Instructions
Unplug the controller from the Xbox console.
Flip the controller over and remove the seven screws on the back of the controller with the Phillips screwdriver. Each hand grip has two screws, with two more located under each shoulder button. The remaining screw is located under the silver Xbox sticker.
Lift the controller faceplate to reveal the inside of the controller. Set aside loose buttons for when you reassemble the controller.
