    I update to iOS 11 and it really messed up my phone. I tried to restore it using iTunes but it didn't help. I got a new phone under warranty and it has iOS 10.3.3. If I use the back up on my iTunes to restore my contacts (cause they are gone) will it upgrade my phone to iOS 11? I want to restore phone from iTunes and put my music and contacts back, but not upgrade to iOS 11. But last back up was when I had iOS 11. Its an iPhone 7 Plus

    Welcome to iPhone Forums!

    You can’t use the backup of your previous iPhone, running iOS 11, on your current one on iOS 10.3.3, if you don’t intend to update it. That’s not possible.
    It would be different, if it were the other way round: a backup made with a previous iOS version can be used on a device with a later one installed.
