Creating a backup .FBN system file?

[Indy]

Hi,
I wanted to know if it is possible to copy the FS of your phone and create a .FBN file. What I mean is that can we create a backup file from our phone which we can also be used as a FS Flash file? If it can be done, then how?

I did read this thread:
Read Full Firmwares - Top Sony Forums
but I couldn't understand how I will create a .FBN file from it

....anyone???

I think you can extract particular files from the phone by FAR manager with latest plugin JDFLASHER from 31-12-2007.

I want to know how to create a .FBN file from phone too.

What for? It is senseless. If it would be desirable to make pack with all changes, combine all the changed files in one zip-archive for SETool.

but extracting all files with the FAR Manager is quite tedious. If you had a .FBN file it would be much easier to extract files using Main2Raw convertor.
