Warranty may be void of your device if you follow the procedures given on this page.

You only are responsible for your device. We won’t be liable if any damage occurs to your device and/or its components.


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


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-I337!

Do not use the procedures discussed here on any other Galaxy S4 (including the Galaxy S4 variant at T-Mobile, US Cellular, Verizon, Cricket and other International variants) or any other device of Samsung or any other company. You have been warned!


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.



You must have proper and working driver installed on your windows computer to be able to successfully flash stock firmware on your AT&T Galaxy S4. In case you’re not sure, follow the link below for a definitive guide for installing driver for your Galaxy S4 on your computer.




Download the Odin zip file and firmware rar given below. Transfer both Odin and firmware file to a separate folder on your computer just to keep things tidy.


DOWNLOAD LINK | File name: Latest Odin3 (951 KB)


DOWNLOAD LINK | MIRROR | File name: I337MK2_Combined_Odin_Tar.rar (1.3 GB)


  Example video: If you haven’t used Odin before to install a stock firmware or anything else, then we suggest you first watch a video of that to get familiar with the process. The video demonstrates flashing of CWM Recovery on Galaxy S4, but since the procedure is same for flashing stock firmware also, the video will helpClick 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 stock firmware, which might delete internal sd card too, your files will remain safe on PC.

  1. Extract/Unzip the Odin zip file, Latest Odin3 on your computer (using 7-zip free software, preferably) to get this file: Odin3 v3.09.exe
  2. Extract/Unzip the Firmware zip file, I337MK2_Combined_Odin_Tar.rar on your computer (using WinRAR free software, preferably) to get this file: All-In-One-i337Mk2-tar.md5
  3. Move the firmware file, All-In-One-i337Mk2-tar.md5, in the same folder in which you extracted Latest Odin3 (Just for your convenience, that is). So, now you’ll have the following files in that folder:
    • Odin3 v3.09.exe
    • All-In-One-i337Mk2-tar.md5
  4. Disconnect the Galaxy S4 from PC if it is connected.
  5. Double-click the Odin3 v3.09.exe file to open Odin.
  6. Boot your AT&T Galaxy S4 into Download Mode:
    • Power off your phone first and wait for 6-7 seconds after display is off
    • Press and hold these 3 buttons together until you see Warning! screen: Volume Down + Power + Home
    • Press Volume Up now to continue to Download Mode
  7. Connect your Galaxy S4 to PC. Odin window will show an Added!! message in bottom left box. Odin’s screen would look like this:
    If you don’t get the Added! message, here are some troubleshooting tips:
    • Make sure you have installed driver for Galaxy S4 as said above in.
    • If you have already installed driver, then uninstall them and re-install 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 phone and PC and then try again.
  8. Load the firmware file (extracted in Step 2) into Odin as instructed below:
    • Click on the AP button on Odin and select the All-In-One-i337Mk2-tar.md5 file (from step 2). Your Odin window should look something like the screenshot below:
  9. 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.)
  10. Double check the above two steps.
  11. Click the Start button to begin flashing stock firmware on your AT&T Galaxy S4 SGH-I337, and wait until you see a PASS! message in Odin’s top left box.
  12. When you get PASS! message, your phone 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 Galaxy S4 from PC, close Odin, remove phone’s battery and put it back inside in 3-4 seconds, open Odin and then repeat from Step 6 of this guide again.

Also, If device is Stuck at setup connection or on any other process, then too, try this: disconnect your S4 from PC, close Odin, remove phone’s battery and put it back inside in 3-4 seconds, open Odin and then repeat from Step 6 of this guide again.

  • 12EYEIN .

    I got a big fat fail! of course. I have this version and now my phone wont get past firmware error use kies to install recovery. I tried the pull the batery and do it again and still didnt work what now?

    • If your phone is prompting you to use Kies, why not try that?

      • 12EYEIN .

        keys wont connect to my phone.

        • Okay, if Kies isn’t working then only Odin can help you. When you followed the guide above to unbrick your phone, did you get the “Pass” message on Odin?

      • paulette

        when i tried to extract the file from odin it told me binary number error

      • These files copy in Phone or PC?
        1 – Odin3 v3.09.exe
        2 – All-In-One-i337Mk2-tar.md5

  • 12EYEIN .

  • Nonefield

    I have a problem, always that i call anynumber appear “Trinidad and Tobago”, how i can disable this?

    My phone is same phone, Samsung S4 SHG-I337

  • Jaime

    Does this prevent the phone from updating to the latest and greatest version? I want to stay at Jellybean and not have it move. Is that possible?

  • paulette

    i tried and it said Binary number invalid

  • nikhail

  • Leighton

    Thank you so much. I have been trying to do this for MONTHS and this is the only method that worked. It would have been nice to not lose all my data, but I’m just glad I’m not stuck in android 4.2 anymore.
