- Carefully align the glass with the frame, then 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 53 | Heat the back glass
- Employing a heat gun, warm the perimeter edges of the rear glass to facilitate adhesive adhesion.Use a specialized iOpener tool to gently apply heat around the perimeter of the device's casing.Apply heat from a hair dryer or heat gun to the surface until its temperature reaches a point where it feels hot when touched.
- Apply consistent, even pressure encompassing the entire edge of the rear glass.
- 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 54 | Press the back glass
- Ensure uniform pressure during iPhone reassembly and secure the rear glass to the frame by carefully considering the camera module's protrusion.
- Using the iPhone's original packaging, position the lid on a level surface.
- Because the original packaging is not required, proceed to the alternative procedure.
- Position the iPhone, camera lens facing upwards, within the box’s lid, ensuring the camera bump aligns with the designated indentation.
- Use an object approximately the size 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 their weight necessitates a longer waiting period. For optimal results, maintain the stacked position overnight.
Step 55
Lacking the original iPhone packaging, use the subsequent three steps to achieve uniform pressure on the rear glass.
- 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 56
- Use flat, rigid items—such as two coins of comparable thickness—and position them directly against the tape's perimeter, aligning with the rear glass edges.
Arrange the coins to ensure uniform coverage and that their thickness matches or exceeds the height of the camera protrusion.
Step 57
- To apply downward pressure evenly across the iPhone's surface, position several books or a similar weighty item on top of it.
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; lighter objects benefit from a longer waiting period, and overnight retention is the preferred duration.
Step 58 | Install the pentalobe screws
- Employ a 3/8-inch socket wrench to loosen the retaining bolt, ensuring you apply consistent pressure to prevent damage to the threaded shaft and observe the torque specification of 12 Nm, and be aware that the spring clip may dislodge during this process.Use a P2 driver with a pentalobe tip.Secure the pair using the specified fasteners.Screws, each measuring 7.7 millimeters in length, are required.Flanking the charging port are components located on both the left and right sides.
