The Samsung Galaxy A8 smartphone can be rooted using the CF-Auto-Root tool by Chainfire. The developer, Chainfire, has made a CF-Auto-Toot tool for hundreds of smartphones and tablets from the Samsung range. While the files themselves change for the rooting method, what you can do after the rooting procedure is always largely the same: install apps, custom recoveries, kernels, mods, ROMs and so forth. Apps is generally the main attraction unless you want to install a custom recovery along with having your internal system unchained with the root access.

One root application we suggest people check out is the Dumpster app. With the Dumpster app running on your Samsung Galaxy A8 smartphone, it’s easy to restore old pictures you once deleted. Furthermore, you can restore old video files and music files too. Dumpster is one of the hottest rooted apps for Android coming into 2016 and should continue to be atop many people’s lists.

Files You Need

  1. Download the CF-Auto-Root file for the Galaxy A8 SM-A800 running Android 5.1.1 from here.
  2. Chainfire gives us the LMY47X.A8000ZCU2AOK6 build number of the firmware along with the file so we can use it as an indicator. You do not need to flash that same firmware on your Galaxy A8 device before rooting. It will work on any firmware build ID so long as you are running Android 5.1.1 Lollipop.
  3. You can check the Android version of your software on the Samsung Galaxy A8 smartphone by tapping on the Settings > About Device > Android Version.
  4. You must have the SM-A8000 model number to use this guide. You can find out the model number of your Galaxy A8 smartphone by tapping on the Settings > About Device > Model Number.

Rooting the Samsung Galaxy A8 SM-A800 running Android 5.1.1 Lollipop

  1. Enable the USB Debugging Mode on the Samsung Galaxy A8 device before you try connecting to the computer.
  2. Extract the CF-Auto-Root for the A8 to the desktop of the computer and you will get the rooting file and the flashing tool file.
  3. Right-click on the Odin flashing tool executable file and choose to run it as an administrator.
  4. Do not change any of the default settings from the Odin flashing tool’s user-interface when the app eventually opens on the desktop of the computer.
  5. Boot the Samsung Galaxy S8 smartphone to download mode and then connect to the computer with the USB cable.
  6. Wait for a minute and you should see the blue to yellow ID: COM port light up from the Odin application. No light there means you need to install the drivers. You can do it by installing the universal Windows ADB driver.
  7. Click the AP button and then browse the desktop for the A8’s tar.md5 rooting file that you extracted there earlier.
  8. Click the Start button and then wait until the rooting file is flashed on your device.
  9. Keep waiting until you see the pass message show up and the box turns green.
  10. Now turn your attention to the Samsung Galaxy A8’s display for when it says it is restoring the stock recovery, cleaning up and going to reboot in 10 seconds.

The Samsung Galaxy A8 smartphone will now reboot to recovery mode and the rooting will be complete. The A8 device must get to recovery mode or it will not have worked. You can use the hardware buttons and boot to the recovery mode manually if you need to do that when the flashing stops.
