Apple stops signing iOS 17.6.1, making it impossible to downgrade from iOS 18
Apple last week released iOS 18 to the public. The update comes with a bunch of new features, including customizable Home Screen and Control Center, a redesigned Photos app and improvements to the Messages app. However, those who have updated to iOS 18 can no longer downgrade to iOS 17, as Apple has just stopped signing iOS 17.6.1.
