Samsung Galaxy S5 has a dual SIM version called the Duos variant of the phone. Since the mechanism in the Duos variant is a bit different than the original variant, the root procedure is different than what it is for the original Galaxy S5. The different is just in the files that you use to root the phone while the whole procedure remains the same.
Here’s how you can root your Samsung Galaxy S5 Duos:
Files You Need
1. Your computer must have Samsung Drivers installed on it. Without them, it won’t be able to recognize your device.
2. Download CF-Root for the SM-G900FD to your computer. It’s the device specific file that will help you gain root on your device.
3. Download Odin to your computer. It’s the tool that helps you flash various custom files on your device.
4. You should only try this on a SM-G900FD device.
