Not turning on after screen replacement
Hi i used to repair iphone 4s and this time something went wrong and i dont know what really happen.
I change a broken screen and turn on the phone not putting everything back just to test, and it works. then put back some of the stuff back on and tried and it worked again. then assemble most of the thing and turn it back one And this time it didnt work.
It wont turn on. Could you please help me?
Thanks a lot
Is this a good question?
