Updating the firmware

If you are using a FlexCord with your OP1 8K mod, we highly recommend to not use the extension cord. Simply plug in the FlexCord directly into your PC and update.

For mouse bungee user

We supply a silicone tube which is intended to be added to your FlexCord to make it fit in your mouse bungee. It can be hard to see since it's transparent.
