Crazyflie m2 led light remains solid blue while working on crazyswarm #670

Hi, I was working on Crazyswarm. It worked for a few runs then this problem occurred. When I turn on my crazyflie only M2 lights up solid. If I try to put it on bootloader mode, only m2 blinks. Only the M2 Led is fully lit (Blue) when I plug the USB cable. With battery plug-in, same result: only M2 blue Led fully lit. I can't charge the battery. I have several batteries (crazyFlie2 batteries) and tested with different ones: the same result. I also tested several USB cables, without success. Board is clean. No big crash or shock on the board... VCC measured is ~3V. Also, I have started the board in bootloader mode by holding the power button and starting it for 3 seconds until the M2 led starts to blink to check if M3 led starts to blink then. No luck...

The VCC is at 2.99V so that's not the problem. I tried using the cfclient to reset the bootloader using the instructions (replug radio, etc) and nothing happens. I have changed out the batteries and left the crazyflie unplugged for a few minutes. I tried powering it just over USB and there is no change. I tried using the cfloader flash tool but it says it can not connect to the bootloader. I also tried cold bootloader mode with USB as well as Batteries.
