Guys, recently I have flashed the stock pie via Odin on my S8+ (SM-G955FD) but for some reasons I want to go back to Oreo, can I do it via Odin, just flashing Oreo firmware, or may I have to do something else?

Yes you should.be able to revert to Oreo using Odin.
The limiting factor is bootloader version number has to be the same as what is on pie version. So basically the latest version of Oreo before the pie update should work.
You usually have to factory reset your phone first too or it'll boot loop after the down grade when it gets to the app optimization screen.

HI I was wondering if anyone could help verify that the downgrade is possible from 6.0 to 5.0 OK4. I used Odin to flash the stock OK4 firmware to my phone when I was on the 6.0MM firmware and I just want some one that is willing to test what I did just to verify that I wasn't just lucky.
What I did was while on 6.0 I setup ADB for the phone, rebooted to download mode and used Odin3-v3.10.6 to flash G900PVPU3BOK4_G900PSPT3BOK4_G900PVPU3BOK4_HOME.tar (got this from sammobile). When phone rebooted it got stuck at the boost logo screen for longer than I liked so I used "ADB reboot recovery" command and in recovery did a factory reset and then booted into system and I am having no issues. So can some one else test this so that I know it is a 100% way to downgrade?
I just flashed the OK4 tar via odin to go back to stock and take the MM update again. I wiped everything but internal and external storage in TWRP first. It's currently downloading the MM update.
i've successfully taken the PCA update twice, and used ODIN to go back to OK4 and update once again.
the bootloader does not appear to lock firmware.

Correct, because when you odin OK4 it restores the stock recovery and everything else etc, so everything is stock again, system status is official etc. then you can either download the OTA as normal or take the zip from your thread and update from stock recovery. i've done it both methods.

I assumed you couldn't revert. That's awesome though thanks

I can also confirm that too, I just did a downgrade to OK4, after I unsuccessfully tried to downgrade to OA6. I assume that pyrochance (http://forum.xda-developers.com/showpost.php?p=66266625&postcount=138) is right.
If i was helpful, feel free to hit the thanks button on those posts
Are you rooted? I'm not rooted, and from BOK4 I was not able to downgrade via Odin to an earlier firmware that supports towelroot. I am now on Android 6 (OTA). Question - on Android 6 is it now possible to downgrade to an earlier firmware (without root, and without tripping knox)? If so is it only to BOK4? Thanks in advance.

Yes. You can only downgrade to OK4. If you weren't able to go to a previous version when on OK4 why would you be able to once beyond it?

Thanks Kreatur3, was thinking that with the new firmware they might have relaxed their restriction on downgrading. I would think that with any new official firmware, they could pretty much do whatever they want, like even take out all protections and allow you to root without tripping knox (which I know they wouldn't), or am I misunderstanding something?

They could allow it but won't. It's obvious with the direction they are going with the s7. I can see why maybe providers don't want you to have that power but don't know why the manufacturer cares. Beyond the pressure from cell phone companies. I don't care about knox personally. I'm way beyond the warranty period and trip it every time the day I gety phones.

You are welcome.
I'm having a bit of trouble. I was on MM, then the phone started freezing up. So I went back to OK4 but I can't get past the Samsung boot up logo. It stays on there forever and doesn't move past it. I even tried to replays through Odin multiple times but still not working. I'm stuck.
I installed Superman Oreo rom and want to go back to the Nougat version, I wiped the phone and flashed Nougat but it just got stuck in a boot loop.It seems the bootloader was updated to version 3 and nougat uses version 2.Does anyone know how I can fix this? I tried flashing the bootloader and modem through Odin but it gives an error.
I want to do the same. Superman 3.10 oreo to nougat 2.90
Have I to downgrade the bootloader?
Thanks for answer

I tried everything i could find and nothing worked i just stuck with 3.10
Try flash first Stock ROM Nougat than Superman 2.90 ;]
I had Oreo Stock and back to Nougat Stock without problems.
Superman 2.90 could need Nougat Stock ROM
Same here.
Was using SuperMan 3.1.0 but was disappointed with Oreo.
installed stock Nougat ROM via odin 3.13, then TWRP and root, nxt SuperMan 2.9.0.
need time and patience.
Make sure your battery is fully charged. and you have stock latest NOUGAT ROM with adequate AP,BL,CP,CSC.
If you have FAIL at 1st attempt, do it again.
I had 2 FAILs before it PASSED.
Tip:
When your Odin process will FAIL, but process isnt finished yet, disconnect phone from laptop and turn off holding power button, Phone will restart into DL mode with big triangle on it saying to use SmartSwitch for PC to recover the OS.
turn it of again and when screen is off but before the vibra, press and hold PWR+Vol DWN+Home, phone will go into normal DLmode, connect then into laptop and press Vol UP to confirm Odin Mode in Download Mode.
Then using Odin, install OEM Nougat OS.
This is the method that worked for me and had successfully installed Nougat.
After that, boot the system, unlock the Dev options in setting and turn on OEM unlock before you go for TWRP and root.
hope it will help.
Goodluck.

Hope this helps:
Go back to Oreo or whatever ROM you can use
Goto settings > developer options
Enable OEM unlock
Now try flashing nougat if you stuck on bootloop then install a custom ROM that is nougat, then try to flash stock nougat. If it still doesn't work there is nothing I can do use a custom nougat ROM. I recommend ultimate nougat

So is there any method to downgrade the ****ing bootloader?
Mine is ver.3 and need to flash ver.2.
I realy not want to stuck on Oreo. Oreo realy have no Benefits.
There is no way to downgrade the bootloader. Samsung blocked bootloader downgrades starting with the S3.
But why cant we just install the nougat bootloader and modem as .zip from twrp if we are on an Oreo rom?
Is this not possible?
Hello,
I am attempting to downgrade from Android 8 to 7 on Galaxy S7. When I attempt to flash the old firmware I get the error 'Device 3 - Binary 2'. Does anyone know if there is a workaround for this yet?

Odin will not let you flashback to a previous boot loader version, you have to do it through TWRP. So either flash the nougat firmware with TWRP first or any nougat based rom, then flash nougat via odin which will remove root and TWRP.

Are there any instructions for this?
Will secure apps (Banking etc) work again after removing root?
I was under the impression you could via Odin if OEM unlock was enabled, without needing TWRP or root. https://forum.xda-developers.com/s7-edge/how-to/guide-how-to-downgrade-android-oreo-8-0-t3821495
edit: As for banking, if you go root then flash back to stock you should have no issues. Even if you stay root, things like Magisk will hide root status from apps and pass safetynet. Your biggest issue would be the loss of Knox, which voids warranty and breaks some Samsung apps.

It is not possible as per some of the replies to that thread. I spent a few hours playing TWRP yesterday and it was not possible either.

Ok so listen, it can be done as i said but it's not easy. The choice you have of course before attempting this is to just install a android 7 custom ROM? many nougat ROMs are just stock with the bloatware removed and the boot-loader version isn't checked during flash.
Here's another way to go back, i can't guarantee it will work though i haven't tried it on an S7.
Downgrade to an older firmware with an older bootloader even if one keeps the newer bootloader on his device.
So what's how's it done?
Download the firmware file (.tar) which you want to downgrade to and open it with an archiver application (7zip). Extracts all the files to a folder and repacks them again in a .tar file but leaving every file out which ends in .bin (e.g. sboot.bin etc.). This .tar file can now be flashed like any other firmware file via Odin and it should run through it without any problems.
Hope this helps.

hello everyone,
i have S8+ with android 7 installed, not rooted and still didnt get any OTA for either oreo or Pie, so i decided to do it manually but i wanna make sure of the steps since it's been a while for me not flashing anything.
first thing i should know is that this update is going to wipe my phone due to the bootloader update
and about that bootloader update, should i flash pie bootloader first or just flash a stock ROM with odin that includes bootloader file ?
any help with this issue is much appreciated

If you are going to update with Odin flash full firmware. ( 4 files )
As for wiping your phone when you unzip the downloaded firmware there will be 2 CSC files.
CSC - Clean install will wipe your data ( same as factory reset )
Home CSC - Dirty install should keep your data
Always do a backup before doing anything.
Note: Make sure after you upgrade your firmware to update your apps so that they will be comparable with new firmware.

Was the firmware that you flashed made for G955FD? If it was not specifically for the G955FD, that is the issue. You need a firmware specifically for G955FD, the other G955 versions of firmware might not be completely compatible.
