How to root Samsung Galaxy A9 Pro SM-A9100 on Android 6.0.1 with CF-Auto-Root [Guide]

samsung-galaxy-a9-proRooting the Android OS that runs on the Samsung Galaxy A9 Pro smartphone is the way to get the opportunity to install any of the apps that are out there available for your device. The device you are given comes with a locked operating system that many people never notice the difference, but a lot of people do. The difference is that there are many apps available from Google Play and other sources online that will download and install but when you try to open them without a rooted device, they will not run. These are what we call root apps, and they are what you can run when you complete the guide after the break.


  • You need to have the Samsung Galaxy A9 Pro smartphone that comes with the SM-A9100 model number to use this guide. Flashing the incorrect version of the CF-Auto-Root tool can brick your device, so make sure you check you have the right one. You can find out the model number of the Samsung Galaxy A9 Pro smartphone by tapping on the Settings app > About Device.
  • You need to have a computer that runs on a version of the Windows operating system to use the Odin flashing tool file available in this guide.


  • Install the Samsung USB Drivers on the computer before you get started with the steps of the rooting procedure so that your smartphone can be detected by the flashing tool.
  • Unlock the Developer Options menu on the Samsung Galaxy A9 Pro smartphone and then enable the USB Debugging Mode so you can make changes to the Android software.
  • Note that Chainfire often makes the firmware build number that his version of the device was running when he developed the rooting file available in our guides, but that doesn’t mean you need to be running the same firmware build numbers as him. He just gives you that information if you want to use it as an indicator. The version, in this case, is the MMB29M.A9100ZCU1APF1 firmware build number. You can run any version of the Android 6.0.1 Marshmallow software updates regardless of the firmware build number as long as you have the right SM-A9100 model number.


  1. Download the CF-Auto-Root tool for the Samsung Galaxy A9 Pro SM-A9100 smartphone running on the Android 6.0.1 Marshmallow software updates.
  2. Extract the rooting package to the Downloads folder on the computer to find the flashing app and the flashable rooting file available.
  3. Boot the Samsung Galaxy A9 Pro SM-A9100 smartphone into the Download Mode before connecting it to the computer via the USB cable.
  4. Run the Odin flashing app that is inside the Downloads folder, so the flashing user interface opens.
  5. Check that Odin gives a blue or yellow ID: COM port and an added message from the Log that are both there to let you know that the Samsung USB Drivers are working, and your Samsung Galaxy A9 Pro smartphone is connected correctly.
  6. Click on the Start button and the Galaxy A9 Pro begins to get rooted with the CF-Auto-Root tool.
  7. Wait until a green box with a pass message inside it appears in Odin before unplugging from the computer.

In conclusion, that is how to root Samsung Galaxy A9 Pro SM-A9100 smartphones running on the Android 6.0.1 Marshmallow software updates by flashing Chainfire’s out-of-this-world one-click rooting tool, namely CF-Auto-Root.

    Hi there Abushke,

    It sounds like you might have a new device. That’s nice — always a good feeling.

    You don’t need to root your phone to do what you want to do. The Google Play Store and Snapchat are available for all Android users. Rooting is more for advanced users who are looking to do developing-related stuff.

    To get Snapshot installed on your A9 phone just turn it on > tap on the Apps button > Scroll until you see an app called “Play Store”> Search for “Snapchat” inside the Play Store > Click the button to Download it.

    Hope that helps.
