How to Update Xiaomi Earphones 2: Official and Alternative Ways

Xiaomi Earphones 2 wireless headphones (TWSEJ04LS model) regularly receive firmware updates that improve sound, connection stability and battery life. However, the update process often raises questions about where to download firmware, how to avoid bugs, and what to do if the headphones “hang” during the upgrade. This article provides a complete guide to current ways for 2026, including official methods through Mi Fit/Mi Home and alternative solutions for power users.

It’s important to understand that the firmware update for the Earphones 2 is different from the process for other Xiaomi models (such as the AirDots Pro or Buds 4). There is no separate PC software, and all manipulations are performed via a smartphone. While the wrong interruption of the process can lead to the “bricking” of the headphones – their refusal to turn on or constant reboots. We will discuss how to minimize risks and what to do in the event of a failure.

Preparing for an update: checking the current version and compatibility

Before you upgrade to Xiaomi Earphones 2, make sure your model supports the new firmware. Some headphone versions (for example, for the Chinese market) may have limitations.

1. Connect the headphones to the smartphone via Bluetooth.
2. Open the Mi Fit app (or Mi Home for Chinese versions).
3. Go to Profile → My Devices → Xiaomi Earphones 2.
4. Find the firmware version string (e.g. 1.7.0.4).

Compare it to the latest available versions in the table below, and if your version is newer or the same as the current version, no update is required.

⚠️ Note: If your headphones are purchased in China but you are using global firmware (or vice versa), the upgrade may result in incompatibility.

Refreshment with Mi Fit or Mi Home

The safest method is to use Xiaomi’s branded apps, which are suitable for Android and iOS smartphones, but there are nuances:

• 📱 On Android, use Mi Fit (version 5.6.0 and higher).
• 🍎 On iPhone – Mi Home (only for Chinese versions of headphones).
• 🔄 Turn off before the upgrade VPN — It can block Xiaomi servers.
• 🔋 The charge of headphones and case should be above 50%.

Step-by-step:

1. Open Mi Fit and connect the headphones to the phone.
2. Go to Profile → Xiaomi Earphones 2 → Update firmware.
3. If a new version is available, click Update.
4. Wait for the file to download (about 5-10 MB) and confirm the installation.
5. Put the headphones in the case and close the lid. Don't open it until the process is complete! The indicator on the case will flash red (load) → blue (set) → green (ready).

Update time: ~10-15 minutes. If the process lasts longer than 20 minutes, see Errors and Solutions.

Update through third-party applications: risks and recommendations

The Play Market and App Store have third-party firmware tools for Xiaomi headphones, such as Earphones Updater or Bluetooth Auto Connect, but they come with risks:

• 🚨 Viruses and spyware – many ‘pirate’ apps collect data.
• 🔧 Incompatibility of firmware - you can install software from another model.

If you still decide to use third-party software, follow the rules:

1. Check the reviews and rating of the application (minimum 4.5 ★ and 1000+ installations).
2. Download only from official stores (Google Play, App Store).
3. Create a backup of your current firmware (if possible).
4. Do not update via mobile Internet – only via Wi-Fi.

1. Put the headphones in the case and connect it to the charger.
2. Hold the button on the case for 20 seconds.
3. If the indicator flashes red, release the button and wait for the reboot.

2. Download a file with the.bin extension for your model.
3. Use the ADB method (see section above), but instead of the installation command, follow: adb shell am start -n com.xiaomi.bluetooth/.activity.DowngradeActivity
4. Confirm the rollback on the phone screen.

⚠️ Note: Recoil is only possible within one firmware branch, for example, from 1.9.2.8 to 1.7.0.4, but not 1.5.0.1 (too old version).
