Reach image 2.3 flashing problem

I downloaded the newest image file
I started the flashing, it was finished and here is the flash.log:
flash.log (6.3 KB)

When I connect to the Reach’s hotspot I can set a new wi-fi network. But after that the Reach doesn’t connect to the new network.

I wanted to reflash again the Edison, but the Board configuration tool says that de device is undetectable. So flashing doesn’t work.

I also tried to reflash on two different windows pc’s and a linux pc.
What could be the problem and this method could help or not?

Thanks a lot!

Does that mean you were successful?
