Why won't my HTC One M7 root?

[AC Question]

I unlocked the phone, installed TWRP and used it to install SuperSU. And nothing changed. I still don't have root. What else should I do? Please help!

This is a short answer:
Ensure you are using the latest version of TWRP.
Update the su Binary if it asks you to.
Use CWM instead.
