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 Japan phone on an older version. This is a Pilot build: phones outside the pilot group often refuse it with “Installation of this software version is prohibited”, so you may have to wait for the stable release. 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 Redmi Note 17 Pro Max 5G firmware page. Installing an older version? Read how to check anti-rollback first; switching region? See ROM region codes.
