Any help would be greatly appreciated. I bought a Z4 Android box (RK3368/2GB/16GB) off Amazon as it was one of the most advanced they offered, but I can't seem to get it started at all. I try to turn it on as it says, waiting for the lights on the unit to go out, but I wait 10 minutes holding down the power button and it flashes from blue to red occasionally, and I get no picture on my screen. Anybody know what I'm doing wrong? Thanks in advance.
