Galaxy S8 Stuck on "Powered by Android" Screen After Android 9 Update. - Samsung Galaxy S8 Questions and Answers

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] #

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:

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.

Connect your phone to computer. Install Samsung Smart Switch on the computer and initiate a firnware reflash trough it. It is official samsung service so it will automatically download the latest official firmware for your device and after that it will flash it no matter what you have done to your phone as long as you can boot it into Download Mode.

Device 4 Binary 3 means you are flashing older firmware than what is currently on your phone. You will need to get latest firmware with bootloader 4.
Bootloader version number is the 5th number from the right of the firmware name. The same error will happen if you use combination firmware as well.

[Solved] How to find recovery installed ??

Hi
I have a Samsung Galaxy Note 3 (SM-N9005) flashed in Cyanogenmod ages ago. I'd like to reflash it with a new more recent ROM*as right now in CyanogenMod phone is more or less in a bootloop (most of time rebooting just few seconds/minutes after having finished the boot).
Unhappy I'm unable to find out which recovery was installed. I tried to keep physical Vol+ or Vol- butoon pushed while booting but it makes nothing. At boot I just get briefly displayed:
HTML:
Kernel is not SEandroid enforcing
Set Warranty bit: kernel
Is it safe to flash it with TWRP considering it as still a fresh device with original rom ? or danger ?
Thanks
You are booting to download mode try recovery mode.
Vol + Home button and power button
Vol- Home button +power button
As it does not have original firmware .
I would flash latest stock rom through Odin then flash required TWRP.

Well it had at first but as Samsung very quickly stopped any updates I had switched it to CyanogenMod. I have succeeded to install on it the latest TWRP: 2.6.3.7 but each time I try to flash a ROM*(tried with two different ROm just to be sure)*I get the same errors in TWRP. For info files to flash on the SD*Card.
Code:
Updating partition details....
E:Unable to mount '/usbstorage'
Installing '/external_sd/lineage-16.0-20181010-
Checking for MD5*file...
Skipping MD5 check: no MD5*file found

E: unknown command [log]
E:Error executing updater binary in zip '/exter
Error flashing zip '/external_sd/lineage-16.0-2
Updating partition details...
E:Unable to mount '/usbstorage'
I double-checked on original sticker for manufacturer on device and it's well labelled as SM-N9005 so it's the HTLE version no ?
Update: I have tested with a ROM with Android 7.1.2 in it and install in twrp is going fine including gapps but at reboot it get stuck on Samsung Galaxy Note 3 and that's it and it's indicated at top of screen in yellow: Set Warranty bit: kernel
Not sure what's the problem there ?
Thanks for help,
Vincèn
and that's it and it's indicated at top of screen in yellow: Set Warranty bit: kernel
Correct unless its all stock kernel rom and recovery .
:Error executing updater binary in zip '/exter
