Chosen Solution
I replaced my display with an iFixit kit, keeping my original home button.
Once completed, the home button would not respond and I got a no touch id error.
I then re-installed the old screen with the same home button and everything worked.
Could this be a faulty replacement part?
You’ll need to transfer this part from the old screen to the replacement screen. Sounds like the interconnect ribbon cable for home button is no good: iPhone 6 LCD and Digitizer Replacement Refer to step 38 for the part in question.
