I also have a problem with a Motorola XT1920-15 : after trying to unlock with SigmaKey (was locked on Tesco UK network) ended with no imei and I have seen that flashing will help but I can't update firmware:

Tryed to flash the firmware from MemoryCard and I get error:

E:footer is wrong

E:Signature verification failed

E:error: 21

also tryed from cmd with commands but I get error on boot and system partitions:
