  • Hi All,
    Please I need help, My DM820 suddenly crashed yesterday and when i tried to restart it, it hangs and stops booting, the OLED keeps showing DreamBox Logo and nothing happned.

    I've tried to go to Rescue mode and to upload several images and it throws an error "warning had trouble writing out superblocks"

    Can anyone guide me what can I do?

    I've tried to update the rescue loader and the same issue
