I have an iPhone 5 with one pentalobe screw that would not just come out. It just spins in place no matter what I do. I tried supergluing a pin to it, but the screw is so small it won't stay. I tried soldering a small pin to it, but the surface area is so small the solder doesn't want to stay. I've tried several pentalobe screwdrivers, cheap ones, professional ones, metal ones, and yet I get nothing. Just the screw rotating in place. Is there anything I could do? It just sits there, rotating freely, mocking me. Any advice?
