After replacement of WiFi/Bluetooth antenna still doesn’t work (WiFi grayed out,no Bluetooth) . . but iPhone won’t power on off battery but will if Charging . . . Won’t power boot . . . Then starts trying but just repeats showing the apple logo. Can’t turn off. Please help. I’m trying today to plug into iTunes and try a restore. I have to go inside the iPhone and unplug the battery connector to get it to stop flashing the Apple logo. It seemed the repair went well . . I put everything back the same as I took things out. When plugged in I can get home screen and saw the the battery is in perfect health 94%
Greyed out WiFi is normally not a part swap issue. Greyed out WiFi is due to the ic it self being damage or shorted resulting in phone getting hot and shutting down. The WiFi ic on this model is paired to the Memory IC called Nand they will both need to be removed and Nand will need to be unpared . Board level repair will be needed although cost might outway the repair.
