My Mecool HM8 doesnt have a reset button hence I only can use mask rom mode when burning by touching the pins internally after opening the box to detect it on amlogic burning tool. Would you be kind enough to give me the link of the exact image you used so i can try again? I dont mind not having wi-fi as i can use ethernet too. Just need it to be more seamless than atv7.

My tv box has reset button but It didn't work when trying to upgrade from Aidan's Rom ATV7 to ATV9 so I had to touch the pins as last resource and It did work. Maybe for your tv box could work too.
