How to restore my Apple iPhone 6
You can use iTunes to restore your Apple iPhone 6 from a previous backup.
Note: Restoring from backup is different from performing a full software restore. Restoring from backup restores the settings, data and other information saved in a previous backup. Performing a full software restore will delete the contents of your device and restore it to the original factory settings.
In this example, we use iTunes v11.1.0.126.
1. Ensure your Apple iPhone 6 is connected to iTunes.
2. On the computer, select your Apple iPhone 6.
3. Select Restore Backup…
Note: iTunes will not offer this option if no backups have been performed.
4. Use the drop-down menu to select a backup, then select Restore.
5. Wait while the backup is restored.
6. Click OK.
7. Wait while the Apple iPhone 6 is synced.
8. The restoration is complete and the Apple iPhone 6 can be disconnected from the computer.
