Angle a second opening pick upward and insert it at the gap where the bottom left corner of the back cover meets the triangular tip of the front cover’s left edge.

Push the pick up to get it above the overhanging lip in the back cover.

You'll see the plastic warp a little. This is normal.

While pushing upward, slowly rotate the pick towards the right edge of the camera until it's under the front cover.

The pick can slip out easily, so this may take a few tries.
