Xiaomi Mi True Wireless headphones (including Basic 2, SE, TWS 2 and others) regularly receive firmware updates that improve sound, connection stability and battery life. However, many users face difficulties when trying to update the software β the headphones are not defined in the application, the process is frozen, or the new version simply does not install. In this article, we will discuss all official and alternative ways to update, and also explain how to avoid typical errors.
It's important to understand that the firmware for Mi True Wireless is distributed through the Mi Home app (now Mi Fitness for some regions), but there are hidden methods for forced installation. If your headphones started to glitch after the upgrade or stopped turning on at all, do not panic: in 90% of cases, the problem can be solved without going to the service center. Next, you will find step-by-step instructions for each model, a firmware compatibility table and answers to frequent questions.
1. How to check the current firmware version
Before you update your headphones, make sure the new firmware version is actually available.
- Connect the headphones to the smartphone via Bluetooth.
- Open the Mi Home app (or Mi Fitness if you have international firmware).
- Go to the Profile section β My devices and choose your headphones.
- Click on the three dots in the top right corner and select Device Information.
In the window that opens, you will see the firmware version line (for example, V4.7.1_20231012). The last two groups of digits indicate the date of release of the firmware (year/month/day). 6 months - it is recommended to update.
If the app doesnβt show a firmware version, try an alternative way:
- π± For Android: use the nRF Connect app (available on Google Play). Connect your headphones and in the Device Information section, find the Firmware Revision field.
- π For iOS: In Bluetooth settings, click on the i icon next to the headphone name β sometimes the version appears there.
2.Official method: Update via Mi Home
The safest method is to use a proprietary app. Here's how to do it:
Make sure your headphones are at least 50% charged | Connect them to your smartphone via Bluetooth |Close all background apps except Mi Home |Plug your phone to stable Wi-Fi
-->
- Open Mi Home and go to the Profile β My Devices tab.

During the update, do not turn off Bluetooth or remove the headphones from the case (if they are in it). If the process is suspended during the Prepare for Update stage for more than 10 minutes, restart the headphones (press the button on the case for 10 seconds) and try again.
β οΈ Warning: If your headphones are connected to multiple devices (like your phone and laptop), disconnect them from all gadgets except the one from which the update is being performed.
Once the upgrade is successful, the headphones will automatically restart. To make sure everything goes right, check the firmware version again according to the instructions in the first section.
3. Alternative ways of updating
If the official method doesnβt work (for example, the app doesnβt see the headphones or doesnβt offer an update), you can try the following options:

- If the message βNo Updateβ appears, repeat the check after 1-2 hours β sometimes Xiaomi servers give false negative results.
Method 2: Update via computer (for advanced users)
This method is suitable if the headphones are not defined at all in the Mi Home.
- π» Windows computer 10/11
- π USB-Case connection cable (not all models support this!)
