My two ATV2 are already JB’d using Seas0npass. I’ve already took measures long time ago to prevent ATV2s from auto-updating to newer iOS.
I can see my MacBook Pro (which I used to assist in the JB-ing process) has the IPSW file. Only one though… should there be two, one for each of my ATV2? Or is that just the file I need?
Is there anything else I should do as a precautionary measure just in case my ATV2 accidentally get updated to the next iOS version which supposedly prevents JB’ing?
