I think it maybe has write lock with bios.
You need solve this problem at first ,or you can try to use other tool to dump current bios ,don't use offical flash utility.
It was. It is an older one, so we sorted it out and I got it from there.
How can I unlock the bios? Is there a way?
We had an external contractor for notebooks and they modified it. But the guy who has done it do not work for them anymore.
