So I'm trying to flash adb my android (mostly following this guide), and I'm getting stuck at the unlock device step. I can successfully unlock, but once I reboot my device it reverts to being locked. Apparently I'm unable to continue to the next step without having my device rebooted after it's unlocked.
(I have tried using the volume keys to reboot bootloader, and terminal to reboot it. Neither work.)
I'm using a mac, Samsung Galaxy Nexus, and my initial problem was that my phone was (and still is) stuck in a reboot cycle.
