Following the public release of iOS 15.5, Apple has stopped signing iOS 15.4.1. This means that all iPhone, iPad, and iPod touch users can not downgrade their devices to iOS 15.4.1 version.
Last week, Apple seeded iOS 15.5 update to the general public which included new features, improvements, and security fixes. Therefore, it is Apple’s usual policy to stop signing older versions of iOS when the new version is released to make sure that users have the latest version of iOS to enjoy new features, performance improvements, and more importantly, security patches.
The company also stop signing older software versions to discourage jailbreaking because users who jailbreak their devices can not immediately upgrade to a new iOS release. Until a jailbreak is available for the latest iOS version, jailbreakers have the option to either stay on the older version or update.
Apple no longer signs iOS 15.4.1 version
In April 2022, Apple seeded the iOS 15.4.1 update for compatible iPhone, iPad, and iPod touch models which included bug fixes for the battery drain issue and connectivity issues of braille devices and MFi hearing devices.
Now, the tech giant has stopped signing iOS 15.4.1 which prevents users from downgrading their compatible devices from iOS 15.5. And if an iPhone, iPad, or iPod touch needs to be restored, the device will be upgraded to iOS 15.5 which is currently the latest stable version.
iOS 15.5 update includes new features like a new “automatically download” on the Podcasts app to configure a “download and keep” option for the number of podcasts, a “send and request” button for Apple Pay Cash in the Wallet app, support for third-party Reader apps to add links to external websites, Photos app now ignores sensitive locations in the Memories feature, return of playback control support to the Apple Music API, support for the “Communication Safety in Messages” in U.K. and Canada, and Wi-Fi signal bars in the Home app.
