Rooting the Samsung Galaxy S Duos smartphone is going to be just as advantageous as it was when you rooted any of the other devices from the Samsung range. Often the rooting process itself can be confusing because the way we root our devices various depending on what the device is. That is where the confusion ends though and as soon as your device is rooted everything else is the same. You can install all the same apps from the Google Play Store like the Titanium Backup app to remove or freeze your system apps; you can head to the XDA-Developers website to check out what custom ROMs are up for grabs for your device and so forth.

As far as root apps go on the Samsung operating system, we usually recommend the Titanium Backup app. The application probably deserves a new name because much of what people like it for isn’t for the backing up at all but rather the uncanny ability to freeze or uninstall apps. It has its annoyances — you cannot free an app unless you get the paid version, so it forces you into taking huge risks in potentially uninstalling the wrong app which you could ill afford to do, and now your phone is bricked. However, the upsides are enormous once you have put in the time to do your research and you have uninstalled or frozen the right apps. That is where you have to decide whether it is worth paying the small fee for the paid version or not. The time you spend researching what you can delete can often far exceed the money you would have earned if you were working a job for that same amount of time. As so often is the case, there is a good reason for installing the paid version if you think about it. That is the business is set up to thrive. So even though it is annoying to have to pay for something, it allows the developer of the Titanium Backup app to make some money from his excellent work, all while allowing people to freeze apps without any research, learn whether it affected the operating system and then choose to unfreeze it or keep it frozen. Once you have frozen all of the apps you do not need, you will find the performance on your Samsung Galaxy S Duos smartphone is significantly increased.

Files You Need

  • Download the rooting file for the S Duos GT-S7582 from here.
  • Download the Samsung USB Drivers from here.

You must have the GT-S7582 model number of the Galaxy S Duos smartphone for this guide to work or else the rooting script will probably brick the handset according to the developer.

Any Samsung smartphone with Knox security will get that protection tripped when rooting with the CF-Auto-Root tool.

There will be some Android software updates that roll out for the Samsung Galaxy S Duos smartphone that can bring new bootloaders with them. The new bootloaders present a problem for people like Chainfire — who is the developer of the CF-Auto-Root tool we are using –, and that is it will stop working until he updates the file, so it works with the new bootloader. For him to be able to apply the changes, he relies on the readers using his tools like you guys to submit the new recovery image file found inside the new firmware update to the official CF-Auto-Root tool thread found over at the XDA-Developers website. Once he sees your message, he will apply the update and the file will start working again for everyone that tries to root. In the meantime, the files that need updating will cause devices not to flash or not boot. That is why sometimes you see people saying their device no longer turns on after trying to root the device. These occasions are rare, but they can happen. Note that these issues with the smartphone not turning on are not permanent.
Android 4.2 Jelly Bean

Rooting the Samsung Galaxy S Duos 2 GT-S7582 running on the Android 4.2 updates

  1. Unlock the Developer Options menu on the Samsung Galaxy S Duos smartphone so you can turn on the USB Debugging.
  2. Enable the USB Debugging Mode on the Galaxy S Duos smartphone so you can use apps on the computer with your device connected.
  3. Extract the CF-Auto-Root file to the desktop of the computer.
  4. Run the Samsung USB Drivers on the Windows computer before you proceed to the next step.
  5. Double-click the Odin flashing app and wait for the user interface to open on the desktop.
  6. Boot the Samsung Galaxy S Duos smartphone into the download mode and connect it to the computer with the USB cable.
  7. Wait for a few seconds and you will need to see a yellow or blue color coming from the ID: COM port before you can continue. (That color coming from the ID: COM means your Samsung Galaxy S Duos smartphone is added, and the drivers are working.)
  8. Click Odin’s AP button from the Odin user interface and upload the rooting file ending in the tar.md5 file extension that is on the desktop.
  9. Do not make any changes to the default settings that you get from the Odin user interface.
  10. Click Odin’s Start button from the desktop of the computer and the rooting will begin.
  11. Check the screen of your S Duos and wait until you see that it says it is installing the SuperSU, cleaning up the cache partition and then reflashing the stock recovery.
  12. Look up at the computer screen now and check that you get a green box lighting up with a pass message inside.

In conclusion, the Samsung Galaxy S Duos smartphone should now be rooted on the Android 4.2 Jelly Bean update. Those of you are wanting to try running Android 4.4. KitKat can do so by installing some of the custom ROMs that are available for this smartphone. You will find some of those ROMs by using our search box or by heading over to the XDA-Developers website — the home of custom ROMs.

You can quickly check that everything on the Samsung Galaxy Note 3 smartphone is rooted and well as intended by heading to the Google Play Store application and installing the root checker app. You will find that the root checker app comes in a free version and a paid version, but it is only the free version that you need to check whether your smartphone is rooted or not. The paid version will unlock some bonus features if you want to use them later.

Once you have installed the root checker app and check that your device is rooted, you can start installing your root requiring applications from the Google Play Store and other third-party sources online. Anyone, who does not have a rooted Galaxy Note 3 as this time, can think about checking the following things.

Firstly, you ought to check that your smartphone is getting into the required recovery mode once the flashing completes. Any smartphone that doesn’t automatically go into the recovery mode will not be rooted. You can fix that by booting into the recovery mode manually by pressing the hardware button combination for that mode as soon as the flashing completes of the CF-Auto-Root tool.

Moreover, those still stuck can try installing another version of Samsung’s Odin app. The Odin flashing tool comes in at last five versions that can be installed, each with a unique version number. Chainfire gives us one version bundled in with the rooting file but sometimes a version can randomly not work for a device which means the person needs to install another version. You can find all versions of the Odin flashing application from the Odin downloads page on our website.
