Rooting can be done using Chainfire’s popular CF-Auto-Root and ODIN tool, which is perhaps the easiest way to gain root access for those looking to stay close to stock firmware. The below guide installs SuperSU binary & APK and Stock recovery to your Galaxy S5.
Before proceeding, Note that:
1. Check your device model under Settings > About device > Model number. Make sure the device mode number is SM-G900F.
2. Install Samsung USB drivers on your Windows system. (Download v1.5.40.0)
3. Download CF-Auto-Root-klte-kltexx-smg900f.zip and extract it to a folder.
4. Boot your device into ODIN Download mode: To do so, power off the phone. Now hold down the ‘Volume Down + Home button’ and while holding both of them simultaneously, press the ‘Power’ button until you see a warning screen. Then let go of all the buttons and press ‘Volume Up’ to enter into Download mode.
5. Then connect the phone to your computer via USB cable.
6. Start Odin3-v3.07.exe. ODIN should show a port number in the ID:COM box which depicts that device is connected successfully.
7. Click just on the ‘PDA’ option in ODIN and don’t touch any other fields. Browse and select theCF-Auto-Root-klte-kltexx-smg900f.tar.md5 file. Make sure Repartition is NOT checked.
8. Click on Start and let the process complete, phone will reboot itself. You should see a PASS message in ODIN. You can confirm root privileges using the ‘Root Checker’ app.
Voila! After the device reboots, you should see the SuperSU app installed
