Installing a custom recovery on the Samsung Galaxy Mega 5.8 is the second step after rooting it. While root allows you to enjoy root-requiring apps, a custom recovery like CWM makes it possible for you to enjoy custom ROMs on your phone.

Custom ROMs cannot be installed like an app on your phone. They must be flashed either through Odin or a custom recovery and only then they can be functional. Using the latter method to flash a custom ROM is what we’d recommend you to do.
