A few months ago I successfully rooted my Nexus 5 using the first youtube video you see after youtubing "root nexus 5" (sorry, new members cant post links).
unfortunately i had to remove root access for a short period of time. now that i try to reroot the phone using the above method (as well as a few others) It doesnt work.
when I put the phone in fastboot mode it says SECURITY BOOT: enabled and LOCK STATE: unlocked. Im assuming that means the bootloader remains unlocked. when i run the program and my nexus 5 flashes all the magic voodoo rooting screens, the phone boots back up but i still dont have root access.
what in the world can i do here?
