The official firmware is now available for download via OTA as well as Samsung KIES in Russia, while other countries may have to wait a bit longer.

Nevertheless, those who missed the OTA update notification and those who cannot wait for the official release in their country can install the same manually, using our step-by-step guide. As this is an unbranded firmware (independent of carrier network), it can be installed on any unlocked Galaxy Grand Duos phone.

Key Points to Note

• Verify appropriate USB drivers are installed for the device on computer (download Galaxy Grand Duos I9082 USB drivers)
• Ensure USB debugging mode is enabled on tablet by navigating to Settings > Developer Options (if device is running Android 4.0 or later) or Settings > Applications > Development (if device is running Android 2.3 or earlier).
• Ensure phone has at least 80% battery charge to prevent unexpected device shutdown (due to battery drain) while installing ROM.
• Ensure both device and its bootloader is unlocked.
• After firmware installation, if device is stuck at booting or experiences boot loop issues, Wipe Cache Partition and Wipe Dalvik Cache a few more times before rebooting.
• Allow newly installed ROM to stabilise for five minutes before using the device.
• If aStatus 7 error message flashes while installing firmware, it could be due to an incompatible device or absence of a necessary kernel (for instance, a Jelly Bean Kernel must be installed before installing any Jelly Bean ROM).

How to Install Official Android 4.2.2 XXUBMGA Jelly Bean OTA Firmware on Galaxy Grand Duos I9082

Step 1: Download Android 4.2.2 I9082XXUBMGA Jelly Bean OTA for Galaxy Grand Duos and Odin v3.07 on your computer.

Step 2: Extract the firmware zip file to the desktop to obtain a .tar.md5 file.

Step 3: Extract Odin zip file to get Odin3 v3.07.exe as well as few other files.

Step 4: Power off the phone and wait for vibration (about 5-6 seconds) to confirm complete device shutdown. Then boot the device into Download Mode by pressing and holding Volume Down, Home and Power buttons together until a construction Android robot icon with a warning triangle appears on screen. Then hit Power again to progress into Download Mode.

Step 5: Launch Odin3 v3.07.exe that you extracted in Step 3 as an Administrator, as Admin privileges are required to complete the installation process smoothly.

Step 6: Connect the Galaxy Grand Duos to computer via USB cable, while the device is still in Download mode. When the device connects successfully, a message saying "Added!" appears in ODIN and the ID: COM box will turn yellow or blue with the corresponding COM port number. If the message fails to appear, try reinstalling the phone's USB drivers or changing the port on computer.

Step 6: Choose the following files from the extracted I9082XXUBMGA firmware folder obtained in Step 1 by using respective checkboxes:

• Select the PDA checkbox, and click the '.tar.md5' file
• Tap the Phone checkbox, and select the file named 'modem' (ignore if such file is not found)
• Choose the CSC checkbox, and click the file named 'CSC' (ignore if there is no such file)
• Click the PIT checkbox, and choose the '.pit' file (ignore if the file is missing)

Step 7: In Odin, enable Auto Reboot and F. Reset Time options by selecting the checkboxes. But the Re-Partition checkbox must be selected only if a .pit file was chosen in previous step.

Step 8: To prevent ROM related errors, verify Step 6 and Step 7 are done correctly. Then hit START button to begin flashing firmware.

Step 9: Once the firmware installation is complete, the phone will reboot automatically and soon a PASS message with green background appears in the left-most box at the very top of Odin. Wait until the home screen loads up. Now it is safe to unplug the USB cable to disconnect the device from computer.
