There’s a built in ATV Flash feature I use often that reboots Lowtide to free up memory. Would I need to connect the AppleTV to my PC to boot it? Or is that only necessary from a cold reboot?
Rebooting Lowtide does not require you do a tethered boot. That is not reloading iOS itself, but merely the Lowtide app that is running as a client program under iOS.
