The Galaxy A3 2017 recently received the Android Oreo update. If you applied this official firmware then it means that you are now experiencing the stock / default Android UI along with the regular built-in apps and restrictions. That’s happening because when a new update is flashed the system is restored back to its factory state – basically, the recently applied tweaks are revoked. Thus, if you used to enjoy a rooted Android OS, now you have to reconsider the root access since the Android Oreo firmware is once more locked and pe-loaded with Samsung’s bloatware and restrictions.

What we’re trying to say is that you must re-root your Samsung Galaxy A3 2017 after setting up the Android Oreo software. Unfortunately, the root solution that used to work for the Nougat system is no longer compatible with the Oreo platform, so you need to follow another root method that can succesfully unlock the Android 8.0 firmware. Well, in that respect we are here to assist you.

Yes, that’s right; during this step by step guide we will see how the new Android Oreo OS can be rooted on the Samsung Galaxy A3 2017. As usual, before detailing the actual root steps we will discuss about essential pre-requisites, about risks and about the advantages that are related with this procedure, so do check all the lines from below before deciding to perform the unlock process.

As you might already know with root ensured you can enjoy an unlocked Android UI that can be further customized and optimized. That’s why, once you complete this tutorial, you can choose to tweak your Samsung Galaxy A3 in order to upgrade general performace, improve battery life and obtain better results when using your smartphone on a daily basis. Shortly, with root enabled you can unleash the true potential of your Android Oreo powered handset.

However, removing factory restrictions and unlocking the Andorid system aren’t operations supported by your OEM. Thus, Samsung KNOX will get tripped during the following steps, meaning that you can lose access to built-in apps and the warranty flag. Hint: if needed you can restore the warranty by reinstalling the stock Android OS via Odin.

As you will see below, for being able to gain root access you will have to use a custom recovery image. So, this tutorial will also teach you how to set up TWRP recovery on your Galaxy A3. Of course, if a custom recovery image is already running on your phone, skip that section and head towards the root steps.

But, before doing that consider in backing up your Samsung Galaxy A3 2017. It’s important to secure everything that wasn’t there by default as otherwise you can end up in losing personal data, info, accounts and files. As always, do the backup by using Samsung’s cloud storage platforms, by syncing your files with your Google Account or by downloading already tested backup and restore apps that are available (for free) on Google Play.

A computer running on Windows is required (for both the custom recovery and root procedures) and your smartphone and its USB cable must be there too. On your computer the Galaxy A3 drivers must be set up – the drivers can be installed automatically if you use the Samsung KIES toolkit.

On your smartphone enable Developer Options: navigate to About Phone and tap repeatedly on Built Number; after 7 or 10 repeated taps you will notice the ‘you are a developer’ prompt. Then, from Developer Options (you can access this field from general Settings) you have to check the USB Debugging feature.

Also, make sure you ensure more than 50% power on your handset before doing anything else. When the power is low a sudden shut down can happen while you complete the steps from below. Then, malfunctions can be caused and you can easily end up in soft-bricking your Samsung Galaxy A3 2017.

  2. Place those files on desktop and in the meantime power off your Galaxy A3.
  3. Next, reboot your Android device into recovery mode – press and hold the Power, Volume Up and Home buttons at the same time.
  4. Make a hard reset and choose to clear app data cache from recovery mode menu – pick ‘wipe data factory reset’ followed by ‘wipe cache partition’ and by ‘wipe dalvik cache’.

  6. Use your phone’s USB cable and connect your device with your computer.
  7. On your Galaxy A3 transfer the downloaded files that are now saved on desktop.
  8. When done, unplug the USB cable and reboot into TWRP recovery again.
