It just got that much harder to revert from iOS 10 to iOS 9.

Apple has stopped signing iOS 9.3.5, effectively preventing anyone already on iOS 10 from downgrading to iOS 9.

The company has stopped digital signing on iOS 10.0.1, making the latest versions of iOS —iOS 10.0.2, and 10.0.3 on the iPhone 7 and 7 Plus the only releases anyone can install without unsupported workarounds.


This isn’t unusual and Apple regularly stops signing updates as a security measure. Still, this could theoretically cause problems for anyone wishing to revert from iOS 10 to iOS 9 on an older. New versions of iOS typically don’t perform as well on devices that are several years old —some tests have suggested though that iOS 10 is friendlier in this regard than past updates.

Separately, Apple has stopped signing tvOS 9.2.2 for the fourth-generation Apple TV. tvOS 10 introduced features like a dark mode, and upgraded Siri and HomeKit functions.
