If you were to want to get root access on the Samsung Galaxy S5 smartphone the traditional way you would do it by getting a custom recovery image installed and then flashing the SuperSU program from that custom recovery partition which is the perfect platform for being able to enable the SuperSU on the smartphone so that it does grant the necessary rooting permissions to the apps that you install after you download them from sources online such as the official developer website or the Google Play Store.

The traditional method of becoming the root user is perfect for anyone who wants to get custom ROMs or custom kernels installed but isn’t so great for everyone else. Don’t get me wrong; there is nothing wrong with installing a custom recovery for the sole purposes of flashing the SuperSU. However, most people who do not need a custom recovery installed for other uses such as installing custom ROM elect to use the stock recovery partition instead.

If you are like them and would prefer keeping the stock recovery instead of swapping it over for a custom version, then you need to look for other ways to get root access. The most obvious choice is by using a one-click rooting tool—there are several of these available for any given device and offer a quick solution to getting control of the root user account.


  • Chainfire does show some information along with the rooting file from the repository page. In this instance, he lets us know that he had the MMB29M.G900FDXXU1CPF4 firmware build number running on his version of the Samsung Galaxy S5 SM-G900FD smartphone. He is not suggesting you need to go and find the same stock ROM that he had running when you follow this guide. He is just showing the firmware he had running so you can use it as an indicator. For the most part, it should not matter what firmware you have running; just make sure that it is running on the Android 6.0.1 Marshmallow.
  • You can visit the XDA-Developer web forum and browse the CF-Auto-root tool page if you want to get more information about the rooting tool. The thread also allows you to get in contact with the developer because he sees the messages that people leave in the comments. He requests that people let him know when one of the rooting files needs updating; you know one needs updating if you flash it and the smartphone or tablet does not flash afterward. Before he can fix it, he needs you guys to leave the messages on the thread that contains the recovery image file. He uses that file to update the rooting file so that it starts working again.
  • You need the Samsung Galaxy S5 smartphone that comes with the SM-G900FD model number if you are going to flash the version of the rooting file that is available in this guide. If you try flashing this rooting file on any other model numbered version of the Samsung Galaxy S5 smartphone, it will likely brick the device, and you will need to flash the right version of the stock ROM to get it working again. The stock ROMs are usually found over at the Sam Mobile website by clicking on the Firmware tab and then entering the model number of your device.
  • You need to have a computer that is running on any of the Windows operating system version to complete this guide. The Odin flashing tool that is going to flash the rooting file only runs on Windows operating systems.
