It is no secret that iOS 9 is now available officially to the public. If you know that, you should also be aware that many users have already installed the firmware on their device. iOS 9 has been called the greatest iOS version to be ever released to date, with a load of new features. However, some users may be experiencing bugs they can’t handle.
Downgrade iOS 9 to IOS 8.4.1
Others may be facing performance issues on older iDevice hardware, such as hanging user-interfacing and crashing applications. If you are someone who has been experiencing such issues since you update your device, or just simply don’t like the new firmware, you can read this guide to go back to iOS 8.4.1.
The steps mentioned below will walk you through the process of downgrading the firmware on your device to iOS 8.4.1, which is the latest build of iOS before iOS 9 came on the horizon. It should be noted that the process will work as long as the iOS 8.4.1 firmware is being signed by Apple. After Apple stops signing the firmware, which could be any day, there would be no way to downgrade.
