I want to extract the system.img.
I have win xp 32 bit.
I tried to extract using pre-built win unyaffs.
But failed.
It only creating "unyaffs.exe.stackdump" file
Error:
Code:
2 [main] unyaffs 852 handle_exceptions: Exception: STATUS_ACCESS_VIOLATION
817 [main] unyaffs 852 open_stackdumpfile: Dumping stack trace to unyaffs.exe.stackdump
Help me.
Use unyaffs-x86-win from here.
And the unyaffs system.img. It worked with the official HTC WWE 1.67.405.6
rom.
Found it in this tutorial.
Yes,Man.
I got it.
First i tired it on backuped system.img form mainframe3 custom recovery.
Not to mention that I got you out of this pickle.
For some reason, unyaffs doesn't like backuped system images...

That's right. Unyaffs seems to have problems reading images that have been altered.

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...
My default browser went foobar on me when i tried to go into the about menu.
Could someone upload the 2.1 apk and odex pls.
Thanks
EDIT: Changed the topic name to reflect the newly found utility that helped me recover my files since. I had no current backup and did not want to start from scratch. Figured it could help if you ever find yourself in that situation or want to extract files from other rom backup.

Did some digging around and found a nice utility to extract the files from the .img. Extracted the system.img from the stock rom unpackaged it with unyaffs.
Here's the utility
Code:
Usage: unyaffs name_of_file.img
WARNING **This will extract all the files in the working directory**
HI,
I am trying to get an apk from a KDZ file. I can open up the KDZ but then there are many other files inside. I guess the apks are in one of these other files. Does anyone know how to get the apk from within .img files etc?
Thanks

How you extracted KDZ?
Why don't you get it from the sapps module zip on void's rom?
I need a particular app from the Orange UK ROM - the app is called Signal Boost and it is for UMA calling.
Is that app in the ROM you mention?
What you need is this: http://forum.xda-developers.com/showpost.php?p=6303911&postcount=827
It allows you to decompress system.mbn (where all the files are).
Compile it under linux, or use cygwin.
Remember that official ROMs are odexed. If you want to deodex apks, you can use dsixda's excelent kitchen. It is used to make lots of ROMs you see around here.
For that, take a look here (you can also use it under cygwin):

Many thanks, I will see if I can get anywhere with this.
You just need to compile unyaffsmbn (gcc unyaffsmbn.c -o unyaffsmbn).
Then copy system.mbn to unyaffsmbn folder. Then do:
./unyaffsmbn system.mbn
You'll have all files extracted in few seconds.
Then if you want to use those files in kitchen, do this:
First install kitchen, as explained in link i posted above.
Delete all symlinks in bin/ (i think there are 52)
Then you must create a zip file with this structure:
/boot.img
/system/ (here you put all the files you extracted. You should have 10 folders and 1 file)
Now just copy this zip to PATH_TO_KITCHEN/original_update/
Then run it with:
cd PATH_TO_KITCHEN
./menu
Right I have three system.mbn files named:
system.mbn_0
system.mbn_1
system.mbn_2
I have tried a few tools (under Windows) to extract them. Firstly a windows compiled version of unyaffs which falls over with : Exception: STATUS_ACCESS_VIOLATION at eip=61100F73
I then tried another version which didn't error but also didn't do anything!
A different tool errored with "the header states that its binary is longer than the whole file" which makes me think perhaps these three files need combining into one?
I have tried combining them into one file using the copy /b command in Windows which creates a single large file but I still have the same issues trying to unpack it.
Any more ideas? Thanks
Right have now installed Cygwin and managed to extract the files using unyaffsmbn! Thanks for all your help, learnt a lot today!

How did you decompress kdz? I use LG Utils to extract to dz, then dzdecryptor to decompress dz to individual files. Then i use the tools i named to do the rest of it.
Also i can see that lg utils finds those system*, but puts them together before it ends. Maybe you used different software.
Anyway, i'm glad you managed to work it out

There is unyaffs, and unyaffsmbn. unyaffs also never worked with me.
I've read somewhere that with lg roms we must use unyaffsmbn. Don't remember were i saw it, neither why...
I used LG utils to extract the KDZ, then used DZExtract to expand the .dz file. Then I combined the system.mbn_0,1,2 files using copy /b.
I then used Cygwin and gcc to make unyaffsmbn.exe which then worked on the combined system.mbn file. Managed to get the apk I needed too.
PLease upload unyaffsmbn.exe for me please as i seriously need it.
Here you go...
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!

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.
Hi! I need a very specific system dump to try some mods, Unfortunately most of the tools I used no longer work. I tried with Ext2explore, Ext4Unpacker and some others but they all give a error message. What is the correct method for doing a Samsung system dump? I'm on Windows 8.1 (x64)
I guess I found the perfect tools right here on XDA: https://forum.xda-developers.com/s6...ol-tools-file-extraction-img-tar-md5-t3236605
Download the tool and unzip. Extract the system.img file using WinRAR o 7zip. Drag and drop system.img into NEWIMG2EXT2 This will convert the .img into a .ext4, to be opened with Ext2explore. Now that you have a complete dump you can deodex and start tinkering.
