If any of the above troubleshooting gives negative results, we have some more technical processes that might help. Just follow the detailed tutorials given below.

Restore Your iPhone from Earlier Backup

Click on Restore Backup in iTunes

The problem might have stemmed from some corrupt system files. While restoring your iPhone from an earlier backup, one thing to keep in mind is that restore a backup which you took before this issue was faced. Restoring from a backup which you did after the issue was faced, will not help at all.

Step #1. Connect your iPhone to your PC and open iTunes.

Step #2. Restart your iPhone in recovery mode by pressing and holding Sleep / Wake button along with Home button. Do not release when you see the Apple logo, hold it until you see iTunes logo.

Step #3. Now you will see a message in iTunes on your PC with different options like: Cancel, Restore and Update, click on Update.

iTunes will now start downloading software; if it takes more than 15 minutes, your iPhone will exit recovery mode and you will have to repeat steps 1 and 2 again. If this does not solve the problem, try one more option.

Resetting Your iPhone as a New

One of the users on Apple forum resolved the issue by completely resetting iPhone, with no backup done. Well, this is the ultimate step you can go for, as you will lose everything. So before going for this final step, make sure you have backed up your photos and videos, which you can later have it on your iPhone.

If none of the above methods helps you, the last option is to call Apple Care or visit the nearest Apple service center.
