I have an iPhone SE 1st gen, I recently tried to do a screen and battery replacement. The first day it was good- then I realized that I had forgot to plug in the camera/light censor. Well I opened it up fine, and then unplugged the battery plugged in all of the screen cables, then lastly the battery connector. I then screwed everything in, and the closed the phone up. Whenever I turned the iPhone SE on, it simply wouldn't charge, I opened it back up and tried EVERYTHING. Still, nothing. I left it on the charge for a while. I came back, it had said that it had restarted. I started to try to use it (on the charge) and then it restared, and then again whenever I tried to use it fore example iMessage. The battery wouldn't charge (even though it said it was) I contacted apple support and they ran a remotely device diagnostic test and they said that the battery results came back n/a! I'm so stumped, I recently bought a new otterbox case that looks amazing on it- Please someone help! I don't know what to do.
