    I have bought a new iphone 7 which comes with ios 11 out the box and its causing issues on my phone.
    so I looked up on the internet and found that apple is still signing ios 10.3.3 for iphone 7.
    SO my Question is Can I downgrade to ios 10.3.3 from Itunes now?

    You can for sure as long as apple is signing it. FYI if you have a backup done on iOS11, you won’t be able to restore that backup on iOS10. Good luck.

    Do you mean 10.3.3? That would be yes. iOS 9 backup should work, too. You need to have *archived* the backup from the prior iOS version in order for that to work, otherwise the old backup was probably overwritten by iTunes.

    I backed up a few days ago
    That will work right?
    And did you select update option or restore option in iTunes?

    I think you’ll want to choose update; hopefully someone can corroborate that for me. Choosing restore will wipe your device, which is a huge pain unless that doesn’t matter.

    Update works from like 11.1 to 11.0.1, but you need to restore from iOS 11 to 10.x.

    But the fact that the iPhone came with iOS 11 leads a part of me to wonder if you could downgrade, even though the .ipsw is available.

    What issues? iOS 11 on my iPhone 7 Plus is perfectly fine. A few bugs here and there but nothing major.

    Yes, downgraded my iPad Pro 9.7" from 11.0.1 to 10.3.3. The only problem that I didn't backup my iOS 10 files so the iOS 11 backup was not compatible with iOS 10. Had to "Set up as new iPad".

    Ha ha...following the directions on a well-known Mac site (not this one), I did Option+Update. Did not work...twice. I then tried Option+Restore, and that worked like a charm. Took quite a while. Wiping it didn't really matter, since I had a very current archived backup.

    I would *guess* it would work, since the hardware was originally shipped with 10. No guarantee though...would be interested to hear how this works for the OP.

    Thanks, Option+Restore did it for me on my 6S as well.

    I'm giving my 6S to my wife (she has a 6 on 10.3.3), and wanted to have her experience the faster phone on 10.3.3 without any of the bugginess/changes of 11 (though 11.0.1 was pretty good on the 6S). So a full restore is what I wanted to do anyway, and I also followed directions that were wrong. With Option+Update I'd get the error "the iphone could not be updated unknown error 6". I also did it twice before I went searching here and found this thread :)

    That was exactly what happened to me. Glad it worked for you.

    It works, any device can install any iOS version as long as it’s being signed for that device.

    Good for you...however don’t pretend to be unclear about “what issues” as you can plainly see the plethora of issues with this pathetic not ready for prime time release.

    If you want to feel superior don’t post about it...just go stare at yourself in the mirror because you are not impressing anyone except yourself.
