Try a restart:
Press and HOLD both Vol Up/Down buttons. Keep holding while the screen goes fully black, keep holding through the Black/White logo and when the Colored Logo shows up, release those buttons.
If you have the STL100-1 variant the volume button reset method doesn't work. In that case, Press and HOLD the Power On Button until you see the LOGO as above
