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...

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

FRP - Factory reset protection ie:google accounts
KG/RMM states - another lock by sansung to prevent modify phone ( been around since early oreo )

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.

Hello,
I have a Samsung Galaxy S7 edge ( SM-G935F ) Exynos Version.
I flashed the new Oreo Firmware with Odin. I have also a Samsung Gear 3 and wanted to use SHealth. I rooted the device ( didnt work) .
I set back the OEM setting in the Developer Options and turned off USB-Debugging. After restarting I got an ERROR: Custom binary blocked by FRP Lock.
I deleted my Data : "Wipe data/factory reset" in the Android Recovery
Now my Problem: I cannot flash the Stock Firmware again and i cannot flash TWRP.
So I think i dont have Android and i also dont have enabled the options OEM & USB-Debugging.
Has anyone an Idea what to do?

So you have disabled oem unlock and you can't flash custom rom or recovery due to custom binary blocked by frp error..
Also you can't flash stock rom due to dm verity error if i guessed correctly?
You are badly stuck... maybe follow this thread it may help https://forum.xda-developers.com/galaxy-s7/how-to/guide-onelatest-stock-fw-csc-root-t3702963/

I have this S7 Edge Verizon which a few days ago gave me a problem. I was using the phone just for a few days.While using it, social media normal stuff it self restarted ( notice that it was pretty hot, but it's a usual thing at this point ) and it got stuck in logo.
P.S: I am really familiar with this kinda stuff because I work at a phone service.
So I tried the usual stuff, wiping cache and data but it didn't solve any thing. So I decided to flash official rom. I downloaded the oreo rom from sammobile and when I tried to flash it, it just skipped all files. I thought this would be due the verizon model, because it's bootloader was locked and oem unlock wasn't enabled. I tried to flash the firmware without the bootloader and with pit but no result. Than I decided to enable oem unlock throught combination file.
When I downloaded combination file, at the website it said G935V but it actually was G935A, and somehow it flashed successfully without any problems. But after reset the phone was stuck at the very first Samsung Logo with some cpu and voltage information at the top left corner with a warning saying RPMB provisioned.
At this point I thought I might as well flash the stock firmware again but this time I got bootloader error and trying to flash it without a bootloader it would skip all files saying something like " skipping all binary files " as before. Bare in mind that during all this testing the phone got really heated. So I let it cool for a while and still nothing happened. Than I decided to flash this boot_root file I found and it actually booted up the Combination Rom. I enabled usb debugging in the settings but there was no Oem Unlock option, not even grayed out ( maybe because the rom G935A does not have the option ).
Even the USB debug enabled it still couldn't flash stock rom because of bootloader error and some binary error also and again if i didn't include bootloader it would skip all files.
I was thinking of installing a custom rom but I found out that there is not twrp avaible for s7 edge verizon because of it's locked bootloader. And if I try to install supersu through adb it just doesn't work.
Now my download section looks like this
ODIN MODE (HIGH SPEED)
PRODUCT NAME: SM-G935A
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Custom
FRP LOCK: ON (don't worrie about it, i got all the gmail info)
WARRANTY VOID: 0x0 (the warranty has expired anyways)
QUALCOMM SECUREBOOT: ENABLE
RP SWREV: B5(2, 1, 1, 1, 1 ) K1 S4
SECURE BOOT: ENABLE
IDOQ : G(42), S(12) mA
CPU SERIAL NUM : 0x1408501f
Fused open loop voltage: 970mV
RPMB PROVISIONED
The Samsung first boot up screen still has the RPMB PROVISIONED with the cpu information and also the custom flagg and I am able to boot up the combination rom.
I also tried to flash the official rom with z3x but it didn't solve anything. If you need any additional information just tell me. Any help would be greatly appreciated.
You need to download official firmware from another source. I recommend updato.com.
https://updato.com/firmware-archive-select-model?record=4F3A1B13706611E89F15FA163EE8F90B
You need to flash the latest Oreo firmware for the Verizon SM-G935V because it sounds like your phone has issues with your current bootloader. Go back to the Verizon firmware first and see if the phone works normally. Also, flash the regular CSC file not CSC_HOME.

Do you recieve the "Only Official released binaries are allowed to be flashed" error in Download mode? Or do you get the error at boot up? If its just in download mode and you can boot up then enable OEM unlocking in developer options and wait 7 days (Connected to the internet without reboots). Then RMM state: Prenormal will clear and you will be able to flash anything you want. (root, TWRP, etc.)
If you get the error on boot then you have to try different stock firmware until one flashes, I found this thread about a solution to this same problem: https://forum.xda-developers.com/ga...lashed-rmm-prenormal-oem-locked-t3805049/amp/
Once you can boot up normally do what I said above for unlocking the bootloader and clearing RMM state: Prenormal. Then, you will be able to flash TWRP, root etc.

The official release are allowed to be flashed error means you are flashing non samsung firmware ( ie: twrp ) due to bootloader not being fully unlocked ( OEM unlock + KG/RMM states )

To flash non stock firmware you will need
System - OEM unlocked in Developers menu
In Download ( odin ) mode you will need
FRP - OFF
OEM - OFF
RMM status - normal ( or disappeared ) - ( depends on current android version )
KG status - checking
Then you can flash twrp, root etc
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.
