AT&T Galaxy S3

If you have the AT&T Galaxy S3 SGH-I747 and are willing to root your phone, we have a good news for you. Adam Outler from XDA has come up with an all new way of rooting the AT&T variant of the Galaxy S3. If you do not know, Adam is the same guy who first devised a way to unlock bootloader and root the Verizon Galaxy Note 2.

The very idea of a universal cross-platform tool for rooting Samsung Galaxy devices is very exciting in itself. And though the Casual root tool is currently restricted to the AT&T variant of the Galaxy S3, we have no doubt that Adam will be directing the development to all Samsung Galaxy phones. The Casual root tool has been successfully tested on Windows and Linux while the developer is still trying to overcome the hurdles with Mac.

The Casual root tool is build upon Java codes found and supported with all Operating systems and thus it breaks away from OS compatibility issues and makes rooting a child’s play. Yes, it demand just a single mouse click to give root privileges on your AT&T Galaxy S3 I747.

How to Use:

  • Please note that the root tool requires the presence of latest version Java on your computer. If you do not have it, download it now. In case you have it, make sure to check if it is the latest version. Click here to run the Java Test.verified-java
  • Next, you must have a compatible USB Driver installed on your computer. Download USB Drivers here.
  • Download the latest Root AT&T GS3 – CASUAL Revision
  • Turn on USB Debugging mode on your Galaxy S3 from Settings> Development.
  • You need not boot your device in Download mode.
  • Now double click the CASUAL-Revision308b.jar file to launch it. It will take a few seconds to launch.
  • When it is opened, connect your phone to computer using a USB cable.
  • When the Link Status shows “Device Connected”, just click on the “Do it” button.
  • Wait for a few seconds and your Galaxy S3 will be rooted.

    Try a different browser and turn off your antivirus program temporarily.

  • jfinney75

    4.4.2. I also tried to root with the towelroot method, but the apk file wouldn’t download for me

  • http://www.droidviews.com/ Rakesh

    Just disconnect the phone and long press the power button till the device boots, or pull out the battery, put it back and turn on your phone.

    What Android version your S3 has?

  • jfinney75

    My phone is connected to my computer via USB cable and is in download mode. However, it shows up as disconnected under link status. What do I do now? My phone is still in download mode and I don’t want to mess anything up. It says, “Do not turn off your target!!” Please help

  • http://unlockedanswers.wix.com/papercrafts Mine-Crater

    Everything seemed to work perfectly, except SuperSU seems to crash instantly whenever i try to open it, is this normal? Sorry im a noob

  • http://www.droidviews.com/ Rakesh

    Yes, it works. To solve the KNOX blocking SU issue, read this: http://www.droidviews.com/disable-knox-security-service-on-samsung-galaxy-devices/

  • Rogers

    Does this work with Galaxy S3 with 4.3? I tried it with Odin but after that, KNOX warning popped up, and SuperSU blocked.

  • KEI

    is 4.12 Jelly Bean, no blue bar was there, everything was frozen
    I can reboot the device and nothing happened
    but I used Odin3.07 and root successfully
    just let u know
    and i like your article a lot! plz fix it!

  • http://droidviews.com/ Rakesh

    Do you see a blue progress bar on the screen? If no, you can disconnect the device and reboot it.

    I guess your phone has Android 4.3. If yes, try Saferoot: http://www.droidviews.com/root-verizon-galaxy-s3-android-4-3-vrucml1-firmware/

  • KEI

    Same here, frozen at “Downloading! Do not turn off target”

    Java shows:

    libusbx: error [init_device] device ‘\.USB#VID_046D&PID_C24D#6&2C971334&0&2′ is no longer connected!

    ERROR: Failed to access device. libusb error: -12

    Waiting for ADB device connection. When your OS recognizes the device, we will continue. Don’t touch anything.

    What version of Android your S3 has?

  • http://droidviews.com/ Rakesh

    It takes just a few seconds.

  • CJ Johnson

    no errors show. it just seems to be frozen. using windows 7

  • CJ Johnson

    how long will the screen on my phone stay at the downloading “do not turn off target”?

  • http://droidviews.com/ DroidViews

    Download and install usb drivers (link above), restart computer and try again.

    On device: pull out the battery, wait for a minute and place it back.

  • Ashley Marie Badillo

    hi i just tried to do this and it said it may need to download drivers do i want the program to remove them when it was done and the only option it had was ok but it failed and ran out of retrys so now my phone says downloading do not turn off target and the program says libusb error not supported attempting to continue maxium retries exceeded shutting down cyclic error script complete im not sure what to do

  • http://droidviews.com/ DroidViews

    Pull out the cable and phone’s battery and restart conputer. Reinsert it again after a minute and start over again. Also make sure USB Debugging is turned on from Settings> Developer options on phone.

  • Chris

    Im using MAC Lion and it froze my Samsung Galaxy S3 I747, it said ERROR ERROR Then froze at Downloading to not turn off target!

  • http://droidviews.com/ DroidViews

    Okay. Such things happen.

  • Ariel Hanks

    It did work and I have root. It just froze at the end and i could not “safely remove” phone without killing the script.

  • http://droidviews.com/ DroidViews

    It should work on Win7 64bit. Restart the PC and check if you have missed something, then try again.

  • Ariel Hanks

    The one click script froze at the end. I had to use task manager to stop it. I have windows 7 64bit.

  • http://droidviews.com/ DroidViews

    What do you mean by “force stop application”? To install a custom Recovery, use this app:

  • Ariel Hanks

    no cwm? Had to force stop application when it was done.

    The Casual tool has just been updated. Please, try with the latest version: http://d-h.st/J9a
    Let me know.

  • ray

    didn’t work for me

  • http://droidviews.com/ DroidViews

    Hi, the Casual Root exploit is still in beta state. Mac compatibility bug has always been there from the beginning. However, it’s been reported working on OSX Lion and OSX Mountain Lion.
    Just make sure Java is up-to-date and try again. Some users were able to root the device after 3-4 attempts. Also, do not forget to reboot the computer and device both before each attempt.
    We’ll be updating the post as a workaround is published.
