Clonning issue - Jagiar / Land Rover BCM HPLA-14F041-BH

I copied the whole content of SPC5746, SPC5747, and 95128 eeprom, from a faulty donnor BCM [1] to a second-hand BCM [2], but after fitting BCM [2] to the car, there is no ignition, and the Pathfinder can't communicate with the car. The BCM [1] is still working in the car (despite its other fault).

I restored the original content of the BCM [2] (I did a backup), but now it doesn't communicate with Pathfinder as it did before.

I also noticed that the BCM [2] (now not working) keeps modifying the content of the SPC5748 SM-FLASH (original or copied from Donnor). It deletes a number of VIN records and changes some other data.

So my question is: Is copying the whole content of the SPC5746, SPC5747, and 95128 eeprom not enough to make a workable clone? Is there something else on the BCM PCB that needs to be modified?
