Xiaomi 12 Pro Dimensity (daumier) HyperOS 2 Android 14 Fastboot ROM Download – OS2.0.6.0.ULGCNXM (China)

[Daniel]

This page provides the official HyperOS 2 Android 14 Fastboot ROM for the Xiaomi 12 Pro Dimensity Edition with codename daumier, along with a popular xiaomi.eu MIUI 14 fastboot ROM based on the China build. Owners of the Dimensity version report issues such as random lag, thermal throttling under heavy loads, battery drain after updates, and occasional software glitches, which sometimes improve after a clean re‑flash of the correct stock firmware. This article helps you identify the right firmware, understand what HyperOS OS2.0.6.0.ULGCNXM changes, and choose between pure stock and a community xiaomi.eu ROM for your Xiaomi 12 Pro Dimensity.

• Never flash firmware for the Snapdragon Xiaomi 12 Pro or any other model on the Dimensity Edition; mixing variants can permanently brick the device.
• Only use ROMs explicitly marked for codename daumier and China branch ULGCNXM to avoid modem or bootloader mismatch.
• Fastboot flashing and switching between HyperOS and xiaomi.eu can wipe all user data, so a full backup is strongly recommended before proceeding.
• Anti‑rollback and security mechanisms may block downgrades; do not attempt to flash older Android or firmware versions unless they are confirmed safe for your current bootloader state.

• Windows PC with ADB/Fastboot drivers correctly installed.
• USB cable in good condition (avoid any disconnections during flashing).
