[GUIDE] How to extract Clockworkmod Images - Android Software/Hacking General [Developers Only]

As it seems to be a fairly common question, here is a guide on how to extract your clockworkmod recovery images.
This can come handy if you only want to extract certain apps, or files.
Put your Clockworkmod images in a folder on your computer.
Download this and put it in there, too.
Extract it in there.
Open a cmd-prompt in this folder.
Use this command to extract your data:
Code:
unyaffs.exe img_name_to_extract.img
Wait. the tool will display "end of image" when it is done.
Done. The data should be in the same directory as the tool is.
If you want to restore your contacts:
Extract the data.img
Your contacts will be in:
Code:
\data\com.android.providers.contacts\databases
I have not written the program used in this guide, just found it on my harddrive.

thanks much. so helpful
helped me to pull out contacts

I first had to download and install cgwin1.dll from here http://www.dll-files.com/dllindex/dll-files.shtml?cygwin1 and place it in the windows directory to get this to work. But after proceeding I get a "broken image file" when trying this on recovery.img and same thing with boot.img.
I am simply trying to recover some data from this nandroid backup specifically pictures in the sdcard/DCIM directory but I have no idea where it is. Is it located somewhere in the data.ext4.rar or system.ext4.rar files? If so I have looked through those and could not find a DCIM directory of any kind. Would anyone be kind enough to direct me?
Thanks

You won't be able to do that. The recovery does not backup the sdcard.

Thank you very much ,it help me much

Cheers buddy! Needed this to extract my data backup

[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.

Can you explain it step by step?
He actually told you in the post above to use unyaffs, all you need to know is already in this forum if you search for it. Here's a thread to get you started:

[Q] Need help restoring ROM manager backup

Ok so I decided that I wanted to see what all the Froyo fuss was about, so I started getting my phone ready following instructions on the site. I own a Samsung i-9000m (in canada from bell - actually sasktel but we get phones from bell). anyways, I figured i'd do a rom manager backup. I did one, had some trouble with my phone and now I need to do a restore. Reading on the web they all point to an update.zip file. All I have is the following on my internal SD
ClockworkMod\2010-11-24-14.32.54\ and the following files in that folder:
cache.img
datadata.img
system.img
data.img
nandroid.md5
I tried restoring from rom manager but it doesn't find any files, I've booted into recovery but doesn't recognize the img files......any help would be amazing. Am I missing a step, google is no help
loooks like i needed the recovery update.zip file i'm assuming.....for some reason I didn't have it in the clockworkmod folder....

expand a nandroid img file

for those who do not know how to do this yet, follow directions given here.
Just took this info from the web. None of this except for the guide is written by me.
I am not responsible for anything please do not contact me if a green sludge starts attacking your neighborhood eating one person at a time.

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!!

Google Experience only

I am happy with what I have since the new update from Viewsonic.
If I only want to add Google Experience, marketplace, do I still need to go through the process of rooting, installing clockwork and a new UI?
Is there just a simple way to add GE to the Classic UI?
Gapps install
http://forum.xda-developers.com/showthread.php?t=842590
Everyone,
I have had zip luck with this method of installing zapps. Not a dev, but I've been doing this long enough.....
I moved the Recovery file to to /sdcard. Checked for command and command line inside that file All ok to my eye.
Downloaded the gapps file which my WinRAR pronounces a WinRAR/Zip file. So I tried renamein the original update.zip and didn't get any install. So I extracted using winRAR. Still no install.
I tried the permutations as well. Extracted using G-Tablet extract. Still no results.
There must be something I am missing here -- too much holiday cheer or too many crowds or whatever.
Suggestions?!

I HAD to resort to putting on Clockwork Mod 0.8 to get GApps on my G Tablet.
Putting the update.zip on the internal and sd card storage did not work for me either with the newest update installed.
Clockwork Mod is a super easy install - just follow the instructions on how to install G Apps...basically: put CWM on your SD card in it's root (meaning NOT in any directories) and rename it update.zip, put the corresponding recovery directory on the SD as well. I use Winrar as well, I drag the recovery directory right from the file itself and to the SD Card.
Will look like:
Drive: update.zip
Drive: /recovery/command
basically.
Flash it the normal stock way (power and volume +). I press Power and Volume + without even powering off the device, because if the device is powered down and then you start it and miss that first start up, the device WILL delete the recovery/command file and the update won't flash.
GL
I don't officially get to play with my GTab until after package opening tomorrow so I can't do anything today, but I'm trying to line up my to do list. I have never rooted, flashed, or modded anything but am not afraid to play around as long as I don't brick the tablet.
What do you mean when you say "put the corresponding recovery directory on the SD as well. I use Winrar as well"? What is the corresponding recovery directory? What do you use Winrar for? I Googled "winrar" and found " WinRAR is a shareware file archiver and data compression utility developed by Eugene Roshal, and first released in the fall of 1993.[1] It is one of the few applications that is able to create RAR archives natively, because the encoding method is held to be proprietary. " I cannot figure out why it would be needed to load the standard Android market.
MSU_Sparty,
When you do updates (or installs) that have to be flashed onto the internal sdcard, they usually com in pairs of files. You will have an update.zip file that has the update in it (DUH!) -- and accompanying it will be a "Recovery" directory that has a command file in it (The command file has only one line that "calls" the update.zip file.
WinRAR "Zip" utility enters the picture because most of the devs here use WinRAR to package updates. The when they tell you to decompress it, you use WiinRAR and are left with a .zip file to install.
That's the question I had about this update. The Gapp file show to be a RAR package, but when I un-RAR it I come up with no .zip file -- only regular files.
Hope this helps you understand.

P. S. -- If you are new to this business, take it slow and easy and read ahead on this site and make sure you understand what you are doing. I try to do that, but even with years of IT experience I still mess things up once in a while.
Neoprimal,
Thanks for the tip about CWM. I have two tablets and the other has CWM on it and is fairly modded.
But this tablet I am trying to keep basically stock so I can get updates, etc. and see what the "state of product" is.
As mentioned in my previous answer, I am stumped because I am not getting what looks to be an update.zip file from the Gapp download. When I use WinRAR to decompress the Gapp file, I don't get a .zip file -- only a couple of directories. On the other hand, when I rename the Gapp file update.zip and try to flash it it doesn't work.
Again, thanks for the reply.
Anyone else with suggestions!!!????
Rev
Thanks. What you've written really does clarify the previous post. I appreciate it.
But let me ask another naive question. Why don't the developers create their update programs so they can be installed by just downloading them OTA like most applications? That would sure make it easier for neophytes. I'm guessing that the reason is because we aren't really adding an application but replacing the OS.
I greatly appreciate your guidance and that of all of the folks who use this forum.
Happy Holidays!

How do I manually extract the backups I made using TWRP?

Hello,
In the ROM'ing journey, I backed up everything using TWRP on a OnePlus6.
I have all the files shown below here, but I am not sure how do you view them on the PC, as in what tool do I use? Using a archive tool doesn't work, from what I can see there are multiple part files and the archive tool doesn't seem to detect it.
I basically just want my DCIM, and Audio recordings out of it as of now.
rename data.ext4.win files to tar (or tar.gz) and open with 7-zip. these files aren't multiple part files. open each file on its own.
pictures are in data/media/0/DCIM/Camera and therefore not included in TWRP backup.
Oh, I see. Never thought they wouldn't be included by default, I thought backing up backs up absolutely everything
there's a warning on phone screen
also in documention
