NastyNoble:pyronical: Ah ok, sorry the SEK-3500U will only work with the F9000. The F8000 cannot be upgraded to tizen / freeview plus.
It appears that you are correct from looking on other websites from searching the SEK-3500U. I just don't know why that I have an evolution box on my model and it is not upgradeable although it was sold under those pretenses. I wonder if there some kind of legal action I can take. I feel ripped off by Noel Leemings.
Give it a shot. They promoted those kits as a way to get more life out of your TV and you are now finding that not to be the case. Prime example of where the CGA should be put to use.
