How to unlock iPhone 6s

[1709]

I updated my iPhone 6s to new software ios 11. But, after finishing update, phone is just stucked on passcode screen. I can’t use touch screen anymore. Tried to unlock with Siri, but no response. Tried to hard reboot, googled every trick but all failed. Even tried to reset with iTunes, but no success.

Are you able to enter your passcode in? If that doesn’t work, try doing a hard reset by pressing both the home button and the power button.

You must enter your passcode before Touch ID can be enabled again.
