Phone charges but doesn't stay on
So i recently opened up my phone, according to the guide here, in order to try to put it back together to get the screen to work. (The screen was black but the phone and touch screen all worked as normal.)
Well it worked, the problem is in the process something else go screwed up and now the phone wont stay on unless charging on the wall. It won't connect to or charge on the computer. Is there anything in specific that i could've damage that would cause this? Is there a way to fix it?
