Chosen Solution
I’m trying to follow the Vita ‘replace the left joystick’ guide and ran into a problem - I can’t remove one of the screws on Step 1. I was able to remove the other 7 case screws, and even reach in to unplug the battery and touch screen cables, but… … I’m worried that I can’t just force it apart without damaging the right button board. What do I do?
Get a dollar-store eyeglass repair kit that contains those tiny screwdrivers. Select the best fitting one, and dip the point of the screwdriver into a drop of superglue (not so much that you end up gluing the damaged screw into the housing). Glue cheap screwdriver onto damaged screw, and when the glue has set, lefty-loosey and away you go.
