I have a Nexus7 Tablet (2012) with Android 4.4.2. I'd like to root it, so that I can use some Apps, that need superuser rights.
I just found tutorial that explain how to root this device using a Custom ROM. Is it possible to root without installing a Custom ROM? Why is it not possible to just install "su" on the Tablet as I did with my Phone?
su
, you need root.
