hi super 1, you need to send it back to seller and say that it s got tuner fault and if you re lucky he will give u replacement.i had dm800hd with 76 bootloader and put sll84 patched image and tuner a empty appeared i tuk it to seller and he said he changed tuner and still not worked so he gave me new one. u can try another tuner but i think it s the whole chip that got flashed with wrong bootloader so may be damaged. hope this helps and good luck
