iPhone 6s Taptic Engine Replacement - iPhone 6s

Step 1 | Pentalobe Screws

To prevent potential hazards and damage, ensure the iPhone’s battery is depleted to a state where its voltage is below.One-quarter.Accidental puncture of a lithium-ion battery that is holding a charge presents a fire and/or explosion hazard.
Prior to starting the iPhone's disassembly process, ensure the device is completely de-energized.
Using the appropriate screwdriver, detach the two 3.5mm screws.Use a screwdriver with a 3.4 mm P2 Pentalobe bit to loosen the screws.Locate the two speaker openings situated along the iPhone's lower edge, flanking the Lightning connector.

Step 2 | Anti-Clamp instructions

For those utilizing the Anti-Clamp tool, the following two procedures simplify the opening process; otherwise, proceed directly to the instructions three steps below for an alternative approach.
Refer to the included guide for detailed procedures regarding the Anti-Clamp's operation.
To release the Anti-Clamp's arms, move the blue handle in a rearward direction.
Position the arms so they extend across the iPhone's left or right side.
Affix a suction cup to the front of the iPhone, close to the lower edge and directly over the home button, and another suction cup to the rear surface in the same relative position.
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.

Step 3

To secure the arms, advance the blue handle in the direction indicated.
Rotate the handle in a direction that tightens it.Rotate fully around its axis.Monitor the process and cease operation when the cup material begins to visibly expand.
Maintain parallel positioning of the suction cups; should they become misaligned, gently release the suction cups' hold and reposition the arms.
Once sufficient separation is achieved by the Anti-Clamp tool, slide a separating tool beneath the display panel.
To ensure adequate separation, reposition the handle by 90 degrees.
Allow the Anti-Clamp device to function and permit several seconds of inactivity following each incremental adjustment, limiting each rotation to a maximum of 90 degrees.

Step 4 | Opening Procedure

Lacking an Anti-Clamp tool, proceed with the following three steps to utilize a suction handle.
Using a heat gun or hairdryer set to a low setting, warm the bottom of the iPhone's display assembly to soften the adhesive securing it.Use a specialized iOpener tool.Apply heat using a hair dryer, maintaining the device's proximity to the component for roughly 60 seconds.
Applying heat will loosen the adhesive bonds holding the display in place, facilitating separation.

Step 5

To access the 6s display, carefully release the adhesive strip encircling its edges; replacement adhesive strips should be prepared beforehand if desired. Completing the repair without fresh adhesive is feasible and unlikely to affect device operation.
Using a suction cup, secure the lower left corner of the display assembly.
Avoid positioning the suction cup directly on the home button.
To facilitate suction cup attachment on a severely cracked display, apply a sheet of clear packing tape across the damage; as an alternative, a robust adhesive tape can be substituted for the suction cup. Should these methods prove ineffective, secure the suction cup directly to the fractured screen using superglue.

Step 6

Using a 5/32-inch hex key, carefully tighten the three mounting screws securing the fan assembly to the motor housing, ensuring each is snug but not overtightened to avoid damaging the plastic.

Apply steady, even force to lift the suction cup, generating a small separation between the front panel and the rear case.
Exercise caution and use steady, even pressure during installation; the display unit's fit is significantly snugger than typical device components and secured with adhesive.
To avoid display assembly damage, use minimal force when separating it from the rear case; the goal is to establish a slight separation.
To ease separation of the display from the frame, apply warmth to the front surface of the iPhone with an iOpener, hair dryer, or heat gun until the exterior reaches a temperature just beyond comfortable touch, which will loosen the adhesive bonds along the perimeter.

Step 7

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 that you do not overtighten and damage the threads.
Start the separation process by gently inserting a plastic opening tool into the small gap located on the phone's bottom edge, directly over the headphone jack.

Using a spudger, insert its flat edge into the separation between the display assembly and the back cover, positioning the insertion point immediately over the headphone jack.

Step 8

Carefully align the 4mm hex key to the setscrew, ensuring it engages fully, then tighten the setscrew to a torque of 1.5 Nm using the torque wrench.
Using a spudger, gently increase the separation between the front panel assembly and the phone's main body.

Step 9

Using a 5/32-inch hex key, carefully tighten the four M4x8mm screws securing the fan assembly to the heatsink, ensuring a torque of 4.5 in-lbs to prevent damage.

Using the tool's straight edge, carefully guide it into the designated space.Use a plastic spudger.Locate this component on the device’s left lateral edge, situated in the space separating the display assembly and the rear case.
Carefully move theUse a plastic pry tool, often referred to as a spudger, to avoid scratching surfaces.Carefully lift the device's side to release the adhesive bond and disengage the retaining clips.

Step 10

Using a 5/32-inch hex key, carefully tighten the four M4x8mm screws securing the fan assembly to the heat sink, ensuring a torque of 4.5 in-lbs to prevent damage.

Carefully detach theUse a plastic pry tool, often referred to as a spudger.Carefully align the component with its original position at the lower edge of the device, the area previously accessed by separating the housing.
Carefully move theUse a plastic pry tool, often referred to as a spudger, to avoid scratching surfaces.Locate the edge of the device on its right side, following the lower boundary.

Step 11

Carefully move theUse a plastic pry tool to gently separate.Proceed along the right edge, carefully releasing the adhesive bond and disengaging the display clips from the iPhone's chassis.

Step 12

Employ the specified tool to carefully manipulate the component, ensuring a torque of 5.2 Newton-meters is applied, and observe the safety precautions regarding potential pinch points and the risk of damaging the retaining clip.Employ a vacuum-creating device to secure the component.Carefully separate the display assembly from the device housing by releasing the remaining adhesive bond.
To prevent damage to the three cables securing the display at the top, limit its opening angle to a maximum of 90 degrees; exceeding this could cause them to tear.

Step 13

To detach the suction cup, grasp the small protrusion located on its upper surface and lift upwards, separating it from the front panel.

Step 14

Carefully raise the display assembly by leveraging the retaining clips located at the top edge of the front panel, which will act as a pivot to separate the phone's housing.
Carefully position the display at a roughly 90-degree angle, then secure it in an upright position using a support to prevent it from falling during the repair process.
To avoid stressing the display's wiring during the repair process, secure it with a rubber band.
As a temporary substitute, an unused, sealed can of soda can be employed to secure the display in place.
If a display adhesive replacement is desired, halt the reassembly process at this point.
To ensure proper closure and secure clipping of the cover during reassembly, guide the camera-side edge of the screen body beneath the main body's edge, positioning the screen frame's hooks beneath the main body's rim and then gently pressing toward the camera end to achieve a tight fit.
Ensure these clasps are positioned beneath the phone's outer edge, as they function as retention points rather than a traditional hinge, facilitating a smooth and controlled screen closure with a gentle snap.
To reinstall the screen, begin by applying pressure to secure the upper right corner, working downwards along the edge, followed by the upper left corner.

Step 15 | Battery Connector

Using a Phillips screwdriver, detach the battery connector bracket by unscrewing the two fasteners, each measuring the same length.
Utilize a 2.9 mm screw for installation.
