Because WOHCNXM is a China‑only build, users coming from global or custom ROMs should only flash it if they understand the implications for language packs, Google services and future OTA updates.
Flashing Requirements
- Windows PC with Xiaomi USB drivers and Mi Flash Tool installed, plus at least 20 GB of free disk space for the extracted fastboot package.
- Unlocked bootloader on the MIX Flip 2, obtained through the official Xiaomi unlock procedure before using fastboot ROMs.
- Good quality USB‑C cable and stable USB port to avoid disconnections during the flash process.
- Battery charged to a minimum of 50–60 % to reduce the risk of shutdown mid‑flash, which can hard‑brick the device.
- Full backup of photos, messages and app data, since most fastboot flashing modes will wipe user data and internal storage for best stability.
How to Flash the Firmware
Quick steps – Mi Flash Tool with bixi fastboot ROM
- Download the bixi_images_OS3.0.3.0.WOHCNXM… .tgz file and extract it twice until you see the images folder and the flash_*.bat scripts.
- Launch Mi Flash Tool, click “Select” and point it to the extracted firmware directory that contains the configuration and images.
- Boot MIX Flip 2 into fastboot mode, connect it to the PC and press “Refresh” in Mi Flash to confirm the device is detected.
- Choose your flashing mode (for example “clean all” for a full wipe) and click “Flash”, then wait patiently until Mi Flash reports a successful result.
- Reboot the phone; first boot into Android 16 / HyperOS 3 can take several minutes while apps and services are re‑optimized.
Quick steps – fastboot script (flash_all.bat)
- Install Google’s platform‑tools (fastboot) on your PC and open a command window in the folder where you extracted the bixi fastboot ROM.
- Enter fastboot mode on the MIX Flip 2, connect it and verify recognition with fastboot devices.
- Run the script that matches your needs, such as flash_all.bat to wipe and flash all partitions, or flash_all_except_storage.bat if included and you want to keep internal storage.
- Let the script complete; do not disconnect the cable or close the window until all commands finish without errors.
- Reboot and complete setup; after a major Android jump, consider an extra factory reset if you still notice abnormal lag or drain.

Frequently Asked Questions (FAQs)
What problems can HyperOS 3.0.3.0 fix on MIX Flip 2?
A full fastboot flash can recover MIX Flip 2 units stuck in bootloops, suffering from repeated app crashes, broken OTA updates or instability after experimenting with root or custom mods. It also gives you a clean install of Android 16 / HyperOS 3, which includes Xiaomi’s latest bug fixes and performance optimizations for HyperOS devices.
Will this ROM improve battery life and performance?
HyperOS updates often tweak background process management, thermal policies and kernel components, which can help with lag and abnormal battery drain seen on some earlier builds. However, some users across HyperOS devices still report higher drain or sluggishness after updating, so a clean flash and careful app configuration are recommended for best results.
Is bixi_images_OS3.0.3.0.WOHCNXM multi‑language and does it include Google apps?
As a China (CN) build, WOHCNXM focuses on Chinese and English languages and does not normally ship with the full Google app suite pre‑installed. Google services can usually be added afterwards, but behaviour may differ from official global ROMs, and OTA updates will continue to follow the China channel only.
Do I need to unlock the bootloader to flash this ROM?
Yes, manual fastboot flashing of HyperOS ROMs via Mi Flash or scripts requires an unlocked bootloader on Xiaomi devices, including MIX Flip 2. Locked‑bootloader users should stick to official recovery/OTA updates pushed directly to the phone instead of fastboot packages.
What if my phone is still unstable after flashing OS3.0.3.0?
If you performed a clean flash and the phone still overheats, drains battery quickly or lags heavily, the cause may be third‑party apps, leftover settings or even hardware issues rather than the ROM itself. Try another factory reset, review installed apps and, if problems persist, consider contacting Xiaomi service or waiting for the next HyperOS maintenance release.
