How to Install This Update
Download the Recovery ROM, move it to the internal storage and choose Settings → About phone → tap the OS card → tap the HyperOS logo 7–10 times → three dots → Choose update package. This keeps your data, but only works for a Global phone on an older version. For a clean install or a region change, flash the Fastboot ROM with Mi Flash (unlocked bootloader required). Step-by-step instructions are on the Mi 11i firmware page. Installing an older version? Read how to check anti-rollback first; switching region? See ROM region codes.
