i have looked everywhere for a cure for this problem but cannot find it anywhere! when i jailbreak my Apple TV the flashing light stays on, i kept the usb plugged in for just over 10 minutes and i thought the light would have stopped flashing after i unplugged the usb and put in the hdmi. but nope, 2 hours later still flashing and i cannot get anything on my screen until it stops! someone said recboot but i dont know how i would be able to put that on the apple tv to run it! heeeeeelp!
