@ proxy_gsm

You need to change your COBBA in the phone ! Proberly theres water/humid damage or solder balls loose under the COBBA. I do not recoomend to just reflow, the fault nearly always come back later at some point. Better just to change it, full flash with virgin Eeprom, rebuild IMEI, unlock, set FAID and do full factory reset.

He's saying set the FAID, which I already wrote, dont see why he should confuse you by saying that ??

I've already written what to do in what order !!
