How can I unfreeze my iPhone stuck on the Apple logo after an update?

If your iPhone stuck on Apple logo and loading bar, using Finder is a reliable free method to resolve the issue, especially if you're using a Mac with macOS Catalina or later.

Using Finder to update your device is effective for several reasons. It bypasses the phone's normal startup process to access a separate recovery system. This allows your computer to fix corrupted system files caused by a failed iOS update or other software glitches.

Selecting Update will attempt to reinstall iOS without deleting your data, which is ideal. The process will download the necessary software and reinstall the operating system, hopefully resolving the stuck screen. If the update doesn't work, you might need to choose Restore, which will erase your data but can fix more stubborn issues.

To fix an iPhone stuck on Apple logo and loading bar via Finder is a completely free and effective method that leverages built-in tools on your Mac without needing any third-party software.
