To disassemble the iPhone XR you need the following tools:
• Screwdriver set • Tweezers
• Opening plastic tool • Plastic mediator
• Suction cup for removing display • Hairdryer
In the description of this video, I left links to the necessary tools and parts for replacement.
Before disassembling, turn off the iPhone and remove the sim card tray.
Unscrew two screws near the lightning port.
Using a hairdryer, heat the display surface for 1-2 minutes.
In this way, the glue heat between the iPhone case and the display, so it will be easier
to open the case.
Apply the suction cup to the bottom edge of the display and pull up on the ring.
Next, push the plastic mediator between the display and iPhone case.
If you cannot do this with a plastic mediator, take any thin plastic card and insert it between
the case and the display, then it will be easier to pry with a mediator.
Now, evenly and slowly, open the display around the perimeter of iPhone.
The iPhone case opens like a book; the display opens to the right side.
Using a Tri-Wing screwdriver, unscrew the 3 screws and remove the metal panel.
Now you can disconnect the battery cable from the mainboard.
Next, unscrew the 2 screws and remove the second metal panel.
Unscrew another 3 screws with a Tri-Wing screwdriver and two screws with a PH00 screwdriver.
Disconnect 3 cables of the display from the mainboard.
Unscrew 7 screws.
Disconnect the cable.
Disconnect the cable, which is located between the speaker and Taptic Engine.
Now you can remove the Taptic Engine from the iPhone case.
Now the speaker can be remove.
Note that the speaker glued to the bottom of the case.
To keep the factory adhesive tape, use a hairdryer to heat the place where the speaker glued.
