HELP!!! Stuck in Samsung Logo

Hi, I have a S8+ and I'm having a BIG problem. I tried to put the stock ROM in my S8+, and now it shows the message: failed to mount /efs (invalid argument) in recovery after reboot, after odin says "PASS"... So I select the option "Reboot System Now", and Samsung Logo appear and nothing happens after this. Stuck!
I have OEM Locked and can't enter in the OS... Help!
Once when I had TWRP I backup my EFS. I have this archives, but I don't know how to zip then to Flash in Odin... (look at attach files).
Help!!!

Try downloading firmware from your region, for the exact same model of your phone.

Galaxy S8 Stuck on "Powered by Android" Screen After Android 9 Update.

Hi guys I own an S8, SM-G950F. The previous software I was on was Android 8 U2 (can't remember exact one). I flashed the new DBT Android 9 software via ODIN (using CSC, not home CSC). However the phone stays in the "Powered by Android" screen and does not go any further.
I can go into the Samsung recovery mode and have tried wiping both the cache and data/factory reset but this seems to make no difference. As an alternative I have tried flashing the Android 8 files (with bootloader U4), which is successful in ODIN but shows "No command" when booting.
USB debugging was also turned on before applying this update.
Other info:
FRP Lock: Off
OEM Lock: Off
RP SWREV: B:4 K:3 S:3
Any ideas what I could do?
Thanks.

Thanks for your reply. I have tried this although it does not work as the boot loader version is now at V4, whereas the previous software I had was V2. I have tried flashing other Android 8 software with boot loader V4 but it goes into the “No command” state where I can’t access the recovery, only download mode is available.

Also a little more info. When the ODIN flash is successful it restarts to the "Install Software Update" blue screen. It reaches 32% but then begins erasing.
The following error message is also present in the recovery:
#fail to open recovery_cause (No such file or directory) #
#report recovery cause is [unknown] #
Support single-sku

I also am seeing the same message in recovery mode. Also in odin mode(download mode) there is extra lines of text. Although in saying this the s8 boots and seems to function as per usual. The storage used from stock firmware is 12.4 GB... Is this normal??
All I am wanting to know is "is this normal for the exynos galaxy s8 running One UI, android 9" ?
or Did I Download a dodgy Rom?

Did you arrive to any conclusion?
Hey I have the same problem as well... I can't flash twrp because I have oem locked and I can't boot into my because it keeps restarting and getting stuck at some point, and the recovery is saying:
#fail to open recovery_cause (No such file or directory) #
#report recovery cause is [unknown] #

File-Based OTA

How can I fix this?
Is there any update on this? I have the same issue as post #11 on a Samsung A8 sm-a530w.
Any help would be much appreciated.
I've got the same issue on a G950F.
I bought new (sealed, G950FXXU5DSFB), and tried to flash combination file G950FXXU5ASF1 . This did not work. (no boot).
So I flashed what I thought was stock rom matching CSC.
(AP_G950FXXU5DSFB_CL16290088_QB24491245_REV00_user_low_ship_meta_OS9.tar )
The phone boots and operates fine, except for the same message you guys are getting in recovery, as well as a message about no OTA updates.
