I am wanting to download CWM recovery. I know the file needs to be specific for Samsung Galaxy S4 i337 with AT&T. I am running Android 4.2, . Does the CWM (.tar) file also need to be specific to the version of Android that is being run? I have ROM Toolbox Pro with a great custom ROM installer, but I am not sure i can use it before having a Recovery program like CWM or TRWP downloaded.
