How to Root AT&T Galaxy S3 SGH-I747!

For those of you who want to root your AT&T Galaxy S3 SGH-I747, here’s a step-by-step guide plus video tutorial (using SGH-I747).  Anyone with even slight knowledge of computer should be able to do this easily.  This guide is noob-proof and my suggestion is to follow the video and the guide one step at a time.

UPDATE: PLEASE SEE UPDATE NOOB-PROOF FAIL-PROOF GUIDE HERE INSTEAD!!!

Step 1. Hold Down Volume Down, Center Home, and Power buttons together for about 10 seconds.

Step 2. When your phone resets (screen goes off), let go of the Power button but keep holding down the other buttons.

Step 3. When you see a warning screen like below, hit Volume Up button.

Step 4. Once in Download mode, connect microUSB cable from your AT&T Galaxy S3 SGH-I747 to your computer.

Step 5. Download GalaxyS3RootATT.zip and unzip, you should fine 4 files and everything you need to root your AT&T Galaxy S3 SGH-I747.

Step 6. Double-click on the file “odin3 v1.85.exe” to start the ODIN program.  You should see a yellow-highlighted box with a number.  If you don’t, download and install Samsung Kies, then unplug/plug your phone back in; you should see it now.

Step 7. PLEASE DON’T TOUCH ANYTHING ELSE but click on “PDA” then choose the file “CWM-Recovery.tar” and hit “Start”.  That’s it!

Step 8. You should get a “PASS!” and your phone will reboot.

Step 9. Once rebooted, copy the file “CWM-SuperSU-v0.87.zip” to anywhere on your phone.

Step 10. Hold down Volume Up, Center Home, and Power button together for about 10 seconds.

Step 11. Once your phone resets (screen goes off), let go of the Power button but keep holding down others.

Step 12. Once in ClockworkMod Recovery (also known as CWM Recovery), choose “install zip from sdcard”.

Step 13. Next choose “choose zip from sdcard” or “choose zip from internal sdcard”, depending on where you copied the file over to earlier.

Step 14. Choose the file “CWM-SuperSU-v0.87.zip”.

Step 15. Choose “yes”.

Step 16. You should see something like below:

Step 17. Reboot your phone and your AT&T Galaxy S3 SGH-I747 is now fully rooted and with SuperSU app, which is the Superuser app.

FAQ

Q: Does this root method erase my settings and apps?
A: No, it doesn’t touch a thing, very safe to do.

Q: I ended up in Kernel panic mode, what do I do?
A: Relax, that’s same as ODIN download mode, simply run Heimdall again and flash the files again, it will work.

Q: I don’t get ClockworkMod Recovery like you do, just get Android with belly open.
A: If you’ve updated to newer software update, the stock OS will over-write ClockworkMod Recovery on reboot.  To fix this, make sure “auto-reboot” is checked off in ODIN, then take the battery out when it’s done flashing in ODIN.  Then enter ClockworkMod Recovery right away.

More on this Root Method

This root method simply installs ClockworkMod Recovery to the recovery partition and installs Superuser zip file, very safe to do.  With Galaxy S2, recovery partition was part of the kernel and was a bit dangerous but with Galaxy S3, Samsung has made recovery parition separate from the kernel, making it much safer just like how Galaxy Nexus works.

    WHAT???? people complain after rooting the wifi don’t work, but this video is the same as the other one, just different phone. i have a ATT galaxy s3 and i root it about 2 hrs ago & my wifi is work fine.

  2. Anselm Mak says:

    Perfect! Thanks for the detailed instructions. Everything went smoothly.

  3. alex says:

    does this trigger the flash counter???

  4. Todd says:

    Awesome website! You made rooting my Note and s3 a breeze! Quick question, I just rooted my AT&T galaxy s3 per your instructions and worked like a charm. However when I tried to use any wifi tether app off of the marketplace, no such luck. Any advice?

  5. Kembric says:

    i have a sprint s3 and when i pick CWM-SuperSU-v0.87.zip on the phone, i get (E:signature verification failed). when i bought the phone on june 3 the phone made me do an updata. do you think the updata has anything to do with the signature verification failed?

  6. submachine0 says:

    so about 2-3 days in and i haven’t seen any issues on stock ROM, if anyone’s worried or anything. there’s info on how to unroot too, plus with that counter-reset thing there’s really absolutely nothing to lose.

  7. kaden sun says:

    Hi, I am stucked at the step 7. It stopped at recovery.img and wont’ go any further. please help.

  8. daniel says:

    lol nvm unplug your device and plug it back in
    worked

  9. Russ says:

    Hi Max, great video!! I can tell that my phone is rooted because I can now run Titanium Backup…but the superuser icon, #, can’t be seen anywhere. Is that a problem, and if so how would I go about making it appear?? Thanks for your time, and please keep up the outstanding work!!

  10. Russ says:

    Got it…the icon is a pic of Andy with a pirate eyepatch!! “Superuser”. Thanks for the quick reply Max, the SGS3 is my first foray into the Android world, and I’ve already put the fruit company so far in my rear view mirror that I can’t even see them.

  11. sendalot says:

    Hey Max,

    I was able to root my at&t galaxy s3 but I had to return it and I got a new one and on the new one there was an update that at&t pushed and now I can’t root it. Did someone else experience this?

  12. Russ says:

    Hey Max, I’m guessing that this is not your “regular” job. Your knowledge and quick responses go above and beyond…is there a way to “donate” to you for your efforts??

    • Max says:

      This is my regular job/online business, I run the world’s biggest free Android support center, call it AndroidSquad if you want. No, I don’t accept donations but if you can convert your iWhore friends to Android that’s all I ask! ;)

  13. Bhaskar says:

    Does this method work with the updated firmware viz. UCALG1?
    I was wondering if this method trips the flash counter.
    Thanks.

    Hey Max I updated my AT&T s3 and I did the unchecking of the auto reboot and removed the battery and the usb cable and I went into cwm. I was able to get my phone rooted. But without my s3 connected to a laptop or pc or do the whole odin v1.85, I am not able to get back into cwm by holding the volume up, home button, and the power button. Please help Max

  20. Karan says:

    My CWM says :

    Reboot System now
    Apply update from ext storage
    wipe data / fact. reset
    wipe cache
    apply update from cache

    It didn’t say anything about applying update from sd card. Could you please help.

  21. james says:

    i got stuch in the odin program at “recovery.img” it just stops all progress and sits there i tried to give it time to finish but even after 30 minutes nothing changed so i just closed program and restarted phone and it still works fine but i want to root it still

    whats the work around for that?

  22. Cambodia says:

    AT&T Galaxy S3 SGH-I747 What wrong atfer rooting restart phone it show only logo “SAMSUNG” after that close it can’t login to phone window how i can do I didn’t backup my phone, please halpe!!!…………. :-(

  23. JOHN says:

    I have huge problem help ASAP
    I rooted my galaxy s3 i747 successfully and intall EZ unlock.
    while I was having dinner with friends, my battery ran out. now the phone is not working at all.
    I CANT TURN IT ON. TRIED EVERYTHING, FACTORY RESET AND RECONNECT TO ODIN EVERYTHING. ITS NOT WORKING. I DIDN’T DO ANYTHING ELSE. I NEED HELP PLZ.

    • JOHN says:

      WHEN I CONNECT IT TO COMPUTER IT MAKE REJECTING SOUND FOR USB. MY USB CABLES WORKS FIND. I TRIED WITH OTHER GALAXY S3 PHONE. my battery is found sim card is find sd card is find, except the phone.

      • JOHN says:

        CAN SOMEONE HELP ME PLZ

        • Max says:

          EZ Unlock is ONLY for Verizon Galaxy S3, that might be why. You can try unrooting that could fix.

          • JOHN says:

            I Tried unroot, but before I even start everything I can’t even turn it on nor go into factory resetting mode

            • Christian Klager says:

              I had that very same problem, but solved it right away thanks to my high research skills. I found that the Hindu in one video, tells you how to root, but NEVER states that there is a side MOD for at&t. So it fucked up my phone.THEN, I found this website, and magic worked.
              NOW, my problem IS, that when I try to install the SU from openrecovery, it keeps failing to mount sdcard (Invalid Argument)
              Any pointers?
              And dude, you should try instaling KIES on your pc, it’s probably just missing the required drivers to communicate with ODIN, that’s it.

  24. Mark Radwin says:

    Have you uploaded the tutorial for the ATT Samsung Galaxy S3 on a Mac??
    If so, please comment back with the link to the tutorial!
    Thanks!

  25. Michael Bahu says:

    I have a rooted s3 with att. What’s a good hotspots bypass? I have the kyan boot from.

  26. ghazale says:

    I got unlocked at&t galaxy s3, this will work on that too? Wont it lock it again?

  27. Steve S says:

    I have the same problem as the other gentleman when rooting my phone…when i get to the cwm i.e. I get the android with the belly open. Auto reboot was already checked in odin and I tried pulling the battery but I still get the same menu that looks nothing like the one displaying in your video. any other advice? thanks in advance.

  28. StevenHB says:

    I’m having trouble downloading GalaxyS3RootATT.zip. The download site’s page keeps saying “nginx error! The page you are looking for is temporarily unavailable. Please try again later.” Is there anywhere else that I can get the file?

  29. Rick says:

    Hey guys. This may be a stupid question, but will I be able to unroot and flash back to stock without voiding my warranty? I saw someone say something about tripping a flash counter or something and was curious about that too. Thanks for the continued support

  30. Rick says:

    Reply to this one please so answers will go to my email.

  31. Mike says:

    Love the instructions thanks for the help with the video. I tried this first on my own and bricked one. I returned it to the store and got a free replacement. They couldn’t get it to boot at all.

  32. Gabe says:

    I never got the paste option after i copied the zip file, now what should i do?

    using windows 7

    can i do this on a mac?

  33. Gabe says:

    Thanks Max,

    Copying is not the problem I just dont get the paste option. could it be becasue I did it with win zip to open the tar file?

  34. ricky says:

    I had several problems. After rooting, my AT&T service was in and out. Couldn’t check voicemail, didn’t get messages, couldn’t connect to phone calls, then it would connect again for a bit and then go out again. Anyone else have these issues?

    • Sean Asten says:

      I have the same issue. New sim didn’t do anything, nor did AT&T’s customer service lmao…If anyone has a solution it would be very very appreciated.

    • Max says:

      That’s not root related it seems like, rooting doesn’t actually affect any signals, voicemails, etc…etc… You might just have a defective phone, take it back to your AT&T store and get a new phone.

  35. Mark says:

    When I unzip the ROM with WinRAR I don’t get the four options listed I get:
    META-INF
    system
    boot
    installbusybox
    I know this is a stupid question but I don’t know why I’m not getting the same selection as in the tutorial.

  36. jason says:

    could send me the root files? I cannot find it through the internet.

    thank you so much !

    • Joliano says:

      Same here , anyone can help , I know Max super busy.. Thx

    • Joliano says:

      Hey Joel,

      I just tried this .. first be sure the USB Debugging is checked.
      try to root again but this time when u done flash CWM-Recovery.tar in step 7, unchecked auto Reboot and take out the battery and then keep going wz the steps u will see Install there.

  48. Joliano says:

    Max, I did root my I747 before form 5 months ago and I try to reset my phone now as factory data reset.
    And when i try to install Rom manager saying something about my room not rooted , so I try to root again but i cant fined the install part in ClockworkMod Recovery, and I skip this step. ( still my phone status saying Modified)

    I know i did’t keep up wz the new tools all that time, and I screw up. How can I start clean again , and what the best thing i can do now

  49. Venkat says:

    Thanks for the instructions. I had trouble putting the Phone in CWM mode. But later figured it out. If the phone has updated software from AT&T then the CWM mode will not work. The solution is to reflash CWM-Recovery.tar using odin with auto reboot unchecked. Then take the battery out and try entering the CWM mode again. Its volume up instead of down for the CWM mode. I was using volume down (My mistake).

  58. Ben says:

    Great Tutorial! I’m not the most computer savvy person and it was no problem! Only thing, the FAQ about “android belly open/doesnt go into Clockwork mod” it happened to me but the part about “uncheck auto-reboot in ODIN” wasnt clear. I only understood that the uncheck box is located in the ODIN program. Call me dumb but it just wasnt very clear. Also in the written version of this tutorial they forget to mention the part about disconnecting phone from the computer before running the Clockwork mod, only in video is this mentioned and its IMPORTANT to disconnect phone before running it cuz if you dont the process wont work. Besides my two little “bitch complaints” lol everything was great, reccomend for everyone with the AT&T Galxy S3! Thanks to the person responsible for the ROOT and thanks for the person responsible for the tutorial!

  59. Mir says:

    not able to reboot my device in recovery mode!! please help. got through step 9 but at step 10 when I hold down the 3 buttons to go in recovery its taking me to 3e recovery and im not able to flash the superuser zip from there. please help?

  60. cody says:

    Use the updated method I had the same issue once before also remember to pull the battery because the stock recovery overrides cwm, follow it step by step, the updated works very well good luck
