Xiaomi MIX Flip 2 (bixi) Android 16 HyperOS 3 Fastboot ROM Download
The Xiaomi MIX Flip 2 is Xiaomi’s second‑generation clamshell foldable, launched in mid‑2025 with a flagship Snapdragon‑class platform, premium cameras and HyperOS 2 based on Android 15 for the Chinese market. Early HyperOS users across Xiaomi devices report issues like occasional animation stutter, background apps being killed too aggressively, and higher than expected power draw during short‑video and social‑media use, which can also affect a performance‑oriented foldable like the MIX Flip 2.
The bixi_images_OS3.0.3.0.WOHCNXM fastboot ROM is the first stable Android 16 / HyperOS 3 firmware for MIX Flip 2 (codename bixi), bringing deep performance optimizations, smoother animations, and updated AI features while fixing bugs from earlier HyperOS 2 builds.

CRUCIAL WARNING: This fastboot ROM is strictly for Xiaomi MIX Flip 2 devices with codename bixi and China region firmware; it must not be flashed to other MIX, Xiaomi 15‑series, Redmi or POCO models, or to future MIX Flip variants with different codenames, because cross‑flashing can permanently brick the phone.
The build code WOHCNXM identifies a China CNXM release, so you should only use this package on Chinese MIX Flip 2 units that originally shipped with CN firmware; flashing it over any future global/EEA variants may lead to network, language or service‑compatibility issues and broken OTA updates.
All official bixi_images_*.tgz fastboot packages will wipe user data when flashed with Xiaomi’s tools, and choosing aggressive options like “clean all and lock” with a mismatched setup can relock the bootloader on an unsupported ROM and cause boot, account‑binding or Google‑service problems.
Download Firmware for Xiaomi MIX Flip 2 (bixi)
Because this is the first stable Android 16 / HyperOS 3 fastboot ROM for MIX Flip 2, it is the recommended baseline for Chinese units that need a clean, fully updated system image rather than incremental OTA patches. Users coming from heavily customized or buggy HyperOS 2 installs will benefit the most from a full fastboot flash of this build.

Preparation Before Flashing
Click here for the MIX Flip 2 (bixi) pre‑flash checklist
- Confirm exact device and codename: Boot into fastboot mode and run fastboot getvar product from your PC to confirm it returns bixi, and check in Settings > About phone that your build string is a China CNXM variant before downloading this ROM.
- Backup your data: Fastboot flashing will erase apps, messages and settings, so back up important data (photos, chats, authenticator codes) to Mi Cloud, Google or an external drive before starting.
- Unlock the bootloader: Xiaomi fastboot ROMs require an unlocked bootloader; use the official Mi Unlock tool on a Windows PC, noting that the unlock itself also wipes user data.
- Install drivers and tools: Install Xiaomi USB drivers, ADB/Fastboot and the latest Mi Flash / Xiaomi Flash Tool, then extract the bixi_images_…tgz package to a short path such as C:\bixi_OS3.0.3.0.
- Charge and use a quality cable: Charge the MIX Flip 2 to at least 50% and use a reliable USB‑A to USB‑C or USB‑C to USB‑C cable connected directly to your PC, avoiding hubs or loose ports.

Frequently Asked Questions (FAQs)
- Q1. Who should install this OS3.0.3.0.WOHCNXM fastboot ROM on MIX Flip 2?
- This ROM is ideal for Chinese MIX Flip 2 owners who want a clean upgrade from HyperOS 2 (Android 15) to HyperOS 3 (Android 16), or who need to fix persistent bugs like random freezes, animation glitches or abnormal battery drain that survived OTA updates.
- Q2. What real improvements does HyperOS 3 bring compared to HyperOS 2 on MIX Flip 2?
- The official changelog emphasizes refined compiler instructions, better memory management, improved CPU frequency scheduling and new rendering logic, which together should make folding animations, app switching and camera use feel smoother while reducing overall power draw. It also enhances Recorder, travel assistant, messaging and child mode, so day‑to‑day usability is upgraded alongside raw performance.
- Q3. Can this Chinese ROM be flashed on a future Global/EEA MIX Flip 2 to get Android 16 early?
- While cross‑flashing is sometimes technically possible on Xiaomi devices with the same codename, doing so between China and Global/EEA firmwares can break region‑specific features, change default languages and disrupt OTA behavior, and is not recommended for typical users. It is safer to wait for a matching WO**MIXM/WO**EUXM build designed for your region if and when global MIX Flip 2 variants are released.
- Q4. Will flashing this ROM fix my MIX Flip 2’s battery drain or heat issues?
- HyperOS 3 for MIX Flip 2 specifically mentions power‑use and short‑video efficiency optimizations, which should help with mild to moderate drain and warmness caused by OS‑level inefficiencies. However, heavy gaming on a thin foldable will still generate heat, so you may also need to cap frame rates or graphics settings in demanding titles.
- Q5. Is the camera quality changed by this firmware?
- The public changelog for OS3.0.3.0.WOHCNXM focuses more on performance, AI tools and system UX than on major camera algorithm overhauls, so you should expect consistency with late HyperOS 2 behavior rather than dramatic changes. Minor tuning to processing and stability is still possible, but Xiaomi has not promoted any headline camera features tied solely to this build.
- Q6. What is the safest flashing option in Mi Flash for this ROM?
- For most users, “clean all” is the safest choice, as it fully refreshes the system while keeping the bootloader unlocked, which simplifies recovery if you ever need to re‑flash. Avoid “clean all and lock” unless you are returning to the tablet’s original region/branch, because relocking on a mis‑matched setup can cause boot or account‑locking issues.
