SM-G290F bootloader problem

Hello I have S6 sm-g920f on 5.1.1 ,I was trying to flash engineering bootloader with odin but it always fails on flashing sboot.bin...I downloaded stock 5.1.1 firmware to reflash it fails again on flashing sboot.bin...I was curious to see if I can do something with kies3 so I installed it and went to emergency firmware recovery no devices in the list but it has an option about an emergency recovery code witch I dont even know...Anyone experiencing something like that ?
Thanks in advance
PS no oem unlock option in developer options.

Unable to flash recovery

So, I'm on B513 downgraded from B571 through a TWRP backup. I want to downgrade to Lollipop because I don't have WiFi nor BT.
My plan is to downgrade to Lollipop and then upgrade to Marshmallow to see if I get wireless connectivity back. I'm going to change my MT7-L09 vendor country info to Africa/Middle East because I've researched that these regions' firmwares have WiFi and BT enabled.
And here comes the problem: I can't flash any recovery via fastboot cause I get
Code:
FAILED (remote: command not allowed)
I found that my bootloader might be locked, even though in FASTBOOT&RESCUE mode says that it's unlocked. I've tried to re-unlock my Mate 7, but the site where I can obtain the unlocking password is broken. Currently, I don't have any recovery installed. I've tried Flashify, Rashr, etc.; with no avail.
Can anyone help?

On which flashtool you install twrp?
And your fastboot is unlock or nor?
With twrp you wipe which partition

Hello,
Greyed out OEM Unlock option can means "already unlocked" or simply not available for this region (firmware region?) and/or network carrier...

Do not forget that your need to unlock your bootloader first via fastboot unlock command (using the unlock code for your device).
Then flashing TWRP on Oreo is not the same command as previous android versions AND you need TWRP "EMUI 8.0" compatible version.
New fastboot command:
Code:
fastboot flash recovery_ramdisk twrp-filename.img
And below, I give you 3 TWRP versions that shoud work for Honor 8 EMUI 8.0 (Oreo) devices:
1) Official latest TWRP version: twrp-3.2.2-0-frd.img
2) Previous version (found in "Huawei Multi-Tool by Team MT" v8): FRD_TWRP_3.2.0_EMUI8.img
3) Modded TWRP version (found in "Huawei Multi-Tool by Team MT" v8): FRD_TWRP_S_mak_KV_v2_EMUI8.img

apparently the Russian firmware does not allow the unlock of the OEM. I think maybe there are no solutions. I do not know how to make a rebrand with oem and boot stuck.

Before frp was unlock but when i doing factory reset again frp and oem both lock

The Russian variant allows unlocking, you can't block this. It's illegal, even there. You need to unlock your bootloader. It's that simple. I do not care if you did it before, you need to do it again since you flashed firmware.

MHA-L29 stuck at 'Your device has been unlocked and can't be trusted'

Hello,
I have Huawei Mate 9 (MHA-L29) and it's stuck at 'Your device has been unlocked and can't be trusted'.
I read many threads on xda and they all suggest different suggestions.
More info about phone:
Bootloader unlocked
Fastboot says Phone Unlocked FRP locked
Model: MHA-L29
Firmware ver.: MHA-L29 8.0.0.321(C432log
SN: AHK0217222004122
What I already tried:
Flashing TWRP via fastboot; FAILED (remote: Command not allowed)
Flashing firmware via force method (UPDATE.app in dload folder on SD Card)
I wanted to relock bootloader but I can't get the code since official huawei site doesn't have request code anymore (correct me if I am wrong), DC Unlocker can't recognize phone in fastboot mode so I am unable to buy code. (Is there a way to get bootloader code?)
Did ayone else have same problem, what should I do?

The only thing I can think of is that you flash rom board and being there you can get the code with HCU, once obtained go back to where you were before
