raiju ultimate ps4

my x button stopped working so re mapped it to one of the extra buttons on controller and that didn't work either tried on all 4 extra buttons but still no response yet they work for circle, square and triangle when I re map them, anyone know how to fix  iv tried pretty much everything with no success, it is out of warranty hence why I asked here,  I made sure ps4 was up to date, I tried switching to different presets within the app to map buttons for controller, reset controller through app
