iTunes 1600 error

I am trying jailbreak my apple atv3 firmware 5.3 and i am not having any luck. When I use season pass and it goes into iTunes to restore the Apple TV. It looks like it is going to happen. Then iTunes errors out with a 1600 message. So I unplug it and hook it up to my tv all I get is a very fast flashing linght on the front and nothing on the TV. I have tried it again with another cable and computer and still nothing. What am I doing wrong?? Please help.
