that is a hardware problem! try to reheat first the cobba before changing it! after reheating and the problem is still exist then that is the time you have to replace a good cobba.

you have already change the cobba and it still doesnt work? well maybe the cobba you replace is still defective. try to get a good cobba on a working unit. after replacing the cobba and it is now working then use noktool18 to to unlock and calculate faid.
