    Ok, so I went ahead to downgrade my iPhone 6S from the iOS 11 beta to iOS 10. Downloaded the image from the developer website, went ahead to restore it as I have done previously and boom. The restore fails. No error, nothing, just boots into recovery mode with the typical connect to iTunes screen. Ok, so I try again this time in DFU mode, same again happens, restore goes through, iPhone restarts and boots again into recovery mode.

    Literally don't know what to do. I have tried restoring to iOS 11, it doesn't let me. Different Mac, same problem. Any ideas?

    What version of iOS 11 beta were you on?

    OMG I managed to fix it. I restored the iOS 10.3.3 beta 6 image in DFU mode and it fixed it. I literally thought my phone was bricked for a minute.

    I just realized the 6s only has one version of beta 2. I have no idea what the problem is with that beta. You could try again or try getting a different IPSW for 10.3.2 or iOS 11 beta 1 (I heard this helps). If not maybe contact Apple.

    Edit: Good to see you got it fixed!

    Good to hear that you were able to restore your phone. Next step: put phone down, then Netflix & chill?

    i heard that there might be updated firmware in 11 which is supposed to happen with 10.3.3 and its not compatible with 10.3.2, thus the temporary brick
