    I have OSX 10.9.5, itunes 12.6.2.20 and iphone 6S with 11.0., which I'm really hating right now because of how the battery is draining so much, apps just freeze, phone retarts itself and the list goes on. Before I updated to 11.0.3 I did backup my IOS to 10.3.X ( cannot remember the last IOS I was on before I upgraded to IOS 11). Went online to see a few tutorials on how to downgrade from IOS 11 to 10.X.X by downloading IPSW file 10.3.3, 10.3.2 and 10.3.1 with no luck im stuck in itunes restore.

    I had my iphone plugged into itunes and I held down options key and click upgrade to select my IPSW file, which i picked 10.3.3. It extracted the file and look like it was going to update then itunes gave me a error of "iphone could not be updated, decline to authorize this image on this device for user". pretty much i have a brick phone. I dont want to restore it to IOS 11.0.3 im afraid ill permantely be stuck on ios 11 and cannot go back at all.

    anyone have any ideas? i saw this program called recboot but looks kind of shady.
    But then again a fresh install might do the trick of iphone6s acting up.

    Try IOS 11.1 public beta 3.....or if you insist on going back to 10.3.3, put you phone to DFU first and than choose the downloaded 10.3.3. That way you should be able to restore to it.

    Put your iPhone in DFU mode

    1. Plug in your iPhone, iPod touch, or iPad to your Mac or Windows PC.
    2. Make sure iTunes is running.
    3. Turn Off your iPhone, iPod touch, or iPad if it isn't already.
      1. Press and hold down the On/Off button on the right side of the device for 3 seconds.
      2. Swipe the slide to power off slider to the right.
    4. Press and hold down the On/Off button on the right side (iPhone 6 or later) or top (all other iPhones, iPods, and iPads) of your device for 3 seconds.
    5. Press and hold down the Home button on the front of your device while stillholding down the On/Off button.
    6. Keep holding both buttons down for 10 seconds. (If you see the Apple logo, you've held them too long and will need to start again.)
    7. Let go of the On/Off Button but keep holding the Home button for about 5 seconds. (If you see the "Plug into iTunes" screen, then you've held it too long and will need to start again.)
    8. If the screen stays black, that's it! Your iPhone should now be in DFU mode.
    At this point, iTunes should show you an alert saying it's detected your iPhone and will allow it to be restored.


    You should see black screen (without iTunes logo, if you see the logo, you are in recovery mode and should try again).

    Click on the Alt/Option key on Mac and than restore button in iTunes and select 10.3.3 ipsw.

    It sounds like there's some kind of error connecting to the signing server.

    He got it to work because iOS 10.3.3 was still being signed November 4th 2017. It’s not signed anymore so it’s not possible to downgrade.

    You should get your device looked at.
