You didn't mention you tried to set up TID after installing 8. Did You? If not that's why you are getting the Failed message.

iPhone 5s: Using Touch ID

TouchID will not work

• After restarting your iPhone 5s
• When more than 48 hours have elapsed from the last time you unlocked your iPhone 5s
• To enter the Touch ID & Passcode setting

You'll need the passcode then your registered fingerprint(s) will work.

My iPhone 5s was purchased Nov 2013 and I setup Touch ID at that time and it has been functioning without any problem until Mon 15 Sep when I was running iOS 7.1.2 - I had not made any changes to the iPhone but the functionality just stopped working

The iPhone unlock and the iTunes & App Store unlock were off but on each attempt to activate these I receive a Failed message - unable to complete Touch ID setup

I have tried a hard reset but this did not resolve the issue

Today I successfully upgraded to iOS 8 and I thought that this would restore the functionality of Touch ID but unfortunately that is not the case - same error message when trying to activate the iPhone lock

The passcode is active and continues to function and has not been changed since originally set Nov 2013

Can anyone assist in re-activating the Touch ID functionality ?

It sounds as if you may have a hardware failure.

Make an appointment with the Genius Bar at your local Apple Store.

Thanks for your reply - it will be the Saturday before I can do that

In the iOS 8 setup it did not mention Touch ID.

Now i am currently on iOS 8 and Touch ID appears in Setting , but when i try to turn on iPhone Unlock or iTunes it says : "Failed , Unable to complete Touch ID setup.Please go back and try again."

Do you know why?

When you go to 'Add a Fingerprint...' does it take you to the next screen where it says 'Place Your Finger'? If so what happens when you place your finger on the Home button? It should give you a number of prompts as it learns your fingerprint.

I can't see any of your images as they don't load for me. If it's a software glitch you could try doing a restart and reset. If that fails try doing a restore. The other thing is as the problem seems persistent even after the update to 8 you might have a hardware problem. I'd have it checked out at an Apple Store or an Apple Authorized Service Center.

Turn your iOS device off and on (restart) and reset

Use iTunes to restore your iOS device to factory settings

HI, same thing happened to me. Do you have any luck already?

Hi, I have the same problem with my iPhone 5s. Have you tried to reset your phone already? any luck so far? Thanks!
