The Xiaomi Mi Electric Scooter Pro series (M365 Pro, Pro 2) has proven to be reliable vehicles, but its standard software often limits the device’s real potential. Owners face artificial speed limits, regional feature locks, and a not always optimal recovery algorithm.
The process of updating or replacing firmware requires care and understanding of the risks. Mistakes can lead to locking the controller or battery, which will require expensive repairs in the service center. However, with all technical requirements and using proven tools, the user gets full control of his device, opening up hidden control options.
In this guide, we will cover all aspects of working with scooter software, from standard updates to complex manipulation of regional settings and custom versions. You will learn what tools you need, how to prepare for the procedure and what to do in case of errors. It is critical to understand that changing the firmware region to Chinese or American can lead to irreversible changes in the BMS algorithms (Battery Management System).
Why Change Standard Firmware and What Risks Are There
The main reason why enthusiasts are choosing to reflash the Xiaomi 365 Pro is due to regional restrictions: the European version of the software often limits the top speed to 25 km / h, while the American or Chinese versions can allow you to accelerate faster. In addition, custom firmware such as Draco or Custom Firmware offer advanced recovery settings, the ability to turn off autolock wheels and detailed monitoring of battery cells.
However, there are risks to the code, and the biggest problem is the potential battery lock, and if the data record fails or incorrect information is recorded in the BMS memory cells, the battery can go into a protective mode from which only specialized equipment can remove it, and there is a risk of the controller being “bricked” if the upgrade process is interrupted.
Legal aspects are also important: the use of modified software that removes speed limits may be contrary to the traffic rules of your country, it becomes illegal to operate such a vehicle on public roads, and in the event of an accident, serious problems with the insurance company can arise.
⚠️ Warning: Any firmware manipulation removes the device from warranty service. If the scooter is warranty, any software changes will be considered by the service center as a violation of operating conditions.
However, for many users, the benefits outweigh the risks: the ability to fine-tune the throttle response, calibrate the brake system, and obtain complete battery health statistics make the process popular among technologists.
Necessary tools and preparation for firmware
Before you start the action, you need to prepare the workspace and software. You will need a computer running Windows (preferably version 10 or 11), as most of the scooters utilities Xiaomi is written for this platform, and you will need a stable Internet connection to download the firmware files.
The official method requires the use of the original charger and Xiaomi Home or Mi Home app, but deep flashing often requires a physical connection via a remote link. UART or the use of specialized BLE-The scooter is perfect for working with the Bluetooth protocol. USB-chip-adapter CSR 4.0 or newer.
- 🔌 USB Bluetooth adapter (minimum version 4.0) for wireless communication with the controller.
- 💻 PC or laptop with Windows operating system.
- 🔋 Charger with a charge level of the scooter battery at least 60%.
- 📱 Smartphone with installed application for initial diagnosis.
It is important to check the version of the current software. You can do this through the application or by looking at the error code on the display when you turn on. Write down the current settings so that if you fail, you have a point of return. Make sure that the Bluetooth drivers on the computer are installed correctly and the device is visible on the system.
Download the necessary firmware files in advance. Do not rely on downloading during the installation process, as a connection break can fatalize the process. Firmware files usually have the.bin or.zip extension and must be placed in the root folder or special directory specified in the instructions for the utility used.
Standard Update Process through Official Annex
The safest way to update software is to use regular tools, a method that is suitable for those who want to simply fix bugs or get official improvements without risking system stability, the process begins with connecting the scooter to a smartphone via Bluetooth.
Launch the Mi Home app and select your scooter from the list of devices. If an update is available, a notification will appear next to the device icon or in the settings menu, the system will check the version compatibility itself and prompt you to download the data packet.
☑️ Preparations for renewal
When you start downloading, don't switch to other apps or lock your smartphone screen. The Bluetooth signal should be stable. During the data transfer, the scooter can make sounds or flash indicators - this is the normal response of the controller to incoming data packets.
When the file is uploaded, the installation process will begin, at which time the scooter can turn off and then turn on again, error codes or flashing symbols may appear on the screen, interruption of the process at this stage is strictly prohibited, as this can damage the bootloader.
⚠️ Warning: Do not pull the trigger or spin the wheel during the update. Any interaction with the controls may be considered an emergency by the controller, which will interrupt the firmware process.
When the installation is complete, the scooter will automatically restart. Check the software version in the application to make sure the operation is successful. If the version has not changed or there is an error, repeat the procedure, after completely discharging and charging the battery.
Change of region and unlock speed (Advanced)
For more advanced users, a change in the region of the firmware is of interest, which allows, for example, on a European scooter to activate functions available in the US or China, or vice versa, often to increase the maximum speed or change the algorithm of regenerative braking.
To do this, standard applications are not enough. You will need specialized software such as Xiaomi Flasher or utilities from the development community working through BLE (Bluetooth Low Energy), which allows you to send raw commands to the controller without checking regional compatibility.
| Region | Max. Speed (officially) | Features of BMS | Risks. |
|---|---|---|---|
| Europe (EU) | 25 km/h | Strict control | Low. |
| United States (US) | 30 km/h | Less strict. | Average. |
| China (CN) | 25-30 km/h | Specific | High (language, frequencies) |
| Global (Global) | Depends on the zone. | Universal. | Average. |
The process of changing the region looks like a regular firmware flash, but with the choice of a firmware file from another region. It is critical that the hardware version (Hardware Version) matches. Trying to pour firmware from Pro 2 on a regular M365 or vice versa will lead to the inoperability of the controller.
What if the scooter does not turn on after the region change?
After the region changes, the gyroscope and accelerometer may need to be calibrated, and this is done by placing the scooter on a flat surface and performing a sequence of actions through the diagnostic menu, and without calibration, the stabilization system may not work properly.
Some users have noted that the logic of the battery charge indicator changes as the region changes, due to different lithium cell discharge profiles sewn into software for different markets, and be prepared for the fact that the percentage of charge may become less accurate.
Installation of custom firmware and advanced setting
Custom Firmware is a modified version of software created by independent developers that gives access to hidden parameters that are not available in the sewage software, for example, you can change the recovery force, adjust the reaction to the trigger of the gas or activate the "no key" mode.
One of the most popular custom firmware is Draco, which allows you to customize almost all aspects of the scooter in detail through a convenient menu on the display or through the application, and installing such firmware usually requires the use of a special loader.
The installation process often goes like this: first, a special “intermediate” firmware is put in, which opens access to system files, then the main custom firmware file is downloaded through a file manager or a specialized utility.
- 🚀 Advanced recovery settings (you can make braking more smooth or sharp).
- 🔓 Disabling regional speed limits (at your own risk).
- 📊 Detailed diagnostics of battery cells in real time.
- 🎨 Changes in display interface and brightness of indicators.
It is important to understand that custom firmware has no official support. If an error occurs after installation, the firmware developer is not responsible for the damaged device. Always back up the original firmware before installing mods.
💡
Before installing custom firmware, take a picture of all the current settings and battery settings, which will help you get back to the way it was if you don’t like the new version of the software or it will work unstable.
Some custom firmware features may conflict with hardware, such as setting up too aggressive current settings, which can overheat the controller, and monitoring the temperature of the nodes on the first trips after flashing.
Diagnostics of errors and recovery after failure
If something goes wrong during the flashing process, the scooter may stop responding to commands or issue error codes. The most common problem is that the scooter turns on but doesn't go, or the red indicator burns. The error code can usually be seen by quickly pressing the switch several times.
To restore performance, a "hard reset" or UART flashing method is often used, requiring the scooter deck to be opened and the controller's contacts connected via a USB-TTL adapter, a method for advanced users familiar with electronics.
If the scooter just “hangs” after the upgrade, try to turn off the battery for 10-15 minutes, this will allow you to reset the residual charge from the controller capacitors and BMS. Once the battery is reconnected, the system can start correctly.
In the event of a BMS error (e.g. flashing red 8 times), the cell balancing table was most likely damaged, and recovery is possible only through connection to the service battery connector and the use of special software for BMS calibration, which is best trusted by professionals.
⚠️ Warning: If the scooter makes a loud squeak or smoke after flashing, immediately turn off the battery! This is a sign of a short circuit or a critical controller error, further operation is dangerous.
To diagnose battery status after flashing, use applications like Xiaomi Scooter Hacking Utility, which will show real capacity, number of charging cycles and imbalance of cells, and the sudden change in these indicators after firmware is a worrying sign.
