Have you only tried it from settings only or from phone start up menu. Switch off the cell phone. Then hold and press Volume Up + Power button until you see Adnroid logo on your screen. Select using Volume buttons option “wipe data/factory reset”, and confirm that with Power button. Choose “yes” from the menu, and accept it with Power button. Accept reboot now option.
