Redmi Note 12 5G / Note 12R Pro (sunstone) HyperOS 2 Fastboot ROMs, Xiaomi.eu ROM & Custom Recoveries (Android 14)
Redmi Note 12 5G (codename sunstone) is a popular 5G mid-range phone built around a 6.67-inch 120Hz AMOLED display, Snapdragon 4 Gen 1, and a 5000mAh battery with 33W fast charging. If you are here, it usually means you need a clean, reliable way to fix software trouble such as laggy performance on HyperOS/MIUI builds, or a device that won’t boot correctly after flashing experiments.
The firmware files below are designed to help you restore a stable stock system (official Fastboot ROMs), or move to a custom Xiaomi.eu build with custom recovery (TWRP/OrangeFox), depending on what you are trying to fix.
File Selection Guide.
Pick the right file based on your exact region build and whether you want stock Xiaomi firmware or a custom ROM.
- Confirm the device codename: These files are only for Redmi Note 12 5G / Redmi Note 12R Pro with codename sunstone.
- Stock vs custom: The
.tgzpackages are official Fastboot ROMs (best for unbricking, fixing broken updates, or doing a clean reinstall), while the Xiaomi.eu.zipis a custom ROM that typically needs a custom recovery. - Region matters (do not mix): Your build suffix should match your region:
- CNXM = China
- MIXM = Global
- INXM = India
- EUXM = EEA (Europe)
- TWXM = Taiwan
Firmware trackers list separate releases per region, so cross-flashing the wrong region is risky and should be avoided.
- If your phone feels slow/laggy: Users have reported very laggy behavior on Redmi Note 12 5G running HyperOS builds, so a clean flash of the correct stock Fastboot ROM is often the safest troubleshooting step (especially when the device has been modified).
- If you are using Xiaomi.eu: A Xiaomi.eu community report shows some users experienced the phone booting back into Fastboot after flashing a Xiaomi.eu HyperOS 2 build, and the team later marked the issue as resolved (dependency conflict) with ROM reuploads planned.

- Load ROM: Open Mi Flash Tool and select the extracted ROM folder.

Can I flash the China (CNXM) ROM on my Global (MIXM) Redmi Note 12 5G?
