I know i’m now doomed and the only way to get it scanning again is by apple… but can you explain on why it did this…? I purchased the full assembly from ifixit, I even transferred the original home button to the new screen… how can this happen? and how can this be prevented?
Is this a good question?

One of two things happened:
Too much force was placed on the home button flex when it was being removed from the old display (this thing is pretty fragile) and caused the issue. If that happened, it is likely that the home button would not function at all.
The other possibility is that the replacement display has a defective home button flex.
one way to test this (assuming you still have a working LCD on the old, broken display) is to put the old display back on the phone with the home button and see if you get TouchID back. If your LCD is broken on the old display, you can probably find a nearby repair shop that would be willing to troubleshoot that for you.
If you find that you get TouchID back on a different display, then it is a parts issue, and your display should be returned for a replacement.
Best practice to avoid damage to the home button during repair is to never put undue pressure on the flex. pop the connector, gently push the home button up from the front of the display to separate the gasket from the display assembly, and very, VERY carefully use a pry tool to cut the adhesive under the chip to the right of the connector.
Was this answer helpful?
Well, the home button still functions as a home button but not a scanner... but could it really be a malfunctioning lcd...? It’s from ifixit
It absolutely could be the display assembly.
Best way to troubleshoot that is to connect it to a known working display.
Hate to say it, but it's been a long time since I bought a part from iFixit, but there was a reason I stopped.
I love iFixit, but have had problems with a lot of their phone parts in the past.
