Default So can one root GPE or...?

Hey guys,

It's been a while since I've been on XDA. Last week I decided to get me an HTC One and so one hour later curiosity has led me to rooting this thing. Only problem is... nothing works. Initially I tried using the "simple" oem unlock. Which should have worked but my terminal gave me a series of error messages informing me that it couldn't access the splash image. So I tried HTC Dev and that doesn't work either. I've spent hours combing every thread on the internet regarding this, and although I've been educated on my initial errors, I've been led in circles.

I am Locked, S-On, 1.54 Hboot, and 4.4.2 Kit Kat. Can I ever root this thing? I'm so surprised that out of all the iterations of the One, the GPE is the one that is impossible to root. Or maybe I'm not paying close enough attention? I've looked at all the S-Off techniques and they don't seem compatible with the GPE? I have no clue. Any help would be great!
