Odin not needed with SS 3.72 and kitkat. If you're on 3.71and kitkat then I assume you'll have to go back to JB and flash with Odin.
Odin is not needed if you are running Safestrap 3.72 and already on a KitKat based ROM.
If you are on a Jelly Bean based ROM you will need to upgrade from JB to KK using Odin. Here is the link to doing so in case anyone needs it....
