Hi, I made this How to Root guide for the Sprint GS3. However after changing a few files it also works with the AT&T Galaxy S3. It has been verified to work on the AT&T version. I wish you Great success and HAPPY Flashing!

Rooting the AT&T Galaxy S3 couldn't be easier. With just a half hour and a few steps, you could be rooted and on your way. All files required are included in this guide.
[NOTE]Your Samsung Drivers MUST be installed correctly on your computer prior to continuing.
Wait until the software installs completely before plugging your device into the computer. When you have completed driver installation, plug in your device. The computer should now tell you it is installing drivers, click on the details and wait until there is a green check by all the drivers. Unplugging your device before it's complete will cause you problems...
[NOTE]
Attention Windows 8 Users: The drivers below are updated to work on Windows 8. If you have upgraded to Windows 8, installed these drivers and they still won't work, you will have to install the drivers in compatibility mode. [/NOTE]
GS3 Drivers Download and install on your computer.[/NOTE]
Preparing your computer
You will need to download the following files to your desktop or notebook computer. Just click on the file names and that should download the file required. I would suggest you make a folder on your desktop and name it something like Root GS3.
Odin3.07.zip recovery-clockwork- Touch-6.0.2.3
After downloading the above files to your computer:
1. double click on the "Odin 3.07 zip". Copy the "Odin307"
folder (That is inside the zip file) into your "Root GS3" folder.
2. Move "recovery.tar" into the Root GS3 Folder
Preparing your Phone
Download the following file and place it on the root of either the internal or external SdCard. I prefer the external as that is where cwm defaults to.
Team Epic Root From Recovery
[NOTE]Phone should be off prior to attempting to go into Download or Recovery Modes.[/NOTE]
[NOTE]
Download mode is achieved by pressing and
holding "volume
down, power button and the (physical) home button simultaneously. You will continue to hold all 3 buttons until you see a warning. Then press the volume up button and you will be in download mode.
[/NOTE]
[TIP] Recovery mode is a bit trickier. If you're a second too early or too late, your phone will skip going into recovery and boot normally. If this happens you will have to repeat the Odin process in it's entirety. So unless you are familiar with this, I would give it a few practice runs before starting Odin [/TIP]
[NOTE]
Recovery mode is achieved pressing and
holding "volume
UP, power button and the (physical) home button simultaneously. Watching the screen closely, release all 3 buttons as soon as you see the word Samsung. If timed correctly it will boot into recovery in about 10-20 seconds (after releasing).
Remember if you are too early or late the phone will boot normally and skip recovery.
[/NOTE]
[INFO]Samsung added 2 files that made rooting just different enough to make us change the way we do things.
/system/ect/install-recovery.sh & /system/recovery-from-boot.p
What these 2 files did, caused the phone to look for stock recovery every time the phone was booted. If stock recovery was not found it was re-installed.
The TeamEpic-Root-from-Recovery -v5. file was created by TeamEpic to not only install superuser and busybox, it also removes those 2 files that Samsung gave us. Because of the way those files wipe the custom recovery,
The Root From Recovery file must be installed before the 1st boot up. This is why we now have to turn off auto reboot in Odin and pull the battery from the phone. [/INFO]
Using Odin
1. Open the "Odin307" folder and right click on "Odin3 v3.07.exe" and choose run as administrator. Odin will open.
2. Remove battery cover from phone for future access
3. Place your phone into download mode.
See above Download note.
4. Plug your usb cord to your phone and computer and wait until you see any number and com in the com block
5. Click on the PDA button and browse to "recovery.tar.md5" in your Root GS3 Folder.
6. Verify that both Auto Reboot and F. Rest Time are
UNCHECKED.
When all this is done Odin should look like this:
7. If everything is like the picture above click on the start button. It should move very quickly as recovery is a small file. It is normally completed within 10-20 seconds (depending on the speed of your computer and usb port).
This is what Odin should look like when complete.
[NOTE]Sometimes Odin will not show "PASS!" in the top left corner. So observe the message window as well. If it shows "All Threads completed (Succeed 1 / Failed 0) you should be fine.[/NOTE]
8. Remove Battery and disconnect phone from computer.
Flashing Root in Recovery
1. Install battery
2. Place your phone into Recovery Mode. See above Recovery note.
[INFO]The Recovery that you installed is a touch screen recovery. You will not need use the buttons to navigate through the recovery menus.[/INFO]
3. Once in recovery tap on "install zip from sdcard".
4. Now you will tap either "choose zip from sdcard" or "choose zip from internal sdcard"
5. Scroll by swyping up and down on screen. Tap on "TeamEpic-Root-from-Recovery-v5.zip.
6. Tap on "- Yes - Install TeamEpic-Root-from-Recovery -v5.
Once complete, tap the "go back" button once and then the "reboot system now" button.
You Are now fully rooted with custom recovery installed.
