Step 1: Heating the Device

To begin the repair, place your phone face down on a heat mat set to 85°C for about five minutes. The heat softens the adhesive holding the back cover. If you don’t have a heat mat, a hairdryer or heat gun will work just as well. Once the phone is hot to the touch, apply some isopropyl alcohol around the edges to further soften the adhesive and make it easier to remove the back cover.

Step 2: Removing the Back Cover

Use a single-sided razor blade to create a small gap between the back cover and the chassis, starting from the bottom. Insert a plastic guitar pick into the gap and gently run it along the edge to separate the cover. If you encounter resistance, apply more isopropyl alcohol and continue. Once three of the four edges are free, lift and carefully pry the cover away from the chassis.

Step 3: Removing Internal Components

With the back cover off, use a cross-head screwdriver to remove the nine screws holding down the plastic shield that protects the logic board. If the screws don’t stick to your screwdriver, use tweezers to pick them out. Next, move to the bottom of the phone and remove the seven screws securing the loudspeaker and subboard cover.

Step 4: Disconnecting the Battery and Other Cables

Lift the loudspeaker and subboard cover with tweezers. At the top of the phone, pry up the plastic cover protecting the motherboard, being careful with the NFC antenna. Disconnect the battery and pop out the SIM tray. Use a plastic spudger to disconnect the screen and tweezers to detach the fingerprint sensor and blue coaxial cable from the chassis.

Step 5: Removing the Motherboard and Subboard

Carefully detach the motherboard using tweezers, keeping everything attached. Remove the subboard in a similar manner. Apply isopropyl alcohol around the battery to soften its adhesive and let it soak for five minutes.

Step 6: Transferring Components to the New Chassis

While waiting for the alcohol to soak in, check the new screen to ensure all necessary components are included. If not, transfer any missing parts, like small brackets or the antenna board, from the old chassis to the new one. Secure any loose parts with screws or adhesive.

Step 7: Removing and Reinstalling the Battery

Use a suction cup to wiggle the battery free from the chassis. Smooth out any ripples in the back of the battery with a plastic pick. Place the battery into the new chassis, ensuring it sits flush and secure.

Step 8: Reinstalling the Motherboard and Subboard

Carefully reinsert the motherboard and subboard into the new chassis, ensuring they fit snugly. Reattach the fingerprint sensor and reconnect the screen flex cable. Thread the blue coaxial cable back into place, ensuring it clicks securely.

Step 9: Reconnecting the Battery and Other Components

Reconnect the battery and reattach the wireless charging coil or NFC antenna. Replace the plastic cover over the motherboard and secure it with the nine screws removed earlier. Reinsert the SIM tray and move to the bottom of the phone to secure the subboard with seven screws.

Step 10: Final Checks and Sealing the Phone

Before sealing the phone, double-check all connections and screws. Replace the adhesive around the edges with Tesa tape for a secure seal. Peel back the backing sheet on the tape and press the back cover firmly in place. Finally, remove the plastic film from the front screen, turn on the device, and test it to ensure everything works correctly.
