Worked for me aswell, thanks :)

Litteraly just bought the mouse, downloaded ICUE to set it up and clicked the firmware update. It said the update failed and the mouse won't do anything now, it's not detected at all and no lights starts... Tried plugging it in different ports, to my other PC, nothing, just dead. Tried holding left+right click and then connect, dosen't do anything either....
