A hard reset on the Oculus Quest 2 is a complete factory reset without using the companion app, which is particularly convenient when the headset does not respond or cannot be connected. When the headset is off, press and hold the power and volume-down buttons until you are at the boot screen. Swipe through to Factory Reset by means of the volume keys and confirm with the power button. The move deletes all stored data. This way, you can hard reset Oculus Quest 2.
