Flashing Requirements
- Windows PC with Xiaomi USB drivers installed, Mi Flash Tool set up and at least 20 GB free space for extracting the fastboot ROM.
- Officially unlocked bootloader on the Redmi K80 Ultra (via Xiaomi’s unlock tool) before attempting any fastboot flash.
- Good quality USB‑C cable and a stable USB port; avoid unreliable hubs that may cause disconnections during flashing.
- Battery level of at least 50–60 % because a shutdown mid‑flash can leave the phone hard‑bricked.
- Full backup of photos, chats and documents, since the recommended “clean all” procedures will erase internal storage and user data.
How to Flash the Firmware
Quick steps – Mi Flash Tool (fastboot TGZ ROM)
- Download the dali_images_OS3.0.4.0.WONCNXM… file and extract it until you see the images folder plus flash_*.bat scripts.
- Open Mi Flash Tool, click “Select” and point it to the extracted firmware directory containing the configuration and images.
- Boot Redmi K80 Ultra into fastboot mode, connect it to the PC and press “Refresh” in Mi Flash to confirm it is detected.
- Choose “clean all” (recommended for major Android upgrades) and click “Flash”, waiting until Mi Flash shows a green success status.
- Reboot the phone; first boot into Android 16 / HyperOS 3 can take several minutes while the system optimizes apps and data.

Frequently Asked Questions (FAQs)
What issues can OS3.0.4.0.WONCNXM fix on Redmi K80 Ultra?
The full fastboot ROM can recover phones stuck in bootloops, suffering from failed OTAs, or destabilized by root/custom mods by rewriting all critical partitions with a clean Android 16 / HyperOS 3 build. It also delivers Xiaomi’s latest HyperOS 3 performance and AI improvements, which aim to smooth animations and reduce background glitches seen on some earlier HyperOS releases.
Will updating to HyperOS 3 improve battery life and performance?
Xiaomi advertises HyperOS 3 as offering more efficient performance tuning and better cross‑device optimization, which can help with lag and random battery drain on supported devices. However, user reports across HyperOS suggest results vary; a clean flash and careful app management usually give the best chance of stable battery life.
Does this China ROM include Google apps and full global languages?
WONCNXM is a China channel ROM focused on Chinese and a limited set of other languages, and it does not normally bundle the full Google app suite out of the box. Google services can usually be added later, but OTA updates will continue on the China track and some global‑only features may be missing.
Can I use this ROM to convert from a global ROM to China ROM?
Many power users cross‑flash between China and global firmwares after unlocking the bootloader, but doing so carries risks such as mismatched OTAs, SafetyNet/Widevine changes and region‑specific bugs. Unless you have a clear reason and know how to recover from problems, staying on the original region channel is safer for long‑term stability.
