Replaced screen, worked fine, now not and ear piece hot
Replaced the digitizer on an iphone 6, swapped over camera etc etc. Was very careful. Got it all back together besides the plate that covers the connectors and actually putting it back together. Turned it on to test and all was fine. Turned it off put the plate on and clipped it all together. Now won't turn on, be recognised by itunes or charge. The screen side of the speaker ear piece gets very hot when trying to turn on.
I made sure the correct screws were in place so i'm 99% sure it's not long screw damage.
The battery was connected the whole time but i've done it this way before twice and it was ok.
I've tried hard resetting it and had it on charge for an hour.
Please help as it's not my phone, it's a friend from works.
Is this a good question?
