You can get the back plate on and off by feel alone. To put the backplate back on, it snaps on, and you can feel the screws with your fingers, and then use a finger nail to work out what angle the slot is at. Then you can feel the end of the screwdriver between finger and thumb, and aim it at the slot and move it around a millimetre at a time until it falls into the slot. Then turn to the right until you feel a little bit of resistance. To take it off, feel the screw with a finger and find the direction of the slot with a finger nail, feel end of screwdriver between finger and thumb and aim it at the slot, move it around a millimetre at a time until it falls into the slot, and turn to the left until you hear a click. To lift up the back plate, feel along the edge of the back plate near the L/R buttons to find the cut out sections. Have the console with the back facing up and put the poky part at the end of the stylus into the cut out part with the round part facing down. Hold the console with your thumb above the cut out part, your middle finger underneath and your index finger/palm holding the stylus. Lever the stylus down, which will make the backplate pop up. Same on other side. Hold both cut out parts and lift up.
