On uConsole keyboard back,there is a **UART** port which can be used with `stm32flash` to flash keyboard stock firmware  

Especially when your keyboard met problem  

here is the process:  

* put the switch 1 ON
* connect uart with a **fpc 6p connector 0.5mm** to a serial-usb converter
* use stm32flash to flash bin file
* put the switch 1 OFF
