Before you begin with guide 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 SM-N900A!

Do not use the procedures discussed here on any other Galaxy Note 3 (including the Galaxy Note 3 variant at Sprint, Verizon, T-Mobile and other International variants) or 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.

  DOWNLOADS

Download the firmware file given below.

  FIRMWARE ZIP FILE

DOWNLOAD LINK | File name: N900AUCECMLG_OneClickBin.zip (1.5 GB)

  STEP-BY-STEP GUIDE

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 leaked firmware, which might delete internal sd card too, your files will remain safe on PC.

  1. Extract/Unzip the Firmware zip file, N900AUCECMLG_OneClickBin.zip on your computer (using 7-zip free software, preferably) to get this file: N900AUCECMLG_OneClickBin.exe
  2. Disconnect the Galaxy Note 3 from PC if it is connected.
  3. Double-click the N900AUCECMLG_OneClickBin.exe file to open Odin with the firmware file already loaded.
  4. Boot your AT&T Galaxy Note 3 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

  5. Connect your Galaxy Note 3 to PC. Odin window will show an Added!! message in bottom left box. Odin’s screen would look like this:
    Odin 3.09 - Samsung-Galaxy-Odin-Device-Added-Screenshot
    If you don’t get the Added! message, here are some troubleshooting tips:
    • Make sure you have installed driver for Galaxy Note 3 as said above.
    • 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
  6. Click the Start button to begin flashing leaked firmware on your AT&T Galaxy Note 3 SM-N900A, and wait until you see a PASS! message in Odin’s top left box.
  7. 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 Note 3 from PC, close Odin, remove phone’s battery and put it back inside in 3-4 seconds and then repeat from Step 3 of this guide again.

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

    It definitely won’t flash the MLG firmware so you can set it back to Android 4.3 to root it. Time to start looking for a solution.

      Samsung has blocked downgrades now. Yes, very sad thing. Install the 4.4 kitkat firmware back if you haven’t already.

  • tortionist

    This worked quite easily for me. Now i’m going to attempt to downgrade the firmware so I can root via De la vega method. I’ll post results.
