Rooting Samsung Grand Duos without Windows 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:


Navigate to towelroot.com on the mobile device.
Tap the big red lambda (λ) to download the APK file.
Find the APK file, either in the notifications or the Download folder, and tap it to install the app.
Open the app and tap the make it ra1n button.


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.
