how to extract system.img? - General Questions and Answers

Before anyone retorts, yes i have been through the forums and googled it. Nothing has worked yet
Ok, so i got this tablet called the skypad alpha2. There is an update for ics for it but it is a. Img file that has to be installed through their program calledlivesuite. Since it is a. Img file i am assuming it is a full system image because when it is installed it completely wipes everything.
Anyway, i have tried converting it, extracting it with unyaffs and all that.
Is there an alternative to unyaffs for windows?

[help]anybody can tell me how to convert official ROM to update.zip

anybody can tell me how to convert official ROM to update.zip
I want to know how to make an official from the ROM can customize the ROM, instead of only at others do the update.zip in thickening delete...
First, you need to run the RUU.
Check in your system TEMP folder, and you should have an update.zip there.
Unzip that, and you'll have amongst others, system.img
Extract the files via unyaffs or other means, customize your build, zip and sign.
Voila.
My guess is that a simple search via the search tool would've resolved that, then again, I guess you were too lazy to do that.

http://code.google.com/p/unyaffs/downloads/list
made for linux, but if you know a bit of c, you can probably change it to work with windows, maybe I will do that if I have some time this week.
********OR********
http://jiggawatt.org/badc0de/android/unyaffs-x86-win.zip
or http://www.4shared.com/get/fgryPnPx/unyaffs-windows.html
for windows..... instructions below apply for both
if not included in the zips above, cygwin1.dll and unyaffs.exe are included as an attachment of this reply.
open up a command line, in windows vista/7 just press start and then type cmd press enter and change the directory to the folder with the unyaffs and the img in it. in xp press start>run>cmd... then the same
the usage is: unyaffs /path/to/img
example:
(if unyaffs.exe and system.img are both in c:\temp)
"c:\temp> unyaffs /temp/system.img"
note: the '/' is the way linux determines the pathname of a file and since it is built using cygwin(a file allowing for windows) it is preferrable that the path to the actual file is in unix POSIX format ie: / instead of \ between folders and files.
*********WARNING************
this will extract to directory that unyaffs binary is in.
That's so weird -- I was gonna post the same thing tonight. Thx for writing this up. It's odd that more people don't talk or ask about this tool!
I remember reading this stuff back when I got my G1, and tonight I was trolling the themes and apps section cause I couldnt sleep. (which I rarely look at)
I was baffled that this wasnt common knowledge. I figured if there was no threads about it that people just knew how and didnt have any problems with it. My mistake lol...
enjoy.
can you please explain what is it? what it does? thanks

Umm, it expands nandroid img files not sure how else to explain it. Clockworkmod backups are in the img file format. This process allows you to extract those files to get stuff out of them
Sent from my SPH-D700 using XDA App
When you create a backup in Clockwork recovery, it leaves you with a folder like this:
2010-11-18.08.52.49
As you can prob figure out, I made that backup on 11/18 at 8:52am
Inside that folder are .img files, such as: data.img and system.img
Those files basically contain your data (like apps you've installed from market) and system (..system apps that might've come with the phone).
In the orig post, he's explaining how to extract the files from these large .img files.
To give an example, I had a couple of corrupted clockwork backups, and wanted to ONLY pull out some database files (like text messages and call logs) which were not corrupted. Even tho the backup was messed up, I could still extract the files I needed by using the method above, then copied them manually to my phone.

Right, like if you wanted a file or a few files from clockworkmod img backup, then this process would give you an extended file system, other than what you would normally use to extract the img files. Just trying to understand this so, please correct me if im wrong.... I've been trying to get more knowledge of this, so im still learning.
I prolly sound like a complete idiot, lol...
Sweet! Thanks for this man. I'd been looking for how to do this for some time and kept ending up learning about emulation or some other tangential topic. This is the basic functionality I was looking for. Thanks for posting!
Np. I'm working on writing some stuff on top of the source code that should allow you to browse and pull just one our more file
Its been a but since I looked theory source code so it might take a while... Maybe in between semesters?

Dode you saved my as** thx big thx
Great, now how can I re-compress back to .img after I've made the changes that I want?
EDIT: Nevermind. I just made a zip of the new system folder and flashed it in CWM.
This worked great for me.
Thanks,
Bud
Man, I do not know how to thank you. I was able to recover some important stuff off of my cwm recovery backup. THANKS!!

[Q] Trying to update Xoom 4G, but I removed dungeondefenders.odex, I have system.img

I just can't find a way to extract what is in the .img files.
It's such a small file so shouldn't be hard to find.
Downloading it from the Play store does not resolve the issue
How can I re-acquire the needed .odex file and/or extract what I may need from the .img files?

Do you have a Backup of your system - if so restore your backup. If not google extract .img files and look for software.
No backup...I just need to find a way to extract the files from the .img files of which I did google but nothing useful came up

Why the hell is it impossible for someone to find a way to get such a small measly file to get this stupid update to go through!!
Which update are you trying to apply? You will need the pre-updated file. 4g updates were 3.2.4 and 3.2.6.

Make a nandroid backup of your current setup...restore stock, pull file, restore backup. Or try just opening the img file with winrar.

Because that's the first thing you do when you are going to flash stuff. If you had done this the first time you wouldn't be in this situation.

[Q] Is there any APK to exact the boot.img in the phone

I want to unpack the img but don't want to use in my pc(too confused).

I don't think there is. Maybe I'm wrong too.
Basically all these boot.img tools are written in shell/bash and is made specifically to run in Linux distros.
Anyways there is an Android app called, Complete Linux Installer that lets you install any Linux OS in your phone. But I doubt whether boot.img tools work, as it needs various library files for it to work.
On a side note, I guess it would be more complex to do it in phone rather than in PC, if there is some way for it to work.

Thank you for your reply, but do you feel strange that the IMG is created by the recovery, so it is rational that there is a tool about IMG building. then why there is no apk. I mean some professional can extract just from the CWM recovery, I think.
need root
if you wanna get boot.img i think you must be rooted.

yes, I root, so I can use the recovery to back and restore,
I think any app that can access zip files in the internal and external memory can extract boot.img.
Like ASTRO File Manager and stuff...
recovery?
You wanna install a rom?
or recovery??
or we speak about boot.img? (Boot img is the boot animation when you turn on your phone.)

Nooooo
boot.img is the kernel (zImage + Ramdisk packed into an image file) that lies in the /boot partition
@ OP - If you want to extract boot.img itself, there are various methods and from CWM recovery like you said. I thought you were mentioning about how to unpack the contents of the boot.img say like zImage, Ramdisk and other files.

It could be done using this post http://forum.xda-developers.com/showpost.php?p=20227868&postcount=1124 and a hex editor from play store on your phone. But would be even more fiddly than on pc I would imagine, unless your phone has a largish screen. It could be done though.
If editing the ramdisk, you would need to unpack and repack after editing, which usually requires linux. I recently found http://forum.xda-developers.com/showthread.php?t=2036528 for PC, but have not had a chance to try it yet, seems best solution for OP

1) "Stuck" is NOT a question. Please use descriptive thread titles
2) You haven't unzipped the image-hammerheadxxx.zip that contains the images :/
but I have I followed the instructions to a T and put all file in the folder under platform tools

Not sure what instructions you've followed. Either they're incomplete or you made a mistake. Like I said, your screenshot shows a zip file. You need to unzip that in the location that it is in now

I have similar issues. Mine complains that the archive doesn't contain boot.sig and recovery.sig, and then it fails to allocate space and the update package missing system.img.
Going to do it manually now to see if it works
