I used Livesuit 1.07 to flash Uberoid to the MiniX. I have no experience with 1.09 that works in a different way, and probably could be based on newer drivers. But:
Every other (custom) ROM can be flashed to the MiniX based on Allwinner chipsets.
So not only MK802 ROMs but also Wondermedia, Ainol, Novo Elf and others.
For the ones without an LCD hopefully it works with the HDMI out.
