If you’ve updated your iPhone to iOS 18.4.1, there’s no turning back now. Apple has officially stopped signing iOS 18.4.
Downgrading From iOS 18.4.1 to iOS 18.4 is No Longer Possible
Why the rush to move on from iOS 18.4? According to Apple, the iOS 18.4.1 update includes critical security fixes, including one vulnerability that was being actively exploited. It also resolves a glitch with wireless CarPlay, which had been causing headaches for some users.
For those keeping score, this means that downgrading from iOS 18.4.1 is now officially off the table. If you’ve already updated, you’re locked in. And if you haven’t updated yet, now might be a good time to do so, especially considering the security patch baked into the update.
Apple regularly stops signing older iOS builds shortly after releasing a new one. It’s all part of the company’s standard software strategy to keep users on the latest, most secure version of iOS. Once a version is no longer “signed,” Apple’s servers won’t allow it to be installed on any device.
Apple hasn’t said when we can expect iOS 18.5 and iPadOS 18.5, but with WWDC around the corner, there’s a chance we’ll get a sneak peek soon. Until then, make sure you’re running the latest version to stay protected.
