3D button as Capture button

hi
how to make 3d button to funtion as capture button on stock camera instead switching 3D/2D mode?
i tried changing generic.kl etc but still no luck
i'm using last XBSA V3D (thank you XBSA) ROM which based V30c that don't use 3D button as capture button like V30A

OT : is somebody know why XBSA ROM thread is closed?

thank you
