Firmware for the X3 Pro is delivered through the GameSir app over USB-C. Connect the controller to your phone, open the app, and apply any update shown. The app is also where you adjust the gyroscope, test buttons and tune sticks, so it is worth keeping up to date. Leave the controller seated for the whole flash.

FAQ

Can I update wirelessly?
No. The X3 Pro is wired only, so firmware goes through the GameSir app over USB-C.
What else does the app do?
