Downgrading from iOS 10 to iOS 9 – Possible or Not?

If you’re one of the people who have been anxiously searching the Internet, trying to see how you can downgrade from iOS 10 to iOS 9, then you’ve come to the right place. However, most likely the answer is not going to be one that you’ll like. The brief answer is that indeed, it is possible to downgrade, but this option is available only for a handful of people.

What Do You Need?

The downgrading option is available only for iPhones that are built on 32-bit architecture, which is the one that iOS 10 relies on. As such, you can downgrade only on the iPhone 5 or iPhone 5C. But that’s not all! Even if you do have one of these phones, only the people who saved the SHSH blob files at the moment when they updated to iOS 9 can do it. If you don’t have the files anymore, you can kiss the downgrade goodbye.

What Are Those Files?

Briefly put, the SHSH blob file represents a small file, in essence a digital signature made by Apple in the moment you update your phone. It is a tool for controlling the versions of the iOS you are allowed to install on the device. The iOS 10.3.2 and 10.3.1 wear the Apple signature, but if you try to restore the device to a different version, it won’t allow you.

The jailbreakers saved the SHSH blob file regularly. As such, if you still have the SHSH blob file from the time when you installed the iOS 9, then you can still downgrade from iOS 10. Even so, it’s not going to be an easy process, unless you are savvy enough to go through it all and you also have the necessary tools for it.
