Perfectly intact when I ran over it with my car.. However did not switch on. Plug-in with adaptor cable. Phone did get warm . But apple logo appeared and switched on with screen looking normal. Typed in access code. But went dead in 3 seconds. Was not recognized when plugged in computer at any time. Opened it up and replaced battery. Checked connectors to motherboard are secured. Same behavior. Strangely the battery logo does show up intermittently when put on a wireless charger and phone gets warm with screen showing minor green and purple smudges. Not sure if it is the screen? or something far more serious due to pressure damage on any of the components. Update (08/31/2022)
Thanks, Something weird happened. The apple logo keeps popping up and then disappears again. The battery gets kind of hot. When I take charge cable out it will actually turn on. The battery is low 10% or so and it will immediately pop a message. Then it stays on for 10 or 20 seconds and then back to no power. I can repeat the process. I replaced the battery so that should not be the issue. I also managed to do a restore via i-tunes with hard-boot. So seems it is not entirely dead, but slightly :)
Hi @pronkov Wow ,what can I say! I thought this sort of thing could only be seen is videos that are acted out Now that you have dismantled the phone is the Logic board bent at all?,If it is that’s most likely your issue as a bend on it can cause small chips to rip pads and disconnect, if its not bent I recommend taking all the shields off and checking for any physical damage or loose components If you could upload some photos of everything using this amazing guide that would be a great help Adding images to an existing question Hopefully this helps Any questions please ask Thanks:-)
Sounds like the motherboard might of sustained damage. It’s a sandwich board so will be hard to diagnose without taking it to a specialist repair shop. Other components could also be damaged which could be causing it, charging port, front camera flex, Face ID flex. I’d take it to a shop who would have the parts in stock to change parts out to find the cause of the problem.
