If you are unboxing an iPhone 15, iPhone 15 Plus, iPhone 15 Pro, or iPhone 15 Pro Max today, make sure to update the device to iOS 17.0.2 before transferring data to the device from another iPhone, or else you
might encounter issues.
iOS 17.0.2 is only available for the iPhone 15 lineup. Apple
says the update fixes an issue that may prevent transferring data directly from another iPhone during the device setup process, so installing it is very important. The update should appear during the setup process, or it can be installed via the Settings app under General → Software Update if you proceeded to set up the device as new and transfer data later.
If you already attempted to transfer data from another iPhone before updating to iOS 17.0.2, and your iPhone 15 is now stuck showing an Apple logo, Apple has shared a new
support document with steps on how to restore the iPhone:After restoring the iPhone 15 and updating it to iOS 17.0.2, the process of transferring data from another iPhone can be restarted.
