I never updated my iPhone 6+ to iOS 8.0.1
AT&T is my cellular service in Florida
OTA updated to iOS 8.0.2
Result: Touch ID no longer works and "Searching..." for past hour even after multiple reboots and resetted network settings
Have you tried to restart your phone or reset your network settings?
Also, you can go to general > about and see if there is a carrier update if you are on wifi. It will automatically prompt you if here is.
17MBPC2D, did you ever hook up your 6+ to iTunes and download the updated carrier data? Just curious if you saw that notification and have the latest data.
Not entirely sure if it matters, but just a thought...
I'm on AT&T and not having any issues with 8.0.2...
