Hey. I'm sorry to be the bearer of bad news, but with the ever famous locked bootloader that TMobile has grown so fond of, there hasn't been root established. I have the only three devices in the world that are unrootable and the Revvl Plus is one of them. You may want to check in on XDA forums and perform a search though because it is updated daily. Good luck and please, do not attempt to use Kingoroot or Kingroot. You stand a very good chance of bricking your phone that way. Good luck
