Wifi ic/module getting really hot after drop
Hi, I really need some help with my Iphone 6 mainboard. After a drop on the floor, the display got damaged and I replaced it. Right after turning the iPhone back on, I noticed that the backside beneath the camera is getting a little too warm. I tested the Wifi and found out, that it doesn't show any networks even though it should. So I took a closer look at the ic itself: As soon as I connect the battery, the modul heats up and after 10 seconds it is so hot, that it hurts touching it. I tried to reflow the chip using a heatgun with a 600° celcius setting for about 30 seconds with aluminum foil protecting the other parts with no luck, it still does not work the way it should. I can use the iPhone until it tells me that the it needs to cool down and I am only able to make emergency calls.
So this is what I think: somewhere around the chip or the chip itself must create some kind of short or bad connection, because even if I dont turn on the iPhone (I tried to connect only the battery once, with the same result) the ic starts heating up(airplane mode does not help either).
Is there anything else I can do?
(The iPhone is this under warranty)
