Buying a smartphone like the Samsung Galaxy A8 phone is going to mean you run Android. Android is always a great mobile operating system, and for many people, it is the only mobile operating system worth using.

There are discrepancies between a desktop operating system and a mobile operating system, and that mainly is apps are used a lot more on mobile devices than desktop. Many people don’t know this, but desktop operating systems use apps too. All of the programs you are using are called apps. However, there are millions of apps available for mobile devices and nothing close to that number being used from a desktop environment.

Regardless of the operating system, the thing you need to be careful of is malware and a virus when you are using it. Sometimes that means not clicking on things from websites and other times it means not installing certain apps. As you can guess, the threat of the malware from a mobile operating system is much greater since there are many more apps being used and more apps containing malware. That is one of the reasons the mobile operating systems come locked. The locked mobile operating systems mean that installing malware doesn’t do much harm because the malware cannot leave it’s app area where malware on rooted devices can wander around.

That isn’t the only reason why companies like to lock mobile operating systems. They also do it, so you are locked into using the apps that they want you to use. That kind of exploitation has lead to operating systems giving you the chance to toggle off many of the system apps that used to be forced upon you. While that additional options to toggle them off is great, it doesn’t allow for their complete uninstallation, and they are still using up the memory on the device that could be used elsewhere if you uninstalled them entirely.


  • Chainfire had the MMB29K.A800IXXU2BPG7 firmware build number running on the Samsung Galaxy A8 SM-A800I smartphone when he created the rooting file that you are using in this guide. He just gives the information of the firmware build number he used so you can then use it as an indicator in the future. It does not mean you need to flash that firmware on your device before rooting.
  • The CF-Auto-Root tool is only flashable on the Windows operating system, so you need to have a version of the Windows OS to follow this guide.
  • You need to have the Samsung Galaxy A8 smartphone that comes with the SM-A800I model number to use this guide. The CF-Auto-Root tool comes in many different versions, and they are usually for each model number. Moreover, flashing the wrong version of the wrong model number means that device is typically bricked until you flash the stock ROM on it again.
  • You need to let Chainfire know if the CF-Auto-Root tool is causing your device not to boot up after flashing the file or if the flashing does not work as these are typically issues that arise when the new bootloader has stopped the rooting tool from working. Leave a message on the CF-Auto-Root tool thread from the XDA-Developers forum that is made for the tool by Chainfire that contains the recovery image file on it. He needs the recovery image file from the firmware you are running that is creating the problem before he can make the necessary changes to the rooting file. Once he updates the file on his end, it starts working again on our guides because we link directly to the source.

How to Root Samsung Galaxy A8 SM-A800I on Android 6.0.1 Marshmallow Using CF-Auto-Root

  1. Turn on the Windows PC and log into the administrator’s account, so you are using the Odin flashing tool run as the Admin. (Alternatively, you can sometimes right-click on the Odin application and choose to run it as the administrator if you cannot get admin access to the PC itself).
  2. Unlock the Developer Options menu that the Android software on the Samsung Galaxy A8 SM-A800I has available so you can start making changes to the options that are available for developers to use.
  3. Turn on the USB Debugging Mode from the Samsung Galaxy A8 SM-A800I Android software’s Developer Options menu that you just turned on, so the Android operating system then allows you to make changes to it.
  4. Install the Samsung USB Drivers on the computer so the Odin flashing application can detect the type of mobile device you want to connect with it.
  5. Open up the Downloads folder on the Windows PC and then extract the rooting file to the same Downloads folder and then click on the Odin flashing application so that it runs and the user interface of the flashing tool is open on the computer.
  6. Boot the Samsung Galaxy A8 SM-A800I smartphone into the Download Mode that it comes with and connect it to the computer with its USB cable.
  7. Check Odin then shows you a color from the ID: COM port box and the added message is showing up from the log, so you know that the Samsung Galaxy A8 smartphone is connected correctly because the Samsung USB Drivers are working.
  8. Do not change any of the default settings that are available from the Odin Options tab.
  9. Click on the AP button from Odin and then navigate to the same Downloads folder on the computer that you extracted the rooting file before and then click on it so that it uploads to the Odin application.
  10. Click on the Start button from Odin and the rooting of the Samsung Galaxy A8 smartphone begins.
  11. Check the information that is rolling down the display of the smartphone programmed by Chainfire to fill you in on everything that is happening and what to expect in this particular version of the rooting tool over the next few minutes.
  12. Check that Odin shows a green pass message from its user interface once the Galaxy A8 smartphone has rebooted.

Now you know that the Samsung Galaxy A8 SM-A800I smartphone is rooted running on the Android 6.0.1 Marshmallow software updates by flashing the one-click rooting tool called CF-Auto-Root. The rooting tool has just used a new recovery and cache to install and enable the SuperSU program on the smartphone, and you can see it as an application on the smartphone when you start using the phone. You can open up the app and check out what settings the SuperSU has to offer if you want but none of the settings need changing before you start running the root applications you have been waiting to try.

You can open up the Google Play Store and install one more app called the root checker app if you prefer checking whether or not the device as root access before getting stuck into installing the root applications. That way if something doesn’t run on the root app you know it isn’t anything to do with the rooting tool or not having the root access. All of the root apps should run once the root access is confirmed.
