Hello guys. I just found my old IPhone 4 and booted it up. It worked just fine until I dropped it 15 cm. down on my carpet. Now it can’t hold power. As soon as I put the power cable in it boots up and says that the battery is 100% charged, but if I pull out the cable it dies. The wifi button have also greyed out and cannot be turned on. The phone can’t find any signal either. When I put the phone into my Mac it goes into a form of loop. The apple logo shows, but then it dies again. I have tried to restore it to a clean installation, but the phone could never keep up that long. Any ideas of what is going on?
Honestly I’m wondering if.. The Lightning dock connector just came loose… iPhone 4 Dock Connector Replacement Steps 1-9 could be all you’ll need, if that’s the issue
Battery is probably faulty and Wi-Fi chip has gone bad. Either needs re-flow (temporary fix) or replace Wi-Fi chip.
