Hello .
Posting a tutorial on how to create a dump out of your stock rom, in case you delete some apps or modify some settings.
ALRIGHT LETS START:
STEP ONE:
Alright, so you want to make a backup of your phone software, but dont know what to do. Its simple, download the package the Android SDK from google and copy it to C:\ drive. Once you have download it, make sure you have Java installed in your system or else it will not work. After everything is done, open the program and install these two packages:
1. Android SDK Tools, revision 6
2. USB Driver package, revision3 ([COLOR="Red"IMP: Its important that the USB driver installed shows up as Composite Android Debug Device, else it wont work. ][/COLOR]
What Android SDK ?? Read about it here: [url]http://developer.android.com/sdk/index.html[/url]
Why Android SDK ? Because: it has the [COLOR="red"]android debug shell[/COLOR] which you require before communicating with your android phone. So download it ! From here:
STEP TWO:
Download Busybox from here : http://rapidshare.com/files/407238531/busybox What is Busybox ?? Read about it here: http://www.busybox.net/
MD5 Signature: C5B76280434EEF49310AD8F1810B10B2
STEP THREE:
One you have downloaded busybox, copy it to the C:\ drive of your computer and then follow the next step. The next step is to open the Command Prompt ( type cmd in the Run prompt ) if using Vista right click on "Run as Administrator".
Assuming you are the root of C:\
Type: C:\cd android-sdk-windows
-> then
Type: C:\android-sdk-windows\ cd tools
-> if you have android debug shell and USB drivers properly installed
Type: adb devices
Now your device will show up as a binary number .. Success ! if it doesn't show up you need to install the drivers again or something else is wrong.
STEP FOUR:
Now once your device shows up, we will need to download the busybox from the computer to the phone. Since we can write anything in the /data/local portion of the android system we will copy the busybox file to the android device.
Type: adb push busybox /data/local/busybox
Once it has been copied to your device issue this command.
Type: adb shell This coomand is issued to go to your mobile's terminal where you can issue commands internally to the phone.
--> then
Type: cd /sdcard This command is given inorder to go to the sdcard ( i.e the internal storage of your phone )
--> then
Type: chmod 755 /data/local/busybox This command is issued to set user -rwxrwxr-x permissions to the file.
--> then
Finally, issue this command.
Type: /data/local/busybox tar cvf Samsung.tar /system This command is given to copy and tar the system folder where all the stock applications and programs are and to create a dump of that system folder.
STEP FIVE:
Job Done !!
The Samsung.tar file can be copied to the computer now. Have fun.
this is perfect, as i want to create a dump of my original ROM
A dump is simply a backup of your original ROM right?
thats good news if it is indeed a a backup of the stock firmware.
i want to back up my warranty firmware!

it is only a backup of your stock apps and driver if so however it doesnt convert the files into a flashable rom version.
is there a way for us to backup the firmware?? (not just stock apps)

So this is not a tutorial of how you back up your stock rom but how you back up your stock apps and stock drivers?

Correct. We most likely won't be able to actually perform a complete backup until Nandroid works on the handset.
Too bad, the title was very promising but what you show is just an backup archive of the system.
BTW, there is no guarantee that restoring it will produce a usable phone, because kernel, datas, modem baseband etc won't be restored too !
But this can be useful to restore some file after a mistake done on /system files.

im working on creating a stock rom ... may be some happy results and happy faces. who knows . keep sticked !
uploading dump again .. please wait.
So, Can i just select this dump in Odin and it will recover to stock firmware. Quite confused here.
The file size is 275 megs , so is it only for apps? Have you flashed with this dump. Nice work so far. THanks.
Edit: Just realised the dump option in Odin is for dumping my rom , not loading one.
So stuck with this until Samsung update. Huh!
Is this the same procedure as making a backup /efs?
I've been searching the forum for hours and this is the only thing I could find that looked anything like it.
This won't work
No, no and no !!
This procedure will not backup your stock ROM.
A complete rom consists in:
- a primary bootloader.
- a secondary bootloader.
- an initrd image with the kernel.
- a rootfs (the /system partition).
- an efs partition.
- a binary radio firmware.
There is no known method to backup all the flash partitions and transform them into proper files that can be reflashed with Odin or Heimdall.

+1.. The thread is misleading.. This doesn't accomplish anything! You really think people in the "Android Development" section don't know about tar?
Did anyone already managed to get the built-in dump function from Odin working?
With Odin v1.3 there was the possibility to decide whether to dump AP RAM or AP NAND (followed by an ID).
With Odin v1.52 you can't choose this anymore. It will only dump AP NAND.
But my first attempts were unfortunately not very promising
Howdy all,
Just wondering, how are the system.img files made? I have read that if it's a YAFFS image file, that the maximum filesize cannot exceed 128MB. However, I've seen on some NAND HD2 Android builds, the system.img filesize is >128MB.
My question is, what method are you guys using for making the NAND system.img files to flash within MAGLDR? (ie. is it like a ZIP archive with a .img extension on it)
I'm currently working on a remix of a ROM that I use (a hint is in my Sig), and I know that the update.zip method that was used on "true-Android" devices to change ROMs doesn't apply to our MAGLDR method now.
Cheers and I'm sure you'll see another ROM for the HD2 in the coming weeks!

The system.img is a yaffs2image. Google 'compiled windows unyaffs' use that program to take a peak inside the .img. When you're completely ready to make your own .img your gonna need a linux distro or cygwin w/mkyaff2image compiled. However I recomend compiling the mkfs.yaffs2 command if you are using linux. Alternatively you can place the /system/ directory you are trying to make an image on your SD and run that command in the terminal emulator in Android. It should look like this #mkyaffs2image /sdcard/system/ System.img
Hope that helps.

Does this give you write abilities so that files can be changed out pre-flash?

I think you have to dump them to a folder, then you can change what you want. Then do the yaffs2 cmd and it will package it back up to .img for flashing...

I think that a tutorial is in order. Someone who knows how to extract and replace files in a system.img needs to write a short tutorial on how to do it. - A simple step by step on how to decompile a system.img and re-compile it.
I for one would be extremely grateful because I finally worked out a perfect MMS patch and I'd like to be able to easily modify the builds pre-flash.

I have been trying to do that all night. I can unpack them but haven't got around to repacking them. For now all I do is install the build and push the patched file that I have and do a AD hardrest in MAGLDR. MMS 300-1024k and all TMO US app works.

That's not actually a Gingerbread build - it's just themed to look like one, but still got the same name

Another option is to connect to ADB or Android Commander before going through the initial setup(when it asks you to choose your language) and change the files then - use the PC to reboot the phone, not the phone's built-in reboot. This should take you right back to the setup screen where this time, should show United States localization.
Still a bit too much work. I'd like to be able to patch the build, flash it, and be good to go.
found this but too educated for me

Windows
-----------------------------------------------------------------------------
Ok, let's start again. If you are using windows, google the said phrase above and you will find the precompiled utility 'unyaffs'.
Place the System.img you want to extract in a new directory with unyaffs.exe & drag the .img onto unyaffs. A command window will open and start extracting the files in the image to that same folder. You can now explore & edit/pull whatever you need to get things going. Once you have it the way you want copt it to your SD/root/ & make a folder for it with an obvious name like "Project" or "Test". Now to get it back into a bootable .img open Terminal Emulator in Android & enter the following
#mkyaffs2image /sdcard/NAMEofFOLDERuCHOSE/ System.img
**alternatively you can do this in windows itself if u have the utility compiled under cygwin or simular.
Linux
-----------------------------------------------------------------------------
Ok, you will need the unyaffs & mkfs.yaffs2 utilities compiled and working 1st off.
mkyaffs2image works to make the image however it fails upon flash with DFT Android Flasher. So I recomend mkfs.yaffs2 & have included it, you will need to place it in /usr/sbin/. If you have trouble copying it open a terminal and run "gksudo nautilus" then copy to the above mentioned directory.
**Now that those utilities are working let's get to work.
open a terminal and run 'unyaffs /home/yourusername/Desktop/targetdirectory/targetimage.img
copy/edit/pull the files you want. When your ready to build the image you are happy with open a terminal and run 'mkfs.yaffs2 /home/yourusername/Desktop/targetdirectory/ System.img'
Now your ready to flash !
System.img & Boot.img Contents
============================================================
System.img contains the entire root/system/ directory in Android
System/
app
bin
etc
fonts
framework
lib
lost+found
media
usr
xbin
build.prop
dmesg.txt
Boot.img contains
Boot/
initrd.gz
zImage
lost+found
============================================================
Hope that helps guys, It's my first tut on XDA
**EDIT: I included an archive for windows users that has unyaffs2.exe & cygwin1.dll
The Linux archive contains mkfs.yaffs2.x86, once moved to /usr/sbin/ rename to mkfs.yaffs2
The process works exactly the same for Boot.img
you need linux and run command by terminal
put them in /bin
http://www23.zippyshare.com/v/13814384/file.html
then you can yaffs or unyaffs
example
unyaffs /home/rafpigna/folder_with_img_you_wann_unpack/system.img
or
mkyaffs2image /home/rafpigna/folder_with_stuff_you_wanna_pack/ system.img
strange thing...when I open with unyaffs and then close with mkfs.yaffs2 or mkyaffs2image I get init: untracked pid 250 exited (where 250 varies) in a loop :S
some light for me?

linux x64.
btw no I didn't, because I want to make a rom (I'm not new to android development but that makes me think that I'm probably stupid )
Everything I do doesn't work.
Already tried something like:
- opened a premade working rom, exchanged just app and framework: no way
- exchanged everything but not bin/xbin/lib: no way
- exchanged just what was different between a stock and a premade leo rom: still no way
mmmh...
yaffs2
There is actually a way to modify files in a yaffs2 image but I've not done it my self yet. I'm 100% sure it's possible cuz everything is possible.... under Linux of course.
You need:
Linux, compiling skills, mounting skills, etc.
Basically for any other filesystems you can mount them as loop devices but not yaffs2. For yaffs2 you actually need a virtual mtd block device. once you have the mtd device you can mount the yaffs image on it.
For details google for: mounting yaffs image
and focus on virtual mtd block device.

This has a list of files to be pulled. Hope this helps. BTW michy I need help with a kernel, know anyone?
I'm Having a problem using on Linix, when i use the unyaffs trough the terminal it extracts the rom but not the squashed contents, which in the main apps and frame work are at on thoughs roms. I do get a file that says squashed but empty. I tried on cyanogens 6.1 rom and everything extracted fine.but that rom does not have a squashed folder, am i doing something wrong?
1. If i unyaffs System.img and manually remove some programs/aplications then create System.img with yaffs, does it programs will appear in apps and does my rom will be caused a more memory for other programs for installation?
2. Is it possible to unyaffs Boot.img then replace zimage with newest kernel like MDJ or hastarin then yaffs to new Boot.img, After that i suppose then this Android OS will be on new kernel???
3. And... If i remove zimage and initrd.gz from Boot.img, create new Boot.img without these two files and these two files copy to SD card and define that two files in flash.cfg for find on SD. Does it works?
Sorry for bad English.
Good morning family!
It's my very first time posting in this subforum, but I think this tutorial was actually something needed, since all threads everyone can found while Googling are quite old (like, from the Xperia S times ), and also I'm quite tired of infinite threads like this and this, so...
Today I bring you an extensive and unified guide on how to extract ANY SYSTEM FILE from a FlashTool's Firmware (FTF), whether it's from the userdata.sin or from the system.sin.
Since this is going to be a guide for all OSes, there are some programs you'll need in general,
Latest version available of FlashTools (for SIN dumping purposes).
A reader tool for the extracted image, which can be:
An EXT4 reader / mounter.
An Unyaffs2, if you're using this guide for an old device (like the already mentioned Xperia S, and older).
Some cups of coffee, and lots of patience [IMPORTANT].
But, some of them will be platform specific, so the thread will split in:
2nd post: WINDOWS
3rd post: LINUX
4th post: OSX
Here you've a video tutorial showing the whole process for the 3 OSes:
If you're enjoying it, don't forget to press Thanks button and rate this thread!
WINDOWS GUIDE
Step 1 - Extract the SIN we need
Using your favourite archive manager (WinRAR, 7-Zip, etc), open the FTF you want to extract the files from. (FYI: an FTF is just a Zip file with renamed extension)
Now copy/extract the SIN you want to unpack to a folder of your preference.
Step 2 - Dump the SIN
I'll take into account you already had installed Flashtools and Java JRE, in which case I highly encourage you to update both to the latest version available.
Now, open Flashtools. Click on Tools, Sin Editor. Hit the [...] and locate the SIN you previously extracted. Now, hit the [Extract Data] button. After a couple of minutes the bar should start running.
Once finished, you can have 2 kind of files: a .yaffs2 or a .ext4/.ext3/.ext2 file, which require different procedures on how to see it's contents.
Step 3.a - Convert the file to a readable format - UnYaffs2
If the file you get is a .yaffs2 format file, you're going to need to extract it. For doing so, you need this tool, which contains a executable and a cygwin dll.
Extract this .rar contents to the very same folder where you placed the SIN, and thus, where the .yaffs2 is located.
Now, while you're in that folder press the shift key in your keyboard, and while you keep pressing it, right click on a blank space in that folder. In the menu choose Open a Command Prompt here.
To end the proccess, type
Code:
unyaffs2.exe [COLOR="DarkOrchid"]<the-name-of-the-yaffs2>[/COLOR]
Where <the-name-of-the-yaffs2> you must type the file name of the yaffs2 (e.g. system.yaffs2)
The files will get extracted and you'll be able to pick the ones you need.
Step 3.b - Mount the image - Linux Reader
There're many many tools to mount a EXT format image in Windows, but in this case, I'll use the Diskinternals Linux Reader, since it's free and it's compatible with all 3 possible formats you can encounter: .ext4/.ext3/.ext2.
Download it from here and install it. (It must be this version, since newer ones are broken.)
Once done, you should be perfectly able to double-click-to-mount the EXT file Flashtools generated without any trouble.
LINUX GUIDE
Step 1 - Extract the SIN we need
Using your favourite archive manager (Ark, Peazip, etc), open the FTF you want to extract the files from. (FYI: an FTF is just a Zip file with renamed extension)
Now copy/extract the SIN you want to unpack to a folder of your preference.
Step 2 - Dump the SIN
I'll take into account you already had installed Flashtools and Java JRE, in which case I highly encourage you to update both to the latest version available.
Now, open Flashtools. Click on Tools, Sin Editor. Hit the [...] and locate the SIN you previously extracted. Now, hit the [Extract Data] button. After a couple of minutes the bar should start running.
Once finished, you can have 2 kind of files: a .yaffs2 or a .ext4/.ext3/.ext2 file, which require different procedures on how to see it's contents.
Step 3.a - Convert the file to a readable format - UnYaffs2
If the file you get is a .yaffs2 format file, you're going to need an extra tool to extract it. For doing so, you are going to need the unyaffs2 tool.
You can download a pre-compiled binary from here, or you can compile your own using GCC with the source code, the header and the code below inside a Terminal (Ctrl+Alt+T to open it).
Code:
gcc -o unyaffs unyaffs.c
Once you've a working UnYaffs2 binary, just copy it to the very same folder where you placed the SIN, and thus, where the .yaffs2 is located, and type in a Terminal (Ctrl+Alt+T to open it).
Code:
cd [COLOR="DarkOrchid"]<file-route-of-the-sin>[/COLOR]
./unyaffs2 [COLOR="Blue"]<the-name-of-the-yaffs2>[/COLOR]
Where <file-route-of-the-sin> is where the SIN was located, and where <the-name-of-the-yaffs2> you must type the file name of the yaffs2 (e.g. system.yaffs2)
The files will get extracted and you'll be able to pick the ones you need.
Step 3.b - Mount the image
Since we're already in Linux, mounting a EXT image is not that hard. Just mount it using this commands in a Terminal (Ctrl+Alt+T to open it).
Code:
cd [COLOR="DarkOrchid"]<file-route-of-the-sin>[/COLOR]
mkdir android
sudo mount -t ext[color="RED"]*[/color] -o loop <name-of-the-image> android/
Where <file-route-of-the-sin> is where the SIN was located, where <the-name-of-the-image> you must type the file name of the ext image (e.g. system.ext4), and finally, where ext*, replace * with the version number of the EXT image you're mounting, usually, ext4
Now, once finished, to unmount it, type in a Terminal.
Code:
sudo umount android
rm -fr android
OSX GUIDE
Step 1 - Extract the SIN we need
Using your favourite archive manager (UnRarX, ZipEg, etc), open the FTF you want to extract the files from. (FYI: an FTF is just a Zip file with renamed extension)
Now copy/extract the SIN you want to unpack to a folder of your preference.
Step 2 - Dump the SIN
I'll take into account you already had installed Flashtools and Java JRE, in which case I highly encourage you to update both to the latest version available.
Now, open Flashtools. Click on Tools, Sin Editor. Hit the [...] and locate the SIN you previously extracted. Now, hit the [Extract Data] button. After a couple of minutes the bar should start running.
Once finished, you can have 2 kind of files: a .yaffs2 or a .ext4/.ext3/.ext2 file, which require different procedures on how to see it's contents.
Step 3.a - Convert the file to a readable format - UnYaffs2
If the file you get is a .yaffs2 format file, you're going to need an extra tool to extract it. For doing so, you are going to need the unyaffs2 tool.
You can download a pre-compiled binary from here, or you can install your own using Brew. From a Terminal (Command+Space, then type in Terminal) type the following commands.
Code:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null 2> /dev/null #This is just to Install Brew for the first time. If you already have it, it's not needed.
brew install unyaffs
If you chose using the UnYaffs2 binary, copy it to the very same folder where you placed the SIN, and thus, where the .yaffs2 is located.
If you chose the Brew installation, just continue.
Now, type in a Terminal (Command+Space, then type in Terminal).
Code:
cd [COLOR="DarkOrchid"]<file-route-of-the-sin>[/COLOR]
unyaffs2 [COLOR="Blue"]<the-name-of-the-yaffs2>[/COLOR]
Where <file-route-of-the-sin> is where the SIN was located, and thus, where the yaffs2 file is located; and where <the-name-of-the-yaffs2> you must type the file name of the yaffs2 (e.g. system.yaffs2)
The files will get extracted and you'll be able to pick the ones you need.
Step 3.b - Mount the image - Ext4FUSE
There're many many tools to mount a EXT format image in OSX, but in this case, since we don't need RW access, but just RO, I'll use ext4fuse, since it's free and it's more than compatible with our needs.
To install it you'll need Brew. To get things ready, type the following commands in a Terminal (Command+Space, then type in Terminal).
Code:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null 2> /dev/null #This is just to Install Brew for the first time. If you already have it, it's not needed.
brew tap homebrew/fuse
brew install Caskroom/cask/osxfuse
brew install ext4fuse
If you're on OSX Yosemite, El Capitan, or Leopard, you may need an extra command to add yourself to the Operator group, so that you can have readonly permissions to the disks.
Use it only if you get an error while trying to access the mounted EXT image later.
Code:
sudo dscl . append /Groups/operator GroupMembership [COLOR="red"]<your-user>[/COLOR]
Where your user <your-user> is your username.
Now, to mount the ext4 image, type in a Terminal (Command+Space, then type in Terminal).
Code:
mkdir android
ext4fuse [COLOR="DarkOrchid"]<path-to-the-ext4-image>[/COLOR] android
Where <path-to-the-ext4-image> you must type in the full path where the SIN was located, and thus, where the EXT4 image is located.
Use this as reference.

Great job! Keep up the good work!!
Well. great guide.
Just a note, Microsoft officially released Bash on Ubuntu on Windows yesterday. Try it. It's a full fledged Linux subsystem but unfortunately only available to Windows Insiders. It would be the best alternate to cygwin.
Boot.img
How can i extract the boot.img
or is this applicable to every single .sin file present in the .ftf file

I know, I saw the demonstration in the //build/, but since it hasn't been released for all yet (I guess it'll be for Redstone 2?), I didn't saw it necessary to be included.

or is this applicable to every single .sin file present in the .ftf file
Click to expand...
Click to collapse
No, this is only applicable for system.sin, userdata.sin, cache.sin and probably modem.sin.
However, if many of you request it, I could try making another for the kernel (boot.img)... But remember, every device doesn't have the same way/method to unpack the kernel, so making a generic tutorial for all wouldn't be possible

This thread got featured in XDA Portal, thank you guys!
I tried extracting Xperia Pro's system SIN (can't remember the exact name but the one with the largest file size) using the latest version of Flashtool but wasn't successful. Like it's not supported yet.
So there's threads about how to unpack UPDATE.APP on windows/PC/OS X so i decided why not do it on android too, this apps requires some additional tools to be downloaded just as OS X/Windows and linux needs as well. but process is otherwise similar. this tutorial doesn't need root!
NOTE THIS TUTORIAL isn't fully working on OREO on Huawei devices, it has some issues and i haven't found a workaround for it yet!
Needed apps

@Atarii 's modification of splitupdate to manually enter the partitions you want to unpack
The desired FW you wan't to unpack
Unpack process:
Download Termux
Open termux and type
termux-setup-storage This will allow termux to access your /sdcard
pkg install perl (this will install perl which the update.app process is using) once asked press y and enter.
copy the downloaded files to root of your SDCARD *We keep this simple*
Once copied type: cd storage
perl splitupdate UPDATE.APP partitionyouwanttoextract if everything goes well you should be good to go and having the selected files in a folder called output where selected files should be stored.
The unpack tutorial is done. But wait! If you want to browse the files you need to do one more thing or two.
Download android image kitchen

This will allow you to *unpack boot/recovery and convert system image (also vendor, product, cust and version)
*in order to unpack a boot or recovery file you'll need to remove all code using a hex edit file until you see ANDROID text. Else it won't unpack. You can unpack aosp images easily with this tool and modify what you want and repack to flash it on your device tested with twrp image for honor 8.
I would suggest to not unpack/repack boot using this tool since it'll cause problem.
There's a python script that works to unpack boot and recovery which can be found https://github.com/liudongmiao/bootimg/blob/master/bootimg.py
For this you'll need to install python.
pkg install python and hit y and enter
Now you just do as the splitupdate part where you extract the file.
Command to unpack
python bootimg.py --unpack-bootimg similar is for ramdisk but you replace bootimg with ramdisk.
To repack just simply python bootimg.py --repack-bootimg
Please note if you repack ramdisk the boot might not work (it's a while since I tested this) now this covers up how you unpack boot and extract update.app from phone.

Known Issues:
If you get Killed when trying to extract system.img this is most likely because the image size is too big, this isn't due to small space available i guess its due to all ram is being taken yet i can't tell.
i get permission issues. yeah this can happen sometimes try chmod +x or chmod 0777 with root, it might help.
when typing termux-setup-storage i get lots of errors and i'm on 8.0 EMUI
This is not your fault it's a bug caused by android i'd guess, or app isn't adopted completely for 8.0

What is the easiest way (using a graphical tool or command line on Ubuntu Linux) to know if two binary files are the same or not (except for the timestamps)? I do not need to actually extract the difference. I just need to know whether they are the same or not.
