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: 1. Registered a Huawei account, and got my access code 2. Turned on USB debugging 3. Connected my phone and computer with a charging cable 4. Ran adb and fastboot 5. 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?
