i think it is a software fault as the resets dont work. i thought Factory resets on devices should get it back to the original firmware that was installed in the factory, not really the most recent firmware as that defeats the whole purpose of a factory reset if the recent firmware is faulty. Not sure though why Samsung is not able to fix this remotely. More surprising is that the customer support agents were able to remote connect to my TV, did a reset from a service menu only they could access and saw the fault, but still they had to send an engineer who did exactly the same and came to the conclusion that it needs a main board replacement. It could have saved them money to just send the engineer with the main board and fix it in one visit and also for me that i could have a working smart hub faster.
