One of the most compelling parts of the mobile operating system is how applications have replaced everything. When we first heard about mobile devices that we could fit in our pockets, one of the biggest selling points was the gaming side of things and how all games were being played by using apps. However, the use of apps on our mobile operating system far extends past what we can do with games.

Apps on the mobile operating system are designed to do just about anything these days. You can find apps out there to help you balance your budget, let you know what the world times are, tell you when you should be feeding your baby and cooking dinner or even apps to tell you how good you look. The way the mobile operating systems are designed to today’s standard means that nobody needs to fiddle with coding to get things done like it would traditional need to be deal with from a computer and so forth.

Most of the apps that are out there on the Google Play Store and from other application stores can run on the device in your hands without you doing anything other than paying for them, but that is not always the case. There are thousands of other apps that you can download, but they will not run unless they can see that you have control of the root user account.

The root user account is to Linux what the admin account is for Windows and since the Android operating system is based on the Linux kernel that means people using Android refer to this maximum permission account as the root user account. That is what you are getting access to when you follow a guide like the one that we have here below.

Notes:

  • Chainfire tells us that he had the MMB29K.G550FYXXU1BPH1 firmware build number running on the Samsung Galaxy On5 SM-G550FY smartphone when he developed the version of the CF-Auto-Root tool that is available in this guide. You do not need that same firmware version running on your smartphone when you follow this guide. He gives that information so you can use it as an indicator but nothing more.
  • There is a proper CF-Auto-Root tool thread setup over at the XDA-Developers web forum that everyone can visit if they want to learn more about this rooting tool. Chainfire, the developer of the tool, also encourages people to leave the message on the thread if there is a device that they want a version of the CF-Auto-Root tool released for if there is not one available yet already. The same thread is also the place to leave a message regarding the current version of the CF-Auto-Root tool that is released already if one of them is not currently working. You know a file needs updating if you flashed it and the smartphone or tablet that you are using does not boot up afterward. That is a classic symptom of a new bootloader being in a newer version of Android. To solve that problem you need to leave the recovery image file in the message on the thread because he uses that to update the rooting file then so that it starts working again.
  • You need to have the Samsung Galaxy On5 phone that comes with the SM-G550FY model number if you are to follow this guide and flash the version of the rooting file that is available in this file. There are many different version of the CF-Auto-Root tool—each only available for the one model number. Not only that but flashing the working one often results in the bricking of the device and requires a stock ROM flashed on it to get it working again.
  • You do need to have a computer that runs on a version of the Windows operating system to complete the steps available in this guide. It does not matter what version of Windows as long as it is above Windows XP.

How to Root Samsung Galaxy on5 SM-g550fy on Android 6.0.1 (Marshmallow) Using CF-Auto-Root

  1. Unlock the Developer Options menu on the Samsung Galaxy On5 SM-G550FY smartphone so you can open it up and then use some of the options that are available to developers inside.
  2. Turn on the USB Debugging Mode from the Developer Options menu and then the Android software allows you to start making changes to it which are what you need if you are to root the device.
  3. Install the Samsung USB Drivers on the computer so that when you do connect the Samsung Galaxy On5 smartphone to the computer with the USB cable, it can get detected by the flashing app.
  4. Extract the rooting file in the Downloads folder and the flashing app and the flashable version of the rooting tool become available.
  5. Run the Odin flashing tool application by clicking on file available inside the Downloads folder.
  6. Boot the Samsung Galaxy On5 SM-G550FY smartphone into the Download Mode that it has and then connect it to the computer with the USB cable.
  7. Look out for the ID: COM port lighting up with a color from the Odin user interface and for it to show an added message there also which is there to tell you that your device is connected correctly and ready for the flashing because the Samsung USB Drivers are working correctly.
  8. Do not make any changes from the default options that you get from the Odin options tab.
  9. Click on the AP button and navigate to the Downloads folder where you extracted the file already and picked out the rooting file to upload to the Odin.
  10. When you can see the rooting file extension present from the Odin user, interface. Click on the Start button that Odin has, and the rooting of the Samsung Galaxy On5 smartphone begins.
  11. Check out the text that is now rolling down the display of the Galaxy On5 smartphone because Chainfire has cleverly programmed it to let you know everything that is happening as it is going on, so you always know what to expect. (That part is important because the process changes depending on the version of Android).
  12. Wait until the smartphone shows the message om the display that it is going to reboot in ten seconds.
  13. Check that Odin then shows a message stating that it passed inside a green box before unplugging the smartphone from the computer and the USB cable.

In conclusion, that is how to root the Samsung Galaxy On5 SM-G550FY smartphones running on the Android 6.0.1 Marshmallow software updates. The guide makes use of the systemless root version of the CF-Auto-Root tool that you might have heard about already. The SuperSU app is installed on the smartphone, and you see it available if you search through the apps as soon as the smartphone reboots back into the normal mode. You can open up the Google Play Store and start installing the root applications without having to adjust any of the settings available from inside the SuperSU app, but there are many options inside SuperSU that you can take a look at if you want to do that too.
