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)?

 

Unfortunately the same problem for me and couldn't solve it. Any ideas guys?

Hey, the guy is me

Thanks guys and welcome to the club, dear smx.

Hi guys,

Yesterday i faced with this NSU_Emu by SMX method. Luckily, this method worked succesfully for my 49UF8507 model. I think NSU_Emu by SMX method can be an alternative way for who suffers from LgTvUpdater method like me and mtuna10. Finally my tv was downgraded. 

It's great hepmisafir, even more lunatics. 

 

I remember your post, but I forgot to answer. Sorry about that. Anyway, you see what is the situation with your UF850x. And I don't think so that different model number may cause downgrade problem. All the time I think the problem is in the wrong configuration of the connection between TV, PC and Internet/LG servers. If we are unable to connect to LG servers, wired connection between PC and TV without router will not help us. I also thought about it, the problem is only in fact that for me everything is working properly, so I can't see how it works for you.

you are probably right. Some guys argue interesting problems/solutions about similiar issues on this page:

http://blog.techflaws.org/2014/05/26/firmware-downgrade-for-lg-smart-tvs/

we hope to find a working solution. otherwise we will be cracked by the warranty terms. And i'm afraid we will not get new official update for a few years. 

No, it is rather not do anything. I thought that you might have set up one of these IP addresses. Automatic settings seems to be a good choice. 

 

I thought also about another modem and reset settings, but I'm afraid some of your health.    In the worst case we both go crazy, and maybe dtosun also be joining us. 

i'm still also with you guys   (Simon, i really appreciate your kind patience. thanks a lot!)

i have tried all possible ways too but still negative. One of the ways that i haven't tried is make an ethernet wired connection between PC and TV without router since i don't know how to do. And the last one of the ways is to learn russian to make our TV hacked by russian guys...

my last reply, fyi:

Well guys, I think that the name of TVs you both is HE_DTV_W15U_AFADABAA and that's why name isn't overwritten in in_dump file.

I updated LgDTVupdater, so please try again to downgrade your firmware and let me know. If it fails, we will try to do it locally.

I've tried your last update but still no changes in in_dump file. I perform the work by WiFi network.

- I set the area code for Russia as suggested by @mbabakj

- turned off windows 8.1 firewall (no antivirus soft.)

- checked for port 80 for apache.exe (also, AcrylicConsole.exe uses port 53)

- checked the gateaway if both pc and tv match (192.168.1.1)

Note:

Our Turkish UF8507 model number is different from Russia UF850V model. May this cause the problem? 

Hi SIMON,
