Xiaomi 15 Ultra is Xiaomi’s 2025 flagship camera phone built around the Snapdragon 8 Elite (SM8750‑AB) 3 nm chipset, pairing an octa‑core CPU and Adreno 830 GPU with up to 16 GB LPDDR5X RAM and 1 TB UFS 4.0 storage for heavy gaming and imaging workloads. It features a 6.73‑inch high‑resolution display, a large battery with very fast wired and wireless charging, advanced Leica‑branded cameras and launches on Android 15 with HyperOS 2.
Across HyperOS devices, users and reviewers frequently mention heat under load, aggressive battery drain after some updates, and random UI or notification bugs, so a clean flash with official images is often used to fix bootloops, software corruption or unstable performance.
The xuanyuan fastboot packages below include the latest China Android 16 HyperOS 3.0.6.0 release plus multiple Android 15 HyperOS 2.0.20x regional ROMs and a Xiaomi.eu OS3.0.6.0 community build to help you repair, update or customize your Xiaomi 15 Ultra safely.

Flashing Requirements
- Windows PC with Xiaomi USB drivers and Mi Flash Tool installed, and at least 25 GB of free space for the large xuanyuan fastboot packages.
- Unlocked bootloader on Xiaomi 15 Ultra for all fastboot TGZ and Xiaomi.eu ZIP flashes; locked devices should rely on stock OTA/recovery updates instead.
- Good USB‑C cable connected directly to a stable motherboard USB port (avoid unstable hubs) to prevent disconnections during flashing.
- Battery charged to at least 50–60 % to avoid shutdown while flashing, which can result in severe or permanent bricks.
- Full backup of internal storage, including photos, chats and 2FA apps, because “clean all” modes and most custom ROM installs will wipe user data.
How to Flash the Firmware
Quick steps – Mi Flash Tool (official TGZ fastboot ROMs)
- Download the correct xuanyuan_…_images_… .tgz for your region (China, Global, RU, ID, EEA, TW, TR or IN) and extract it until you see the images folder and flash_all*.bat scripts.
- Open Mi Flash Tool, click “Select” and choose the extracted firmware directory containing the configuration files and partition images.
- Boot Xiaomi 15 Ultra into fastboot mode, connect it via USB and click “Refresh” to verify that the device is detected by Mi Flash.
- Select the “clean all” option (recommended for unbricking or Android 16 upgrades) and press “Flash”, then wait until Mi Flash reports a successful result.
- Reboot and complete setup; first boot can take several minutes while HyperOS optimizes apps and re‑builds caches.
Quick steps – fastboot script / Xiaomi.eu ZIP
- For official TGZ ROMs, open a command window in the extracted ROM folder; for Xiaomi.eu, copy the ZIP to device storage or follow that project’s recovery/fastboot instructions.
- Enter fastboot mode on the phone, connect it and confirm detection with fastboot devices on your PC.
- Run flash_all.bat (or another script provided) for official ROMs, or flash the Xiaomi.eu ZIP from a compatible custom recovery/fastbootd environment as documented by that project.
- Wait for all commands or recovery steps to finish; do not disconnect the cable or force‑reboot until the process completes without errors.
- Reboot to system and test network, cameras and battery behavior; if you still notice severe heat or drain, consider a factory reset and review installed apps and settings.

Frequently Asked Questions (FAQs)
What issues can these ROMs fix on Xiaomi 15 Ultra?
Full xuanyuan fastboot ROMs can revive phones stuck in bootloops, fix devices that no longer boot after failed OTAs or root/custom ROM experiments, and resolve many app‑crash or stability problems caused by corrupted system partitions. They also provide a clean way to move China units from Android 15/HyperOS 2 to Android 16/HyperOS 3 using OS3.0.6.0.
Should I use China OS3.0.6.0 or stay on a global OS2.0 build?
China OS3.0.6.0.WOACNXM delivers Android 16 and HyperOS 3 features, but it is intended for China models and comes without full Google integration by default. Global VOAXXM ROMs keep Android 15 but match original region settings, languages and services, so they are usually safer for international devices that shipped with global firmware.
Will these updates fix heating and battery drain completely?
HyperOS 2 and 3 maintenance builds include kernel, scheduler and power‑tuning changes that can reduce random lag and abnormal drain, but heavy camera or gaming workloads will still push Snapdragon 8 Elite devices to high temperatures. Good cooling, realistic graphics settings and sensible charging habits are still important even on the latest firmware.
Does OS3.0.6.0 China ROM include Google apps and all languages?
China WOACNXM builds primarily target the Chinese market, offering Chinese and English plus a limited set of additional languages and usually shipping without pre‑installed Google Mobile Services. You can typically add Google apps later, but OTAs will continue on the China channel and some global‑only services or region features may not be available.
How can I confirm my 15 Ultra really uses codename xuanyuan?
In fastboot mode, you can run fastboot getvar product and check that the output is xuanyuan, which matches Xiaomi’s own firmware portals and codename lists for Xiaomi 15 Ultra. If a different codename appears, do not flash these files, as they are not intended for your device.
