Screws stripped, cannot replace back panel
I stripped my screws when attempting to repair my back panel of my phone and now I can't get them out at all. I've tried the rubber band method, the glue method, and I attempted to cut a small part of the screw to use a small flathead but I wasn't able to find anything small enough to cut it without damaging the phone, as you can see.
I've got the tools for it as well as new screws. The screws were the 5-star ones, I think those are pentalobe not 100% sure on that but I have both screws.
Below are images of how badly the screws are stripped. Do you guys think I'll be able to get it fixed?
