Iphone 6, no known water damage, came in dead

replaced Tristar

short on VCC_MAIN found on C3221_RF, replaced from donor board

phone boots, everything works fine but no service. SIM is recognized, *#06# shows IMEI, gps wifi bt all works

reballed BB_CPU with short jumper on V1 and long jumper on U1 no change on the issue

replaced dock and all antennas, still no change.

Yeah at that point I would set it on fire too. Could be anything stupid in the RF circuitry. Was tristar really dead or was it just C3221 shorted?

I think it was just the capacitor to be honest with you. But it was drawing 0.060 amps from the charger so I went for the tristar straight away. This thing gave me a headache. I was sure to solve with the jumpers on the bbcpu but nope. What bothers me is that I can see the IMEI, SIM service provider and everything. Just it won't ever connect to the network

IMEI is present so it is much more likely a RF problem than BB CPU stuff. Check antenna connectors and caps/coils in the RF section, I bet something got knocked off or damaged.
