Most Apple's iPhone, iPad and iPod touch users might have upgraded their devices to the latest software iOS 9, which comes with several cool features. But there is no guarantee that the new OS will work perfectly fine on all devices. There are chances of some devices having issues with the new operating system like in the case of iOS 8 last year.

So, what do you do if you have upgraded your device to iOS 9 and are not happy with it and want to downgrade to iOS 8.4.1? You can revert back to the older version as long as Apple continues to sign the older OS.

The Cupertino-based giant has stopped signing iOS 8.4 firmware files, which means users can't downgrade their devices, but it still signs iOS 8.4.1 till the time of filing this report. So, you can downgrade your device to older firmware as long as Apple signs it.

Important points to remember before downgrading

  • Downgrade to iOS 8.4.1 as soon as possible because Apple may stop signing the firmware any time. If you get "This device isn't eligible for the requested build" message, you have either downloaded the wrong file or Apple has closed the window for the software.
  • Make sure that you backup your device to iCloud or using iTunes because iOS will delete all apps and data while reinstalling an older version of firmware. IBTimes India will not be held liable for any damage to your device during the process.
  • Downgrading should be done at one's own risk as Apple doesn't recommend it.
