The FE forum has few visitors and it's a 7 so I hope this is OK.
Dev mode was on but not OEM whatever that is, or debugging, don't think. Never done any of that so not sure what's important.
It died overnight somehow, thought maybe an update but wasn't.
Would not boot past the small Samsung logo.
2 Photos of recovery mode and what it says.
~~~~~~~~~~
#fail to open recovery-cause(No such file or directory)#
#Reboot Recovery Cause is [UNKNOWN]#
No Support SINGLE-SKU
File-Based OTA
Supported API: 3
# MANUAL MODE v1.0.0#
Successfully verified dmverity hash tree
E:Failed to clear BCB message: failed to find /misc partition
Recovery mode has the firmware and on 8.0.0
~~~~~~~~~~
I cleared cache and nothing changed.
Before I try to factory reset it, any advice?
Should I try to install the same software overtop? How to do it?
Or I would have to wait for an OTA update? Does a security update count? Do you think we'll see one soon that helps?
If a factory reset, my sd card data is kept, I assume, but what about any data on the main disc partition? Zapped into netherworld? Not sure what's kept there I might need. Moved photos already to sd.
Thank you.
I got the same issue, hope someone can help
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.

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?

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:

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.

Hello Everyone!
I have the same problem with Galaxy Note 8 / SM-N950F
Is there a solution for this??
Please need help, please please.
Thank you
Was trying to get this phone rooted and backdate the OS to 7.0 and wiped the NAND in hopes that it would clear the 8.0 ver 5 boot loader. Now what, is it completely soft bricked? I can load the firmware but it sticks in a boot loop on the recovery update!

Just Odin a newer firmware and your phone should be fixed
I tried that already and it's stuck in recovery loop...
More details may help...
The phone starts to boot into recovery, then says "installing sys update" then splashes...
"#fail to open recovery_cause(no such file or file or directory)#
#Reboot Recovery Cause is [UNKNOWN]#
No Support SINGLE-SKU
File-Based OTA
Supported API: 3
dm-verity verification failed...
E:failed to mount /cache (invalid argument)"
then it loops back into recovery.

Do you have the right firmware? What is your device...G 930p? The modded Odin? Also, maybe redownload the firmware file again.

Yes it's the right firmware, correct it's a SM-G930P. Didn't know the modded Odin made a difference, I've tried both versions of Odin...
When I flash the firmware now it fails during the "boot" part of the firmware upload.
Well, turns out it might have just been a garbage USB cable! Got the phone reflashed, but now there's a NEW PROBLEM! Phone boots now but I go through the WiFi and agreement boxes... But as soon as it does that and chews on the next "welcome! preparing your device for first time use... This may take 3-4 minutes" it then just reboots continuously back to that screen!
Tried two different firmware images and it does the same thing!
NM I got it figured out, used the WRONG home file! Derp!

Hello. I have problem with my SM-530F (2017). Lately, I've tried to flash TWRP in ODIN, but failed. Phone went in some sort in loop, where Samsung logo is visible, then everything is black, and Samsung logo again. I have installed new BL, AP, CP and CSC, but it didn't resolve that problem. In recovery there are lines with this messages:
#fail to open recovery_cause(No such file or directory)#
#Reboot Recovery Cause is [UNKNOWN]#
No Support SINGLE-SKU
File-Based OTA
Supported API: 3
E:unknown volume for path [/odm]

dm-verity verification failed...
E:Failed to clear BCB message: failed to open /dev/block/platform/13540000.dwmmc0/by-name/MISC: No such file or directory
Is there any way to fix it?
Thanks in advance.
