Before we start, I'd like to say that what you are about to do isn't illegal or strictly against the League terms of use. In the ToS (
termsofuse - The full guide to getting and using the Korean LoL client on your home region

https://euw.leagueoflegends.com/en/legal/termsofuse ), specifically section 5 "Code of Conduct", heading 5.1, paragraph IX, it says:
  1. Using any unauthorized third party programs, including mods, hacks, cheats, scripts, bots, trainers and automation programs that interact with the Software in any way, for any purpose, including any unauthorized third party programs that intercept, emulate, or redirect any communication between the Software and Riot Games and any unauthorized third party programs that collect information about the Game by reading areas of memory used by the Software to store information;

However, we are not using any third party program to modify the game files, and as you will soon find out, it's a very simple file swap that is already located in the league of legends folder when you download the game.

First, I'd like to outline the usages of using the korean client instead of your home region's:

  • For some reason, the korean client is way less buggy than the non-KR ones which means that you can use the client with it's normal settings or without the use of the "Low Spec Mode" if you enjoy visual clarity at the cost of no decreased or fundamental change in performance (apart from running the process, it doesn't clog itself up)
  • The ability to listen to the korean voice packs for all champions, maps, effects and noises in the game.
  • To read and/or learn the Korean language
  • To use the "korean" text font that is different from the base non-KR one.

How it works: We are able to use the KR client whilst still connecting to our home servers by modifying a game file called system.yaml that is located in the RADS directory of the game. The reason why we need to modify it is because we cannot simply change the locale_language to korean because in Korea, to play on a LoL account you must use your SSN, and since most people using this trick are not members of the Republic of Korea, you do not have an SSN to register it. We bypass this by generating the authentication token from your home server and putting it in the korean client directory. Effectively, we are using the KR client, with KR text, voice and font, but are actually logging into onto our home server.

Tools Required: An IDE/Text Editor (Notepad is the most basic, I recommend Sublime Text for clarity: https://www.sublimetext.com/3 )


Step 1) Close down your client.

Step 2) Download the KR client installer here: http://www.leagueoflegends.co.kr/?m=download

Step 2b) If you only have 1 hard drive (C:) and have League on it, make a separate folder called "League of Legends KR" and assign it for your KR client to be downloaded there.

Step 3) Run the installer and finish the installation. The game should automatically launch when you finish the installation.

Step 4) Let the game patch. If you are from EU or NA and have a good download speed, your download will be capped at 1mb/s download speed because you are downloading from KR.

Step 5) Once your game is fully patched, close down your KR Client.

Step 6) Find your League of Legends directory. For me this is on C:Riot Games.

Step 7) Access the system.yaml file in your home region's folder. For me, this path looks like this:
