I have a ATV 2 currently jailbroke on the original 4.1. I am thinking of updating to 4.2.1 and going the tethered jailbreak route ,but my concern is lets say I ssh plex onto my ATV and have to killall Lowtide or I believe its killall AppleTV on 4.2.1, does that cause you to have to go through the tethered boot option or is it just when you reboot??
