Apple officially blocks iPhone users from downgrading to iOS 18.6.2

Apple has just officially stopped signing iOS 18.6.2, thereby preventing iPhone users running iOS 26 from downgrading to this old iOS version.

Apple has stopped signing iOS 18.6.2, cannot downgrade to iOS 26.

iPhone manufacturers often stop signing an iOS update within a week or two of releasing a new iOS version. When an update is stopped signing, it will no longer be available to iPhone users due to server-side software verification checks.

And this time too, just over a week after releasing the iOS 26 update, Apple has officially locked the sign 18.6.2. This policy is to encourage iPhone users to upgrade to the new operating system, to ensure security improvements.

iOS 26 is a major update, bringing a host of new features focused on personalization, performance, and privacy. It introduces improvements to Siri with better natural language processing, customizable app icon options on the home screen, and more powerful interaction widgets.

In addition, iOS 26 also focuses on protecting users, with the addition of advanced security features, better privacy controls, and fixes for dozens of potential security vulnerabilities. Apple also improves the ability to sync between devices in the ecosystem, providing a more seamless experience.

Experts also recommend that iPhone users should update to iOS 26 as soon as possible, especially if they are using previous versions of iOS 18, which have many security weaknesses.

Thus, when iPhone users have upgraded to the latest iOS 26 version, they will no longer be able to downgrade to iOS 18.6.2.
