Why did I make a repo for this. Jailbreak package to disable updates on tvOS 9 - 26. Probably.
This does the exact same thing as Stasis, just without the UI fluff. This is literally two shell scripts. There are zero binaries here. Works on any jailbroken Apple TV or something. I think. Probably. Tested a lot less.
