I have a MK809IV android devide that was stucked some time ago on the booting sequence all screen was black and only the mouse cursor can be seen. I have tried to reset it from the reset button but nothing happened. After that I tried to restore the firmware usign Rockchip batch tool but everytime I get this error message I have tried lots of firmwares but everytime get stuck with this error. I have also tried to short circuit the pins on the chip but nothing happened still stucked in this paranoia error. 
Thank you!
