Several users posted before and after images of their TVs, showing a noticeable difference in picture quality after the update.

While some users have reported that the update has been pulled by LG, it is still available to download from the official LG website.

However, a new version of the firmware, v03.30.67, has been released in Korea, which reportedly fixes the brightness issue.

At the time of writing, the new firmware is only available in Korea, but users who are affected by the issue and do not want to wait can download it manually here.

According to another user, the firmware can be installed by updating it through a USB and following the instructions thereafter.

It is important to note that firmware updates can be risky, and there is a chance that they can cause issues with the TV.

Users who are not experiencing brightness issues with their LG C2 and G2 OLED TV after the firmware update may want to wait until the new firmware is officially released.

Stick around until then as we will update the story as the events unfold.
