Before You Begin ⚙️
- 💾 Backup data: Fastboot and custom ROM flashes usually wipe apps, accounts and internal storage; save photos and important files first.
- 🔋 Charge battery: Ensure your Xiaomi 14 Ultra has at least 50 % charge before flashing to avoid shutdowns and possible hard‑brick.
- 💻 Use a Windows PC & drivers: Install Xiaomi USB/ADB drivers and Android platform‑tools, and use a reliable USB‑C cable for Mi Flash or fastboot.
- 🔓 Unlock bootloader: Use Xiaomi’s official unlock tool and verify fastboot getvar product returns aurora before flashing any Fastboot ROM or xiaomi.eu build.
📱 How to Flash the Firmware
Method 1: Xiaomi Mi Flash Tool (Official Fastboot ROMs)
- Download & extract: Download the correct aurora_*_images_OS2.0.20x.0.VNA* or OS3.0.4.0.WNACNXM .tgz file for your region and extract it to a simple folder such as C:\ROM\aurora on your PC.
- Install Mi Flash & drivers: Install Xiaomi USB/ADB drivers and Mi Flash Tool on your Windows computer.
- Boot to fastboot: Power off the phone, hold Volume Down + Power until the fastboot screen appears, then connect it to the PC with a USB‑C cable.
- Flash the ROM: Open Mi Flash, click Select and choose the extracted ROM folder, select “clean all” (do not relock), then press Flash and wait until all partitions are written and a success message appears.
- Reboot & update: Let the phone reboot into HyperOS, complete setup and then check for newer OTA updates in Settings → About phone → System update.

Method 2: Fastboot Scripts & xiaomi.eu HyperOS 3
- Prepare tools & ROM: Install Android platform‑tools on your PC and download either an official Fastboot ROM or xiaomi.eu_AURORA_OS3.0.4.0.WNACNXM_16.zip, then extract it to reveal the images and .bat scripts.
- Connect in fastboot: Boot aurora into fastboot mode, connect to the PC and verify fastboot devices shows your phone.
- Run the script: For stock ROMs, run the flash_all.bat script that keeps the bootloader unlocked; for xiaomi.eu, use the provided “first install with data format” script for a clean install.
- Wait for flashing to finish: Do not disconnect the cable or close the window until the script completes and the device reboots or reports success.
- Finish setup & optimise: Complete Android setup, then debloat or limit background apps to help HyperOS 2/3 control heat and battery drain on Snapdragon 8 Gen 3.

Frequently Asked Questions (FAQs)
What issues can these HyperOS 2/3 ROMs fix on Xiaomi 14 Ultra?
Correctly flashing the regional Fastboot ROM can recover the phone from bootloops or failed OTAs and often solves HyperOS‑related lag, random reboots and some battery‑drain or stuttering issues caused by corrupted system files.
Should I stay on HyperOS 2 (Android 15) or move to HyperOS 3 (Android 16)?
HyperOS 2 is a mature Android 15 base, while HyperOS 3 Android 16 for Xiaomi 14 Ultra brings a refreshed UI, optimisations to address stutter and drain, new AI features and the latest security patches, so most users will benefit from upgrading once it is stable in their region.
What is the difference between WNACNXM and VNA* builds?
WNACNXM is the Chinese HyperOS 3 line for Xiaomi 14 Ultra, while VNA* codes (such as VNAMIXM, VNAEUXM, VNAINXM) identify Android 15 HyperOS 2 builds for Global, EEA, India, Russia, Taiwan and Turkey; you must match the suffix to your region.
Can these updates completely stop overheating on Xiaomi 14 Ultra?
HyperOS 3 focuses on better optimisation and can reduce unnecessary background load, but heavy 1.5K 120 Hz gaming and 5G will still push Snapdragon 8 Gen 3 to run hot, so using moderate graphics, stable Wi‑Fi and avoiding gaming while charging remains important.
Is it safe to flash China WNACNXM on a Global VNAMIXM device?
Cross‑flashing may boot with an unlocked bootloader, but it can break OTA updates, payments and region‑specific services and is risky if the bootloader is ever relocked, so sticking to the correct region code is strongly recommended.
How can I confirm my device is aurora before flashing?
Check the Version string in Settings → About phone (it should mention aurora and a VNA*/WNA* code) or run fastboot getvar product in fastboot mode; if the output is aurora, these ROMs are for your Xiaomi 14 Ultra.
