I have a CuBox-i 4 (not 4x4). It's currently in stable use, and have not fiddled with it for long (and right now, it sits 7000Km away from me), but if I recall correctly, any USB media needed for the boot process (i.e. a keyboard) has to be inserted in the lower port. I know the issue seems completely different from yours, but this might be an important point to get your issue properly solved.
