How To Root Galaxy S III (AT&T, T-Mobile Or Sprint Model) [Tutorial]

The international version of the Galaxy S III was rooted a few weeks ago and now, just days after release, all US variants of the Galaxy S III – for AT&T, Sprint and T-Mobile – have been rooted and we’ve got root guides for all three smartphones ready right after the jump.

DISCLAIMER: I will not be held responsible for any damage incurred to your device as a result of following this guide. Follow at your own risk.

T-Mobile / Sprint
As it turns out the rooting method for T-Mobile and Sprint variants of the Galaxy S III are exactlythe same. Same files, exact same method.

Part 1: Initial Setup

Step 1: Download and install USB drivers for Samsung Galaxy S III [Direct Link].

Step 2: On Galaxy S III, enable USdebugging from Settings > Developer options.

Step 3: Connect your device to your PC via USB cable.

Step 4: Download [Direct Link] and transfer it directly under the parent directory on your device’s internal storage.

Step 5: Disconnect your device from PC and power it off.

Now, onto the second part of the guide:

Part 2: Flashing clockworkmod.tar

Step 6: Download [Direct Link] and extract its contents using a suitable software (we recommend PeaZip).

Step 7: Similarly, download clockworkmod.tar [Direct Link].

Step 8: Boot your Galaxy S III into download mode by pressing and holding Volume Down, Homeand Power buttonsPress Volume Up when the prompt comes up.

Step 9: Once in download mode, run Odin3 v3.04.exe from the .zip file in Step 7.

Step 10: Connect your Galaxy S III with PC once again. Odin should detect your device.

Step 11: Click on PDA and select the clockworkmod.tar file you downloaded in Step 7.

Step 12: Ensure that Auto Reboot and F. Reset Time are selected. Then, click on Start to begin process.

Part 3: Flashing SuperUser

Step 13: Now you must boot into ClockworkMod Recovery Mode. Shut down your device, press and hold Volume Up, Home and Power buttons.

Step 14: Navigate to install zip from sdcard > choose zip from sdcard > [ file you downloaded earlier]

Step 15: After it’s done, choose reboot system now from main menu.

Part 4: Final Steps

Step 16: Install BusyBox from the Play Store. Grant it SuperUser permissions and follow on-screen instructions.

Step 17: Launch the SuperUser app from your app drawer and update binaries from [wrench icon] > Su binary > Update.


The method for rooting AT&T’s Galaxy S III involves the same steps as above but uses different files. Please be careful about using the correct files; you may brick your device otherwise.

Step 1: Follow Part 1: Initial Setup above.

Step 2: Follow Part 2: Flashing clockworkmod.tar but, instead of clockworkmod.tar, use fixboot.tar [MediaFire].

Step 3: Follow Part 2: Flashing clockworkmod.tar but, once again, use this recovery image file [Direct Link].

Step 4: Follow Part 2: Flashing clockworkmod.tar, Part 3: Flashing SuperUser and Part 4: Final Steps (in that order) as it is.

  5. I'm the same way I do my best to remain neutral. It's hard if you communicate with the person the other person dislikes then you fall out of favor with them! I simple can't dislike a person just because someone else does I just can't.
