I cant seem to find the unlock OEM option at all in the developer options. I tried to add images to show my problems but was not allowed to....sigh. Either way I cannot see the OEM option in my phone.
Model: MHA-AL00
Build: MHA-AL00C00B156
This is what I get after flashing TWRP with no issues and trying to reboot into recovery.
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot boot TWRP.img
downloading 'boot.img'...
OKAY [ 0.464s]
booting...
FAILED (remote: Command not allowed)
finished. total time: 0.471s
Any help would be greatly appreciated.
Chinese firmware doesn't have oem unlock option.
Did you unlock bootloader?

Yes I did. I can't seem to figure out what to do next. It shows to me that the twrp recovery has been installed but when i go to it it comes up with the recovery from the huawei. So i can't flash anything.
So if it doesn't have the OEM option to unlock can I not install recovery or root the handset?
Without the phone plugged,hold volume up and power till u see the logo, release power while keeping volume up pressed.
try this
shut down phone
press vol up + power
when saw the huawei logo
release all buttons
wait
done
u r in twrp

fastboot boot is not supported. try the keys combination
Fastboot boot twrp.img would not flash twrp, what it tries is downloading twrp.img then boot it without flashing.
I'm not sure how it is for the Chinese Mate 9s, but you'd want 'fastboot flash recovery twrp.img', that flashes twrp (if your twrp is named twrp.img).
If it says it flashed twrp, try 'adb reboot recovery'.
Never flash recovery to boot partition.
For recovery : "fastboot flash recovery twrp.img"

Were you able to unlock the bootloader of your Mate 9, MHA-AL00?
In my Developer Options there is no "OEM Unlocking"
Model: MHA-AL00
Build: MHA-AL00C00B213
I've been trying for days and I can not because the error always appears:
...
FAILED (remote: command not allowed)
Finished. Total time: 0.031s.

Are you using "fastboot flash recovery twrp.img" or "fastboot boot twrp.img"? The boot command is not allowed.

I'm still trying to unlock the bootloader using the command prompt and ADB and Fastboot, after I got the Huawei code:
Step-1: Open the command prompt and enter the following command.
Adb reboot bootloader
Step-2: Your phone will reboot and enter into bootloader mode.
Step-3: Now enter the following command to finally unlock the bootloader.
Fastboot oem unlock xxxxxxxxxxxxxxxxxxxx
And it always fails.
I do not know how to use "fastboot flash recovery twrp.img" or "fastboot boot twrp.img".
Do you have a guide how should I do it?

But he says it fails every time.
@tigrelouco
Open a terminal or adb shell and enter these commands:
getprop sys.oem_unlock_allowed
getprop ro.oem_unlock_supported
And post results.
Found this in another thread:

To answer my own problem/ for anyone else having problems it is necessary to remove the factory reset protection (frp) to do this you need to remove all pin/password/fingerprint locks, then remove all google accounts and finally do a factory reset.
Then the usual adb/fastboot commands work fine.
As linux33it says the bootloader can be unlocked without the option in the developer options.

Download Terminal emulator from the playstore or use adb from command prompt.
By the way, you dont happen to use Linux?
I have a Nokia 6.2 with bootloader unlocked..
I flashed phone with Nokia-Tool. All working fine..
I wanted to lock bootloader and used command: "fastboot flashing lock" before "lock_critical"
Phone then rebooted into fastboot and is stuck there. No matter what i do, it returns to fastboot mode, except if i choose Power Off. Then it shuts down.. If i try recovery, it reboots into fastboot again.
If i try "fastboot flashing unlock" it returns
" FAILED (remote: 'unknown command')
fastboot: error: Command failed "
I have also tried "fastboot oem-unlock "
When i check status.
"fastboot flashing get_unlock_ability" returns. "(bootloader) get_unlock_ability: 1"
I did not use "fastboot flashing lock_critical" before lock bootloader. So unlock_critical is still open.
Is there a command to unlock bootloader again? Or am i using wrong commands ?
Hello bro same thing happened with me in my 7.2. do you have any solution?
Hello,
I'm trying to unlock the bootloader on my Oppo A 15 with ColorOS 7.
The developper mode, debugger usb and oem unlock are enabled.
I use the last adb fastboot platform tools.
I reboot my phone on recovery mode (there's no fastboot, or download mode or whatever), I then have a very short menu on my phone.
On my computer, fastboot detect the fastboot device but then, unlocking bootloader doesn't work.
Fastboot fastboot flashing unlock return the message "unable to open fastboot HAL"
There's not much I can do as a matter of fact. I tried several of the command In Here and most don't work.
The command "fastboot getvar all" gave me a sh...load of informations, but I don't know what I can do with it.
Any help?
Hey all,
Trying to unlock Bootloader on Doogee X95. I've managed to get as far as selecting yes to unlock bootloader from fastboot mode however it fails. When pressing vol up it says "unlock failed" with no further reason then returns to fastboot menu.
In the cmd window the following was printed:
fastboot flashing unlock
<bootloader> start unlock flow
FAILED (remote: '
Unlock operation is not allowed
'>
fastboot: error: Command failed
Any ideas on what might be going on? Is this just one of those phones that do not allow for bootloader to be unlocked?
I've accidentally rebooted into fastboot mode menu rather than bootloader once and the info on bootloader it had was:
Bootloader version - Unknown
Trying to see if I can flash full/original android onto it to replace android go it has from manufacturer to open display over apps feature.
