    I have an SGH-T989 that is currently running AwesomeAudio and 4.4 KitKat. I unfortunately need to re-root my phone, but can’t find a tutorial anywhere on how to do this with a 4.4 KitKat SGH-T989. Please, HELP!

      @disqus_22MdUMrBT7:disqus there is no official KitKat for Note 2, You’re probably running a custom ROM and isn’t that pre rooted? Let us know.
