First off great work and thank you for all the time and effort you put in. 2 questions. Does this method still not trip Knox? And will you be starting a separate thread for this root method to avoid confusion or just keep it on this same thread?
Both questions get good answers. :)
Q1. Knox is still not tripped. It will be the exact ame conditions a before in regards to knox.

Q2. It WILL be in this thread. the method is the exact same. im debating removing the links to the files that are there and replacing them with the U2 files because the U2 so far feels much better than the current(Feels smoother and snappier). I might just add the links along ide as the method for install is the exact same as it is not. but there is absolutely no need for a new thread :)

ARE YOU READY KIDS??? Heres the news you all have been waiting for. Rev2 has been SamFAILED! I have full root with the SamFAIL method on U2 firmware. Based of Sprints U2BQJB Firmware. There is multicsc already included so there will not be the need for csc just as before. It is currently NOT deodexed. Thats on my todo list. But spread the joy. We have root after Samsung patched us out.

EDIT: This IS rooted however i want to test for a few days to look for bugs before release. This is more of a notice.
EDIT2: Yes there is still the 80% battery bug. Dont ask about it. Each time someone asks about it im testing it one more day before i release it. So keep your mouths shut(and fingers of the keyboard) about it. :)
Amazing news! Can't wait till it's out. I could care less about the 80% bug I just want root :D

I have a radiofm apk i got somewhere else and viper (arise) from the xda thread...radio works fine played through headphones and speaker. I'll post the two files i used viper and radio. (Viper installed through flashfire) and (radio manually copy into a folder of the same name) set permissions on folder (0755) and file (0644).

RadioFM

Viper arise
https://drive.google.com/file/d/0B2kFWHz2n1w0dVBEOFVNRDE1STg/view?usp=drivesdk


Sent from my God Mode 8


Also i think someone in here asked this....But just tested radio with data turned off and it worked just fine.

Wanted to get back to you right quick. Appreciate your uploads. The drive links are the same one (Viper) and when I click to download it, I get this message below. I'm not sure how to circumvent it and have no virus detection. Seems to be a Google Drive thing. Thx!

Updates turned off

So I'm still on U1 software and have security policy updates turned off as well as system set to manual. Yet it still downloads and nags for update automatically? WTF!! I searched through this and other threads, thought turning that sh*t off would work. I guessed wrong? Enlighten me please.

Use package disabler to freeze software update if you are not rooted . If rooted use Titanium backup

Noob question here;

I root my phone and got what I wanted: change the horrible stock emojis and sideload the correct drivers so I can use the PS4 controller without problems, done. Now, is there a way I can "unroot" or something like that without having to delete the System partition? So I can get the 100% charge and my mods even without root.

You cannot unroot without wiping the phone. It's been asked and answered multiple times in this thread.

Stupid question.....does this work with the newest (november) samsung update? Prior to u2 being released I saw the OP called out it would block root, but that warning has been removed.
Thanks for answering

Not sure if i bricked my verizon note 8. I just go into a continuous boot loop with a dying android. and cant do anything but go into download mode. i've been looking for the past 3 hours and can't look anymore (got kids to take care of) is there a guide to reset it to factory and a fast download link for a stock firmware. i'm having to wait about 4 hours to download from sammobile!
Thanks

No it does not work with u2, but a new version for that is on the way.

What mode does the Note8 have to be in to charge above 80%. I know someone said they were able to charge the device over 80% when he gets ready for work...

It has to be on the screen that's right before the download mode the one where you press up to continue or down to cancel... You leave it there then after so long press down to cancel and reboot.

Louforgiveno charges it on the screen right before download mode. You can also get it to charge in download or upload mode. The only way I've personally been successful is in upload mode. But it was said you need to keep it charging/plugged in when you restart and have it below 80%. I haven't tried with it plugged in yet. However I'm fine with upload should it come to that.

    As of 8/28/18 SamFAIL is officially depreciated. There is no new root method at this time and i will not be helping find another one. Bootloader V3 is the final version of SamFAIL for Note8. DO NOT PM ME ASKING FOR HELP!!!

    Introducing:

    SamFAIL!

    Root for the USA Snapdragon Samsung Galaxy Note 8! (N950U,N950U1,N950W)


    WARNING! The latest Note8 software update(U4XXXX) blocks samFail(All carriers.). DO NOT UPDATE IF YOU WANT ROOT!
    SamFAILv3 Has been Released There is an addititonal step in Part 1 for V3 ONLY.

    Bootloader check guide(Green can be rooted, Red can not be rooted)
    Last 6 of firmware version(X can be different):
    U1XXXX=Bootloader V1
    U2XXXX or S2XXXX=Bootloader V2
    U3XXXX or S3XXXX=Bootloader V3

    U4XXXX or S4XXXX=Bootloader V4
    U5XXXX or S5XXXX=Bootloader V5



    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:

    IF YOU ARE ON U3(Rev3) bootloader you must Flash SamFAILv3_N8_FIRMWARE first THEN do part 1 THEN part 2 again. This IS a requirement. Not optional. Otherwise for U1 and U2 proceed as normal.
    1) Unzip the SamFAIL Note 8 Pre-Rooted System.tar and PIT File to your PC.
    2) Have Comsey ODIN up and ready. Place your Note 8 into Download Mode and Connect to PC
    3) In the AP slot, select the Pre-Rooted system.tar.
    4) Now go to the PIT tab(Click OK or close on the warning box) and click and navigate to the PIT file you also just downloaded and select it.
    5v6fyv.jpg

    5) On the OPTIONS tab, you will select the following: Auto Reboot, F. Reset Time, NAND ERASE ALL, and Re-Partition.
    6) Once you have everything in place and the correct options selected, press START.
    7) ODIN will say FAIL at the end of the flash and the phone will have rebooted to upload mode saying "Unknow Error". Don't fret however, the system should have still been written!
    2zywydi.jpg

    8) You will have to get the phone back into Download mode( Hold Power, VOL- and bixby together and the phone will reboot to download mode and tell you its in emergency mode. THIS IS NORMAL.) and then proceed to Part 2 Instructions!


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


    Part 2 Instructions:

    1) Download and Extract the SamFAIL Note 8 Part 2 Firmware Zip to your PC
    2) Click Reset in Comsey ODIN or close it out and re-open it so it is COMPLETELY cleared out
    3) Now select the firmware. BL goes in BL, AP goes in AP, CP goes in CP, dont press start yet!
    4) Now, this time we ARE NOT SELECTING A PIT FILE, We should just select Auto Reboot and F. Reset Time. DO NOT DO NAND ERASE ALL OR YOU WILL HAVE TO START OVER.
    5) Once you got the partitions in place and the right options selected, Press Start!
    7) Once phone boots up, Setup your device as normal and proceed to the SuperSU app. It may ask you to update the SU Binary. Select Normal method and let it do its thing. Follow its instructions then SU should say it was Successful in updating and it needs to reboot(You may have to do it multiple times. I believe its 2 or 3 times then its good) ENJOY SamFAIL ROOT!


    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.

    Donations:
    As always, the devs have been hard at work recently to bring you root. Donations are definitely NOT REQUIRED but if you feel generous and want to spot the devs a few bucks for their hard work you can donate to this Paypal Address:

    Donations


    DOWNLOADS will be in POST #2
    UPDATES will be in POST #3


    As always, ENJOY ROOT and thank SamFAIL for making it all possible!

    Telegram Group has been closed.

    P.S. See why we called it SamFAIL now? Massive fail on Samsungs part.

We have root after Samsung patched us out.

    EDIT: This IS rooted however i want to test for a few days to look for bugs before release. This is more of a notice.
