iPhone 5 Screen Replacement

Begin by disconnecting the power source, ensuring the 120V AC supply is completely isolated, then use a 5/32-inch hex key to loosen the retaining screw securing the fan motor to the blower housing, carefully noting its position for reassembly, before gently extracting the motor assembly.
To mitigate the risk of additional shattering and potential injury while repairing a cracked display glass, secure it with tape.
Apply strips of transparent packing tape across the iPhone screen, ensuring complete coverage by layering them until the entire display surface is protected.
To safeguard your eyes from potential glass fragments that may detach during the repair process, it is essential to use safety glasses.

Using a 5/32-inch hex key, carefully loosen the four screws securing the fan assembly to the motor housing; ensure you do not overtighten when reassembling, as this could damage the plastic threads.
To prevent potential fire or explosion hazards during repair, ensure the iPhone's lithium-ion battery is depleted to less than 25% charge; a fully charged battery poses a significant risk of ignition if damaged.
To prevent electrical shock or damage, ensure the iPhone is completely de-energized prior to starting the repair process.
Using a Pentalobe screwdriver, detach the two screws measuring 3.6 mm located adjacent to the Lightning connector.

Using a 5/32-inch hex key, carefully tighten the three retaining screws on the motor mount to a torque of 3.5 Nm, ensuring the motor remains securely affixed and preventing excessive vibration; failure to achieve the specified torque could result in motor displacement and potential damage.
Carefully lift the display assembly—consisting of a glass screen, a plastic bezel, and integrated metal clips—from within the phone's chassis during the subsequent procedures.
Ensure complete removal of the display assembly, irrespective of the chosen tool.
When separation between the glass and plastic is observed, matching the visual example provided, use a plastic opening tool to insert it into the gap between the plastic frame and the phone’s metal chassis, carefully releasing the retaining clips.
To ensure proper closure during reassembly of a phone featuring a detached display bezel, apply a narrow adhesive strip positioned between the plastic bezel and the glass surface.

Using a 5/32-inch hex key, carefully tighten the three retaining screws on the motor assembly to a torque of 3.5 inch-pounds, ensuring not to overtighten and potentially strip the threads; observe caution to prevent damage to the motor.
To simplify the subsequent opening process, the following instructions utilize the Anti-Clamp tool, a custom design; if you do not have this tool, proceed two steps further to find an alternative procedure.
Refer to the included documentation for detailed procedures regarding Anti-Clamp operation.
To release the Anti-Clamp's arms, move the blue handle in a rearward direction.
Position the arms so they extend across the device's left or right side.
Affix two suction cups, one to the front and one to the rear surface of the iPhone, close to the lower edge, situated directly above the home button.
Apply vacuum by pressing the cups firmly against the surface you intend to work on.
To improve the Anti-Clamp's adherence if the iPhone's exterior feels excessively slick, apply adhesive tape to the device's surface.

Using a 5/32-inch hex key, carefully tighten the four mounting screws securing the fan assembly to the motor housing, ensuring each is snug but not over-tightened to prevent damage; observe a torque of 4-6 inch-pounds per screw.
To secure the arms, advance the blue handle in the direction indicated.
Rotate the handle fully, completing a 360-degree turn, observing for the initial signs of cup expansion.
Maintain parallel positioning of the suction cups; should misalignment occur, gently release the suction cups' grip and reposition the arms.
Once sufficient space is created by the Anti-Clamp, slide a prying tool beneath the display.
To ensure adequate separation, increase the heat applied to the component and then rotate the handle 90 degrees.
Allow one minute to elapse and avoid rotating the component more than 90 degrees incrementally, permitting the Anti-Clamp mechanism and time to facilitate the process.

Securely affix a suction cup to the display surface, positioning it directly over the home button area.
Ensure the screen's entire surface is covered by the cup to guarantee a secure, leak-proof connection.
To prevent shattered glass fragments from scattering and to provide a secure attachment point for the suction cup, apply several strips of packing tape to the cracked display surface, ensuring all air pockets are removed.

Secure the front panel assembly to the suction cup, ensuring a strong bond.
Using one hand to secure the iPhone, gently lift the suction cup to create a small gap between the front panel and the rear enclosure.
Exercise caution and use steady, even pressure when installing, as the display assembly has a more precise fit than typical device components.
Using a plastic opening tool, carefully separate the rear case from the display assembly by applying gentle prying pressure, simultaneously lifting with the suction cup.
To release the front panel assembly from the rear case, carefully disengage the multiple retaining clips, potentially requiring the coordinated use of both a suction cup and a plastic opening tool.

Carefully work a prying tool along the left and right edges of the front panel assembly to release the retaining clips.

Disconnecting the front panel assembly from the rear case is not recommended, because several ribbon cables remain connected at the top of the iPhone.
After disengaging the retaining clips located along the lower edge and sides of the front panel assembly, separate the assembly's bottom edge from the rear case by applying gentle outward pressure.
Carefully position the display at a 90-degree angle, then secure it in an upright position using a support to prevent it from moving during the repair process.
To avoid stressing the display's wiring during the repair process, secure it with a rubber band.

Using appropriate tools, detach the metal battery connector bracket from the logic board by unscrewing the two screws that hold it in place.
Use a Phillips screwdriver to remove a single screw with a 1.8 mm head.
Use a Phillips screwdriver to remove a single screw with a 1.6 mm head.

Detach the bracket securing the battery connector using a Tri-Point Y000 screwdriver.

Carefully lift the battery connector away from its connection on the logic board using a plastic opening tool, ensuring no force is applied.
Exercise caution to avoid accidentally moving the tiny components positioned near the socket.
Exercise extreme caution when releasing the battery connector, ensuring force is applied solely to the connector and not the logic board socket; applying pressure to the socket or the logic board could result in socket destruction or damage to adjacent components.

Detach the cable bracket that holds the front panel assembly wires by unscrewing the screws listed below.
Use two Phillips head screws, each measuring 1.2 millimeters.
Use a Phillips screwdriver to remove a single screw with a head size of 1.6 millimeters.
Due to its non-magnetic properties, this screw requires a regular screwdriver for removal; prevent loss during disassembly and ensure correct reinstallation, as a magnetized screw can disrupt compass functionality.

To detach the display cable bracket, raise it in the direction of the battery, then take it out of the iPhone.
To reassemble, secure the left-hand hooks to the logic board, then move the bracket outward toward the phone's exterior.

Prior to either detaching or reattaching the cables in this procedure, ensure the battery's power is completely isolated.
Carefully detach the three front panel assembly cables by gently separating them using a plastic opening tool or your fingernail.
The assembly includes the front camera unit and its associated cable.
Connect the display panel's flat, ribbon-like cable, ensuring proper alignment to the connector pins, and secure it with the retaining clip.
The flexible ribbon cable connecting the display's touch sensor to the mainboard is the digitizer cable.
Should the LCD cable become detached from its connector during reassembly, powering on the device may result in a blank screen or the appearance of white lines. To resolve this, re-establish the cable's connection and restart the phone; a complete restart is achieved by temporarily disconnecting and then reconnecting the battery.

Detach the front panel assembly from the rear case.
