CGDI add key to BDC error

[laso]

Today, when I added the CGDI key to the BDC in the BMW F15 I received an error. Everything was fine until the flash verification. Then I received an error. I can't do anything more. The car is known to not start now. I did it on bench using the platform. Will you upload the original eeprom now and the car will start? Program ecu with a special file? Now after connecting it screams that ecu is not supported.
Please help

Write back original file and must start


Today I saw 2 threads about problems with F series BMW


I have good tool for them but I always refuse to program additional key if must take out the FEM no worth the risk

BMW dealers sell keys for around £300
