You may get excited with the launch of iOS 10 and take the opportunity to immediately upgrade your iPhone to iOS 10. However, subsequently you may find that iOS 10 is not your taste or is causing many issues on your phone. The iOS 10 has, like any beta, many bugs and it is one of the reason that we don't recommend common users to update their iOS devices to the beta version.
In this guide, we will show you how to downgrade iOS 10 to iOS 9.3.5 so you can run your device under a smooth operating system.
Waning: The process will wipe all data on your iPhone/iPad, so make sure you have a backup from when you were on iOS 9. That's because you could not restore a backup made on a new iOS beta to a device running an older beta.
