ExynosAbuse is an android application that uses an exploit to gain root privileges and install SuperSU (v0.99) on your Samsung Galaxy S3 – Exynos4 chip based device.
It doesn’t require anything else, and it will grant the user full root privileges without asking and without using any special permissions.
Even though, this is not something you should take lightly (as the hack could be used by third-party apps with malicious purposes), it is the fastest, simplest way to date, to get root access on a Samsung Exynos4 type device running factory stock roms. (Finally a simple method of using Titanium Backup without flashing custom images, bootloaders, unlocking device, etc.)
The current version of the app is 1.20 and starting with version1.10, it has the options to disable the exploit (disclaimer: this may break your camera), re-enable the exploit (if you need the camera) and to disable the exploit at boot (before any Android app runs). These options do require root (SuperSU or Superuser) to be installed as well. While this will help protect you, these are workarounds, not actual fixes.
All you need to do is download the app from the links provided below (or the original forum threads), install it (make sure you have enabled “installing from unknown sources”), and click the “Root device” button.
Samsung has been informed of this vulnerability, and it is likely that a fix will be available in the near future, but until then, if you were looking for a 1 click ROOT your Galaxy S3 procedure, this is it.
The method has been tested and works on the following devices (check the forum thread below, as it will be updated with new devices):
