How to Fix iPhone Stuck on Diagnostics and Repair Screen?

iPhones are well-known for their reliability and performance, but even the most robust devices can experience technical issues. One such problem is when an iPhone gets stuck on the “Diagnostics and Repair” screen. While this mode is designed to test and identify problems within the device, being stuck in it can render the iPhone unusable. This guide will walk you through the process of understanding diagnostics mode, how to run diagnostics, and how to resolve if you iPhone is stuck on diagnostics and repair screen.

1. What Is iPhone Diagnostics Mode?

iPhone Diagnostics Mode is a specialized tool embedded in iOS designed for troubleshooting hardware and software issues. This mode provides detailed information about the device’s performance, including battery health, connectivity, and internal hardware status.

Apple and authorized technicians primarily use diagnostics mode during repairs or servicing to identify malfunctions without opening the device physically. However, diagnostics mode may sometimes activate unexpectedly or fail to exit properly, causing the phone to freeze on the “Diagnostics and Repair” screen.

2. How to Run Diagnostics on iPhone?

Running diagnostics on your iPhone can help you determine if there’s an underlying issue with your device. Here’s how you can initiate diagnostics:

2.1 Using Apple Support App

• Get the Apple Support app and install it on your iPhone.
• Navigate to Get Support > Device Performance Issues > Run Diagnostics and Start Sessoin.
• Start the diagnostics on your device by following the on-screen prompts.

2.2 Through Settings

• Navigate to General > About by opening the Settings panel.
• If your device detects any hardware issues, it will display a Diagnostics & Usage option, where you can perform a test.

2.3 Via Remote Support

Contact Apple Support, and they may guide you to a URL (e.g., https://getsupport.apple.com/self-service-diagnostics) where you can run a diagnostics test remotely.

2.4 Using a Combination of Buttons

Restart the iPhone and hold specific buttons (like the volume and power buttons) when prompted to enter diagnostics mode. This option is generally for advanced users or technicians.

While these methods are helpful for troubleshooting, problems arise when the diagnostics mode becomes unresponsive.

3. How to Fix iPhone Stuck on Diagnostics and Repair Screen?

If your iPhone is stuck on the “Diagnostics and Repair” screen, follow these steps to restore functionality:

3.2 Update or Restore via iTunes/Finder

Connecting your device to a computer and using iTunes (or Finder on macOS Catalina and later) can help resolve software issues.
