read/edit .img files

Does someone know how to mount/read/edit the .img files in the ROM?
I Know it is a small filesystem.
I googled for an hour and still don't know how it works.
For example the Radio ROM, i'd like to read the contents, Why is it for about 25MB's
Is it possible to tweak the contents and stuff.

Not sure about radio rom.
unyaffs for system.img
unpack-bootimg.pl/repack-bootimg.pl for boot.img

I think you want unyaffs. I used it to decompile a nandroid backup .img so i could take some files form it.
EDIT: Damn you Adam!

unyaffs says `Broken image`
So that won't work.
will try: unpack-bootimg.pl/repack-bootimg.pl
but i think it's for the boot.img file.
also intresting to look at.

[Q] how to extract .apk from a nand backup?

is it possible to extract an .apk file from a nand backup made with Amon_Ra (1.8)?
i switched roms to MIUI and i can't find Volume Button Controller on the market. I've had it on my phone for months and I can't function without it. i've searched online and all i come up with is broken market links and links saying the app has been removed from the market.
it was a free app, that I have on a backup. just dont want to have to backup my current miui setup (in progress), to restore that one, to restore this one again, etc. plus i think knowing how to do this will be useful in the long term.
i'm on Windows XP so I'm restricted to that platform on terms of getting it to work. google search turned up an app called unyaffs but it looked like a linux thing
thanks!

backup what you are on. restore your nand of where you have the apk. and then use titanium backup to backup your app. Restore your latest nand and use titanium to restore the app.

You can also extract files directly from the img files. Install Cygwin with the default options and download unyaffs compiled for windows. Place unyaffs in your path for ease of access, copy the system.img file out of your nand backup and drop it into a folder that is easy to get to. Start Cygwin, cd to the folder the img file is stored, type unyaffs system.img. That will extract all the files from the system.img file. Most of what you need should be in the app folder. Some things will need stuff from the lib folder too, like swype.

thanks for the info.
ended up going the route i didnt want to go. installing cygwin was taking forever!
but now i know for the future

Yeah, Cygwin can take a while if you are on a slow connection or get stuck on a slow mirror.

[Q] Backup .apk files that are stored on an HTC Desire HD (rooted)

I have searched this forum and have not found an answer. I would like to know how to backup the .apk files that are stored on the phone memory, not the SD card. I have used ASTRO file manager but cannot locate the .apk files. I have already used Titanium Backup Pro but I have found that the .apk files are backed up a .tar.gz files. What I want to do is backup the .apk files as .apk files for future resoration or transport to another Android device. I have searched the phone and cannot loacte where the downloaded .apk's are being stored. Could someone out there please help point me in the right direction.

You have a couple of options. You can tell titanium backup not to use compression when backing up, or you can use 'Root Explorer' and navigate to /data/app where you will find all your user installed apps, be aware that the data for the apps, such as save games etc... is stored in /data/data.
Hope that this is of some help to you.

Tahnsk for your help
Doktaphex,
I tried turning compression off but titanium backup still created .tar files, not .apk files. Secon option of using root explorer worked just great.
Thanks for your help.

You can use Titanium backup, which will create compressed file, but you can decompress it on your PC and extract .apk file.
Method I use is with ASTRO. Go to menu-tools-backup programs, choose programs you want to backup and hit 'Backup' button. Then navigate to backup folder and there are your programs. But be aware, they will show market names whic are not always easy to determine which .apk is which program.

I use appmonster as it backs up when you install from any source, using an old version 1.9.0 as they changed the way it puts file names, nopw it does via market, on prior it was a readable name

I am using app saver, it works~

A simple option would be to install appInstaller (the one by Gregory House) from the market.
It's a lightweight app which backs up apk files to a folder on your sd card named app saver.

Noob here,
how can you locate or transfer a apk files? where are they exactly saved? how can you install/run them? what app should i use?
using a Huawei u8860 phone.
Thanks

It all depends of the app...if is a system app or a market one. You have to use a file explorer such as file manager or ES explorer.
If the app you are looking for is a system on you need to be rooted.

Try apk extractor in the market its free, its what I use.

nandroid.md5 files explore

Hi there,
I have some previous backups (nandroid.md5) files and I would like to explore them in order to retreive some files.
I am looking for a way through mac or win 7. I do not want to restore te back up version.
Any ideas ?

I don't know about files but you can get apps from a nandroid via appextractor
And PLZ!!!!!! QUESTIONS IN THE GENERAL SECTION...... EVEN IF THEY ARE DEV RELATED!!!

The md5 contains only the files' checksum which is used to check if is corrupt or not. You really can't extract any information from them.
The main content lies in the other files.
You can use unyaffs to extract and view the files.
The sd-ext partition is backed up in tar format so you extract it using tar.

'nandroid browser'
Great tool for extracting single files/folders from a nandroid backup without restoring.
It's been very usefully for me.

sorry guys my mistake.
I need to retrieve all camera photos from a backup image.
I just noticed that the md5 file is too small to contain images and I found some .img files.
Is there a way I can extract them straight to my pc and not from the phone?
I find it hard to locate the files through nandroid browser.
Thanks a lot for you help and apologise for the incovenience.

Your camera pictures are saved to the sdcard and not a nandroid backup look in the DCIM folder on your SD card :thumbup:

Wifi Tethering on GB27 rooted without flashing?

Is it possible to have WIFI tethering on GB27 rooted without having to flash it in? I have the stock but rooted GB27 on my Sprint Epic 4G touch and would like to occasionally tether my tablet to my phone mobile data.
I did some research in the forum but haven't found one that did not require flashing it in and I have had trouble in the past with this way of installing it.

Hi. When you say you've had trouble in the past, do you mean with crawrj's hotspot mod, or is flashing anything in recovery the problem? I only ask because if you're not comfortable doing anything in recovery, I wouldn't want to suggest other root actions really, because I'd always preface by saying to make a backup... And if you're not comfortable making a backup, I would be concerned about your modifying system files to begin with. Not saying this for any reason other than caution, bud... making a backup and flashing tested mods are your safest approach.
If you must:
I need to be clear that you make any system file changes with a risk, minimized by making a backup first.
What the flashable mod does is replace two small, important files in your framework folder. (Make a backup first?)
Download the correct mod. It will be a zip file: http://forum.xda-developers.com/showthread.php?t=1879140
Don't extract the zip, but dig into this folder: system\framework\.
There are only two jar files in there. You need to copy them into the corresponding folder in the file system on your phone. So copy the services.jar and wimax.jar you just got from that zip and paste them into system\framework\ folder on your phone. You'd do this using a root browser such as ROM Toolbox or ES File Explorer.Paste those two jar files into the framework folder. Long press on each and verify/change the permissions to be 0677 (or RW-R--R--). Reboot.

Thanks for the option and advice. I used to flash my Nexus phone all the time with no troubles but ever since I came to the Epic 4G Touch I have had issues in flashing. A couple times I came close to a hard brick. I am used to using root explorer or ES File Explorer and could easily backup those two files. Since settling into GB27 I should probably look again at putting AGAT's recovery on my phone. I will look at the info in your link.
