Disclaimer: The Galaxy Tab we acquired already had a shattered front glass panel. However, the procedure outlined in this guide is identical for both intact/shattered front panels.

Insert a plastic opening tool near the bottom left edge of the rear case.

Use your plastic opening tool to gently create a small gap between the front panel and the rear panel near the bottom left edge.

Run the plastic opening tool along the left side of the perimeter to create a bigger gap between the front panel and the rear panel.

Insert two guitar picks into the small gap created by the plastic opening tool.
