To perform a factory reset:
Locate the small Reset hole on the back of the controller (near the M1 / M2 buttons).
Insert a pin, paperclip, or SIM ejector tool into the reset hole.
Hold for 5 seconds until the controller resets — the LEDs will flash briefly.
After the reset, all previous pairing data is cleared. You will need to re-pair the controller with your device from scratch.
