Touch ID not working: Error 53

Very rarely does this happen but Every now and then on iPhone 6 or 6s we do a screen repair and it says the touch id will not work. All the cables are original just change the screen. I have replaced the home button cable and the button its self. The only thing I can find in my research is that the touch ID fail is part of the ERROR 53 security that it sensors the phone has been tampered and wipes its self of the touch id for security purpose. I have ordered OEM parts, and taken parts off phones left at my store and still wont work. The Only solution I can come up with is apple to maybe flash the software. I did over 300 repairs last month and 1 did it. Any input would be greatly appreciated!
