tobie91192 teaches you how to take apart an XBox 360 controller to change the cover. First, take out the battery pack on the back. Use a flathead screwdriver to remove all seven of the screws on the back of the controller. It's 2.0 mm. Once you take out the screws, place them in a pile so that you don't lose them. Remove the back of the controller and proceed to take out the grey plastic bottom part. Next, remove the buttons in the back. Then carefully remove the mechanism on the inside and you can change the cover on the controller.
