It appears that nb0 are the same as nbf but with no header. From what I read nbf are encoded and have to be unencoded to a nb0 and then back to an nbf. Here is some info:

Why don't you try and see the contents of the files using one of the xda tools like dumprom? See if it can read the contents.

I will sign up for a free webhost today and give you the address. Could you pleae upload the files to it?

Thanks.
