Need help. New to Forum.

Hi All,

I jailbroke my ATV2 years ago using SeasonPass. I want to update the firmware on it so I can use AirPlay speakers and the other new features that aren't available to me.  I've downloaded the current SeasonPass, but it doesn't recognize my ATV2 as being connected to my Mac.

Can you provide guidance/a link to the steps I need to take to update my jailbroken ATV2 to the most current firmware that can be jailbroken?  I've read and read, and I really don't understand what I need to do or if even updating from my current iOS version (in the 4s) is even possible.

Thanks so much.
