  GUIDE: ROOT AT&T SAMSUNG GALAXY S3 SGH-I747

Before you begin with the instructions below, make sure your android device is adequately charged — at least 50% battery of the device.

  STEP 0: CHECK DEVICE MODEL NO.

To make sure your device is eligible with this, you must first confirm its model no. in ‘About device’ option under Settings. Another way to confirm model no. is by looking for it on the packaging box of your device. It must be SGH-I737!

Please know that this page is meant only for AT&T Samsung Galaxy S3. Please DO NOT try the procedures given here on other variants of the Galaxy S3 (including the S3 devices at T-Mobile, Verizon, US Cellular and International Ones) or on any other device of Samsung or any other company. You have been Warned!

  STEP 1: BACKUP YOUR DEVICE

Back up important data and stuff before you start playing around here as there are chances you might lose your apps and app-data (app settings, game progress, etc.), and in rare case, files on the internal memory, too.

For help on Backup and Restore, check out our exclusive page on that linked right below.

  CF AUTO ROOT FILE

DOWNLOAD LINK | File name: CF-Auto-Root-d2att-d2uc-samsungsghi747.zip (12.54 MB)

  STEP-BY-STEP GUIDE

  Example video: If you haven’t used Odin before to flash a file on your phone before, then we suggest you first watch a video of that to get familiar with the process. The video demonstrates flashing of a Recovery on Galaxy S3, but since the procedure is same, the video will help: Click here to watch the video

Important Note: Backup important files stored on internal SD card of your device, so that in case a situation arises requiring you to do a factory reset after flashing the CF Auto Root, which might delete internal sd card too, your files will remain safe on PC.

  1. Extract/Unzip the CF-Auto-Root file, CF-Auto-Root-d2att-d2uc-samsungsghi747.zip on your computer (using 7-zip free software, preferably). You’ll get the following files:
    • Odin3-v1.85.exe
    • Odin3.ini
    • CF-Auto-Root-d2att-d2uc-samsungsghi747.tar.md5
  2. Disconnect the AT&T Galaxy S3 from PC if it is connected.
  3. Double-click the Odin3-v1.85.exe file to open Odin.
  4. Boot your Galaxy S3 SGH-I747 into Download Mode:
    1. Power off your phone first. Wait for 6-7 seconds after display is off.
    2. Press and hold these 3 buttons together until you see Warning! screen: Volume Down + Power + Home.
    3. Press Volume Up now to continue to Download Mode.
  5. Connect your Galaxy S3 to PC. Odin window will show an Added!! message in bottom left box. Odin’s screen would look like this:
    Odin 1.85 CF Auto Root Device Added
    If you don’t get the Added! message, here are some troubleshooting tips:
    • Make sure you have installed driver for Galaxy S3 as said above in ‘Before you begin..’ section.
    • If you have already installed driver, then uninstall them and reinstall back.
    • Connect using a different USB port on your PC.
    • Try a different USB cable. The original cable that came with your phone should work best, if not, try any other cable that’s new and of good quality.
    • Reboot your phone and PC and then try again.
  6. Load the firmware file (extracted in Step 1) into Odin as instructed below:
    • Click on the PDA button on Odin and select the CF-Auto-Root-d2att-d2uc-samsungsghi747.tar.md5 file (from step 1). Your Odin window should look like the screenshot below:
      att-samsung-galaxy-s3-cf-auto-root-odin-file
  7. Now in the Option section of Odin, make sure that Re-Partition box is unchecked. (Auto Reboot and F. Reset Time boxes remain checked, while all other boxes remain unchecked.)
  8. Double check the above two steps. (Step 6 and Step 7)
  9. Click the Start button to begin flashing, and wait until you see a PASS! message in Odin’s top left box.
  10. When you get PASS! message, your device will restart automatically. You can then disconnect your phone from PC.

If you see FAIL message instead of the PASS in Odin’s top left box, that’s a problem. Try this now: disconnect your AT&T Galaxy S3 from PC, close Odin, remove phone’s battery and put it back inside in 3-4 seconds, open Odin and then repeat from Step 2 of this guide again.

Also, If device is Stuck at setup connection or on any other process, then too, try this: disconnect your AT&T Galaxy S3 from PC, close Odin, remove phone’s battery and put it back inside in 3-4 seconds, open Odin and then repeat from Step 2 of this guide again.

NOTE: It may happen that your phone doesn’t automatically boot into recovery and root your phone. In that case follow the following above procedure except that in Step 7, Auto Reboot option is un-checked and then the instructions below:

  • Pull out the battery and re-insert it.
  • Boot your AT&T Galaxy S3 into Recovery Mode: Press and hold these 3 buttons together: Volume Up + Power + Home.
  • Now, this will start the rooting process and will reboot the phone automatically when the process is done.

That’s all. If you need help regarding this, feel free to ask us in comments below.

  10. Info-AT&T, I747, CARRIER UNLOCKED, KITKAT-UCUFNJ2, The phone was rooted before but I did the new update from UCUFNJ1 TO UCUFNJ2, I lost root so I’ve been trying to flash ROOT & TWRP RECOVERY, all done with ODIN 3.09, I haven’t found anything to work.. I hope that taking this new update that came out 8/18/2015 has not locked up the ability to root. The info for update was posted at XDA BY ENEWMAN17.
    SO if you have an update from carrier you should search for info before taking this update,,, as I read at XDA all carriers have pushed tbis update out for KITKAT…
