phone wont power up with new screen
i got an iphone 4 on att. when i attach a new screen, it will not boot up. no light, no picture. If i put back the old screen, everything show up. If i let the phone boot up with the old screen, then switch the screen, then picture and touch works.
The iphone 4 is on ios 5.1.1. Would the ios have anything to do with this issue?
I dont want to update the phone's ios, because its not my phone.
Also, i tested the screen on an iphone 4s and it boots up fine.
Ist dies eine gute Frage?
