Xiaomi MIX Flip, codename ruyi, is a premium clamshell foldable with Snapdragon 8‑series power, dual high‑refresh OLED screens, Leica‑branded cameras and a 4,780 mAh battery with 67 W fast charging, aimed at users who want flagship performance in a compact flip form.
Reviews and user reports praise its screens, battery life and speed, but also point out weak water protection, a hinge that feels less solid than rivals, thermal throttling under load and laggier animations after some HyperOS updates.
The official HyperOS fastboot ROMs below – including a China HyperOS 3 Android 16 build and multiple Android 15 HyperOS 2 regional ROMs – let you clean‑flash your MIX Flip to fix software corruption, reduce lag and benefit from Xiaomi’s latest performance and stability optimizations.

Flashing Requirements
- MIX Flip must report ruyi in fastboot (fastboot getvar product) before using these fastboot ROMs.
- Bootloader has to be unlocked; Xiaomi fastboot packages cannot be flashed on a locked MIX Flip.
- Windows PC with Xiaomi USB drivers, Xiaomi Mi Flash Tool (or fastboot CLI), good USB‑C cable and at least 15–20 GB free space.
- Battery charged to 60 % or higher to reduce the risk of shutdown and extra throttling during the flash.
- Full backup of photos, messages and app data, as “clean all” fastboot flashes will wipe internal storage.
How to Flash the Firmware
Fastboot ROMs (.tgz) with Xiaomi Mi Flash Tool
- Download the correct regional ruyi_…_images_… `.tgz` and extract it until the de>images folder and flash_all*.bat scripts appear.
- Install Xiaomi USB drivers and Mi Flash Tool on your PC, open Mi Flash and select the extracted firmware folder.
- Boot MIX Flip into fastboot mode, connect via USB and click “Refresh” in Mi Flash to ensure the device is recognized.
- Choose the clean all option, click “Flash” and wait patiently until Mi Flash reports success; do not disconnect the cable early.
- Reboot and let HyperOS finish optimisation; HyperOS 3.0.3.0 in particular includes deeper performance tuning and smoother animations that can reduce lag from previous builds.

Frequently Asked Questions (FAQs)
What issues can these ruyi ROMs actually fix?
Clean fastboot ROMs can revive MIX Flip units stuck on the logo, repair failed HyperOS updates and clear deep software glitches that cause freezes or UI lag, giving you a fresh Android 15 or 16 base.
Will HyperOS 3.0.3.0 stop overheating and throttling?
The OS3.0.3.0 changelog emphasizes improved scheduling, memory handling and graphics efficiency, but Xiaomi still warns that flip phones heat faster when folded and will throttle to protect the hardware, so long gaming sessions may still warm the device.
Which region should I pick for my MIX Flip?
China devices should use WNICNXM, while global, EEA, Taiwan and Russia units must match VNIMIXM, VNIEUXM, VNITWXM or VNIRUXM respectively to keep correct language packs, bands and OTA behaviour.
