For those of you here stuck on 05.30.25 and wanting to downgrade:
I was able to install http://su.lge.com/GlobalSWDownloadC....k2l-4301-05.40.01-prodkey_nsu_V3_SECURED.epk onto my USA
B6 using this method and then downgrade back to 04.31.20 using the same method.
Let me know if that link dies and I can try to provide a mirror.
Get yourself through to someone with the authority to exercise some discretion, then lay it on thick: “I thought i was buying a premium product”; “are you really telling your customers that they should expect your products to only last for just over a year, is that what your brand stands for?”; “are you really satisfied with telling me that I should pay £1000 to fix my LG TV, after I decided to choose your brand, and pay £1500 for one of your flagship products 16 months ago”.
I’ve been successful on more than one occasion in getting manufacturers to agree to foot the bill for repairing out of warranty products with this approach. The key is making sure you are speaking to someone with the authority to make a decision, and not just some call centre bod with a script.
Also, it’s worth reading up on your consumer rights, there may be something there you can use.
Do you know if it works on an european B6?
Try this http://su.lge.com/GlobalSWDownloadC....k2l-4303-05.40.03-prodkey_nsu_V3_SECURED.epk for euro tv?
I can't test because I don't have a european TV.
Tks, I will try
Unfrotunately neither were recognised in my european B6.
Can you post the exact file name of at least one firmware file that you know for sure your TV recognizes?
By European B6 do you mean UK? I think there are quite a few different sets throughout Europe.
Here goes: starfish-dvb-secured-k2l-43.dharug.k2l-4308-05.30.25-prodkey_usb_V3_SECURED.epk
Portuguese (https://www.lg.com/pt/suporte/suporte-produto/lg-OLED55B6V), but I never had issues on installing UK or those beta firmwares leaked by russian forums.
The Polish firmware 5.30.40 works on my Swedish TV which seems to be the same as the Portuguese V-version. It should work for V-Z versions. Do not know if it works with downgrading and of course it is at your own risk. I will not downgrade. In my almost dark room, not pitch black, it is an excellent tv LG OLED55B6J Wsparcie produktowe LG :Instrukcje Obsługi, Warunki Gwarancji | LG Poland
Polish version installed.
Tried the LGDTVUpdater to downgrade to version 04.03.50 (followed guide found in LG B6 OLED TV Owners and Discussion Thread - Part 6), tv notifies that it will install the firmware but then the progress bar doesn't progress at all - any clues?
Has anyone actually checked 5.30.40 for black glow?
You can't roll back firmware from 05.30.40. I've just tried.
Doesn't work on my North American B6 (Canada)
Hmm, mine is american...
What exact error/issue are you having?
When I plugged in USB stick, there was no popup. I've installed many firmwares this way in the past so not sure why it's not working.
I got it to work using the network method here (for both the upgrade and the downgrade). Its a bit complicated but it worked for me. Not sure if it would work from usb.
Yeah I've updated over the network before and just realized what I did wrong, didn't change IP settings in TV. Willl try again.
You managed to downgrade 5.30.40?
I downgraded from 05.30.25 on my USA OLED65B6P. Not sure if it would work from 5.30.40 but its worth a try.
The general idea is that you have to find a firmware file that is a newer "version" than the one you currently have installed but does not have the downgrade restriction built into it. I think because it is a beta or test version or something like that.
So I started with 05.30.25 which wouldn't let me downgrade and I went:
05.30.25 ->upgrade to-> 05.40.01 (test version which allows downgrade)
05.40.01 ->downgrade to-> 04.31.20
I keep trying to update from 05.30.25 to 05.40.01 but it the install popup on TV is showing 04.31.20 and then gives me an error when trying to install.
IT FU* WORKED!!
Upgraded to 05.40.03, with the link you provided, and then downgraded to 04.30.50, UK version.
BLACKS ARE BACK!!
Am I in a good version though?
Got it to work aswell, installing 4.31.20 right now
Now just need to figure out how to block LG servers with the router provider from my ISP.
B6 in the uk won't update to this test firmware anyone in the uk got it working?
For the network upgrade/downgrade method you have to be very careful about following the instructions exactly or it won't work. You have to have the filename correct and put the exact file size into the "htdocs/<MODEL_NM>", etc...
Many many tks, it really worked.
I got back and installed 04.31.25 as I was missing the HDR Game Mode, but this time did it through a normal process using a firmware file in a USB pen drive.
I got 5.30.40 working on mine but I guess that is official firmware as I can't downgrade with it on my UK B6.
As garbb had suggested, install 05.40.03 ( http://su.lge.com/GlobalSWDownloadC....k2l-4303-05.40.03-prodkey_nsu_V3_SECURED.epk ), using the downgrade method (joey-astrologo/OLED55-65B6-Downgrade).
