hey guys im really stuck and really need help with my n900 last week i broke the lcd so i bought a new lcd when i was opening my n900 i got stuck on one screw that would not open after hours of trying to open this one screw i rounded it and it no longer gripped onto my screwdriver i tryed sticking a screw with superglue but that failed too. please please help me on what i should do now i was thinking if i were to force the back of the lcd panel off would i be able to purchase that part or not because it is only one screw stopping me from replacing the lcd

thanks in advance
