Stripped backplate screw is now slight broken
I'm trying to remove my vita's backplate and managed to strip one of the screws. First I used a rubber band, nothing happened. Then I went to super glue and that only gunked up the hole. After hours of trying I got a micro dremel and carved a line into the sides of the screw. I inserted the Philips head, turned and a piece of the screw broke off.
Now I have a stuck, stripped screw with half of its top broken and a cavity gunked with super glue.
Is this screw determined to be lodged forever?
