Pre-Requisites:

• A lack of battery power can interrupt the firmware flashing process. So make sure that your Galaxy Grand Duos is charged at least up to 60% before moving further.
• Ensure that a complete backup of all your important phone data and settings has been taken since everything will get wiped out after flashing this firmware. So a backup of contacts, apps, messages, call logs, memos, and APN settings, etc. is highly recommended before proceeding ahead.
• Make sure that you have installed mobile-specific drivers on your computer to detect your phone when you connect it to your computer. You can install them from the Samsung Kies CD which you’ve got at the time of purchase or just manually install them from the link given below.

1. Download the latest Samsung USB Drivers.

• (Optional) Disable all the security tools as well as antivirus that are installed on your computer temporarily. They may increase the risk of interruption during the firmware installation process.

Procedure to install Android 4.2.2 firmware on Galaxy Grand Duos

Downloads:

1. Odin3-v3.12.7
2. Android 4.2.2 Jelly Bean XXUBNG3

Procedure:

Step 1: Download and extract both of the above files to a convenient location on your computer. After extracting the firmware package (.zip file), you’ll see these two files in it:

Step 2: Then power off your Galaxy Grand Duos and boot it into downloading mode.

Step 3: For booting into download mode, press and hold the ‘Home button + Power button + Volume down key’ simultaneously until you see a warning message. Leave all the keys now once you see the warning message window.

Step 4: Keeping your phone as it is, connect it to your PC using the micro USB cable. Now just press the Volume up button to continue. This will directly land your Galaxy Grand Duos into downloading mode.

Step 5: On your PC, launch the downloaded ‘Odin Multi Downloader3-v3.12.7′ software which you’ve just received after extraction. As soon as you open it, the ID: COM section located at the top left corner will turn light blue. Also, an Added message will appear in the message box window. This will confirm that your Galaxy Grand Duos has been successfully connected to your PC.

Note: If such a thing doesn’t happen then it’s more likely to be a problem with the mobile-specific drivers. So just confirm whether you’ve properly installed the mobile-specific drivers on your computer or not. You can install them via Samsung Kies or manually install them from the links given in the Pre-Requisites section. If the problem persists try changing the USB cable or the USB port.

Step 6: Then select the Options tab present on the Odin window and tick the Auto Reboot and F.Reset Time options. Tick only these two options and leave all the other options as they are.

Note: Do not tick the Re-partition option as it may increase the risk of bricking your device.

Step 7: Now, click on the AP button present on the Odin window and browse to the firmware package file which you’ve downloaded (I9082XXUBNG3_I9082ODDBNG1_I9082DDUBNB1_HOME.tar.md5) and select it.

Step 8: Now you need to initiate the firmware flashing process. For doing that, just press the Start button located on the Odin window.

Note: Your phone will automatically boot itself while the process goes on. Do not disconnect the micro USB cable as it will interrupt the firmware flashing process.

Step 9: It will take hardly a few minutes for the firmware flashing process to get complete so wait and be patient. When the flashing process completes successfully, the ID: COM section on the Odin window will turn green with the message ‘Pass’ on it. On the other side, your Galaxy Grand Duos will restart itself automatically. This will confirm that the official Android 4.2.2 XXUBNG3 Jelly Bean firmware has been successfully flashed on your Samsung Galaxy Grand Duos GT-I9082 smartphone. Now you can remove the micro USB cable to safely disconnect your phone from PC.

Note: If this process fails or if Odin gets stuck or in case your phone gets stuck into the boot loop, then close the Odin window, again go into downloading mode and implement the same procedure as given above.
