Yep, that too. Though on one of my TVs (TCL), simply disabling the inbuilt ‘startupwraith’ seems to have the same effect
# Disable com.google.android.apps.tv.launcherx which is the default launcher on CCwGTV $ adb shell pm disable-user --user 0 com.google.android.apps.tv.launcherx # com.google.android.tungsten.setupwraith will then be used as a 'fallback' and will automatically # re-enable the default launcher, so disable it as well $ adb shell pm disable-user --user 0 com.google.android.tungsten.setupwraith
