After trying to apply the latest update my Z8 is no longer functional. I have tried a factory reset (both methods with using the red button and pressing 1 and also with the factory reset tool and nothing has worked. I turn it on, i get the Z8 splash screen then the light on the front alternates from green to red for a couple minutes then stays green but I don't get a picture at all. It just shows a black screen. Does anyone have any recommendations on what to do, or is my box a paperweight now?
