hello

I'm following this tuto : http://eevee.cc/2017/05/10/headless-firefly-rk3399-setup/

and i'm blocked at the step 4.4
at the step 3.5 a got a different name than rockusb device.
my computeur (inder win 10) don't see as rockusb Device but as firefly-rk3399

I try to unintall/reinstall but I got the same result after a lot of try, it's still sthe same.

at the step 4.4 I can find the firmware but i can't upgrate it and I got a message error "match device type fail,stop running!"

I try to change the name of the path to match the name of the device on my computeur but it change nothing.

Is there somebody that got an idee how to fix that or juste another method ?

i got a firefly RK3399 by the way
