Hello everyone ,
I finished Installing the firmware with success .
But thie issue I have now is connecting it could any one give some advice how to step up , thank you in advance 
Determine the com port it’s on in Windows device manager. Select that port from the pull down menu, 115k baud and connect.

FWIW,
sometimes I have a lot of com ports. Using ‘auto’ and 9600 will connect using a very slow baud rate but to the correct com port.
Once that’s done it’s easy to disconnect and re-connect with the same com port and 115200 baud.
