Reverting the root

[emrsmsrli]

Is there a way to revert the root? like a factory reset, does it remove the telnet server?

All of the changes that this script does are temporary and lost when the TV is unplugged or rebooted, though you can run this command to also clean up temporary files if you prefer:

rm /mnt/lg/appstore/internal/downloads/myaud*

If you've also installed the Homebrew channel or any apps through it, you should be able to safely remove them using the TV interface.
