How to avoid error 53 when replacing the motherboard on iPhone 6

so in simple words :

-iPhone X is like new everything works but has Logic board is bad.

- iPhone Y has a bad LCD and bad housing but Logic board works .

As per the relationship between Error 53, home button and logic board, some say that every home button is paired to it's original logic board, others say that it's the hardware/flex ribbon on the back plate that is paired with the logic board and not the actual button itself .

so to avoid E53 when replacing the logic board on phone X, do I have to :

1-also remove the back plate with the Flex ribbon and home button from phone Y to go with their respective logic board on phone X ?

2-just replace the home button alone ?

3-replace the back plate with the flex ribbon on the working LCD but keep the home button ?

I hope that option 3 applies as the two phone are of different colors and would not want a black phone with white home button, but if it's not, so let it be !

Any suggestions please ?
