Flashing Requirements
- Verify codename: In fastboot mode, run fastboot getvar product and ensure the result is chenfeng before using any of these ROMs.
- Match the region and OS level: Use OS2.0.207.0.VNJCNXM only for Chinese Civi 4 Pro, OS2.0.208.0.VNJINXM for India 14 Civi, and OS1.0.10.0.UNJINXM only if you intentionally stay on or revert to Android 14 India firmware.
- Bootloader status: Unlock the bootloader for fastboot ROMs (.tgz); the OS1.0.10.0 recovery ZIP can be installed via stock recovery on a locked‑bootloader India device.
- PC, drivers and tools: For fastboot ROMs, prepare a Windows PC with Xiaomi USB drivers, Xiaomi Mi Flash Tool and a reliable USB‑C cable plus at least 15 GB free space.
- Backup and battery: Charge the phone to at least 60% and back up internal data, as “clean all” fastboot flashes or full wipes during recovery installs will erase apps, media and settings.
How to Flash the Firmware
HyperOS 2 fastboot images for chenfeng are meant for full PC‑based flashes, while the HyperOS 1 recovery ZIP can be installed directly on the phone via stock recovery or local update, giving flexibility depending on whether you want a deep clean or a simple in‑place refresh.
Fastboot ROMs (.tgz) – HyperOS 2.0.207.0 / 2.0.208.0
- Download and extract: Download the correct chenfeng_…_images_OS2.0.207.0/208.0… file and extract it until you see the images folder and flash_all*.bat scripts.
- Configure Mi Flash: Install Xiaomi USB drivers, open the Xiaomi Mi Flash Tool and select the extracted ROM folder.
- Enter fastboot: Power off the phone, hold Volume Down + Power to enter fastboot mode, connect to the PC and click “Refresh” in Mi Flash to verify detection.
- Flash with clean all: Choose the clean all option, click “Flash” and wait until Mi Flash shows success without unplugging the cable or powering off.
- First boot: Reboot into HyperOS 2; the first start can be slow while apps are re‑optimized, after which you can check battery life, smoothness and camera performance.
Recovery ROM (.zip) – HyperOS 1.0.10.0.UNJINXM
- Copy the ZIP: Download miui_CHENFENGINGlobal_OS1.0.10.0.UNJINXM… and place it in the phone’s internal storage.
- Open updater / recovery: Either use the built‑in “System update” app’s local update option or boot to stock recovery.
- Select the package: Point the updater to the OS1.0.10.0 ZIP and confirm installation, ensuring the battery is sufficiently charged.
- Wait for flashing: The phone will verify and install the package, then reboot automatically once done.
- Factory reset if needed: If you see glitches after a major downgrade, perform a manual factory reset from recovery after backing up your data.

Frequently Asked Questions (FAQs)
What is the difference between OS2.0.207.0 / OS2.0.208.0 and OS1.0.10.0 on chenfeng?
OS2.0.207.0 (China) and OS2.0.208.0 (India) are HyperOS 2 Android 15 releases with newer security patches and system‑stability optimizations, giving you the latest feature and security baseline. OS1.0.10.0.UNJINXM is an older HyperOS 1 Android 14 build for India that focuses on fixing rare non‑responsive behaviour and improving general stability, useful if you prefer a more mature base.
Will updating to HyperOS 2.0.208.0 fix battery drain on my Xiaomi 14 Civi?
The OS2.0.208.0 India changelog emphasises stability and updated security patches rather than explicit battery changes, but Xiaomi has been actively tuning HyperOS 2 to reduce battery drain across devices. Many guides recommend combining a clean flash or factory reset with power‑saving settings to see the biggest improvement in standby and screen‑on time.
Can I safely downgrade from HyperOS 2 to OS1.0.10.0 Android 14?
Technically, you can move from HyperOS 2 to OS1.0.10.0.UNJINXM using the India recovery ZIP, but you must wipe data and accept the risks of downgrading system components. Always back up data first and be prepared to factory reset if you encounter app crashes or incompatibilities after the downgrade.
Do I need to unlock the bootloader to install these ROMs?
The chenfeng fastboot packages (OS2.0.207.0.VNJCNXM and OS2.0.208.0.VNJINXM) require an unlocked bootloader to flash through Mi Flash or fastboot scripts. The OS1.0.10.0.UNJINXM India recovery ZIP is designed for stock recovery and can be installed on a locked‑bootloader Xiaomi 14 Civi.
How can I confirm that my device is really the chenfeng variant?
Check the codename in fastboot with fastboot getvar product; Xiaomi Civi 4 Pro / Xiaomi 14 Civi units targeted here report chenfeng. You can also verify your model number (such as 24053PY09I for India) against firmware lists to ensure you are downloading the correct region’s ROM.
