Flashing Requirements
- Xiaomi 15 Pro with codename haotian, verified in fastboot using fastboot getvar product or a trusted codename list.
- Unlocked bootloader for both the official fastboot TGZ and Xiaomi.eu ZIP; bootloader unlock is stricter on China‑only models.
- Windows PC, Xiaomi USB drivers, Mi Flash Tool, stable USB‑C cable and at least 20 GB free disk space.
- Battery at 60 % or higher because Snapdragon 8‑class chips already generate heat under load and during major updates.
- Full backup of photos, messages and app data; “clean all” flashes and custom ROM installs wipe internal storage.
How to Flash the Firmware
Fastboot TGZ – Official China OS3.0.5.0
- Download haotian_images_OS3.0.5.0.WOBCNXM…, then extract it until the images folder and flash_all*.bat scripts appear.
- Install Xiaomi USB drivers and Mi Flash Tool, open Mi Flash and point it to the extracted firmware directory.
- Boot the phone into fastboot mode, connect via USB and click “Refresh” to confirm it is detected.
- Select “clean all” (recommended for unbrick or moving to Android 16), click “Flash” and wait for a success message without unplugging.
- Reboot; the first HyperOS 3 boot may run hot and drain more than usual while background optimizations finish over the next day or two.
Xiaomi.eu OS3.0.5.0 ZIP – Custom ROM
- Unlock the bootloader, install a compatible custom recovery and copy the Xiaomi.eu ZIP to internal storage.
- Boot into recovery, back up your current system and wipe data/cache (and system if recommended by Xiaomi.eu).
- Flash the Xiaomi.eu ZIP, wait for completion, then reboot into system.
- Set up your Google account, restore apps and monitor thermals and battery over several days, as some users report smoother behavior after debloating and tuning.

Frequently Asked Questions (FAQs)
What does HyperOS 3.0.5.0.WOBCNXM change on Xiaomi 15 Pro?
The official changelog for OS3.0.5.0 mainly mentions updating the security patch to November 2025 and improving system security, building on earlier HyperOS 3.0.3.0 features like AI DeepThink tools and better recorder functions.
Will this update fix my heating and battery drain issues?
HyperOS 3 security and stability updates can smooth performance, but Xiaomi notes that multiple background apps, high brightness and heavy tasks are still key reasons for heat and drain, so tuning settings and doing a clean flash often matters more than the build alone.
Can I use the China ROM on a non‑Chinese Xiaomi 15?
Haotian builds are for the China‑only 15 Pro; global Xiaomi 15 (dada) uses different firmware and mixing them can break network features or OTA behavior, so only experienced users who understand the risks should consider cross‑flashing.
How can I confirm my device is really codename haotian?
Boot into fastboot mode and run fastboot getvar product on a PC; Xiaomi 15 Pro should return haotian, matching Xiaomi’s codename references and firmware portals for this model.
