Q: Guided Access

Force restarting will disengage Guided Access.

To force restart:

Hold both the home and power buttons at the same time until the Apple boot logo appears.

1. Connect your device to the computer that you stored your backup on.
2. Open iTunes. If iTunes tells you there's an iOS update, get the latest version.
3. Go to File > Devices > Restore from Backup. If you're using Windows and don’t see a File menu, press the Alt key.
4. Look at the date and size of each backup and pick the most relevant.
5. Click restore and wait for the process to finish. Your device will restart and then sync with your computer. Stay connected until the sync finishes.
