Bricked S8, have tried multiple solutions

I successfully rooted my phone but it got stuck in a bootloop when I restarted it.
I can't enter recovery mode or turn it off, all I can do is enter odin mode.
I have tried:
1. The AGQ5 fix (https://forum.xda-developers.com/ga...g-aqg5-fix-t3636857/post73032395#post73032395) it doesn't work.
2. Smart switch, it says my device is unsupported
Please help!

1- flash twrp again
2- flash stock rom with odin ( download mode )
you can reboot just with vol - + shut down B

you maybe installed the wrong version of twrp the latest one is for the new bootloader if you have the older bootloader install the last version

It doesn't boot into TWRP even after I flash it again

Sorry if I'm asking a question but how do I check my bootloader version? I just used the latest version (twrp-3.1.1-0-herolte.img.tar) from a site but I can't link it.

Flash full stock in odin. Then you can try twrp again if you wish.

It worked, thanks so much for all your help. Words cannot describe how grateful I am.

smt-580 locked on chinese firmware (bootloader release 5)

Hello,
On my SM-T580 (TAB-A wifi) I flashed the last official rom with odin : PDA : T580ZCU5CSF1 / CSC : T580CHN5CSF1
2019-08-23 Release 8.1.0 T580ZCU5CSF1.
The flash went well but the tablet doesn't start anymore (black screen when switching on).
when I start in "download" mode, I get the download screen in chinese ...
However it is absolutely impossible for me to flash any other official ROM.
the flash starts and then goes to fail immediately with an error message in chinese "Bootloader locked".
the message on the tablet is: SW REV. Check fail ( bootloader) Device:5, Binary: 4.
I understand that the bootloader is now in release 5 and that all other ROMs are in 4 maximum. So it doesn't seem possible to downgrade my tablet and install an official (or unofficial) rom.
It seems to me that there is no solution as long as Samsung will not develop a functional ROM with a bootloader in release 5.
Do you have a solution for a possible downgrad or to make my tablet work ?
I also tried to flash a sm-t585 bootloader with a version 5 bootloader but without success.

Hi, did you found a solution? I did the same , and I have the same problem, the only difference is that I'm able to use my tablet, I flashed the last chinese firmware from march, its functional but with no google services.

The only way to bypass a locked bootloader/downgrade your bootloader is to buy a JTAG/Riff/Octoplus box and write the firmware you want to flash directly to the board.

Hi I have the same problem,
I was looking on Sam firmware for latest firmware and saw firmware for last month for my t580
Problem was it was Chinese, I thought just change the language during setup right? And then after I oem unlock and enable adb I can flash TWRP then root.
HOW WRONG WAS I?
The problem is the firmware for the t580 in China has bootloader locked.
Not only that, the bootloader has been updated to recent firmware and the btu (UK) and other firmwares only have a patch 6months prior.
So I am screwed unless the other countries update to a later security patch so I can pass the SW rev check and unlock bootloader again.
Just so noone else tries this as it's a PIA
#####EDIT ##### To solve this problem let the tablet boot up with the error code, connect to odin and flash the Chinese firmware again, then download and install crom service apk, goto developer options and do the usual, adb enable, oem unlock. Open the crom service app and select OK/Off whatever and reboot to download mode...
Once reboot to download mode and you will see crom service off and will be able to flash twrp, roms etc again.

Looks like judging from your screen shots
1. You are trying to flash F firmware onto a U device. Exynos to snapdragon. Will cause you issues.
2. You will need Odin ( or patched Odin ) 3.13.1 or higher
3. You will need a binary ( bootloader ) version 5 or higher.

Just download latest firmware from sammobile

There are many guides on the internet regarding to phone authentication and about refurbished phones.
On your S8, since it doesn't have a removable battery, on the back, down the bottom, should show model no. etc. engraved on it ( not stickers ).
On the back it will also show iIMEI + serial number. Compare it to what it say's on the phone ( about phone + *#06# ) to the back engraving.
There are websites that can check your IMEI number to give you various information about the phone.
Buying a phone from the internet ( eg: eBay etc.) using the IMEI can be used as a way to check the phone.

i just got one more device from a local store , it's not official retailer of samsung , its from a paralel imports
and its the same ****
firmware box and stickers say SM-G950F
recovery say SM-G950U, i didn't tried to flush because i cant get the OEM unlock.
BTW is it possible to downgrade this device to android 8 ?
image uploader

so if i understood right i should be able to flush this firmware on this phone
G950USQU5CRL2
?

In download mode it will have a line with PR SWREV
The number after the B is your binary ( bootloader ) number.You will need to flash this number or higher. You can not downgrade binary numbers.
Depending on what firmware you flash U or U1 you may need patched Odin.

Binary ( bootloader ) is the 5th number from the right of the firmware ( in the above post it's 7 )
e.g.:G950USQU5CRL2 - 5 is the binary number.
The letters/numbers after the binary number will tell you version ( security patch ) issue information but is easier to check the date of the firmware from the website you are downloading from.

thank you @spawnlives i really appreciate this

Can I root my s8 with TWRP?

I got a Galaxy S8 G950F with Android 9 ( G950FXXUCDUD1 ).
Can i simply Root this device by Flashing TWRP via Odin ?? ( OEM Bootload unlocked surely ) or will i get problems with this android version ??
I read something about problems with rooting the s8 on Android9...
What about that?

Yes
As long as the following conditions apply:
OEM unlocked in developers menu
In Download ( odin ) mode:
FRP off
OEM off
KG status - Checking
Probably not on this version but if you have RMM state should show normal or disappeared
Then you can root your phone with either twrp or patched method

What is FRP, KG status, RMM State??
Never heard of this things before

Ahh okay .... i think FRP is that what makes trouble when u factory resetting a used phone ...
When i boot into DL-mode it shows me:
Current Binary : samsung official
FRP lock: off
OEM lock: off
Secure Download: Enabled
and three brown" lines and 17 Green lines ... but nothing about KG-Status or something with RMM_state ....
So flashing TWRP via Odin with this settings will work?
( but better using the TWRP Flashing after Oreo guide with 1 or 2 extra flashing files and SU , right ?? Or just only actuall TWRP Version via odin and finish? )

In regards to FRP question basically yes.
Did you have internet connected while in the system. On this version ( G950FXXUCDUD1 ) you will only have to worry about KG status. If it's not showing up your can try to flash twrp. I would keep a copy of your firmware in case you end up with ' only official binary crap ' error. This usually means bootloader is not fully unlocked.
Using guides for installing twrp ( only ) are still valid but some files are either updated, not necessary or have change but the method is the same.
Depending on what twrp version you use will depend on the no-verity zip required. This is basically all you need to install twrp.
I'm using the latest twrp version and use this no-verity zip. You will have to and ' quota ' the zip file name.

Twrp recovery error

Each time i try to flash TWRP recovery on my galaxy s8 i keep getting this error
only official binaries are allowed to be flashed(recovery) twrp it's the 950f model

Flash stock firmware to fix.
Make sure OEM is unlocked in developers options.
In download mode make sure KG/RMM state is showing checking/normal
Also make sure FRP is off.

What kind of stock firmware?

Rmm sate: prenormal is this ok?

Stock firmware can be downloaded from websites like updato, sammobil etc.
Or search on XDA for PC app called frija. It will download latest firmware.
If RMM state showed prrenormal you can't flash twrp, root etc. Has to be normal or disappeared from download mode.
