This method is brought to you entirely by @elliwigy He is the reason for this exploit and method.
With that being said, Extreme Syndicate Root is now available!


You can be on any version bootloader. This will update you to V7 bootloader
This method will work if you are on Android 9 Pie but will put you on Android 7 nougat. There is no root for Android 9 Pie
You will not be able to use normal magisk
You will not be able to flash custom rom like Lineage or any other AOSP roms
You cannot flash custom boot images or recovery images such as TWRP
Odin does not work on some later computers with USB 3.1 chip controllers the only work around is using a USB 2.0 mini hub
It is your responsibility to make sure you can use adb properly
Root may break things such as safetynet so deal with it


Disclaimer:

The Extreme Syndicate team and it's affiliates are not responsible for your actions or your device if any issues are to arise. You flash this and utilize these files at your own risk. You have been warned!


The Adventure!:

This is a modified version of @elliwigy Extreme Syndicate Root for S9/N9 modified to work on the SM_G950U/U1 S8

Also, donations/money is not expected or required but if you feel obliged to share what you can then that would be greatly appreciated! Donations keep me on the grind and sometimes can even help me in acquiring other devices to work on. I had issues with Paypal a while back (SamPWND days) and do not have a Paypal account. I do however have a Venmo and Transferwise accounts that work in most situations.

Venmo - http://www.venmo.com/Thomas-Huntington-10

Transferwise - PM @elliwigy for info to donate using Transferwise.

This method is different from the S8 method because original samfail method still works on s8+ so this really is not the Extreme Syndicate Root Method as provided by @elliwigy but to keep the 8 series uniform I will just call it this method

Directions For SM-G950U/U1/W S8 Can Be Found Here
Directions For SM-N950U/U1/W Note 8 Can Be Found Here

Downloads
SM_G955U_RESCUE_ROM_V7.rar
BL_G955U_NOUGAT_V8.tar.7z

Instructions
If you didnt upgrade to V8 bootloaders using odin. I recommend flashing full stock firmware with V8 bootloaders even if you are already on V8 bootloader via OTA update. I feel that maybe something in the OTA from V7 bootloaders to V8 may have corrupted a bootloader file and some people have experienced bricks with trying to update to V8 bootloaders from V7 using the below method so I recommend flashing full stock V8 firmware in Odin before trying this method and just understand there has been a risk of bricking device. Full stock can be found on Sammobile or updato or any other service you can find it. You will have to reroot of course. If you Updated to V8 bootloaders using odin method already then no need to do so again
1. Extract SM_G955U_RESCUE_ROM_V7.rar
2. Reboot phone to stock recovery and wipe data then from stock recovery reboot to bootloader.
3. In odin flash the BL_G955U_NOUGAT_V8.tar.md5 in BL slot and when finished force the phone to reboot too download mode
4. In download mode flash the AP_SAFESTRAP_RESCUE_SYSTEM_IMAGE.tar.md5 in AP slot when finished phone will reboot and odin will say failed. Phone will reboot to screen that says update failed or software failed this is fine your phone is still in download mode. If phone reboots to upload mode just force reboot too bootloader
5. In download mode flash the BL_G955U_NOUGAT_V8.tar.md5 in BL slot in odin and let phone reboot
6. You will now have a barebones bare minimum rooted nougat rom with safestrap installed. Its only purpose is to give you safestrap so you can continue below and follow directions to install latest version pie rom

Rooted Nougat Rom

This is last nougat rom made for S8 it is prerooted with flashfire and safestrap preinstalled. It has CSC stuff for all carriers added. Its debloated slightly with knox removed. Some stuff may not work but im not sure as I cannot test but this stuff may include fingerprint and or face recognition. If stuff doesnt work it probably related to using pie modems and non-hlos on a nougat rom which you have no choice.



Downloads
system_s8plus_brb1.7z
BL_G955U_NOUGAT_V8.tar.7z
Includes Fingerprint and Face Unlock fix for above nougat rom. Just flash in BL slot in odin after everything else
Magisk_System-v20.4.zip This is system magisk not the normal systemless magisk so magisk hide and modules will not work!
SuperSU_System.zip
Safestrap-4.12-T01-DREAMQLTE_PIE.zip Will boot straight to safestrap only for pie roms
Safestrap-4.12-T01-DREAMQLTE_NOUGAT.zip Will Give you the safestrap splash screen on boot

SM_955_Mods_Safestrap_NOUGAT.zip Will fix volte icon

So what exactly happened?


Sent from my iPad using Tapatalk
i was on a g995u1 firwmare(bootloader v7) although i was having issues with "no signal". i thought maybe if i follow your guide to return the rom back to nougat my network would return to normal.
i only flashed this file "BL_ENG_BOOTLOADERS_SAFESTRAP_G955U_V7.tar.md5".

ps. i did tick the "nand erase" in odin.
the flash completed but my phone went black and did not reboot again.. i disconnected hoping to get it back to download mode again but nothing was working. i have tried using volume down and power keys but this only causes the a little part of the screen to flicker for less than a second.
my battery was 99%. I dont have qualcomm drivers installed. i am installing one as we speak, i have seen some threads with similar issues like mine but no solutions.. thanks for your response..:crying::crying::crying:

It happens once in awhile for no reason. Nand erase may have had something too do with it. I never use nand erase except if going back too totally stock from a modified system. I responded too your pm. You’re phone can probably be fixed with edl files but you are going too have too take your phone apart and jump some test points to make phone enter edl mode

I use to have pics and stuff but I lost them on a hard drive that failed. I can tell you they are on the bottom side of the board and you have to pry back a metal heat shield to get too them

You have to take board out and flip it over. The points are on the bottom side


Sent from my iPad using Tapatalk
OK, Thanks for the response. i see two large heat sinks with the larger one at the top and the smaller at the bottom. i assume the points would be hidden underneath the bottom sink. now i have to figure out a way to pry those metals off... so much work..lol..:D:D

Will this work on all V7 Bootloaders?

I am currently on DTF4 and noticed your on the Verizon page you posted for the DTB3 Bootloader. Thanks for your time and efforts.

Thanks this worked for me! Is there a guide on how to reverse everything if I wanted to make the phone normal again? Like it would be factory out of the box?
