Xiaomi 13 (codename: fuxi) is a compact flagship with Leica-tuned cameras, Snapdragon 8 Gen 2 performance, IP68 resistance, and 67W wired charging—so firmware stability matters for camera speed, thermals, and daily smoothness.
Across user reports, common software complaints on Xiaomi 13 include camera lag/unresponsiveness (including slow gallery launch from the camera), aggressive RAM management that kills apps, and heat/battery concerns that become more noticeable after repeated “dirty” upgrades or advanced mods.
The official fastboot ROMs and the optional Xiaomi.eu package listed below are intended to restore a clean system base (correct region + correct partitions), address update-related glitches, and help recover devices that get stuck in fastboot/boot issues after ROM experiments.

⚠️ Flashing Risks & Disclaimer
- Flashing firmware on Xiaomi 13 (fuxi) is high risk because region builds (CNXM/MIXM/EUXM/RUXM/TWXM/TRXM) are not interchangeable, and mixing them can cause boot issues and missing network features.
- Bootloader unlocking is designed to trigger a factory data reset, and many clean-flash workflows erase data, so backups are mandatory.
- USB instability during flashing is dangerous; community support discussions explicitly warn that even slight USB disconnections can lead to severe failures/brick-like outcomes.
- Custom ROM activity can introduce additional risk; Xiaomi.eu users experiencing lag/heat often link it to long-term dirty flashing and heavy system modifications, which may require a true clean flash to recover smooth behavior.
- Proceed only after confirming codename = fuxi, selecting the correct region code, and fully understanding the erase/lock options in the flashing tool.

Flashing Requirements
- Windows PC/laptop, stable USB cable, and a reliable USB port (avoid hubs) to reduce disconnect risk while flashing.
- Unlocked bootloader for most fastboot flashing workflows; the Android unlock process is designed to factory reset the device.
- Correct region ROM choice (CNXM vs MIXM vs EUXM vs RUXM vs TWXM vs TRXM) to avoid mismatched firmware behavior.
- Fastboot access (Volume Down + Power) and recovery access (Volume Up + Power) for troubleshooting.
- Full backup completed (photos, authenticator codes, messages, app data), because clean installs are the most reliable fix for long-term dirty flashing slowdowns.
How to Flash the Firmware
Method A: Official Fastboot ROM (.tgz) via Mi Flash Tool
- Step 1: Download the correct region file (example: fuxi_eea_global_images_OS2.0.204.0.VMCEUXM…) and extract the.tgz to a simple folder path.
- Step 2: Boot Xiaomi 13 (fuxi) into Fastboot mode (Volume Down + Power).
- Step 3: Connect to PC, open Xiaomi Mi Flash Tool, and load the extracted ROM folder.
- Step 4: Select a clean-flash option when fixing lag/camera issues caused by long-term dirty flashing and updates.
- Step 5: Start flashing and do not disconnect the cable until completion to reduce brick risk.

Method B: Xiaomi.eu ROM (.zip) + TWRP/Fastboot (Advanced)
- Step 1: Confirm bootloader is unlocked; unlocking is designed to wipe data as part of the security model.
- Step 2: Download xiaomi.eu_FUXI_OS3.0.2.0.WMCCNXM_16.zip and keep it ready on PC storage.
- Step 3: Use Fastboot mode (Volume Down + Power) to boot/flash the recovery image if required for the chosen install route.
- Step 4: Perform the required wipes for a true clean install when troubleshooting camera lag and unstable multitasking behavior.
- Step 5: Reboot and verify boot; note that Xiaomi.eu community reports indicate some fuxi users experienced a fastboot-loop when moving from HyperOS 2.0 to 3.0, so having an official rollback ROM ready is recommended.
