The black line indicates where the aluminum frame was before it came to my possession. Okay, so this phone basically boots up normally (sometimes) but then all of a sudden it reboots. And it does it constantly. The phone was bent on the topside, about 30 degrees or so, could that have caused damage to the motherboard that is causing the booting? I bought a new screen, and reconnected screen cables, i think one of the ports was a bit loose, but down know. Any ideas?

Can you take a picture of where it’s bent? Between the battery and the sim tray is just about where the main processor (The CPU) is. If the bend spot is right there then there will be a weak connection between the logic board and the processor which would explain the random shut downs.
