Factory data reset
To activate factory data reset:
Touch on notification panel to get to Settings.
Touch Backup and reset\Factory data reset
Touch Reset phone\Erase everything
Phone reset will 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 mark the checkbox ―Reserve the content of Phone
storage‖ before touching Reset phone, any files stored on your phone’s
storage will not be erased. 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.
