I've turned my tv on today for the first time in 2 days and have received the smart hub is being updated message. I don't have any buttons to do the reset advised on other threads. My updates are up to date and I have ticks in all the terms and conditions
What can I do have tried all quick fixes
I had this problem and tried many suggested fixes without success.
My tv was connected via a wired network. I disconnected the ethernet and connected via wi-fi. I was immediately able to download all apps that I wanted. I went back to wired network and problem has disappeared.
TV is 2015 model UA48J6200.
