Steps to Install the Diagnostic-Compatible Soft OLED Screen

1.Ensure the device is updated to the latest iOS version.
For example, iOS 18.5 or later.

2.Install the TPH diagnostic-compatible soft OLED screen.

• • No IC transfer is required.
  • Do notprogram True Tone data — otherwise, the diagnostic process will fail.
  • It’s a simple plug-and-play

3.Determine the screen type:

1. • If the screen comes with a front sensor:
   • Connect boththe screen and the front sensor cables.

If the screen does not come with a front sensor:

• Only connect the screen. Do not connect the front sensor until after the diagnostic process is complete.

4.Connect the device to Wi-Fi.

5.You may see a pop-up saying “Finish your display repair.”

• • If you do, tap it.
  • If not, go to:
    Settings → General → About → Parts & Service History

6.On the “Parts & Service” page, tap
Restart & Finish Repair

7.Follow the on-screen instructions in the Apple Repair Assistant.

8.Once the device restarts and the process is complete:

• • You should no longer see any warning or pop-up messages.
  • If your screen didn’t come with a front sensor, now is the time to plug it in.
  • The original front sensor is essential, replacing it will make the diagnostic result invalid.
  • Make sure the device is powered off, connect the sensor cable securely, and then restart the device.
