  1. Connect your device to your computer with a USB cable.
  2. Press and hold both the Sleep/Wake and Home buttons until you see a Connect to iTunes screen on your device.

  4. When you see the option in iTunes to Restore or Update, click Update. Then wait while iTunes reinstalls iOS and restores your device without erasing your data. 
  5. When your device starts, tap Settings > General > Date & Time. Make sure that Set Automatically is turned on.
