[Android Q&A, Help & Troubleshooting] Sathelp:
I still do not have root as I need a valid EMUI 3.0 CWM or TWRP recovery but I do have an extracted EMUI stock recovery that I have been using while testing various supposedly Honor 6 Plus Recoveries!

So here is the Bootloader unlocking instructions taken and modified from here

Introduction

Bootloader unlocking works by using the fastboot command line utility and executing a specific command containing a ‘bootloader unlock code,’ which is unique to each specific device and must be generated based on the IMEI and serial number of the device. Once the bootloader is ‘unlocked,’ this gives us permission to flash (or overwrite) sections of the phone memory with code of our own choosing – allowing us to install recoveries, gain root access, and utilise custom ROMs (once they are available).

Huawei provide a website to generate bootloader unlock codes , but this unfortunately does not list the entirety of the Honor 6 Plus, so we have to get creative. Fortunately, there are resources available us to generate a ‘fake’ product ID for an existing model number which can trick the unlock code generator into providing us a valid code for our Honor 6 Plus, and therefore allow us to execute the bootloader unlock successfully.

Generating a Product ID

If you visit the bootloader unlock generator page (this is a page setup by Huawei themselves), you can see there are a number of required fields; namely product model, product serial number, product IMEI and product ID.

However, after selecting smartphone, you will notice that there are no Honor 6 Plus devices present in the model list – and therefore we need to generate our own product ID. To do this, download the Huawei_Product_ID_Generator (Windows only, I’m afraid) file and extract it to your machine. Please note that we did not develop this application and have no knowledge of any malware it may contain – please use your best judgement and always use antivirus when installing unknown software.

Once you have extracted the application, execute it by double clicking the .exe file. When the window appears, select Y300-0000 from the model list, and enter your devices IMEI in the field below the selection box. You can find your device IMEI on the box your Honor 6 Plus came in, or alternatively navigate on the device to Settings > About Phone > Status and your IMEI will be listed.

Selecting Y3000-000

After selecting Y300-0000 and entering your IMEI code, your newly generated product code will be visible in the lower box. Save this number or write it down somewhere safe, and move on to the next step, getting hold of the bootloader unlock code itself.

Getting a Bootloader Unlock Code

At this point, we need to go back to the official Huawei bootloader unlock code generator page. Now that we have a product ID, we are able to generate an unlock code quite easily. First of all, select Smartphone for device type, then select Y300-0000 (about halfway down) for the product model. The remaining fields should be fairly straightforward – fill in your IMEI and serial number (either from the box or on your phone in Settings > About Phone > Status) into the appropriate boxes.

For the product ID, enter the one you generated with the generator earlier – not the one of your actual device. Once all fields have been filled, complete the CAPTCHA at the bottom of the field and click ‘submit.’

If everything has been completed successfully, you will now be in possession of your unlock code. Congratulations!

Driver Installation

Now that you have an unlock code, we can move forward with unlocking the bootloader. First of all, you’ll need to download the package containing required drivers and utilities for the phone, extract it to your computer, and navigate to the resultant directory.

You will likely need to install drivers for your device, so do this now – extract the Drivers file and navigation within, then execute DriverSetup.exe and allow it to complete. When this installation has completed, restart your computer as advised by the driver installation wizard. The requisite software for the bootloader unlock and recovery installation should now be prepared and active on your computer.

Bootloader Unlock

You will need to get and down and dirty with a bit of command line magic in order to actually unlock your bootloader. The simplest way to open a command prompt in the correct place is to navigate into the adb_tools folder or somewhere you have them, and open a command line window and cd ****** to this folder. Your should have fastboot etc in this folder if correct.

The first thing to check is whether or not our device has been detected. Within the command prompt in the tools directory, enter the following command and then hit enter:

adb devices

If you don’t see any output after this, you probably need to install drivers. Install the included driver package, restart your machine, then try again. On the other hand, if you see a device listed, then everything has been detected correctly and you will be able to unlock your bootloader straight away. You then need to put your Mate 7 device into bootloader mode. The easiest way to do this is to enter the following command into the command prompt and hit enter:

adb reboot bootloader

This will get you into the bootloader mode of your device. You may have to press ‘okay’ on a phone screen popup to allow the adb command to connect properly. Once in the bootloader, we can perform the bootloader unlock. To do this, simply enter the following command and hit the enter key – replacing YOURUNLOCKCODE with the code we generated earlier:

fastboot oem unlock YOURUNLOCKCODE

If everything works correctly, you will be given a message in the command prompt, and the phone bootloader screen will now stated ‘PHONE Unlocked.’ Congratulations! You now have an unlocked bootloader.
