Try these removal methods:
Rubber Band Method – Put a rubber band in between the screwdriver and the stripped screw. This will give you a bit more grip and hopefully remove the stuck screw.
Super Glue Method – Put a small amount of super glue in the stripped screw. Hold your screwdriver on the screw for about 20 seconds and then try to unscrew it.
Small Flat Blade Method – You can also TRY to remove the stripped screw with a small flat blade screwdriver. Tilt the flat blade screwdriver at a 45 degree angle and try to get a grip inside the stripped screw head. Slowly and with pressure being put into the screw, turn counter clockwise.
