Apple TV flashing / not starting after jailbreak

Says it in the title: Apple TV (2nd gen), flashing / not starting after jailbreak. Had it on the previous version, just ran Seas0npass, then unplugged and hooked it up to the TV and outlet. Trying to run Flash (black) but it’s saying it can’t find it. It’s plugged into the TV, but it’s just flashing rapdily and the TV’s HDMI will not display anything.

what version of seas0npass did you use?
