How To Root AT&T Samsung Galaxy S3

AT&T Galaxy S III


The Galaxy S III is the first Android phone to launch as it is on all the four major U.S carrier networks simultaneously. The AT&T variant of the Galaxy S III is no different than the International version except for a change in SoC and 2GB of RAM, instead of 1. AT&T is also the only operator in the U.S that managed to pick-up an exclusive red color variant of the Galaxy S III that is expected sometime this fall.

Rooting Guide

Rooting a Samsung phone is pretty easy, thanks to ODIN and the unlocked bootloaders of their devices. The U.S variants of the Galaxy S3 are no exception to this. A simple toolkit from XDA moderator, mskip, makes rooting the U.S variants of the Galaxy S3 a breeze.

While using the Toolkit is pretty self-explanatory, I have still written a guide for newbies. Below is the guide to root the AT&T variant of the Galaxy S III. The rooting guide of Sprint, T-Mobile and Verizon variants can be found here, here and here, respectively.

Step 1: Download the AT&T Galaxy S3 Toolkit from here, and install it on your PC.

Step 2: Start the Toolkit, and select your phone model and build from the list. AT&T S3 owners need to select the 1st option. Do make sure that you are running the same build as supported by the Toolkit. Even if the toolkit does not support the current Android build your phone is running, simply select your phone from the list and proceed to the next step.

Step 3: Install the Drivers on your PC by selecting the 1st option, once again. Make sure the drivers are installed properly, without any issues.

Step 4: Once the drivers are installed, select the 2nd option in the Toolkit i.e ‘Rooting Options’.

Step 5: If your phone is running a build supported by the Toolkit, select the 3rd option i.e. ‘ALLINONE’. If it is not supported, select the 4th option, ‘Flash CWM + Install Root Via Recovery’.

The steps after this will be properly explained in the Toolkit itself. I don’t think they need any kind of explanation here.

To enter ‘Download mode’ on your Galaxy S3, switch off the device, re-insert the battery and then press the Volume Down+Home+Power button simultaneously. Skip the custom OS warning by pressing the Volume Up button.
