Need Help with my BCM

1
Hello, I have flashed my BCM via SPS with software from another car (same model but different equipment). Unfortunately, the car does not run now. I wanted to flash the old software back onto the control unit. Unfortunately, SPS says that the software on my BCM is too new and the programming process aborts.

The BCM still works perfectly but I need my old software back.

Can anyone help me?
