A. run led blinks briefly is USB dirver is not intalled correctly.  Reinstall software.
B. Ver0.0.0 is bootloader, none  of test function.you need to refrash firmware first.


It is usually caused by using a USB hub.

1.do not use an external HUB when refreshing.

2.directly connect the programmer to the USB port of your computer's mainborad to refresh.
3. Restart the computer to test. If it still cannot solve the problem. try to do the refresh operation on another computer.
