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

Having problems with custom ROMs?  Or perhaps you want to just return your AT&T Galaxy S3 SGH-I747 back to AT&T for warranty purposes?

No worries, it’s easy to unroot/unbrick your AT&T Galaxy S3 SGH-I747 completely back to stock.  Follow these directions here and you will be good to go in no time.

If returning your phone for warranty, you can try running TriangleAway app to reset your binary counter.  SGH-I747 isn’t supported at the moment by TriangleAway app as of this writing but might be by the time you read this.  After that, you can run ODIN, as this unroot method doesn’t increase binary count.

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

Step 2. When your screen turns off, let go of the Power button but keep holding down Volume Down and Center Home buttons.

Step 3. When you see the warning screen, hit Volume Up button.

Step 4. Connect a microUSB cable from your phone to computer.

Step 5. Next, download ODIN and AT&T Galaxy S3 SGH-I747 Stock ROM files:

Download ODIN
Download AT&T Galaxy S3 SGH-I747 Stock ROM

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

Step 7. PLEASE DO NOT TOUCH ANYTHING ELSE but click on “PDA”, then choose the file “I747UCALEM_I747ATTALEM_I747UCALEM_HOME.tar.md5” then hit “Start”.  THAT’S IT!

Step 8. After about 10-15 minutes, your phone will reboot.

Step 9. Once rebooted, you should find a completely stock ROM back on your Galaxy S3 SGH-I747!

Step 10. If for some reason you get any kind of errors, bootloops, or want to reset everything back to stock, you can do a factory reset.

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

Step 11. Once the screen goes off, let go of the Power button but keep holding down Volume Up and Center Home button.

Step 12. Once in Android system recovery, choose “wipe data/factory reset”, hit the Power button, then choose “Yes” and Power button again.  Then reset your phone.

Step 13. Your phone will reboot and be completely back to Day 1.

Remember, you still have to backup all of your personal photos, videos, and other files in your internal storage/microSD card and erase them if you are going to return your phone for warranty.


Q: ODIN does not start at all.
A: Your Windows computer probably has some driver interference, the quickest solution is to try another computer.

Q: ODIN fails in the middle.
A: Make sure you are not connected to your computer via USB Hub.  You can reset your phone back into ODIN Download mode and try again.  If all else fails, TRY ANOTHER COMPUTER.

    I think I might of screwed myself.

    Like a dummy I went and rooted my Canadian SGH-I747H with your instructions (Rogers Canada). All went well, but when I went into the city today (first time with new phone). It only showed 4G not LTE as per manual (my daughters phone in same locations shows LTE (is a Galaxy II LTE HD). So I am wondering what I have done to the settings? Would that still be LTE? Funny the manual showes LTE not 4G on the phone icon (symbol according to the manual). I tried to unroot the phone and of coarse it would not. I imagine due to the fact that the backup rom provided is AT&T and not Rogers. I tried several times and with several computers no hub. Nothing running in background.

    Any suggestions?

    Thank you in advance


    • Max says:

      Not root related, root does not touch your radios, probably just your settings or just the network.

      • John says:

        Hi Max,

        Yes, sorry you are right. The radio problem was finger problems. The tech had me install my old sim card from my IPhone 4 and it is/was not a LTE card. An as I have found out since your root for Rogers phone (SGH-I747H) AT&T worked perfectly.
        So thank you for your time and the effort you put into this.

        On a side note for the fellow Canadians the unroot does not seem to work with that AT&T rom but it did work with the one I got at the above mentioned web site (again not giving link without permission.

        I will again be rooting the phone, and it is a joy having people like you around to assist.

        All the best.


    • aki says:

      Im using I747UCLH9 4.0.4 , can I flash via Odin directly with SGH-I747 ATT I747UCDLK3 4.1.1 is this stock rom too? thnx

    • rod says:

      are there any free programs to unzip files

  2. John says:

    Think I have found my own answer. On another website (with respect to this sites owner/operator) I will not give the link but the Canadian orig. are at xda.

    but I just cant, I keep getting to download botton, and something like, this TOKEN!!!496269225

    every time I try to download the file, can you help me., thank you

  6. Matt M says:

    I’ve tried downloading the stock rom both from my office pc and my phone and keep getting the download page after I wait the 5 seconds and click download. Any ideas?

  7. Eric says:

    Sorry If you already answered this, but does this work for the Rogers Samsung Galaxy S3 in Canada? Please let me know as soon as possible thank you

  8. Edward says:

    Hi Max, I tried installing the tuchMi rom and I’m stuck in a boot loop.. For whatever reason I cannot boot into clockwork recovery, all I get is download mode. So I tried to use odin to flash back to stock rom but it keep failing on me, even when i try another computer. Please help!! thanks!

    • Max says:

      If you can’t get into clockworkmod recovery and go to download mode, you are probably using Volume Down instead of Volume Up. Think “Down” for “Download”, so Volume Down and Recovery is the other.

      You can try a fresh re-install it should work.

      • Edward says:

        Oh, man… thankyou. I diddn’t realize that the volume up was the way into recovery. I tried to clear the cache’s but still wont boot. How can i do a fresh reinstall?

        • Edward says:

          Edit* It did finally boot, but the setup crashed. so i still probably need to go back to stock. just not sure how…?

          • Max says:

            restore ROM! I hope YOU MADE A BACKUP?!?

          • Edward says:

            sorry for the long string… but I did make a backup like you sugested, how do I reload that backup?

            • Max says:

              Boot into CWM Recovery, hit Backup and Restore, hit Restore, hit the folder with timestamp. *facepalm*

              • Edward says:

                Lol.. i know how silly it sounds.. but It dosen’t work. it just says no files found. I can assure you that the timestamped file is on the SD card. *bangs head against table* lol

                • Edward says:

                  Ok i Figured it out. Clockwork mod wouldn’t read the files becuase I diddn’t have the files in the correct directory. They Must be in Clockworkmod/backup/*timestampfile . otherwise the recovery won’t be able to find the files… I do appreciate the help max! you are gentleman and a scholar!

                  • Max says:


  9. Matt says:

    This worked perfectly for me. After stock was reinstalled I had to do a factory wipe but other than that it was flawless. I did mine so that I can exchange it tomorrow (or later today if its past 12am) for the red GS3 on AT&T instead of my blue one. I was told I could by an AT&T rep as long as it was 30 days between the time I did it and the time I bought it.

  10. Bara says:

    I’ve done everything you said and I’ve been stuck at this step for the past 45 minutes:

    Enter CS for MD5..
    Check MD5.. Do not unplug the cable..
    Please wait..
    I747UCALEM_I747ATTALEM_I747UCALEM_HOME.tar.md5 is valid.
    Checking MD5 finished Sucessfully..
    Leave CS..
    Odin v.3 engine (ID:8)..
    File analysis..

    Firmware update start..
    NAND Write Start!!

    It’s set to auto reboot and I didn’t touch anything else….what do I do???

  11. fadi says:

    hello bro i have problem which is after pressing start in the odin page it stopped and not continuing the process on NAND write start and did not continue so please if u can provide me some information how to handle it

  12. Simon says:

    I tried unrooting my phone, but when I got to the part where I chose recover file I only have this, RecoveryGalaxyS3USCanada.tar, as an option.. I’m on Bell. Its never unrooted. Said pass, and all that. But still have SU permissions

    • Steve H says:

      You have to unzip the file that you downloaded and unzip them to the folder that has that recovery img in it then when u click on PDA in Odin mode you should see one other file there and that’s the one you click on.

  13. Simon says:

    Yeah I did that… There is only the one file in there after initially rooting it

  14. Simon says:

    GalaxyS3RootUSCanada.ZIP, odin3 v1.85.exe, Odin3.ini, RecoveryGalaxyS3USCanada.tar, and SuperUser.ZIP are in the folder in extracted to

  15. Simon says:

    Didn’t watch the video, where he mentioned… Getting ROM now, I’m sure it will work.

  16. Eduardo says:

    There was download link for video How to Root AT&T Galaxy S3 SGH-I747! but not one for How to Unroot AT&T Galaxy S3 SGH-I747!. Phone is rooted, but just in case I need to reverse it…


  17. blair says:

    so ithink i may have messed mine right up

    attempting to unroot because the root failed and the phone will no longer boot up

    during the odin install it gets stuck at this

    then it either crashes or fails

    but now my phone wont do anything except boot to the download screen (vol down pwer home)

    i cant do anything else not even boot to the recovery and kris cant detect it either..HELP!

    • Dan Bara says:

      Make sure Kies is totally closed out, go to the download screen and plug in your phone, then launch ODIN, and load up the recovery image…

  18. Chris says:

    how can i root my samsung galaxy s3 sgh-1747 on mac os x . i have look all over the internet for a solution but everyone still seems to be stuck on only putting out pc compatible roots. please help

  20. Oliver says:


    You my good friend deserve a medal for being a true hero. I just bought my Galaxy S3 earlier today and rooted it with no prior knowledge in customization whatsoever. Long story short, I fucked up my Galaxy S3 pretty damn bad when I deleted some files without backing it up. I’ve been searching for a solution for hours on end and you, my savior has finally pulled me out of this huge ass hole I dug myself into. For that, I am much grateful for people like you who use up their precious time in order to make videos to inform those less intelligent. Please accept this as a token of my gratitude. I wish you the best in life.

  21. Alex says:

    Hey Max!

    first off thanks for your videos man you have helped me out big time. Here’s my question – my volume down button doesn’t work anymore and in order to return it back to Rogers I need to unroot, etc… what would you recommend? I thought i was just able to boot into clockwork and install the stock rom… and then i saw this. haha

    thanks for your time my friend you’re doing a great thing. 🙂

  22. Adam says:

    I went through all of the steps that was shown and everything seem to go fine but now my phone will not turn on or do anything. It showed that its passed and the process went fine but my phone never rebooted and now wont do anything. I tried to remove the battery but that hasn’t helped either. Is there anything else I can do?

    • Max says:

      Does screen turn on?

      • cori says:

        hey Max
        my phone did the same thing, everything passed green, but it never booted up and now its just black screen, i plug it in the red led doesnt even come on any idea what happend?

        • Charles says:

          Does the red light come on when connected to a power source? If not then I would suggest you look at either the USB cable or the battery. Most devices with a USB 2.0 connector are micro USB and compatable with the GS3. If the USB cable works and the red charge light comes on then allow the phone to charge for a while, you may have a battery that just went tango uniform on you. You may need to look into the download mode dongles for the captivate these will force the GS3 into download mode just like they did on tje captivates. Good luck and let me know if you fix it.

          • cori says:

            if i take out the battery and plug the wire the red light comes on, but its not even that the battery was full when i was unrooting it, i followed the steps on odin everything worked it said passed (green) but it just never booted. I am unable to bring it into any mode it just stays black screen but if you plug it into a computer it make a fail noise or the noise when you unplug a usb.

  23. Justin s says:

    Hey – i just put back my rogers rom back on my s3, but all it does not is it loads up and gets to the samsung screen and just stays there with the blue colors fading in and out? When I used odin it passed and on first load up, the green android dude appeared and it was loading with a status bar which also succeeded.

    • Max says:

      Just do a factory reset. That will erase everything in your internal storage though. if you don’t want to lose anything, you can reflash recovery (like you did when rooting), reload a custom ROM to get your phone booting, backup and try unrooting again.

    I just went and followed all the steps to unroot my phone but i am stuck on sbl2.mnb. it does not say pass or fail. what should i do?

    Hi I have a question, I did everything in the instruction and I got it back running on stock, but somehow the superuser app is still there, does that mean my phone is still rooted ?

    What am I missing here ?

    • Max says:

      If you didn’t do a factory reset that is probably why, try doing a factory reset but make sure to make backup of your internal storage beforehand!

    Hey Max,

    Need you help ASAP,
    I downloaded and installed Beats Audio on my Galaxy S3 I747, it rebooted my phone and now it is stuck at the SAMSUNG screen. The only computer that I have is a MAC, so is there any way to unbrick my phone. I use this phone for work purposes.

  44. Charles says:

    Go into recovery mode and do a factory wipe, (ensure that you get the cache) that should wipe out the beats audio, however, unfortunately everything else will be gone too.

    Forgive me if you have already answered this question but I followed this video to the letter and now after it has restarted it is telling me that “Unfortunately, the process android.process.acore has stopped.” as well as not being able to load galleries and TouchWiz failing as well. Is there anything I can do to fix this or did I just brick my phone… Please help as I am panicking.

    • Daniel Min says:

      My phone is
      AT&T galaxy s3

      • Charles says:

        Can you get into the device itself? If so is Debug Mode turned on? Toggle Debug mode off if it is on or on if it turned off. Were you using a custom ROM prior to the attempt at unroot? This maybe a the root of your issue, search the forums where you found the ROM for a solution. Is your battery fully charged before attempting unroot? Battery should have a decent charge in it before attempting anything with Odin.

  51. John says:

    Hey max I made a backup if stick but it won’t get pass system boot.

  52. Shaan says:

    Will this erase all of my data, in other words, will this factory reset everything even if I don’t hit “Factory Reset”?

  53. ThePirate says:

    Hi Max, first off thanks for all your amazing, easy video’s, i ALWAYS use them for all my devices and have NEVER ran into any issues!! I have a quick question, i rooted my AT&T S3 and only put a custom recovery, no ROM’s or kernels etc.. I’d like to do the official JellyBean upgrade , can i just flash a stock recovery then use KIES or must i download then flash the stock ROM? Thanks for everything you do for us!!

  54. Chad says:

    Well I used triangle away to reset my binary then I used odin to reset my firmware back to stock to unroot it, and I did the factory reset, but my device still shows modified in the status settings. Is there a way to correct this? In odin mode on the device it still shows official though.

    • Charles says:

      Modified will always show when you have a rooted device, triangle away->factory wipe->Cache wipe-> flash back to stock and poof now shows “Normal”.

  55. Paul says:

    Hey Max I got a quick noob question which someone probably have asked this but I rooted my phone with still the stock rom no changes whatsoever. I want to unroot it to get jelly bean…… is there a way to just use an update while my phone’s rooted ie: kies air? Or I really have to unroot it, update and root it again? Please reply back and if I unroot it, you said it doesn’t change anything unless I have a custom rom?…….so my pics/music/ apps, etc etc are all there as well as my messages of my text?

    Please reply back as soon as you can thanks………
    btw I used your method to root it =) thanks for making it so simple

  56. Charles says:

    No need to unroot if you use the Triangle away app. SuperUser will still show up in your app drawer but will not be usable until you redo the root.

  57. MFC says:

    I unroot my SGS3 with Rogers stock file, all went ok, it rebooted but still I have SperUser icon and it ask for GRANT access for some of the Apps on my phone.. FYI -I did unroot to install new SW version but while suing KIES its goes off after some time asking Samsunf AdminDelgator and its stop. Did I did any thing wrong…why I am not bale to update new SW.

  58. MFC says:

    Sorry previous question had some typo error

    • Charles says:

      If you flashed the stock ROM SU should be gone. You then should be able to open Kies and update at that time. If you are not using a i747 device then the update may not be available to you. Is the update available on Rogers?

  59. justin says:

    Is there anyway to do this with mobile Odin?

  60. Dan says:

    Hi Max and everyone,

    Can anyone help me fix the problem? After unroot my galaxy s3 (AT&T) it not boot up and hang at “SAMSUNG” logo. Very appreciated for any help.

  61. Charles says:

    This is a common issue with custom ROMS when you don’t do a cache wipe and a factory reset. Since this is a stock ROM go into recovery mode (power the phone off then hold vol up, home, hit power button until you see the Samsung logo then release the power button and continue to hold vol up and home buttons; after the Samsung logo you should see the recovery screen come up.) There is a factoey restore option there.

  62. Dan says:

    Thank so much for quick reply. I did exact what you said and not getting better (problem still there). Anything else I can do ?

  63. Charles says:

    Have you attempted a reflash back to stock?

  64. Charles says:

    Are you running an i747 or another version of the S3?

  65. Dan says:

    Yes I did and it say PASS. It took 7:22 to finish the process.

  66. Dan says:

    Ooop !! good news. It boot up now 🙂 . Thanks a lots for your help. You the man.

  67. Charles says:

    Good to hear, first boot always takes longer than subsequent boots.

  68. wilfredo Pagan says:

    i just unrooted my phone and it says
    Unfortunatelhy, the process
    android.process.acore has stopped.
    it stays like that .
    what should i do?
    thanks in advance

    • Charles says:

      Do a factory wipe and cache clean then re-download the stock ROM then redo the install, your stock ROM that was downloaded before may have been corrupted.

  69. FANC says:

    i have a Canadian rogers gs3 and am using your link for stock rogers touchwiz with he this process but when i go to pda on odin and click the .md5 file in the stock rogers file it brings me back to odin with a check mark on pda but nothing written in the text box next to pda so im wondering can i just select the whole stock rogers file or what should i do

    thank you very much i appreciate your help

    • Charles says:

      Take a look at the box on the left in Odin, does it show the file as verified or is there an error in there? What version of Odin are you using, 1.7 seems to work the smoothest and the 3.x seems to have some wierdness and issues.

      • matt says:

        im not sure what box your taking about but there is nothing written any wehre when use the pda file from the stock touchwiz folder also i took your suggestion and downloaded odin 1.7 and still the same problem do you have any other suggestions

        thanks for taking the time to help me matt

  75. Daylan Dean says:

    Hey I’m a newbie as well but I was successful at rooting my samsung Galaxy S I-747 with AT&T. I’m not advanced enough to flash roms or kernels yet but I have all the apps and other misc rooting apps. I want to upgrade to jelly bean but being rooted I can’t so I seen ur video on unrooting and then doing the update so I’m considering it. Also as I said I’m a newbie with Android and rooting but do u or anyone know where I can find support with (once my phones rooted) all the root apps like Set CPU, Busy Box, ROM Manager, Titanium Backup, Busy Box Installer, market unlocked, Black market apps, super user and the difference between each one, 4 EXT Recovery, rom toolbox, etc? Is it possible to link black market downloaded apps to Google play? I just really need a Android Pro to contact me so I can really pick his brain and get a better understanding of all this bc I am truly interested and anxious to know more. Anyone is welcome to contact me if they have advice and I’ll try not to annoy u with too much, LOL! Sorry for hitting u up with all that but just notifying all the Android developers out there that do awesome jobs but us newbies don’t understand their terminology or maybe it’s just me. We need more blogs and videos on all those root apps I listed, just saying it would greatly help. I had a HTC Inspire and got it rooted and flashed a rom but that’s bout I… That was the first experience with android and rooting. I have to say ANDROID is the shit and blows I phones out of the water!

  78. Marty says:

    Max, I have had no issues rooting unrooting. I have tried to completely unroot my Galaxy S3 SGH-I747. BUT after rebooting with odin & I checked the triangle away before rooting it did say original. When i just tried to unroot – worked fine but if i look at the ‘about device’, Status, Device Status indicates that is still modified. Do I have to do to take it back to original here also. Company makes me run afaria for company email. it keeps locating that i have modified my galaxy s3

      Try on another USB port, and make sure you are not using a USB hub, if all fails, try another computer, it will work eventually.

    Hi. Just about finishing up with unroot, (went smooth, started with Triangle away then Odin, got the green PASS) phone autobooted as shown on video, AT&T logo passed – silently (the first sign of something may have gone wrong), SAMSUNG word came to display again, blue LED lits, and ever since it froze at this point for the past 20 minutes. I tried rebooting, it did, stuck at the same point. Pulled the battery, rebooted, stuck at the same point. What to do??

  85. Zee says:

    Never mind. – After waiting another 20 minutes, I gone through that feeling of almost passing out, cramping in the stomach, so then I decided to manual reboot to factory reset. It did – Yippees! Sound is back when AT&T logo comes up, auto AT&T update is done, phone is back to life. Fortunately, I backed up everything. Though the phone is back, empty and I can reload everything, can you tell what in the name of God went wrong??

  86. Moe says:
