I moved the parts of my iPhone to a new housing since the glass at the back was destroyed. Now, my iPhone is in a boot loop and I tried to put it into DFU mode and plug it to a computer, but iTunes and 3uTools does not see it. I tried to use my USB Tester to see if the iPhone charges and my tester reads 0 Ampere, but when I plug the charger, the iPhone would turn on. I also tried using multiple cables, and also tested the cables on other iPhones. What does this mean and how can I fix it?I didn’t plugged in the NFC / wireless charging coil yet, because the part did not arrive yet. Would this cause the issue?

I already fixed it! I just replaced the lightning cable connector (the long connector on top of the battery connector). I tried to leave the NFC / wireless charging coil unplugged while testing it and it boots up!
