Software tools
A System Configuration step may be required at the end of your repair. System Configuration is a postrepair software tool that completes the repair for genuine Apple parts. Running System Configuration has a number of purposes that vary based on the part replaced.
TrueDepth Camera Configuration is used after a TrueDepth camera repair.
What System Configuration does | Why it's important |
|---|---|
Transfers factory calibration values | Certain parts like displays, cameras, and ambient light sensors have calibration values that are customized to each individual part during manufacturing. Transferring these values ensures maximum performance and quality after a repair. |
Links Secure Enclave and biometric authentication parts | After repair of a logic board or a biometric authentication part (Touch ID or Face ID ), linking the biometric sensors to the Secure Enclave on the logic board is required to ensure device security. |
Ensures repair integrity | After a hardware repair, software checks are performed to ensure repair integrity. Repair integrity means that a genuine Apple part has been correctly installed. |
Assigns wireless region | To comply with regional communications regulations, a wireless region must be assigned to your logic board. |
Updates firmware | Keeping firmware up to date ensures that the device has all the latest security and performance features. |
System Configuration requirements
The minimum requirements for System Configuration include:
The latest version of iOS—not a beta version—on the iPhone
A strong Wi-Fi network capable of 1.0 Mbps download and upload speeds, with less than 400 ms latency and less than 2% packet loss. Estimated data usage to run System Configuration is 6–22 MB.
If the TrueDepth camera is replaced, System Configuration also requires:
A Mac with the latest version of Apple Service Utility installed. You’ll also need to install iPhone Repair – TrueDepth Camera resources, located in the Apple Service Utility Resources window.
Internet access for the Mac
A Lightning cable for iPhone 14 and earlier or a USB-C charge cable for iPhone 15
How to initiate System Configuration
Depending on the part replaced, you will initiate System Configuration through one of the following two methods:
Put the device into diagnostics mode. Tap Start Session and follow the onscreen prompts.
