iphone 5s Damaged motherboard when replacing Display Connector Shield

Hi:

When I replaced the Display in my iphone 5s I reinstalled the connector shield puting the wrong screws in place... I placed the 1.7mm screw where there should have been a 1.2mm screw. Now the phone will not boot or restore and I read the long screw caused the damage. Is there anythng I can do to repair the damage?

Thanks-
