Model O 2 Wired - Firmware Update

Before you get started

Before using your new mouse for the first time, it is required that you update its firmware to get the best performance. 

It's also essential to download and install the latest version of Glorious CORE. You can find a download link for the software here. If CORE is already installed on your computer, click on its settings icon and then click the "Check for Updates" button. The software will notify you if there's an update available.

You need CORE version 1.0.33 or higher to be able to perform the firmware update.

Proceed only if the firmware version you see on the mouse's device screen in CORE shows v2043. If you see v1.0.4 or a higher 1.0.X combination, congratulations! Your firmware is already updated!
