Thought I'd add my bit here.
Had the same issue, tried a different screen from what was installed (better quality) but same thing.
Hard reset - Same thing
Put a genuine screen on - works.
So installed all the small parts on the damaged genuine screen, fitted it, put in dfu mode and reset/updated to 11.02.
Removed the screen, done the usual replacement, and worked..... for 10 seconds.
Got into contact of the manufacturer i deal with, and hats off, they responded back promptly late into the evening, and was trying all sorts their end.
This is what they sent me:
"After upgraded the iPhone to iOS 11.0 (The touch not work) , our factory has tried many times with different methods with different mobile phone this afternoon , and the solve method is upgrade your phone system to iOS 11.02 (Not 11.0 or 11.1) .
Also the testing details as below :
1. Upgrade to iOS 11.0 : Touch not work . We must replace original or refurbished LCD , then it is ok
2. Upgrade to iOS 11.01 : Touch not work . If we make Hard Reset , the touch would be work for few seconds or keep working to the screen power off . Then , the touch not work again and need to hard reset again .
3. Upgrade to iOS 11.02 : Touch work good .
So we suggest update to iOS 11.02 version ."
Done what they said for 11.02 which we a battery pull and power cycle as such, and it worked, until the phone woke up from sleeping.
Thus bit threw me off, as I was doing this with the after market screen which the phone originally had on, so swapped it over to the ones I buy off the manufacturer, done it again, and after sleeping/waking/powering off & on. It still works!
Hopefully this may help someone with this issue, because this was giving me a right headache, cancelled all other Repairs, and wasn't sure if my stock was effectively useless!

i got the same problem too.
Ios 11 killed my 6s screen.
So sad i can't update my 6s to ios 11.
i read some articles from google, may be 6s need to turn off the 3D touch first before doing the ios 11 update.

I have the same issue.
I tried restarting, rebooting, restoring to factory defaults, and I tried to go back to the 10.3.3. version but iTunes won't allow the install. It gets almost to the end and then gives an error code. I've spend 6 hours trying all of Apple's suggestions. Now I'm going to go into Apple and see what they can do.
