The CF-Auto-Root tool is what you are going to be using in the guide below to root the Samsung Galaxy S7 SM-G930V smartphone. The man behind the CF-Auto-Root tool is the same guy who makes SuperSU. That makes sense since you will find SuperSU installed on your smartphone after you finish flashing the CF-Auto-Root rooting tool.

There isn’t anything that you need to do after you have flashed the rooting tool before you can start using the applications that require root access before they can run. All of them can be downloaded, installed, and run as soon as the guide is complete. Nonetheless, it is possible to manage the SuperSU permissions so you can change things from the default settings.

The SuperSU app is on your device as soon as you reboot it. You’ll see it there in the app drawer along with any of your other apps that you might have previously installed. The older versions of SuperSU used to look more like a Superman symbol with the hash (#) symbol in the middle. The newer additions of the SuperSU app icon is just the hash symbol by itself with a green background. If you still don’t think you can identify it, you can always open the Google Play Store and check out the SuperSU application that is available to download from there. It’s no use installing that version of SuperSU and expecting root access because that’s not how it works, but it’s useful to understand what the logo looks like if nothing else.

The SuperSU controls which apps get root permissions. By default, you have to manually grant apps root access before they will run—even when you have SuperSU installed already. It has to be that way for security reasons (you don’t want to give things root access unless they are trusted automatically.) You need to make sure you know what you are granting root access before you hand over the reigns to an app because SuperSU isn’t anti-virus (it doesn’t stop you from installing bad things.) Its job is just to stop everything in its wake and then leave it up to you what goes through the gates.

Details We Should Know

  • The Android 7.0 software update with build number NRD90M.G930VVRU4BQC5 was running on Chainfire’s Samsung Galaxy S7 SM-G930V smartphone when he created the rooting method available in this guide. However, that does not mean you need to be running the same software update. Chainfire states that it should work on any firmware build number for the Android 7.0 Nougat software update.
  • If you flash the CF-Auto-Root tool using Odin on the Samsung Galaxy S7 SM-G930V smartphone and it causes the device not to boot up, don’t stress. The smartphone is not bricked permanently; it just needs firmware flashed on it manually using the Odin flashing tool. You need to let Chainfire know about the problem by leaving a message on the CF-Auto-Root tool thread so he can update the file, so it starts working again.
  • You need to have the Samsung Galaxy S7 smartphone that comes with the SM-G930V model number to use this guide. Flashing the wrong CF-Auto-Root file for your model number does not work, and you need to flash the firmware with Odin to get the device working again.
  • All versions of the CF-Auto-Root tool need to be flashed with Odin. The Odin flashing tool needs to be used on the Windows operating system.

Files We Need

  • Download the CF-Auto-Root tool for the Samsung Galaxy S7 SM-G930V running on the Android 7.0 Nougat software updates.
  • Download the Samsung USB Drivers for the Windows operating system running on your computer.

How to Root Samsung Galaxy S7 SM-G930V on Android 7.0

  1. Log in to the computer running on a version of the Windows operating system using the administrator account.
  2. Unlock the Android Developer Options menu on the Samsung Galaxy S7 SM-G930V smartphone so you can turn on the USB Debugging.
  3. Enable the USB Debugging Mode on the Samsung Galaxy S7 SM-G930W8 smartphone so that the Odin flashing tool can make changes to the operating system when flashing the rooting files.
  4. Install the Samsung USB Drivers on the Windows operating system so that Odin can detect your device when you connect it to the computer.
  5. Extract the CF-Auto-Root tool to the Downloads folder on the computer and then double-click on the Odin executable file from the Downloads folder.
  6. Boot the Samsung Galaxy S7 SM-G930V smartphone into the Download Mode and then connect it to the computer with the USB cable.
  7. Wait for the ID: COM port to light up blue or yellow and give an “added” message. If you do not see that, then the USB Drivers are not installed correctly on the computer yet.
  8. Do not make any changes to the default Odin settings from either of its tabs on the Odin user interface.
  9. Click on the AP button and then navigate through to the Downloads folder and select the rooting MD5 file to upload to the Odin.
  10. Click on the Start button from the Odin user interface and then wait for the rooting of the Samsung Galaxy S7 SM-G930V smartphone to complete.
  11. While the smartphone is being rooted, have a read of the information that is running down the display of the device, so you know what to expect.
  12. When complete, the Odin user interface shows a pass message in a new green box.

The Samsung Galaxy S7 smartphone will reboot by itself, and the SuperSU is then available from the app drawer. You can install one of the root checker apps that is available from the Google Play Store to check if the root access worked. Alternatively, you can begin installing the root apps and see if they are working. For example, if you install the Titanium Backup app on your device and open it up, there will be a new message on the phone’s display asking if you would like to grant the Titanium Backup app root access. As soon as you click on the “Grant” button, the root access is applied to the app so it can start functioning. If you think you have made a mistake and granted the root permissions to something you wish you shouldn’t have, it is possible to undo your decision by going inside the SuperSU app and managing the permissions.
