iPhone 7 Plus Taptic Engine Replacement

• To start the repair, ensure the iPhone's battery is depleted to a state where it registers as less than 20% capacity.One-quarter.Accidental puncture of a lithium-ion battery that is holding a charge presents a risk of fire and/or explosion.
• To prevent electrical shock or damage, ensure the iPhone is completely de-energized prior to starting the repair process.
• Using the appropriate screwdriver, detach the two screws.Use a screwdriver with a 3.4-millimeter pentalobe bit to loosen the screws.Employing a P2 screwdriver bit, secure the iPhone at its lower extremity.
• Removing the display assembly will damage the iPhone's water resistance; therefore, ensure you have new seals available to install, or prevent moisture contact during reassembly if you choose not to replace the seals.

• To avoid potential damage to your device, ensure the opening pick does not extend beyond a safe depth; therefore, mark the pick to indicate this limit.
• Determine the dimension using an appropriate measuring tool.Three millimeters.Using a permanent marker, clearly indicate the opening point on the pick.
• Alternative corner markings, using the same measurement tools, can be applied to the remaining corners of the pick.
• To assist with this procedure, affix a coin to the pick, positioning it 3 millimeters from the working end.

To simplify the opening process, the following three steps utilize the Anti-Clamp tool; if you do not have this tool, proceed to the instructions three steps further down.

Refer to the accompanying guide 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 iPhone’s left or right side.
• Affix one suction cup to the front surface of the iPhone, close to the lower edge and directly over the home button, and secure a second suction cup to the rear surface in the same relative position.
• Apply vacuum by pressing the cups firmly against the surface needing treatment.
• To improve the Anti-Clamp's adherence if the iPhone's exterior feels excessively smooth, apply adhesive tape to the device's surface.

• To secure the arms, advance the blue handle in the direction indicated.
• Rotate the handle in a direction that tightens it.Rotate fully.Continue the process, observing for signs of cup expansion.
• Maintain parallel positioning of the suction cups; should misalignment occur, gently release the suction cups' grip and reposition the arms.

• Apply heat toUtilize the iOpener device.Carefully guide the string through the arm openings.Prevent the clamp from engaging..
• To warm the display and/or battery, a hair dryer, heat gun, or hot plate may be employed; however, exercise caution as excessive heat poses a risk of damage to these components.
• Carefully bend theUse the iOpener.Position the component flush against the lower edge of the iPhone's casing.
• Allow a full 60 seconds for the adhesive to soften and create a separation.
• Using a specialized opening tool, carefully create a small space between the surfaces.
• Carefully disconnect the component, ensuring all connections are released, and then measure its resistance using a multimeter set to the appropriate range, aiming for a reading of 100 ohms ± 5 ohms.Prevent clamping.If the separation isn't adequate, increase the heat applied to that spot and adjust the handle by 90 degrees.
• Allow one minute of cooling time after each adjustment, limiting each rotation to a maximum of 90 degrees.Prevent clamping.Allow the specified duration for the process to complete automatically.

Employing a suction cup, proceed with the following three steps to detach the display assembly.

Applying heat to the phone's bottom perimeter with a heat gun or similar device will loosen the adhesive that holds the display in place, facilitating separation.

Apply heat with a hairdryer or utilize a heat gun, maintaining a temperature no higher than 150°F (65°C), to soften the adhesive securing the trim panel.Use the iOpener.To loosen the adhesive securing the lower portion, hold a heat source against that edge for approximately 90 seconds.

Using a suction cup, secure it to the front panel's lower section, positioned directly over the home button.

To ensure a proper seal between the suction cup and the front glass, avoid positioning the cup so that it covers the home button.

Apply steady, even force to lift the suction cup, generating a small separation between the screen assembly and the device's frame.

Using a specialized opening tool, carefully create a small space between the surfaces.

Due to the robust nature of the watertight adhesive securing the screen, separating it requires considerable force. Should you encounter difficulty, apply additional heat and incrementally move the screen back and forth to soften the adhesive, allowing for sufficient gap creation to accommodate tool insertion.

• Beginning at the bottom edge, insert the opening pick between the display and the phone's chassis along the left side, progressing upwards towards the volume buttons and silent switch to release the adhesive securing the display.
• Position yourself close to the upper left edge of the screen.
• Avoid separating the display's upper boundary from the back cover by force; delicate plastic fasteners secure them together and are susceptible to damage.

Avoid inserting your opening tool along the iPhone’s right side, as this area contains fragile wiring that could be harmed.

• Using your tool, begin at the lower-right edge of the iPhone and move it along the perimeter, releasing the adhesive by sliding it along the corner and up the right side.
• Limit pick insertion depth to avoid damage.Three millimeters.Carefully proceed to avoid harm to the display cables.

• Using a suction cup, apply upward force to the lower display perimeter to separate it.
• Ensure the display’s elevation remains below the specified maximum measurement.Set the temperature dial to 150 degrees.Careless handling can damage the display's ribbon cables, potentially causing them to stretch or rip.
• To detach the suction cup, grasp the small projection extending from its surface and apply traction.

• Use three screws, each measuring 1.2 millimeters.
• A screw with a 2.6-millimeter head diameter is required.

• Carefully disengage the battery connector from its socket on the logic board by applying upward pressure with a spudger tip.
• To avoid electrical connection and power delivery to the device, gently raise the connector cable a small amount.

• Carefully separate the two display connectors from their sockets on the logic board by applying upward pressure with the flat end of a spudger or a fingernail.
• Secure the connectors by applying even pressure to each end until you hear a distinct click; avoid applying pressure to the central portion. Any misalignment during this process risks bending the connector, potentially resulting in irreversible damage.

• Using a Y000 tri-point screwdriver, detach the bracket that covers the front panel sensor assembly connector by unscrewing its three fasteners.
• Begin the process by executing the action designated as "One."A screw with a diameter of 1.3 millimeters.
• Two.Use screws with a 1.0 mm diameter.

• Carefully detach the connector linking the front panel sensor assembly to its socket on the logic board.
• To reduce the chance of deformation, reconnect the press connector by attaching one end at a time.

• Carefully detach the display assembly, ensuring no damage occurs.
• If a display adhesive replacement is desired, stop the reassembly process at this point.

• Using a Phillips screwdriver, detach the barometric vent from the rear case by unscrewing the two screws that hold it in place.
• A single screw with a 2.9 mm head diameter is required.
• A screw with a 2.1 mm head diameter is required.

Using gentle pressure, slide the barometric vent toward the Taptic Engine to release the adhesive bond holding it in place along the iPhone's lower edge.

• Employ the tool's straight, planar edge.Use a plastic pry tool, often referred to as a spudger, to avoid scratching surfaces.Carefully separate the Taptic Engine connector from the corresponding socket on the logic board.

• Using the appropriate tool, detach the three.Use a Phillips screwdriver with a 1.5 mm tip.Affix the Taptic Engine to the rear case using the specified screws, ensuring proper alignment and torque as detailed in the service manual.
