It's called a "Home Theater Box, 4K Ultra HD Home Theater Box". So I want to do away with cable and hook this box up for watching TV. No directions with it. It came with a mouse, cable, power cord, USB plug and the small box to hook everything to. Do I hook the cable up where I unplugged the cable cord in the back of the TV? Which port should I put the USB to connect the mouse? The TV says android when I connected the power cord to the box. Ugh, need help!
