Well, it is at least odd as the site you are referring to has no support by other members so it is only for those familiar with the material! Hence the OP came straight back to ask!
BTW, on the first and second page of the HTC One Development Section I was able to find every aspect regarding unlocking, rooting, flashing ROMs, and going back to stock. It took like 60 seconds!
The site might be nice but lacks the traffic you find here...
