iOS 5.1 jailbreak won't boot

I just updated iTunes (10.6.1 (7)) and the AppleTV to iOS 5 then I downloaded SeasonPass and ran the jailbreak on a Mac. I plugged it back in and it will not reboot - and a fast flashing light on the front.

I recovered it in iTunes to the Apple settings and tried again to make sure - same result.

Anyone else got the same issue?

had the same issue ! had to use the 4.4.4 jailbreake . what should the home page look like ?

 

I have exactly the same problem. The light in the front is flashing fast. 

You need to start from scratch.  Create a new ispw. then proceed with the tethered boot.

This should be in the Jailbreaking section.
