Upgrade Galaxy Grand Duos GT-I9082L with UBAMC2 Jelly Bean 4.1.2

Samsung Galaxy Grand Duos GT-I9082L is sure to function even better compared to its present performance once it gets updated to Android 4.1.2 Jelly Bean. What we would like to use for this tutorial is UBAMC2 official firmware.


Before we give you the exact steps to follow for the flashing of the update, here are pre-requisites: backup the data on your smartphone (also: take the data on the internal memory and back it up, too, to a dedicated hard drive), charge the battery of the device, use the fully unlocked Grand Duos I9082L, install USB drivers for your handset on your laptop and then turn on USB debugging. Should the latter run Linux or Mac, you have to use CrossOver Utility.

Important instructions

  1. Step number one to start this tutorial: download  official firmware and Odin tool 3.07 on your notebook, unzip them and then power the I9082L off.
  2. Step two: the phone should be booted now into download mode; like this: press and simultaneously hold Home, Volume Down and Power. The mode will be reached when you press Volume Up and the I9082L shows you Android’s logo.Galaxy-Grand-Duos-I9082L
  3. For step three you shall need to run Odin .exe (one of the files resulted from first step’s unzipping process) as an Admin; here’s how: right-click on Odin tool .exe, click on Run as administrator from the options list and you’re done.
  4. Step four will ask you this: plug the phone to your PC. After the devices are connected to one another, you need to go to step five.
  5. Which sounds like this: click on the buttons we mention below and opt for the files they’ll open up. Here:

    – click on Phone and a file containing MODEM in its name is going to be available;
    – click on CSC, then select the file with CSC in its name;
    – click on PIT and this file will be displayed: .pit.
  6. The next step to follow, which is the sixth, says this: check to see if F. Reset Time and Auto Reboot are opted for and, if you selected the .pit file already, also check mark Repartition.
  7. Step seven needs the following from you: hit Start.
  8. Step eight will afterwards come with this task: when you see that the flashing of the UBAMC2 is done (that will happen when PASS will be on the screen and a green background will also appear), you have to disconnect the Duos GT-I9082L from your laptop.
