Xiaomi Mi 9 SE (grus) Firmware Flash File Download [Stock Rom]

The Xiaomi Mi 9 SE (codename grus), launched in 2019, was a rare and celebrated device for users who craved flagship features in a compact, one-hand-friendly package. As the “Special Edition” of the Mi 9 series, it offered a premium experience without the large footprint. The device was the first to be powered by the powerful upper mid-range Qualcomm Snapdragon 712 chipset and featured a stunning 5.97-inch Super AMOLED display, an in-screen fingerprint scanner, and a versatile 48MP triple camera setup. For enthusiasts of this “pocket rocket,” this page provides the official fastboot ROMs for China and Global, along with the popular Xiaomi.eu custom ROM, to help restore or repair your phone’s software.

Important: You must verify your device codename is grus. The Mi 9 SE is a unique model. Its firmware is not compatible with the flagship Mi 9 (cepheus) or the Mi 9 Lite (pyxis). Flashing the wrong ROM will cause a hard brick.

How to Flash

For a step-by-step process, drivers, and troubleshooting, read our Ultimate Mi Flash Guide.

1. Boot into Fastboot mode (Power + Volume Down).
2. Extract the firmware (.tgz file) and select the main folder containing the /images directory in Mi Flash Tool.
3. 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. Can I flash a Mi 9 (cepheus) or Mi 9 Lite (pyxis) ROM on my Mi 9 SE?
No, absolutely not. Despite being in the same series, these three phones have different chipsets (Snapdragon 855, 712, 710 respectively), screen sizes, and hardware. Their firmwares are not interchangeable, and cross-flashing will brick your device.

Q2. What was the final official update for the Mi 9 SE?
The Mi 9 SE launched with Android 9 Pie and received two major OS upgrades, with its final official version being Android 11. The MIUI 12.5 builds provided here are the last software updates released for the device.

Q3. What was the main appeal of the Mi 9 SE?
Its primary selling point was its compact size without significant compromises. It offered a premium Super AMOLED display, a powerful Snapdragon 7-series processor, and an in-display fingerprint scanner in a form factor that was comfortable for one-handed use—a true rarity.

Q4. The Xiaomi.eu ROM is a .zip file. How do I install it?
The .zip file is a recovery-flashable ROM. You cannot use Mi Flash Tool. You must first unlock your 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.
