Opening 2GIG GC2 Panel

I need to update the firmware and install a new cell module in my 2GIG GC2 panel, but I am having difficulty taking out the top screw in order to open the panel. The screw is partially stripped and it is hard to get a good angle using a screwdriver since it so close to the wall. Is it possible to open the panel without taking out the top screw? If not, any thoughts on how to remove the screw? I’ve tried using a rubber band and currently have a screwdriver superglued to the screw and am planning to wait until tomorrow to let it cure more before trying to remove it.

Is it possible to open the panel without taking out the top screw?

Not without breaking the plastic around the screw.

Stripped screws are no fun, especially smaller ones that are hard to drill out.

Have you tried a precision extractor kit?
