How to Sweat a Xiaomi Scooter M365 Pro: Complete guide to photos and videos

Xiaomi firmware M365 Pro is a process that can radically change the behavior of a scooter, from unlocking the speed limit to fixing the original software bugs. However, the wrong actions lead to the "bricking" of the device, loss of warranty or even danger while driving. In this article, we will analyze all the stages of firmware: from the choice of the software version to recovery after failures, taking into account the features of the Pro model (different from the basic one). M365 more powerful motor and battery).

It is important to understand: firmware through informal tools like DownG or M365 Tools voids Xiaomi's warranty. Official updates through Mi Home are safe but limit functionality. We'll show both options, and we'll also show you how to avoid common mistakes - such as why a scooter might not turn on after a firmware, or show an Error 21 error. If you are a beginner, start by reading the section on risks and preparation.

Preparation for firmware: what you need to know before you start

Before you start, check out three key points:

• 🔋 Battery charge: at least 60%, and the firmware can be interrupted at low charge, causing damage to the controller.
• 📱 Smartphone compatibility: DownG needs Android 7.0+ supportive OTG. iPhone is not suitable.
• 🔧 Backup: Save your current scooter settings (e.g., via Mi Home) if you plan to return to them.

Pay attention to the controller version (ESC) yours M365 Pro. You can find it in the Mi Home in the About Scooter section or through DownG (Read Version button). The Pro has controllers 1.5.4, 1.6.1 and later. M365 This is not suitable for Pro, and will result in an Error 14 error or complete inoperability.

⚠️ Note: If your scooter is purchased after 2022, there is a high probability that it has a locked controller with third-party firmware protection. Check this through DownG - if the version appears Read Failed error, firmware without soldering is impossible.

Also prepare:

• 🔌 Cable OTG (scooter).
• 💻 Laptop (if you use it) STM32 CubeProgrammer for Recovery).
• 📄 Firmware file (official or custom - see the next section).

Selection of firmware: official vs custom

There are two types of firmware for Xiaomi M365 Pro:

For custom firmware versions are popular:

• 🚀 ScooterHacking Utility (SHU) — Flexible settings, support M365 Pro.
• ⚡ DownG Mod – Simple installation, unlock speed.
• 🔧 Custom Firmware (CFW) — for experienced users (configuration) PID-controller).

If the goal is simply to remove the speed limit, DownG is fine. To fine-tune (for example, changing the brake stiffness or recuperation force) you need to CFW. Choose the official firmware if the scooter is glitching or you need to return the warranty state.

💡

Before installing custom firmware, check that it is compatible with your version of the controller. For example, firmware for 1.5.4 will not work for 1.6.1, which will lead to an Error 15 error.

Step-by-step: Firmware through DownG

This method is suitable for installing custom firmware without soldering.

• Android smartphone with root rights (not necessarily, but recommended).
• DownG app (version 3.1)+).
• Firmware file (e.g, M365Pro_30kmh.bin).

Steps:

1. Connect the scooter to the phone through OTG-cable).
2. Launch DownG and press Connect. If the connection is not established, try restarting the scooter (hold the power button for 10 seconds).
3. From the menu, select Flash Firmware and download the firmware file.
4. Press Start and wait until it is completed (3-5 Don't turn off the cable!
5. After restarting the scooter, check the software version in DownG (Read Version button).

If the scooter does not turn on after firmware or shows Error 21, try:

• 🔄 Re-flash (sometimes it helps to re-install the same version).
• 🔌 Connect to charging for 30 minutes – sometimes the controller “hangs” after the update.
• 🛠️ Use it. STM32 CubeProgrammer for recovery (requires disassembly of the scooter).

⚠️ Note: Firmware via DownG on some versions M365 Pro (e.g., with a controller 1.7.0) can lead to a permanent Error 14 error, in which case only soldering of the chip or replacing the board will help.

Firmware through Mi Home: the official way

If you don’t want to risk the guarantee, use the official Mi Home app, which is safe but limits the functionality of the scooter.

Instructions:

1. Install Mi Home from Google Play or App Store.
2. Connect the scooter to the application (via Bluetooth).
3. Go to the scooter section. → Settings → Firmware update.
4. If a new version is available, click Update and wait until it is completed.

Official updates usually fix bugs but don't add new features, such as version 1.5.8 for the first time. M365 Pro corrected error with sudden motor shutdown, but speed limit remained.

💡

Official firmware via Mi Home is the only way to keep Xiaomi’s warranty.All other methods are considered hacking and void warranty obligations.

If the update via Mi Home does not start:

• 📶 Check your internet connection (update downloaded from Xiaomi servers).
• 🔄 Reboot the scooter and phone.
• 📱 Update the Mi Home app to the latest version.

Speed unlock and other tweaks

The main reason for Xiaomi firmware M365 Pro - Removal of the speed limit in 25 Km/h Castom firmware allows you to disperse the scooter to 30-35 mileage per hour, but it has consequences:

• ⚠️ Increased wear of the engine - with prolonged driving at high speed, overheating is possible.
• 🔋 Fast battery discharge – autonomy is reduced by 20-30%.
• 🚨 Loss of warranty – Xiaomi does not repair scooters with unofficial software.

In addition to speed, custom firmware allows:

• 🔄 Set up the regenerative braking force (KERS).
• 🎛️ Change the sensitivity of the gas (for smooth acceleration).
• 🔇 Turn off the audible signals (for example, squeaking when turned on).
• 💡 Activate the backlight (if installed) LED-ribbon).

To adjust the parameters after the firmware use:

• DownG - basic settings (speed, KERS).
• M365 Tools - Extended parameters (PID-controller, current restriction).
• ScooterHacking Utility – for experienced users (configuration via console).

Errors after firmware and their correction

If after firmware scooter behaves incorrectly, use this table:

To restore the "brick" scooter:

1. Disassemble the scooter and find the controller board (under the deck).
2. Connect. STM32 contact-programmer SWD (We need a soldering station).
3. Launch it. STM32 CubeProgrammer and run the original DRV-file.
4. Get a scooter and check the performance.

⚠️ Attention: If you are not sure about your soldering skills, you should contact the service. Incorrect connection of the programmer can permanently disable the controller.

Update BMS and battery firmware

In addition to the main firmware, in Xiaomi M365 Pro has a separate software for BMS (Battery management systems: It is rarely required to be updated, but can solve problems with battery management:

• 🔋 Incorrect display of the charge level.
• 🛑 Suddenly shutting down the scooter.
• 🔥 Battery overheating.

For firmware BMS:

1. Download the file. BMS (for example, M365Pro_BMS_v2.1.5.bin) proven-source.
2. Connect the scooter to DownG and select Flash BMS.
3. Download the file and wait until it is completed (the process takes time). ~10 minutes).

Important: Don't interrupt the firmware BMS — If the process is stalled, disconnect the scooter from the network and try again in 30 minutes.
