Apple stops signing iOS 15.4.1 after releasing iOS 15.5

    On Monday, Apple stopped signing iOS 15.4.1, just a week after iOS 15.5 was released to the public. As a result, iPhone and iPad users can no longer downgrade from iOS 15.5 to iOS 15.4.1, which will affect users who have jailbroken their devices.

    iOS 15.4.1 was released on March 31 with general fixes, including fixing a bug that caused the battery to drain faster. On May 16, Apple released iOS 15.5 – which comes with improvements to Apple Cash and new features in the Podcasts app.

    You can check out all the new features included in iOS 15.5 below:

    • Wallet now allows Apple Cash customers to send and request money from their Apple Cash card
    • Apple Podcasts includes a new setting to limit episodes stored on your iPhone and automatically delete older episodes
    • Addressed issue where home automation, triggered by arrivals or departures, may fail

    iOS 15.5 also fixes many security breaches. This exploit could lead to malware executing arbitrary code with kernel privileges in the operating system. This is the main reason why Apple doesn’t allow users to downgrade their devices, as older iOS versions are more vulnerable to security exploits.

    Reverting to older iOS builds are commonly used by people who have jailbroken their iPhones and iPads. Restoring an Apple device to a previous version of iOS can also sometimes be helpful for users who experience significant errors after upgrading to the latest iOS version.

    Unfortunately, if you run into any issues with iOS 15.5, you will now have to wait until a future update is available rather than downgrading to iOS 15.4. It’s worth noting that Apple has been beta testing iOS 15.6, which is expected to be released to the public in June.
