Home button won't work

I installed a new screen assembly following all the instructions from IFIXIT but after reconnecting everything my phone gives me an error on startup that says TOUCHID does not work, and my home button won't function at all. Screen works fine.

Please help.

Most likely a faulty screen as the home button extension cable comes together with the screen.

I assume you have already checked the home button cable and the connectors for them logic board screen connector side and screen side.

I checked the cable from the home button to the lcd and it connects just fine, appears to connect correctly just like the other connections internally. I reinstalled my old LCD assembly and home button and now it's giving me the same issue; no home button functionality at all. LCD screen works fine.

Did I need to disable touch ID or something before I uninstalled the LCD assembly home button? Thinking my home button and cable are the issue now. And from what i've read they can't be replaced. Any ideas?


Have you made sure battery was unplugged before changing screens?

Sounds like home button got damaged.
