After that, I started to look into doing it manually. I tried clicking the Root button on the toolkit (with the flash custom recovery option checked), and it hung up on the booting into TWRP part.
The unlock was successful (UNLOCKED shown in bootloader and white unlock icon on Google boot screen), but I'm getting tripped up on the rooting part of the process. I used WugFresh's root toolkit to backup and unlock the phone. I am trying to gain root on my Verizon GNex in order to install Jelly Bean.
