My MK809III B (buy on DX) have some trouble. With the original ROM, i had a lot of freeze, crash which seems to occurs randomly. Because of that, i've decided to flash using some other ROM (i tried a lot of them using MK809III). With all ROM, my device boot and reboot. It seems to be locked in a infinite loop. The flash seems to work well because depending on the ROM the initial screen change. I don't have the original ROM and ask for your help. If any have an idea to solve the problem or have the original ROM which will be better than having just a blank stick tv key.
