Tools & Parts Needed (DIY)
Always use the correct tools for your specific model. Using wrong-sized screwdrivers can strip screws and cause additional damage.
Step-by-Step DIY Guide
Follow these steps carefully. Take photos at each stage for reference during reassembly.
Power off and prepare
Turn off your Apple iPhone 12 completely. Discharge the battery below 25% to reduce fire risk if the battery is accidentally punctured during disassembly.
Heat and separate the screen
Apply heat around the screen edges for 2–3 minutes to soften the adhesive. Attach a suction cup near the bottom edge and pull while sliding a plastic opening pick into the gap. Work slowly around the perimeter.
Do not insert the pick more than 2 mm deep — flex cables run directly beneath the screen edges and are easily severed.
Disconnect the battery
Remove the shield plate covering the battery connector and disconnect it from the logic board using a plastic spudger. Always disconnect the battery before touching any other cable to prevent short circuits.
Detach the display cables
Remove the bracket screws securing the display flex cables. Gently pry each connector upward with a spudger. Note the cable routing — take a photo for reassembly reference.
Transfer components to new screen
Move the earpiece speaker, front camera, proximity sensor, and any Face ID or fingerprint sensor components from the old assembly to the new screen. Use the correct screwdriver size for each tiny screw.
Install and test
Connect the new display cables, then temporarily reconnect the battery and power on. Test full-screen touch response, Face ID/fingerprint, proximity sensor, and True Tone before sealing. Apply fresh adhesive strips and press the screen into the frame.
