How to Flash Xiaomi 17 Ultra (nezha) OS3.0.10.0 Fastboot ROM
The nezha OS3.0.10.0 fastboot package is large and writes many partitions, so a stable PC, reliable USB‑C cable, and careful selection of options are essential to reduce the risk of soft brick or data loss.
Method 1 – Mi Flash Tool for nezha (Recommended)
This method uses Xiaomi’s flashing utility with a graphical interface and is the most suitable approach for most Xiaomi 17 Ultra China owners restoring the nezha fastboot ROM.
- Install Xiaomi USB drivers and Mi Flash Tool on a Windows PC, then extract
nezha_images_OS3.0.10.0.WPACNXM_20260111.0000.00_16.0_cn_6c8ff5bca5.tgzuntil you see the images and flash_all scripts inside a single folder. - Power off the Xiaomi 17 Ultra, hold Volume Down + Power to enter fastboot mode (fastboot logo), and connect it to the PC using a short, good‑quality USB‑C cable.
- Open Mi Flash Tool, click “Select,” and choose the root directory of the extracted nezha fastboot ROM folder that contains the configuration and partition images.
- Click “Refresh” so your nezha device appears in the list, then choose an option such as “clean all” for a full wipe; avoid “clean all and lock” unless this is the correct official China ROM for your original nezha unit and you understand the implications.
- Press “Flash” and wait until the progress bar reaches 100% and Mi Flash shows success; do not unplug the phone or close the tool until the Xiaomi 17 Ultra reboots into HyperOS 3.

Method 2 – Fastboot / flash.bat Script for nezha
The nezha fastboot ROM includes batch scripts that issue fastboot commands automatically and are meant for experienced users who are comfortable with a command‑line environment.
- Install Android platform‑tools (ADB and fastboot) on your computer and extract the nezha fastboot archive to a short path (for example
C:\nezha_OS3) with no spaces in the folder name. - Boot the Xiaomi 17 Ultra into fastboot mode (Volume Down + Power) and connect it to the PC, then run
fastboot devicesto confirm that the device ID is visible. - From inside the extracted ROM folder, run
flash_all.batfor a full clean flash,flash_all_except_storage.batto attempt keeping user data, orflash_all_lock.batonly when you are using the correct official China ROM and intend to re‑lock the bootloader. - Leave the Xiaomi 17 Ultra connected while the script flashes all relevant nezha partitions; the device should reboot automatically once the script ends without errors.
- On first boot into HyperOS 3, allow extra time for optimization of apps and system components, then confirm the OS3.0.10.0.WPACNXM build and Android 16 base in Settings > About phone.

Frequently Asked Questions
How do I verify that my phone is really Xiaomi 17 Ultra (nezha) before flashing?
From a PC with ADB, run adb shell getprop ro.product.device on a booted system or fastboot getvar product in fastboot mode; a Xiaomi 17 Ultra China unit should report a product string containing “nezha”.
Does this HyperOS 3 Android 16 ROM improve camera or AI features on Xiaomi 17 Ultra?
OS3.0.10.0.WPACNXM is a newer HyperOS 3 build that focuses on animations, resource management and assistant capabilities, so camera and AI behaviour should reflect Xiaomi’s tuning for that release rather than offer guaranteed performance “boosts” beyond official changelog expectations.
Is it safe to re‑lock the bootloader after flashing this fastboot ROM?
Re‑locking is only considered safe when using the correct official China ROM for your original nezha device; locking on a mismatched or modified build may trigger verified boot failures and can hard‑brick modern Xiaomi flagships.
