You are try to downgrade firmware which you can't do.
You can only flash bootloader version 5 or higher ( 5th number from right of the firmware )

Could you help me ?

No. ( There maybe a custom rom that's Oreo favoured )
There are a few websites to down load firmware like Sammobil or updato. ( can be slow download though )
If you want the latest version of firmware you can use PC app call samfirm or frija.

friend same problem here, I'm wanting to install custom recovery, already everything is active oem and everything but is saying the issue of birary 5, I'm using android pie last version of November. I was told the question of 168hrs and such to be able to do the custom and I'm squeezing complete this time.
if anyone knows how to do it faster I'm waiting

Waiting
Someone here on xda developed a new program to find and download the correct Samsung firmware called 'FRIJA'. which is the successor to Samfirm.
https://forum.xda-developers.com/s10-plus/how-to/tool-frija-samsung-firmware-downloader-t3910594

any news? did you manage to downgrade? i'm having the very same problems ..

ok weird but Start with new drivers maybe make sure your on a usb 2.0 port 3.0s cause issues....
Reg odins are for stock firmware and comsy is for the PCRom firmware
only other thing i can think of is you are on a revision 2 bootloader trying to flash revision 1 stuff which will always fail as antirollback
or nearly same error
How do i know which bootloader version the phone is on?

Are you on the QI5 bootloader? If you are, that's most likely the problem.
And are you trying to downgrade? If you are and you're on the QI5 bootloader, it won't work cos the QI5 bootloader is locked.

Odin and TWRP first Timer! Could use a hand!

Hello guys, first of all thanks for any consideration towards solving my problem. I'm at my first attempt of flashing/rooting a cellphone and I'm going to do so on a Samsung Galaxy S8 (SM-G950W).
Code:
Android version 7.0
Baseband : G950WVLS2ARA1
Build Number : NRD90M.G950WVLS2ARA1
Android security patch : January 1, 2018
So basicly I've been following THIS GUIDE to install TWRP, the steps were to download Odin (Ver 3.12.3), the TWRP .tar file for my phone which should be the SnapDragon one, Samsung Drivers and Samsung smart switch (I guess for a backup?). Developper Options are activated and Usb Debugging is as well. Once I put my cellphone on Download mode, I connect it to my PC, Open Odin and load my img.tar file on the AP slot (twrp-3.2.1-0-dreamqlte.img.tar).
Once I press start I get this error on Odin :
Code:
<ID:0/004> Added!!
<ID:0/004> Odin engine v(ID:3.1203)..
<ID:0/004> File analysis..

<ID:0/004> Get PIT for mapping..
<ID:0/004> Firmware update start..
<ID:0/004> SingleDownload.
<ID:0/004> recovery.img
<ID:0/004> FAIL! (Auth)
<ID:0/004>
<ID:0/004> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)
<ID:0/004> Removed!!
And I get a red message on the phone's console saying :
Code:
SECURE CHECK FAIL: recovery
I've been looking around for an answer on google, many and similar issues but I couldn't find the exact same thing so I thought why not ask the experts!
Sorry if it is too much information I'd rather make sure you guys have enough hints to see what I'm doing wrong.
Thanks in advance towards any solution.
You missed the part that says "You need to have an unlockable variant such as Chinese or HK to flash" your canadian s8 is locked, can't flash twrp on it.

Thanks Peachpuff, so what would be my next step? Is there a way for me to unlock this?
I have to unlock it from Telus (Carrier)?

No, there is no way to unlock the bootloader currently on the G950UW. Unlocking the bootloader and carrier unlocking are 2 separate things. This means TWRP / custom recovery is impossible at this moment.
Although root alone is possible, and the way it's done has awesome benefits.

Can't turn on my phone, can't open twrp, Odin fail Galaxy s8

Hello everyone,
I'm following this forum for mounths but just had chance to register.
I tried to root my phone, then I think something went wrong. Turned on the phone and used for a while, but had a fingerprint sensor error. After that I reboot the phone, but while showing the Samsung logo, I got "only official released binaries are allowed to be flashed" top of the screen. And phone was automaticly turning off after that.
Then I put the phone download mode and tried to install official firmware. Odin was failed.
I tried to flash bootloader only, and fail neither.

I thought maybe the stock rom that I trying to install is older. But now I can't open the TWRP with the buttons for the wipe data. The Samsung Galaxy logo views, after that it turns off.
Trying to install twrp again, Odin gives me fail too. Now I can only open the download mode.
I need my phone today urgently for contact with my colleagues.
Please ask me for the missing informations and please help me ASAP.. Sorry for my bad and complicated English..
Try to flash an earlier Version of the bootloader maybe QF7.
I found the flashable odin archive at https://mega.nz/#!5Q4TATzQ!DT2OQO01KHfw7HsVNElZSfZ4DHoO9W99k3dJqfumMhg for s8 and at https://mega.nz/#!dMZ0zbDL!oYrcBh8DeOqMFeO9QObu8eNXVrjsajXICJ0o3MJPJ-o for s8+.
I also find a video for this issue at https://youtu.be/VTi3uBkpJic
Try this and reply back..
- ————————————
Or just try to flash the stock rom without the cm.bin/ bl firm.

You'll need to flash a firmware that is b8. Check the last 5 digits... It needs to be an 8, you are using a 4 firmware

Good, in advance I appreciate the help you can give me since the phone is unusable, it is a Galaxy S7 G930V and I am stuck in a firmware with binary 8.
The issue is that the mobile was super well running Turrón 7 G930VVRS4BRC3 (binary 4), everything worked perfectly well, one day I decided to update to the latest version for then Oreo 8 G930VVRS4CRI1 (binary 4) using Odin 3.13, the phone in his first reboot gets stuck in the Verizon logo, it also heats up a lot, after I forced the shutdown using buttons volume down and on, I turn on the phone and after several attempts manages to start but sending constant messages "Google Play service stopped "," phone stopped "," messages stopped "," clock stopped "," Samsung keyboard stopped "," wifi stopped "" settings stopped ", etc., again and again with each of the applications, not even a minute when the Samsung logo reboots and the same thing happens again, fortunately I managed to flash again the firmware I had previously (Turrón 7) and the mobile continued to work perfectly if No problem.
As time goes by, a new update of Oreo 8 G930VVRS8CRK1 (binary 8) is released, which I updated thinking that all those problems had been solved and I have found that the same errors continue.
When I try to downgrade by flashing the Turrón 7 G930VVRS4BRC3 (binary 4) it happens to me exactly like the fellow @ humana101.
I have flashed the binary firmwares 8 of the G930T and G930U versions downloaded from both Updato and Sammobile and with all of them the same bootloop and close of APP occur.
I have come to the conclusion that the problem is that my Oreo 8 update does not work for my device.
Can someone help me downgrade again Turrón 7, find some firmware that serves me or some Turrón 7 with binary 8?
The device is useless, help!:llorando:
can we downgrade binary
