Apple officially blocks users from downgrading to iOS 18.0.1

Apple released iOS 18.1 on October 28, and a week later, Apple stopped signing iOS 18.0.1. This move did not come as much of a surprise to iOS users as Apple often stops signing older iOS versions to prevent users from downgrading. When an update is locked, it cannot be installed on an iPhone due to server-side software verification.

Apple officially blocks users from downgrading to iOS 18.0.1.

According to Apple's notes, the iOS 18.0.1 update addresses issues related to the touchscreen, camera, and Messages app.

Specifically, this update provides important bug fixes and security updates for your iPhone including:

The touchscreen may become temporarily unresponsive in certain situations on iPhone 16 and 16 Pro.

The camera may freeze when recording macro mode video on the ultra-wide lens at 4K resolution with HDR turned off on iPhone 16 Pro models.

Messages may unexpectedly exit when replying to a message using a shared Apple Watch face.

Thus, when users have upgraded to the latest iOS 18.1 version, they cannot downgrade to iOS 18.0.1.

Apple prevents downgrading to older versions of iOS to encourage iPhone users to keep their operating system up to date with the latest security fixes.
