Help, can not lower the firmware from 04.70.30 to a lower one, I get the message "Software update can not be applied to the TV". LG oled55B7V.

I get the same message. According to forums and people around it is a block on 2017 oled that prevents you from installing older firmware. 

Has anyone here successfully downgraded a 2017 oled?

I am currently on 03.60.09 and not happy with the changes they did to the HDR Game Mode (too dark). That's why I want to downgrade to 03.51.20

Where did you get your software file from? Are you sure it's a EU version?

Let me know if you find a way to downgrade the software.

Finally Apple has admitted that they are software "

" the iPhone (I prefer to replace the battery), I think we will find out soon that TV producers are aging LED technology in the same way, the client must be directed to OLED technology.
I just bought a brand new LG WebOS UHDTV, the image is like on my old LG NETCAST UHDTV before downgrade :-(.
I think the case is lost :-( it is an 2017 model and there is no older firmware.
I am thinking to return the TV and buy another brand.

PS Apple become very aggressive with the iPhone iOS update :-(. Periodically the phone ask the safety code to start the automatic download and overnight  installation of the latest iOS. And unfortunately there is no jailbreak to stop this :-(

hi i have 40ub800v after downgrade and factory reset tv freeze after 15seconde after power on i find jtag connection in motherboard but i knew any flasher or how flash it who have idea or any solution thanks

Hi

If the TV don't respond to any command using classic remote control or the TV button (maybe the smart Remote control are not paired anymore) and the resoft process was without errors or with no power cut until the process was ended, that looks like there is a hardware issue and you have to replace the flash IC :-(. I'm afraid you have to contact an authorized service for this :-(, they have an already written flash.

When was your last firmware upgrade?

      I was tying to change the settings on our LG TV to enable it for HD channel reception. We found instructions on the net to configure the "area option" in the hidden menu, however, they did not work. So, we thought that we need to change the country group to be able to receive the HD channels. Although we could not change the "country group code" from 20 to an arbitrary number, we change it to 13. After that, we have not been able to change it anymore. It is struck there. I know this is ridiculous, but an LG TV expert who is working in LG customer services told us that I could not change it either and we need to replace the IL.

      Please tell me why I could not set the "country group code" to 20 once again? It is gray meaning that is unchangeable. Any ideas will be appreciated.

      After updating to the latest web browser with new UI, closed caption subtitles on ALL websites video including Youtube.com disappears every 2-3mins. Video continues to play without subs and subs will re-appear if I move the magic remote but disappears again after 3mins.
      Model - OLED55B8PLA
      WebOS - 4.3.0.9604
      Software version - 05.30.10

      The bowser no longer displays PDF files.  Several online PDF files that were bookmarked in the previous browser version won't open now.  This version just says "downloads not allowed".  But I don't want to download (and save), I just want to open and display them.  The previous version had no problem with this.
      So far. this newest browser seems to be a major downgrade...
      Does anyone have a workaround for this, or any of the other problems I mentioned before?

We look forward to bringing these new customers into the incredible world of webOS TV.”

      I have a LG TV model: 47LB652V-ZA, webOS version 1.4.0-2523 (afro-ashley). Why isn't Spotify supported for this TV if its from 2014 and it says that devices from 2013 and onwards will be supported
