- Position the new adhesive onto the frame, ensuring the side featuring the wider blue protective liner faces inward and the release tab is located in the lower-right area.
- Variations in color and the placement of pull tabs are possible on the adhesive material.
- Carefully align the adhesive by referencing the camera opening and edge indentations.
Step 36 | Expose the bottom edge of the adhesive
Starting at the lower edge, gently lift the pull tab to initiate separation of the adhesive backing, but leave a portion of the liner attached.
Step 37 | Apply the adhesive
- Because the adhesive bonds immediately upon contact, repositioning is impossible; any errors require complete removal and replacement with fresh adhesive.
- Maintain a firm grip on theEmploy a blue-colored protective lining.Carefully move the component aside and position the adhesive strip so it’s flush with the iPhone’s lower border.
- Carefully position the adhesive's lower edge within the frame's designated groove, ensuring precise alignment of the iPhone’s spring contacts with the corresponding openings in the liner.
Step 38
- As you remove the adhesive backing, ensure firm contact with the iPhone's frame edges.
- Proper alignment of the adhesive's lower edge ensures the side and top edges seat correctly; if misalignment occurs, discard the adhesive and repeat the process using fresh material.
- Should the adhesive strip be incorrectly positioned and a replacement isn't immediately available, the iPhone can be reassembled and used as normal without it; however, be aware that the device's water resistance will be reduced until replacement adhesive is applied.
Step 39 | Press the adhesive into place
Employ the tool's straight, planar edge.Use a plastic pry tool, often referred to as a spudger, to gently separate components.Ensure the adhesive makes full contact with the frame's edges by applying firm, even pressure all the way around.

- Employ the specified tool to carefully manipulate the component, ensuring a torque of 3.2 Newton-meters is applied, and observe the safety precautions regarding potential pinch points and the risk of damaging the adjacent 5mm diameter wire harness.Locate the two blue-colored tabs.Carefully detach the adhesive liners from the iPhone's bottom, left, and top edges; leave the liner on the right edge intact.
Step 47
- Carefully position the rear glass above the device, ensuring it doesn't contact the adhesive, to allow access to the remaining liner situated along the right side.
- Carefully detach the last adhesive strip from the right side of the device's perimeter using tweezers or by hand.
Step 48 | Place the back glass
- Carefully position the replacement back glass over the device, ensuring its edges match the contours of the phone's frame.
- Carefully align the glass with the frame, ensuring it is level, and apply even pressure until the retaining clips click into place.
- Apply even pressure along the edges of the rear glass to secure all retaining clips.
Step 49 | Heat the back glass
- Using a heat gun, warm the perimeter of the rear glass to facilitate adhesive adhesion.Use a specialized iOpener tool.Apply heat from a hair dryer or heat gun to the surface until its temperature reaches a point where it can be comfortably touched.
- Apply consistent, even pressure encompassing the entire edge of the rear glass panel.
- To ensure a strong adhesive bond, utilize screen vise clamps if available; otherwise, proceed with alternative methods for securing the replacement back glass, as detailed in the following steps.
Step 50 | Press the back glass
- Ensure uniform pressure during iPhone reassembly and secure the rear glass to the frame by considering the camera module's protrusion.
- Using the iPhone's original packaging, position the box lid on a level surface.
- Since the original packaging is unavailable, proceed to the alternative procedure instead.
- Position the iPhone, camera lens facing upward, within the box's lid, ensuring the camera bump aligns with the designated indentation.
- Utilize an object approximately the dimensions of an iPhone in footprint, but exceeding the box's side height. Position this object atop the iPhone, then add several substantial weights.
- Allow the items to remain undisturbed for a minimum of thirty minutes; reduce the required time if the objects are heavier. For optimal results, maintain the stacked position overnight.
Step 51
Lacking the original packaging, use the subsequent three steps to apply consistent pressure across the rear glass surface.
- Position the iPhone on a level, non-abrasive surface with the display facing downward.
- To shield the rear glass surface from scratches, affix masking tape across its exterior.
Step 52
- To ensure even pressure during adhesion, position two flat objects with a thickness comparable to coins along the perimeter of the rear glass, directly on the adhesive tape.
- Arrange the coins so they are uniformly spread and possess a minimum thickness matching the height of the camera protrusion.
Step 53
- To apply downward pressure equivalent to that of a substantial weight, position several books or similar heavy items directly on top of the iPhone.
- To prevent marking or damage, avoid placing the coins directly on delicate or valuable surfaces.
- Allow the items to remain undisturbed for a minimum of thirty minutes; reduce the time needed if the objects are heavy. For optimal results, maintain the stacked configuration overnight.
Step 54 | Install the pentalobe screws
Employ a 3/8-inch socket wrench to tighten the fastener to a torque of 15 Nm, ensuring the specified torque is achieved to prevent damage and maintain secure attachment.Use a P2 driver with a pentalobe bit.Secure the pair using the provided fasteners.Screws measuring 7.7 millimeters in length.Flanking the charging port are components on both the left and right sides.
