I have the same model as you - 55UF7787-ZA. Today I've also got update to 04.00.70

If you look at the LG website you won't even find this firmware version. Only the two you've mentioned in your first post. So dont expect much from the website :)

I also tried earlier to update to 04.20.50 via USB and it also didn't work. It relly anoyed me. Later on I've found on the lg's software page that there is a link "View More" below firmware download link, and when you click it you can see the list of all supported models.

And for some (probably stupid) reason our model is not listed there. Pay attention to the last two letters of the model - "ZA" - that one you wont find in the list. But if you look under 04.00.40 - you will find our model.

And now everybody is getting 05.00.50... It seems that we were wront to buy this model....

By the way, can you see the Netflix app in the app store?

Hello, Sasa,


no, I don`t have Netflix. In my other LG model netflix installed automatically. But I do`n need netflix because I like watching only new cinema movies and not in english.


Do You like this TV? It very slow.. And I see frames when watching fast video.


Maybe we can change model letters from "ZA" (South Africa) to "UK"?

If you asked me this 2-3yr ago I would say yes I like it. But know, I do not like it at all - as I had different expectations when I was buying it. The the reviews said that 2015 models have much faster procesors and superior screens. And what I've seen is slow menus and channel switching, as well as some stupid bugs / issues. Not to speak about completly bad customer support (site is just...), bad built quality (I've noticed that the panel is moving when applying minimal pressure to clean the dust), missing app support and strange firmware update cycles. I wouldn't buy it again...

I did not know that "ZA" stands for South Africa. I live in Montenegro - in West Balkans, so its quite strange to me. Maybe the TV fell of the truck and right into the retailers store :) it isn't unlikely in my country :(

Only way that I know to switch the model is to return it. In my country it is not possible to return something you purchased unless it is malfunctioning. Maybe it could be forc flashed with some other firmware - but it's a gamble I am not prepare to take :)

What can I say about this model: Very slow. Slow channel swiching. Bad picture: I see frames in fast videos. Remote control not comfortable. Don`t remember my audio language channel choise (every time when I switch channel, need to swich audio). UHD playing is horrible. It`s last time when I buy LG. I live in Lithuania.

Yes quite slow. Quite bad picture. You can improve it a bit by selecting Expert picture mode and messing around with additional settings, but this is limited. You can't make bad thing look good - only a bit better :)

I don't have the issue you mentioned. In settings there is an option to select first and second default audio language. Did you try that?

      I have a 55UH6150 LG Smart TV and was wonder if it was possible to update it to version WebOS 6. I have some apps I would like to install but sadly they are only avaible on the content store from WebOS 6+. Is it in anyway possible to update the SW for it?
      I know the page doesn't show WebOS 6 listed for it, but am curious if there is a way I can do it anyways
      Any information would be much appreciated

      Hi Team,
      After update of LG WebOS to 04.40.70, Amazon Prime Video app on my LG Smart TV stopped working. It started giving error :
      Internet Connectivity Problem
      There is an internet connection problem. Check the device's internet settings, data cables, or try to resetting your router. Also, turning your device off, and then back on might fix the problem. For further assistance, please contact Amazon customer service at www.amazon.com/videohelp
      The internet/wifi connection is fine and all the other apps are working without any issue on the LG smart TV.
      I have even tried uninstalling and reinstalling the Prime video app, but that didn't help.
      Has anyone faced this issue ? Is there a solution available for this issue.
      Thanks & Regards,

      Hallo, I bought a 55un74006LB smart tv in Italy. It seems not to have usb recording capabilities, according to the information on the italian website, but the UK site declare it has. I think it's the same product with the same functions, so how can I turn the live tv and usb recording on? I think I found the options in the service menu but I cannot change the values. Any suggestion?
