This is a guide on replacing the front assembly on Apple iPhone 12
For the installation process we'll need the following tools.
- Heat Gun
- Suction Cup
- Plastic Pick
- Small Tri-Wing Screwdriver
The front assembly consists of the frame, the glass digitizer and the LCD screen.
You will need to replace the entire front assembly if any of these components are broken
To begin turn the phone off by holding the power button and confirming shutdown on screen.
Remove two pentalobe screws at the bottom of the phone.
Use a heat gun to warm the adhesive around the perimeter of the iPhone. Place a suction cup
near the bottom edge and while providing some tension insert a plastic pick between the display
assembly and the main body. Move it along the edge. Continue warming the device with a heat gun.
Apply some pressure with a plastic pick to separate the front assembly from the main body.
Go around the perimeter.
Please note, there are cables located near the left edge of the phone. Keeping that in mind open the
iPhone as a book to the left side.
Now we have access to the connectors shields. Using a Tri-wing screwdriver carefully remove 2 screws
securing the small metal shield. Remove the shield. Using plastic pick disconnect the battery connector.
Then LCD and touchscreen connectors. Using the same Tri-wing screwdriver remove four screws holding
a big metal shield. Using plastic pick open speaker and sensors connector. Separate the screen assembly
from the main body.
We will be replacing the waterproofing adhesive, so all of the original adhesive needs to be removed from the edge of the phone.
The waterproofing adhesive comes on convenient plastic sheets cut to the shape of the edge of the phone.
Remove the backing plastic of the adhesive shape. Apply the shape to the perimeter of the phone and using
plastic pick press the adhesive into place. Carefully remove the plastic making sure that the adhesive stays on the perimeter of the phone
Take out the new front assembly and put it to the left edge of the phone. Carefully reconnect the touchscreen connector, and LCD connector. Reconnect the speaker and sensors connector. Replace the big metal shield
and secure it with four screws. Reconnect the battery. Replace small metal shield and secure it with two screws.
Now we can test the device. Close the iPhone reconnect the charger and press the power button. The screen is working and we can finish the reinstallation process.
Close the phone tightly and using soft clothing apply some pressure to the sides of the phone snapping the display assembly in-place.
Replace two pentalobe screws at the bottom. Turn the iPhone on and we are done!
