Contact Riot Support: If you believe your ban was a mistake, submit a support ticket. They can review your case and, if an error occurred, lift the ban legitimately.Hardware Upgrades: While expensive, replacing the components flagged by Riot (usually the motherboard and SSD) is a physical way to change your HWID, though Vanguard’s tracking is becoming increasingly complex.Clean Start: After your ban period expires, ensure you have removed all prohibited software from your system before attempting to play again to avoid a secondary ban.
