I was trying to disassemble my g900 and I successfully got 5 screws out of the 6 out but one of them I could not get out, even using multiple screw heads. I think I might have destroyed the screw by trying so many heads and trying to pry it open (I was desperate).. because now the screw looks more circular rather than hexagonal (or whatever it was). I'm afraid that i'm never going to be able to open it up. (I'm doing this to try and fix a touchscreen problem) Even if I go to a professional, I doubt they could open it up, using the same tools as I have?

Is there anything I can do? ANY help is appreciated

it looks as if yu might have to rip it out and then you might have to buy new case for the phone after
