Performing a factory reset via settings
The most convenient way to do a factory reset is
via the phone settings.
On the Home screen's Settings tab, tap Menu >
All Settings > System > Clear Storage.
Enter 1234.
Tap YES to perform the reset, or tap NO to
cancel the reset.
Performing a factory reset using phone buttons
If you cannot turn on your phone or access the
phone settings, you can still perform a factory
reset by using buttons on the phone.
With your phone powered off, press and hold the
VOLUME UP and VOLUME DOWN buttons.
While holding the volume buttons, press the
END/POWER button briefly and then release it.
When you see a warning message on screen,
release the VOLUME UP and VOLUME DOWN
buttons.
Press the VOLUME UP button to perform the
reset, or press any other button to cancel the
reset.
Back up your data before doing it....
