Download Xiaomi 15 Pro (haotian) HyperOS 3 Official ROMs
The Xiaomi 15 Pro, codename haotian, is Xiaomi’s China‑exclusive flagship with a 6.7‑inch 1440×3200 120 Hz AMOLED display, Snapdragon 8 Elite chipset, 12 GB LPDDR5X RAM, UFS 4.0 storage, a triple 50 MP camera system and IP68 rating for serious performance and durability. Its 6100 mAh silicon–carbon battery, 90 W wired charging and 50 W wireless charging make it a compact powerhouse for photography, gaming and 5G use.
At the same time, owners of the Xiaomi 15 series and related models report overheating after upgrading to HyperOS 3, faster battery drain than expected, brief performance drops and charging times that feel longer until the system finishes background optimizations. These issues are typical around major Android/HyperOS transitions and often improve once the phone is clean‑flashed to a stable build and allowed a few days to re‑index and learn usage patterns.
The official haotian HyperOS images below provide Android 16 HyperOS 3.0.5.0.WOBCNXM China Fastboot firmware plus a Xiaomi.eu custom ROM based on the same release, giving you tools to fix bootloops, revert failed mods and apply Xiaomi’s latest stability and security improvements. Flashing the correct ROM with Mi Flash Tool or Xiaomi.eu’s fastboot scripts can restore stock partitions, reduce software‑induced heating and battery drain, and keep your Xiaomi 15 Pro running at flagship‑class performance.

Flashing Requirements
- Back up all data: Fastboot and Xiaomi.eu flashes can erase apps and internal storage, so copy your photos, chats and documents first.
- Battery above 50%: A shutdown during flashing can corrupt partitions and permanently brick the phone.
- Windows PC & quality USB‑C cable: Needed for Mi Flash Tool, Xiaomi drivers and reliable fastboot communication.
- Unlocked bootloader: Complete Xiaomi’s official unlock procedure before flashing any haotian Fastboot or Xiaomi.eu ROM.
📱 Quick Flashing Guides
Method 1: Official HyperOS 3 Fastboot ROM (Mi Flash Tool)
- Prepare Mi Flash and ROM: Install Xiaomi USB drivers and Mi Flash Tool on your Windows PC, then extract haotian_images_OS3.0.5.0.WOBCNXM_… into a simple folder path.
- Unlock and enter fastboot: After unlocking the bootloader, power off the Xiaomi 15 Pro, hold Volume Down + Power to enter fastboot mode, and connect it via USB‑C.
- Load firmware in Mi Flash: Open Mi Flash, click Select, and point to the extracted haotian ROM folder containing the images and scripts.
- Choose “clean all”: Pick a mode such as “clean all” to refresh system partitions without auto‑relocking the bootloader mid‑flash.
- Flash and reboot: Click Flash, wait for Mi Flash to finish, and let the phone reboot; the first HyperOS 3 boot can take several minutes while the system optimizes in the background.
For detailed, step‑by‑step instructions (with screenshots) on using Mi Flash Tool for Xiaomi phones, see this full guide: Complete Guide: Flash Xiaomi Firmware with Mi Flash Tool.
Method 2: Xiaomi.eu HyperOS 3.0.5.0 (Fastboot Script / Recovery)
- Download and extract Xiaomi.eu ROM: On your PC, download xiaomi.eu_HAOTIAN_OS3.0.5.0.WOBCNXM_16.zip and extract it to reveal the fastboot batch/shell scripts and image files.
- Install platform‑tools: Set up Google’s Android platform‑tools so the fastboot command works in a terminal or command prompt.
- Enter fastboot with unlocked bootloader: Boot the Xiaomi 15 Pro into fastboot mode, connect it to the PC and confirm detection using fastboot devices.
- Run the Xiaomi.eu script: Execute the provided script (for example, a fastboot_*.bat) to flash the partitions automatically, carefully following the project’s instructions.
- First boot and optimization: After rebooting into Xiaomi.eu HyperOS 3, allow time for background optimization and monitor battery and thermals across several charging cycles.

Frequently Asked Questions (FAQs)
What Xiaomi 15 Pro problems can these ROMs help fix?
Flashing the correct haotian Fastboot ROM can fix soft‑bricks, bootloops after OTA updates, severe battery drain or heating tied to buggy HyperOS builds, and instability caused by failed mods or root attempts.
How do I confirm my Xiaomi 15 Pro uses the haotian firmware?
Check Settings → About phone → Version and look for Xiaomi 15 Pro with a build code containing “WOBCNXM” or use fastboot getvar product; official resources map haotian to Xiaomi 15 Pro China only.
Is HyperOS 3.0.5.0.WOBCNXM better for battery than older builds?
While results vary by user, Xiaomi’s newer HyperOS 3 builds focus on system stability and efficiency, and many devices see more consistent thermals and battery once background optimizations finish after updating.
Will flashing these ROMs erase my data?
Yes, Fastboot flashes using “clean all” and most Xiaomi.eu scripts wipe apps, accounts and internal storage, so always perform a full backup before installing any haotian_*_images_*.tgz or Xiaomi.eu ROM.
Can I install this China firmware on a non‑Chinese Xiaomi 15 variant?
The haotian WOBCNXM firmware is designed for the China‑only Xiaomi 15 Pro, and cross‑flashing it onto other models or regions can break cellular, updates or even brick the device, so it is strongly discouraged.
Is the Xiaomi.eu HyperOS 3.0.5.0 ROM official?
No, Xiaomi.eu ROMs are community projects that rebuild China firmware with extra languages and tweaks; they are popular among enthusiasts but not supported by Xiaomi and may affect warranty or security checks.
Why does my Xiaomi 15 Pro still run warm after updating?
After major HyperOS updates, the system runs background optimizations that temporarily increase heat and drain, and Xiaomi notes this should normalize in a few days; persistent extreme heating may indicate heavy apps or rare hardware issues that need further troubleshooting.
