Storia per "How to remove stripped screws?"

Hello,  I am trying to replace a battery on the moto z play phone.  I got the back off and screen separated.  But can not get the little screw out to remove the metal piece holding the battery cord in place.  Anyone have a suggestion on removing stripped screws?  I have tried the rubberband trick but no luck.
