Desbloquear canales en atheros ar9485 mini pci

Alguien conoce algun tutorial o guia que funcione para modificar la "eemprom" de esta, para que pueda desbloquear los canales que están capados por código regional?

He probado "athero eeempro tooll" pero me sale el siguiente error al tratar de sacar eemprom: device i/o error internal error
