Apple Stopped Signing iOS 15.4 A Week After The Release Of iOS 15.4.1.

Apple has stopped signing iOS 15.4 and restricted users from downgrading to the latest iOS version. Instead, Apple encourages users to upgrade to iOS 15.4.1. Apple stops signing older iOS versions to avoid jailbreaking. Users cannot downgrade or update their iOS devices after an iOS version is unsigned.

Along with iPad OS 15.4, macOS Monterey 11.3 and watchOS 8.5, the iOS 15.4 update was also released. The update introduced the ability to unlock iPhones using FaceID even when wearing a mask. The update also caused battery draining issues for some iPhone owners, which Apple corrected with the release iOS 15.4.1.

Apple also contained a fix to a zero-day security vulnerability in iOS 15.4.1. This fix was made available in Apple AVD media framework. According to the company, it was aware of the vulnerability and had taken steps to fix it. Users have good reason to upgrade to iOS 15.4.1.

Apple has also stopped signing iOS 15.4 and Home Pod Software 15.4, as reported from Mac Rumors. The company has also stopped signing iPad OS 15.4.

Apple will only sign a limited number of iOS versions at one time in order to stop jailbreaks and prevent users from downgrading. This move encourages users to use the most recent operating system for their iPhone, which has the latest security patches. They cannot move to an older version. It reduces security risks and third-party attack.

Some people find it annoying to have to stop signing older versions of software. This prevents them from returning to the original experience if they aren't satisfied with the new features.
