To upgrade the Crazyflie 2.0 firmware: Press the ON/OFF switch more than 1.5 second until the blue led blinks. Then release the button and the two blue leds should blink.
I have four Crazyflies 2.0. In three, the procedure was successful, however, in one of them there was an error. Only the M2 led blink, while the M3 stays on but not blinking.
The program reports: Could not connect to bootloader
How to proceed in this case?

You probably hit a failed flashing. Then start from a cold boot which means remove power (battery and usb), hold button while connecting either of the power and you should be able to get into bootloader mode.
