• As a preliminary precaution, ensure your iPhone's battery is depleted to a level below 25% prior to commencing the repair process.A fully charged lithium-ion batteryposes a fire hazard and/or risk of explosion if it sustains accidental punctures.
• Deactivate your iPhone by powering it down completely before you start disassembling it.
• Utilize a screwdriver to extract the pair of 3.4 mm pentalobe screws located along the iPhone's lower edge.
• Separating the iPhone's display assembly will damage the integrated waterproof seals; therefore, prepare replacement seals beforehand to prevent liquid ingress, or exercise extreme caution to prevent moisture exposure 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 details how to mark the pick to safeguard against such damage.
• Determine the distance of3 mmfrom the pick's leading edge and use a permanent marker to create a visible indication on the opening pick.
• For enhanced reference, consider marking the other corners of the pick with varying measurements.
• As an alternative method, affix a coin to the pick's shaft,3 mmaway from its tip.

The following three procedures illustrate the function of the Anti-Clamp, a specialized tool developed to simplify the initial opening process; if this tool is not available, proceed to the subsequent three steps for an alternative approach.

Detailed instructions regarding the Anti-Clamp's operation can be found in a separate, dedicated guide.

• To release the Anti-Clamp's gripping arms, retract the blue handle towards the rear.
• Carefully position the arms across either the left or right side of the 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 face and one on the rear.
• Apply pressure by compressing the cups together to establish a secure suction hold on the intended surface.
• Should the iPhone's surface prove excessively smooth, preventing adequate adhesion by the Anti-Clamp, applying adhesive tape can provide a more textured interface for improved grip.

• To secure the arms, advance the blue handle in a forward direction.
• Rotate the handle in a clockwise direction,a full 360 degrees,or continue until you observe the suction cups beginning to deform.
• Maintain the proper alignment of the suction cups with one another; should they become misaligned, slightly release the suction cups and reposition the arms.

• Employ a heating device, such as an iOpener to carefully guide it between the arms of the Anti-Clamp.
• Alternative heat sources, including hair dryers, heat guns, or hot plates, are acceptable; however, excessive temperatures may compromise the display or internal battery, necessitating cautious operation.
• Position the iOpener to rest along the lower edge of the iPhone’s casing.
• Allow a sixty-second interval to permit the adhesive to soften and create a separation.
• Introduce an opening tool into the newly formed space.
• Should the Anti-Clamp fail to establish an adequate separation, increase the heat application to the area and rotate the handle by ninety degrees.
• Avoid exceeding a ninety-degree rotation at any point, and observe a sixty-second pause between adjustments; allow the Anti-Clamp and time to facilitate the separation process.

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

• Applying heat to the bottom edge of the iPhone facilitates the loosening of the adhesive bonds holding the display in place, which simplifies the separation process.
• Employ a hairdryer, or alternatively, prepare aniOpenerand apply it to the lower edge of the device for approximately 90 seconds to reduce the adhesive's tackiness.

Securely affix a suction cup to the bottom portion of the front panel, positioning it directly over the home button area.

Ensure the suction cup's surface remains clear of the home button's location to guarantee a complete and airtight bond between the cup and the glass.

• Apply steady, forceful upward pressure to the suction cup to generate a small separation between the display assembly and the device's surrounding structure.
• Carefully slide an opening tool into the newly formed space.
• Due to the robust, waterproof sealant securing the display, establishing this initial separation requires considerable effort; should you encounter difficulty, applying additional heat and gently oscillating the display upwards and downwards will help to soften the adhesive, facilitating the creation of a sufficient gap for tool insertion.

• Begin separating the phone's display assembly by inserting a separation tool beneath the left edge, initiating the process at the bottom and progressing upward toward the volume controls and the silent switch, effectively disrupting the adhesive seal securing the display.
• Cease the separation process in close proximity to the upper-left corner of the display.
• Refrain from attempting to disengage the display's top edge from the rear casing, because it is secured by fragile plastic clips that are susceptible to breakage.

Along the right side of your iPhone, you'll find sensitive wiring; avoid inserting any tools 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 up the right side, sliding it 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 raising the display beyond an angle of15 degreeslest you jeopardize the integrity of the flexible ribbon cables that link the display.
• Detach the suction cup from the front panel by grasping and pulling on the small protrusion located on its surface.

• Initiate the iPhone's disassembly 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 display in an upright position using a support to prevent it from falling during the repair procedure.

• To detach the lower connector bracket, first extract the four Y000 tri-point screws that hold it in place, noting their individual lengths.
• Specifically, three screws measure 1.2 millimeters in length.
• A single screw is 2.4 millimeters long.
• During this repair process, meticulously organize and document the location of each screw, ensuring their correct reinstallation to prevent potential damage to your iPhone.

• Employ the tip of a spudger to disengage the battery connector from its corresponding receptacle on the logic board.spudgerGently elevate the connector cable a small amount to ensure it remains disconnected from the socket, thus preventing any power delivery to the device.
• Bend the connector cable up slightly to prevent it from making contact with the socket and providing power to the phone.

• Prior to detaching or reattaching any cables in this procedure, ensure the battery is completely disconnected to prevent potential electrical hazards.
• Employ a spudgeror a fingernail to release the two lower display connectors; accomplish this by applying upward pressure directly above them to separate them from their corresponding sockets on the logic board.
• When reattaching these connectors, apply pressure to one end until you hear a distinct clicking sound, then repeat the process for the other end; avoid applying pressure to the central portion of the connector, as this can lead to bending and irreversible damage.
• Should you observe a blank screen, the appearance of white lines on the display, or a partial or complete absence of touch functionality following reassembly, attempt to carefully disconnect and reconnect both cables, verifying their complete and secure placement.

• Detach the pair of 1.3 mm Phillips #000 screwswhich fasten the bracket that covers the connector for the front panel sensor assembly.
• Certain devices may exhibit Y000. Apple introduced the Y000 screw type during the product's operational history.

• To prevent damage, detach the connector linking the front panel sensor assembly to the socket located on the logic board.
• To reduce the possibility of deformation, ensure this press-fit connector is reattached by engaging one end at a time.

• Detach the display assembly from the device.
• If you intend to substitute the adhesive securing the display's perimeter during reassembly, halt the process at this juncture.

• To detach the earpiece bracket from the front panel, first eliminate the three Phillips head screws that hold it in place.
  The bracket is fastened with two screws, each measuring 2.6 millimeters in length.
  A single 1.7-millimeter screw is also utilized in the assembly.

• Detach the securing bracket that holds the earpiece speaker in place.

• A single screw with a diameter of 1.9 millimeters is required.1.9 mm screw
• Additionally, a screw measuring 2.5 millimeters in diameter is also needed.2.5 mm screw

• Allow approximately two minutes to elapse before proceeding to the subsequent repair stage, ensuring the adhesive is sufficiently pliable.

• Employ a spudgerto carefully disengage the ambient light sensor from its housing on the device's front surface.
• Ensure the tool's insertion extends completely beneath the sensor to detach it from the underlying transparent plastic component. Applying force solely to the cable risks severing the sensor from its wiring harness, necessitating a replacement. However, this concern is irrelevant should a sensor/cable assembly replacement already be planned.

• Advance the specified tooltoolin a direction leading to the front-facing camera assembly, releasing the adhesive that secures the cable to the front panel.
• Cease movement immediately prior to reaching the screw mounting locations.

• Employ thetoolto elevate the camera cable from its secured position atop the pair of plastic supports situated on the front panel, thereby releasing it from the remaining adhesive.
