I already tried resetting the smart hub but no luck. It still saying " smart hub is being updated. Please try again later" I even tried changing the location, the DNS, nothing happened.
Same issue, from Hungary. I've just now finished with Service, they have reset SmartHub from factory menu but no success. Complete factory reset, reset apps, reset smarthub, no success.
What I can see in smarthub menu, that the available memory is just 82 MB. And no any application is installed currently. How it can happen, that after factory reset, something is blocking 90% of the memory...?????
I think, something has stuck in the memory, and causing false status for smarthub server... Just a hint.
Issue is SOLVED with EEPROM reset.
Press the physical ON/OFF button on the TV for at least 3 seconds, then press the ON/OFF for at least 3 seconds on the remote within 10 seconds. TV must restart 2 times, and goes back to virgin factory mode.
