So I guess I finally broke this thing. I've gotten pretty decent at flying and have been zipping it allover the house. Well it worked fine last time i used it, went to fly again and this time when I power on the crazyflie it will not spin the motors and do a self test. Instead the 3 LED's stay lit solid. Sometimes only the blue LED comes on, but usually all 3. I can't connect in boot-loader either. When I plug in usb, the motors will spin for a second and it seems to self test. I'm at a loss now, and don't know where to proceed. Any ideas?

Thanks,
Nick

Does it work when you plug in the usb? Didn't really follow you?

I would guess that some solder got a crack which can be hard to locate/find but I suggest you give it a try. And it is more likely to happen for the bigger components so start with the MCU on the bottom side. You could press on the MCU and power it on to maybe see if it works then which would indicate a cracked solder.
