Theirs no such problem on the phone itself its just it keeps on restarting sometimes its like happening 2 x a month i need help because i will try to update my phone to ios 11 and im afraid it will not be succesful because of the issue
Boot looping can be caused by many things. Your problem is that it is intermittent in nature. Next time it does it though, I would take note of what happened just before to see if there is any kind of trend. Try these things (next time it happens) to see if anything helps: Try a hard reset (Home & Power button for 10 secs)Use a genuine Apple Lightning connectorUse a genuine Apple charging brick and let it charge overnightTry to connect it to different computers (mac/pc if possible) with an updated iTunesPut the phone in recovery mode (search DFU Mode). Careful, this can reset your data Use 3uTools for putting it in and out of Recovery ModeUse 3uTools to flash the firmware (you can’t downgrade)Check the condition of all the flexes (with magnification)Disconnect the Front Camera Ribbon from the logic board and reboot your phoneDisconnect the screen assembly completely and see if iTunes will recognize the phone. Otherwise, you may have a logic board issue. If you are uncomfortable doing these steps, consider finding a repair shop to do the troubleshooting. A shop that also does micro-soldering can go deeper if the problem is not modular in nature.
