GameSir recommends checking the GameSir app for firmware updates before you play. Charge both halves, connect over USB-C (more reliable for flashing) or Bluetooth, and apply any update shown. Do not power off or disconnect mid-update; the controller often needs to be re-paired or recalibrated afterward.

FAQ

Should I update over cable or Bluetooth?
Either works, but a USB-C connection is the most reliable for firmware flashing.
Do I need to re-pair after updating?
Often yes. Re-pair and recalibrate if the controller prompts you after the update.
