    • If the glass back is cracked, carefully tape over the entire surface with packing tape.

    • Apply a heated iOpener to the bottom of the phone for about two minutes.

      • You may need to reheat and reapply the iOpener several times to get the phone warm enough. Follow the iOpener instructions to avoid overheating.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the OLED display and internal battery are both susceptible to heat damage.

    • Apply a suction cup as close as possible to the bottom edge of the phone.

      • If the phone's back cover is cracked, the suction cup may not stick. Try lifting it with strong tape, or superglue the suction cup in place and allow it to cure so you can proceed.

      • Lift on the suction cup and insert an opening pick under the rear glass.

      • The rear glass very fragile and can break if you use too much force or attempt to pry with metal tools.

    • Once the pick is in place, reheat the edge with an iOpener for another minute.

    • Slide the pick down the bottom edge of the phone.

    • Go slowly so that the tip doesn't slip out of the seam. If sliding becomes difficult, reheat and reapply the iOpener.

    • Leave the pick in place to prevent the adhesive from resealing, and grab another pick as you proceed to the next step.

    • Insert another pick and slowly cut around the corner of the phone.

    • Due to the curved shape of the back, the glass is extremely fragile and prone to cracking in the corners. Be patient and reapply an iOpener if the corner feels hard to slice through.

    • Before cutting further, apply a heated iOpener to the long edge.

    • Repeat the previous heating and cutting procedure for the remaining three sides of the phone.

    • Leave an opening pick in each edge of the phone as you continue to the next to prevent the adhesive from resealing.

    • To reinstall the back cover:

      • First use tweezers to peel away any remaining adhesive from both the back cover and the phone's chassis.

      • Then, clean the adhesion areas with high concentration isopropyl alcohol (at least 90%) and a lint-free cloth. Swipe in one direction only, not back and forth. This will help prep the surface for the new adhesive.

      • Be sure to turn on your phone and test your repair before installing new adhesive and resealing the phone.

      • Replacement adhesive comes in a pre-cut sheet to match the exact contours of the back cover. If that's not available, you can use a high-bond double-sided tape, such as Tesa 61395. Be aware that this leaves gaps that are vulnerable to liquid intrusion.

      • After installing the rear cover, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond, such as by placing it under a stack of heavy books.

    • If desired, you may reinstall the back cover without replacing the adhesive. Remove any large chunks of adhesive that might prevent the back cover from sitting down flush. After installation, heat the back cover and apply pressure to secure it. It won't be waterproof, but the glue is usually more than strong enough to hold.
