One of our users, Alex, messaged us saying that his iPhone 5 was acting funny after he updated to iOS 10, and he wanted to know if it was possible to downgrade to an earlier version of iOS. We figured a lot of people probably run into this issue so we thought we would make a video to help out! We will walk you through the process for iPhone 6 Plus and older, as well as iPhone 7. The process is a little different because the iPhone 7 has a solid state home button. Unfortunately you can only downgrade to a iOS that Apple is still signing, or authorizing.
