Flashing Requirements
- Backup all data: Fastboot flashing can fully wipe apps, photos, and internal storage, so back up to PC or cloud first.
- Charge the phone: Keep your Redmi K80 Ultra at 50–60 % or higher battery to avoid shutdown during flashing.
- Use a Windows PC: Install Xiaomi/MediaTek USB drivers and use a high‑quality USB‑C cable for a stable connection.
- Confirm model and codename: In Settings → About phone, verify this is Redmi K80 Ultra China with codename
dali, not another Redmi K80 variant. - Unlock the bootloader (if required): For manual fastboot/Mi Flash usage, you usually need an officially unlocked bootloader; OTA/recovery updates do not require this.
How to Flash the Firmware
Method 1: Xiaomi Mi Flash Tool (Fastboot ROM)
- Prepare tools and files: On your Windows PC, install Xiaomi USB drivers, set up the Xiaomi Mi Flash Tool, and extract
dali_images_OS3.0.4.0.WONCNXM_20251105...to a folder with the fastboot images. - Load the firmware: Open Mi Flash Tool, choose the firmware directory you extracted, and let the tool load all partition images automatically.
- Enter fastboot mode: Power off the phone, then hold Volume‑Down + Power to enter fastboot mode and connect the device to your PC with a USB‑C cable.
- Start flashing: In Mi Flash, make sure the device is detected, select a safe option such as “clean all”, and start the flashing process; wait patiently until the tool reports a successful flash.
- First boot on HyperOS 3: Disconnect the phone, reboot it normally, and allow several minutes for the first boot while HyperOS 3.0.4.0 optimizes apps and system resources.

Method 2: Fastboot Script (flash_all.bat)
- Set up platform tools: Install Android platform‑tools on your PC, then extract the fastboot ROM so that
flash_all.bat(or equivalent script) and image files are in the same folder. - Connect in fastboot: Boot Redmi K80 Ultra into fastboot mode, connect via USB, and confirm detection with a
fastboot devicescommand from your PC. - Run the script: Execute
flash_all.bat(or your chosen script) to flash all necessary partitions automatically, and avoid interacting with the device until it finishes. - Wait for completion: The script will write system, vendor, boot, and other partitions, then reboot the device; interrupting this process may cause a soft brick.
- Set up and test: After booting into HyperOS 3.0.4.0.WONCNXM, complete initial setup, restore your backups, and test for improvements in temperature, battery life, and overall smoothness.

Frequently Asked Questions (FAQs)
What Redmi K80 Ultra problems can this firmware help fix?
This official HyperOS 3.0.4.0.WONCNXM build can resolve many software-related issues such as random freezes, bootloops after OTA updates, laggy UI, and some causes of overheating by installing a clean, optimized system. It also incorporates earlier HyperOS 3 fixes that improved notification delivery, status-bar and control-center behavior, battery stats, and Bluetooth stability.
Can OS3.0.4.0.WONCNXM reduce overheating and battery drain?
High battery drain and heating under load are common complaints for Redmi K80 Ultra owners, especially during gaming, charging, or extended camera use. HyperOS 3.0.4.0 focuses on better compiler optimizations, smarter frequency scheduling, and more efficient memory and graphics handling, which together can noticeably improve thermals and screen‑on time when combined with sensible usage.
Will flashing this fastboot ROM erase my data?
Using Mi Flash Tool or a full flash_all.bat script with this fastboot package usually performs a clean installation, which wipes user apps, internal storage, and settings. Always assume that manual fastboot flashing may result in complete data loss and make full backups before starting.
How do I verify that this firmware is compatible with my phone?
You must confirm that your device is the China-only Redmi K80 Ultra, that its codename is dali, and that it is on the China HyperOS branch (WONCNXM) before flashing. Global, India, or other regional K80 variants must use their own dedicated firmware builds, and flashing this China ROM on the wrong device can cause serious problems.
Can this ROM unbrick a soft-bricked Redmi K80 Ultra?
If the phone still enters fastboot mode and the bootloader is unlocked, a full fastboot flash of dali_images_OS3.0.4.0.WONCNXM... often recovers devices stuck on the boot logo, HyperOS animation, or a crash loop after a failed update. Devices that cannot access fastboot or show no signs of life usually need professional repair via EDL or service tools rather than home flashing.
Is it worth upgrading from HyperOS 2.x or early HyperOS 3 builds?
Compared with initial HyperOS 2 and early HyperOS 3 pilot releases, OS3.0.4.0.WONCNXM delivers a more mature Android 16 base with refined performance, stability, and cross‑device features. For long‑term security, app compatibility, and smoother everyday experience on Redmi K80 Ultra, updating to a stable build like this is strongly recommended if you follow safe flashing practices.
