Resetting the phone
You can reset your phone to its original settings. When you perform a factory data reset,
you reset the phone to the state it was in before you turned it on for the first time, and all
personal data is erased. You can also reset the phone to the original settings, without
erasing your personal data. Before you perform a reset, be sure to back up any
important data saved on your phone.

To avoid permanent phone damage, do not restart the phone while a reset procedure is
underway.
