Flashing Requirements
- 💾 Backup data: Fastboot flashing will usually wipe apps, accounts and internal storage, so save photos and important files first.
- 🔋 Charge above 50 %: Ensure plenty of battery to avoid shutdowns and potential hard bricks during flashing.
- 💻 Windows PC & USB‑C cable: You need a Windows computer, Xiaomi USB/ADB drivers and a reliable cable for Mi Flash or fastboot.
- 🔓 Unlocked bootloader: Use Xiaomi’s official unlock procedure on MIX Fold 4 (goku) before flashing any goku_images_*.tgz file.
How to Flash the Firmware
Method 1: Xiaomi Mi Flash Tool (Fastboot ROM)
- Install tools & extract the ROM: Install Xiaomi USB drivers and Mi Flash Tool on your PC, then extract goku_images_OS3.0.3.0.WNVCNXM_… to a simple folder path without spaces or special characters.
- Enter fastboot mode on MIX Fold 4: After unlocking the bootloader, power off the phone, hold Volume Down + Power to enter fastboot, and connect the device via USB‑C.
- Load firmware into Mi Flash: Open Mi Flash Tool, click Select and point it to the extracted goku ROM folder that contains the partition images and scripts.
- Choose “clean all” and flash: In Mi Flash options, select “clean all” (do not relock), click Flash and wait patiently while all partitions are written.

Frequently Asked Questions (FAQs)
What MIX Fold 4 problems can OS3.0.3.0.WNVCNXM help fix?
This HyperOS 3 Fastboot ROM can recover MIX Fold 4 from bootloops, severe lag, failed OTAs and many software‑side bugs by reinstalling a clean Android 16 system image.
Is OS3.0.3.0.WNVCNXM only for China MIX Fold 4?
Yes. Firmware trackers clearly mark WNVCNXM as the China region code for MIX Fold 4 (goku), and it should not be flashed on global or EEA units that use different product codes.
Does HyperOS 3 on Android 16 fix HyperOS 2 battery drain?
HyperOS 3 brings updated security patches and system optimizations, and many users see more stable behaviour after a clean flash, but total battery life still depends on apps, signal quality and usage.
Can I install this China ROM on a non‑Chinese MIX Fold 4?
Cross‑flashing China firmware onto global hardware is risky and can break OTAs, local services and even cause bricks if the bootloader is relocked, so it is not recommended unless you fully understand the trade‑offs.
Why is the ROM so large at around 9 GB?
Foldables like the MIX Fold 4 ship with multiple high‑resolution displays, complex system apps and many built‑in features, so complete Fastboot images naturally occupy close to 9–10 GB.
Will I still receive OTAs after flashing this Fastboot ROM?
If you stay on the official WNVCNXM branch and do not modify system partitions, you should continue receiving Chinese OTA updates on MIX Fold 4 after flashing OS3.0.3.0.WNVCNXM.
