Question: I have the F9000. Will the 2 old remotes that originally came with the tv work with this Evolution kit?
Document: I have the same problem....I just installed my new SEK2500U onto my UN65F9000 and the NETFLIX app was de-installed as a part of the process....THIS is very, very frustrating since the unly reason I spent $400.00 on the upgraded Evolution Kit was so that I could watch 4K UHD video on NETFLIX!The other interesting issue I experience is that it would not work with the old cable?
But Breaking Bad is all 2160. I'm really happy with the Evolution Kit. I listen to my tv with bluetooth headphones so 5.1 surround is not an issue for me. Netflix only plays in stereo (maybe another fix by Netflix not Samsung)
I have no video distortions, and all 4K and lower resolution programs have blacks that are identical to before the upgrade. The smart functions all work, but they've been rearranged somewhat. A new remote is included that's less substantial than the two original remotes that came with the UN65F9000.On Netflix, House of Cards 2160 isn't a stunning change from 1080. It is better, just not dramatically so.
This kit does not work because the firmware is broken. There are near-unanimous complaints  & horror stories in the following forum thread:[...]Various complaints - Netflix disappears, colors are completely washed out, blacks have become gray and TV is unwatchable, TV doesn't come on etc.And this is not new - the SEK-1000 (last year's evolution kit that's been available for more than a year) also has bad reviews and still appears to have many problems.
I haven't checked since the last update if Netflix is back yet or not, but the original cable was bad causing flickering/jiddering with the overlay from the menu. I called Samsung for support which was worthless until they sent someone to my house (pretty cool warranty). They said if they couldn't fix it, they'd upgrade me to a 2014 version of my F9000 tv.The tech got me a new cable, and the jiddering went away.
After reading on all of the troubles and nightmares with the initial firmware when the sek-2500 came out, I waited until I saw some positive results and the firmware was in good standing. I was very nervous about installing it even though it was super simple. I was just hoping for a clean install and I got one. The processor is much faster in the new 2014 UHD kit and the TV seems to handle motion better in my opinion. The blacks are much darker also.
I bought my Evolution Kit directly from Samsung. I waited until they listed it on their website - June 4. I know others were able to get it a couple of weeks early from other merchants, but after reading about trouble with the early purchases on some AV forums, I decided to not get it before it was officially on the Samsung site.
I bought this from PCnation, @$298. and first, like others mentioned, the picture quality looked washed out, now with the new firmware update, it looks and performs better.. Tho its still missing Netflix  as of today 6/23/2014****update**** as of 6/23/2014 5:23 , Netflix UHD is now available for the Samsung 2013(with UHD evolution kit)-2014 UHDTV's  cheeers
As of July 17, 2014 - The first kit would not install. Sent back for a second kit. It installed successfully but on all inputs, HDMI, USB, and Smart Hub apps (Netflix, Hulu, etc) the picture flickers constantly. I have 6 support tickets for different calls to Samsung support without any resolution. One of the techs told me that only 4K inputs would work with this kit. Didn't want to argue with him, so I called back to get someone else.
After using it for a week or so, everything is working as expected. I'm still waiting on the Netflix app, but to be fair, I haven't checked since the first update. They do have a message that the app is being worked on and will come... that it's not a bug that it's gone, just needs a new version for the codec.So, if you're having jidder issues, just use your old OneConnect cable, it's the same thing as your new one.
Answer: They work with my 2500 Evolution Kit
