Lost Boards after update firmware VS-GWM400

Good Afternoon!

I solved by following the procedure below.

thank you, I will try that

Hi,
In the picture i can't see which wire is cut - GND or 3V3

Good night!

the cut wire is 3v because the board will be fed by the chassis.

Consegui el cable usb to ttl, me conecto al board mediante el putty, veo el booteo del equipo.... pero las entradas del teclado, ya sean letras o la tecla enter, funcionan, pero no les hace caso, el equipo continua booteando como si no estuviese tecleando nada.

I got the cable usb to ttl, I connect to the board through the putty, I see inthe terminal the boot of the unit.... but my keyboard entries, either letters or the enter key, work, but the board ignores them, the gateway continues to boot as if I was not typing anything.

Good afternoon!

try to give a new reset on the board, I had problem but as the serial cable / usb in windows 10 I circumvented using windows 7 to do the procedure.
