Note: If you’ve already completed the removal steps, skip to reassembly.
Removal
Use a torque driver and the PL1.1 bit to remove the two back glass PL1.1 screws, one from each side of the USB-C connector.
Use the heated display removal fixture to heat the adhesive and open the back glass.
Refer to the Heated Display Removal Fixture Operations Manual for instructions.
Caution Only cut the bottom of the iPhone while it's in the fixture.
Don't tilt the back glass more than 5 degrees while cutting or opening it.
Remove the iPhone from the heated display removal fixture and place the iPhone in the repair tray with the back glass faceup and the USB-C connector facing the cutout.
Insert the edge of the adhesive cutter between the back glass and the enclosure.
Hold the adhesive cutter at a 45-degree angle. Cut along the sides until you reach the height of the antenna band.
Slide the back glass toward the bottom of the iPhone until you see a slight gap. Insert the adhesive cutter at a 45-degree angle into the top of the iPhone and cut along the top until the back glass is free.
- Caution: To avoid damaging the flex cables, don’t tilt up the bottom of the back glass more than 5 degrees.
Insert the repair tray suction cup into the slot in the repair tray.
Tilt up the back glass and secure it to the suction cup. Covering the camera with the camera cap is recommended to prevent contamination.
Note: Wearing nitrile or lint-free gloves is recommended when covering the camera.
- Caution: Don’t damage the flex cable as you tilt up the back glass.
- Warning
If the battery is dented, punctured, or otherwise damaged, stop the repair. You can find a service option at support.apple.com/repair.
If the back glass is broken, inspect the enclosure. If there are shards of glass in the enclosure, put on safety glasses with side shields and cut-resistant gloves. Use ESD-safe tweezers to remove the shards. Then use ethanol or IPA wipes to remove any remaining shards from the adhesive on the perimeter of the enclosure. Vacuum any shards of glass from the workspace.
Use a torque driver and the trilobe bit to remove two trilobe screws from the battery connector cowling. Remove the cowling and save it for reassembly.
Lift the end of the battery flex cable off the connector (1). Then lift the end of the the back glass flex cable off the connector (2).
- Caution: You must disconnect the battery flex cable first to ensure that the iPhone stays turned off.
Hold the back glass by the edges. Pull the tab on the suction cup to release it from the back glass. Then set the back glass facedown on a clean, flat surface.
Reassembly

Remove the suction cup from the repair tray.
Use the adhesive removal tool or the black stick to lift the adhesive from the enclosure. Use ESD-safe tweezers to pull the adhesive. Repeat this process until all the adhesive is removed from the perimeter of the enclosure.
- Caution
Only use the adhesive removal tool as instructed. Avoid contact with plastic parts of the enclosure.
Don’t touch the camera assembly, grounding springs, or nearby parts.
Use ethanol wipes or IPA wipes to clean all residual adhesive from the edges of the back glass and the enclosure.
- Warning: Inspect the enclosure for loose or extra screws and small parts, which can damage the battery and cause safety issues.
Align the replacement back glass adhesive over the enclosure starting at the bottom edge.
- Caution: Ensure that you’ve removed all adhesive residue from the back glass and the enclosure before you apply the replacement back glass adhesive.
Important: If you’re installing a replacement back glass, peel the protective liner from the top and underside of it.
Inspect the back glass adhesive. If the adhesive is positioned correctly on the shelf of the enclosure, continue to step 6. If the adhesive isn't correctly positioned, repeat reassembly steps 2 and 3 to remove it. Clean the shelf of the enclosure if necessary. Then repeat step 4 with a new back glass adhesive.
Use the flat end of the black stick to adhere the back glass adhesive to the enclosure. Move the black stick around the edge of the enclosure at least three times to ensure that the adhesive is adhered evenly.
