Apple blocks iPhone users from downgrading to iOS 18.4.1

Apple officially stopped signing iOS 18.4.1, thereby preventing iPhone users running iOS 18.5 from downgrading to this old iOS version.

Apple blocks iPhone users from downgrading to iOS 18.4.1

Apple typically stops signing an iOS version within a week or two of releasing a new version of iOS. When an update is stopped signing, iPhone users will no longer be able to install it due to server-side software verification checks.

And this time too, just about 1 week after releasing the iOS 18.5 update, "Apple" has officially locked the iOS 18.4.1 sign. This policy is to encourage iPhone users to upgrade to the new operating system, to ensure security improvements.

iOS 18.5 adds new wallpapers, changes to Screen Time passcodes for parents, and support for carrier-provided satellite features on ‌iPhone‌ 13 models. The update also addresses more than 30 different security vulnerabilities.

Experts also recommend that iPhone users should update to iOS 18.5 as soon as possible, especially if they are using previous versions of iOS 18, which have many weaknesses in the security layer.

Thus, when iPhone users have upgraded to the latest iOS 18.5 version, they will no longer be able to downgrade to iOS 18.4.1.
