On what build are you ? If you on BQA6 you are on official Nougat firmware. You don't have to do anything. If you are on BQA4 you need to use Odin from this post : https://forum.xda-developers.com/att-s7-edge/how-to/firmware-pi2-s7-edge-sm-g935a-10-03-16-t3477246 and firmware from here: https://forum.xda-developers.com/att-s7-edge/how-to/firmware-s7-edge-sm-g935a-g935aucs4apk1-t3549458

I used regular Odin (3.12x) For returning to Stock MM. Done it twice already with no problems. I used Princes for rooting.

Flash a stock firmware using odin. Try that, but you will lose everything.

I have used CWM recovery 6.0.4.7 to wipe and flash.
Try to flash the latest Modem and Bootloader with Odin, I think you can find them on Audax page. Good Luck!

No, go to Samsung updates.com or Sam Mobile and download a firmware for your phone. Firmware is an orginal "rom" for your device From Samsung, and flash it using odin. Your problem could be with the efs files, I had that issue Too with my note 3, you should always back up Your efs files.
Goodluck!
The rom on the phone is probably not compatible with the phone's current modem and or bootloader.
I recommend flashing the latest stock rom via Odin, make sur everything works, then install twrp and a custom rom.

Damn shame I can't get it to download.
Been on Oreo for a long while. Check it out, https://forum.xda-developers.com/galaxy-s8+/how-to/guide-oreo-beta-usa-snapdragon-s8-t3700907
PLEASE read, search. Likely your question and how to get started has already been answered, happy flashing!
Not going to try. I hear it works but it's a t mobile version. I'm going to wait for official Verizon OTA as is need to reload the nougat load to get the OTA later. Besides, that wipes the phone since it isn't an upgrade.

Downloaded the ZIP. Placed on my sd card. Ran recovery. Installed zip. Took under ten mins. Rebooted itself. Once rebooted it was on Oreo with no reset, everything was the same. Super easy.

Took the gamble... on the boot up from odin back to BQL1 it corrupted my device storage.

Before flashing the firmware you need to flash the marshmallow bootloader and modem for your device then you can successfully flash firmware.

How to Downgrade from Pie Beta to Oreo ?

Is there any ways i could downgrade my S8 from Pie Beta to Oreo - I Would Love to know that & My Model is G950F
find the latest oreo firmware for your model/country and flash it with odin
Just to confirm that data will be wiped if we flash with odin even using home csc file?

Last time I was on Beta (8.0) you could go back using Samsungs Kies.
It flashed latest available firmware on your phone.

"10. How can I restore the official software during the Beta Programme?
You can re-install the official software by using the PC version of Smart Switch.
(You can download it from the following link - http://www.samsung.com/uk/getting-started/smart-switch/).
Please connect your phone to your computer, launch Smart Switch on your computer, and press the “Update” button to re-install the official software (rollback). "

I just downgraded back to Oreo from DRL5 Pie build last night. I Odin back to CRK1. From here you can stay or update to latest Oreo build. After I flashed CRK1, I did have to go into recovery and wipe data/factory reset. It will just remove everything from your phone to factory defaults. Make sure you remember your google login details or you could get locked out of your phone. And back up your photos and stuff. I'm on sprint s8+.
