UN46ES7500 3D TV smart hub never starts.

[prabhushrikant]

Since a few months back , smart hub on my TV started updating very frequently (almost daily). So I called samsung support and they updated firmware on my tv to T-ECPAKUC.10059 which is latest for my model. But then after smart hub never started.

Sometimes smart hub comes back on when I do Factory Reset but as soon as it shows up, it starts updating to latest version. How can I disable automatic smart hub update? Looks like new smart hub is not compatible with current firmware on my tv. Whenever I hit smart button tv remote it would say "smart hub" is updating , then installing and then tv shuts off and restarts quickly but smarhub never shows up.

I have also observed tv has stopped recognizing wireless connections so tv never connects to my wi-fi network. It's only working with Ethernet connection (whenever smart hub is connected)

Another problem is if I switch off tv using power off on tv remote , it would NOT switch off completely as in it would turn back on. Also most of the times it non responsive to remote button presses as in little green light near my tv camera which senses tv remote blinks but nothing happens.

Please provide me the direction so that I can try a few tricks on this website. Or tips to downgrade firmware on my tv or stop smart hub updates.

Thanks,
