How to root the Galaxy S6 and S6 Edge on Android 5.1.1

If you have a Galaxy S6 or Galaxy S6 Edge running Android 5.1.1, you might have found out that the one click methods in this guide will not get the job done. This is because Google and Samsung made changes in 5.1.1 that require a modified kernel to be flashed in order to root. Unfortunately, there isn’t a one click method available, so it will take a few extra steps.
Note: Rooting your Galaxy S6 or S6 Edge will trip Knox, which means you will not be able to use Samsung Pay.
This method will be successful for most Galaxy S6 and Galaxy S6 Edge devices, but not the AT&T and Verizon Wireless versions. Those devices have bootloaders that are too secure to unlock.
Here are the model numbers that will work with this method:
Galaxy S6 – SM-G920F, SM-G920I, Korean SM-G920S/SM-G920K/SM-G920L, T-Mobile SM-G920T, Sprint SM-G920P, US Cellular SM-G920R4, Canadian SM-G920W8
Galaxy S6 Edge – SM-G925F, SM-G925I, Korean SM-G925S/SM-G925K/SM-G925L, T-Mobile SM-G925T, Sprint SM-G925P, Canadian SM-G925W8
These devices must be running Android 5.1.1. Do not attempt to root using this method if your device is on any other version or if your model number isn’t listed.
Make sure OEM Unlocking is enabled on your device. Open Settings. If  you do not see Developer Options towards the bottom of the Settings screen on your device, follow these steps to activate them.

1. Tap on About Phone and find the Build Number.
2. Tap on the Build Number seven times and the Developer Options will appear on the main page of the Settings.
3. Tap on the Back key to see the Developer Options.
4. Tap on Developer Options.
5. Check to enable OEM Unlocking.

Below are simple instructions, but you should hit up Max Lee’s post for more detailed info.

1. Power off your device. Now hold down the Volume Down, Home, and Power buttons together. After about 5 seconds, you will see a warning screen.
2. Now tap the Volume Up key to put your phone in ODIN download mode.
3. Download the appropriate root kernel from here.
4. Download ODIN v3.10.6 from here.
5. Download the Samsung GalaxyS6/S6Edge USB drivers from here.
6. Connect your phone to your computer via a microUSB cable.
7. Run the Odin software and make sure there is a COM number in the blue highlighted box. If not, then your USB drivers are not installed properly.
8. If everything is a go, Click on AP and select the root kernel that you downloaded earlier.
9. Click on Start. The process takes about 5 seconds.
10. You should now see Pass at the top left.
11. Reboot and you will now see the SuperSU app in the app drawer.
