Rooting the Samsung Galaxy A3 smartphone results in you getting more application choices from the Google Play Store. You may also find APKs you can install from other third-party developer pages. Some of the apps we recommend you install include the Tasker app for total automation control of your device; the ROM Toolbox for all your ROM needs coming from the one source; the SetCPU for Root users app so you can tweak the performance of your device and the DiskDigger app so you can find those files you accidentally deleted. Of course, they only represent a few of the best ideas for you to install, but there are many more apps worth installing.

Rooting the Samsung Galaxy A3 4G Duos

  1. Download the rooting package to your Windows computer. It will end up in the Downloads folder by default unless you have changed the default download location.
  2. Open the Downloads folder and find the file. Now click and drag the file over to the desktop of the computer.
  3. Right-click over the file and choose the “extract here” option.
  4. Do the same thing with the Odin package so it’s extracted on the desktop.
  5. Run the Samsung USB Drivers on your computer so they are installed.
  6. Double-click the executable Odin file that’s on your desktop and wait for the Odin user-interface to open.
  7. Turn off the Samsung Galaxy A3 device and reboot it in download mode.
    – reboot by holding the Volume Down + Home + Power to get the device in download mode.
  8. Connect the Samsung Galaxy A3 device to the computer using the USB cable.
  9. Wait for the ID: COM port to change colors so you know your drivers are working. If the color changes in the ID: COM port, you should try a different Odin version if it doesn’t flash the rooting exploit to your device.

  11. Click the Start button available from the Odin user-interface and the Odin flashing tool will now flash your device with that same root exploit.
