Hello,

How did you proceed? Did you pull the BOOT0 pin to VDD then reset the MCU before to connect?

By default SB18 is soldered pulling down Boot pin to the ground which don't allow you to enter the system bootloader.

You need to unsolder SB18 and and handle BOOT0 externally from the board's pin VDD (system bootloader) and GND (User application).
