[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] view stored memos on previous nandroid backup?

Hey guys,
asked this question in the wrong section so I'm asking it here.
Is it possible to extract an old nandroid backup to view memos I may have had?
I don't want to restore the backup, I know something in it is wrong as it would freeze on bootup after I tried a restore, that isn't important. What is important is there were memos stored on that backup that I need back.
I used unyaffs to extract system.img, but everytime I try and extract data.img (which is where I'm guessing the memos are stored) I get a popup in windows 7x64 that says unyaffs.exe has stopped working.
I copied data.img off my sdcard and am trying to extract through windows terminal.
Can someone tell me if I am correct in thinking the memos would be stored in the data.img and where they might be located and why I am unable to extract data.img?
Thanks in advance!

[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.

[Q] Problem with nand bakcup

Hello
My problem is that I downloaded the nand stock rom from the thread and extracted it and tried to put it in the clockworkmod\backups folder and I think it was ok (not sure) but by mistake I deleted all of backups (the stock and the one i created) and I tried to copy it again and create another one but I noticed that there never 2 backups.
The one that I created I can see only from the restore option in recovery and not in the folder ( I used to see it in the folder ..) and the stock one I can see in the folders but not in the restore option.
Should it be like this ? Am I doing something wrong ?
How can I restore that stock backup if I cant see it ?
I'm on ordroid 9 with TWRP recovery.
And the stock one gets in ZIP but i extracted it and copied as folder.
Thanks in advance , I'm afraid to flash new version.

That's because you didn't put it into clockworkmod>backup folder in the sd card and btw you don't extract anything .....every nandroid backup must have 5 zip files in it (don't extract it) and should be named as the date and time it was created

The folder should be like this
Clockworkmod\backup\date & time folder\backup files

I know :\
I extracted the stock backup folder from the zip . not the content in backup.
Forgot the part about renaming, that actually might be the case.
Thanks both of you, I'll try it.

[Q] Clockworkmod backup wont delete

Hello,
I wanted to change my kernel today, back to stock, so I tried to recover a previous backup I had from clockworkmod. But when I tried to recover it said "Md5 mismatch". So I went to Youtube to figure out why this was, I followed the instructions but there is no file path for my backups. I tried all of the different file paths "/data" that was empty, "/mnt/shell/" and that was empty as well, as well as a few other file paths. I eventually gave up looking for the backup and decided to erase the backup I made. But when I tried to delete it it said "There was an error renaming your backup. Please choose a unique and valid file name for your backup." I tried renaming it something else but it still says the same thing. Anyone know what I can do here, I just want this file off of my phone. Any help would be much appreciated!
Extra info. When I made the backup I decided to rename it as "5-14(Before custom kernel) but when I got the prompt to change name, I tried changing it to a valid name. Now the name is stuck?
I've also included some pictures to help understand my situation.

I renamed the folder on my PC and it worked fine. But nothing changed. I looked in ES file explorer and folder name is still "download" and wont change

May be some problem with rom manager.Try renaming using "root explorer". If you want to get your stock kernal you can flash it using kernal flasher.

rename the folder that contains all backuped files (without space). put that folder in another folder named "backup". put backup folder in another folder named "clockworkmod". put clockworkmod folder in data/media using any root explorer (enable mount option in setting). try to restore

I used the root browser included in rom toolbox and that seemed to work. Thank you for your replies! I truly appreciate it

Thank you for your reply. Luckily I didn't have to go through that process, it seemed to go away after using root browser. Thanks again!

Anyone has an idea how to help me out?
