Xiaomi 12 Pro Dimensity (daumier) HyperOS 1 Fastboot ROM & Xiaomi.eu MIUI 14 Fastboot ROM (Android 14 / 13)
Xiaomi 12 Pro Dimensity Edition delivers a flagship‑level experience with a high‑refresh AMOLED display, powerful Dimensity chipset, fast charging and premium build, tailored for demanding apps, gaming and camera use. As devices age, users often encounter issues such as lag after many incremental updates, random app crashes, failed OTAs or soft‑bricks when testing custom ROMs, especially on performance‑oriented phones like this.
This page is prepared after reviewing HyperOS 1.0 firmware trackers, Xiaomi 12 Pro Dimensity (daumier) MIUI/HyperOS ROM archives and Xiaomi.eu releases, so each package here is confirmed for Xiaomi 12 Pro Dimensity (codename daumier) only, covering one official HyperOS 1 Fastboot ROM and one Xiaomi.eu MIUI 14 Android 13 fastboot‑style ROM.

The battery should be charged to at least 50%, and the USB connection must remain stable throughout flashing to avoid corruption or hard‑brick.

HyperOS and firmware portals label OS2.0.6.0.ULGCNXM as a China HyperOS 1.0 Android 14 Stable release for “Xiaomi 12 Pro Dimensity (daumier)” and list the matching daumier_images_OS2.0.6.0.ULGCNXM_... Fastboot ROM.
Can Global Xiaomi 12 Pro or other 12‑series devices flash this daumier OS2.0.6.0.ULGCNXM ROM?
No; codename lists distinguish daumier from other Xiaomi 12 Pro variants, and the ROM is flagged for the Dimensity Edition only; cross‑flashing between different codenames and hardware is not recommended.
What is the difference between OS2.0.6.0.ULGCNXM and Xiaomi.eu_multi_DAUMIER_V14.0.4.0.TLGCNXM_v14-13-fastboot.zip?
The former is an official China HyperOS 1 Android 14 Fastboot ROM, while the latter is a Xiaomi.eu custom MIUI 14 Android 13 ROM based on V14.0.4.0.TLGCNXM, with added languages and modifications.
Does flashing the HyperOS 1 Fastboot ROM on Xiaomi 12 Pro Dimensity wipe all data?
Fastboot ROM and flash_all.bat procedures are documented as clean installs that usually erase user data, so backups are strongly advised before installing OS2.0.6.0.ULGCNXM.

No; Xiaomi.eu ROMs are community builds based on stock bases, and the DAUMIER V14.0.4.0 MIUI 14 package is described as a custom ROM, not an official Xiaomi firmware.
Will updating from Xiaomi.eu MIUI 14 to official HyperOS 1 via Fastboot cause problems?
