Apple on Friday ceased signing of code older than iOS 13.1.1, following this week’s release of iOS 13.1.2, which patched a small number of issues on the iPhone.
Today’s cease to signing iOS 13.1.1 code comes just one week after the Cupertino firm released the iOS 13.1.2 update to close a security hole that granted third-party keyboards “full access” to iOS assets without user approval.
The iOS 13.1.2 update:
– Fixed a bug where the progress bar for iCloud Backup could continue to show after a successful backup
– Fixed an issue where Camera may not work
– Addressed an issue where the flashlight may not activate
– Fixed a bug that could result in a loss of display calibration data
– Fixed an issue where shortcuts could not be run from HomePod
– Addressed an issue where Bluetooth may disconnect on certain vehicles
As well as iOS 13.1.1, Apple stopped signing for iOS 12.4.1 released in August, and iOS 13 and 13.1 from September.
Users can now no longer download and install iOS 12.4.1, iOS 13, iOS 13.1 or iOS 13.1.1 from Apple’s servers. This restricts device owners to installing iOS 13.1 and iOS 13.1.2 on their devices.
