Thanks Tema, if I understand properly I have to make my tv believe my laptop is the lg update server with some software and some DNS trick. Unfortunatly I am on a Mac so not sure it will work.. seems rather complex as well most likely going to wait for the official update too bad we can't simply update from a Usb key. but thanks anyway

Procedure to update via USB is:
1) Make in USB disk, folder named LG_DTV
2) Copy firmware *.epk in LG_DTV
3) Connect USB disk to TV


For LG store.

Make sure you take all agreements with LG and check if there an error in the address of the DNS server. Verify that no error in the country to use the TV.

In a pinch, call service support.

Thanks vkomitov will try to update through usd. when I get home! and I will report back (FYI I did check the dns settings for the wireless connection in the network section of the tv setup menu it is fine, I did accept all the agreement "from the about menu" and try different country with no luck...)

      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)?

      Ciao, possiedo un tv lg 55uh650v era impostato su posizione Russia e dopo all'aggiornamento del firmware versione 05.30.45 non riesco più ad usare le app in quanto non riesco a accettare i termini contrattuali. Ho provato a cambiare il DNS e a collegarmi tramite cellulare ma non ho ottenuto nessun risultato. Ho provato più volte ad eseguire il reset di fabbrica ma nessun risultato. Inoltre ho notato che la versione del mio firmware non è presente sul sito LG Italia mi chiedevo se fosse possibile tornare ad un versione firmware inferiore, potresti aiutarmi?
      Hello, I own a TV lg 55uh650v was set to Russia position and after the firmware update version 05.30.45 I can not use the app anymore because I can not accept the terms of the contract. I tried to change the DNS and connect via mobile but I did not get any results. I have tried several times to perform a factory reset but no results. Also I noticed that the version of my firmware is not on the site LG Italy I wondered if it was possible to return to a lower firmware version, could you help me?
