- pkill does not find the power service, so use pkill -f instead in restart_power_hal - rename touch-specific functions - add functions to disable launch boosts and restore defaults Test: ran restore_defaults & disable_launch_hint and checked powerhint.xml on device; ran restart_power_hal and confirmed service restarted.
