Those Phillips are JIS Phillips standing for Japanese Industral Standard. These Phillips are different than the American Phillips and its thread locked.
So if you want to remove those screws you need, I believe #2 JIS screwdriver. If you stripped it because you had the wrong tool. Good luck. May have to slice a slot in the head of the screw to get them out.
