How to Downgrade iOS 11

Apple officially launched iOS 12 for the public with new features like Memoji, screen time, shortcuts, and many more, including better performance and consistency. Whenever Apple launches a significant new iOS upgrade, it is fascinating, so, understandably, the normal inclination is iOS 12 to instal.

If you have iOS 12 enabled, but would like to uninstall it again to iOS 11.4.1, we have protected it because it’s bloated or draining battery life. It is effortless to update iOS 12 to iOS 11.4.1 as Apple already signs the iOS 11.4.1 firmware.

It can only be downgraded to iOS 11.4.1, the new iOS 11 update. As Apple has stopped the outdated iOS firmware files, you can no longer be downgraded to previous versions.

Please remember that the procedure entails cleaning and then rebuilt from a copy, so it will take some time to rebuild the data and your internet connectivity (when you restore your iCloud backup) depending on how much data you need.

See this page for details as to whether Apple still signatures the firmware log. Apple also signs the firmware file with green tick rows and will downgrade from iOS 12 to iOS 11.4.1.
