Did you try 4.70.70?

  •  (rename to starfish-dvb-secured-k3lp-573.drto.k3lp-57322-04.70.95-prodkey_nsu_V3_SECURED[0].epk)
  •  (rename to )

I see no difference between .45 and .55. So I think the slowdown is due to something else.
Probably is better if you reset to factory settings.

Version 4.80.72 is a downgrade to a verision similar to 04.70.70 of May 2018.

Version 4.80.95 and 4.70.95 are the same firmware.

[mention=17383]murattkn3[/mention] all software is the same for ALL... it's the platform which is important.. yours and mine is k3lp every epk with "k3lp" in it will be ok.

can we throw these software through USB

Sure.. put the epk in an usb pendrive under the directory LG_DTV  and it will update if the version is higher than the actual one.

Thanks for sharing, however it says on my tv that It cannot be downgraded. Like It just won't apply yet I've followed every step and a factory reset won't do the trick either. I've done factory resets about 8 times now without any success or more. Also since my tv is a 2017 model, I highly doubt that it can be downgraded as I've read. It is probaly locked in the firmware, so hopefully somebody will find out a bypass for this anytime soon. 

officially it can't be downgraded.
Unofficially, I am the only one able to do it without hacking the TV and without setting up a fake server or anything :P
Believe it or not...

      Hi all,
      My LG OLED55E7N just updated to firmware 06.00.25. I must have wronged the god of Google, because I fail to find any whatsnew. Anyone?

      From heart rate monitors in smartwatches to accelerometers and gyroscopes for measuring an athlete’s movement or swing, technology takes sports to a whole new level of precision. In the world of esports, advanced tech isn’t just something that’s good to have, it’s a necessity. And in this world, LG UltraGear hardware has developed a reputation as the best gear for victory.

      According to , the gaming PC and monitor market expanded rapidly in 2020, reaching 55 million units sold for a year-on-year increase of 26.8 percent. And with more people than ever working and playing from home, demand for better PC hardware experienced huge growth with sales of LG’s gaming monitors more than tripling between 2019 and 2020.
      Let’s take a look at what sets LG UltraGear gaming monitors apart from the rest.

      Compared to other panel technologies such as Twisted Nematic (TN) or Vertical Alignment (VA), LG’s In-Plane Switching (IPS) panel provides a wider viewing angle with minimal color distortion as well as a wide color gamut with excellent contrast. LG was the to introduce an IPS monitor with one millisecond Gray-to-Gray (GTG) response time, a significant advantage over the 20-30 milliseconds of regular monitors. One millisecond means fewer distracting visual effects such as ghosting for a smoother, faster gaming experience. And with a refresh rate of up to 144Hz, ultra-high screen resolution and exceptionally lifelike picture quality, it’s easy to see why LG UltraGear has become an esport favorite.

      Currently there are in the UltraGear monitor lineup including a new 32-inch (model 32GP850) featuring the advanced Nano IPS display technology. Later this year, LG will debut the industry’s first 34-inch monitor with NVIDIA G-SYNC® ULTIMATE built-in for the highest level of compatibility with NVIDIA graphics cards.

      LG makes a great effort to understand what gaming fans really want. One way is through the UltraGear Advisory Board, an online community of approximately 200 gamers from around the world managed by LG. Members of the board have a voice in developing new products, advising on both technical as well as design aspects.

      And LG UltraGear gaming monitors are not only the ideal choice for a home gaming setup, it’s a brand in high demand by professionals who game for a living. LG is currently with Gen.G Esports, one of the top esports organizations, to support their League of Legends Champions Korea (LCK) team. Using LG UltraGear monitors, the team is already .

      Built for a better gaming experience to deliver an edge over the competition, LG’s UltraGear gaming monitors have been the preferred gear for many gamers since its launch in 2018. So whether you’re a pro gamer or just a casual player, LG UltraGear can provide the right gear for the job to make the difference between victory and defeat.

      Hi LG
      When playing a Dolby Vision file encoded in MKV container format, the image is green/purple in colour. A quick googling says, this occurs due the default media player in WebOS not able to decode Dolby Vision MKV container files properly.
      When will this be fixed?

      Hallo, I bought a 55un74006LB smart tv in Italy. It seems not to have usb recording capabilities, according to the information on the italian website, but the UK site declare it has. I think it's the same product with the same functions, so how can I turn the live tv and usb recording on? I think I found the options in the service menu but I cannot change the values. Any suggestion?

      We have signage projects, all over GCC. 
      We are facing issue with Webos tv especially on model 49sm5ke-bj. It is losing connectivity overnight, the displays are left switched on at stores. But on the next day it wouldn't be connected to the Internet and hence the contents are getting corrupted. Always we need to restart the display again or exit and start the app again.

      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 10. 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 IC. I shocked why with a simple change in one of the TV parameters, everything is got complicated. 
      In details, here is the picture of the parameters currently set on the LG TV with the model number of 49LH549V-TD: 

      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.
      Best regards
