Insert the point of a spudger into a groove at the bottom of the motherboard.

Gently pry up to loosen the motherboard from the frame and from the edge clips.

Use a spudger to move any flex cables out of the way, as well as making sure that any modules attached to the motherboard (such as the front-facing camera) are loose from the frame.

If you feel any resistance, stop. Make sure there are no components still holding the frame to the motherboard.

Lift the motherboard up from the frame and remove it.
