Taking no credit to this one. Did root my friends phone using this method & its a lifesaver in fact being that i didnt have to roll back the update on the phone or do something else... So heres for those who have the slightest clue & are wondering how to root their phones with this HBOOT. Only thing is that this doesnt gain s-off but just unlocks the bootloader rest of the work is done from a command line promt. Read up & have fun. Btw it is possible to flash other forms of recoveries such as amon_ra or twrp being your preference...
You CAN Root the new Hboot, and you don't need s-off. (strictly for those who don't know and need help)
