I've tried Sony's instructions but when I run fastboot, I get this error:
Code:
FAILED (remote: Command not allowed)
This is the command I run:
Code:
fastboot -i 0x0fce oem unlock 0x0
I removed the last part on purpose.

Have you turned off/disabled my Xperia and enabled the oem unlock in the developer options.
Sent from my Xperia XA using XDA Labs
May I ask you (or anyone else !) what device to chose in Sony's devices list ?
I don't see Xperia XZ.
Or it doesn't matter ?
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?

Model: MHA-AL00
Build: MHA-AL00C00B213

...
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:
tohc1 said:
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.
