• To establish the correct positioning of the adhesive sheet relative to the frame, place it on the frame's surface, utilizing the camera opening and the markings on the upper and lower borders as visual references to ensure proper alignment.

• To reveal a portion of the adhesive, carefully lift the corner tab of the liner and remove it, exposing approximately one-third of the adhesive surface.Exercise caution, as the newly exposed adhesive possesses a high degree of tackiness; avoid unintended contact with other surfaces until application to the frame is prepared.Should your adhesive product incorporate multiple liners, prioritize the removal of the liner that directly exposes the adhesive intended for bonding to the frame.
• The adhesive's inherent stickiness demands careful handling to prevent premature adhesion to unintended materials.
• Prior to application, ensure the adhesive remains free from contact with any surfaces to maintain its bonding capabilities.

• Ensure the visible border of the adhesive strip is precisely matched to the matching edge on the iPhone’s casing.Because the adhesive permanently bonds upon contact, repositioning is impossible; any misalignment necessitates removal and replacement with fresh adhesive.Correct alignment requires meticulous attention to detail before proceeding.
• After verifying proper positioning, apply gentle pressure to secure the adhesive strip to the iPhone’s frame.The adhesive strip's surface should make firm contact with the frame's surface during this step.Avoid shifting the adhesive strip once contact is made to prevent bonding errors.

• Carefully remove the adhesive backing, ensuring firm contact between the adhesive and the surface.
• Proper alignment of the adhesive is indicated by a seamless fit of the edges within the frame's boundaries.
• To correct minor positioning errors, delicately reposition the longer sides of the adhesive to match the frame's contours.
• Should the adhesive develop folds or creases, discard it and apply a new set for optimal results.
• In the absence of replacement adhesive strips, the iPhone can be reassembled and used; however, be aware that its water resistance will be diminished until a new adhesive seal is applied.

• Employ a spudger to apply pressure to the adhesive securing the iPhone's edges.
• Exercise caution near the delicate grounding clips; should one become displaced, carefully restore its position using your fingers or tweezers.
• Avoid excessive force, as it may cause the adhesive to extend and lose its original shape.

• Employ a spudger or manual dexterity to disengage the pull tab affixed to the extensive front liner, typically located within a corner.
• Utilize the pull tab to detach the expansive front liner from its adhesive backing.
• Remaining liners may still protect the outer edges, safeguarding the adhesive during reassembly; refrain from removing these smaller release liners at this stage.

To facilitate access, carefully support the rear glass component by applying pressure along its right-hand border.

To establish the electrical connection between the rear glass connector and the main circuit board, apply pressure using either a fingertip or the broad, planar edge of a specialized opening tool.

Proceed to step 46: Secure the battery press connector to the logic board by applying pressure with a finger or a spudger.

• Prior to final reassembly, it's advisable to verify the functionality of the repair; activate the iPhone and confirm normal operation.Following the operational test, deactivate the device and proceed with the remaining reassembly steps.Should the iPhone fail to power on, establish a connection to a power source and attempt startup once more.

1. Employing either your fingertips or a specialized spudger, carefully detach the surrounding protective liners to reveal the underlying adhesive.
   During liner removal, prevent any contact between surfaces and the newly exposed adhesive to maintain its bonding properties.
   Thoroughly inspect both the device frame and rear glass, eliminating any detached liner fragments to guarantee a completely clean adhesive surface.

1. Position the rear glass component onto the device frame, initiating the alignment process from the uppermost boundary.
   Should you encounter opposition during installation, a surrounding retaining clip might be deformed and compressed by the frame; carefully examine the area of resistance and delicately restore any bent clips to their original shape.
   Apply even pressure across the iPhone's borders to ensure the rear glass makes complete contact with the frame.

Employing a hair dryer, heat gun, or iOpener, apply warmth to the outer edge of the rear glass.Continue heating the perimeter until the surface temperature reaches a point where it's uncomfortable to briefly touch.This thermal application reduces the adhesive's viscosity, facilitating a more secure reattachment.The purpose of this process is to weaken the adhesive bond, not to damage the glass itself.
Increased warmth allows for improved adhesion during the reassembly procedure.

1. Employ your fingertips to apply consistent, strong pressure encompassing the entire outer edge of the iPhone's casing.

1. Position the iPhone with its display facing downwards onto a pristine, level workspace.
   Apply a continuous adhesive strip along the outer edge of the rear glass to safeguard its cosmetic appearance.
