Disclaimer 1: Although this method does not trip the "Knox Flag" you are still taking a risk by rooting your device. We are not responsible for your blazing fast smartphone with root! Let's hope this one doesn't catch on fire!
DISCLAIMER 1.5: THIS IS NOT FOR EXYNOS OR CHINESE MODELS!

First and foremost, SHOUTOUTS!
- @partcyborg for finding the root method!
- @me2151 for testing on Note 8 and facilitating root on the Note 8!
- @elliwigy for... Shenanigans! And thread template
- @jrkruse For the deodexed system!
- @Chainfire He will be missed! (no he is not dead, just retired.)
- Samsung for the amazing phone and leaving rediculous loopholes open for us to root!


Disclaimer 2: The method to root should be pretty straight forward as the hard work has already been done for you. With that being said, you will need to know how to download files from the internet, extract a zip file and to use ODIN. That is basically it! Oh yea, BACK UP YOUR INTERNAL STORAGE AS THIS WILL ERASE IT! PLEASE BE SURE TO READ ALL THE INSTRUCTIONS THOROUGHLY BEFORE ASKING FOR HELP!


Prerequisites:
- SamFAIL Note 8 Pre-Rooted System.tar/PIT File Zip (in Post #2)
- SamFAIL Note 8 PART 2 Firmware Zip (also in Post #2)
- Comsey ODIN and Normal ODIN (Found in Post #2 Aswell)(Normal ODIN is just in case)
- Well your Note 8 of course, Need to be by a PC and ready to use Download Mode!

Part 1 Instructions:


Basic ODIN flashing here guys... Not rocket science!


Part 2 Instructions:


DISCLAIMER 3:
* SamFAIL DOES NOT TRIP KNOX
* Boot.img is SECURE which means you MUST use SYSTEM ROOT. (Similar to SamPWND)
* This means that MAGISK DOES NOT WORK
* Which also means SAFETY NET FAILS. So any apps you enjoy that require passing Safety Net will most likely not work while you are rooted with SamFAIL
* Again, similar to SamPWND, this root method uses a factory binary boot.img which is necessary to boot the modified system. THIS MEANS BATTERY ONLY CHARGES TO 80% (Thanks Samsung.)
* SamFAIL DOES NOT UNLOCK YOUR BOOTLOADER AND DOES NOT SIM UNLOCK YOUR PHONE.
* This *should* in theory, work for other Snapdragon Models of the Note 8. If you have another model and are successful please post so we can add "support" for other models.


Back to Stock?
- Download the full STOCK firmware of your choice.
- Flash it in ODIN/Comsey ODIN as you would any other time!
- It will take a few reboots for the "custom" splash screen to go away.

[/CODE]

BUGS!:
- Screen sometimes will be bugged out. Fix by turning screen off and back on. Caused by Factory boot files.
- Possibility of Bixby Home crashing.
- SuperSU may ask you to update it multiple times.
