I'm trying to bring my Moto back to stock but I'm not sure of which stock ROM is the one I need. I'm on the version bought on Amazon but without the ads on the lockscreen. I've looked at the stock ROMs on the firmware center page and see a few with AMZ in the name. But since it's not the ad supported version, which one do I need to use? Thanks for any help anyone can offer. It's much appreciated. Sorry since I'm new a new poster, I can't post the actual link to the site.
