If you are just having reception/antenna issues then check out the antenna that is on the back of the logic board near the top. It snaps on at three spots, pretty sure one of those spots is wifi and the others are something else—you could look it up on the schematic. See if it is loose.[br] [br] somewhere on my youtube channel i fixed a low signal wifi issue on iphone 6 by resoldering a torn connection on that antenna.
