If you go to the xda Rezound development forums there is one of the top threads that is called all in one toolkit. Watch the video. It's easy as pie
edit: well unlocking the phone and installing cwm is easy.. used another one click perm root tool to root the phone.. getting a rom to work decently is a whole notha ball game..
maybe its the roms i been using or maybe im doing it wrong but I have tried 2 roms so far and they both have made my phone unusable. One of them kept giving me force close errors non-stop, and the second one keeps rebooting whenever you do ANYTHING.
