Hello everyone, i need to help to downgrade my 43UJ651V tv. I succesfully apply all steps and at the last step seems this error message in the tv screen:

 

Update failed because software version is earlier than the version installed on the TV.

 

5.80.50 version installed on the tv now. But i want to return 04.70.55. Is this possible? Can anyone help me about this? Additionally, i am in Turkey. I want to install real official firmware. Can anyone send me the right firmware for me to install 04.70.55 ( I dont want to have language problems. I see the LgDTVUpdater package RU version)?

Hello friends, i think i found a way to downgrade 2017-2020 models tv (now its not possible by using current methods). The process is carried out through a computer using an RC232 cable. Can we overcome the obstacle to revert to old software using this method? Do you think this is possible? The link I provided is in Turkish, but you can translate it into English.

      Area Option locked on 2024 QNED (webOS25) - Russia unit, need ME/CIS unlock
      By Farhad Radka
      Hi all, hoping for some expert help.
      TV: LG 65QNED86T6A.ADKFLJD (Russia-market unit, now in Iran), S/W 33.31.68.01 (webOS25), 2024 build.
      Location settings only show CIS/Russian-speaking countries.
      Using an original Factory SVC Remocon (WK-17226), both IN START and ADJ (code 0413) lead to the same SVC menu.
      Current Area Option values: Area Code 3638 / Continent Index 54 / Language&Country CS / HW Settings EU.
      I've tried entering various Area Option codes (adjacent blocks 3712/3840/3968, and legacy ME/CIS codes from older webOS threads) — all rejected with an error. Continent Index / Language&Country / HW Settings appear to be read-only/derived fields, not directly editable.
      Has anyone successfully changed the Area Option on a 2024-model webOS25 QNED TV? Any known working codes or is this generation's SVC menu fully locked without RTOOL/GSDF access?

      My 50UT80506LA LG WebOs TV does not support my office security camera system via wifi to TV. We need (gCmob app) in list of app.
      By Ramesh Chand Vishwakarma
      It is unprofessional on part of LG TV that they do not resolve the basic issue of adding app gCmob in their app store.

      I can't connect my office camera via Wi-Fi to LG-TV. No body in LG TV technical team is proactive in resolving the issue of customer. They are more happy to befool the customers, rather than looking for technical solution through wider thinking.
      Please talk to you top management and make a visit to our office to understand the customers plight..
      Please respond to customers needs.

      Laptop Wireless Display Problem
      By Ozgur Yalcin
      When connected to the TV with a laptop, black boxes appear on the screen. We tried this with many computers. The result is the same. What can I do.

      Slight soap opera affect after latest firmware update
      By Matt79
      I've just updated my LG 55UM75 TV to the latest software version - 05..20.15 - and now the picture looks off.
      I've turned off TruMotion, Motion Eye Care, Smooth Gradation, Noise Reduction and Smooth Gradation, but somehow everything still looks artificial.
      Is there another picture setting I'm missing, I've gone through every setting I can find.

      YouTube app problems, please help!
      By Simon1973
      I recently bought a 50NANO90A6B TV and so far I have to say it's a fantastic upgrade from my old Sony 40".
      However, I've one small niggle problem (only had the TV since Sunday)... The YouTube app doesn't seem to want to work! it shows the logo with a spinny circle, then the logo starts again with the spinny circle... this just repeats over and over.
      All other apps (iPlayer, Jellyfin, Plex, ITV, CH4 etc...) work as does the LGTV app, so the WiFi connection is fine!
      I've uninstalled and reinstalled the YouTube app a few times, but it does the same each time!
      Anyone know how I can sort this? any other suggestions for fixing it!
      I'm currently using my Chromecast with GoogleTV for YouTube at the moment.
      I'm in the UK by the way! And the TV is set to that, in all the relevant settings locations.
