Hi Today a customer gave me an iPhone 6 which he alledgedly ‘fixed himself’: he changed the LCD Digitizer assembly because it had a huge crack in it. After installing the new assembly and booting it up, following things started going wrong: Wi-Fi and Bluetooth stopped working; Wi-Fi toggle button became grayed-outRear facing camera worked, but couldn’t take pictures. Hitting the big white button in the camera app did not take the picture anymore. Front facing camera worked completely fine.Flashlight does not work anymoreLeaving the phone on stand-by for a couple of minutes will lock you out completely: it won’t power on anymore, and you have to reboot by pressing POWER + HOME simultanously What I tried: Putting a cracked, but working OEM assembly in placeDisconnecting the cameraCleaning the connectorsDisconnecting just about anything but the battery and the LCD / DigitizerSoftware reset to factory defaults None of these things changed anything. I already told him it’s probably a lost cause, but I’m curious what might have caused this. I’ve seen several topics online with people having the exact same issues. Any ideas?
Most of Wi-Fi greyed out problem is due to a broken chip on the motherboard. And most of the problem you listed seem to be a broken flex cable or motherboard chip to… Take a look on motherboard if is there some broken chips.
I have exactly same issues but how can we check any broken chip on motherboard. ???
