How to root Samsung Galaxy A8 on Android 5.1 [Guide]

Samsung Galaxy A8Rooting the Samsung Galaxy A8 smartphone would usually be done with a rooting tool like Chainfire’s CF-Root tool. However, it seems the KingRoot universal one-click rooting app is the exploit that managed to come up with a working rooting method first this time. Here’s how it’s done:


  • These are the guidelines to root Samsung Galaxy A8 smartphones running Android 5.1 Lollipop operating systems. You can check your OS by pointing to the Menu > Settings > About Device and looking at the Android OS version from the menu on your Samsung Galaxy A8 device. The Samsung Galaxy A8 smartphone is currently running Android 5.1 out of the box, and as such, you should check for a newer guide if you are running something else in the future.
  • The universal one-click rooting method we are showing you in this guide does work for many other devices; however, you should look for a unique guide that is made for your device for specific instructions.


  • Technically, these are these steps to root the Samsung Galaxy A8 smartphone without a PC, but we are showing you how to transfer the rooting file from the PC because it’s the safest method. You can skip that part and get the APK directly on your device if you do not have a PC or computer to use.
  • You need to have the Developer Option menu unlocked and the USB Debugging Mode enabled on your Samsung Galaxy A8 before you can get stuck into the guide. Furthermore, you’ll need to enable the Unknown Sources from the A8’s settings so you can accept applications from third-party sources that are also outside of the Google Play Store.
  • Unlocking the Developer Options: Menu > Settings > About Device > tap the build number seven times and it will let you know that you are now considered a developer.
  • Entering the Developer Options and enabling the USB Debugging Mode: Menu > Settings > Developer Options > Check the box for the USB Debugging Mode option.
  • Enabling the Unknown Sources: Menu > Settings > Security > check the box for  Unknown Sources.


  1. Download the KingRoot application directly to your computer and shift it over to the desktop.
    – it can be any computer; it does not have to be a Windows PC.
  2. Connect the Samsung Galaxy A8 to the computer and transfer the KingRoot app over to the root of the internal storage SD card.
    – make sure it’s the root of the SD card and not hidden in one of the potential sub folder, or else you might not find it later.
  3. Unplug your Samsung Galaxy A8 device from the computer.
  4. Launch any File Manager on your Sammy A8 handset and install the KingRoot APK so it transforms into app form and is available from your app drawer.
    – you can use any File manager for this job; download one from the Google Play Store if you don’t have one already.
  5. Once you have installed the KingRoot APK, open the app from the app drawer where you normally find your new applications.
    – you will get three new apps from your app drawer: KingUser, KingMaster and KingRoot — open the latter name.
  6. Tap on the large button that suggest rooting your device, usually with the words “Try To Root”.
  7. The KingRoot tool will now work its magic and root the Samsung Galaxy A8 smartphone. Wait until you get the success notification and the progress bar reaches 100% before you exit the same app on your device.
  8. Lastly, reboot the Samsung Galaxy A8 smartphone manually, the way you would normally reboot the device. Now you are ready to start installing your apps that require root access from sources online like App Brain and the Google Play Store.

You might also want to flash a custom recovery on the Samsung Galaxy A8 smartphone so you can completely customize your device properly and start flashing a new custom ROM when your Android OS becomes outdated.
