Extract files from RUU Rom

Hi,
I searched around some here, but I'm stuck now... I have a Vodafone ROM Update where I want to extract some information/file from. So far I have managed to split it somehow with typhoonnbfdecode.pl, so I have some files that contain the different parts, as .nb files.
Where would I go from here, to get deeper into the image? Inside those files must be the cabs and stuff I think, how can I access them?

I'm not an expert on editing ROMs, but I also wanted to get the individual files out of a ROM upgrade, and this method worked for me.
I think you're looking for the utilities which were discussed and posted in this thread:
http://forum.xda-developers.com/viewtopic.php?t=34171
I used typhoonnbfdecode_v5 (only the v5 worked for me, not the other versions) then tools from the WM5 ROM Tools. The included tools.txt explains what you need to know, but basically prepare_imgfs.exe converts the nk.nb into imgfs_raw_data.bin, then viewimgfs.exe will dump the imgfs_raw_data.bin into the individual files from the ROM.

maybe I'm doing something wrong here...
typhoonnbfdecode.pl -x nk.nbf
!!! storedcrc=8f39f50f calculatedcrc=9cdb95a0
extracted OS_0
extracted Extension ROM_0
extracted GSM_0
extracted SPL_1
extracted IPL_1
extracted SPL_2
extracted IPL_2
extracted HTC Logo_0
extracted Splash Screen_0
prepare_imgfs.exe 9b000000-Extension.nb
Searching for IMGFS start... Not found!
So typhoonnbfdecode extracts several files from the .nbf file, but prepare_imgfs can't read it...

That's the same problem I was having until I found the typhoonnbfdecode_v5.exe. With the other typhoonnbfdecode versions, it looked like it was extracting the *.nb files, but they seemed to be corrupt.
I don't have the perl file that it was built from, but I found the compiled somewhere through a google search (can't remember if it was on the XDA forums or not). You can download it here http://www.exorzero.com/temp/typhoonnbfdecode_v5.exe

hm, funny... same result with this one...

How can I create a the META-INF files?

Hi...
I want to create my own update.zip from a original and clean RUU.exe I already know how to extract the exe file and all the other stuff that has to be done. But in the system.img arnt the necessary META-INF files.
I know its made with Android SignApk, but all Guides that I found show only how to sign one single apk. But it seems I need to sign all the stuff at once.
My question at the devs: How do you do this? And can I use my own key?

Don't know if can help you, but check dsixda's kitchen:

Dude, that's simple:
Pack all your stuff into an update.zip and then let run Signapk with the zip file as filename and it will sign it for you correctly by creating a META-INF folder and calculating all SHA1 checksums...

Thanks, finally I got a selfmade working rom. dsixda has some usefull templates for the update-script in his kitchen.
@TheSSJ
I will try that, but I guess the zip-file has to contain a proper update-script.

[HOWTO] Cook your custom rom for LG P500

Hi there, we are going to use excellent dsixda's HTC Android Kitchen to cook our custom ROMs for LG P500. The list of the things we are going to need:
Original ROM (Check this thread)
LG Utils 0.4.2 (Check this URL)
DzDecryptor v1.0b(Check this thread)
Cygwin (Check this URL
Unyaffsmbn (Check this thread)
Dsixda's HTC Android Kitchen (Check this thread)
Note: I have a "romcooking" folder on my home (C:\Users\Patricio\romcooking), inside i have all the utils needed, and the .kdz file for the stock ROM. I recommend to use tab to complete filenames since they are too long.
First we need to get a dz from the kdz (original firmware), extract LG Utils 0.4.2 and open KP500-Utils-EN.exe (You need to run this as administrator, or else you are getting an empty .cab file), select the I option (Extract files from KDZ file), and type the route to your .kdz file (Mine is C:\Users\Patricio\romcooking\V10A_00.kdz). Now, you must have a V10A_00.cab (Or another name, it depends on the stock rom you downloaded), open it with a extractor like 7zip or similar and extract the file "LGP500AT-00-V10a-EUR-XX-SEP-25-2010+0.dz" or similar to our romcooking folder.
Then we are going to uncompress the .dz with DZDecrypt (Press Win + R, type cmd and enter, then you cd to the folder where DzDecrypt is located (ex:
Code:
cd C:\Users\Patricio\romcooking\DZDecryptor_v1.0b
then we type:
Code:
DZDecrypt.exe "C:\Users\Patricio\romcooking\LGP500AT-00-V10a-EUR-XX-SEP-25-2010+0.dz" C:\Users\Patricio\romcooking\stockrom
This is going to create a "stockrom" folder in our original romcooking folder, you are going to see a lot of files in the stockrom folder, the important ones are boot.img and system.mbn (DZDecrypt should have merged your system.mbn_0, system.mbn_1 and system.mbn_2)
We need to install cygwin, open the setup.exe, just keep hitting next until you are on the select packages screen, go to "Devel" menu and select to install gcc, gdb and make, in "Interpreters" check perl, in "Archive" check zip and unzip, in "Web" check wget, in "Editors" check nano and vim and in "Utils" select cpio, util-linux and ncurses. Make some tea and wait for the cygwin install to finish and we are ready to go to the next step.
We are going to compile unyaffsmbn, copy the extracted files from unyaffsmbn, system.mbn and boot.img to C:\cygwin\home\Patricio, now fire up cygwin and compile unyaffsmbn with:
Code:
gcc -o unyaffsmbn unyaffsmbn.c
Now uncompress system.mbn, delete symlinks of bin/ and zip everything with:
Code:
mkdir system
cd system
../unyaffsmbn.exe ../system.mbn
find bin -type l -exec rm {} +
cd ..
zip -r stockrom.zip boot.img system/
We are ready to go to the kitchen (We have a stockrom.zip on C:\cygwin\home\Patricio, remember that)
Now we are going to use dsixda's HTC Android Kitchen, we need to have installed JDK. After we have downloaded and uncompressed the kitchen (Mine is in C:\cygwin\home\Patricio\kitchen), we need to put the ziped file we got in the previous step into the original_update folder of the kitchen. We are ready to go! fire up cygwin and cd to the kitchen location and exec ./menu , select option 1, you should see the zip file, put the number of it, and you are ready to go (It will create a WORKING_XXXXXX_XXXXXX folder, you can modify the files in WORKING_XXXX_XXXXX/system, add APKs, modify the apns file, etc).
This command also gives us a lot of options for our rom: enable root, add busybox, deodex our files, zipalign, etc. If you are going to edit text files, use an editor like Notepad++ or any other program that can open/edit/save files in linux compliant style. It's pretty easy to use the kitchen, just check the official thread for options or help
The common options i use are:
Add root permission (option 2), press f when asked and you are done
Add Busybox
Change name of the rom, easy cake
Advanced options, press 0
Add /data/app functionality
Add Apps2SD
Add custom boot animation functionality
Deodex files in your ROM
And Finally: Zipalign all *.apk files to optimize RAM usage
That should do the trick, when you are ready to cook your rom, just type 99, wait for it to build and it should be in the OUTPUT_ZIP folder in your kitchen folder.
Took info from this thread (About decompressing .dz and .mbn, and making it to work with the kitchen), and info from ruigui and tritant in this thread. The awesome android kitchen by dsixda. Sorry if i forgot to mention any work, just post it or pm me
If you have anything you want to add to the guide, just post it

You don't need to dual boot to linux. It can be done with cygwin.
When you follow dsixda's guide to install kitchen, do as said but don't install cygwin from that guide.
Instead, download from official site, choose default options, but add these packages (it will be compliant with kitchen and give a little extra funcionality):
Devel: gcc, gdb, make
Interpreters: perl
Utils: cpio, util-linux, ncurses
Archive: zip, unzip
Web: wget
Editors: vi, nano
Good guide, nicely done
EDIT:
In my wife's machine (using windows 7 64bit. i'm without computer, for now....), i've installed cygwin as said above.
Then added two folders to my home dir:
kitchen and unyaffsmbn
In kitchen, use the kitchen
In unyaffsmbn, copy the files from unyaffsmbn.zip to that dir, then compile it there
EDIT2:
If you edit text files under windows, USE NOTEPAD++, or any other program that can open/edit/save files in linux compliant style.
There are differences in Windows and Linux when ENTER is pressed, and you'll have issues when trying to flash or run your custom ROM

hi there... thanks a lot for your guide.
I'm trying to do the things you wrote step by step... I have extracted the dz file successfully, then I extracted the content using DZDecrypter... I found three files called system.mbn0, system.mbn1 and system.mbn2. The first and second are 80 Mbytes, the third just 17... Which one is the correct? When I try to use the command "unyaffsmbn system.mbn" (obviously I renamed the first and then the second) I get an error message ("impossible to execute binary file", or somenthing like that... I don't know how's in english because I'm italian).. Is that concerning to the presence of those three different files? Did somethind go wrong with the extracting process? Or maybe I didn't do somenthing important? Before doing this, I installed "build-essential" and did "gcc -o unyaffsmbn unyaffs.h" but apparently nothing happend... I got neither errors nor processes...
can you help me?

Awesome bro, I can try to make custom rom with indian version, ty.

you shouldn't get three system.mbn files, did you used the 1.0b of DzDecryptor? when i used it, it said something about merging, i think that it gets the three files and then combines them to get a proper system.mbn

I used the downloaded version from the link you posted. At least I guess... :/ Well I'm going to try again soon! Thanks a lot again for your guide!

Other methode for exctract mbn file, not need to connect the phone.
Windows only....
(1) Download LG-Utils 0.4.2: http://www.assembla.com/spaces/ks360...tils-0.4.2.zip
(2) Run KP500-Utils-EN.exe (or whatever language you prefer out of the available choices) and select I to extract the KDZ.
(3) Open the resulting CAB file and extract the DZ file.
(4) Download DZExtract: http://www.frenchcoder.com/upload/DZExtract-V0.2.zip
(5) Use DZExtract to extract the MBN files:
DZExtract -x GW620RAT-V10c-OCT-21-2009-RGS-CA_DZ+0.dz C:\extractedTo\

after compiling and chmod I do:
Code:
[email protected]:~/work/unyaffsmbn$ unyaffsmbn system.mbn
unyaffsmbn: command not found
both files are in that folder. Am I doing anything wrong?
Cheers.
@tritant - LG-Utils link not working

So.... You MUST compile unyaffsmbn first. Only then you'll have an "executable".
Code:
gcc unyaffsmbn.c -o unyaffsmbn
Then copy system.mbn to unyaffsmbn folder.
After that, do:
Code:
cd PATH_TO_UNYAFFSMBN
./unyaffsmbn system.mbn
You missed the ./
You can download lg utils from here

It was a typo in first post (he switched file to be used in gcc).
Give the man some time to reorganize his thread

I did not mean to be rude by any means!
I appreciate the effort to create the how-to! Hopefully people will read the thread if they get stuck and use the right commands so that they don't abandon the idea of creating their own ROM

I also didnt want to call you rude... Sorry...
But we were exhanging some pms and he is redoing this tutorial.
Sometimes we make mistakes while typing long posts

thanks for this great tutorial
everything works like a charm , but when i flash my new rom i have an error says no enough space while writing boot image
any idea?
Update: okay i solved the problem, it seems that i missed up with the boot settings!

I finally made the zip file, but when I start the kitchen and select it, i find this:
"Warning: No META-INF folder found under working folder!
Warning: No META-INF/com/google/android folder found, creating it.
Did not find an update-script. Shall I create one (y/n)? (default: y): "
is that normal? and what should I do? :/

[Q] (Q) How to collect smart flash flashable file from kdz?

Hi guys, i searched lot, but did not find any proper solution for getting flashable files of smart flash from kdz..
Plz help guys..

Obviously you haven`t searched enough .
I think that you are looking for LGExtract 0.2.1
Tool is in it`s beginning, but from reading I think that it can extract smartflash files from kdz and it is tested on p990 (I haven`t tested it).

k, i tried that, now i got 13 files.
some are img, some fls etc.
but we need only 2 files for flashing with smartflash tool. bin and fls.
how to get them ?

As I said, I haven`t tried to do this, hence I can`t help you. You will must to read and ask for support in original thread, where the author of the tool is present.
If you are trying to flash kdz and since LG have changed their politics, try to read this thread too... http://forum.xda-developers.com/showthread.php?t=1473781

Hi all,
first, thank you Memhis, the tool is excellent. It works under Linux too in Wine environment.
But I have some observations and some questions
- first decrypt/decompile KDZ file only extract a CAB file - this CAB file can be extracted by cabextract utility
- after CAB file extraction, there is WDB file and machine specific DLL - this DLL file must be used for extraction of WDB, I try the newer one without success
- after performing extraction of WDB using DLL there are number of files which can be useful
AENEAS_FW.fls, psi.fls, R375_SIC.fls, slb.fls - these files are the baseband and can be flashed using smart flash tool - it must be flashed all, not only some
#_Split_Data.img - after joining this file to one, it contains Linux filesystem (now EXT3) with all data of /system partition and you can get lge-ril.so from this
The remaining files I don't identify and only speculate what is it
ext3_flashboot.img - this filesystem is used to boot for flashing???
fastboot.bin - ???
recovery.img - recovery partition - this images is used to replace ClockWorkMod I think
Once again, many thanks. I was searching for this similar tool about six moths ago.

can you tel me,how do you extract the split_data.img??
at this point i have no idea what i must do and find nothing about it.

There is nothing to "extract" from split_data.img. It is a true EXT3 Linux filesystem. You have to use a Linux box or something to allow mount an Linux image to Windows environment. I can only point you to http://www.ext2fsd.com/ site which is free good ext2/3/4 filesystem driver, but I don't know, if it is usable - it can mount a Linux partition under Windows but don't know it can mount a image file as disk. Hope so.

Thanks for the information, but I can't extract Split_Data.img (it's the joined file of 4 .img files).
How can I extract this .img in Linux (virtual machine)?

You have to mount it, like it is a whole filesystem. Google it to find out how to mount img file. Once done, you'll open it like a hard drive.

Edit: Forget my question, it works now!
My last question: Is the file "ext3_flashboot" the same as the boot.img files in CWM roms?

OK, I managed to extract the kdz file and I made a rebuild of V20c without flashing the kdz, just with extracting!
I'll upload it in a few minutes!

For those who wants to extract KDZ I prepare a little manual...

Hi Keltek, thanks for the manual. but i am getting some error, any ideas? I'm using Win 7 32-Bit. This is the error:
C:\>LGExtract -kdz V20F_00.kdz
Extracting:
KDZ: V20F_00.kdz
Failed to create cab file.
Error code: 00000005
Message: Access is denied.
Failed to extract file.
Please report this error with this file.
thanks
NEVER MIND: cmd.exe should "Run as Administrator", it works now.

The last question I have is how to join the 4 extracted baseband files to one file?
Does that work with copy /b command?

What i got from flashing basebands is that youre supposed to flash them one by one from largest to smallest file. so basically what you should be doing to "compress" the procedure is you unpack those 4 files, put the largest one in place and copy the others onto it, replacing duplicates. Then repackage what you merged, and try that, cant think of anything more logical than that.

That sounds logical, but I don't know how to extract the files.
But it's not very important, because it isn't a problem to flash 4 files instead of one.

Please extract Bb from v20h rohan

If you give me the link to the kdz, I will extract the baseband for you.

You should specify from which ROM file, coz there are many version with same identification but different content - I don't understand why LG do this - the V20q for Czech Republic is not the same as V20q for Italy...
I take a look at V20h and it contain 1035.21_20110725 BaseBand.

Tweaking rom - begginer question ;)

Hi!
Since xda-univeristy arised i thought it would be nice to learn something about green droid
I am going to learn about tweaking and theming:and here comes dozens of my questions:
1. I have downloaded Official ics repack by N00BY0815
2. I extracted it and i have:
2 folders ( META-INF and System)
2 files boot.ing and system.img
How can i extract this system.img ?
I tried to use 7zip but it says that" it cannot open it as archive"
Thanks in advance and please for leniency

it can be opened with Diskinternals Linux Reader. if not. use "sgs2toext4.jar" to convert it to .img.ext4 and then open it

Everything for theming is in the System folder. All the APK's(Applications) Boot.img is probably the recovery image it installs. But to theme you would need to decompile the apks in the system folder

You can pack them with the android kitchen, install the zip, then you do this in terminal emulator to make the system.img file:
Code:
su
cat proc/mounts
now look up the system partition, in my case it's mmcblk0p14
Code:
dd if=/dev/block/mmcblk0p14 of=/sdcard/system.img BS=4096
This will dump the system partition to system.img (for example when making an odin image)
