At this point, all of the screws holding the two halves of the case should be removed. Time to pry the bottom and top half of the case from each other

Don't be surprised if this takes a while. Also don't worry about being too gentle with the clips on the case - if they break, they will still be held in place by the screws we've just taken out

The first shot shows the area around the hinges - I recommend starting here. Just beside the left side of the battery I found it especially stuck... you'll probably need some heavy use of your spudger, just be cautious when using a screwdriver as it can bend the plastic permanently

Once the back is separated, just use your hands to pry from the sides. Move towards the bottom. Once at the bottom, pull north and it should separate the top case from the bottom half
