Downgrading isn`t allowed by default. I don`t remmember if anyone have success by downgrading your model.
Try to callibrate your picture first or perhaps reset of user settings (exit btn for >10 sec) can improve picture quality?

I experince the same problem after upgrading to this firmware, now the picture is way to bright even if brightness os set to minimum.
The before so beautiful picture quality is totally wanished.

Please tell me if you get any success by downgrading or anything else.

Thank you
