My iPhone 8 randomly shut down and now won’t leave recovery mode every time I try to restore it. The phone disconnects from the pc right when the restore part is startin.g It’s not a cable issue as I’ve tried many and also have tried 2 different computers. I tried 3 different software versions as well as itunes and 3utools for flashing. Something about the restore part triggers the phone to disconnect. Is this some sort of hardware issue or am I out of luck?
If the phone randomly shut down before all of these attempted Restore’s, then I think it’s safe to say that there is likely a hardware issue that has to be resolved first. There must be an issue in one of the subsystems that is causing the boot process to fail. You could start with a bare board approach, keeping the strict minimum such as a charge port and a battery. Connect it to your computer and see if 3uTools can recognize it. If it isn’t stable in this condition, then you almost certainly have a logic board issue. If it does boot, then add one module at a time until you figure out the what is causing the issue. As for a logic board problem, it will need to be looked at by an experienced micro-solderer. Is there any background info you haven’t mentioned like drops, previous repairs or contact with water?
