Any ideas guys? I would like to fix it

Hi, When you say that you smashed it, is it literally broken or did it just come apart? If it just came apart then here is a link to the Ifixit guide on how to replace the rumble motor in your controller. If you use it and reverse the procedure shown in the guide, perhaps it help you to restore the controller to its intact condition Xbox One Wireless Controller Trigger Rumble Motor Replacement
