1.09, 6.01, 6.03, 7.05 16K -32K tried with firmwares .. I got the same error...
I bought the modem used... there is a modem in the original software.
I did not install any other firmware to this modem.
Now I'm trying to install the firmware for the first time ...
The only problem is, when I load script does not sb6120 new window.
I have tried on three different computers.,
I've tried different versions of the program blackcat usb.
But always got the same error.
This error is caused by that software? operation or on the connections or devices? ...
New learning. Waiting for your help, thnks
