• To ensure safety prior to commencing the repair, allow your iPhone's battery to deplete to a level below 25% capacity.A fully charged lithium-ion batteryposes a risk of ignition and/or detonation if it sustains accidental physical damage, such as a puncture.
• Deactivate your iPhone by powering it down completely before you start taking it apart.
• Using a suitable tool, extract the pair of 3.5 mm pentalobe screws located along the iPhone's lower edge.
• Separating the iPhone's display assembly will damage the integrated waterproof barriers; therefore, prepare replacement seals beforehand, or exercise extreme caution to prevent moisture ingress if you intend to reassemble the iPhone without new seals.

• To avoid potential harm to your device, ensure the opening pick isn't inserted beyond its intended depth; this procedure will help you identify a safe insertion point.
• Determine the distance of3 mmfrom the pick's leading edge, then use a permanent marker to create a visible indicator on the opening pick.
• For additional reference, consider marking the other corners of the pick with varying measurements.
• As another option, affix a coin to the pick's shaft,3 mmaway from its tip.

• To minimize additional damage and potential injury while repairing a fractured iPhone display, secure the broken 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 adhere properly during subsequent steps, create a handle by folding a durable tape, like duct tape, and use this to carefully elevate the screen.
• As a last resort, you may secure the suction cup to the screen using superglue.

• The following three procedures 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 past these three steps to 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 hold on the intended area.
• Should the iPhone's surface prove too slick for the Anti-Clamp to maintain adhesion, applying tape can create a more textured surface for improved grip.

• To engage the locking mechanism, draw theblue handlein a forward direction.
• Rotate thehandlethrough a complete rotation of 360 degrees, or until you observe the cups beginning to expand.
• Confirm that thesuction cupsmaintain their parallel positioning. Should the suction cups exhibit any signs of displacement, gently reduce their suction and reposition the arms.

• Employing heat, utilize an iOpener and carefully 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, ensuring it rests along the iPhone’s lower edge.
• Allow a sixty-second interval to permit the adhesive to soften and create a separation.
• Once the Anti-Clamp establishes a noticeable gap, slide an opening pick beneath the display screen.
• Should the Anti-Clamp fail to generate an adequate separation, increase the heat applied to the region and rotate the handle by ninety degrees.
• Avoid incremental rotations exceeding ninety degrees, and observe a sixty-second pause between each adjustment; permit the Anti-Clamp and time to facilitate the separation process.
• Omit the subsequent three procedures.

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 lower edge of the iPhone 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's location.
• Ensure the vacuum attachment's surface area remains clear of the home button to guarantee a complete bond between the attachment and the glass surface.

• Apply steady, consistent upward force to the suction cup to generate a minimal separation between the front panel assembly and the device's rear casing.
• Introduce an opening tool, or a similarly slender prying implement, into the created space, penetrating approximately a few millimeters.
• The display is secured by a robust, waterproof adhesive; establishing this initial separation requires 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 until a sufficient gap is achieved for tool insertion.

• Utilizing a specialized tool, carefully maneuver it along the perimeter's curve and ascend the phone's left side, progressing in the direction of the volume adjustment buttons and the mute switch, to disrupt the adhesive securing the display assembly.
• Pause your actions close to the upper-leftmost point 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 thecable.

• Carefully reposition your repair tool at the lower-right edge of the iPhone, then maneuver it along the corner and upward along the right side to release the adhesive bond.
• Ensure your opening tool does not penetrate deeper than3 millimeters, 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 link 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 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 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 opening process by pivoting the display upwards, originating from the left edge, mimicking the action of opening a book's cover.
Refrain from completely disconnecting the display at this stage, because multiple delicate ribbon cables remain attached, linking it 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.

• Detach the four screws that hold the lower display cable bracket in place on the logic board.These screws utilize a Phillips (JIS) head.The screws vary in length, as detailed below:
