Can be supported by manually replacing the recovery firmware file (e.g., DRV247 for Pro 2 or DRV319 for 1S) within the tool directory.
The package is a specialized recovery toolset used to unbrick and restore Xiaomi Mi3 e-scooters (and similar models like the Pro 2 and 1S) that utilize the GD32 microcontroller (MCU). Released by the developer Conejo within the scooter tuning community, it serves as a critical fix for "bricked" controllers—specifically the V3.1 controller —which often occurs when users attempt to downgrade firmware via Bluetooth on newer models. Core Functionality
The package includes a batch script named "runme_mi3_reflash.bat" which automates the flashing process, requiring minimal user intervention once the hardware is connected. Compatibility & Variants While originally developed for the Xiaomi Mi3 gd32rec_by_conejo.7z
The tool is primarily designed to reflash the controller's firmware when standard wireless methods (Bluetooth/Smartphone apps) no longer work.

In some cases, users must hex-edit the full_mi3_gd32.hex file to insert their specific scooter's serial number to ensure correct identification by apps after flashing.
It supports both GD32E (Type 1) and GD32F (Type 2) microcontrollers found in newer Xiaomi ESCs. Type 1 usually requires this tool via ST-Link to recover, whereas Type 2 might sometimes still allow Bluetooth flashing. Usage Overview Core Functionality The package includes a batch script
