As we all know, Android 4.3 brought with  it some extra security features which caused some small issues with root. These have been solved by the likes of Chainfire and other developers, meaning we have root once more. This is their work, I've just botched it together to work on the Android x86 4.3 system, which works slightly differently

You will need:
A device with Android x86 4.3 on it
Optionals:
Another Linux based OS - this can be an OS on another partition on the device or a live disk/USB
Root permissions in that second OS and access to the terminal
Knowledge of which partition Android x86 is installed onto and which is its root folder (if you didn't mess with that, it tells you in the script)

Instructions:
On Android x86:

Download the attached zip and extract it using a file manager
Press Alt+F1 and use "cd" to change directory to where you extracted the zip
You should go as far in as the "README" and "install.sh" files
Run:

Code:
sh install.sh

Follow the instructions on-screen. It tells you the rest.



Changelog:


v2:
Included version for Android x86 boot, through the Alt+F1 terminal
Made it a bit simpler
