or won't restart normally. No settings or personal data get deleted.
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
