My friend’s mom slammed my friend’s phone on the ground because she got mad, and she gave it to me to fix. I opened it and reconnected the battery and lcd connections, but nothing happened when trying to turn on. It also isn’t recognized by iTunes, while my other iPhone is by the same cord. Any help is appreciated!!! P.S. - The screen isn’t cracked at all
There’s a good chance that the logic board was damaged. It could be a cracked solder ball underneath an IC or a damaged or dislodged component that is causing boot issues. If that’s the case, there’s not much you can do from a DIY perspective and will require a micro-soldering repair. I would open it up, check all the connections, look for visible damage on the board and also inspect the flexes for small tears. You may get lucky.
