ipad 4 shutting down or restarting every 3 minutes
so i have this ipad 4 and the problem is, at first it died from overuse, drained battery, i decided to try and shock the battery with a power supply and it powered on, but the problem is, i accidentally broke the flex that connects to the main board and the gsm or cdma board. but the ipad still powers on but it restarts or shutdown every 3 minutes. i ordered battery online and tried replacing the battery but still the same. it restarts and most of the times, shutdowns on 3 minutes. could the broken flex be the one that was causing the shutdown or restarting?
