Will not power on, what could it be?
TL;DR iPhone 4 will not power on. Logic board is verified working, battery is verified working and charged, dock assembly is verified working.
So here's the deal, I got this dead iPhone 4 for doing some trade work. I have tested the logic board in my own phone, as well as the battery and the dock connector. I cannot, for the life of me, think of anything else it could be. All of these parts work when they are put in my phone but when I put them back into the dead phone, nothing happens. It doesn't charge, it doesn't turn on, and the computer doesn't see it. What the heck could it be?
