Resigning ROMS?

Ok so im a noob when it comes to coding. I want to replace the wallpaper that comes in some roms and from my understanding when I extract the .zip rom to replace them, I have to resign the .zip for it to work. If this is true, how do I resign them?

first make sure you grab all the signing tools (do a search and you'll find Stericson's stuff somewhere)
extract the zip of the update.zip
now in the main folder you should see META-INF
go in there and remove the three files that are not folders
now go up one level back to main folder
depending on how they packaged the update, you should see either a system or app folder
if you see system, then go into it and then into app
if you see app, then go into it
now you should see some .apks
the one you want is Launcher.apk
use 7z and open the archive
now navigate to the res/drawable folder and you should find your wallpapers in there
just use the name of a wallpaper thats in there that you dont like and replace it with the wallpaper you want
now navigate to the main directory of Launcher.apk
delete the META-INF folder
now close 7z
resign Launcher.apk
now navigate to the main folder of the update.zip
zip it all up again and resign the new .zip file
sorry if the instructions arent that clear .. its kinda late and been studying for a midterm for some time now .... PM me up if you need any more help

Note, this will not work if your SDK or the path that you place this in has any spaces in the dir name!
An Example of this is c:\users\Nikki and Stephen\sdk\tools
Try to put the SDK and the contents of the zip in a dir where the names are all together and not like the one above.
Ok, so I have made a batch file that will automate the entire process of setting up to use the signing tool made by JF. This batch file will set the CLASSPATH, set the PATH, install the registries, let you sign the files manually, and let you push/pull files to the phone.
In order to use this you should have downloaded the sdk already. Simply extract all of the files into the tools dir of your sdk, and run autosign.bat follow the instructions and go through the options one by one, starting with 1 working through 4. You can however, put the contents of this zip anywhere on your computer and it will work. It is just better to put them into the tools dir of your SDK. Especially for the consideration of future versions.
Enjoy,

[help] how to make a update.zip???

hey does anyone know how to make a update.zip for a apk???

you need to create an update-script that basically tells the flashing app where the file of your apk goes in the live system.
zip and sign and you're done.
if your next question is "how do I write an update-script" I would suggest you download any of the roms available, extract their script and have a look at it.
its quite basic, not much more difficult than writing a batch file on DOS.
there are a couple of threads that give a few pointers as well but they are somewhere in xda, not necessarily in the nexus section.
search for update-script and you'll see.

thanks mam ill give it a try

Remove the .txt extension or use the META-INF folder in the .zip that already has the same update-script in it or finally, you can use the empty update.zip which already has all the components in it, you just need to add your .apk's and .jar's to it.
This is a basic update script that works well for themes (or at least for me it does). In your .zip have META-INF (for the update-script) folder (take one from a ROM or theme) and an app and a framework folder and it will work.

Recompile APK help

I'm a noob at this... I searched the forum but couldn't find any information.
Could someone more knowledgeable explain to me how to decompile and recompile apk's?? More specifically the framework-res??
I read that you can't simply unzip and then rezip... so what do I have to do?

The apk's are zip files that contain the resources (icons, bitmaps, sounds, etc.) as well as the code compiled in a classes.dex file. You can replace the resources after deodexing, but I don't think you will be able to change the compiled code in classes.dex unless you have the source code.
Sent from my SAMSUNG-SGH-I897 using XDA App

So for instance... if I have a clockwork flashable battery mod... and I unzip that... and edit colors of icons in the framework-res.apk, then can I just save the files, recompress and it will still flash properly?
And another thing.. if you have a clockword flashable .zip how do you change it so that you can flash via stock recovery? I know that simply renaming it to update.zip and trying via stock will not work. Is it a hard process, do I need a special program on my pc??

make your life easier..
search xda for Apk Manager

I am not sure about editing apk's. To create a flashable zip file through stock recovery, you need to have the META-INF folder correctly created with a working updater script and the manifest and certificate files that you get by signing the zip file. Look into playing with the HTC android kitchen on the chef central section here to automate that process.

[Q] I want your help.......?

hi
I have original 2.1 (eclair mod ) installed in my milestone
and i want to customize it ( change status bar, add and remove apps.......)
without installing new custom rom.
so can any help me how to do this ?
thanks in advance

i use 7-Zip to open .apk then you can edit/replace file in apk file
to change or edit .9.png file you need other program like 9patch or draw9patch to save in good format.
the main file to edit is framework-res.apk practically all theme is in that file
all system file does not need signing but all other should be sign before you put back in phone and don't forget to zipaling all file that you touch/edit.
many tutorial are available on the net on how to theme android for more in deep detail.

thanks a lot
I'll try

well first do a nandroid backup of your rom then copy to pc, now extract system.img with unyaffs.
then you have all system file of your rom to play with.
after all your change copy file to sdcard/openrecovery/update/test-update-nosign.zip, don't forget to remove babble
i am using OpenRecovery_v1_46
hope it help

I've done it and i hope it works

boot,bpsw,data.img........
are these files important in making custom rom?
thanks again

Extracting files from KDZ

HI,
I am trying to get an apk from a KDZ file. I can open up the KDZ but then there are many other files inside. I guess the apks are in one of these other files. Does anyone know how to get the apk from within .img files etc?
Thanks

How you extracted KDZ?

Why don't you get it from the sapps module zip on void's rom?

I need a particular app from the Orange UK ROM - the app is called Signal Boost and it is for UMA calling.
Is that app in the ROM you mention?

What you need is this: http://forum.xda-developers.com/showpost.php?p=6303911&postcount=827
It allows you to decompress system.mbn (where all the files are).
Compile it under linux, or use cygwin.
Remember that official ROMs are odexed. If you want to deodex apks, you can use dsixda's excelent kitchen. It is used to make lots of ROMs you see around here.
For that, take a look here (you can also use it under cygwin):

Most info was gathered from xda forums, only translated and organized to portuguese folks.

Many thanks, I will see if I can get anywhere with this.

You just need to compile unyaffsmbn (gcc unyaffsmbn.c -o unyaffsmbn).
Then copy system.mbn to unyaffsmbn folder. Then do:
./unyaffsmbn system.mbn
You'll have all files extracted in few seconds.
Then if you want to use those files in kitchen, do this:
First install kitchen, as explained in link i posted above.
Delete all symlinks in bin/ (i think there are 52)
Then you must create a zip file with this structure:
/boot.img
/system/ (here you put all the files you extracted. You should have 10 folders and 1 file)
Now just copy this zip to PATH_TO_KITCHEN/original_update/
Then run it with:
cd PATH_TO_KITCHEN
./menu

Right I have three system.mbn files named:
system.mbn_0
system.mbn_1
system.mbn_2
I have tried a few tools (under Windows) to extract them. Firstly a windows compiled version of unyaffs which falls over with : Exception: STATUS_ACCESS_VIOLATION at eip=61100F73
I then tried another version which didn't error but also didn't do anything!
A different tool errored with "the header states that its binary is longer than the whole file" which makes me think perhaps these three files need combining into one?
I have tried combining them into one file using the copy /b command in Windows which creates a single large file but I still have the same issues trying to unpack it.
Any more ideas? Thanks

Right have now installed Cygwin and managed to extract the files using unyaffsmbn! Thanks for all your help, learnt a lot today!

How did you decompress kdz? I use LG Utils to extract to dz, then dzdecryptor to decompress dz to individual files. Then i use the tools i named to do the rest of it.
Also i can see that lg utils finds those system*, but puts them together before it ends. Maybe you used different software.
Anyway, i'm glad you managed to work it out

There is unyaffs, and unyaffsmbn. unyaffs also never worked with me.
I've read somewhere that with lg roms we must use unyaffsmbn. Don't remember were i saw it, neither why...

I used LG utils to extract the KDZ, then used DZExtract to expand the .dz file. Then I combined the system.mbn_0,1,2 files using copy /b.
I then used Cygwin and gcc to make unyaffsmbn.exe which then worked on the combined system.mbn file. Managed to get the apk I needed too.

PLease upload unyaffsmbn.exe for me please as i seriously need it.

Here you go...
