The MiniX, MiniX Plus and newer Rikomagic MK802 II / Zero Devices Z902 look all different, but are the same underneath. They can be flashed with Phoenixcard instead of Livesuit.
Livesuit IS possible, but requires additional steps in order to set it in recovery mode, so that Livesuit will recognize it.
Time to analyse the MK802II build.prop which I have extracted from firmware 1.1.
Rename to build.prop after download.
