  1. The first step involved is the Downloading of the root CWM Super user .zip package from HERE. Once you download it, please save it on your computer.
  2. Then just go ahead and connect your phone to your computer and once you have done this, also move the ‘cwm superuser’ zip file on your SGS3 internal sdcard. Monitor, if the transfer is complete, and when it completes, do disconnect the device from your PC.
  3. Now you have to Power off the phone and then boot it into CWM Recovery. This can very easily be achieved by simply pressing and holding ‘volume up’ + ‘home’ + ‘power’ buttons. You will, afterwards, simply Wait until the CWM Recovery mode screen shows up.
  4. Also -while in recovery mode, you have to select ‘install zip from sdcard’ and from the next menu select ‘choose zip from sdcard’ or ‘choose zip from internal sdcard’. Once you detect and get your eyes on the CWM SuperUser zip file, you shall have to select it.

  6. Now it gets a little bit easier – and when the installation of CWM SuperUser has been finished,you will have to immediately go back to the main recovery screen.
  7. Once you went back there, you also have to Select ‘reboot system now’ and then wait for your Galaxy S3 AT&T to load the home screen.

    I have a question on your rooting instructions for CWM method… I was following the instructions step for step, but, there’s a problem. Your first step says you have to download the root .zip file, and transfer it to you GS3 (successful). Then, immediately after that, you need to boot into recovery mode using CWM.

    The problem in this, is that you have to be rooted in order to use CWM… I downloaded CWM and tried to set it up, but it says I must have Superuser… when I reboot into recovery mode, it’s just the standard recovery mode, with no install options…. So, either these steps are wrong, or there was a step totally missed.

    So, how can I root my phone using CWM, if you have to be rooted in order to use CWM??
