How to Install This Update
Download the Recovery ROM, move it to the internal storage and choose Settings → About phone → (tap the OS card) → three dots → Choose update package. This keeps your data, but only works for a Russia phone on an older version. For a clean install or a region change, flash the Fastboot ROM with Mi Flash (unlocked bootloader required).
