I've been searching through past posts, and I have not found a question/answer for my particular situation. Please forgive me for the question.
I've bought a SEK-35000 Evo Kit, and yesterday tried to install. It was unsuccessful. I realized my UE65F9000 firmware too old to SEK-3500 (1310). I tried to upgrade via Internet, but it said this is a latest firmware. It was suspicious, because on support site found 2235.6 vers. Then came the shock. Under the TV's support menu my UE65F9000 TV has T-GFP9DEUC-1310 software version. It is belong to UH8500 type, not to mine.
Could Somebody help me how to revert to original T-FXP9DEUC version?

Yes, remove evokit

Evokit turns your F into H so you now have H firmware, nothing strange. Firmware numbers can't be compared between series, moreover the greater is NEVER the better...

Thank you for your prompt answer. I hoped this is a reason my problem.
Do You have any idea about unsuccessful upgrade?
I've got attached message. I've selected upgrade menu with old one (SEK-2500), then replaced (unplugged from mains) and got this message. The new one did not find the saved data.

1310 is latest, simple as that
