You must enable "OEM Unlocking" in Developer Options before booting to fastboot. If it's grayed out, connect to the internet and wait 72 hours (a Google/Android requirement).
If your Sunmi V2 is running an older version of Sunmi OS, check if the developer options can be forced open via a specific calculator app shortcut or an older configuration exploit. If accessible, you can toggle USB Debugging directly, use standard ADB commands to boot into fastboot, and flash older developer-signed firmware variants that have root access pre-compiled by the community.
