iphone 6s won’t update to ios 11

Update the iOS on your iPhone, iPad, or iPod touch - Apple Support

Also:

• If you're updating over the air, be certain you use Wi-Fi, not cellular data.
• If you're using iTunes, be certain you use iTunes 12.7.

• Actually, the original poster said he solved the issue on Oct. 3, 2017.
• It's very unlikely that the article you referenced is a solution for anybody, as being a beta tester would be a prerequisite for this to work.

I'm having the same kind of trouble too.

I had the same issue. I restarted my phone and the option to upgrade was available. Hope this helps...

And it never will.

This fourth generation iPad cannot be updated past iOS 10.3.3.

I have the same issue as well I have an iphone 5c and i tried restarting didnt work, tried connecting to Itunes which is the most updated version still no update. any ideas what to do?

Yes!

Either give up on updating or purchase a newer iPhone.

The iPhone 5C cannot be updated to iOS 11. An iPhone 5S or newer is required.

I can not get the latest iPhone update 11. I have 10.3
