Most of the Samsung Galaxy S5 smartphone can now be rooted by using the CF-Auto-Root tool. Chainfire develops the CF-Auto-Root tool, and he has been developing these files for many Android versions now. Often they need updating to work on newer versions of Android, but Chainfire does a terrific job of making that happening.

It does not matter what tool you decide to use to become the root user on the Android operating system if all you want to do is install applications that need root access before they run. All of the tools grant the same amount of root access to the apps so there isn’t one app that will work and one that won’t work depending on the way you got the root access. However, there is a difference with customizing your mobile device in general and the way you go about getting root access.

A one-click rooting tool like the CF-Auto-Root tool gets root access without you need to do anything on the device. However, if you go the other route and decide to get root access by flashing the SuperSU manually, you can only get that done if you have installed a custom recovery image on the device first. Many people want to have a custom recovery like TWRP installed because they want to install new ROMs and new kernels and it is required before those things are possible. On the other hand, many people do not want those things and only want the root apps. That is how people make their decisions with what route they will decide to get root access with if there comes a time when you have the chance to choose between the two methods.


  • Chainfire was using the Samsung Galaxy S5 SM-G900MD smartphone running on the MMB29M.G900MDUBU1CPG1 firmware build number when he developed the version of the CF-Auto-Root tool that is available in this guide. It does not mean you need to be running that same firmware; that is not what he is suggesting when he hands over that information. You can just use it as an indicator when it becomes relevant information—if at all.
  • You can send Chainfire a message by using the CF-Auto-root tool thread at the XDA-Developers website of you are using the guide and the rooting file is not working. You know it is not working and needs updating if you use it and your smartphone does not boot after you flash the file.
  • The message that you send needs to contain the recovery image file from the firmware that is running on your phone because he uses that file to update the rooting file os that it starts working again.
  • You need to have the SM-G900MD model numbered variant of the Samsung Galaxy S5 smartphone to use this guide. If you try flashing the rooting file in this guide on any other model number it bricks the device and requires a new stock ROM to be flashed on the phone before it works again.
  • You need a computer that is running on a version of the WInwows operating system to follow this guide. Using another operating system will not run the Odin flashing application, and thus the flashing cannot happen.
