Step 63 | Heat the back glass
- Warm the perimeter of the rear glass by applying heat with an iOpener, hair dryer, or heat gun until the surface feels warm.
- To ensure a strong seal, apply consistent pressure across the entire edge of the rear glass; for enhanced adhesion, utilize screen vise clamps if available, otherwise proceed with alternative securing methods detailed below.
Step 64 | 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 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.
Employ an object approximately the dimensions of a standard iPhone in height and width, but exceeding the box's side walls in vertical length. Position this object atop the iPhone, then add several substantial weights on top of it.
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 arrangement overnight.
Step 65

- Position the iPhone on a level, non-abrasive surface with the display facing downward.
- To prevent damage to the rear glass surface, affix masking tape across its exterior.
Step 66
- To ensure consistent separation, position flat, uniform items—such as coins—at regular intervals along the tape's perimeter, abutting the rear glass.
- Ensure the combined thickness of the shims creates a uniform elevation exceeding the camera module's protrusion.
Step 67
- To apply downward pressure evenly across the iPhone's surface, position several books or a similar weighty item on top of it.
- To avoid marking or damaging delicate surfaces, use only inexpensive materials as a base.
- Allow the components to remain undisturbed for a minimum of thirty minutes; reduce the required time if the items are heavier. For optimal results, maintain the stacked configuration overnight.
