Download Xiaomi MIX Fold 3 HyperOS 2 Fastboot ROM (OS2.0.209.0.VMVCNXM)
If you’re using the Xiaomi MIX Fold 3 (codename: babylon, China region), this official HyperOS 2 fastboot firmware package (OS2.0.209.0.VMVCNXM) is designed to restore/refresh your system, especially when you’re dealing with unstable performance, update errors, or a software-corruption scenario that an OTA update can’t fix.
File Selection Guide
This firmware is for the China MIX Fold 3 variant and matches the HyperOS build suffix CNXM (shown inside OS2.0.209.0.VMVCNXM).
- Best match check (recommended): Your current version/build in “About phone” should also end with
CNXMif you’re on the same regional branch. - Device match check: The package name is explicitly listed as a MIX Fold 3 China update for codename
babylon, so it should not be used for other Xiaomi foldables or global/EEA variants. - Choose the right flashing type: The file you provided is a
.tgz“Fastboot” ROM, which is meant for PC-based flashing (not the in-phone updater).
If the phone is bootlooping or the system is badly corrupted, a fastboot ROM is often the more reliable choice because it rewrites multiple partitions in a controlled PC flashing flow (compared to a standard updater flow).

Flashing Requirements
Flashing a fastboot ROM can wipe user data depending on the flashing option used, so a full backup should be completed first.
- A Windows PC (typical for Mi Flash Tool workflows).
- A good USB cable and stable USB port (avoid loose hubs).
- Enough battery charge (50%+ recommended) to reduce interruption risk.
- Extracting tools for
.tgz(because fastboot ROMs ship as archives).
Fastboot flashing for Xiaomi devices is commonly done using Mi Flash Tool for official fastboot packages.

What this firmware actually fixes
The publicly posted changelog for OS2.0.209.0.VMVCNXM specifically says it updates the Android security patch to November 2025 and increases system security.
No additional fixes (battery/camera/network/UI) are listed on the public changelog entries available for this build, so it would be inaccurate to promise specific bug fixes beyond security hardening.
That said, many MIX Fold 3 troubleshooting write-ups frequently mention heat/battery-drain style complaints during heavy use, and users often try system updates as part of their troubleshooting checklist—just note that this is general guidance from third-party troubleshooting sources, not an official promise for this exact build.
