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.

Official online firmware (Russia). 
Ok

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?

What is your problem ? 
I have  a bright area in the middle of the screen after the update on 04.70.30.

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.
