my ecu to this (used cloned ecu) i can read all data from it and from my original ecu without problem. but when i try to write file to the one i bough it told error unlock password.
i read the password with foxflash (and extract the password too , foxflash can extract from file) but same error when i try to write.

same problem with pcmtuner . can read but not write.


what's wrong and how to resolve the problem.

both ecu are working 100%
