The other day I rooted my gnex via wugs toolkit. This morning I tried to install the codename android ROM via ROM Manger. It appeared to be successful, but on reboot it ran the standard ICS bootscreen for about 20 minutes before I pulled the battery. After a little bit of freaking out and reading threads, I flashed back to stock (thanks again wug) and have my phone functioning again. I intend to root it again, and am still interested in different ROMs etc... but before I try again, I'd like to have an idea about what I did wrong. Thoughts?
