    So my iphone 6 stuttered alot in ios11 to the point it was too unberable, so i decided to revert back to 10.3.3. Now the problem i have is when i run any application, it'll just freeze and stay at the app's loading screen for like 1 minute untill the "loading wheel" shows up and i have to unlock the phone again. I tried upadting apps, deleting and installing them again and nothing works. Not even the phone app - it just crashes untill it reboots itself, or if i'm lucky, goes back to main screen sometimes. Anybody knows what to do?

    if you backed up/synced after upgrading to ios11, you wont be able to restore that to ios10. Usually it creates a separate backup when you upgrade but that's not always the case.

    Backups only work on the corresponding iOS version they were made on. So if you backed up your phone on iOS 11 and try to restore to that backup while on iOS 10, it won’t work.

    What you could do is update your phone again to iOS 11 and restore the backup you had. Then save all of your photos to your computer. Then you could go back to iOS 10 and then sync your photos back. At least your photos wouldn’t be lost.

    As suggested, check to see if and how many local backups you have in iTunes and when they are dated. If you upgraded while connected there’s a good chance iTunes will have kept a local copy of the backup just before you upgraded, but you will have had to have been connected when updating for it to save a local copy.

    If you’re restoring from an iCloud backup, iCloud only saves the most recent backup, which in this case is probably iOS 11 unless it was overwritten.

    Turning on “iCloud Photo Library” means your entire library is backed up in iCloud, so you won’t necessarily have to copy them to Photos and then re-sync them to your phone. It will re-sync your entire library when signing in to iCloud after you’ve re-installed the phone. iCloud is a useful extra backup for photos and helps you to keep in sync.

    It sounds like your best bet may be having to go back to iOS 11 and restoring from that backup, but make sure you turn on iCloud Photo Library and let all your photos sync to iCloud before downgrading again. Assuming you have enough space available in iCloud that is.
