Chosen Solution
So, I have replaced shattered screen, but it seems like I have teared the socket off the cable while moving the home button on accident. The button surprisingly works, but there is now a notification about not working Touch ID. Considering it working more or less before and I kept the button for that reason I’m want to replace the cable, but the only replacements I could find which I can buy in my country are for 6 Plus and as I am new to repairing phones I’m not sure the difference between two when it comes to stuff like these parts. Do you think it’s possible to use 6 Plus home button cable in 6?
The iPhone 6 and 6+ use the same touch ID enabled home button, so you won’t have any issues there. However, Touch ID functionally is tied directly into the motherboard, replacing it entirely might limit access to updates (security or otherwise) while also not resolving the issue of touch ID not working. The only solution (to my knowledge) would be to swap the cable and leave the original home button as you mentioned, however it would be quite difficult to do and there’s no guarantee it would work.
