3. Target temperature: ~70-80°C (160-175°F)

Step 3: Separate the Back Glass

1. Place suction cup near the bottom edge
2. Apply gentle pressure while inserting a plastic pry tool
3. Work slowly around the edges to separate the adhesive
4. Avoid forcing - if resistance is high, apply more heat

Step 4: Access Internal Components

1. Remove 10 Phillips screws securing the mid-frame
2. Lift the mid-frame carefully with a plastic tool
3. Disconnect the battery FIRST (critical safety step!)
4. Remove the wireless charging coil (4 more screws)

Step 5: Remove the Damaged Screen

1. Disconnect display cables (2 connectors)
2. Apply heat to the front edges to loosen screen adhesive
3. Use suction cup and plastic cards to separate the screen
4. Work methodically from bottom to top

Step 6: Install New Screen

2. Apply new adhesive around the edges
3. Connect the new screen and do a test boot before sealing
4. Press firmly for 30-60 seconds to ensure proper adhesion

Step 7: Reassemble Your Phone

1. Reinstall wireless charging coil and mid-frame
2. Replace all screws (don't overtighten)
