Lay a hot iOpener along the bottom left corner of the iPad, spanning from the opening pick to the home button.
After letting the adhesive soften, insert a halberd spudger into the iPad next to the opening pick.
Cut the adhesive along the bottom left side of the iPad using the halberd spudger. This may require reheating the edge of the iPad.
Continue to slide the halberd spudger back and forth to ensure most of the adhesive is separated.
