• Extend theblue handlein a forward direction to secure the arms in a locked position.
• Rotate thehandlea full 360 degrees in a clockwise direction, or until you observe the cups beginning to expand.
• Confirm that thesuction cupsmaintain their parallel orientation. Should they exhibit signs of displacement, gently release thesuction cupsa small amount and reposition the arms.

• Employing warmth, utilize a iOpener by guiding it between the arms of the Anti-Clamp; alternative heat sources like hair dryers, heat guns, or hot plates are acceptable, however, exercise caution as excessive temperatures may compromise the display or internal battery.
• Position the iOpener in a folded configuration, ensuring it rests along the lower edge of the iPhone.
• Allow a sixty-second interval to permit the adhesive to loosen and establish a separation.
• Once the Anti-Clamp generates a noticeable gap, carefully slide an opening pick beneath the screen.
• Should the Anti-Clamp fail to produce an adequate separation, increase the heat applied to the area and rotate the handle by ninety degrees.
• Avoid exceeding a ninety-degree rotation per increment, and observe a sixty-second pause between adjustments; rely on the Anti-Clamp's pressure and time to facilitate the separation.
• Proceed past the subsequent three instructions.

The following three procedures detail the process of detaching the display assembly with the aid of a specialized tool.suction cup.

Applying heat to the bottom edge of the iPhone facilitates the loosening of the adhesive bonds holding the display in place, thereby simplifying the separation process.

A hairdryer can be utilized, or an iOpener can be employed, applying warmth to the lower edge of the iPhone for approximately 90 seconds to reduce the adhesive's tackiness.

• Position a suction cuponto the bottom portion of the front panel, situated directly above the home button's location.
• Confirm that the suction cupremains clear of the home button's area, because any overlap will obstruct the creation of a secure bond between the suction device and the front glass.

• Apply steady, forceful upward pressure to the suction cup to generate a minimal separation between the front panel assembly and the device's rear casing.
• Carefully slide an opening tool, or a similarly slender prying implement, into the newly formed gap, inserting it only a few millimeters.
• Due to the robust nature of the waterproof adhesive securing the display, establishing this initial separation requires considerable force; should you encounter difficulty, apply additional heat and gently oscillate the screen in an upward and downward motion to reduce the adhesive's strength, facilitating the creation of a sufficient gap for tool insertion.

• Utilizing a prying tool, carefully maneuver it along the phone's corner and upward along the left side, progressing in the direction of the volume adjustment buttons and the silent switch to sever the adhesive securing the display assembly.
• Pause your progress close to the upper-leftmost point of the display surface.

A fragile cable runs along the right side of your iPhone; avoid inserting your opening tool in this area to prevent potential cable damage.

• To release the adhesive, carefully reposition your tool at the lower-right edge of the iPhone, then maneuver it along the corner and upward along the right side, sliding to detach the adhesive.
• Exercise caution and limit the insertion depth of your pick to a maximum of 3 millimeters to prevent potential harm to the delicate display cable connections.

• Carefully elevate the display's lower boundary by applying upward force to the suction cup.
• Avoid lifting the display beyond an angle of15 degreesas exceeding this limit could potentially damage or sever the flexible cable assemblies that link the display to the device's internal components.

• To detach the suction cup from the front panel, grasp and exert force on the small protruding feature located on its surface.

• Carefully insert a prying tool beneath the screen's upper edge, working along the top to break the remaining adhesive seal.

• To release the retaining clips securing the display assembly, carefully move it downwards, positioning it further from the phone's upper border.

Initiate the iPhone's disassembly process by pivoting the screen upwards, originating from the left edge, mimicking the action of opening a book's cover.
Refrain from completely disconnecting the display assembly at this stage, because multiple delicate ribbon cables maintain its electrical connection to the iPhone's main circuit board.
Secure the display in an upright position using a support to prevent it from obstructing your work area during the repair.
