Can't downgrade from iOS 11

[xoxor]

Hello, I have recently tried iOS 11 on my iPhone 6S but I decided to downgrade to iOS 10. I have El Capitan with iTunes 12.6.1. Progres bar on my iPhone its not at the end, but iTunes says "iPhone has been restored" and after iPhone reset I get error message in attachements.

What should I do? I tried instal it 5 times, but its still the same.

Next time check the beta thread, this is a common issue in beta 2. Either downgrade to beta 1 and then redowngrade to iOS 10 or go to the Apple Store. You could also just try going to the public beta and then downgrade

go to the Apple Store.

This might be an unpopular opinion but I think that the Apple Store should turn away people that come in with a bricked device on iOS 11. Unless you know how to DFU Restore, you shouldn't be installing iOS x.0 betas in the first place. Also there's a 15 page thread on this exact issue in the iOS 11 forum. https://forums.macrumors.com/threads/cant-downgrade-from-11-beta-2-to-10-3-2.2052583/
