Hey guys. I'm using a galaxy nexus and it's not rooted. I got the 4.2 update and I don't like it one bit. The only thing good about it is the photosphere. My battery life has reduced by almost half and the brightness bug (among others) is annoying. So I wanted to root my phone and install a custom (4.1) rom. I have always been wanting to do this for a while and now I have a reason to. Lol. Can you guys guide me about the whole thing? Is it possible and safe to install a 4.1 rom on my phone which is currently running on 4.2? What happens to the stock rom once I install a custom rom? Are there chances of my phone bricking? What am I supposed to do if my phone bricks?
