No. Only the "fastboot oem lock" command will lock your bootloader.

Error while unlocking bootloader

Hi !
I want to unlock my bootloader so I follow the instructions from the Sony's website. When I have to use the follow command : "fastboot -i 0x0fce oem unlock unlockcode" I have the following error :
Code:
FAILED (remote: Command not allowed)
This error is under Linux Mint. I try into Windows 10 and the fastboot devices return nothing..
I also check if the bootloader can be unlocked, and it is !
Any help ?
Thanks a lot !

Try unlock bootloader via Flashtool. It worked for me. Maybe you have to request a new code from Sony.

OEM unlock not appearing in developer options.

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.

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"

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.
By the way, you dont happen to use Linux?

Unfortunately, because of the FRP lock, is what is causing the commands to fail.
Were you doing anything prior to trying to unlock the bootloader?
What model do you have?

MHA-L09C02 but is rebranded to mha-l29c432b363. I close the bootloader because i flash xposed and the phone entered to bootloop, I could have closed it but now I can not open it.

Have you solve it? Unfortunatelly i have the same issue:crying:

Yeah, seems xposed causes this type of issue for everyone I've heard who tries to install it.

If using windows, make sure you are using command prompt in administrator mode. If using linux, use sudo fastboot ******
Just a thought

I would say either you're trying to reboot to bootloader (adb reboot bootloader) with the phone on and not in storage mode and without debug on...
Or you're in bootloader and it's already locked.
Other than that, I'm clueless.
