, then with the tablet powered off, press at the same time the two buttons Volume Down and Power until the Samsung logo / recovery menu appears, then release both buttons.
, then use Volume Up / Down button to select option "wipe data/factory reset", then press Power button.
, then use Volume Up / Down button to select Yes..., then press Power button.
, once done, press Power to reboot
, then the tablet will let you re-set it up and use.
(If it does not work, try the steps again using Volume Up and Power buttons instead.)
