The X4 Aileron has no single factory-reset button, so a reset combines clearing the Bluetooth pairing, re-syncing the two halves, and recalibrating. Forget GameSir-X4a in Bluetooth and re-pair, long-press Share or Xbox to match the RGB rings, and recalibrate triggers with LB + Xbox + RB followed by three full trigger pulls. The GameSir app can restore defaults if needed.
