Hello everyone, I'm new in the Android world.
I have been trying to unlock my bootloader with the sticky guide, but it doesnt work for some reason.
In the cmd (after i got into the "Device locked" screen) it gives me an error and i dont know how to fix it.
I would like to see a full working 2k17 guide for how to unlock bootloader for a Huawei P7 running android 5.1.1 with Emui 3.1
Hope someone can help me.

What guide do you use?
Did you install your driver (HiSuite)

Before you are flashing try the command "fastboot devices". Is your devices listed?

I used this guide: https://forum.xda-developers.com/ascend-p7/general/rooted-p7-l10-609-t3003605
I got HiSuite installed and updated.
It is listed as "0123456789ABCDEF fastboot" ?

F:\Overførsler\ADB Flash Tools>fastboot flash boot BOOT_EMUI3.0_619_UNLOCKED.img
target reported max download size of 536870912 bytes
sending 'boot' (8038 KB)...
OKAY [ 0.309s]
writing 'boot'...
FAILED (remote: Command not allowed)
finished. total time: 0.309s

if you have emui 3.1 you can't flash a kernel for emui 3.0
a question: is your bootloader unlocked? (in fastmode under the green robot there is written in red letters phone unlocked)

EDIT: in your first post you write that the phone is locked...so you need an unlock code from huawei site in order to unlock bootloader, otherwise you will never be able to flash kernel or recovery

use this guide https://forum.xda-developers.com/ascend-p7/general/guide-root-huawei-p7-t3311424
and at point 8-9-10 use this https://forum.xda-developers.com/ascend-p7/orig-development/recovery-t3314665
