How to Root Your Samsung Galaxy S3 (GT-I9300) Using CF-Root & ODIN

With the Samsung Galaxy S3 becoming increasingly popular among Android users, there has been several root guides for the device.  Now you can use a piece of software that makes the whole process simpler than ever before.  The CF-Root tool will help you to gain root access to your device, which will give you more control over customization of your Galaxy S3.  This means you will  be able to move even more apps to your SD card, get rid of bloatware and a whole lot more.  This is the fastest way to root your Galaxy, and we are going to take you through step by step to make sure everything goes smoothly.

We want to stress that the CF-Root tool will not work with any device other than model number GT I9300 so should not be attempted if your phone does not match this number.  Your phone will still stay very close to its stock form and this method works perfectly with the standard firmware.

Disclaimer: Gaining root access to your phone will most certainly void any and all warranties.  Furthermore, root access allows you to change settings on your phone that should not be tinkered with by the average user.  It is possibly to brick your device by changing something that you shouldn’t have.  A rooted phone can also be vulnerable to certain malicious scripts and malware so we recommend a robust security suite be installed on your device.  Please also read this guide through before starting the process.  Make sure you understand what is required before starting.

Backup and Other Precautions :

  • Always backup your data just in case something goes wrong.  If you have to do a factory reset all of your data will be lost. Sync your contacts to Gmail or export to the SD card.
  • Fully charge your phones battery or at least to 85%
  • Disable all antivirus software on both your phone and computer for this process.
  • Enable USB debugging on your device.

Remember please that we cannot be held responsible for what happens to your device.  The same holds true to the developers of any software used during the process.  Using the CF-Root tool is done at your own risk.

How to Root your Galaxy S3 I9300 by using CF-Root & ODIN

Below you are going to find two guides.  One is for using your windows PC while the other is for your mobile.

Rooting by CF-Root and ODIN Desktop Edition :-

  1. Download and install the Galaxy S3 GT-I9300 USB drivers if you have not already done so.
  2. Download the CF-Root SGS3 v6.3 zip file and extract all the files.  Only extract the files once.  There will be a .tar file, do not extract that particular file.
  3. Download ODIN v1.85 and extract the files while your phone is disconnected from your computer.
  4. Start the ODIN software, and click the PDA button.
  5. Browse through your files to find the CF-Root-SGS3-v6.0.tar file which was extracted from the zip file in step 2 and select it.
  6. Power down your device so you can boot into download mode.  Do this by holding volume down, home and the power buttons at the same time.  If asked to confirm download mode, do so.
  7. Connect your Galaxy S3 to the computer.
  8. ODIN will display a yellow ID:COM box with a port number if it connects properly.  This may take a few moments.
  9. Please ensure that the Repartition Box is UNCHECKED, and check the Auto Reboot and F. Reset Time options and then click start.  The ODIN software will flash the .tar file to your device and install SuperSU root, ClockWorkMod Recovery and CWM Manager.

After everything is done your phone will reboot and can be disconnected.  If the SuperSU app is installed on your phone, tit worked.

Rooting CF-Root and Mobile ODIN :-

Using this method requires an already rooted device to work.  It will install the latest SuperSU Root app along with ClockWorkMod Recovery and CWM Manager onto your device with root permissions granted.

  1. Download CF-Root-SGS3-v6.3.zip and extract the contents into a folder.  Again, do not extract the .tar file.
  2. Connect your phone to your PC and move the .tar file to the root directory of your SD card.
  3. Install Mobile ODIN onto your Galaxy S3 and then open it.
  4. Choose the Open File option and browse to the .tar file you just transferred.  Pro users disable the ‘EverRoot’ option.
  5. Flash the file and wait for the process to be completed.

If you are flashing over the stock firmware along with the CF-Root tool then you will want to do the firmware first.  The CF-Root will keep the firmwares CSC from installing.

That is all there is to it, you have successfully rooted your Galaxy S3 !
