Dead iPhone screen after trying to fix home and power button
Hi all. I tried to fix an iPhone 3G affected by the following problems: home and power button don't work, broken screen glass (but LCD still worked great).
At first I disassembled the Iphone (following the iFix's step-by-step guide), getting off the LCD screen and the glass. Then I did the same with the logic board. Finally I noted that the flex circuit was almost cut, near the power button, so I decided to reassembly the phone as there's no solution to fix this without a new flex circuit. During the reassembling I noted a small piece of metal connected to the logic board, in proximity of the label "do not remove", here it is (circled in red):
I don't know what it is (and I found nothing about it on the Internet) so I repositioned it as better as I could.
When reassembled all the parts, the screen didn't work anymore, in any case.
I don't know what to do. Is the position of that piece of metal I showed you? Or the iPhone is simply turned off and it needs to have the power circuit changed? Or something else?
Thank you in advance
