The Xiaomi Mi 9 Lite / Mi CC9 (codename pyxis), launched in 2019, was a masterclass in delivering a premium experience at a mid-range price. It captured attention with its stunning 6.39-inch Super AMOLED display, complete with an in-screen fingerprint scanner, and its stylish, iridescent glass back. The device was a strong performer, powered by the efficient Qualcomm Snapdragon 710 chipset and a large 4030 mAh battery. It also excelled in photography with a versatile 48MP triple rear camera and a high-resolution 32MP selfie camera. For owners looking to restore, unbrick, or perform a clean installation, this page provides a comprehensive list of official fastboot ROMs for China, Global, Russia, and EEA, along with the popular Xiaomi.eu custom ROM.
Important: You must verify your device codename is pyxis. The Mi 9 Lite / Mi CC9 is a distinct model within the Mi 9 series. Flashing firmware from a Mi 9 (cepheus), Mi 9 SE (grus), or Mi 9T (davinci) will hard brick your device.

How to Flash
For a step-by-step process, drivers, and troubleshooting, read our Ultimate Mi Flash Guide.
- Boot into Fastboot mode (Power + Volume Down).

/imagesdirectory in Mi Flash Tool. - Select clean all for a safe installation (avoid clean all and lock unless you are on the correct stock ROM for your specific region).
FAQs
Q1. What is the difference between the Mi 9 Lite and the Mi CC9?
They are the same phone in terms of hardware. “Mi CC9” was the name for the original release in Mainland China, while “Mi 9 Lite” was the name used for the global and European markets. They both share the pyxis codename.
Q2. Can I flash a Mi 9 (cepheus) or Mi 9T (davinci) ROM on my Mi 9 Lite?
No, absolutely not. The Mi 9 series consists of several distinct models with different processors and hardware. Flashing firmware from another model will cause a hard brick. Always ensure the firmware is for the codename pyxis.
Q3. What was the final official update for the Mi 9 Lite?
The Mi 9 Lite launched with Android 9 (Pie) and received its final major OS update to Android 11. Its last significant MIUI version was MIUI 12.5.
Q4. The Xiaomi.eu ROM is a .zip file. How do I install it?
The .zip file is a recovery ROM, which requires a custom recovery like TWRP to be installed. It cannot be flashed using Mi Flash Tool, which is designed for .tgz fastboot packages. You must unlock your bootloader first.
Troubleshooting
- Drivers: If your PC does not recognize the phone in fastboot mode, reinstall the Xiaomi USB drivers, run Mi Flash Tool as Administrator, or try a different USB port (USB 2.0 is often more stable).
- Fastboot errors:
- “error: not catch checkpoint” → This common error means you have selected the wrong folder. In Mi Flash Tool, be sure to select the parent folder that was created when you extracted the .tgz file, not the images folder inside it.
- “Anti rollback error” → You are attempting to flash an older firmware version than what is currently on the device. Xiaomi’s Anti-Rollback Protection (ARB) prevents this.
- EDL mode: For a hard-bricked phone that won’t enter fastboot, EDL mode is the last resort. It requires using hardware test points and is recommended for advanced users only.
