[DEV] sdat2img 1.1 - img2sdat 1.7 ◦ Unpack/re-pack android DAT files

Introduction
You probably know already that starting from Android 5.x (Lollipop) compiled roms (aosp,cm,stock) are not compressed anymore the way they used to be on previous android versions. On previous versions all content inside /system folder that has to be extracted within our device was either uncompressed (simple /system folder inside our flashable zip) or compressed in a system.img file, which it is a ext4 compressed file; both of these, anyway, were readable and we could see all system files (app,framework, etc).
The problem comes in >=5.0 versions, this method is not used anymore. Why? Because roms started to be always larger, so it is necessary to compress them even more.
What does new Android zips (full roms, but also otas) contain?
New Android flashable zips are made this way:
boot.img (kernel)
file_contexts (selinux related)
META-INF (folder containing scripts)
system.new.dat (compressed /system partition)
system.patch.dat (for OTAs)
system.transfer.list (see explanation below)​
What does updater-script contains then?
The updater-script uses a brand new function: block_image_update(), this method basically decompresses necessary files inside the device. Let's study it.
From google git source code, if we go inside the new file /bootable/recovery/updater/blockimg.c, we find at the end of it the registration of the function block_image_update() as the method BlockImageUpdateFn() which starts at line 254. Here finally we find all information we need to know about the decompression of the .dat file(s). First file we analyze is system.transfer.list which Google tells us:
The transfer list is a text file containing commands to transfer data from one place to another on the target partition.

But what each line means?:
First line is the version number of the transfer list; 1 for android 5.0.x, 2 for android 5.1.x, 3 for android 6.0.x, 4 for android 7.x/8.x
Second line is the total number of blocks being written
Third line is how many stash entries are needed simultaneously (only on versions >= 2)
Fourth line is the maximum number of blocks that will be stashed simultaneously (only on versions >= 2)
Fifth line and subsequent lines are all individual transfer commands.

Ok, but how to decompress the system.new.dat file?
All instructions are below. sdat2img, rimg2sdat and img2sdat binaries are involved. Please read carefully step by step.
NOTE for OTAs
If you are looking on decompressing system.patch.dat file or .p files, therefore reproduce the patching system on your PC, check imgpatchtools out by @erfanoabdi.
You can use/modify these files and/or include them in your work as long as proper credits and a link to this thread are given.
If you have questions or problems write here
Are you building from source and want to revert to the old flashing method without DAT files?

Ubuntu
Ubuntu 64-bit - Guide
Step 1 - Decompressing = DAT (sparse data) -> EXT4 (raw image)
We're now using sdat2img binary, the usage is very simple (make sure you have python 2.7+ installed):
./sdat2img.py <transfer_list> <system_new_file> [system_img]​- <transfer_list> = input, system.transfer.list from rom zip
- <system_new_file> = input, system.new.dat from rom zip
- [system_img] = output ext4 raw image file
and a quick example:
./sdat2img.py system.transfer.list system.new.dat system.img​by running this command you will get as output the file my_new_system.img which is the raw ext4 image.​
Step 2 - Decompress EXT4 (raw image) -> OUTPUT folder -> Compress EXT4 (raw image)
Now we need to mount or ext4 raw image into an output folder so we can see apks/jars etc.
To do this we need to type this command:
sudo mount -t ext4 -o loop system.img output/​As you can see there is a new folder called output which we can edit/modify/delete your files (not able to? see here)
Now we need to compress it back to a raw ext4 image, to do this we need the make_ext4fs binary. Make sure you have the file_contexts file (taken from the Rom zip) inside the make_ext4fs path. Then type this (got issues? see here)
./make_ext4fs -T 0 -S file_contexts -l 1073741824 -a system system_new.img output/​You will get the new raw ext4 image called 'system_new.img' ready for the next step.​
Step 3 - Converting = EXT4 (raw image) -> IMG (sparse image)
Now we need to convert the ext4 raw image into a sparse image. For this you need img2simg binary you can find here (thx to @A.S._id).
The usage is simple:
img2simg <raw_image_file> <sparse_image_file>​Pretty self-explanatory, the output will be a new sparse image (.img).​
Step 4 - Converting = IMG (sparse image) -> DAT (sparse data)
Now we need the img2sdat binary, the usage is very simple (make sure you have python 2.7+ installed):
./img2sdat.py <system_img>​- <system_img> = name of input sparse image file (from step 3)
As you can see the output is composed by system.transfer.list, (system.patch.dat) & system.new.dat, ready to be replaced inside your Rom zip.​

Step 1 - Decompressing = DAT (sparse data) -> EXT4 (raw image)
We're now using sdat2img.py binary, the usage is very simple (make sure you have python 3.x installed):
sdat2img.py <transfer_list> <system_new_file> <system_ext4>​- <transfer_list> = input, system.transfer.list from rom zip
- <system_new_file> = input, system.new.dat from rom zip
- <system_ext4> = output ext4 raw image file
and a quick example:
sdat2img.py system.transfer.list system.new.dat system.img​by running this command you will get as output the file my_new_system.img which is the raw ext4 image.​
Step 2 - Decompress EXT4 (raw image) -> OUTPUT folder -> Compress EXT4 (raw image)
Now you should either move to Ubuntu x64/x86 or follow the 2nd step from the Ubuntu guide on cygwin 32 bit.​
Step 3 - Converting = EXT4 (raw image) -> IMG (sparse image)
Now we need to convert the ext4 raw image into a sparse image. For this you need img2simg binary you can find here (thx to @A.S._id).
The usage is simple:
img2simg.exe <raw_image_file> <sparse_image_file>​Pretty self-explanatory, the output will be a new sparse image (.img).​
Step 4 - Converting = IMG (sparse image) -> DAT (sparse data)
Now we need the img2sdat binary, the usage is very simple (make sure you have python 2.7+ installed):
img2sdat.py <system_img>​- <system_img> = name of input sparse image file (from step 3)
As you can see the output is composed by system.transfer.list, (system.patch.dat) & system.new.dat, ready to be replaced inside your Rom zip.​

i don't think so, though you can install ubuntu in a virtual machine as 64-bit and decompress there without problems.
edit: windows binaries added to OP.

Confirmed.
Works perfectly..
Thanks a lot! This will save a lot of time theming.. (pulling the system, settings, framework without having to flash the rom first)
Oh, just for s&g's i extracted ("decompiled") the system.new file, the files (app, prive-app, framework, media, etc) all got placed on my desktop -- i deleted the system.new file from the rom -- i then placed the folders and files that got extracted and placed them in the rom -- i flashed it -- it booted! lol.. didnt think it would... but anyways, there's that.
For those who want to try:
--- > its basically self explanatory.
- once downloaded (the link above) extract the contents from the zip (i just went ahead and extracted to my desktop)
- right click the linux penguin
- run as administrator - the window will pop up
- go to file > open image > find your system.new image (should already be extracted from the rom and placed on your desktop)
- click open
- you should now see your image (or path) in the windows -- double click them (i doubled clicked both the right and left side)
- now you should be able to see all the folders
---> if you want to extract those folders
- just go up to the top
- click save and choose an extraction (i chose Desktop)
Hoped i helped -- any questions or confusion, dont be shy to ask -- i probably went too fast, idk lol
Enjoy!

I can't get this to work at all. I'm using Win 7 Pro and I've actually used this app before with stock Nexus 7 factory images and it worked fine.. What file did you actually download? I d/l 2 different versions, one was beta 2.0 and the other was a zip that said 2.2.71 but the about on the exe says 2.1, which is the version I've been using for quite a while.
With the beta 2.0, there's not even an option to open a file and with the 2.1, it errors out every time. After opening system.new.dat image and double clicking, it just hangs and the program stops responding. If I try clicking on it and selecting save, it allows me to select a folder to save it in but I just get a dialog box that says saving files and then hangs at 24% every time, finally crashing with a Microsoft C++ runtime error.
Oh btw, you didn't go too fast LOL, this is really a simple app to use but it's just not working for me with these block image files. Maybe I'm missing something but it's got me scratching my head. :laugh: If you have any ideas, I'm all ears.
Thanks,

ha! didnt even see there was a latest release..
i downloaded the 2006-8-26 apparently -- didnt even look at that date either LOL
i dont want to try the latest now -- this one works fine for me lmao -- dont want to ruin it.. ah, screw it, im downloading the latest now
EDIT: Ok, i lied.. i just checked my trash.. i did download the lastest release .zip .. the 2271..

@webdroidmt @Incredible_Culp Download from here lol: http://sourceforge.net/projects/ext2read/

Maybe something with my PC setup or Win 7 because the 2006-8-26 version doesn't even give me an option for opening a file image. It actually loads up looking like an incomplete application, it's also a very small filesize. Did you just d/l the ext2explore exe, or did you also d/l ext2read2 beta zip?

That's the one I've been using for quite some time. As mentioned in my previous post, the system.new.dat file just "appears" to be saving but hangs at 24%, then eventually crashes. I'm stumped, should be so easy but it doesn't want to cooperate. LOL
Thanks anyway,

Good.... ^^

It is a wonderful tool, brother.

is this tool works fine?

Getting error about incompatible operating system when recompressing dat so I tried on windows and got the same do I have to install the java or the phyton to a certain directory or the auto tool to a certain directory it extracted fine thanks in advance for the feedback

Can someone lend a hand.... Program works great. After removing a couple apps, one from 'app' another from 'priv-app', I made a zip file with 7zip and tried flashing but it fails. Is 7zip okay to make a zip file? was I not supposed to remove a 'priv-app' ? I can't find any solid guides on editing a MM rom. thanks in advance.

i succesfully unpack .dat files and repack .dat files (without edit anything) using this tool .
then i replace the repack .dat file to the rom and zip it and flash it .
but the problem is, when i flash i get error 7 system partition has unexpected contents after ota update . any solution ?

can't unpack system.new.dat cm14 （7.1）

Thank you very much, really useful

update - https://forum.xda-developers.com/an...tool-tool-unpack-repack-dat-img-v2-0-t3284806

Is it work for N based ROMs

tooolll
worked for me also...
t.y.

please update it to new version waiting for it.

updated with Nougat support
converts file_contexts.bin to file_contexts text file

My simple script - Python not needed
Hi chiragkrishna, thank you for the tool.
Unfortunately it doesn't work for me, it gets stuck on the file_contexts.bin
In light of this I made my own super simple bat file, that extracted the whole system folder successfully.
Then I went a step further and created a EXE from the provided python script, so there would be no python requirement.
But you do have to manually unzip the system.transfer.list and system.new.dat files from your rom (turns out, no other files required for Nougat).
My simple script:
works on Nougat (tested on 7.1.2 NitrogenOS)
no Python needed
just unzip system.transfer.list and system.new.dat files, and place them in rom folder
run start.bat

Please start a new thread. As I use many extractors nothing is extract my system new data but your tool done. Great.

How can I repack the modified system in system.new.dat after extracting?

I have no idea, these tools are just for extracting.
I see people are having trouble all over the place.

Thank you for the recommendation.I tried almost every tool available,but haven't tried this one yet.I'll give this a try.Unfortunately,I have to dirty build the rom everytime to get the changes done.Hopefully,this tool will maybe able to repack fine.

But you do have to manually unzip the system.transfer.list and system.new.dat files from your rom (turns out, no other files required for Nougat).
My simple script:
works on Nougat (tested on 7.1.2 NitrogenOS)
no Python needed
just unzip system.transfer.list and system.new.dat files, and place them in rom folder
run start.bat
Click to expand...
Click to collapse
getting this error

Hi chiragkrishna, thank you for the tool.
Unfortunately it doesn't work for me, it gets stuck on the file_contexts.bin

Oreo Contexts Converter

THIS TOOL IS FOR TESTING PURPOSE ONLY.
THIS MAY WORK ON SOME DEVICES OR MAY NOT WORK AT ALL.
IF THIS TOOL MAKES THE ROM UNBOOTABLE PLEASE COMMENT BELOW.
NO BUG FIXING not until i get an oreo supported phone for me to test.
TREBLE ROMS ARE NOT SUPPORTED!
FEATURES:
CAN DETECT OREO BOOT.IMG (YOU CANT MESS UP THIS TOOL. HAHA!!)
CAN DETECT WHETHER THERES A BOOT.IMG INSIDE THE MAIN FOLDER
CONVERTS BINARY INTO PLAIN CONTEXTS (MAIN FEATURE)
DECOMPRESS .BR IMAGES INTO .DAT (COOL RIGHT?)
USAGE:
GRAB A BEER AND RELAX
WHILE ON YOUR WINDOWS COMPUTER, UNPACK THE ARCHIVE AND GRAB THE OREO BOOT.IMG INTO oreo_contexts_tool FOLDER
RUN OFC.EXE AS ADMIN (NO NEED ADMIN RIGHTS FOR V2.0.0.1 AND V2.0.0.2)
FOLLOW INSTRUCTIONS AFTERWARDS..
IF YOU NEED THE CONTEXTS CONVERTER FOR NOUGAT THEN USE MY TOOL HERE TO CONVERT PLAIN CONTEXTS INTO BINARY AND VICE VERSA.
tested only on x32bit windows 7 ultimate
ofc v2.0.0.1
ofc v2.0.0.2
!!VERY IMPORTANT TO READ NOTES!!
Code:
v2.0.0.1
can decompress .br image into .dat
can compress .dat image into .br
NO NEED to run the application with admin rights, just run normally.
I added x64 bit application but havent tested it yet on 64bit machine
(my laptop cant run x64 os :p) if it wont work pls use the other application.
v2.0.0.2
file contexts output is current directory
added reset tool if experiencing errors
added clean current directory
less popup of cmd (only when unpacking boot.img)
x64bit tool is not included yet.
note:
choosing "clean current directory" option will delete EVERYTHING
inside the current directory except for the tool. so i advise to run this tool
inside a folder/directory to avoid deleting all your important files on your pc.
e.g you run ofc.exe in drive C:\ (C:\OFC.EXE) ...then you chose
"clean current directory" option, this will delete EVERYTHING in
C: drive so BE CAREFUL!! I wont be responsible if this happens..
if your anti virus detects malware, trojan, etc just ignore.. my script is very simple and basic that any highschool student can laugh at it. :silly: :laugh:

Extract IMG file firmware Huawei Device [Android 9]

Hello!
I want to extract the apk files from the system.img file HUAWEI P30 smartphone with android 9.
But the tool that I have always used (imgextractor.exe) completes the processing of the img file with an error:
Code:
ImgExtractor version 1.3.7 <Created by And_PDA (Based on sources ext4_unpacker)>
Extractor for images in EXT2\EXT3\EXT4\YAFFS2\CRAMFS filesystem formats
support SPARSE\SIN\MOTO structure formats
Exception EOutOfMemory in module imgextractor.exe at 0001669D.
Out of memory.
Please, help me!
P.S. According to the rules of the forum, I can not yet attach an external link to my post. But if necessary, I can send it to private messages!

Did you convert SIMG to IMG before? Something is in new format SIMG or raw IMG.
