Owners of popular Xiaomi acoustics and Redmi sub-brand often face the need to update software to improve connection stability or eliminate bugs. The process, which is commonly called flashing among enthusiasts, is actually an update of embedded software (Firmware) to the current version. Modern models such as Mi True Wireless Earbuds Basic 2 or AirDots Pro 2, have a closed architecture, which makes classic reflashing through the programmer impossible without opening the case, but the standard upgrade methods are available to everyone.
It should be noted immediately that the term "flashing" in the context of consumer electronics Xiaomi most often implies a regular update via Bluetooth connection. Attempts to find "left" firmware from the Internet to change the region or unlock hidden functions can lead to a complete failure of the device. Official update channels are the only safe way to return the functionality of the gadget or improve its functionality.
In this guide, we will discuss all the legitimate ways to interact with the software of your headphones, how to properly prepare the device, what applications are needed for different models and what to do if the update process is interrupted. Understanding these nuances will help you avoid common mistakes when the headphones turn into a “brick” due to loss of communication during the critical stage of recording data.
Features of the architecture of headphones Xiaomi
The software that controls the wireless headphones is stored on a special memory chip inside the case and samibuds. Unlike smartphones, there is no operating system in the usual sense, but there is a microcode responsible for the operation of the Bluetooth module, audio processing and control of touch panels. The microcode is a low-level program that directly interacts with the hardware of the device.
Xiaomi's device architecture is designed so that each headphone (left and right) has its own independent memory module, but synchronizes through the master device (usually the right earpiece). That's why when upgrading, it's important that both headphones are in the case and have sufficient charge. Interrupting the recording process on one of the modules can lead to desynchronization when the headphones stop "seeing" each other.
⚠️ Warning: Trying to flash headphones with files intended for other models (for example, firmware from Mi AirDots on Redmi Buds) is guaranteed to bring the device down due to incompatibility of hardware identifiers.
Manufacturers use different data protocols to update. Budget models often use a simple binary file transfer protocol through a standard Bluetooth profile, whereas flagship Active Noise Canceling (ANC) models require a more sophisticated handshake protocol to verify the firmware signature. It is critical to understand that interrupting headphones while writing new data to memory leads to irreversible damage to the bootloader.
Preparation for the update: tools and requirements
Before any software manipulation can be done, it is necessary to ensure stable operating conditions. The first and most important requirement is battery power. Headphones and charge case should be charged at least 60-70%. If the battery sits below the critical level during the upgrade, the device can go into deep sleep and stop responding to commands.
The second important aspect is the smartphone, which will act as a firmware source. It is recommended to use devices based on Android or iOS with the latest version of the operating system installed. The Bluetooth module of the phone should work properly, without interference and breaks of the connection. It is advisable to be in close proximity to the Wi-Fi router if the application requires data to be downloaded from the network, although the transmission is over Bluetooth.
☑️ Firmware readiness
Older models such as Mi True Wireless Earbuds Basic are often controlled through the Xiaomi Earbuds app (for Android) or Mi True Wireless (for iOS). Newer and ecosystem devices, including Redmi Buds and Mi AirDots Pro, require the installation of a universal Mi Home app (Mi Home / Xiaomi Home). In some regions, for example in Europe, for full functionality, it may require changing the region in the application settings to China or India.
Instructions: Update via Mi Home app
The most common method of updating is using the official Mi Home app, which is suitable for most modern models integrated into the smart home ecosystem. First, make sure that the headphones are paired with your phone and connected to the Internet. Open the app and find your headphone card in the list of devices.
Go to the device settings, usually three dots in the upper right corner or a long click on the icon. In the menu, find "Update Check" or "Update." If the new version is available, the system will suggest starting to download. The update process can take from 2 to 5 minutes, during which the headphones can emit audible signals or flash indicators.
During the upgrade, the smartphone screen can show the progress bar. Do not switch to other heavy apps or lock the phone screen so that the system does not interrupt the Bluetooth connection in the background. Once the procedure is completed, the headphones will automatically restart and restore the connection.
What to do if the update is suspended?
Redmi and Mi AirDots Firmware via Xiaomi Earbuds
For classic AirDots and early Redmi Buds, the Xiaomi Earbuds app is often used. The interface is simpler, but the functionality is limited. Once the headphones are connected, the app automatically checks the Firmware version. If a new version is detected, a pop-up or Update button will appear on the home screen.
It's important to put both earbuds in the charger case before the procedure, and the app will update the right headphone, then the left earbud, or both at the same time, depending on the model, at which time the indicators on the case may flash white or orange, which is a standard behavior that indicates data recording.
- 🔹 Make sure the case cover is open during the entire process.
- 🔹 Keep your smartphone at a distance of no more. 10-15 case-case.
- 🔹 Do not press any buttons on the case while the indicators blink.
If the headphones are no longer paired after the upgrade (only one works), a reset procedure will be required, which usually involves holding the button on the case for 10-15 seconds until the indicator flashes white quickly, and then re-pairing the phone's Bluetooth menu.
💡
Tip: Before updating, take a picture of the current equalizer and touch control settings, as after firmware they can be reset to factory values.
Problem Solving: Headphones don't see the update
A common situation is when the app says "Version is relevant" even though forums are already discussing a new release. This may be due to regional restrictions of Xiaomi servers. The server in your region may receive updates later than the server in China. In such cases, experienced users change the region in the Mi Home app settings to "China", but this can lead to the appearance of Chinese in the headphone management interface.
Another reason is the app cache. Accumulated temporary files can block the receipt of up-to-date information about software versions. You need to go to the smartphone settings, find the Mi Home or Xiaomi Earbuds application in the list of installed programs and select the "Clear Cache" option (not data, namely cache), after which you need to completely reboot the smartphone.
| Symptoms. | Possible cause | Decision |
|---|---|---|
| Update button is inactive | Low battery charge | Charge the case and headphones up to 80% |
| Connection error at 50% | Bluetooth interference | Get closer to the phone and turn off others. BT-device |
| Endless test | Server problems | Change Wi-Fi network or use mobile Internet |
| Headphones not visible in the app | The wrong region | Check the region in the Mi Home settings |
It is also worth checking the application's access rights. To properly operate the Bluetooth scanner and update the firmware, the application requires geolocation permissions (in Android this is necessary for Bluetooth Low Energy to work) and access to the local network. Without these permissions, the process can be interrupted at the initial stage.
Resetting and Recovery: What to Do When
If something went wrong during the firmware process and the headphones stopped responding, don't panic. In most cases, a full reset helps. For models without a physical button on the case (for example, AirDots Basic), touch reset is used: you need to take the headphones out of the case and simultaneously touch the touch areas on both headphones and hold for about 20 seconds until they turn off, then put them in the case and repeat the procedure.
⚠️ Warning: If the headphones are constantly on or flashing red/orange without interruption after a failed firmware, this may indicate damage to the bootloader.In this case, self-repair is impossible, a memory chip in the service center is required to be replaced.
For models with a button (e.g. Mi AirDots Pro, Redmi Buds 3 Pro), the algorithm is simpler. Place the headphones in the case, open the lid, and hold the function button on the back or inside of the case for 10-15 seconds. The indicator should flash white several times, signaling a reset (conjugation).
In the rare cases where software resets don't work, deep discharge is used. Leave the headphones in the case with the lid open until the charge is completely depleted (for a few days). Then put the case on charge. Sometimes after a full discharge-charge cycle, the power controller resets the errors and allows you to re-enter the refresh mode.
💡
The main rule of successful firmware is connection stability and full charge. Don't interrupt the process, even if it seems to be stalled.
