Factory data reset
Erase all of your personal data from internal phone storage, including
information about your Google Account, any other accounts, your system
and application settings, and any downloaded applications. Resetting the
phone does not erase any system software updates you’ve downloaded
or any files on your microSD card, such as music or photos. If you reset
the phone in this way, you’re prompted to re-enter the same kind of
information as when you first started Android.
When you are unable to power on your phone, there is another way to
perform a factory data reset by using hardware keys. Press the Volumn up
key and the Power key at same time until the screen lights up.
