Because the sensor is provisioned with a unique key to encrypt the link to the CPU. It is designed to be in this way in order to be secure. You just destroyed Touch ID on this phone, forever.

Yes, they are selling things that will never work properly.

Tom is right. Touch id sensor flexes are just as useful as a single pane of iPad mini glass---that has no digitizer fused to it. Offered for sale on eBay every day, and it even comes with a tool kit!

Farkhan--you need to submit a separate question. This question indicates that the original poster did try to replace the touch ID sensor in the phone. It sounds like you have a software, not a hardware problem. A hard reset is likely to solve your problem.

I try to hard reset and restore again but still cant work :-(

You should go to Apple store if you've never opened your phone.
