If present, use the spudger to remove the rubber screw caps over the 3 screws in the center of the backplate.

Start by removing the center 3 screws, which are shorter than the top 6 of the outer 10 screws.

Then, remove the outer screws, with exception of the bottom corner screws. Note: The bottom 4 screws are the same length as the center 3

Finally, remove the two bottom corner screws. The one on the bottom right should lift the cover, making it easier to insert the opening pick in the next step. However, you cannot remove the bottom right screw.

Yes, the bottom right screw is meant to catch the bottom panel to help lift the panel out. Do NOT drill the hole just to remove that screw.
