I'm having the same problem with my Huawei Ascend P2.. Huawei released an update for it but its saying something about "stat'ing" the update.app file? so I just removed that part of the script from the updater-script file (located in META-INF in the update.zip)

Extract *.apk?

If I have a *.apk that I download, is there anyway to backup/extract it?
The apk is really just a ZIP file. Try renaming the file to whatever.apk.zip and open using your favorite ZIP utility. You should be able to view all the contents. Resources (such as images) can be extracted. The java code is compiled into a .dex file so you can't view the raw code, but there are utilities (like this one) to decompile it: http://dedexer.sourceforge.net/

Right but how do I find the *.apk if I am downloading it off of the market?
apps are located in data/app/
There are also various apps in the market that will backup apps.
I use appmonster incedently.
7zip can extract and view contents of an apk without renaming.
backup and reinstalling apps....
view the first link in my signature.
I used MyBackup Pro to do a backup of my apps onto the sd card, then I used ASTRO file manager to navigate to /sdcard/rerware/MyBackup/AllAppsBackups where I found the file LastBackupApps.zip. I then used androzip or something similar to unzip that file and it contained the apk for every one of the apps I backed up.

I have a zip file with .apk.p files in it which are exracted with package_extract_file in the updater script. Is there a way to manually extract these, since renaming to .zip doesn't help if I open them with any unzipper program?
Thanks

I believe the files you are referring to - the files ending in ".p" - are "patch" files. They only appear in the OTA download .zip file, and they are worthless to you. They are not complete files, but just enough data to patch the corresponding 1.5 app .apk so that it turns into the 2.1 version.
If you want the complete .apk files which they correspond to, just download the Leak-V3 .zip file, extract the "system.img" file, and then unpack that file using the "unyaffs" utility (search for it, you'll find it at code.Google.com).

Thanks for the info. I thought I can update the apk files manually, because from recovery it doesn't work (it is a rooted image, so signature not accepted) and there are some fixes in the new update that I wanted to give a chance.

[Q] How to create a custom ROM for SmartQ Ten3 T15?

Hi all,
I have a SmartQ ten3 T15 Android 4.0 tablet (TI OMAP 4430 SoC) on the way to me from China.
As I like to have all files on hand before gadgets arrive, I downloaded the standard firmware yesterday from the SmartQ website.
As I read somewhere (don't know where) that sometimes firmware files are zip files I renamed the extention-less firmware file to .zip and I could just open the file with winrar and extract the complete file structure of this ROM.
That got me thinking of creating my own ROM files, but first I'd like to have some questions answered by people with experience doing this.
Normal firmware update on this tablet is done via micro SD card, and by entering a boot option while holding down certain keys.
The questions:
- Is it as easy as putting in or taking out the files in the folder structure, zip the files and remove the extention and update it to the tablet?
- Winrar says the file is signed with signApk, but this also seems a very straightforward procedure to signing my own ROM's. Or will the tablet only accept files signed with their certificates?
- Anybody else have experience with firmware files for other devices who work the same way? And do you have tips for me?
One of the things I'm trying to achieve is getting bluetooth and FM to work, the hardware supports it but it is disabled by firmware.
And further on I would just like to customize the tablet further, by removing apps and adding my own and so on.
Thanks in advance for your help.

How to extract files from ROM

Hi,
As the new ICS 4.0.3 seems to have gotten rid of the libraries required for call recording, I am willing to extract the relevant libraries from a 2.3.6 ROM, replace and give it a shot. I already have a few of them with me, for example Official DXKL3.
I need to extract the following 3 files -
system/lib/libaudiopolicy.so
system/lib/libaudioflinger.so
system/lib/libaudio.so
How can I extract these files from a ROM?
On you pc or on you phone click extract here. And will be exctracted about 6 files. Navigate to system app and find wht app you want. Copy and replace. I guess I understood right what you mean.
Get a utility program like 7Zip, IZarc, WinRar on your PC & open up the zip/tarfile & you can see the individual files & extract same.
However...
What you're attempting to do will not work. Different framework.
Points for thinking outside the box tho.
Thanks... Though when I use 7z, it only extracts zImage,factoryfs, etc., only a handful of files. I cannot see the individual files in the file system. Also 7z cannot extract these files anymore...
Ahh I think I was talking about already "cooked" ROM, and you guys are talking about the source? Sorry I am very new to the terminologies used. If that is the case I will check if I can find these files in the source tarball.
Try another program if 7Zip doesn't work. Try IZarc. I can see every file in the roms I have with it.

[Req] Extract apk from image file-how?

Hi all. Can an apk be extracted from an image file?
The image file is the .tar.md5 of the official UK ICS update from sammobile.
I've done a search and so far can't find how to do this.
Is it even possible?
There's a particular app in the UK version that's not in the US version I want to install
on my US 7510 wifi tab.
Thanks.
As I know, .tar files are archive file like zip. just for Linux. have you tried to open it with 7zip.?
I don't know if it works, but maybe.

Tried WinRar but doesn't get me into the tar file to see the apk's.
Will try 7zip.
Thanks!
