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.

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.

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?

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.
This is how I made ROM, I'll try to write the steps as simple as I can. For advanced users only!
Update 22/08/11:
Revised packaging steps.
Update 13/08/11:
Removed unwanted method for ROM cooking.
Update 04/08/11:
Modified extract and repack ROM guide and added extracting system.rfs guide.
Things you need:
Base firmware
Archiver software (7zip recommended)
Any Linux environment to build ROM or Cygwin
APK Manager to optimize and decompile *.apk files
MagicISO (Optional) if you want to extract system.rfs
And the last thing is... You need enough experience in android world
So, here is the steps to cook a ROM:
Flash your phone with your desired base firmware
Make required modifications
Pull system.rfs from your phone by running this command on adb shell or Terminal Emulator:
Code:
dd if=/dev/stl12 of=/sdcard/system.rfs
Extract any *.tar.md5 files from your base firmware to your working folder with 7zip
Replace the current system.rfs with your modified one
EDIT: Pack your ROM by running this code via terminal or just pack it with 7zip/WinRAR as *.tar
Code:
tar -H ustar -c * >> ROMNAME.tar
change ROMNAME to your desired, well, ROM name.
Here is (yet) useful guide to modify your ROM.
Extract system files on system.rfs to make modding easier:
Extract PDA file (*.tar.md5) files with 7zip
Open system.rfs with MagicISO
To extract it, just drag and drop
NOTE: Never edit your ROM with MagicISO because the file permissions will be ignored, use MagicISO only for extracting files from system.rfs
Deodex, and Zipalign (optimize) your ROM apk files:
Ready to use deodex + root for KPN: http://forum.xda-developers.com/showthread.php?t=1196230
Ready to use deodex + root for KPH and other firmware: http://forum.xda-developers.com/showthread.php?t=1118048
Open APK Manager
To zipalign your apk files, in apk manager folder /place-apk-here-to-batch-optimize put your:
framework-res.apk, twframework-res.apk and all system apk
but not these:
AxT9IME, Calculator, Camera, Email, MMS, Phone, Screen Capture, Settings, Swype, Thinkdroid, Voice search
Choose Choose option 15
Then choose both (zp)
Let it run and done.
Now put back the apk files where they belong in the ROM.
How to put these apk files to my ROM? Copy these files to appropriate locations, such as /system/app to your ROM's /system/app, and etc.

As Linux, MagicISO read RFS image as a FAT filesystem. File permissions can not be maintained. A better way but need linux:
1. Mount system.rfs as FAT and mount it to /tmp/rfs
2. Make ext4 image, and mount it to /tmp/system
3. Copy /tmp/rfs contents to /tmp/system
4. Make modification inside /tmp/system
5. Fix file permissions inside /tmp/system
6. Umount both image
7. Make ODIN flashable image, contains system.rfs (now in ext4 format) and CF-Root-S5830 boot and recovery image (for ext4 support)
8. Boot to Windows and flash your new firmware using ODIN.

Please take look at the first page, it's updated, you know?
After I created md5 file and selected it in odin, it says "invalid image type" and "invalid model binary". How to solve that? After that I continued, skipped these errors and flashed, my phone stopped at boot screen with text "Galaxy ACE....". Plz help me
Overview:
This thread is a guide on how to fix the apply_patch_check error message experienced during an upgrade of the Android OS. Specifically, this will detail the steps for an upgrade of Jelly Bean from 4.1.1 to 4.1.2 on the Nexus 7 with CWM Recovery for a user of Windows. I'm sure similar steps will work for other recoveries/upgrades/devices and PC OSes.
You should only bother with this if you don't want to flash the entire system.img file to your phone, which is way easier.
Here is an example of the error message I'm talking about:
Code:
assert failed: apply_patch_check("/system/app/Chrome.apk", "819b34b66335c6faec86404d736a002b8871600", "9d6b55e63b0bf20bea433fb1ee7089f88ab73fb6")
E: Error in /sdcard/03a4eaf95f73.signed-nakasi-JZO54K-from-JRO03D.03a4eaf9.zip
(Status 7)
Installation aborted.
A few notes about the error:
This doesn't have to happen with the Chrome.apk specifically -- it could happen with any app in /system/app or .so in /system/lib.
Those random strings of numbers/letters are SHA-1 hashes of the apk.
The first one is the hash of the apk installed on your device. In my example, this happens to be the version of Chrome that comes with JB 4.1.2.
The second one is the expected hash of the apk that comes with JB 4.1.1.
Cause of the problem:
The reason this error occurs is because the file was somehow modified from its original state. In my case -- and most likely your case -- this was done by Titanium Backup. TB has an option to "Integrate updates of system apps into ROM", which will cause the apk in /system/app (and associated library files in /system/lib, if needed) to be overwritten with the updated apk.
Solution:
Download this zip file which contains the full /system/app and /system/lib directory from the JB 4.1.1 factory image. *
Extract the zip to a location of your choosing on your PC.
In the extracted folder, locate the .apk or .so file referenced in the error message on your device.
Copy this file to your device via your preferred method (USB cable works fine). I put my file in /sdcard/Download.
On your device, use a root file explorer to move the file from /sdcard/Download to /system/app (or /system/lib).
If you don't have a program that can do this, I use ES File Explorer. Be sure to go to Settings > Root Settings and turn on Root Explorer, Up to Root, and Mount File System.
Reboot into your Recovery and try to install the update again.
Repeat steps 3-6 for each subsequent file that produces an error. You will basically need to do this for each app you integrated using TB and maybe a few library files, too. **
* Future updates (above 4.1.2):
Since I won't be keeping the zip file from step #1 up-to-date, here's how to get the directories that I included in the zip for yourself:
Obtain a factory image for your device's current Android version (the version you're updating from).
For JB 4.1.1, this file is called nakasi-jro03d-factory-e102ba72.tgz.
If you're reading this guide at a later date, the JB 4.1.2 file is called nakasi-jzo54k-factory-973f190e.tgz.
You can try your luck at the official Google site, but they seem to only provide the version you're trying to update to, not from.
Extract the .tgz file somewhere on your PC.
Locate the image-naksi-jro03d.zip file and extract that, as well.
In the folder you just extracted from the previous step, located the system.img file.
Download and use a program called sgs2toext4 (View attachment 645320) to convert the system.img to system.ext4.img. ***
Download and use a program called Linux Reader to open system.ext4.img.
Do this by going to Drives > Mount Image > Next > select your file.
It will then be listed under the Hard Disk Drives section in red as "Linux Ext Volume 1".
Navigate to: Linux Ext Volume 1/system.
Right-click on the app (or lib) directory and pick Save > Next > Output to dir of your choice.
You now have the directories that were included with the zip file from Solution step #1, so just follow those steps now.
** How to avoid repeating steps:
If you'd rather not have to try to reinstall after updating only one file, just to find another file that needs updating, try this:
Obtain the /system/app and /system/lib folders from the factory image and save them to your PC.
For the sake of this guide, let's say you save them to C:\factory_app and C:\factory_lib.
Copy the /system/app and /system/lib directories from your phone to your PC.
For the sake of this guide, let's say you saved them to C:\phone_app and C:\phone_lib.
Download the File Checksum Integrity Verifier utility from Microsoft.
Start > Run > cmd
fciv.exe -sha1 -xml factory_app.xml -wp C:\factory_app
fciv.exe -sha1 -xml factory_app.xml -v -bp C:\phone_app
Don't ask me why, but you need to use -bp instead of -wp for the second command.
Don't forget the -v on the second command.
The output of the last command will show you the list of files that are different. These are the files you need to take from C:\factory_app and put into the /system/app directory on your phone.
Do the same for the lib directories (just replace all instances of "_app" with "_lib" in the previous commands).
Summary:
I hope that this post helped some of you who really didn't want to have to flash the system.img or wipe your device just to update. In the future, use TB to back up the original.
I wouldn't normally bother writing up a guide like this (it took almost as long to write as it did to figure out how to do this) but I couldn't find this solution anywhere even though I saw that I wasn't the only person with the problem. Sorry for not posting this guide sooner (update has been out for a while now), but the forum required me to make a bunch of useless spam posts before I could include any links in my guide and I didn't get around to making those posts right away.
*** I would like to thank balamu96m for his guide on extracting data from the system.img file and drphrozen for making the sgs2toext4 program.
Thanks for this. Will try now.
Worked great. Had to copy the apk and odex file.
Good job! It's great to see the steps for Windows users!
Just a heads up that I simply extracted the files I needed from and on my N7 using Root Explorer, without using my PC at all.
Great guide! Method worked perfectly on my Nexus 7 going from 4.1.2 to 4.2, thanks
Please... is there some other way to update the files w/o installing Java on my Windoze PeeCee? I accidentally messed up my YouTube.apk with Titanium Backup... now I can't update from 4.1.2 --> 4.2 JB.
EDIT: JavaPortable FTW... updating (fingers crossed)
EDIT: SUCCESS TY OP!
For anyone who flashed the 4.2 clock/keyboard already
Hey, for anyone who flashed the 4.2 clock and keyboard on their Nexus 7 already and need to roll back to do the 4.2 update, I used OP's method to make a flashable zip that puts the 4.1.2 clock and keyboard back.
Worked perfectly for my Nexus 7 to get me up and running. Hope it helps anyone!

I don't have a Galazy Nexus, but I think the steps should be the same. Here is a link to the factory images: https://developers.google.com/android/nexus/images#takju . It looks like they now have links for older versions, rather than just the newest images (which is how it was when I made my guide). So that's pretty sweet.
Thanks a lot man, i succeeded to "patch" my system files to update from 4.2 to 4.2.1. I first check what files didn't correspond with fciv (9 files counting both apks and odex) and then replaced them in system/app. In fact they were the apps I previously integrated with tb (learned lesson: never do it if you want to remain stock and receive OTAs). I also noticed many not-matching files in system/lib but i didn't touch them and the update went smooth the same.
Another thing: when in the OP you say it's way easier just to reflash the system.img you mean just run from bootloader "fastboot flash system system.img" (taken from the factory image as usual) or there's some other thing to do in order to fix the system partition in the right way?

Thank you very much.

Overview:
This thread is a guide on how to fix the apply_patch_check error message experienced during an upgrade of the Android OS. Specifically, this will detail the steps for an upgrade of Jelly Bean from 4.1.1 to 4.1.2 on the Nexus 7 with CWM Recovery for a user of Windows. I'm sure similar steps will work for other recoveries/upgrades/devices and PC OSes.
You should only bother with this if you don't want to flash the entire system.img file to your phone, which is way easier.
Here is an example of the error message I'm talking about:
Code:
assert failed: apply_patch_check("/system/app/Chrome.apk", "819b34b66335c6faec86404d736a002b8871600", "9d6b55e63b0bf20bea433fb1ee7089f88ab73fb6")
E: Error in /sdcard/03a4eaf95f73.signed-nakasi-JZO54K-from-JRO03D.03a4eaf9.zip
(Status 7)
Installation aborted.
A few notes about the error:
This doesn't have to happen with the Chrome.apk specifically -- it could happen with any app in /system/app or .so in /system/lib.
Those random strings of numbers/letters are SHA-1 hashes of the apk.
The first one is the hash of the apk installed on your device. In my example, this happens to be the version of Chrome that comes with JB 4.1.2.
The second one is the expected hash of the apk that comes with JB 4.1.1.
Cause of the problem:
The reason this error occurs is because the file was somehow modified from its original state. In my case -- and most likely your case -- this was done by Titanium Backup. TB has an option to "Integrate updates of system apps into ROM", which will cause the apk in /system/app (and associated library files in /system/lib, if needed) to be overwritten with the updated apk.
Solution:
Download this zip file which contains the full /system/app and /system/lib directory from the JB 4.1.1 factory image. *
Extract the zip to a location of your choosing on your PC.
In the extracted folder, locate the .apk or .so file referenced in the error message on your device.
Copy this file to your device via your preferred method (USB cable works fine). I put my file in /sdcard/Download.
On your device, use a root file explorer to move the file from /sdcard/Download to /system/app (or /system/lib).
If you don't have a program that can do this, I use ES File Explorer. Be sure to go to Settings > Root Settings and turn on Root Explorer, Up to Root, and Mount File System.
Reboot into your Recovery and try to install the update again.
Repeat steps 3-6 for each subsequent file that produces an error. You will basically need to do this for each app you integrated using TB and maybe a few library files, too. **
* Future updates (above 4.1.2):
Since I won't be keeping the zip file from step #1 up-to-date, here's how to get the directories that I included in the zip for yourself:
Obtain a factory image for your device's current Android version (the version you're updating from).
For JB 4.1.1, this file is called nakasi-jro03d-factory-e102ba72.tgz.
If you're reading this guide at a later date, the JB 4.1.2 file is called nakasi-jzo54k-factory-973f190e.tgz.
You can try your luck at the official Google site, but they seem to only provide the version you're trying to update to, not from.
Extract the .tgz file somewhere on your PC.
Locate the image-naksi-jro03d.zip file and extract that, as well.
In the folder you just extracted from the previous step, located the system.img file.
Download and use a program called sgs2toext4 (View attachment 645320) to convert the system.img to system.ext4.img. ***
Download and use a program called Linux Reader to open system.ext4.img.
Do this by going to Drives > Mount Image > Next > select your file.
It will then be listed under the Hard Disk Drives section in red as "Linux Ext Volume 1".
Navigate to: Linux Ext Volume 1/system.
Right-click on the app (or lib) directory and pick Save > Next > Output to dir of your choice.
You now have the directories that were included with the zip file from Solution step #1, so just follow those steps now.
** How to avoid repeating steps:
If you'd rather not have to try to reinstall after updating only one file, just to find another file that needs updating, try this:
Obtain the /system/app and /system/lib folders from the factory image and save them to your PC.
For the sake of this guide, let's say you save them to C:\factory_app and C:\factory_lib.
Copy the /system/app and /system/lib directories from your phone to your PC.
For the sake of this guide, let's say you saved them to C:\phone_app and C:\phone_lib.
Download the File Checksum Integrity Verifier utility from Microsoft.
Start > Run > cmd
fciv.exe -sha1 -xml factory_app.xml -wp C:\factory_app
fciv.exe -sha1 -xml factory_app.xml -v -bp C:\phone_app
Don't ask me why, but you need to use -bp instead of -wp for the second command.
Don't forget the -v on the second command.
The output of the last command will show you the list of files that are different. These are the files you need to take from C:\factory_app and put into the /system/app directory on your phone.
Do the same for the lib directories (just replace all instances of "_app" with "_lib" in the previous commands).
Summary:
I hope that this post helped some of you who really didn't want to have to flash the system.img or wipe your device just to update. In the future, use TB to back up the original.
I wouldn't normally bother writing up a guide like this (it took almost as long to write as it did to figure out how to do this) but I couldn't find this solution anywhere even though I saw that I wasn't the only person with the problem. Sorry for not posting this guide sooner (update has been out for a while now), but the forum required me to make a bunch of useless spam posts before I could include any links in my guide and I didn't get around to making those posts right away.
*** I would like to thank balamu96m for his guide on extracting data from the system.img file and drphrozen for making the sgs2toext4 program.

my error 7 was generated by emmc: dev/block/mmdblk0p7 (the file is "param" any suggestions?
Thanks. After searching for a lot of time, this post helped me updating my SGS3.:victory: I previously tried to integrate youtube update into rom using titanium backup.

Another thing: when in the OP you say it's way easier just to reflash the system.img you mean just run from bootloader "fastboot flash system system.img" (taken from the factory image as usual)

Yes, that's what I mean. The reason I didn't want to do this on my device is because I had modified some other system files that I wanted to keep the modifications for.
Wow, thanks a lot OP! Your guide helped me fixing an error during the update to 4.2.2 on my Nexus 4.
please include a video ,im getting lost in the details
solved.
I have a complete setup for the Nexus 7, part of a product we are working on, that I need to easily clone on "virgin" tablets for production. The app requires a rooted OS.
I want to write an installation script using fastboot to unlock the bootloader, erase partitions, then flash them with .img files for each partition (kernel, system, cache, etc.).
How do I extract .img files from my "master" tablet? I have an understanding from some where that these are simple byte-for-byte dumps of the partition -- is this true? As such can I create a .img file by simple doing 'cat blkfile >file.img' where "blkfile" is the appropriate block device for the partition in question?
Or do I need to use 'dd'? Or something else?
I have searched and searched, and can't find an anwer. I've found other answers using some tools to create these files from a build on a PC, but nothing about creating them from an existing tablet.
Thanks in advance!
Use the dd command. You can use it both to dump and write a partition. It's how I install recovery programs like TWRP
Sent from my Nexus 7
You can use dd for the boot partition and recovery partition - they are raw binary blobs. (Don't use dd on other Android devices, esp. those that have MTD flash devices, though - it only works most of the time there)
If you want to use the same fastboot-based scenario that Google uses for factory image sets, then for the system & userdata image files you will need to find out about "sparse ext4 filesystem images"
If you took a raw block-device based dump of any of your tablet ext4 partitions, you could actually take those image files and mount them on any other linux machine (using a loopback mount procedure).
But you will find that if you attempt to do that with the Google factory ".img" files (for system & userdata partitions), they will not mount. It's not a simple matter of a offset superblock, either.
Since these are the formats that the stock recovery expects, I suppose you ought to use those formats if you want to do the "all at once all partitions" fastboot flashing if you plan on using the stock recovery.
Note that there is absolutely nothing that prevents you from unpacking whatever you want from whatever archive format you want - so long as the recovery's busybox supports the archive format correctly - you could use cpio or pax or tar archives for that matter. (The stock recovery's "toolbox" has very little functionality, so this comment applies to custom recoveries, which typically have more robust functionality in their busybox) You will be writing your own scripts to do those things though, typically either in one of two ways:
1.A mount target filesystem partition
1.B do a deep recursive remove at that mountpoint ( rm -rf * )
1.C unpack your archive into same mount point ( tar xf archive.tar, etc)
1.D unmount the mount point
OR
2.A unmount target partition and zero it out (dd if=/dev/zero, flash_erase, etc)
2.B recreate filesystem in partition (mke2fs -t ext4 etc)
2.C mount target filesystem
2.D unpack your archive into the same mount point (tar xf archive, pax, cpio, unyaffs2, etc)
2.E unmount that mountpoint
Even though this post is for the Samsung Galaxy S II, the same thing applies to the factory Nexus 7 images from Google:
http://forum.xda-developers.com/showthread.php?t=1081239
As that thread mentions, the simg2img and mkuserimg.sh programs are part of the Android project.
Here's a Nexus 7 thread where the contributor built the tools for both x86 linux and arm linux
Finally, I should note that because /system is typically mounted read-only, imaging /system from the live OS is no big deal. Trying to do the same thing with /data is an extremely dopey idea, however. Accurate backups are rarely made from live read-write filesystems.
cheers
Thank you so much for all the great information! I hit thanks for both of you.
The link to the nexus 7 thread is what I need... This is for my company, and I need a simple cloning solution that can be performed by a non-technical assembly person. The fastboot install procedure is about as simple as it gets.
Thanks again!
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.

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.
