Ouch… usually this means game over and you now have a bricked (= it’s as useful as a brick because of firmware flashing errors) machine.
This seems a 2 year old standalone media player.
After it was released to the public it seems that the Hantech company has dissapeared.
I have found some firmware files right here but i have no idea if they work or not.
Check the manual first. Is there some sort of reset button? Some sort of “restore original firmware” option?
