[STANDARD DISCLAIMER: THIS IS A FAIRLY EASY GUIDE TO FOLLOW AND YOU SHOULD HAVE NO PROBLEMS UPGRADING YOUR PHONE. HOWEVER, PLEASE NOTE THAT I AM NOT RESPONSIBLE IN THE EVENT THAT SOMETHING GOES WRONG AND/OR YOU 'BRICK' YOUR DEVICE.]

First off, download the following files

ODIN 3.07: https://www.copy.com/s/wSEoPPbzYXmF/AndroidJinn.com_Odin307.zip

Samsung Firmware:

NEW: GET THE LATEST (Jan 2014) 4.1.2 SAMSUNG FIRMWARE FOR EUROPE (GREECE) FROM HERE

METHOD TO INSTALL ON YOUR PHONE REMAINS THE SAME

EXTRACT BOTH THESE FILES TO YOUR DESKTOP. YOU SHOULD NOW HAVE TWO NEW FOLDERS ON YOUR DESKTOP.

HOW TO UPDATE:

​

Step 1:

Turn off your phone. Wait a few seconds, the phone will vibrate to confirm that it is fully switched off. Connect your Galaxy Music S6012 to a USB port on your PC using the ORIGINAL SAMSUNG USB cable that came with your device.

Step 2:

Go to Odin3 v3.07.exe that you have previously extracted into a folder on your desktop. Right click, and 'Run as Administrator.'

Step 3:

Now, press and hold three buttons at the same time: Volume Down + Home + Power button TOGETHER until you see the following warning message:

Press Volume Up button again to enter into Download Mode. Now your phone's screen will show this:

On the computer, you will see 'Added' in Odin’s message box:

You should also see COM port with a number highlighted in Blue if you successfully added your device. (Com 15 in my case)

NOTE: If you don’t get 'Added' then it means you do not have USB drivers installed for your device. Download from here. Install the drivers and try again. If it still does not detect the phone try another USB port or another USB cable.

Step 4:

In the Odin Window, click the PDA Button, and select the .tar.md5 file from the folder where you had previously extracted the Samsung firmware.

Step 5:

In Odin window, make sure Auto Reboot and F. Reset Time checkboxes are only two that are ticked.

Step 6:

Now, to begin the flashing process, hit the START button. The top left box in the Odin window will turn green and the flashing process will start.

On your phone it will look something like this:

Step 7:

After installation of the system your phone will reboot automatically and you will see a PASS message in the top left box of Odin.

You can now safely unplug your device from computer.

Your Galaxy Music S6012 should now upgrade its apps.

When it starts up, it should run Android 4.1.2 Jelly Bean

Go to Settings > About phone to verify.

Congratulations! You now have your Samsung Galaxy Music Duos running on OFFICIAL Jelly Bean!

Note: If you were rooted before, you will have to root again and re-delete the system apps you may have deleted earlier.Your other apps, system settings and files will still be there.​
