I want to root my Samsung galaxy s5, but I'm wondering if I need a usb data transfer cable. Also, how do I root it? I know I need a computer, which I have. My model number is SM-G900F, Baseband version G900FXXU1CPFG, android version 6.0.1
But, as mustang asked, why do you want to root it? You aren't running any apps that require root access now, so unless there's an app that you want to run that requires root access, rooting the phone won't change anything. (Rooting doesn't change the way any app works, unless the app requires root access, in which case it won't work without root.)
