How to Update Xiaomi Yi Action Camera Firmware in 2026: A Complete Guide

Let me tell you a story. A few years ago, I was hiking in the Rockies, capturing breathtaking views with my trusty Xiaomi Yi Action Camera. Midway through the trip, I noticed the footage was stuttering, the battery drained faster than expected, and the Wi-Fi connection kept dropping. Frustrated, I almost packed it away—until a fellow hiker casually mentioned, “Did you check if the firmware’s up to date?”

That simple question saved my trip. Updating the firmware fixed all the issues. The camera ran smoother, the battery lasted longer, and the app connected instantly. Since then, I’ve made it a habit to check for firmware updates before every adventure. If you own a Xiaomi Yi Action Camera (or are considering one), staying current with firmware isn’t just a “nice-to-have”—it’s essential. In 2026, with new features, security patches, and performance tweaks rolling out regularly, updating your camera ensures you’re getting the best possible experience. And the good news? It’s easier than you think. Whether you’re a tech newbie or a seasoned user, this guide will walk you through every step, with tips, tricks, and real-life examples to make the process painless.

Why Updating Your Xiaomi Yi Firmware Matters

Before we dive into the “how,” let’s talk about the “why.” Firmware is the built-in software that controls your camera’s hardware. Think of it as the brain behind the lens. Without updates, your camera is stuck in time—missing out on new features, bug fixes, and security upgrades. Here’s what you gain (or lose) depending on your update habits.

Performance and Stability Improvements

Firmware updates often address performance hiccups. For example, the Yi 4K+ had early reports of overheating during 4K recording. A 2023 update reduced heat generation by 15%, according to Yi’s release notes. Similarly, older models like the Yi Lite saw smoother Wi-Fi streaming after a 2022 patch. These aren’t minor tweaks—they’re game-changers for reliability.

New Features and Modes

Updates can add entirely new capabilities. In 2024, the Yi Horizon (a newer model) gained a “TimeWarp 3.0” mode via firmware, letting users create stabilized hyperlapses with one tap. Even older cameras like the Yi 4K received “Auto Low Light” mode in a 2025 update, improving night footage without manual settings.

Security and Compatibility

Outdated firmware can expose your camera to vulnerabilities—especially if you use Wi-Fi or Bluetooth. A 2021 update patched a critical security flaw in the Yi App that could let hackers access your footage. Plus, newer smartphones and apps may not support older firmware versions. For instance, the 2026 Yi App requires firmware v3.2+ for full functionality.

Real-World Example: The Overheating Fix

Take my friend Alex, who owns a Yi 4K. Before updating, their camera would shut down after 10 minutes of 4K recording. After installing the 2024 firmware, it handled 20+ minutes of continuous recording without issues. That’s the power of updates—they turn “almost unusable” into “ready for adventure.”

Preparing for the Update: What You’ll Need

Updating firmware isn’t a plug-and-play process. You’ll need the right tools and prep work to avoid headaches. Here’s your checklist.

1. Check Your Current Firmware Version

First, verify what firmware your camera is running. This helps you determine if an update is necessary and which version to install. Here’s how:

• Turn on your camera.
• Go to Settings > General > About Camera.
• Look for “Firmware Version” (e.g., v2.8.1).

Pro Tip: If your camera is older than 2020, check the model number (printed on the back) to ensure you’re downloading the correct update. The Yi 4K (2016) and Yi 4K+ (2017) have different firmware, despite similar names.

2. Gather the Required Tools

You’ll need:

• A fully charged camera (or plugged into a power source). A dead battery mid-update can brick your device.
• A high-speed microSD card (16GB+ recommended). The update file is typically 50–100MB, but you’ll need space for temporary files.
• A computer (Windows, Mac, or Linux) to download and transfer files.
• A stable internet connection (Wi-Fi or Ethernet). Avoid public networks to prevent corruption.

3. Backup Your Settings and Footage

While updates rarely affect stored data, it’s safer to:

• Transfer existing footage to your computer.
• Note down custom settings (e.g., resolution, exposure) in case they reset.
• Format the SD card after backing up (see next section for why).

Caution: Never skip the backup step. A friend once lost 32GB of footage when their SD card failed during an update. Don’t be that person.

Step-by-Step: Updating Firmware via SD Card (Offline Method)

The SD card method is the most reliable—especially if you’re in an area with spotty Wi-Fi. It’s also the only way to update older models like the Yi Lite or Yi 4K (2016). Here’s how to do it.

Step 1: Download the Correct Firmware

1. Visit the official Xiaomi Yi support site (e.g., yitechnology.com/support). Avoid third-party sites—they may host outdated or malware-infected files.
2. Navigate to “Firmware” or “Downloads.”
3. Select your camera model from the dropdown menu. Double-check the model number!
4. Download the latest firmware file (usually named firmware.bin or similar).

Example: For the Yi 4K+, the 2026 firmware is v3.4.2, released on January 15, 2026. The file size is 78MB.

Step 2: Prepare the SD Card

1. Insert the SD card into your computer (use an adapter if needed).
2. Back up any files, then format the card to FAT32. This is critical—NTFS or exFAT can cause errors.
   • On Windows: Right-click the SD card > “Format” > Select “FAT32.”
   • On Mac: Use Disk Utility > “Erase” > Choose “MS-DOS (FAT).”
3. Create a folder named YI (all caps) in the root directory.
4. Place the downloaded firmware.bin file inside the YI folder.

Pro Tip: Use a card reader instead of connecting the camera via USB. It’s faster and reduces the risk of connection drops.

Step 3: Install the Update

1. Power off your camera.
2. Insert the prepared SD card.
3. Hold the Wi-Fi button (or Mode button on older models) while turning on the camera.
4. Wait for the LED to flash rapidly (this means the update is starting).
5. Do not turn off the camera or remove the SD card until the LED stops flashing (usually 3–5 minutes).
6. Once complete, the camera will restart automatically.

Troubleshooting: If the LED doesn’t flash, double-check:

• Is the SD card formatted correctly?
• Is the firmware file in the YI folder?
• Is the battery charged?

Step 4: Verify the Update

1. After restarting, go to Settings > General > About Camera.
2. Confirm the firmware version matches the downloaded file (e.g., v3.4.2).
3. Test key features (e.g., 4K recording, Wi-Fi) to ensure they work.

Updating via the Yi App (Online Method for Newer Models)

If you own a newer Yi camera (e.g., Yi Horizon, Yi 4K+ with Wi-Fi 6), you can update directly through the Yi App. This method is faster but requires a stable internet connection.

Step 1: Connect Camera to the Yi App

1. Download the Yi Action Camera App (iOS/Android).
2. Turn on your camera and enable Wi-Fi (hold the Wi-Fi button until it flashes).
3. Open the app and tap “Connect to Camera.”
4. Follow the on-screen prompts to pair the devices.

Note: Older models (pre-2020) may not support app updates. Use the SD card method instead.

Step 2: Check for Updates

1. In the app, tap the camera icon (top-left).
2. Go to Settings > Firmware Update.
3. If an update is available, you’ll see a notification like “New firmware v3.4.2 is ready.”
4. Tap “Download & Install.”

Pro Tip: Use Wi-Fi 5/6 or Ethernet (via a hotspot) for faster downloads. The update may take 5–10 minutes.

Step 3: Monitor the Process

1. The app will show a progress bar.
2. Do not close the app or use your phone for other tasks. Interruptions can corrupt the update.
3. When complete, the camera will restart. The app will confirm success.

Step 4: Post-Update Checks

1. Verify the firmware version in the app (under Settings).
2. Test new features (e.g., if the update added “Super Night Mode,” try it in low light).
3. Reset Wi-Fi settings if the camera disconnects (go to Settings > Network > Forget Wi-Fi).
