Playstation 4 Controller Shell Replacement Guides
There are two main variations of the PS4 dual shock controller. The v1 and v2. The V2 version has the lightbar that shows through the touchpad.
V1: JDM-010, JDM-020, JDM-030
Inside these shells is a screw pin that holds the boards to the front shell, this pin needs to be removed from the front shell for it to fit the jdm-030 version controller, this pin is not essential- once the controller is put back together everything is held together and in place securely.
V2: JDM-040, JDM-050, JDM-055
