You can also reset your device to its original factory settings, with or without deleting
some of your personal data, such as music and pictures. This action is sometimes
necessary if your device stops functioning properly, but note that if you want to keep
any important data, you have to first back up this data to a memory card or other
non-internal memory. For more information, see
Backing up and restoring content on
page 188.
Your device may fail to restart if the battery level is low. Connect your device to a charger and
try restarting again.
