Bootloader unlock failure "Command not allowed" of a Huawei Honor 6x I have followed all instructions to unlock my Huawei bootloader, until the last instruction in the command prompt.

Some maybe useful information:


My computer runs windows 10
My phone is a Huawei Honor 6x (title)
I am using a charging cable to connect my phone to my computer


What I did so far:


Registered a Huawei account, and got my access code
Turned on USB debugging
Connected my phone and computer with a charging cable
Ran adb and fastboot
Opened Windows Powershell (I couldn't find command in the adb folder) and typed the following commands:


adb reboot bootlader
fastboot oem unlock 2**************1



It produces an error message that says:


Also, my phone should say "unlocked", but it still says "locked".

Any ideas on why the command is not allowed?
It is because Huawei has completely terminate the unlock code application service on July 25th, 2018.
You can refer to the following link where Huawei has officially mentioned it.
