• iOS Update Errors: If an update is interrupted or corrupted, it can trigger an iPhone 17 loop.

Backing up ensures your photos, contacts, messages, and apps are safe even if your device has an iPhone 17 bootloop.

Step 1: Open Settings > General.

Step 2: Scroll down and tap Transfer or Reset iPhone > Reset.
