I can't update my samsung smart tv and some of my features are no available in my menu. I get the Error 800 resours error. Also, I get the message: smart hub conn. test unable to launch apps. my model number is un55j620dafxza
I'm sorry to hear that, how do you have the TV connected to the internet? Also, have you tried to factory reset the TV?
How do you have the TV connected to the internet?
Try connecting your device with an ethernet cable to see if it updates this way.
