http://forum.xda-developers.com – Hello everyone, i want to root my Galaxy Note 2 and i don't want to change my current (default) android firmware (4.1.1 i believe), is it possible to root the device without installing the new firmware. I downloaded the odin and read the instruction which included the installation of firmware. And is it compulsory to backup the data (i mean will the data be removed from the device when rooting?) do i have to get separate sd card as well for rooting or i can have it later when i want. I just want the root privileges so i can install apps to external sd card and use chainfire3d for tegra a (HowTos)
