Apple no longer signs iOS 16.4: restoration and update blocked

Apple has stopped signing iOS 16.4 to its servers. This means that it is no longer possible to install this version on your iPhone or iPad, either as an update or a restore.

Apple released the stable version of iOS 16.4 on March 28. This one had the right to several new features:

• 21 new Emoji including animals, hand gestures and objects are now available in Emoji Keyboard.
• Notifications for web apps added to the home screen.
• Voice Isolation mode for cell calls emphasizes the sound of your voice and blocks out surrounding noise.
• The Duplicates album in Photos now supports detecting duplicate photos and videos in an iCloud shared photo library.
• VoiceOver is now supported for maps in the Weather app.
• Accessibility setting to automatically darken video content in which flashes or strobes are detected.
• Visual search is now available in Belgium and Switzerland.
• Fixed an issue that could prevent children’s purchase authorization requests from displaying on the parent’s device.
• Fixed an issue that could cause Matter-enabled thermostats to become unresponsive after pairing with Apple Home.
• Crash detection optimizations on iPhone 14 and iPhone 14 Pro.

We then had the right to iOS 16.4.1 on April 7. This one, which is the latest and obviously signed by Apple, was lighter. It fixed two bugs (one with emojis and one with Siri) and closed security vulnerabilities exploited by hackers.

The next version will be iOS 16.5. Apple has already offered two betas to public developers and testers.
