Hi i am trying to install CWM Recovery for my galaxy w but can someone tell me the difference between installing CWM like this (http://xdaforums.com/showthread.php?t=1446593) and installing it by downloading ROM Manager from the market (https://play.google.com/store/apps/details?id=com.koushikdutta.rommanager&hl=en) and use the option Flash CWM Recovery as seen in the first app screenshot.
