4. Press Start Flash and wait until it is completed (the process will take place). 3-7 minute).

After firmware is installed, the scooter will automatically restart. Check the new settings in the DownG menu (such as top speed, recovery level or brake sensitivity). Note that some custom firmware disables overheating protection, which can shorten the life of the engine.

4. Firmware through STM32 CubeProgrammer: for experienced users

If you want full control over the firmware (for example, to install OpenSource firmware or debug the controller), you will need to work with the software. STM32 CubeProgrammer, which requires soldering skills and an understanding of electronics, because you have to connect directly to the controller board.

Equipment required:

• 🔧 soldering iron with a thin sting and solder.
• 🖥️ ST-Link V2 or other compatible programmer.
• 💻 PC fitted STM32 CubeProgrammer (download from STMicroelectronics).
• 📁 Firmware in.hex or.bin format (for example, ESC-firmware for 365 Pro).

Step-by-step:

1. Remove the bottom cover of the scooter and find the controller board (usually located under the platform).
2. Seal wires from ST-Link to contacts SWD on the board (see diagram for STM32F103).
3. Connect ST-Link to the PC and launch STM32 CubeProgrammer.
4. Select the firmware file and click Start Programming.
