What is the difference between .nb1 and .nbf - MDA, XDA, 1010 Software Upgrading

after I cooked ROM from Jeff Summer's Kitchen, it has the option to choose whether you want it .nb1 or .nbf
.nb1 is for SD card flashing
while .nbf is for advanced users...
so what is exactly the difference between this 2 extensions??

Good Q - I was finkin that 2
Keen to always b learning more. Would appreciate a response to add 2 d knowledge for which without this site I would be stuffed wit an XDA still stuck on d update screen

an nbf file contains some information about what kind of device the os image
is intended for, and a bootloader and the os image.
a nb1 file contains only an os image.
nbf's can be flashed with Programme A.
see http://www.xs4all.nl/~itsme/projects/xda/wince-flashfile-formats.html
osimagetool understands both nb1 and nbf files.

Do you mean if I flash the phone with .nbf via osimagetool ( Programme A) , it could be over-write bootloader ?

yes, it could. but osimagetool will not take the bootloader from the nbf,
it always puts the 5.15 bootloader in the file that is flashed with "Programme A"
for a reason I don't yet understand, the bootloader is not always updated.
I am quite sure that "programme a" used to update bootloaders, but I have not seen it do this for some time. - maybe it has to do with the rom version?

Rom Image Tool

The irish O2 update includes "NK_Wallaby31413wwe_O2_Full.nbf". This is I assume the ce-rom part. Which file is the bootloader ?
If the bootloder is in fact included in the above file, what should be ticked & selected to write this to the SD card ?

Start XDA ROM Image Tool. Select 'Write to SD card'. In the box, check both bootloader and Windows CE, in both boxes select the name of the .nbf file. Select the header type for the bootloader that is currently in the device, and remember that you'll need a little more work if the device has a 5.17. (Downgrade to Bootloader 5.15 or 5.14 if you can).
You can, after doing this, save the bootloader and CE part separately to XDA-developer format, as .nb0 (bootloader) and .nb1 (CE) files. Ofcourse you really shouldn't need to first write it to SD to do this. But hey, nobody's perfect...

mkrom questions

Hi,
Just two questions.
1)I runned the Mkrom.sh and when building it it comes with the
error ' operator rom not found' but continues.
Then there's only a .nb1 file build which has a size of 32,243,712.
I don't know if this is correct !????
Is it a problem the operator roms are not found for a working rom???
2) Is it possible to delete, maybe even extract files from an image to
clean it so you get more space for your own programs?
hopefully any can answer these......

There should be both an nbf file of 32505888 bytes and an nb1 file of 32243712 bytes. So the size for the .nb1 seems correct.

I'm not sure I understand the problem enough to be sure. Itsme, who made the tool, has left for a well-deserved two-week holiday, so I guess this will have to wait if you can't figure it out for yourself.
2) Is it possible to delete, maybe even extract files from an image to clean it so you get more space for your own programs?

Yes, extraction is possible using the dumprom tool described in another thread. Deletion of files to save space would take some hacking and slashing of your own. We do plan to make some more intricate ROM manipulations more easy once we clean up and publish more tools.
@XDA developer Peter Poelman
I'm glad the size is correct.
Just tried it again and only the .nb1 file is created, not the .nbf !!!
Is it possible to convert a .nb1 to a .nbf file??
Is the XDA ROM Tool able to write to USB SD-card reader/writers?
(could be an option to generate a valid .nbf)
thx
[ I split this topic away from the main Special Edition v1.1 thread, as it's not primarily about that. I will probably start doing this more as topics grow larger. ]
Yes, you can use XDArit to write an nb1 to SD, and then read SD to nbf. Easier tools for this exist, and we've even built the beginnings of one (which we haven't yet released).
If you have the SD, you could also just use the bootloader to burn the contents to flash.

Unlock SX56 Rom Ver. A.30.09 Eng

I Syncronized the XDAUNLOCK to my AT&T SX56 but when I tried to run it I got "error getting unlock code" can you help...
Thanks :roll:
Backup your existing rom to sd card, install developers rom special edition, this will unlock the phone, then flash original rom from sd using bootloader method.

is there another method to install developers rom special edition b/c i tried to cook up a new rom after being redirected to www.yorch.net but 1st my rom version at&t A.30.09 eng is not listed does it mean i can't do it
2nd i used the 3.17.03 ENG O2-Euro hoping to overwrite mine but i could only create an exe not an nk.nb1 or the .nbf file

Yea use Winzip to extract the .exe then you'll have direct access to the .nbf file! :wink:
HTH

i extracted the exe file to a new folder but there was not an .nbf file or at least i couldn't find one :?: :!: :?:
thanks
there is a subfolder named english. The NK lives there.
i found the nbf file i had to extract onto itself
i'm using the bootloader to do flash the new rom to my phone
i'm at the step where the device is suppose to recognize a new rom on my sd card
i copied the nbf file using xdarit
i plugged the card back into the pda
now i start the wallaby bootloader im running v5.15 it supposedly should recognize the new rom well the instructions say to copy the .nb1 file on the card but with the extraction method i could only get a .nbf is that why it's not being recognized
thanks
thanks guys my phone is free .... free as in unlocked
these are the steps i took
someone can do in 30 mn what i did in 1 day
-backed up my rom onto a sd card with wallaby bootloader v5.15
-using the xdarit i downloaded my old rom on my PC
-cooked a new rom with xdaunlock at yorch.net
-couldn't create a .nb1 or .nbf file so i took the .exe rom
-with winzip extracted the newly dowloaded rom onto itself to get the nk.nbf file to be flashed (when i extracted it on a new folder there was no nk file listed, so i went back to the kitchen cooked another rom saved the exe "et voila")
-i couldn't get the newly upgraded rom to be recognized when using the bootloader
-downloaded the xdatools to copy the nk file on sd card (i was unable to pick my sd card reader as a destination -weird stuff) so i did this
-from the english folder Abbas is talking about above i right click the nk file to copy it to SD card and xdatools was launched automatically
-plugged the sd card in the phone and started the bootloader v5.15 and instantly the rom on the sd card was recognized
-press action to download it
-cold reboot ( the battery on/off, erase all)

All tools in XDA-developers.com cannot unlock SX56 radio A.33.02 or T-mobile 6.25.02
I developed a new tool to unlock them.

Maybe they should downgrade their radio, then unlock and then upgrade the radio and rom again. I think that is the new tool cgigate developed!

Extracting files from ROM

I have an iPAQ hx2790 (JPN) with WM5 and I was wondering if someone can point me in the right direction of extracting files from the ROM area. I did some searching and also looked at the WM5 ROM Tools thread, but I tried all these tools in vain. I tried dumping a ROM image from my ppc (using the tool that auto-dumps ROM into storage card) and extracting that but it didn't work (I believe it locked up). I tried dumping the original .nbf ROM upgrade file provided by HP but that didn't work as well. I just need to extract 3 .dll files so if someone can point me in the right direction, I'd greatly appreciate it!
You should decrypt NBF file, then the tools would work.
Currently there is no decryption tool available, you should make it yourself.
I don't remember the encryption used in HP NBF format, but it should be simple, maybe XOR with a constant string, and maybe some garbage added after each block.
Thanks for your reply mamaich, I didn't know HP's NBF was encrypted. Is there source code for a decryption tool someone made for another NBF format already?

nbf filrs

This is a dumb question but what do you need to get .nbf files to your 8125 pda phone.

nk.nbf file is the OS (Rom) it requires a tool to flash it to a device which is RUU (RomUpdateUtility).A Rom is a complete compressed package,which includes OS(nk.nbf) and flashing tool RUU(RomUpdateUtility).Its the flashing tool RUU,which you execute to run the rom and flash it to the phone.
I presume you need to do alot of reading and understanding all these terminology and process of flashing
