Chosen Solution
I just installed a new lightning connector and the install went very smoothly. Now I have no issues with charging the phone but now the touch sensor doesn’t work. It pops up when I turn the phone on and states “Touch Id is unavailable on this phone”. Anyone have this happen before?
There’s a good chance you accidentally ripped the home button flex by accident, which can lead to this issue. Other causes would be damaging the home button itself, or not having it seated correctly. I’d take a magnifying glass and look over the flex cable to see if you can spot any micro-tears. Good luck!

You realize that t repair that cable you have to be a extremely experienced micrsoldering technician with great skills. There are at least 10 wires in the cable and they are smaller than a human hair. You also will need quite a bit of expensive equipment.
