Hey I just want to make sure I'm understanding this correctly, this gives us root on V5 BL right? Only for nougat image I'm assuming but this also gives us safestrap to hop between Oreo and pie too? If that's what I just read, this is exciting news and major congrats to [MENTION=1949695]jrkruse[/MENTION] and a major thank you to him and everyone that helped!!! Your dedication to development with our S8 generation devices is GREATLY appreciated by the community!

I pulled the system.img from a stock BRB1 firmware on SamMobile, flashed via safestrap, wiped data, and went through the process of exiting safestrap. Everything appeared to go smoothly except I can't boot past the splash screen. Well, the screen goes black about 2 seconds after that. Can you tell me where I went wrong? (Besides acting like I knew what I was doing all along ;) ) I went back into safestrap, and was able to mount system and the Nougat system files were there, but still won't boot. Thanks again - your dedication is not without appreciation.
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
Did you flash the nougat boot img needed for root? Im going to assume your on oreo or pie.
[Samsung Galaxy S8 Guides, News, & Discussion] Sagoode:
That would probably help, thanks. For some reason I was thinking all I needed was the system.img. Yes, I came from Pie.
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
Yup. So your trying to boot nougat on a pie loader. If your going to for root. You need the boot img from the rev 5 combination firmware. And a flashable busy box wouldnt hurt either

How can I find what bootloader I'm on I want root
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
5th digit from far end of firmware. More than likely your on a revision 5. There is no root for Oreo. Nougat only And there are many guides here on rooting revision 5 now. Including the op of this guide

What do I need do to get root and be on nougat I'm confused so many steps
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
It can be very overwhelming at first.

I dont know his method exactly. But once you have safe strap you can then flash a revision 2 system img. As the system images are not incremented. Then before you rebot safestrap you can install the nougat revision 5 bootloader needed for root. Flash su and busy box
[Samsung Galaxy S8 Guides, News, & Discussion] bigblood104:
Ok so do I flash firmware v5 sam fail then safe strap I'm follow steps see were I get

---------- Post added at 12:11 PM ---------- Previous post was at 11:17 AM ----------

Once I have safe strap firmware installed how do I flash rooted nougat on smg 950u
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
Im only speculating as im still on 2. But you have to flash all in one run at least on rev 2 i do.

Flash the combination boot img from the combo file extraction. Do not reboot safestrap untill totaly finished flashing all files. So now after flashing said rev 5 combo boot img. Flash either a prerooted nougat rom. Or. Flash a nougat system img. And then su. Then busy box. And a safestrap flashable zip for good measure. When i flash stock img like this i lose safe strap upon reboot. I dont know about his methods above.

So of you reboot before flashing su and stuff your out of luck. And have to start over. Or at least i have had to in the past on rev 2

You can get su. Busy box and a nougat system img here if you want this method. Dont flash my bootloader as its a rev 2

Mannnnn I can't get it these instruction need a video
[Samsung Galaxy S8 Guides, News, & Discussion] bradical711:
Well if you can't understand the instructions of how to install this then this probably isn't for you because the OP couldn't have been more clear.. he linked together everything you would need and most questions have been answered in this thread already of how to install/ what to... Also the corrupted issue is just a bad download which probably means you need to download the files again.
[Samsung Galaxy S8 Guides, News, & Discussion] jkicker:
Usable ROM

I have safestrap working on my sprint s8 g950u. What I have now is either recovery or factory binary. How do I get a usable ROM back on the device? What are the limitations of what I can install, and what method (Odin or. zip or. img)? Thanks for all the work you're doing.
[Samsung Galaxy S8 Guides, News, & Discussion] bradical711:
The answer to that question is literally in step 8 with a link to a thread of one potential ROM to install and how to do it. However since you have done this process you can now install any nougat ROM, Oreo ROM or even Pie ROM for that matter but not all at once because ROM slots don't work for safestrap. And what I mean by that is by flashing the system.img files of whatever system you want (nougat, Oreo, pie) in safestrap and then plus an minus a few more steps... The main thread linked in step 8 will probably be a much better guide of how to install the ROM's you want etc as well as how to. If you have any other questions just ask in the thread linked over there because this thread is just primarily about the EDL method and you'll get more help with installing the ROM itself over in the other thread linked in step 8.
[Samsung Galaxy S8 Guides, News, & Discussion] agentfusion:
Am I understanding correctly that the version number is the important part? Mine is G950USQU5DSC1, and it's the SQU5 part that matters, yeah? Or is the DSC1 also important in this case? I know the stuff prior to the SQU5 is the device model identifier, G950U being "this is a snapdragon S8", and the SQU5 is "This is the v5 bootloader". So does the DSC1 part matter in this context, or should I be fine using ARG4 image as outlined in the instructions here, or would that cause me a bricking for a version mismatch?

I'm not used to phones with locked bootloaders and usually I avoid phones with them, but I needed a phone in a hurry and got a great deal at a T-Mobile store so I bought the s8. I've had it a while now and enjoyed it just fine without root, but now that Pie has rolled out to my device and caused me to have to wipe the whole phone when the update process wouldn't complete without it, I decided now would be a good time to try rooting since I don't have to worry about losing stuff.
[Samsung Galaxy S8 Guides, News, & Discussion] MalharB:
I have used this EDL method to get safestrap on S8 Oreo & pie, it worked fine for me. So it should work for you as well.
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
Nope just that 5 in the bootloader is all that matters. The edl method will work for you. But you can only have root on nougat

Didn't state to unzip file it stated extract every time I tried extract it wouldn't I used unzip app did the job and from there everything was successful
[Samsung Galaxy S8 Guides, News, & Discussion] Superguy:
That's a prick thing to say. If you're like me who hasn't owned a Samsung phone (until now) since the Note 2 and have been working with other phones that do things very differently like HTC and OnePlus, doing things Samsung's way can be confusing at first - especially as Samsung requires more tools and creative hacks than other phones. It doesn't mean the person doesn't have the technical ability or is unable to comprehend what to do. It's this attitude that's been chasing folks away from XDA for years.

I still haven't rooted my phone yet as I'm reading up and trying to understand what's involved. And I still have questions. That doesn't mean that "this isn't for me" or I don't understand what's going on - especially as some of us have been tinkering with phones well before you even left single digits. It just means there's a learning curve involved.

:rolleyes:
[Samsung Galaxy S8 Guides, News, & Discussion] jkicker:
Thanks for the advice, was able to get it working last night.
[Samsung Galaxy S8 Guides, News, & Discussion] agentfusion:
Thanks for such a polite and prompt answer. I have been out of the ROM world for a bit, and it's all become like a foreign language to me. I used to build my own ROMs from source and now here I am struggling to understand what I can and can't do with my S8! So if I use this method, would I be able to roll back to nougat for root, or is this one of those phones where once you've updated past a certain point you're basically stuck? Though, honestly I'm not really sure that I want to roll back after all, just in two days with Pie it's like having a totally new phone. Even the battery life is great.

Sorry I'm rambling, I just saw "root" in the thread title along with my BL version and got excited thinking there was actually a root method for Pie on snapdragon devices. Either way, the fact that there is a method at all with the most recent BL is a huge bit of progress and I'm extremely thankful that there are people who aren't willing to just give up and go "oh well.". We own our phones, we should be able to modify them however we damn well please!
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
Yea we can only root nougat. But this method allows us to install as of now all 3 systems as they are all the same bootloader revision. We have a nougat bootloader revision 5. Oreo bootloader revision 5 and now a pie revision 5. So we can down grade yes technicly. Just not lower that bit 5
[Samsung Galaxy S8 Guides, News, & Discussion] agentfusion:
That's what I was hoping this would allow for. Good to know I wasn't misunderstanding the purpose. Previously when I'd read about root and ROM methods for the S8, it would seem that every time it was for a bootloader a version or two behind the one I was on, with all of the ways of downgrading the BL being kind of risky, with a fair amount of people ending up with bricks instead of phones. Knowing that there's now a (relatively) safe method provided every step of the instructions are read and followed correctly makes me feel a lot better about giving it a try. Knowing that I can simply backup my data, try rooted nougat, and if it doesn't scratch the itch, I can come right back to pie is fantastic news.

I have this up and working with a Nougat rom. If I need to go back to a stock ROM, does it need to be a version with an image and the other components that flash through Odin? Or can I fkash it straight from Odin if its a v5 rom? Thanks.
[Samsung Galaxy S8 Guides, News, & Discussion] Seananigans:
I've been sitting on version G950USQU5CRIB (sprint) for a while now hoping a good stable root method would come out. But this is much more than what I was expecting :D so I can have custom roms now? And I shouldn't have any issues with this method either right? It works for all snapdragon s8's on BL v5?
[Samsung Galaxy S8 Guides, News, & Discussion] seanskiT!:
This is not quite what you think it is. Root is not an option on Oreo or Pie. This allows us to be able to change stock systems, if you want a rooted system you will have to go back to a rooted Nougat.

Oh no I'm aware that this is to give safestrap to my device. But this also puts you back onto a prerooted Nougat right? Does it matter that I'm already on Oreo? And will safestrap let me load custom roms afterwards like say Lineage?
[Samsung Galaxy S8 Guides, News, & Discussion] seanskiT!:
Iti gives you the ability to go back to rooted nougat. No custom ROMs

[MENTION=1949695]jrkruse[/MENTION]...thanks for your work on this. Got my S8 back on Oreo last night and gone with all the dreaded white screens.
[Samsung Galaxy S8 Guides, News, & Discussion] Seananigans:
So just to be sure before I do this which slot in odin does the COMBINATION file go into? It would be AP since it has to do with the system image right?

I've been rooting since my s5 but this is my first time with bootloader stuff and I'm just trying to make sure I get it right the first time. So I appriecate the help guys
[Samsung Galaxy S8 Guides, News, & Discussion] MalharB:
Yes in AP slot
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
It don't really matter it's more for looks. I have flashed csc in ap. Combo under boot. The firmware your flashing knows where it has to go in the end.
[Samsung Galaxy S8 Guides, News, & Discussion] Seananigans:
So I'm stuck on step 3. My device isn't showing up the way the picture on the OP shows. Here's what my computer shows instead:

I' made sure my drivers were up to date before i started and I just reinstalled them again in hopes that would fix it but with no luck. When booted normally it shows up like it usually does under Portable Devices -> Galaxy S8

On the bright side steps 1 and 2 went off without a hitch. Odin flashed the COMBINATION firmware successfully and my phone shows the "Factory Binary" screen and then boots to this:

From there of course all i can get to is my settings but I've confirmed that I'm back on android 7.0

When I do step 2 and open reboot_edl.bat it sends my device to black screen just like its supposed to. But without device manager reading the phone properly I don't know what COM number to use so I'm kinda stuck.

At least I haven't bricked my phone yet haha. It boots back to that screen just fine every time i force reboot so that's a relief. But as it is right now I can't use my phone other than that lol
[Samsung Galaxy S8 Guides, News, & Discussion] MalharB:
Try rebooting computer that might help and

Try different USB port
[Samsung Galaxy S8 Guides, News, & Discussion] Seananigans:
Just tried. No change

UPDATE: Found the problem. Apparently Qualcomm has their own USB Drivers seperate from samsung. I Installed this driver here: https://gsmusbdrivers.com/download/qualcomm-hs-usb-qdloader-9008-driver-64-bit-windows/ And My device is showing up same as the picture in the OP now :D

I'm gonna continue with the rest of the process and I'll update to let you guys know how it goes

UPDATE#2: Alright I completed step 6 Successfully. I'm now able to boot into safestrap which is awesome :)

A couple last questions. So when i boot my phone why does it say "Safestrap: Disabled" even though i can tap recovery and get into safestrap just fine? And also so what now? I assume i have to do step 8 and download and install one of those roms from the link?
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
Safe strap always says disabled. Or does on mine at least. And yes to the second
[Samsung Galaxy S8 Guides, News, & Discussion] Seananigans:
Okay Thanks. In that case there's only one method for rooted Nougat in that list of roms on the OP. It's this one right here:

https://xdaforums.com/verizon-galaxy-s8+/development/root-using-odin-modified-firmware-t3693790

But its for the s8+ Does that mean i can't use it on my standard s8 G950U? Or will it not matter? I know they're basically exactly the same hardware but i want to make sure. Because if not the only rom in that list that is explicitly for the S8 is this one:

https://xdaforums.com/showpost.php?p=76074958&postcount=3

Which is for non-rooted pie.

I'd like root but right now It seems like I don't have an operating system installed at all lol. Just the Factory Binary thing and safestrap. So I'm just trying to get something up and running so i can use my phone again. I really really appreciate all the help!
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
There are a few s8 reg roms but yes follow those instructions
[Samsung Galaxy S8 Guides, News, & Discussion] Seananigans:
Flashed rooted nougat through safestrap without any problems. but on step 3 when flashing BL_V5_Part1_and_3tar.md5 in odin it fails saying "Re-Partition operation failed"

Update: Just completed first time setup and noticed my fingerprint scanner isn't working. But at least my services are working. Any Ideas on how to get the fingerprint scanner working again? Oh and another odd side effect is that the camera app's rotation has been flipped. Don't know how or why. Basically when I'm holding my phone portrait wise the camera flips to landscape and vice versa. I don't know what I'd do about that either.

Houston! We have a problem!

I should have known better. I always tell our customers to follow the guides and kb's step by step and 99.5% of the time it will resolve the issue. I rushed through the first few steps. Here is what I did:

1. Installed COMBINATION via the version of Odin provided.

2. Let phone reboot, it came up to a picture of 2 gears turning. I did not wait for full boot nor did I wipe.

3. Made sure the device was connected as Qualcomm 9008 device, COM6.

4. Ran Recover_System.exe as an admin. The folder has been whitelisted as well. While the Blue CMD screen recognizes the device and allows me to enter the Port #, it appears to start but nothing happens. (see attached pic) I let it go for 2.5 hours and then unplugged the phone. I could see the device disappear in the Device Manager and then reappear when I plugged it back in. When it was not plugged it, I tried to boot nothing. But the fact that the computer still recognizes the device give me a little hope.

Any assistance would very greatly appreciated!

***UPDATE***

It looks like after step one, it is only booting into Factory Binary. Read elsewhere that this is firmware related. Attached more pics. Unfortunately, I have run out of play time today. Will try again on Monday!

If anyone has any suggestions, I sure would appreciate it!

***ANOTHER UPDATE***

Found this youtube video and I am now following that, seems to have gotten me further than before, so I am hopeful!
