I need to root my Samsung GT-I9082 (also known as Grand Duos) with Android 4.2.2 but I have no Windows computer (I have a Linux one).
Which are the preferred methods?
It seems z4root does nothing (seems just to crash).
Towelroot supports most Samsung devices. Based on a quick Google search, it sounds like it has been confirmed to work on GT-I9082. It's extremely simple:
That's it. You should get a message within about 5-10 seconds telling you that you have root access. You don't need a PC, and you don't even need to power off or reboot. It's so simple it's dangerous, because one doesn't need to have a modicum of technical ability in order to gain root access.
