Looked into myself to get more functionality like real back-up etc. but backed off because the tool everybody uses and you can find you tube videos about how to do is I think called Kingo root which you download to PC. Software uses exploits on pc to get task done but then I'm thinking definitely no support if things don't work. After downloading some issues on PC so use a POS PC to do this I suggest. I can't state that I did it myself and worked but definitely watch videos first.
