922.7 7g failure c426 start enable drive authorization system not issued

[nano2017]

Yes only star diagnosis and mercedes cgdi device.
I am very angry to myself that i am so stupid and made the software updates with offline flashing.
And now i run into big trouble with this car only by flashing engine ecu und central gateway.
They are flashed succesfully but the car does not function properly and sometimes will not crank....

Update: For the flashing process i took a cloned used engine ecu me9.7.
Now t took back the old engine ecu with old software, but the problem is the same with the 922.7 gearbox.
I think the last option is to buy a used cgw with same partnumber and old software and teach in with star diagnosis copying the data from old cgw to new used cgw....
