Many wireless headsets are faced with devices that stop syncing with each other or lose communication with the smartphone. Often the solution is the firmware Xiaomi Airdots, which allows you to eliminate software failures and restore the stable operation of the Bluetooth module. Unlike smartphones, the process looks different here and requires a clear understanding of the algorithm of actions.
Modern models TWS-Headphones, including Mi True Wireless Earbuds Basic, rarely allow the user to directly download update files via a computer. The main mechanism of work is to automatically update through a mobile application or hard reset to factory settings, which is actually "flashing" the configuration of the device. It is important to distinguish these concepts so as not to look for non-existent files.bin for each case.
In this article, we will discuss all the available ways to restore the health of your headphones, learn how to use official tools, how to perform a full reset (Hard Reset) and what to do if the left or right earphone has stopped responding to commands. Careful follow the instructions will help to avoid final failure of the gadget.
Features of firmware architecture TWS-headset
Technically, the microcode update process in the budget and mid-range Xiaomi headphones is centralized. USB-The software is stored in the internal memory of the Bluetooth controller, which controls all the functions of the device.
When it comes to flashing headphones, the most common thing that is meant is to update that microcode via Bluetooth Low Energy (BLE) protocol, to improve connection stability, reduce sound latency, or correct pairing errors. Older versions of firmware often had bugs when the headphones were out of sync, and the new software corrected that logic.
⚠️ Warning: Trying to find and install third-party firmware from unverified sources can permanently incapacitate the controller.
It is believed that each model, whether it is Xiaomi Airdots 2 or Redmi Buds 3 Lite, needs its own unique file. In practice, the ecosystem Xiaomi Mi Home or Xiaomi Wear itself determines the model of the device and offers an up-to-date version of the software that is compatible with the installed hardware. manual intervention is required only in critical situations.
Preparation for the update: necessary tools
Before you start any action with the software, you need to ensure stable conditions. The process of writing data to flash memory is sensitive to power interruptions. If the charge falls during the critical phase, the headphones can turn into a brick.
You’ll need an Android or iOS smartphone with Bluetooth 4.2 or higher installed. Android users often have more functionality, as some system utilities work better with this platform. Make sure that the phone has geolocation enabled, as this is an Android security requirement for scanning. BLE-device.
Charge the case and the headphones themselves to a minimum of 60-80%. Low battery power is the most common reason for unsuccessful upgrades. It is also recommended to clear the list of paired devices in the Bluetooth settings of the phone, deleting old records about your Airdots to avoid addressing conflicts.
- 📱 Smartphone with Android 6.0+ or iOS 12+ installer.
- 🔋 Charged charge case and headphones (minimum 60% charge).
- 📶 Stable Internet connection to download service packs from the server.
- 🧹 Cleared list of Bluetooth devices (delete old profiles).
Official method: Update through the app
The safest and most appropriate way to change the software version is to use ecosystem applications. For different regions and models, these can be different programs. Global versions often run through Xiaomi Wear, while for Chinese versions or a wider range of devices, Mi Home is better suited.
After installing the app, add the device to the list of "My Home" or "My Devices." The app automatically scans the vicinity and if you find compatible gadgets, offers diagnostics. If your Xiaomi Airdots model has an update, next to the device name, a red indicator or an "Update" button will appear.
☑️ Firmware readiness
During the upgrade, don't open the case lid or go far from the phone. The Bluetooth signal should be stable. If the progress bar is frozen by 99%, don't panic - sometimes it takes longer to finalize a record than the main download.

|---|---|---|---|

Hard Reset Method: An Analogue of Flashing
If the official update doesn’t help or the app doesn’t see the device, the only way to “flash through” the logic of the work is a complete reset, which cleans the internal memory of the headphones from all user settings and pairing errors, returning them to a state close to the factory one.
To perform the reset, place both earbuds in the charge case. Make sure they start charging (the indicators light up). There is a physical button on the outside or inside of the case (depending on the Airdots 1 or 2 model) and it needs to be pressed for 15-20 seconds.
The indicator on the case will flash white or orange several times, which signals the beginning of the cleaning process. You need to release the button only after the indication changes the pattern of blinking or goes out, then you need to re-engineer the headphones with the phone as with a new device.
What to do if the button is not pressed?
Solving problems with desynchronization of the left and right channel
A common problem that users try to solve with firmware is desynchronization, when only one earpiece is playing, which is a software glitch where devices lose communication with each other, and 90% of the time, a sequential algorithm of actions that simulates flashing the connection helps.
First, remove the device from the Bluetooth list on your phone ("Forget the device"). Then place the headphones in the case and press the reset button for 30 seconds, ignoring the first flashes of the indicator. Wait until they start flashing quickly and alternately. This is a sign of the pairing mode between the headphones themselves.
⚠️ Warning: During a reset, keep your phone away from the case or turn off Bluetooth on it so it doesn’t intercept the connection ahead of time.
After a successful reset, turn on Bluetooth on your phone and find a new device. The device name can be displayed once, which means successful channel integration. If two names, repeat the procedure again, since the channels have not paired.
- 🔄 Remove the headphone profile from the smartphone's Bluetooth settings.
- 📦 Put the headphones in the case and close the lid for 10 seconds.
- 🔘 Press the reset button before changing the color of the indicator (usually 20-30 sack).
- 📱 Perform pairing again by connecting to only one name in the list.
Recovery after a failed update
If the upgrade fails, the headphones may not behave properly: do not turn on, do not charge or constantly blink. In such cases, the deep discharge cycle helps. Leave the headphones in the case with the lid open for 24-48 hours, so that the battery is completely zero.
Then you put the case on charge for a few hours. Sometimes the power controller only resets the errors after a full discharge and charge cycle. This is not real flashing, but often restores the controller to work.
💡
If the headphones stopped charging after a failure, try cleaning the contacts on the headphones and inside the case with a cotton swab dipped in alcohol. Contact oxidation often simulates a software failure.
In extreme cases, when software methods do not help restore communication between modules, interference with the hardware is required, which implies soldering the chip or using a programmer, which is economically impractical for this category of devices.
