• Deactivate the iPhone's power supply by turning it off before you start taking it apart.
• Using a 3.5 mm pentalobe screwdriver, extract the pair of screws located on the iPhone's lower edge.
• Separating the iPhone's display assembly will irreversibly damage its water resistance capabilities; therefore, acquire replacement sealing components beforehand, or exercise extreme caution to prevent moisture ingress if you intend to reassemble the device without new seals.

• To avoid potential harm to your device, ensure the opening pick isn't inserted beyond its intended depth; this procedure details how to mark the pick to safeguard against such damage.
• Determine the measurement of3 mmfrom the pick's leading edge and use a permanent marker to create a visible indication on the opening pick.
• For enhanced precision, consider marking the other corners of the pick with varying measurements as well.
• As another option, affix a coin to the pick's shaft,3 mmaway from its tip.

• To mitigate additional damage and potential injury when addressing a cracked iPhone display, secure the fractured glass with adhesive tape.
• Apply multiple layers of transparent packing tape across the iPhone's screen surface, ensuring complete coverage of the entire front face.
• Always utilize eye protection, specifically safety glasses, to guard against glass fragments that may become dislodged during the repair process.
• Should the suction cup fail to maintain adhesion during subsequent steps, create a handle by folding a robust tape, like duct tape, and employ it to gently elevate the screen.
• As a last resort, secure the suction cup to the screen's surface using superglue to facilitate lifting.

• The following three actions illustrate the function of the Anti-Clamp, a specialized tool developed to simplify the initial opening process; should you choose not to utilize this tool, proceed to the steps located three sections later for an alternative approach.
• Detailed instructions regarding the Anti-Clamp's operation are available in a separate, dedicated guide.
• Grasp theblue handleand move it in a rearward direction to disengage the Anti-Clamp's securing arms.
• Carefully position the arms across either the left or right side of your iPhone’s frame.
• Place the suction cups close to the lower edge of the iPhone, situated directly above the home button—one on the front surface and one on the rear surface.
• Apply pressure by compressing the cups together to establish a secure suction bond to the intended area.
• Should the iPhone’s surface prove excessively slick, preventing the Anti-Clamp from maintaining a firm hold, applying adhesive tape can provide a more textured interface for improved grip.

• To engage the locking mechanism, draw theblue handlein a forward direction.
• Rotate thehandlethrough a full rotation of 360 degrees, or continue until you observe the cups beginning to expand.
• Confirm that thesuction cupsmaintain their parallel positioning. Should they exhibit signs of displacement, a minor adjustment by slightly releasing the suction cups is recommended, followed by repositioning the arms.

• Employing heat, utilize an iOpener and guide it between the Anti-Clamp’s arms. Alternative heat sources, such as a hair dryer, heat gun, or hot plate, are acceptable; however, exercise caution as excessive temperatures may compromise the display or internal battery.
• Position the iOpener in a folded configuration, resting it against the lower edge of the iPhone.
• Allow a sixty-second interval to permit the adhesive to soften and generate a separation.
• Once the Anti-Clamp establishes a substantial gap, carefully slide an opening pick beneath the screen’s surface.
• Should the Anti-Clamp fail to produce an adequate separation, increase the heat applied to the region and rotate the handle by ninety degrees.
• Avoid incremental rotations exceeding ninety degrees, and incorporate a sixty-second pause between each adjustment, allowing the Anti-Clamp and time to facilitate the separation process.
• Proceed past the subsequent three instructions.

The following three procedures detail the process of detaching the display assembly with the aid of a suction cup.
Applying heat to the iPhone's bottom edge will facilitate the loosening of the adhesive bonds holding the display in place, thereby simplifying the separation process.
Employ a hairdryer, or alternatively prepare aniOpenerand apply it to the iPhone's lower edge for approximately 90 seconds to reduce the adhesive's tackiness.

• Position a vacuum attachmentonto the bottom portion of the front panel, situated directly over the home button area.
• Ensure the vacuum attachment's surface remains clear of the home button's location to guarantee a secure bond between the attachment and the glass.

• Apply steady, consistent upward force to the suction cup to generate a small separation between the front panel and the rear casing.
• Introduce an opening tool, or a similarly slender prying implement, into the created space, inserting it approximately a few millimeters.
• The display is secured by a robust, waterproof adhesive; establishing this initial separation necessitates considerable force. Should you encounter difficulty in separating the components, 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.

• Utilize a prying tool to carefully work along the phone's corner and up its left side, progressing in the direction of the volume control buttons and the silent switch to sever the adhesive securing the display assembly.
• Pause your progress close to the upper left corner of the display surface.

A fragile wiring harness is situated along the right-hand side of your iPhone; avoid inserting any tools in this area to prevent potential harm to the cable.

• To release the adhesive, carefully reposition your tool at the lower-right edge of the iPhone, then maneuver it along the corner and up the right side, sliding to detach the adhesive.
• Ensure your opening tool does not penetrate beyond 3 mm, to prevent potential harm to the delicate display cable connections.

• Carefully elevate the display's lower border 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 interface with the display.

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

• Carefully insert a separation tool beneath the screen's upper boundary, working along the top edge to release the remaining adhesive sealant.

• To release the retaining clips securing the display assembly to the rear case, carefully move the display downwards, shifting it away from the phone's upper border.

To access the internal components, initiate the display opening process by pivoting the screen upwards 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 remain attached, linking it to the iPhone's main circuit board.
Secure the lifted display in an upright position using a support to prevent it from obstructing your work area during the repair.
