The Samsung Galaxy A3 is the bottom of the range of the A-Series from Sammy during 2014, but just because it’s the cheaper variant doesn’t mean there aren’t numerous third-party developers creating awesome custom ROMS and other compatible tweaks. You can also check out root-requiring applications from the Google Play store and other sources which enable you to take away the annoying bloatware from Samsung. Furthermore, you can tweak the OS by overclocking and equip yourself with other useful apps to brighten your day.

Making all of the above happen for your A3 smartphone is easy. Just follow the guide after the jump:


  • You can only follow the directions below if you have the A300H variant of the Samsung Galaxy A3 smartphone. Check the model number of yours by stopping over at the Settings > About Device and taking a gander.
  • Just like the specific device number,m you also need to be running the specific firmware. The latest software update rolling out for the A300H variant of the A3 is XXU1AOA4 Android 4.4.4. You can also check your device runs the same by taking a look under the About Device section from the Settings.


  • Make sure you have enough battery power left on your smartphone before starting the flashing so that it doesn’t turn off before the guide is finished. You could soft brick the phone if it doesn’t make it all the way. We recommend starting the guide with at least 60% battery power. Check that by turning on the phone and looking at the battery icon from the Status bar.
  • Understand that following on from here does void the A3 warranty. You can get the warranty working again which allows you to send the device away for free repairs by unrooting it. Do that by installing third-party dedicated applications from the Google play store.
  • You must have a Windows PC for the guide because Odin is an official tool by the Samsung developers which only works with the Windows operating system.


1. Download the CF Auto Root package from here.

2. Download the Odin 3.09 from here.

3. Use the desktop of the computer for both downloads.

4. Extract both folders and run the Odin app on the computer.

5. Reboot the A3 in Download Mode.

6. Press the Volume Down, Home and Power buttons simultaneously to do that.

7. Now press the Home button one more time at the new warning screen.

8. Once in download mode, connect the phone to the computer with the dedicated USB cable.

9. Click the AP button and upload the tar.md5 file extension from the rooting file you extracted.

10. Click the start button without adjusting any of the other settings.

11. The tool will now continue to flash the device with root access.

12. Wait until you see the device reboot. The Odin application does that automatically since we had the Auto reboot checkbox ticked.

You are now running with root access on your Samsung Galaxy A3. It’s time to check out those root apps and custom ROMs and have some fun. You can expect to find most of those root applications from the same Google Play Store application that you already have on your device and that you use to download your regular apps. There’s also a Google Play STore web link you can find from any web browser when you use Google, but you might as well use the preinstalled application that comes with Android when you’re browsing from your smartphones.

Some root applications allow you to install custom ROMs such as the ROM Manager app, but you might need to have an unlocked bootloader first before you can get them running. Read the requirements from the custom ROM sources for further information on how to proceed with them. Otherwise, there are no restrictions on what you can do with any of the other root applications. They all work no matter what tool you used to get the root access. That said, some of them have a free version which is basic and has some features, and then there’s a paid version that unlocks more features. The Titanium Backup app is one of the best root apps out there, and you might want to think about investing in the paid version if you install it because it can save you a lot of money in the long run. The paid version unlocks features that allow you to rewind the clock on your operating system if something goes wrong whereas the free version will make you live with your mistakes.
