Where do I download HBOOT 2.16?

I need HBOOT 2.16 to flash my preferred ROM on a HTC One S. I can't figure out where to download the firmware itself. The only page I've found which even vaguely resembles clear instructions is [this one](https://forum.xda-developers.com/htc-one-s/general/guide-how-to-install-hboot-2-16-time-t2898605) but the [download link](https://mega.co.nz/#!EAJFFDAK!KczIBV2jCY71Vf_AOM1UVDA6Z_4EwGxyqyq05XzjrnQ) for the firmware is broken. The other pages I've seen present a very muddled picture and no links through which to download the actual firmware. I have a rooted device, S-OFF, super CID 11111111, formerly H3G__001 I believe. I'm going round in circles trying to figure this out. How do I upgrade my firmware?
