> 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.

So instead of just removing the root cause of the problem, you'd rather leave the problem in place and then maintain a permanent workaround that has to run someplace else?

Yes, the "permanent workaround" is literally permanent, it works all the time while the jailbreak solution works only when the vulnerabilities are not patched by LG.

I also prefer keeping my tv software up to date with patching, I don't want to jailbreak and keep the tv software at the specific vulnerable version.

I’m doing this as well. Works great.
