I bought the LG 50UH5500 Smart WebOS TV few months back and it was working fine and I was happy with it. We dont have cable at home and mainly use apps like amazon prime or youtube on our tv - in other words rely on internet connection for using the TV. We have centurylink as internet provider and supposed to get 40 Mbps connection - however a lot of the time the internet speed is poor to be frank. So I had switched from using wifi on my tv and instead plugged ethernet cable onto the TV and all was working fine until two days back when suddenly none of the apps like youtube would open up- no error codes or anything just wouldnt open up.

Attempt to check for automatic software update would also not work.Attempt to reset to initial factory settings also would not work. Spoke to customer service , manually downloaded,unzipped the latest software onto usb drive and then plugged in the tv which would not give me an option to install the exe file in the usb drive.

1) Finally frustrated- pulled the powercable of the TV and the internet modem from the socket and replugged them in. Then apps finally started to launch back !!

Spoke to customer service why manual update wouldnt work and they helped resolve it. These are the takeaways:

1) Delete everything in the usb drive. After unzip/extracting the exe file, create a new folder with name 'LG_DTV' and put the exe file in that Then plug it in to TV and then TV finally gave me an option to install it.

2) Dont connect both ethernet and wifi to TV as it could cause internal conflicts within the TV.

3) Ensure you have a fast reliable internet-perhaps I will upgrade my 40MBPS connection to something better. This can also cause some apps to not work.


Posting it here since LG customer service is not available during weekends and I was stuck with this problem for the weekend. Sharing so others wont have to go through the same problem.

Where could I find ALL the previous firmware versions for 47LB730V (-ZD)    ?

it is so f slow... I invoke the menu and have to wait so many seconds...that in the end the subconscious reflex is to invoke it again by pressing the menu button...and this makes the menu dissapear in a split second after waiting for it so much to show...and then again pressing the menu button ...and this time shows a bit quicker finally !!!

this is because has OS a bad OS optimization ...and a slow CPU and very poor amount of memory!

But I remember this was not so with the first OS versions ...so I NEED AL THE PREVIOUS FIRMWARE VERSIONS TO TRY THEM ALL ! I know how to revert to older firmware, just need the firms! Thankyou!

43" 43UJ750V, updated today  to 04.70.06 (04.70.10 available on the support site), Italy.

Notes: looks like no major improvements at all for 2017 LCD models, no major bug fixed (no FLAC from PC/server play), got only an update for the YouTube application.

      I installed a few apps trying to get Casting to work that didn't work properly and I can't find anyway to uninstall them. My TV doesn't seem to have edit mode perhaps because I have had it a few years (pre-2018 some when- possibly its 10 years old or more as I can't remember when I got it). Anyone know how I can uninstall them?

      Hello Everyone,
      I have 2014 LG 47LB750T tv and I am happy with the TVs performance. It has just updated to newer 05.05.25 firmware. New apps are getting added in the store.
      I have been following HotStar app in my phone from quite a long time. It has a very good list of shows and movies list. I was wondering if we can have HotStar app for our WebOS tv as well. Recently DittoTV app has too been added which is a boon for those who have frequent DTH cable connection problem. It directly streams live over the Internet and package is very economical.
      If LG Developers can also introduce HotStar app for our LG TV it will be a big boost to the platform as it is very popular in India. They also have their own Original series just like Netflix which are also very good. So requesting devs to kindly introduce HotStar app for our WebOS TVs. Thank You.

      Hi all,
      hope someone can help me. I have a LG 49LX761H model 2016. I know it’s a hospitality tv but turned that mode off it works perfect. We upgrade the webos to the latest version available but the content store is not available. Is this function not available on this model or do I need to turn something on. Hope someone has the answer. Thanks

      I have
      LG webOS TV UF950T,
      software version 04.06.00
      1.)  WebOS is getting updates but new  apps are not showing up in LG  Content store.  When I visit 
      link hidden, please login to viewthrough my Tv browser there are many new Apps which are not in LG content store.         When i try to install , it says  not compatible with your Tv. 2) When i try to play a video some times it says video format not supported and some times audio format not supported like with opus & ogg.
      My question is to Manufacturers/ WebOs designers if this is the case what is the point in updating TV, when there are no apps or support for new video or audio formats ????
      In this case its like if i want new apps, I have to buy a new TV, updates are not helping in improving TV in any ways, no longer a Smart TV
