What files are needed for final tether?

I’ve tether jailbroke my ATV to 5.2.1 and would like to move my ATV… but the TV is far away from my PC. What I’d like to do is use my laptop for the final tethered part. Since I’ve already created all the files on my PC, what files will I need to copy to my laptop to make this possible.

I know I’ll need the season pass, but which ipsw will I need?

You will have re-do the whole process (minus the restore in Itunes ) to let season pass redownload the AppleTV2,1_5.2.1_10B329a_Restore.ipsw & recreate the AppleTV2,1_5.2.1_10B329a_SP_ Restore.ipsw  before the tethered boot button appears
