You will need:

-$20/$22/$55 depending on your preferences.

-A Windows PC. (PM me if you have a Linux one, I will update the guide accordingly)

-A working SD card that is tested and working with your phone.

-A reliable USB cable which works for connecting your phone to your PC.

-A backup (optional)

PART 1: Bootloader Unlock

To unlock your bootloader you need a bootloader unlock code. Huawei stopped giving bootloader codes in end of July. But you can buy one in one of the webistes below. You have to send your IMEI to them, and they will generate the unlock code and send it to you. You can see your IMEI at System>>About Phone>>IMEI.

1.) Global Unlocking Solutions for $20/$22

First of all, I know that the website looks super sketchy. But [MENTION=8567424]medoamer[/MENTION], myself, and a lot of other XDA users had success with this method. I spent the extra $2 for the fast service, but it is up to you.

2.) FunkyHuawei for $55

The advantage of FunkyHuawei is that they have a good track record with XDA and other services, a refund policy, and just you know what you are getting into. You can ask for a refund if the code does not work.

3.) Ministry of Solutions for €30

A lot of XDA users had success with this method also. I don't know much information about this method, but the ysay they offer a refund if the code doesn't work.

Got the code? Good. You are mostly done now...

Install ADB and Fastboot. I'm not going to give a guide on how, you can search for it. Download and install Hisuite from here. Connect your phone to your PC, and open a command prompt on your ADB folder. Run,

adb reboot bootloader

Wait for your device to reboot and show a screen with title "FASTBOOT & RESCUE MODE". In the next command replace <code> with the unlock code you bought. The next step will wipe all the data on your device, so you might want to backup your important data.

fsatboot oem unlock <code>

Congratulations, you just unlocked the bootloader of your device. Your warranty is legally void now. Reboot the device with the command;

fastboot reboot

PART 2: Install TWRP and Magisk

First, connect your SD card to your phone, download Magisk ZIP here, and place it in your SD card.

Reboot to Fastboot again with,

adb reboot bootloader

Download the TWRP image here and copy it your ADB folder. Use this command to flash TWRP.

fastboot flash recovery_ramdisk twrp-kirin.img

Hold the power button to turn your phone off. Disconnect your phone from your PC. Now hold the power button and Vol. Up button until the Huawei logo appears, then let go of both buttons. The blue TWRP logo should appear and after a second you would see the TWRP menu. If you see the Keep System Read-Only menu, swipe right.

Go to Install>>Select Storage>>Micro SD Card. You should see the Magisk ZIP you placed there earlier. Select it, and Confirm to flash. After the flashing is over, reboot your phone.

Congratulations, now you have a rooted device!

If you need any help along the way, or end up bricking your device, I will help you the best I can.

Good Luck!
