Howto edit a .nbf file?

[Pibbs]

Hi all,
can you explain me how to edit or convert an nbf file, (in the specific, a fsc n560 rom WM6.0) to view the rom content?
I found many applications for HTC models, but noone was good for my rom...

thanks for the help, but..
nbf it's not an archive. if you try to open with winrar it will open like an unknown file...it needs to be decoded and opened with a hex editor I think...

I think you have to use HTC64_Extended_ROM_Tool.exe to decode your nk.nbf file, you will obtain nk.fat and nk.prj. Keep nk.fat, rename to os.nb and go on with imgfstools. I hope it works in this way.

I've tested this steps with a HTC Universal rom and it worked, then you can extract the os.nb file in a veru simple way with Bepe's "dumprom.exe", after this use PackageTool and you will have SYS and OEM folders.

sorry but, it can't work with this file...if i do directly with dumprom with the nbf i can extract 2.02 mb of files (i think the bootloader cause the list of files names are all similar boot*...something).
If i use htc64 doesn't work at all...it makes an error extracting just 512 kb...without any sense...
please could you try with this file, if i make some errors...?

SOLUTION!

Ok,
I've downloaded your file and tested. To extract the os.nb do this steps:

1) open your os_213U.nbf with an Hex-editor, from the start you will see this:

[COLOR="red"]4E 35 36 30 00 00 00 00 00 00 00 00 00 00 00 32 
2E 31 33 2E 30 30 30 31 20 45 4E 47 00 00 D7 07 
58 F3 00 00 0C 02 00 00 04 80[/COLOR] E9 FD FF 00 00 00 
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

2) cut all these red bytes, then your file will start as this:

E9 FD FF 00 00 00 00 00 00 00 00 00 00 00 00 00 
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

3) save this file as "os.nb", then you will go on with dumprom or imgfstool!

That's ALL!
I think that you can edit your rom and at the end you have to reinsert those red bytes at the beginning of your new rom and rename to .nbf.
