Apply a suction handle to the back cover.
Lift with a suction handle to create a gap between the back cover and the frame of the phone.
Insert an opening pick into the gap.
If the glass is badly cracked, cover it in packing tape to create a surface for the suction cup to adhere to.
If the adhesive won't budge, apply more heat, not excessive force. Too much force could break the glass.

Note that there is more adhesive along the top edge and around the camera bezel than around the rest of the phone.
Cut carefully around the left edge near the fingerprint sensor or you risk damaging the ribbon cable inside.
If, at any point, the adhesive feels stubborn, apply more heat—not more force.

Remove the back cover.
To re-install the back cover:
Use tweezers to peel away any remaining adhesive from the phone's chassis. Then clean the adhesion areas with high concentration isopropyl alcohol (at least 90%) and a lint-free cloth to prep the surface for the new adhesive. You don't have to clear out adhesive down to the plastic but larger pieces should be removed.
Turn on your phone and test your repair before installing new adhesive and resealing the phone.
Carefully apply the new adhesive to the back cover, then line up one edge of the glass against the phone chassis and firmly press the glass into the phone.
