I tried using 7zip, extractnow and some random program I found on google called ext4_unpacker.exe. I want to extract the system and dig through and edit the files and the same thing with the modem.
I get cannot open as archive with 7zip, "unknown file format" with ext4 unpacker and it just won't open with extractnow.
thanks for the help in advance. and apologies in advance I know this is super noobish but the programs just won't work :crying:
Use adb to pull the files then use a hex editor?

I'm assuming you mean pull them from the phone? Also I still want to be able to extract the files so I can examine older firmware versions, being that I'm on 4.4.2 stock.
So my question still remains, how can I extract the files?

I want to open up a system.img from an older bart backup to extract a couple apps. How can I do this? Seems like any archive program doesn't want me to open it.
Yeah you can't actually extract apps like that. You would have to flash the system.img, let it load up, and back up your .apks from there.
Another method that I have never tried for myself is to mount the system.img in the sdk emulator and see if that gets you anywhere.
If you are on linux, you can use the unyaffs to extract the contents of .img files.

a month and a half later, but thank you! This will be useful in the future.
Ooh yes that will be useful for me as well, thanks!
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...
recently i tried to replace the kernel that came with a version of Phoenix with an updated kernel before flashing, but it did not work out. I simply extracted the original, replaced the zimage, and created a new zip file with the new kernel in the rom, using windows to package the zip. is this what i should do, or is it more complex than this? the flash failed.
Don't extract the rom zip. Use 7zip or similar and open archive, delete the zimage then drag the other kernel zimage in there. Or just flash the rom as is and then flash the kernel.

thanks! that makes sense. can i just do what you said using windows explorer?
7zip is free and handles many more file extension types.
Install it then right click on the file in windows explorer, select 7 zip, then open archive. This allows you to make changes without actually extracting the entire file.

yes i know, but when just dealing with a zip file, can i use windows explorer to delete contents inside the zip and replace them?

so when i double click on a zip file in windows explorer, and it opens it as if it were just another folder, can i not replace stuff directly in windows explorer where im at?
That extracts everything and you may have issues after zipping it back up

in windows explorer, you can right click and select extract files, but when you double click the zip it appears that it is allowing you to edit the contents without completely unzipping. am i wrong in thinking this?
Perhaps you can do it that way......i just always used 7zip. You will have to try it and see.

alright, thanks bud =D
I am using winzip. When I right click the zip file it gives me the option to "open" with winzip. When I do it shows me files like windows does. So my question is can I use winzip to replace the file and then close it?
winzip works as well
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
Everythink was in system folder in gingerbread, in this system folder i have only app folder with su.apk and bin folder with su file.
So files i need are in system.img
@broodplank1337 thanks for help, program works well, now i can begin
But first only one question, now i can extract files, but can i pack them using same tool ?

I don't know much about S2 but can't you just use 7zip to make it an archive and flash it through rrecovery?

Hi. You can use dsixda's Android Kitchen for that.

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)
I've been looking through a couple of xda thread about it, found a few solutions. I managed to unpack from the .tar file, got the img.lz4 file and from that the .img and from .img to .img.ext4, but the .ext4 file is too small compared to the original .img file, so I guess the older SVAImgUnpack doesnt do the job correctly and can't open it with ext2explore. Is there any other software to use for this?
Nevermind, I've found a program for it.
