I'm just passing along the info!
[INFO]- This will teach you how to successfully gain root access on your Galaxy S3 smartphone using CF-Root by Chainfire from XDA. Use all the instructions that I have listed in this post and you will manage to root your device.
This tutorial should be used by advanced Android users and you should apply it on your device in case you wish to get access to all other Galaxy S3 functions. Applying this root will allow you to install new Custom Jelly Bean ROMs that will improve the overall performance of your device.
Note that before rooting your device, you will first need to read the pre-requisites guide and learn what you have to do so that the root process will complete successfully. Remember that you might be forced to wipe the data after applying the root, as the device might be able to boot properly. More about this can be found in the prep guide.
CF-Root tool was created by Chainfire and it is one of the most popular rooting solutions for Galaxy S3 owners. You should be able to flash all files in under five minutes without the need of losing any data. The only thing that you need to remember is that in case the phone doesn?t power ON after the root, you will need to boot into a custom recovery mode and wipe data and factory reset the device. Hopefully, you won?t need to do all that and the root will apply successfully.
Now that you read all of the above, I think that you should move to the pre-requisites and guidelines part of this post and, learn how to properly configure your device so that you?ll manage to root the Galaxy S3 I9300 at your first attempt.

Here?s what you need to know:
TUTORIAL
How to root Galaxy S3 I9300 on Android 4.1.1 XXDLIB Firmware with CF-Root:
1) Download CF-Root XXDLIB rooting zip file HERE. Extract its contents into a single folder on your desktop. You should get a single ?CF-Root-SGS3-v6.4.tar? file. Do not extract any furtherthan that.
2) Download Odin 1.85 from HERE. Unzip it into the same folder as the XXDLIB rooted firmware.
3) Now, power off your smartphone as you will need to boot it into Download mode.
4) Enter Download Mode by pressing at the same time ?volume down? + ?home? + ?power? buttons. Release the buttons when the screen lights up. The phone will load a welcoming screen and you will be told press ?volume up? in order to enter Download Mode. ODIN should say ?ADDED? and this means that the phone was recognized by the PC and you?re good to go. If ODIN doesn?t display the added message, then you need to reinstall the Samsung USB drivers as otherwise you cannot root your phone.
5) Launch ODIN executable on your computer and connect your SGS3 to your computer using the USB cable.
6) In ODIN click the ?PDA? tab button and browse your computer for the ?CF-Root-SGS3-v6.4.tar? file. Load it into ODIN and move to the next step.
7) Do not change any default Odin settings and then click on START. Now the rooting process will be launched and you should wait at least 3 minutes for it to complete.
8) When the root is completed, your Galaxy S3 will restart and ODIN should say ?PASS?. This means that the root was applied and your phone can be disconnected from your PC.
9) After the SGS3 boots successfully, you should go to Play Store and download the ?Root Checker? app on your device and run it to see if the root was applied. Alternatively, you can search your App drawer for the SuperSU / SuperUser application, as that will mean that the guide was successful.
10) Now that the root has been applied, you can begin the search for new Jelly Bean root-based applications or you can even install a brand new custom Android 4.1.1 JB ROM.
ENJOY
[NOTE]NOTE: In case ODIN doesn?t display the ?PASS? alert, then the root wasn?t installed and you have to close ODIN, disconnect the phone from PC, power off the phone, remove its battery, re-insert it back in its place and then re-run ODIN and connect the PC with your SGS3. Repeat the entire tutorial again and this time make sure that ODIN completes the root.[/NOTE]
[NOTE]NOTE 2: If ODIN displays the ?PASS? message but, the phone is unable to go past the boot animation or it gets into a boot loop, then it means that you will have to wipe data and factory reset the device. Remember that this step will delete all installed apps, SMS and other data that is stored on your device, which means that you cannot retrieve it.
Here?s how to enter custom recovery mode and force your phone to boot normally after root:
- Power off the SGS3 and remove its battery. Re-insert the battery after 4 seconds.
- Press the following buttons at the same time until the screen powers ON : volume up, home and power.
- The custom Recovery mode will load now and you have to select ?wipe data/ factory reset? option.
- Confirm this process.
- Return to the main recovery screen and then select ?reboot system now?.
- Galaxy S3 should now boot normally and it should be rooted.
