[Guide UPDATED] How to Unroot your AT&T Galaxy S3 (Return To Stock I747UCDLK3 JellyBean )

**Skunkape60** · 10-08-2012, 06:05 PM

If you are unrooting to take your phone to AT&T, you will want to clear your flash counts first. If this is not required you can skip this step.

Always check your current count state in download mode prior to using triangle away. If what Triangle Away and what is shown in download mode doesn't match, do not proceed.

You will be will be resetting your phone with an app called triangle away, which has just been updated to support all US versions of the GS3. Click on the link below to download triangle away.

Click here To download
Please thank

Installation instructions and how to use it are in QBKING77's Video Below.

Here's a one file one flash method to return to stock. This will return you phone to a stock unrooted state. While you will need your drivers and Odin desktop loaded, you will only be flashing a single file to your phone.

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...

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.

Download and install on your computer.

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 UnRoot GS3

After downloading the above files to your computer:
1. double click on the "Odin 3.07 zip". Copy the "Odin307" folder into your "UnRoot GS3" folder.
2. Copy I747UCDLK3_I747ATTDLK3_I747UCDLK3_HOME.tar.md5 to the UnRoot GS3 Folder.[/COLOR][/B]

Using Odin

1. Open the "Odin307" folder and right click on "Odin3 v3.07.exe" and choose run as administrator. Odin will open.

2. place your phone into download mode. Turn off phone - press and hold volume down, home button and power button at the same time. When you see the warning push the volume up button to continue.

3. Plug your usb cord to your phone and computer and wait until you see any number and com in the com box.

4. Check the PDA block and browse to "I747UCDLK3_I747ATTDLK3_I747UCDLK3_HOME.tar.md5" in your UnRoot GS3
Folder

5. Verify Auto Reboot is checked as well as F. Reset Time

When all this is setup Odin should look like this:

6. If everything looks like the picture, click on the start button in Odin.

Note: This is vary large file and make take up to 10 minutes to complete.

When the phone leaves download mod and starts to reboot you can remove the usb cord.

Thanks. Just did this tonight and it worked flawlessly. Longest time was downloading the .tar file. Back to stock/unrooted and was able to update OTA to I747UCLH9.

Do you lose all of your data?

I believe it depends on what version you are coming from but I can't say for sure as I have the sprint phone. I would definitely backup the stuff you can to a computer just to be sure.

**dmachine01** · 12-04-2012, 10:01 AM

worked like a charm and as far as I can see, all my data is in tack.

After you go back to stock how long does it stay on the samsung screen? Odin said I passed and it reset but now it's stuck on the samsung logo with the blue led getting brighter and darker

If this happens, reboot into stock recovery and choose the option to factory reset. Reboot your phone and it will work. 1st boot will take a bit longer.

**ShannonYSL** · 12-04-2012, 11:47 PM

It takes more than 10 mins to reboot
still rebooting...

**Swearengen** · 12-06-2012, 03:33 PM

Thanks for this thread. Is there now a way to unroot directly to an AT&T Jelly Been stock ROM?

EDIT:
I just went back from CM10 to my Nandroid backup of stock (but rooted) AT&T ICS 4.0. Kies is not working to go forward now. I suppose I should unroot to use Kies for the 4.0 to 4.1 upgrade....

OK, I didn't have your thread when I rolled mine back with my Nandroid backup. I see in Triangle Away the current count state, but where is this "download mode" that should match the flash count?

**morecaffeine** · 12-08-2012, 02:23 PM

The link to the .tar file is broken. Is there another?

Try again the link is fine. Please do not attempt to download this from your phone. You a computer with a broadband connection.

Also not if it hangs more than 15 minutes, reboot into stock recovery and perform a factory reset. That will fix the phone from not booting. Yes it often takes 10 minutes on first boot. After that 1st boot it will be back it normal.

To get into download mode press volume DOWN, power and home simultaneously until you see a warning. Then release all and press volume up. It will show your flash counts in the upper left portion of your screen.

Didn't work for me. Tried it twice. After it boots I keep getting "Unfortunately, the process android.acore has stopped."

Try redownloading the tar file and flash in Odin again. Perhaps you got a bad download. Please download on high-speed broad band. Do not use your phones connection.

**rborelli** · 12-10-2012, 07:55 PM

Thanks. I tried all that. Downloading via cable also. The Odin worked fine. Gave me a pass both times. It was when the phone would boot up. I did a factory reset and it came up fine.

I can't use the link for the .tar file either, what does this error mean.

Temporarily Unavailable

This file is temporarily unavailable because there are no resources available under the owner’s account

**Skunkape60** · 12-12-2012, 09:06 PM

Sorry. I ran out of bandwidth and had to buy more. Should be back up now...

**mumbo jumbo** · 12-13-2012, 08:10 PM

So the only.way to unroot is via windows (can't use mac) ?

Or is paralles on mac an option?

Pull out your battery. Put in your battery. Press and hold volume up, power and home buttons simultaneously. Release all 3 as soon as you see the Samsung on the screen. Your phone will boot into stock recovery.

OK. Thanks. I see it there now. I've seen the screen before but the font is so small that I missed the counter there. Also, I had no idea that there could be a different count there than what is displayed in Triangle Away.

Yet, it is good to be able to see your counter once you've reverted back to stock.

Belated Thanks for the file download link as well.
