Touch ID not working iPhone 6


There was water damage on the home button itself and would boot loop

Cleaned corrosion, resoldered some corroded pins and now phone boots and home button works but Touch ID fails and can't be set up.

Is there a schematic for the home button itself?

I've done that. Still same issue. Any component on the home button that would cause id not to work? No corrosion on logic board side
