The Xiaomi Mi 9 Pro 5G (codename crux), launched in late 2019, was a technological showcase and Xiaomi’s first 5G-enabled flagship for the public. It took the successful formula of the Mi 9 and elevated it with cutting-edge features, including the more powerful Qualcomm Snapdragon 855+ chipset and, most importantly, 5G connectivity. The device also shattered charging records with its blazing-fast 40W wired charging and a world-first 30W wireless charging capability. As this powerhouse was exclusive to the Chinese market, it never received an official Global ROM. This page provides the official China Fastboot ROM for device restoration and the essential Xiaomi.eu custom ROM, which adds Google services and multiple languages for international users.
Important: You must verify your device codename is crux. This firmware is not compatible with the standard Mi 9 (cepheus) or any other Mi 9 series variant. Flashing the wrong ROM will cause an irreversible hard brick.

How to Flash (China ROM)
For a step-by-step process, drivers, and troubleshooting, read our Ultimate Mi Flash Guide.

- Extract the China firmware (.tgz file) and select the main folder in Mi Flash Tool.
- Select clean all for a safe installation (avoid clean all and lock unless you want to return to a locked, stock China configuration).
FAQs
Q1. Is there an official Global ROM for the Mi 9 Pro 5G?
No. The Mi 9 Pro 5G was designed for the early 5G rollout in China and was never officially released in global markets. Therefore, no official Global ROM exists. The Xiaomi.eu ROM is the best alternative for users outside of China.
Q2. Can I flash a standard Mi 9 (cepheus) ROM on my Mi 9 Pro 5G?
Absolutely not. The Mi 9 Pro 5G (crux) has a different chipset (Snapdragon 855+), a 5G modem, and different charging hardware. Their firmware is completely incompatible. Cross-flashing will brick your device.
Q3. Why was the Mi 9 Pro 5G only sold in China?
The device was launched in 2019 when 5G network infrastructure was primarily being built out in China. Its integrated 5G modem was configured for Chinese cellular bands, making a wide international release impractical at the time.
Q4. The Xiaomi.eu ROM is a .zip file. How do I install it?
The .zip package is a recovery ROM and cannot be flashed with Mi Flash Tool. You must first unlock the bootloader, install a custom recovery (like TWRP), and then flash the .zip file from within the recovery interface.
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.
