Any update on this? I know its discontinued but I really want to try rooting the old S8 I have sitting around as a spare. I don't care if it gets bricked, I don't have anything to lose other than a phone that's been collecting dust anyway... but would be cool to get it working so I can run stuff like Joycon Droid and Macrodroid with root features for gaming stuff.

My S8 is on Android 9, V8 bootloader (8DUD3) and is a Snapdragon. I don't really understand the directions in the Op as it is, not sure if detailed instructions may be missing after it was discontinued.

Trying to root a G950U with the last Pie update for the U (with bootloader v8). My head is spinning and I sure hope some knowledgeable person is still around to help.

In the OP, last edited Jan 31, 2021 -- I wonder if maybe something important got edited out at some point -- Step 1 tells me to copy files to my phone and then "reboot to safestarp [safestrap] and flash system image". But I don't know where I'm getting Safestrap from in the first place. How do I get it there? I've read and re-re-reread the Op a bunch of times, read half a dozen other G950U root threads, and I cannot figure it out. I need Safestrap to install the system img, but, no safestrap on my phone yet.

I know Odin (etc), I've rooted several Samsung phones since the Galaxy S5 plus a whole bunch of other phones (Moto, HTC, Axon) and never a problem of any kind. I know I'm not dumb. But maybe I am having a massive brain-f*rt ( a 3-day one) that's blowing me clean out of the water. What exactly am I missing here?

I'm in a similar situation but my S8 G950U was rooted with PartCyborgs Rom for like two years. Then one day it just became unrooted. I find this thread and tried it. In the end my S8 is now on Bootloader version 8 and no root. I gave up. I have a rooted Note 10 so I'm not wasting anymore time on the S8.
But yeah, seems to be something missing from the instructions or something.

Yeah I was hoping the "new in box" S8 I received would have original Nougat firmware on it, but no such luck.

So after re-reading Lorry's
Post #332 it dawned on me that he quoted something that I can no longer see in the OP . . . this first part below that begins with "8.." but apparently used to come before the Step "1." below it. But now this is nowhere to be found, and I wonder what else is missing before that "8..". Clipping the linked post above to copy here because it's a little easier for me than multi-quoting:

---quote
I got as far as the end of the 1st part: " 8.. Now from here you can proceed to install a rooted nougat rom or one of my safestrap pie roms " - I have done that, everything is happy.

So now the next part!

" 1. Extract system.img from the system_s8_brb1.7z and copy to phone also copy either SuperSu_System.zip or Magisk_System-v20.4.zip reboot to safestarp and flash system image "

---endquote

So again, what critical instructions before or around step "8.." above are now missing? I'm guessing maybe there used to be a Safestrap Rom (or similar) mentioned (and linked) in there before, and I've actually tried to hunt down a V8 BL partition and etc. But no luck. I'm royally stuck. Help???

Edit to add: I'm wondering if I could actually try flashing an s8+ Safetstrap package, like maybe G955USQU8DUD3_SAFESTRAP_ODIN.7z . . . I'm downloading it now just to extract and see what's in it.

Oops sorry Mod..my apologies
I do appreciate the effort. I thought about getting on Telegram just to try to chase down the solution, but I'm already all over the Net and oh so tired of fanning myself out all over the frigging place. I'm actually a bit chronically ticked that Telegram has taken so much away from XDA in recent years. Again, fanning out and thus fragmenting . . .
 
I understand about the Telegram thing but why not remove all steps of the directions instead of just 1 or 2 very important ones?
I've been directed to a few Telegram threads from here. I still come back to xda but many people slowly stop though.
I like that people's real personalities come out a little more over there.

JKruse is very busy. I know he has moved on to other devises. I sent you a PM
I understand that, and I've appreciated jrkruse's work for a long time. Not knocking him or anybody else on his level one bit, in fact I have great admiration for such skill sets. I'm an old IT Pro, "been there done that", pretty much all but 21st-century personal devices. I did try once (built the entire dev landscape on Linux) but by the time I got all that done I was too friggin tired to go any further. Lol.

Found another important clue in jrkruses's Post #147 that confirmed what I pretty much already knew . . .

"You cannot do anything til you flash the combo firmware and have safestrap installed"

So then I thought maybe I'll just hunt down the combo for my V8 S8 and give it a whirl . . . ? . . . but then remembered jrkruse's comment about too many phones being bricked by Combo fw. Sooooo . . .

So I'm done with domestic-everything Samsung. All the "F" versions are a piece of cake and I've made them work for me before -- maybe "too easy", not enough of a challenge? I dunno.

@Gregbmil1 , yeah, personalities :):cool:(y) but I'm lettin a little too much of that hang out here on xda. Frustration.

Take care guys. Onward and upward.

PS, @butchieboy , I got the Telegram thing and thanks for that, but I've already got far too much of me stretched out all over.

    There is a new root method that I am testing out if interested join the telegram thread to test out if I feel it is safe again I will post stuff here

    Link To Telegram Channel S8_N8_ROOT
    11
    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_s8_brb1.7z
    BL_G950U_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-v21_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
    Directions
    Safestrap Method
    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 system.img from the system_s8_brb1.7z and copy to phone also copy either SuperSu_System.zip or Magisk_System-v20.4.zip reboot to safestarp and flash system image
    2. Flash either SuperSu_System.zip or Magisk_System-v20.4.zip
    3. Reboot to download and flash BL_G950_NOUGAT_V7.tar.md5 in odin
    4. If you get constant rebooting to safestrap flash Nougat safestrap zip while in safestrap
