You can download QMK toolbox from the github here (I recommend insalling all drivers when the option is presented)
You can download VIAL from the official site
the .bin file can be grabbed here
(Another third party flash option: https://github.com/thompson-vii/kb16_rev2_vial_fw )
Open QMK toolbox and point to the .bin file on your local machine, it will most likely be in your downloads by default
Unplug your macro pad and hold down the top left corner key while plugging it back in and hit flash while holding the key down, you should then see QMK toolbox display the follwing, once that's complete you can close QMK toolbox and unplug then plug the macropad back in, it should light up with the default rainbow pattern
