so I recently tried to root my oneplus 2 to be able to flash cm13 onto it. I followed the guide oneplus provided on youtube (https://www.youtube.com/watch?v=KZaajUEybNM) exactly and got the same results for everything except that my phone does not boot. The only differences between my phone and their guide were that I had a newer operating system (Oxygen OS 3.0.1) and I flashed the latest version for everything, also I went for the Stable version of Super SU instead of the beta. I understand that he said it would take a little time to boot, but I am assuming he doesn't mean 5+ hours.
I am still able to boot into recovery (TWRP) and fastboot but not the OS. I tried wiping the phone and installing Super SU again, but no luck. I am stuck here and don't know what to do next. Any help would be amazing and extremely appreciated.
