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 Volume up key and the Power key at same time until
the screen lights up.
