Safety precautions
Cracked glass preparation
- Apply strips of packing tape to the cracked glass until it's completely covered—this will help keep the glass contained and allow the suction cup to stick.
- Make sure there's a single strip of tape (not overlapping) across the bottom edge, big enough for a suction cup to fit on.
Remove the pentalobe screws
Mark your opening picks
Heat the bottom edge
Apply a suction handle
Screen bezel information
- There's a plastic bezel on the underside of the screen that sits on the frame. Insert your pick here, making sure it's completely under the bezel.
- There's a seam between the plastic bezel and the display panel. Don't insert your pick here or you'll separate the two, complicating the repair.
Insert an opening pick
- Pull up on the suction handle with strong, steady force until a gap forms between the screen and frame.
- Insert the tip of an opening pick in the gap you just created.
Screen information
- The screen and ambient light sensor cables are located near the volume and Action buttons.
- There are delicate spring contacts around the perimeter of the phone.
- The underside of the screen has thin, metal clips that go into corresponding slots on the frame.
Separate the bottom edge adhesive
- Slide the opening pick along the bottom edge to separate the adhesive.
- Leave the pick inserted under the bottom right corner to prevent the adhesive from re‑sealing.

Clean the frame
Repair step
- Use a lint-free cloth or a coffee filter to wipe in one direction along the perimeter of the frame to clean the adhesive residue.
Clean the screen
- If you're reusing your screen, apply a few drops of highly-concentrated isopropyl alcohol (over 90%) to a microfiber or lint-free cloth and wipe around the perimeter to prepare the surface for new adhesive.
Orient the replacement adhesive
- Without peeling any liners, lay the adhesive sheet over the frame to determine its proper orientation.
Apply the replacement adhesive
- Grab the tab in the corner of the adhesive sheet and peel the liner to expose a third of the adhesive.
Repair step
- Carefully align the exposed edge of the adhesive strip with the corresponding edge of the iPhone's frame.
- When it's correctly aligned, gently press the exposed adhesive strip onto the frame.

Repair step
- Use the pull tab to peel off the large front liner from the adhesive. The pull tab is often in a corner of the liner.
- At this point, you'll still have liners covering the perimeter. Don't remove these liners yet—they prevent the adhesive from accidentally sticking while you reassemble your iPhone.
