Read post above yours
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] wackthewalrus:
Has anyone with an S8 phone on Android 9 figured out how to reset to the Stock Android 7 image linked by the OP? I have ADB working and am able to run `adb reboot bootloader` to get in the download mode, but when I run `fastboot devices` it doesn't show any devices and Odin isn't able to apply the Stock image because of it. I browsed all over the internet trying to see if there was a driver I'm missing, but everything seems to suggest the issue is that I can't toggle OEM unlock in the debugger setting in order to flash to the stock image, but I need to flash to the stock image before I can have root to get around OEM unlock. Any help would be much appreciated.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] butchieboy:
Well if you have United States device there is no OEM unlock. Why are you trying Fastboot commands when S8 has stock recovery or safestrap? What are you trying to do that you cannot do with Odin or safestrap
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] wackthewalrus:
Yeah, I have a US Unlocked S8 phone (model SM-G950U1) running on Android 9. Since the OP mentioned "Stock U Firmware Flash First In Odin", I assumed that meant you had to use Odin to replace the image with Android 7 before using SafeStrap. I'm not really familiar with SafeStrap, but by "stock recovery" do you mean to do a factory reset instead of replacing the firmware with the files in SM-G950U_VZW_G950USQU8DUJ1.7z?

When my phone is in download (bootloader) mode, Odin sees the device but always fails. I assumed that was for the same reason that fastboot isn't able to see the device once it's in the bootloader. I don't see a Samsung ADB Bootloader Interface device in Device Manager either, but every driver I try to install doesn't seem to have one.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] wackthewalrus:
In case it helps, here are some screenshots of Odin failing and my S8 in bootloader mode.View attachment 5950167View attachment 5950169View attachment 5950175
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] butchieboy:
You can only have root on Nougat system.img. So to get root follow the steps in Op Android 9 cannot be rooted. Fastboot commands are for devices like Google Pixel
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] wackthewalrus:
So, maybe I'm missing something, but the OP steps basically say to make sure you're on the Stock firmware using Odin before starting any of the other steps and doesn't go into any detail about how to do that.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] butchieboy:
Yes follow the OP instructions
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] wackthewalrus:
There aren't any for installing the stock firmware without using Odin though? Apologies if this is obvious, but could you link me to a guide somewhere for how to replace the firmware with the stock firmware the OP linked without using Odin (since you need Root to use Odin)? Either that, or copy and paste the section you think the OP says to follow to do that without Odin? I'm super lost right now since I've never rooted a phone before in my life and all the instructions online are for Android phones that actually have the OEM unlock feature and can use fastboot.

For what it's worth, I did search on Google and this forum for 3-4 hours trying all the keywords I can think of and haven't found anything that shows how to do that. So any links or copy/pastes would be helpful.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] butchieboy:
You don't need root to use odin
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] butchieboy:
You can't install stock firmware without using Odin. Download the firmware and extract it. After extracted you will have Ap..Cp..Bl..Csc. Using Odin you place in correct spots. Bl in Bl..Cp in Cp and so on. Your trying to root and don't know how to use Odin? After your on stock follow the directions. You will get more help with this on the telegram channel
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] butchieboy:
You need to get away from the fastboot. This is not a Pixel or Moto device. And the OP clearly states there is no OEM unlock and if it does appear it's useless.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] wackthewalrus:
Oh, that's good to know. I wonder why Odin fails for me then. It doesn't give any useful error messages either (as you can see in my screenshots), but at least from your confirmation I know to search for Odin/Samsung failures on Google.

Yup, I did exactly that. I extracted the file and it had 6 files which I popped into Odin (mapping "BL" to "BL_", "AP" to "AP_", "CP" to "CP_", "CSC" to "CSC_" instead of "HOME_CSC_", and ignoring "USERDATA"). My S8 was in download mode, has USB debugging enabled, and appeared to show up in Odin as "ID:0/004", but when I hit "Start" it immediately fails after saying "SetupConnection..". I'm not sure if "ID:0/004" actually means it successfully connected, but it doesn't even fill the progress bar at all, so maybe it isn't actually connecting.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] butchieboy:
Are you using USB mini
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] wackthewalrus:
Not a USB mini, but a USB 2.0 mini hub that converts USB-C to a USB 2.0, HDMI, and USB-C. If the issue is Windows 10 though, maybe I can try with an old Windows 7 laptop.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] wackthewalrus:
I went ahead and tried using a USB 2.0 to USB-C instead and it at least got to "Initialization..", but after being stuck on it for 5 minutes it just failed again. The progress bar didn't fill up at all either.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] wackthewalrus:
So, I spent some more time looking around and I was able to figure out that the Stock Firmware linked by the OP actually isn't for my phone/carrier (SM-G950U1/XAA), but I was able to find the actual firmware here. However, from another guide I watched on Youtube, I heard that you can't install firmware with lower versions of your phone's current bootloader version in which case my bootloader version (going off "G950U1UEU8DUG4" under "Build number") is version 8 which according to the firmware site only lets me go back to earlier versions of Android 9 and not the actual Android 7 Stock firmware. So, unless the first version of Android 9 is good enough, it sounds like I'm screwed here.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] butchieboy:
You cant downgrade firmware unless it's the same bootloader version. I think you are confused. You can only root with a Nougat system.img after you have done the process. You flash stock firmware to your device which is bootloader S8 or U8. You can't flash a stock firmware that is S7 or U7 bootloader. Sounds like that is what you are trying to do. You device should be on bootloader 8..you can only flash stock firmware that is bootloader 8. That is why Odin fails if you are trying to flash a lower bootloader version. There is nothing in OP that states to do this. Flash the appropriate stock firmware then start the process.

[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] jrkruse:
It’s explained in the OP
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] jrkruse:
This is a paid service because it is done by creating a token that is device specific which allows custom images to be flashed basically the same thing as having an oem unlock on phone just this is for US 8 series that doesn’t have that ability. It allows you to do the same thing as a device that is oem bootloader unlocked
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] anmac1789@gmail.com:
How is the token created ? and how much for this paid service?
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] jrkruse:
You need to follow link in the OP where it says purchase and prices and questions about it can be asked and answered there. This is not my service and I don’t make money from it. I just provide the stuff for you once you purchase it. I don’t want to give contradictory answers to the person doing so it’s best to ask him directly.

Phone is in original untouched condition running android 9(pie), G950USQU8DUD3 software. I would be willing to roll back and root if I could use firmware/software that would allow volte switching, which as of now does not have the option to turn on. It was a T-Mobile phone that I had carrier unlocked and switched to Red Pocket(att). Now I have no incoming or outgoing calls because there is no option to turn on volte, even though this phone is whitelisted with att.

[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] vahidhal:
I love you bro
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] billa:
The G950USQU8DUD3 has VoLTE built in, and it's turned on by default for all carriers, therefore there's nothing you can turn on with or without root. The issues is with RedPocket which uses ATT prepaid service and they do not allow VoLTE on non ATT devices, meaning if the IMEI is not an officially supported device. Both the phone and the IMEI has to be VoLTE capable on ATT. Even if you manually turned on VoLTE on the phone, it still won't work due its IMEI not being supported by ATT. Text and data will work since they don't use VoLTE.

ATT sucks, consider switching to a Tmobile or Verizon prepaid, they have no issue with VoLTE as long as your phone supports it. I work with carriers, and deal with these issues every day. Hope that helps.

Just wanted to say thanks for your hard work then ask, now that I am rooted and have flashfire, what do you folks think the best rom to run would be?

I currently have build G950USQU6DSG7

If I understand things correctly, this root method will not work for me until I upgrade my sprint stock rom to a V7 bootloader. To do so I would need to load a newer Stock Sprint Galaxy S8 image in the form of G950Uxxx7xxxx. Is this correct?

If so, I am using SamFirm to find the latest ROM. It says the latest ROM is G950USQS7DTA6.

However, this Combo file is G950USQU7ASK1. Will the combo file only work with ROMs that are older than it?

In otherwords will COMBO ROM, G950USQU7ASK1, work with the latest Stock Sprint ROM ==> G950USQS7DTA6??

If the answer is yes, where would I find a stock Sprint Galaxy S8 rom that is older? I'm seeing a lot of sketchy links to what may or may not be older roms.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] jrkruse:

Thank you so much for your extremely quick response, and for your patience with me.

This started last night when using xposed fw I screwed up and ruined my functioning rooted nougat rom. Then made things worse when I didn't just simply re-flash the sysmtem.img but rather went and tried to restart from scratch by flashing a stock rom that I thought was the same I used that last time I successfully rooted. It wasn't. I was on v5 last time and ended up upgrading to v6 and, since you can't go back to v5 from v6, I invalidating the entirely well documented procedure that I used last time.

So I found myself in between a procedure that worked for me the last time and what I thought I had to do this time. Glad I checked first.

It looks like the download link is.... well it's not broken, but... the file isn't located on the CDN.

So at the bottom of that post [post #2] it links to ...

New V7 Pie Rom With Safestrap For The S8 SM-G950U/U1 Can Be Found In The New Threads Below

New DTA6 Pie Rom With SafestrapFor S8 With V7 Bootloaders​

The instructions there suggest i should upgrade to v7. It gets a bit confusing after that. help?

---------- Post added at 12:41 AM ---------- Previous post was at 12:01 AM ----------

I started with v6 BL on Pie. After flashing the Combo file, I was on v6 of Nougat although I hadn't realized that. So I chose incorrectly based on the instructions. But the mistake wasn't fatal. I didn't have to start over. I re-chose the correct option and proceeded as if I had not made a mistake. I am at the setup screen now.

I'll test root in a bit...

BTW, there is a very minor typo in the file name of step #1 part b. The filename doesn't match what's in the archive. I suspect a newer file was put in the archive and the instructions referenced the older file.

Thank you for the help.

New unlock & root method worked great. Fastest root I've ever done.

Process for my G950U1 (special steps 5-7):

1. In download mode flashed BL_G950USQU8DUA2.....md5

2. Phone auto-rebooted to System, ran quick setup (maybe didn't need to?)

3. In download mode flashed the purchased token AP_G950U1_[myDIDnum].tar in AP slot

4. Rebooted to download mode, no Prenormal, all good

5. Powered off, inserted SIM card (again this is for the U1)

6. Flashed SM-G950U1UEU8DVD4_UNLOCKED_Firmware without AIO (empty Userdata slot)

7. Rebooted to system, connected to Wifi & ran setup

8. Rebooted to download mode, no Prenormal

9. Flashed AIO (the FORCE_WIPE one) in Userdata slot (with "Auto Reboot" checked)

10. Phone rebooted to TWRP and executed some stuff, and then booted to System. Done. (y)

Between steps 3 & 4 (after flashing the unlock token) I might have rebooted to system before going to download mode. Can't remember, sorry.

I got a lilttle nervous at step 7. With the SIM card inserted, right after I started setup (with Internet) the phone said it needed to reboot to install something... ??? ... but whatever it did, no problem. Finished setup without a hitch. (Note, I use Ting Mobile which works on either T-Mobile or Verizon, depending on which SIM card is in the phone. I used a T-Mobile SIM from my daily phone.)
