My small tool kit bit for this size screw is too tapered, so I used my trusty little iFixit screwdriver. Problem is the screwdriver doesn’t provide enough grip area to remove this tenacious screw without stripping it. The screwdriver does have a hex at the end of the handle, which is 9/32” inch. Get a socket and handle, or even a 1/4” ratchet handle and you’ll have an easier time removing it.
The latches referred to are on the able connection block. The blocks are white, the latches are grey. Push the sides of the grey latches with any small flat screw driver or spudger.
While a little bit dangerous, I used an Exacto knife to cut through the adhesive. A slight rocking motion does the trick. Just be sure you don’t have a body parts between the knife edge and the hard surface you’re using to steady the mouse.
