      • Use tweezers or your fingers to peel off the old adhesive from the back cover and frame.

      • Use highly-concentrated isopropyl alcohol (over 90%) and a microfiber cloth to remove any remaining adhesive residue.

      • Follow this guide to apply new custom-cut adhesive.

      • If you're installing a new back cover, peel off the liners and press firmly around the perimeter to secure the back cover to the frame.
