The truth is that the no name manufacturer was greedy since the 2/16 s905x m16 is really just the 1/8 s905x m16
1. Repack s905x_1G_atvXperience_v2FF.img with the following files from the stock rom
2. Now you notice you're m16 box works without video glitches on third party android because you flashed it with the 1GB atv firmware because your box only has 1GB of ram.
3. Resolution restores to 480px60 after every reboot; this one has yet to be tackled.
The only 2GB android firmware that works for this thing is the stock image, nothing else, that's why this box is a fake 2GB ram offering, and that's why it was hard to pin down.
Go here for my findings.
