When I bought my smart TV I've decided to not connect it to my WLAN and didn't plug in the Ethernet. So it isn't able to send information or install anything.

When I bought my smart TV I've decided to not connect it to my WLAN and didn't plug in the Ethernet. So it isn't able to send information or install anything. Everything I watch on it is through my home theater PC. If I ever wanted to update it I would connect it with Ethernet and then remove the ethernet cable after the update.
