If you’re having issues with your iPhone, iPad or iPod touch, and none of the basic troubleshooting tips have helped, then you can try restoring your iOS device to factory settings to see if it helps.

Important points before we show you how to reset or restore your device to factory settings:

• Make sure you’ve the latest version of iTunes installed.

• Restoring your device will erase all the data from your device, so please take a backup of your device using iTunes to transfer and sync any additional content to your computer, so you can restore from the backup.

• Disable Activation Lock by turning off Find my iPhone if you’ve enabled it. Launch the Settings app and navigate to iCloud. Tap the Find My iPhone On/Off toggle to disable it.

• Please note that restoring your device from the backup can be a time consuming process, and depends on the amount of data stored on your device and on the speed of your Internet connection if you plan to restore from iCloud, so take up this activity when you have enough spare time.

Restore your iOS device:

• Connect your iOS device to the computer.

• Select your iPhone, iPad or iPd touch when it appears in iTunes (next to iTunes Store button in the top right corner).

• Click on the Restore button in the Summary tab.

• iTunes will prompt if you’re sure you want to restore your iOS device to factory settings. Click the Restore button.

• After your iOS device is restored to factory settings, it will restart.

• You’ll see the “Hello” screen with a “Slide to set up” slider. Follow the on-screen instructions to setup the iOS device. You can set up your device as new device or restore from the backup taken previously. If your iOS device has cellular service, it will activate after you restore.
