> You don't really need to jailbreak your LG tv to install custom apps(like adfree Youtube), you can just put it in developer mode and have a cron somewhere(I use Pipedream) that keeps activating developer mode every 24h or so(it deactivate itself every 48h)

I've been doing this as well. I love the idea of rooting but not being able to get system updates bugs me a bit.
