Step 2: Power Off and Remove Pentalobe Screws

• Power off your iPhone before beginning any disassembly to prevent electrical damage.
• Locate the two 6.8 mm-long pentalobe P2 screws at the bottom edge of the iPhone.
• Use a pentalobe screwdriver to remove the two screws.
• Keep the screws safe; they are small and easy to lose.

Step 3: Mark the Opening Pick

An opening pick can damage your device if it is inserted too far. To label your pick and guard against harm, follow this step.

• Mark the opening pick with a permanent marker by measuring three millimeters from the tip.
• Additionally, you have the option to mark the pick's other corners with various measurements.

Step 4: Cover any Fractures with Tape

• If the rear glass of your iPhone is cracked, cover the glass with tape to stop more damage from occurring and to protect yourself while fixing it.
• Using clear packaging tape, cover the entire face of the iPhone by placing overlapping pieces over the glass.
• To shield your eyes from any glass that may be shaken loose during the repair, put on safety glasses.
• If the suction cup does not stick after a few attempts, use a strong piece of tape (duct tape, for example) folded into a handle to lift the back glass.
• You can superglue the suction cup to the rear glass if everything else fails.

Step 5: Warm the All Side Edges

• Use a hair dryer or a heat gun to heat the bottom edge of the iPhone for about 90 seconds.
• Ensure the screen is slightly too hot to touch, but avoid leaving the hair dryer in one spot for too long.
• Apply a suction handle to the bottom edge of the rear glass, avoiding the very edge.
• Pull up on the suction cup with firm, constant pressure to create a gap between the rear glass and the frame.
• Insert an opening pick into the gap created by the suction handle.
• The adhesive is very strong; if necessary, apply more heat and gently rock the rear glass to weaken the adhesive.
• Use the hair dryer to heat the left edge of the iPhone for another 90 seconds or until hot to touch.
• Slide the opening pick around the lower left corner and up the left edge to slice through the adhesive.
• Avoid inserting the pick more than 3 mm to prevent damaging internal components.
• Repeat the heating process on the right edge (with the power button) for 90 seconds.
• Re-insert the pick at the bottom edge and slide it up the right side, separating the adhesive.
• Heat the top edge of the iPhone for 90 seconds and insert the pick underneath the top right edge.
• Slide the pick around the top-right corner and halfway across the top edge to complete the separation of the rear glass.

Step 6: Separate the Left Adhesive

• The cables along the left edge are delicate and easy to damage with a pick.
• Insert a second opening pick into the bottom left corner of the iPhone.
• Carefully twist both picks simultaneously until the left edge clips release.
• Apply the twisting force gradually to avoid damaging the internal components.
• If you encounter resistance, reheat the left edge with a hair dryer or heat gun for about 90 seconds.
• Once the adhesive is sufficiently heated, repeat the twisting motion to continue separating the left edge.
• Ensure the picks are not inserted more than 3 mm to prevent damage to the cables.
• Keep a firm grip on the device to maintain control during the process.
• Patience is key; work slowly to avoid unnecessary damage.
• Once the left edge adhesive is separated, you can move on to the other sides of the iPhone.

Step 7: Shut Down and Open Your iPhone

• To protect your iPhone from any electrical damage, turn it off entirely.
• Take out the two pentalobe screws located at the phone's bottom.
• Lift the front panel carefully, using the suction handle.
• To create a space, place the plastic spudger between the frame and the display.
• To free the clamps keeping the display in place, move the spudger down the edges.
• Carefully open the iPhone from the right side, much like you would a book.
• To prevent harming the cords, make sure you don't pull the display too far.

Step 8: Remove the Battery Connector Cover 

• Use a Y000 screwdriver to remove the eight screws securing the battery connector cover.
• Remove the five 1.3 mm-long screws first.
• Next, remove the two 1.6 mm-long screws.
• Finally, remove the one 1.9 mm-long screw.
• Keep track of each screw to ensure it goes back in its original place to avoid damaging your iPhone.
• During reassembly, power on your iPhone to test all functions before sealing the screen back in place.

Step 9: Disconnect the Battery

• Use the pointed end of a spudger to disconnect the battery cable by prying the connector straight up from its socket.
• Avoid damaging the black silicone seal surrounding this and other board connections, as these seals provide extra protection against water and dust intrusion.
• Bend the connector slightly away from the logic board to prevent it from accidentally making contact with the socket.
• Ensuring the connector doesn't touch the socket prevents the phone from powering on during the repair.
• Handle the spudger with care to avoid slipping and causing damage to nearby components.
• Double-check that the battery is fully disconnected before proceeding to the next step.

Step 10: Disconnect the Charging Coil

• Use a plastic spudger or your fingernail to gently pry up the charging coil connector from its socket.
• Lift the connector straight up to avoid bending or damaging the pins.
• Ensure you handle the charging coil connector carefully to prevent tearing or breaking the delicate wires.
• Keep the charging coil connector away from the socket to prevent accidental reconnection during the repair.

Step 11: Take Out the Back Glass Assembly.

• Take out the back glass assembly.
• When fresh glue is required, apply it after thoroughly cleaning the affected regions with isopropyl alcohol (>90%).
• This is where you stop during reassembly if you want to change the rear glass adhesives.

Step 12: Take Out the Taptic Engine Fasteners

• Take off the four screws holding the Taptic Engine in place with a Phillips screwdriver.
• The Taptic Engine connecting bracket can be taken off with a pair of tweezers.
• To disconnect the Taptic Engine, pull the connector straight up out of its socket using the pointed end of a spudger.
• The 3.1 mm-long standoff screw can be taken out with a standoff driver.
• The ideal tool to use to remove standoff screws is a standoff driver or driver bit.
•  A little flathead screwdriver can work in a pinch, but be extra careful to make sure it doesn't slip and harm nearby components.
• To extract the Taptic Engine, use your fingers or a pair of tweezers.

Step 13: Take Out the Metal Bracket

• The metal bracket is fastened to the frame with a few clips on the bottom.
• To remove the metal bracket's clips from the frame, carefully pull it upright with a pair of tweezers.
• Be sure to properly line the bracket and reposition the metal clips into the frame's recess when assembling the parts.
• Take out the metal bracket.

Step 14: Get to the Loudspeaker

• Find the phone's loudspeaker, which is located near the bottom.
• Determine which screws hold the speakers in place and remove them.
• Cut any cables that are connected to the loudspeaker.
• To remove the loudspeaker gently, use a spudger or tweezers.
• Clear out the loudspeaker chamber of any dust or debris.

Step 15: Put in the New Speaker

• The new loudspeaker should be positioned exactly where the previous one was.
• Reattach any wires that are connected to the loudspeaker.
