This screw needs to be removed next. This is what holds the left side of the entire back plate to the camera and if not removed will cause a major bend in the internal bracket.

Remove this silver screw next but keep it separate from the previous one.

This screw holds in the battery. Must be removed before the next one.

Last screw holding in this side plate. Removing this entire side plate will allow the main pcb to be removed easier later on. You can leave the side plate intact for now and come back to these screws later if you'd like.
