se enchufa y se mantiene apretado reset hasta que llegue a .. FALSE (dos seguidos, como dos estados de arranque). Ahí se suelta reset (sino no sigue) y llega a un shell en el que no se puede escribir, ahi reiniciamos el putty y ya podemos escribir.
no hay odm, ni wget. Tiene un servidor http y un servidor de telnet. tambien tiene un cliente de telnet y un tftp. no tiene la particion mtpblock2, y tanto la 0 como la 1 se reconocen pero no se montan. ademas, da errores de crc al intentar leer la particion mtpblock0 (meraki)
no tiene /storage
puede coger ip y comunicarse por ping y tftp.
