Lobby Crasher for League of Legends (DOESN'T WORK SINCE 14.4)

Lobby Crasher for League of Legends

Dodge your ranked games without any penalty

But why you leaked it?

It doesn't work since 14.4 patch, and then I decided to make this project public. Code has some inconsistencies and I don't want to improve it since Riot fixed this exploit. Use this project for study purposes only

How DID it work?

1. Quit your current gameflow
2. Get these values through LCU requests:

• Game version
• RSO Inventory JWT
• RSO Id token
• RSO Access token
• League Session token

3. Generate custom lobby based on your gotten values
4. Send custom lobby to the client
5. Start champion selection stage in this custom lobby
6. Wait some time (12-15 seconds is enough I guess)
7. Again, quit your current gameflow
8. Send setClientReceivedGameMessage LCDS request to gameService destination
