Root Problems with unlocking bootloader (ADB)

[vage013]

So, i wanted to update my device since its running the vanilla rom. Updating with the newest rom from the Huawei site failed (supposedly because my device isnt rooted yet).
I went on a quest to unlock the bootloader and root the phone (and updating the device when this is done)

I found a nice guide where they gave me a few programs that i did download.
(https://www.dc-unlocker.com/free-huawei-bootloader-unlock-tutorial)

Android SDK (Didnt use it so far)
DC-Unlocker (gave me the code so this worked)
ADB.

Now im stuck at the ADB part. I connect my phone to the PC (without fastboot mode) > ADB Devices will show my phone, but when i try to execute the command fastboot devices it will not show up. It wont show up when the phone is in fastboot nor in normal mode, not with USB debugging on or off.
The driver is properly installed it says in the device manager (Android Phone > Android Composite ADB Interface)

Also it gave an error that WinAPI.DLL wasnt installed or something to i copied those from the ADB directory to the bin\files directory (and now at least it wont give that error anymore)

I run Windows 7 x32.

You need to have your device in fastboot, which can be tricky depending on the device. Usually you turn the phone off all the way..taking the battery out for about 5 seconds will make sure. Then press the power button at the same time you press the volume down button. Hold for about ten seconds. There is a way to test to make sure your device is connected via fastboot. run "fastboot devices" from the adb command line. you should get back something like "847495876 fastboot". Then you know your ready to run "fastboot oem unlock (insert the code here)"

you can also do "adb reboot fastboot" from normal mode, but this doesnt always work.

adb reboot fastboot
Doesn't work, but

adb reboot bootloader

This will boot into fastboot mode same as holding vol down and power buttons
But that command don't seem to work after custom recovery is on.
I recommend TWRP 2.7.0.2
Get it from openrecovery
