UPDATE (14TH FEB 2018): Samsung has pulled XXU1CRAP from SamFirm and FOTA as they discovered some bugs with the update. They are working on a new update that will be pushed out soon hopefully. For now, thanks to @itskapil he has made mirrors for the S8+ ROMs, that don't require the modification in the guide given below:

S8 G950F / G950FD (F ROMs work on the FD variants, there are no FD specific ROMs):
Mirror Link 1
Mirror Link 2

Let me start of by saying, Samsung changed some things around with Oreo. I downloaded 'XXU1CRAP' using SamFirm today, tried with both TUR and DBT CSCs, to make sure it wasn't a bad download or anything, but Odin just wouldn't accept the file. It froze on the first step, sboot.bin.lz4.

I had never seen the .lz4 extension before, so I asked a couple of helpful lads in the Samsung Oreo Telegram group who were very helpful throughout this process.
For those of you who want to join:

Samsung is using a new compression method for the Oreo ROMs, so all files within BL, AP, CP and CSC have the .lz4 extension which Odin has trouble reading, and so the flash will never go past the first step.

Note: THIS DOESN'T TRIP KNOX.

Pre-requisites:
-SamFirm to get the CRAP ROM - https://forum.xda-developers.com/gal...mware-t2988647
-Windows PC
-This modded version of 7Zip which can open .lz4 files. Link - Github
-The ability to read the instructions below.
-Prince Comsy's modified Odin - Google Drive Link
-A Galaxy S8/S8+ (G950F / G950FD / G955F / G955FD) - I tested this on my own G955FD and it worked just fine.
-The XXU1CRAP Oreo ROM for your device
-A decent amount of storage space on your PC
-Preferably some experience with flashing using Odin

DISCLAIMER: I AM NOT RESPONSIBLE FOR BRICKED DEVICES, FOLLOW TUTORIAL AT YOUR OWN RISK.
INTERNAL STORAGE WILL BE COMPLETELY WIPED CLEAN (IF YOU USE CSC_OXM), MAKE SURE YOU BACKUP BEFORE FLASHING.


Steps below:

1. Extract the zip file for the 3.7 GB firmware file you just downloaded. Should contain 5 files, AP, BL, CP, CSC_OXM and HOME_CSC_OXM.
In the tutorial below, I will be using CSC_OXM, however that does wipe internal storage.
If you are coming from ZRA5 or just don't want to wipe your data, use HOME_CSC_OXM instead.

2. All the files will have ".tar.md5" extensions. Remove the .md5 part so they can be opened in either WinRAR or 7Zip.
AP will contain a folder called 'meta-data', userdata.img.lz4, system.img.lz4, recovery.img, boot.img.lz4
Extract all these files from AP into a new folder. Right click on each one, select the '7Zip Standard' menu and hit 'Extract Here'.
This will extract all the files within, without .lz4 extensions. So you'll have userdata, system, recovery and boot as plain IMG files.
Note: Repeat this for CP, BL and CSC_OXM.


3. Grab the original file names for the files you extracted earlier, copy paste them into notepad.
They should be in this format, make sure .md5 isn't added at the end of any filenames. Do keep in mind that the filenames for the S8 (G950F) will obviously be slightly different.

Code:
AP_G955FXXU1CRAP_CL12993656_QB16754780_REV00_user_low_ship_meta.tar
BL_G955FXXU1CRAP_CL12993656_QB16754780_REV00_user_low_ship.tar
CP_G955FXXU1CRAP_CP8821296_CL12993656_QB16754780_REV00_user_low_ship.tar
CSC_OXM_G955FOXM1CRAP_CL12993656_QB16754780_REV00_user_low_ship.tar
4. Select all the files you extracted for AP (including the meta-data folder), right click, scroll down to the '7Zip Standard' menu again and this time hit 'Add to Archive'. Copy-paste the filename for whichever file you're creating an archive for, AP, BL, CP or CSC, make sure archive format is set to .tar and leave everything else default and hit 'OK' at the bottom of the window.
Note: This too will be have to be done for CP, CSC and BL as well.

5. Once this is done, you should have 4 .tar files ready to be flashed. Open up Prince Comsy's Odin, add each file to it's respective field in Odin.

6. Connect your device in Download Mode, press Start, and wait for the flash to be completed and for Odin to show 'PASS' at the top of the window.
Your device will reboot automatically.

ALTERNATIVELY, you can watch this very crappy screen recording I made for a better idea on how to do it.

It works perfectly!, finally I have Oreo from a clean installation



I uploaded the files with the extraction process done (.lz4) in Google Drive but I can not publish it because I'm new, If someone wants it, you can ask for it through PM.

Did anyone try with HOME_CSC? I'm currently in ZTO (brazil) CSC and I would like to flash without wiping data and still have access to Samsung Pay. Does it work?
