Back in the day when Android was still a new operating system, you had to root the device to do simple things like adjust the LED light or take a screenshot. Nowadays those days are thankfully over, and features like those are built into the standard operating system you get stock with the device. There is still an abundance of reasons to root your Android device these days, though, and many of those reasons aren’t likely to be coming stock in your operating system anytime soon. One of those reasons we assume will always be to run something like the Ad Away app. Now we dislike those apps that block ads because they take away our earnings, and we can safely assume Google doesn’t want them coming natively in the operating system they own, nor will they want the app available from the Google Play Store. You will find many reasons like that where it doesn’t make much sense to give the features of a stock Android environment either because Google doesn’t want them or giving regular users that much power might never make sense or be safe.

Chainfire bases the rooting method for the Samsung Galaxy S5 Duos smartphone on the LRX21T.G900MDUBU1BOH4 firmware. Chainfire says that the gives us the firmware build ID that he bases the rooting process from so we can use it as an indicator because some of the Samsung smartphones and tablets will not boot older images. However, he also states that it does not mean you need to be running that same firmware on your device before rooting. As long as you have the SM-G900MD model number, and it is running the Android 5.0 Lollipop software updates then this guide should work for your device.

  • The CF-Auto-Root tool developed by Chainfire has its original XDA-Developers thread where people can report any issues. The main issue that arises with this rooting method is that new software updates can sometimes bring new bootloader which can cause a device not to flash or not boot after using the CF-Auto-Root tool. Chainfire asks people to let him know which device that is happening for and for you also to leave the new recovery image that came with that firmware so he can fix the problem.

Anyone not finding the smartphone working might want to try installing one of the other versions of the Odin flashing tool that is available to install and start again. It comes in a few versions, and the version we have given in the guide is the latest version. It should work for nearly everybody, but there are reports of people having to try a few versions before one of them finally worked. Moreover, anyone who still doesn’t find the Samsung Galaxy S5 Duos smartphone rooted should try checking whether the smartphone is making it into recovery mode or not. Chainfire, the developer of the CF-Auto-Root tool, states that if a device does not get into the recovery mode after the flashing that it will not have installed the SuperSU correctly, and it will not be rooted. All you need to do is manually hold the hardware button combination for the recovery mode and boot into the recovery mode that way after the flashing, and it should be rooted.
