• To ensure safety prior to commencing the repair process, allow the iPhone's battery to deplete to a level below 25% capacity.A fully charged lithium-ion battery presents a fire hazard and potential explosion risk if it sustains accidental physical damage.Deactivate the iPhone's power supply by turning it off completely before any disassembly work is undertaken.
• The two screws, each measuring 3.5 mm in diameter and utilizing a pentalobe head, are located on the iPhone's lower edge and must be removed.
• Separating the iPhone's display assembly will irreversibly damage the integrated waterproof barriers.
• Procure replacement waterproof seals beforehand and prepare for their installation, or exercise extreme caution to prevent liquid ingress if the iPhone is reassembled without new seals.

• Excessive insertion of a prying tool poses a risk of device damage; implement the following procedure to identify a safe insertion depth.
• Accurately gauge a distance of3 mmfrom the tool's distal end and use a permanent marker to create a visible indicator on the prying tool.
• For enhanced precision, consider marking additional corners of the tool with varying measurement distances.
• As an alternative method, affix a coin to the prying tool's tip using adhesive tape, positioning it3 mmfrom the distal end.

The following three procedures illustrate the utilization of the Anti-Clamp tool, which was specifically engineered to simplify the initial separation process; if this tool is not available, proceed to the subsequent three steps for an alternative approach.

Detailed guidance regarding the Anti-Clamp's operation can be found in a separate, dedicated instructional document.

• To release the locking mechanism, retract the blue handle, thereby disengaging the Anti-Clamp's gripping arms.
• Carefully position the arms across either the left or right side of the iPhone's frame.
• Secure the suction cups close to the lower edge of the iPhone, situated directly above the home button, with one cup placed on the front surface and the other on the rear.
• Apply pressure by compressing the cups together, creating a secure vacuum seal on the intended areas of the device.
• Should the iPhone's surface exhibit excessive slipperiness, hindering the Anti-Clamp's ability to maintain adhesion, applying adhesive tape can improve the grip.

• Advance the blue handle to secure the arm assemblies in their locked position.
• Rotate the handle in a clockwise direction.Continue the rotation until a full revolution, or until visible deformation of the suction cups is observed.Maintain consistent alignment between all suction cups throughout the process.
• Should the suction cups become misaligned, slightly release their hold and reposition the arm components for proper alignment.

• Employing a heated iOpener, carefully maneuver it between the Anti-Clamp’s arms is the initial step.Alternative heat sources, such as hair dryers, heat guns, or hot plates, are permissible; however, excessive temperatures risk damaging the display assembly or internal battery, necessitating caution.Position the iOpener to rest along the lower edge of the iPhone’s casing.Allow a full minute for the adhesive bond to weaken and create a discernible separation.Introduce an opening pick into the newly formed gap.
• Should the Anti-Clamp fail to establish an adequate separation, increase localized heat and incrementally rotate the handle by 90 degrees.
• Avoid exceeding a 90-degree rotation increment, and observe a one-minute interval between adjustments.Rely on the Anti-Clamp's leverage and the passage of time to facilitate separation.The iOpener’s purpose is to assist in separating the device’s components.
• Careful application of heat is essential for successful disassembly.
• The adhesive securing the display requires time to soften.
• A small gap is needed to insert the opening pick.Incremental rotation of the Anti-Clamp handle allows for controlled separation.Patience is key to preventing damage during the separation process.
• The Anti-Clamp provides mechanical advantage to overcome adhesive bond.Monitor the display and battery for any signs of heat damage.Allow sufficient time for the adhesive to release before proceeding.

Instructions for detaching the display assembly involve utilizing a suction cup, as detailed in the following three procedures.

• To facilitate separation, applying heat to the phone's bottom border will reduce the bond strength of the adhesive securing the display.
• Employing a hairdryer or an iOpener is recommended for generating the necessary heat.The iOpener, or hairdryer, should be applied to the lower edge of the iPhone's casing for approximately 90 seconds.This heating process serves to soften the adhesive layer located beneath the display.

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

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

• Apply steady, consistent upward force to the suction cup to generate a minimal separation between the display assembly and the device's surrounding structure.
• Introduce an opening tool into the newly formed space.
• Due to the robust nature of the waterproof sealant securing the display, a considerable amount of force may be necessary to initially disengage the screen; if encountering difficulty, apply additional heat and gently oscillate the screen to reduce adhesive strength until a sufficient gap is achieved for tool insertion.

• Begin separating the display assembly from the chassis by inserting a prying tool into the lower edge of the phone's left side, then carefully maneuvering it upwards towards the volume buttons and the silent switch, which will disrupt the adhesive seal.
• Cease the separation process when the tool reaches the upper-left portion of the display's surface.
• Avoid attempting to dislodge the display's upper edge from the rear housing, because it is secured with fragile plastic clips that are susceptible to damage.

Fragile wiring is situated along the iPhone's right side; avoid inserting any tools in this area to prevent potential cable damage.

• To release the adhesive securing the iPhone, reposition your opening tool at the lower-right edge and maneuver it along the corner and up the right side.
• Ensure the tool's insertion depth remains below 3 mmto prevent potential damage to the delicate display cable connections.

• Employing a delicate upward force on the suction cup facilitates separation of the display's lower border.
• The display's elevation should be restricted to a maximum angular displacement of 15 degrees to prevent potential damage to the flexible ribbon cable connectors.Exceeding this angle carries a risk of stressing or rupturing these sensitive cable assemblies.To detach the suction cup, grasp and exert traction on the small protrusion located on its surface.
• This action will disengage the suction cup from the front panel assembly.

• Initiate the iPhone's disassembly process by pivoting the display assembly upwards, originating from the left edge, employing a motion similar to opening a book's cover.
• Refrain from completely disconnecting the display at this stage, because multiple delicate ribbon cables maintain its electrical connection to the device's logic board.
• To maintain accessibility during the repair, secure the display in an upright position by resting it against a stable support.

• Incorrect screw placement can result in irreversible damage to the device's components.
• After loosening the screws, proceed with removing the bracket itself.

• Employ the tip of a spudger to disengage the battery connector from its corresponding receptacle on the logic board.The battery connector’s cable should be gently flexed away from the logic board’s socket to ensure electrical isolation during the repair process.This precaution prevents unintended power delivery to the device’s internal circuitry.
• Avoiding contact between the connector and socket is crucial to maintain a safe working environment.

• Employ the tip of a spudger to disengage the lower display connector from its receptacle.For reattachment, apply pressure to one edge of the connector until a secure click is heard, then mirror the process on the opposing edge.Avoid applying pressure to the central portion of the connector during reattachment to prevent deformation.
• Even minor misalignment during reattachment can induce bending of the connector, potentially resulting in irreversible damage.

• Employ the tip of a spudger to release the connector securing the second lower display cable.Carefully separate the second lower display cable from its connection using a spudger's pointed end.A spudger should be utilized to detach the second lower display cable's connection.
