What you need

Step 1

              Apply a heated iOpener

Power off your phone before beginning disassembly.
Use a hairdryer, a heatgun, or prepare an iOpener and apply it to the right edge of the back of the phone for about a minute to soften the adhesive underneath.

Step 2

              Insert an opening pick

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.

Step 11

Remove the back cover.
To install a 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.
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.
Alternatively, 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.
