    Will iOS 10.3.3 work on the new iPhone 8? Can the iPhone 8 be downgraded back to iOS 10.3.3.?

    Thanks!

    While I appreciate your succinct reply, can you expand on what prohibits this?

    Thanks!

    because it comes installed with iOS 11. if you don't believe us, feel free to try to find an iOS 10.3.3 ipsw for the iPhone 8 series.

    I believe you, I was just wondering why since you can downgrade iOS 11 back to 10 on an iPhone 7 or 6 for example. What prevents it?

    Since Apple has not released and will not release iOS 10.3.3 build ipsw's for iPhone 8, you cannot downgrade to iOS 10.3.3. New hardwares of new phones requires new drivers, and Apple include these drivers in the newest version of the software. Hope this clarifies.

    You cant do that either. iOS 10 isn't signed anymore. If you have 11, your stuck with it forever regardless of device.
