Hi, I was wondering if there is a way to repair the part of the motherboard on Iphone 4 that is responsible for the WIFI (and may be the bluetooth too). There are two “pins” on the top side of the Iphone 4 motherboard, the right one is supposedly the one responsible for WIFI, i have an Iphone that is in perfect condition, but that part is broken. Is it fixable? Thanks. Update i found someone with a wifi problem on ifixit, he assumed it was because of missing screw holes. but he has the same broken “horn” on the motherboard.

Mo Ne, take a look at your complete board. It does not appear as if there are any traces that are interrupted, but it is possible that the component SP1_RF is interrupted. It would help if you have a picture of both sides of your board. SP1_RF is SPRING-UPPER-ANT-N90 and directly involved in your WLAN/BLUETOOTH/FM RADIO circuit. You could try an run a jumper to the component as shown in the schematic. A broken multilayer logic board is never a simple fix. Hope this helps, good luck
Connect the top RF test connector to the top bezel bypasses the contact pad. But greyed out wifi always means dead or loose wifi chip. Bypassing alone would not help
