Factory settings
If you reset the phone to its factory settings, you can delete any data and settings saved on it. This includes, for example, deleting personal data (such as your contacts), function key assignments and identities.
The phone is shut down and then restarted. This can take some time.
Note: If you reset the phone to its factory settings, you can delete any data and settings saved on it. All personal data is deleted. You cannot undo this action. To save particular settings such as a configured identity, you can first perform a data backup.
