must have damaged the touch-ID.
bump. Same problem here. Tried replacing the metal shield with the cable connecting touch ID to the logic board with several original flex cables, still no luck. I take it my colleague must have damaged the touch-ID. Is there any workaround?
UPDATE: I swapped the home-button for a button laying around in the shop, possibly the original one and it worked.
Anyone know if the same goes for iphone 5s where you swap home button? Got a customer with working touch ID but defective button but don't want to have to put the original back in every time she updates.
