Owners of the popular Xiaomi M365 and its modifications, such as the Pro or Pro 2 (often referred to as the S1 in some regions), often face software restrictions, which can be related to the region of sale, which prevents the device from connecting to the application or using all the functions of the controller. Unlocking the scooter is a process that allows you to access full control of the gadget and allow you to use it outside the importing country.
The procedure for removing locks requires careful attention, as it is working with low-level controller software. Incorrect actions can cause the scooter to stop responding to commands or stop turning on altogether. In this article, we will discuss in detail the safe methods for changing regional settings and removing software speed limits.
Reasons for blocking and types of software restrictions
Manufacturers often install software locks to comply with the laws of different countries, for example, in the European Union there are strict rules regarding the maximum speed of electric vehicles, while in other regions these rules are milder, blocking usually affects the firmware of the controller and the Bluetooth module that checks the region of the smartphone connection.
There are several layers of protection. The first level is the inability to pair with the Mi Home or Xiaomi Home app if the region in the account settings does not match the region of the device. The second level is an artificial speed limit that does not allow you to develop more than 25 km / h, even if the hardware allows it. The third level is the lockdown of the launch when the charge is low or BMS errors, which can only be fixed by flashing.
⚠️ Note: Removing software restrictions may result in the loss of the official warranty.
Unlocking is often required after purchasing a device on Chinese marketplaces for use in Europe or the CIS, in which case the scooter can be blocked to work only with Chinese servers. This is done through special utilities that transmit commands directly to the BMS (Battery Management System).
Tools required and preparation for the procedure
Before you start unlocking, you need to prepare the workplace and software. You will need an Android smartphone, as most tools for working with BMS are designed for this platform. iOS has stricter security restrictions, which makes the process more difficult and less stable.
To start, make sure your scooter has a battery charge of at least 30-40%. Interrupting the process of writing data to the controller's memory due to discharge can lead to irreversible consequences. Also check that the Bluetooth on the phone is on and working correctly.
☑️ Preparation for unlocking
You will need a special patcher application. The most common and proven tool is Xiaomi Flasher or its modifications, such as M365 DownG or BleUnlocker. These applications allow you to read the current version of the firmware and replace it with a modified one, or simply change the regional flag.
⚠️ Note: Do not use unverified applications APK-files found in random chat rooms, which may contain viruses or incorrect firmware code.
Step-by-step instructions for changing the region and removing locks
The unlocking process begins by connecting the patcher app to the scooter. Run the downloaded utility on your smartphone and press the device search button. Make sure the scooter is on but not in riding mode. When the app detects your Xiaomi M365 or Pro 2, click on the model name to connect.
After successful pairing, you will see the current firmware version and the BMS version. At this point, it is important to back up your current settings if the application provides such a feature. Then select the option "Patch Firmware" or "Change Region." You will be prompted to select a target region, for example, "Global" or "Europe".
What to do if the connection is interrupted?
Once you select a region, you start recording. You'll see a progress bar on the screen. You can't turn off the scooter or shut down the app at that point. You can interrupt the recording and you can block the controller. You can wait for the successful completion of the operation.

Do not turn off power!When the process is complete, the app will report success. Turn off the scooter with the power button and turn it on again. Now try connecting through the official Xiaomi Home app, selecting the appropriate region in your account settings. If everything goes well, the speed limit will be removed and the region changed.
💡
After successful flashing, it is recommended to completely discharge the battery before the scooter is turned off, and then charge it to 100%, which will help the controller calibrate the data on the capacity of the cells.
Removing BMS errors and resetting the mileage counter
Often, unlocking is required not only to change the region, but also to correct errors that block engine start. Errors can occur due to desynchronization of data between the controller and the BMS. For example, after replacing the battery or controller, the scooter may refuse to drive, giving a flashing red indicator.
With specialized applications, you can perform error reset and calibration. From the patcher menu, select "Tools" or "BMS Tools." This includes error counter reset and cell voltage calibration, especially for the Xiaomi S1 models that were used in harsh environments.
The table below shows the error codes and methods for eliminating them through a software reset:
| Error code | Description of the problem | Elimination method |
|---|---|---|
| 31 | Communication error with the controller | BMS flashing, plume checking |
| 34 | Low cell voltage | Balancing, BMS reset |
| 38 | Controller overheating | Cooling, resetting sensor errors |
| 40 | Mistake. MOSFET | Replacement of the controller or firmware patch |
It's important to understand that software resets don't fix physical damage. If the battery cell is really dead or the controller is burned, flashing it won't help. However, if the problem is caused by a software failure, this is the most effective way to bring the machine back to life without going to the service.
Configuring speed and recovery parameters
Once you unlock successfully, you get new customization options. Standard firmware often limits recovery current and maximum speed. Modified firmware allows you to increase these parameters, making driving more dynamic.
Patcher apps often have a "Settings" or "Tuning" section, where you can change the speed limit from the standard 25 km/h to 30-32 km/h, which is the physical limit for Xiaomi engines, and you can also adjust the accelerator sensitivity and recovery force.
Increased recovery current allows the battery to be more efficiently charged on descents, but can cause the controller to overheat when used frequently.
💡
The optimal setting for the city is 28-30 km/h and medium recovery, which provides a balance between dynamics and temperature of the controller.
Possible risks and security measures
Despite the simplicity of the process, there are risks: the main danger is the use of incompatible firmware. For each model (M365, Pro, Pro 2, Essential) there are different versions of the BMS. Trying to flash the Pro 2 controller with firmware from a regular M365 can cause the device to fail.
Always check your device model before starting the procedure. The model is usually listed on a sticker under the deck or on the app before locking. If you are not sure about yourself, it is better to contact a specialist. Repairing a burned controller will cost much more than the cost of unlocking.
⚠️ Warning: Once unlocked, the protection system may be less aggressive. Watch the temperature of the deck and controller during the first trips.
