I DO!!!
No scam frlfrl. Read this carefully. Any cv1 device including this one is eligible to root. It's an LG X210 also known as cv1. So it's firmware is the same but it's a different carrier. The LG Aristo 2, LG Aristo 2+, LG K8+, and the LG Pheonix 4 are all cv1. Previously it was thought that only LG Aristo 2, 2+ and K8+ were the only cv1 devices, but now thanks to AustinGarrick1818, we have now relized that our cv1 TWRP can be used for the LG Pheonix 4 and of cource your LG K9!
I will post a root method soon for all of the cv1 devices.

Well since I don't have the device I'm going to need testers to tell me if it works or not.
Method 1:
1. Developer Options
The bootloader should be locked, but you can OEM unlock it in developer settings. Most everyone should know how but just in case goto Settings -> About and find Build Number. Click it 5-6 times and Developer Options should show up in settings.
Goto Developer Option and enable OEM Unlock and usb debugging.
2. ADB Drivers
If you already have adb drivers on your computer just restart your device and plug it into your PC. Open a command prompt in you adb folder and type in "adb devices". If you don't you will need to install ADB Drivers from another forum and do the same as everyone else. You will need to give authorization to USB Debugging once you type in adb devices. If it shows unauthorized then type in adb reboot fastboot. This should prompt that debugging authorization on screen. Click Allow and you device should reboot to fastboot mode. If this doesn't work goto Method B(Bottom of Post)
3. Fastboot
Fastboot should and most likely will come with the ADB Drivers. Instead of using adb we use fastboot commands. So type in fastboot devices to check that your device is connected. If it shows that it is connected then you can move on to the next step.
4. OEM Unlock
From the command prompt type "fastboot oem unlock" or "fastboot flash unlock". This will erase you data but once it's done you will need to do it again because the userdata partition and cache will be encrypted. Type "fastboot erase userdata" and "fastboot erase cache". Move on to step 5 if it works. If this doesn't then go to Method B.
5. Installing TWRP
Download this and install it by typing "fastboot flash recovery TWRP-3.2.3.0-cv1.img". If it works type "fastboot reboot recovery".
Method 2
Note: This is what might have to happen for TWRP to be installed
1. Basic Information
The fastboot partition might be encrypted, adb might not reboot to fastboot, and or fastboot isn't install TWRP.
2. Fix(ANOTHER NOTE: I'M NOT RESPONSIBLE FOR BRICKS)
Power off your phone. Boot into download mode by holding the Volume UP and plugging the device into your PC. You'll need LG UP, to install the Aristo Firmware. Theoretically the cv1 devices are the exact same build as one another just under different carrier names
and build numbers. So flashing the LMX210MAK10 firmware should fix it. Download it and flash it then go back to method 1 to try again.
If you have any questions or comment quote my method and let me know further issues.

But there are some problems: The LMX210BMW is the only build that supports dual SIM.

Editing above: nevermind the above post. According to LG website, the only builds of LMX210 that support dual SIM are: BMW, EMW, IMW, NMW, and YMW. The BMW we know that the bootloader is hardlocked. So, we need to test which other LMX210 builds aren't hardlocked.

Comigo não rolou, definativamente desisti.Ainda teve varias pessoas relatando que não inicializa no bootloader.Acho que o problemas ta nesse modelo com dois chips. Nunca consegui iniciazar no bootloader, simplesmente reinicia voltando pro sistema.Quase perdi o aparelho fazendo o flash da imagem que foi postada, tive que instalar imagem stock pra poder voltar a usar o aparelho.

Também desencanei

Pois é, eu tb desencanei de perder tempo tentando acessar o bootloader.
Para mim era algo relacionado a um bloqueio colocado pela operadora que vendeu o aparelho (no meu caso, Vivo), mas não tenho conhecimento técnico para afirmar se é isso ou o lance dos dois chips...
Se alguém tiver sucesso no processo ou dicas, manda aqui!

Valeu pelo link, Rodrigo.
Porém os arquivos TWRP linkados na postagem dentro desta postagem estão indisponíveis.
Você conseguiu baixá-los?
São estes aqui:
unsigned_twrp_lg-k9_temp.zip
signed_twrp_lg-k9.zip
Estou googlando atrás deles, até agora sem sucesso.
Caso consiga, posto aqui.
Obrigado!

i've tested the YMW, and it's hardlocked too.
