So...I first started rooting and custom rom'ing back in the Samsung Fascinate days, flash forward...I sold my s3 because I was in love with what I heard about the HTC One!! Found one on Craigslist in great condition. Dude I had bought it from said it had been rooted and I thought GREAT, saves me the trouble!! Well, I'm confused. I am running a modified 4.3, locked with s-on, and rooted. I am able to boot into TWRP. I cannot figure out the tech of the HTC One and need to know 2 things...1. How is this phone rooted with locked bootloader/s-on? 2. Where can I go from here... Can I flash other rom's through TWRP even though bootloader is locked and s-on? I have read everything I can on xda and still can't make sense of this...
