Hi Everyone My iphone X was restarting after it had finished downloading IOS 13. I was running out of charge during the process, now, the phone restarted, the apple logo appeared with the progress bar moving for about 10 mm then it restarts and does the same thing over and over. I believe the upgrade was interrupted when the phone’s battery ran out, but I’ve replaced the battery and still got the same. please help!
You will need to put your phone into recovery mode and update with iTunes. Make sure you have the latest version. Remember you need to update not restore or you will lose your data.
Try to update your phone without front cam and back cam attached, only logic bord, dock connector and touch. ( and of course battery )
