iOS 17 Bug: Apple Identifies Software Glitch Affecting iPhone 15 Series During Setup

Highlights

• Apple discovers a bug in iOS 17 that causes iPhone 15 and 15 Pro to get stuck on the Apple logo during initial setup.
• The issue is not confined to the iPhone 15 series but affects all devices running iOS 17 using the data transfer option.
• A temporary fix involves putting the device in DFU mode and restoring it through a computer.

Apple has pinpointed an iOS 17 bug that could potentially disrupt your iPhone 15 upgrade experience.

Specifically, the issue arises during the initial setup phase of new iPhones that come preinstalled with iOS 17.
The glitch is known to cause iPhones to get stuck in a boot loop, displaying the Apple logo on a black screen.

If your new iPhone 15 or iPhone 15 Pro encounters this bug during the data transfer process, you may find your device stuck on the Apple logo screen.

This issue is not limited to the new iPhone 15 series; it may also affect those who are switching to any phone that runs iOS 17 and uses the data transfer option.

The Fix: Using DFU Mode to Restore Your Device

To resolve the glitch, Apple advises putting the affected iPhone into DFU (Device Firmware Update) mode and initiating a restore via a computer.

To perform this, you need to connect the iPhone to a PC or Mac using a cable, press the volume up button, press the volume down button, and finally press and hold the side button until an icon appears, indicating that the device is in DFU mode.

Your device will then be recognizable through Finder on macOS or iTunes on Windows, where you have the option to click the ‘Restore’ button to reset the device.

Upon restoration, you can start the setup process from scratch.
A new software update may be available that will fix this iOS 17 bug, enabling you to safely transfer data to your new iPhone 15 or 15 Pro.

Caution for Older iPhone Models: iCloud Backup as an Alternative

However, for those upgrading to an iPhone model that predates the iPhone 15 series, a permanent solution for the data transfer bug has not been rolled out yet.

As a workaround, Apple suggests using iCloud Backup to update your new iPhone. Ensure your previous device has a recent iCloud backup (which can be forced via the phone’s settings) and then proceed with the ‘From iCloud Backup’ option during the setup of your new iPhone.

The information about this software issue and its workaround is elaborated in a support document released by Apple.
