Unfortunately you cant turn it off or pull the battery out!
Doesnt work when pressing Power + Vol UP + Menu or Power + Vol Down + Menu or just holding the Power.
Here's what i did. In Download Mode, Press and hold Power + Vol UP + Vol DOWN
It should restart the device successfuly.
I hope it helps.
All you probably did there was as above as you had the VOLUME DOWN button pressed.The procedure can be used anytime the tab s is on. Its the equivelant of a battery pull.
