Apple has stopped signing iOS 18.1.1 and blocks downgrades from 18.2.

Apple stopped signing iOS 18.1.1 on Thursday, preventing users from downgrading their already functioning iPhone or iPad to this version of the operating system. This move follows the release of iOS 18.2 a week ago, which introduced important new features and improvements.

Because iOS 18.1.1 is not signed, users of iPhones and iPads cannot return to this version of the operating system. iOS 18.1.1 was released on November 19, 2023, with important security patches.

iOS 18.2 was released on December 11 and introduced many new features. These include Image Playground, Genmoji, integration of Siri and ChatGPT, improved camera control, and email classification. Of course, this update also includes multiple security patches to prevent access by malicious apps to private information.

Apple's decision to stop signing iOS 18.1.1 aligns with its commitment to user security. By encouraging updates to the latest version, Apple aims to protect devices from potential vulnerabilities.

The inability to downgrade affects the remaking community. Reverting to older iOS versions is often done for this purpose. Some users may be unhappy about not being able to downgrade, but Apple's policy of stopping the signing of old iOS versions is a long-term practice aimed at maintaining the security of its ecosystem.

Users are strongly recommended to update their devices to iOS 18.2 to ensure the latest security patches and feature improvements. This can be done by opening the Settings app, selecting "General" > "Software Update".

Users of devices running iOS 17 can receive security patches without upgrading. However, upgrading to iOS 18 will prevent them from reverting to iOS 17. If a device is running iOS 18.3 beta, it can only be downgraded to iOS 18.2.
