[Question] How to unpack/repack DHD img files? need a guide.

ok here is my question..
im trying to extract the system.img files to restore some of the original files i changed.
here is the things i want to know in a list
1, Which tool is used to extract those IMG files? guide please. if you do need to compile it please post guide on how to compile as well?
2, how to repack the files into readable Img files which we can use to fastboot flash system with?
3, the shutdown.zip and downanimation.zip what are the requirements? i have sucessfully made a custom bootanimation.zip but failed the downanimation and shutdown. the bootanimation works when i made zip file with store only attributes "no compression", but the other 2 wont work either way..
if i can get this information i would make a general thread about DHD with all the information so it would be easier for anyone to find out all about xda and the development for DHD
example, Radio/Eng S-Off CID-1111111 simunlock, adb commands/tools/guide, cygwin/unyaffs GIMP etc including graphical mods and specific how to's.
please help me out this might reward the newbies alot saving loads of precious time searching.. just like me
rofl edited to change adb to fastboot. sry my bad. stupid typo ;x

[TUTORIAL] How To Extract Files From a TAR.MD5 Stock ROM (SPH-L710)

I recently did this for the E4GT and have been asked to do it here as well.
I've received a TON of PM's and emails asking how to do this and I've decided to do a write-up for everyone. Now to start off, this does not automatically make you a Super Duper Developer, this does not show you how to make your own TAR ROMs, nor does it show you how to make your own Odin One-Clicks. What it does do is show you how to pull files from those stock leaked/official ROMs so that you can proceed to make yourself into a Super Duper Developer!
In essence if the Developer knows what they are doing they could use this method to extract all the files from the build and could then add them to a ZIP and have a stock odexed ROM within minutes and do it all through Windows! Depending on time I may or may not do a tutorial on that as well...
So let's begin!
We've all seen those pesky TAR.MD5 packages that we can flash through Odin. How often have you wanted to look inside them and see what is inside before flashing? There are several ways to do it and the most common answer requires Linux and Dsixda's Kitchen utility. This tutorial gives you the ability to do that through Windows and without having to extract the full ROM. These instructions are specific to the Samsung Galaxy S3 (all variants) but can be used on most Samsung Galaxy phones.
Each TAR.MD5 release contains multiple files. Each of these files corresponds to a specific partition on your device. These files are formatted to be mounted by your device but not by a computer. We will be converting them from a .img.ext4 partition type to an ext4.img type partition so we can mount them and read them through Windows. For this tutorial we will be opening up the system.img.ext4 (the system files partition).
Before you dive in there are a few things you'll need.
- A PC running Windows.
- A stock TAR.MD5 release. Several are available at www.rwilco12.com.
- DiskInternals Linux Reader (must be installed on the Windows PC). You can download DiskInternals Linux Reader here.
- SGS2toEXT4 Utility available here. *Be sure to extract the JAR file from the ZIP archive.
- 7-Zip available here.
For the rest of the tutorial please visit my site: www.rwilco12.com
Enjoy!

Unfortunately no. That part does require Linux but this could help simplify the process if you prefer a Windows environment.

You need to extract it from the img file by saving it. After extracting you'll need to package it in a ZIP.

I followed the guide to the t and its saying that the image is invalid. Any ideas?

What device and what files are you using?

Using windows Vista x64 the file is a I537UCUCNE3 stock odin image. I created a .img file using ext4 tool you posted but the Linux viewer says invalid

The image here shows my created .img file on the left, the Linux reader on the right and the error in the middle

This tutorial is no good anymore.

Finally !!
I found how do that after to waste a day to search one real solution.
Is only to use the ClassyKitchen free version for windows.
I found it here:
https://forum.xda-developers.com/chef-central/android/tool-classykitchen-android-roms-t3862584
Basically, after to open the program, you will choose "create new project" on the tab "Projects utils", and choose the firmware from PC or from mobile root. So, the program will extract the folders and files to PROJECT/system folder, and you will can access them by windows explorer, including the app folder with all original apks.
I was looking for a way to restore the calculator apk after delete it before to find another to replace it.

[Q] Extract Boot.img from Stock ROM

Hi guys, I would like to extract boot.img from a Stock ROM without the need of installing it on my (Galaxy Note 2 T-mobile). All I found on the internet is how to extract it from an installed ROM.
So I would like to:
1. Extract the boot.img
2. Then flash it through ODIN to my custom ROM (Jedi Master 14)
Thanks in advance and please help me :crying:

Why would you do that?
Hastily spouted for your befuddlement

I don't know how you going to use boot.img to fix your problem. But the .md5 rom files are just zipped files. unzip and you will find the boot.img file. Are you sure that this will fix your problem?
Are you trying to change your boot image?

Use a tar archive program (7-Zip, Winzip, Winrar, PKZip, this format is pretty universal) to extract what you need from the official Samsung ROM images. (Check out sammobile.com if you haven't already, you will need to register.)
You might get some error message about the end of the archive, that's normal and due to the presence of the MD5 hash at the end of the file, which most programs will be able to work around nonetheless.
Repack the relevant file with a *nix tar binary, or under Cygwin on a Windows machine. (YMMV, but those are the two only ways I've managed to have the files work with Odin.)
Reboot phone to download mode and flash with Odin as usual.
Done.

Thanks a lot. Thats exactly what I am looking for.

issues with update zipping

Hi all, having a strange issue with a signed update zip file.
i have an update i need to modify, i made the changes and signed it properly, but update failed.
to make sure, i just unzipped the original file and zipped it again (no changes and all signatures shouldn't change) - update failed AGAIN.
(BTW i also tried to sign after zipping, that didn't help as well).
the original zip and the new one aren't the same size, but when extracted all files are identical.
would appreciate any direction here..
some specific info - i'm trying to modify a connected car (FlyAudio) update file, the recovery is proprietary so there's little info on why it fails.

Typically, update.zip files are recovery flash files and ODIN doesn't flash zip files in that manner.

ok, so the problem is that the update.zip (it has a different name but it's an 'update.zip' file) wasn't signed.
after extracting, zipping, signing i'm getting a file that's ~1K smaller than the original and identical up to that point.
the tool i'm using to sign uses test keys so i assume it's a keys issue.
--------------------------
update - needed to sign with -w (signapk option) that added the required footer.
thanks all
