Q1. What phone is “babylon” and is this ROM for it?

babylon is the codename for Xiaomi MIX Fold 3 (commonly listed with model 2308CPXD0C), and this package is labeled for babylon with the CN branch (CNXM).

Q2. What does OS2.0.209.0.VMVCNXM change compared to older builds?

The published changelog highlights an updated security patch level to November 2025, which typically targets system security hardening and stability foundations rather than flashy UI additions.

Q3. Can flashing this help if my MIX Fold 3 started having SMS issues after HyperOS?

Some MIX Fold 3 owners report SMS send/receive problems after a HyperOS update, and a clean flash of the latest matching region firmware is a common “reset-to-stock” fix attempt when OTA upgrades leave modem/app conflicts behind.

Q4. Will this ROM reduce overheating and battery drain after updating?

Battery drain and heat spikes are frequently reported after HyperOS updates across Xiaomi devices, and moving to a newer build plus doing a clean flash can help by removing background/app migration conflicts—though results vary by apps and usage.

Q5. Is this firmware safe to flash on a Global/EEA MIX Fold 3?

This file is explicitly a China (CNXM) build for babylon; cross-region flashing is higher risk and can create network/OTA inconsistencies, so the safest choice is always the build that matches your device’s original region.

Q6. Why does HyperOS sometimes feel slower after an Android 15 upgrade?

Community reports describe stuttering/lag (sometimes camera-related) after HyperOS/Android 15 updates on some models, and a clean flash is often used to rule out “dirty upgrade” leftovers as the cause.

Q7. What’s the #1 mistake people make with MIX Fold 3 fastboot ROMs?

Flashing a ROM meant for the wrong codename/variant (or skipping file integrity checks) is the fastest path to bootloops and failed flashes, so always confirm babylon and validate the MD5 before proceeding.

Preparation Before Flashing

Click here for the Xiaomi MIX Fold 3 (babylon) pre-flash checklist

Confirm codename + model: Verify your device is MIX Fold 3 (babylon) and not a different Fold generation.
Back up everything: Fastboot flashing commonly requires a clean flash approach, so plan for a full data wipe (photos, chats, authenticator apps, work profiles).
Battery + cooling: Charge to 60%+ and keep the phone cool; overheating complaints after updates are common, and flashing should never be done on a hot device.
Use a reliable cable/port: Prefer a short, high-quality USB cable and a direct PC USB port (avoid loose hubs).
Drivers + MiFlash ready: Install Xiaomi/ADB drivers and Xiaomi Flash Tool on Windows, then extract the .tgz to a short folder path (e.g., C:\ROM\babylon\).
Verify MD5: Compare the downloaded file’s MD5 with 33c60fe88086802c4107861e94805e8d to reduce “corrupted ROM” flash failures.
