Jailbroke via Seasonpass / Installed ATVFlash - Stuck on Apple Screen

Jailbroke my ATV2 via Seasonpass. Installed ATVFlash onto AppleTV and the screen is now stuck on Apple Logo. Can you advise on what I should do to fix it?

I spoke with the support person via AIM and they advised me to do a tethered boot and now everything seems to be working correctly.
