Restoring to factory settings

You may perform a clean boot to restore your smartphone to the
factory settings. Before performing a clean boot, ensure that your
smartphone is not locked. Press any key or tap the screen to see if
the phone responds.
Important
You should only perform a clean boot when all other options have failed
to restore your smartphone to an operational state.
This will erase all your personal information, any contacts stored on
your phone and any programs you installed.
If your phone is responding to screen input, then open Settings from
the Application menu. Tap Backup & reset > Factory data reset >
Reset phone and then Erase everything to format your phone.
If your phone is no longer responding, press and hold the power
button for 15 seconds to restart the phone.
