Over the last couple of weeks most of the cards i'm popping (rom11's or 10's) are saying they are unlocked but when I come to read in nagra its not letting me past backdoor 0?? I've re tried them with different scripts and still the same? Trust me i've searched for an answer using mrom, xncs and romstudio but struggling on this one? Its no great big deal cos I can get the keys using the other methods but this one's doing my head in now?? Any suggestions??
