Sounds like you need to re-flash your Crazyflie using the bootloader. If everything is blocked, the way to re-launch the bootloader is:
1) Disconnect the battery
2) Press the power button
3) Connect the battery while the button is pressed
4) As soon as the M2 Blue LED starts blinking, release the button

Now both blue LEDs should blink and if so you will be able to flash the Crazyflie using the Crazyflie client.
