[Needs Root] UN55HU6830 55" 4k UHD Smart TV

Well I have Unix/Linux experience and Skype and a T-NT14 firmware, but I guarantee I can't disable OTN more than it already is.

Hehe. Let's hope than that "greyed out" means disabled. So just do what I suggested (set OTA Support to OFF and disable automatic updates in normal menu). We still don't know whether now Samsung:
1) Always updates
2) Uses OTA status for OTN updates
3) Uses user's choice from normal menu instead of (previously used) OTN Support.

Why can't we get it rooted without any internet access and then see if we can get the ability to disable OTN by hacking/modifying the service menu, since now we're rooted?

First of all it is important to know that "auto-update stuff" start BEFORE ANY ROOTING METHOD. Also it's possible that OTN Support greyed out means "ignore" So it might not matter what we set there since it will be ignored

I can disable the internet access to the MAC address for both Ethernet and WiFi on my TV so that it can still use LAN connections but will never update from Samsung.

Glad to hear that. Most users don't want (even when risking auto-updates) disabled internet access. I think it might be a good idea. We never know what next "update" will bring

Cool: can we get the ball rolling or do you want me to try the method you already have before we skype and try things out?

I'm the only one who uses Netflix and I finished Daredevil already. Season 2 isn't due for about 6-10 months. I only used Netflix to watch 4K UHD content.

The only other internet thing I use my TV for is to play Movies or TV Shows on my network harddrive, but really, it's only for my daughter and my wife doesn't watch too many movies at all.

So I am perfectly ok with having no internet while we try and root the T-NT14 firmwares.
