Hey boss, dunno if it would work for you but I was in a similar boat as you recently. Purchased the mouse, and upon initially plugging it in everything seemed fine until I installed the Armoury software and ran the firmware update. After it "successfully finished", the mouse no longer had any lights, scroll wheel functionality was reversed, wireless mode was completely unresponsive ect. I tried every version of Armoury I could find for updating and firmware update always said it succeeded but would remain on old version with software saying No ROG Device detected. What finally brought the mouse back to life was docking it, while unplugged, into the wireless receiver/charger. Soon as it made contact the lights came back on, software detected the mouse, and firmware showed correct updated version with no updates available upon checking. Don't know if same issue you're having but if you haven't tried docking the mouse in the receiver might be worth a shot. I spent hours troubleshooting before trying that on a whim assuming the mouse being plugged in would trump it being docked smh
