hi i need help with an MK809IV clone on the PCB is printed 809III v5_2 20141105 and it is equipped with an RK3188T and a RTL8723BS with the stock software there where reboots every 30 minutes and the device gets extremly hot. So i tryed a lot of ROMs from that link http://freaktab.com/forum/tv-player-...om-ruskie-site but nothing worked everytime a got a bootloop. The only that worked is that one http://freaktab.com/forum/tv-player-...9iii-rtl8723bs but this one get no root access TPSparky and KingoRoot does not work. TPSparky says all ok but there is no root SuperSU says SU cannot be updated and Kingo says there is root but No Frills Cpu Tuner says there is no root.

Can anyone help me to root the ROM or can give me a link to a Custom ROM
