According to Google's rules, Android smartphone manufacturers must support their devices for at least a year and a half, that is, provide various minor updates, and most importantly, operating system updates. However, when the first year and a half ends, support for the device itself ends. What to do in this case? There is only one answer - to reflash the device. We’ll talk about how to reflash the Samsung Galaxy Grand Duos (I9082).
Be sure to remember this!
When you reflash your smartphone, carefully follow all the steps of the firmware that will be given below. Do not rush under any circumstances, this may end badly for your smartphone (you can get more information on this by following this link). The smartphone must be 100% charged until you charge it and start the flashing process. During flashing, all data on the SD card may be completely deleted, so take this into account and save all the files you need. Additionally, be sure to check the condition of your USB cord to ensure it is not damaged. Also, try to ensure that no one has access to the smartphone during the firmware process, since if the firmware process is interrupted, there is a high probability that your smartphone will turn into a brick, which will be completely useless. And don’t forget - your smartphone must have root rights. You can find out how to obtain these rights by following this link.

The Samsung duos gt-i9082 device arrived for firmware on a more recent android version 6.0, since the old 4.2 froze, I tinkered with it a little, it was clear that first it was necessary to install a custom recovery, but there were minor problems with it, after installing the custom recovery of the device it still booted in standard mode, then we’ll look at how to install custom recovery and flash it.
1. Install custom recovery
To do this, we will need the program One - (Odin), a custom recovery itself, in this example we use recovery TWRP-2.8.6.0, drivers for the phone, a cord to the phone, a fix for those who download a standard recovery after the firmware and direct hands.
And so let's go, install the drivers on the phone (So that the phone is detected in the Odin program), then download the Odin program.

In the warning that appears, press the volume + button. We entered the firmware mode, connect the cable to the phone. In the running Odin program it should be detected; if it is not detected, it means your drivers are crooked or you haven’t installed them! If everything is fine, we move on. In the Odin program, click on the PDA button and select the archive from the recovery, uncheck Auto reboot and click on the old button, and wait for completion. The next step is to install the fix about which I wrote above, press the volume up button + menu + power button after the word Samsung galaxy duos appears, release the power button, get into recovery, select install and open the fix file, which we first drop into the memory of the phone or flash drive, move the slider and We are waiting for completion, the installation of the recovery is complete!
We reboot just in case. Now to enter recovery you need to press the volume up button + menu + power button.

Now go into recovery and select install. Open our SD card and select the firmware, then move the slider for the firmware, wait for it to finish, go back to the main menu and do wipes and factor resets, after which we also go to install and select our archive with gaps, move the slider, after which you can reboot The device is ready for use, the first switching on is about 5 minutes.
