Besides the screws we removed already, the bottom cover uses 4 plastic tabs (two tabs on the front of the device and two on the sides).
Pry the plastic tabs to remove the bottom cover.
It shouldn't require much force to open the cover once the screws are removed (I broke one of the tabs trying to open the device with the middle screw still in place).
