Chosen Solution
I replaced my screen for an iPhone 8 that was badly damaged and I don’t get anything when I try to power it on. When I connect a lightning cable I just get a boot loop. I have already tried to proximity sensor and disconnected the selfie camera with still no luck. Any ideas?
This will be a battery problem. · Replace the battery. · Check the battery connector on the logic board. · Make sure no components have been nudged around the battery connector. · Try putting some force on the connector when booting.
Check this forum. I know its for and iphone 6 but try these solutions. Phone stuck on apple logo after screen replacement
