Hello mixmar,
I managed to update my OLED 77C8LLA from 04.10.55 to official 05.10.02 downloaded from LG Korea.
Everything works fine except the TV does not recognize my IC module.
Turns out, I installed the “atsc” instead of the “dvb” version.
Strange that there was no warning of incompatibility during upgrade and all proceeded without a problem.
So know I want to revert back to correct previous 04.10.55 firmware which is impossible with C8 models.
Someone suggested to try the 05.10.03 version

Tried with the latest version of LgDTVUpDater 7/2019.
There is no firmware found.
Problem is in the answer file, which should be HE_DTV_W18O_AFABABAA.
Changing the answer file name to HE_DTV_W18O_AFABATAA works and the 05.10.03 firmware is recognized as “important software update” but installing doesn’t work
and sends message “Software update cannot be applied to the TV”.
Current values on my TV:
Area Option looks unchanged and is 3122
Continent index 50
Language&Country EU
HW Settings EU
Instart menu shows:
Country Group Code 4
Country Group "blank"
Country --
Area Option 3122
Device CN NG (in red text)
Any ideas how to fix this?
