Recently I bought an iPhone 6 Plus 64gb second hand and the phone has a crack glass and doesn't power on by the looks of things the problem is I can charge it or it looks like it's charging and when I connect it to my pc the pc pings but then says it doesn't recognise the device and its also water damaged as the indicator is pink. So in brief short terms black screen,doesn't turn on,seems to charge,pc doesn't recognise connected device. I've searched many sites and I'm wondering if it could be the IC chip that needs ball soldering back and or the c5202_rf chip thing is blown I am baffled any help how to fix would be appreciated. Thanks
