Get Prepared to Root Galaxy S3:
The method given here is very easy and familiar and takes only a few minutes to perform, but you need to make a few preparations followed by a few clicks.
- Put your device in charging mode to get at least 70% of battery level.
- Back up your contacts, messages, apps, and any important data saved on your device. Backup your contacts, call-logs, messages, APNs, bookmarks, calendar, apps & games using these nice free apps.
- Open Settings on your SGS3 and turn on USB Debugging: Settings> Developer Options>
- Download Odin3-v3.04 and extract the zip on your computer’s desktop.
- If Odin3-V3.04 doesn’t work for you, download Odin3_v1.85.zip and use it the same way.
- Download CF-Root-SGS3-v6.4.zip file and extract it too at the desktop. In the extracted folder you will find a .tar file.
- If you wish to install CWM Touch Recovery, download the following file and install it using Odin using Odin after installing the CF-Root package.
- Alternatively, you can also install the TWRP Recovery on your Galaxy S3. Just install the latest .tar file from the following link and install it using Odin.
- Download and install Samsung USB drivers on your computer. Do not forget to restart your PC after installing the USB drivers.
Steps to Root SGS3 on Android 4.1.2:
- Turn off your phone. Boot it into Download Mode: long press Volume Down + Home (center) keys simultaneously, and then press the Power button for a few seconds. The Download Mode screen will look something like this:
- It will prompt you to press volume up or down key. Press the Volume Up key.
- Now go to the Odin-v3.04 folder and run the Odin.exe file by a double click.
- When you can see the Odin window, connect your S3 to the computer via a USB cable.
- The ID:COM port at the Odin should turn green showing that it has detected the device.
- Do not play with any of the check boxes on the Odin and directly click on the PDA button. Browse to the “CF-Root-SGS3-v6.4.tar” file and select it.
- Now click on the “Start” button and let the Odin flash the insecure kernel, CWM Recovery, and the Super User app to you device.
- When the installation is finished, the ID:COM port will turn green and show a PASS! message. It indicates that your device has been rooted successfully.
- Your Galaxy S3 should now reboot automatically. You can remove the USB cable now.
- If you need to enter the ClockworkMod Recovery any time later, just press and hold the Volume Up + Home button and then the Power button.

Hello there Mr. Shukla, I was wondering if you have a 1 Click Root option for the Galaxy S3 (SGH-1747) running 4.1.2?
Hi Ray, see here: https://www.droidviews.com/root-your-att-galaxy-s3-sgh-i747-with-one-click-on-windows-mac-and-linux/
Plz can u tell me how to unroot my S3. I successfully rooted with the above method.
Install official firmware back.
U mean to say download the stock rom from samsungupdates.com and flash it using odin ??
Yes, you got it right.
thanks sir.. 🙂
actually was facing bit of heating problem on S3 so thought of unrooting n getting it checked from the service centre..
To fix heating, try some other Kernel. Search for Siyah Kernel for S3 and install it via recovery. Method is given here- http://droidviews.com/2013/things-to-do-before-and-after-installing-a-rom-troubleshooter/
Thanks for ur suggestions Sir..
I’ve flashed stock rom n cleared the counter.. heating has lessened.. if any problems arise now, i’ve still got the warranty..
Ur Tutorials are AWESOME.. thanks again..:-)
Can u suggest something for heating?? I even did factory reset but as soon as i turn on the screen within minutes i fell the heat.. i dont even run any high cpu consuming apps..
Try some custom ROM.
Thanks for the guide. I went through all the steps, but it came up as a fail!
Do you know why this might be?
Possible reasons: USB Debugging not enabled, wrong phone model (make sure you have (GT-I9300)
If these reasons do not apply, try again with different versions of Odin:
Perfect! PASS! Thank you.
It worked with the second version of Odin.
Will this method work on sprint galaxy s3 SPH-L710?
It will now work but here is a separate tutorial: http://droidviews.com/2013/root-install-cwm-recovery-on-sprintt-mobileattrogers-galaxy-s3/
in the article you said that CWM will installed after the process …. how could i install a TWRP recovery file to an unrooted phone
Sorry, I did not understand what you actually trying to say.
Will this factory reset my phone?
No, it will not.
It keeps getting fail for me what should i do ?
try with this Odin: http://d-h.st/M14
hii i can’t download the cf-root- form this website..will u plz tell me the alternative one plz??/
It is already there. Click on the “Mirror Link” in the brackets you will find alternative link.
The CF-Root-….file cannot be downloaded..it starts the download but after few seconds it will stop with a message “cannot read from source file” something like that. Anybody experience the same as I do?
Don’t worry, I am adding a mirror.
The method is OK but it does not work with the proposed Odin v3.04! When I used my old Odin3 v1.85 it went as supposed! Just as ICS and the first JB.
Well, I have rooted my own S3 with the same procedure and then wrote this post. May be it did not work for you, but I can’t ignore what I went through myself either.
It might have had to do with a faulty USB cable.
