Hi all! This is a guide from PIRATEPARTY about the creation of a simple UPDATE.ZIP to flash on your Android phone, in recovery mode.

I've created a repository on GITHUB where you can download the "update.zip" that we'll use and modify.

So, this is the repository: update.zip--for-Android-Devices-
You can download it as ZIP archive and rename it as update.zip .

So, we have now the most important file, that we're going to modify:
All the apps that you want to insert in the archive and install on the phone, must have the .apk estension and you have to put them in /data/app . Then, if you want also the app data files, you have to take these files from your phone, going with a rooted file manager (i suggest Root_Explorer) to /data/data , copying the app folder and pasting it in /data/data of the UPDATE.ZIP.
So we have all the apps and datas that we want. Now, we have to write the script.
Let's go to META-INF/com/google/android/ and open 'updater-script' with a simple text editor.
The only lines that you have to modify are:
Code:
set_perm(1000, 1000, 0644, "/data/app/[PACKAGE].apk");
set_perm_recursive(1000, 1000, 0777, 0777, "/data/data/PACKAGE_DATA_FOLDER");
delete("/data/dalvik-cache/data@app@[PACKAGE].apk@classes.dex");
For each app you have to write these lines. This is an example if you want to put ROOT_EXPLORER.APK in the UPDATE.ZIP:

Code:
set_perm(1000, 1000, 0644, "/data/app/ROOT_EXPLORER.APK");
set_perm_recursive(1000, 1000, 0777, 0777, "/data/data/ROOT_EXPLORER_DATA_FOLDER");
delete("/data/dalvik-cache/data@app@ROOT EXPLORER@classes.dex");

That' all. But if you want to delete some apps from your phone, you have to write between
Code:
ui_print("| 80%  Installing Applications |");
and
Code:
package_extract_dir("data", "/data");
this line:
Code:
delete("/APK_DIR/APP.APK");
IT'S IMPORTANT TO LEAVE AN EMPTY LINE AT THE END OF THE SCRIPT, OTHERWISE THE ZIP WON'T WORK!

You can easily find the name of the app going with Root Explorer to /system/app and searching the same app.

If you also want to add your modified Apps, you've to sign them with a simple app: Auto-Sign, putting them in /auto-sign/update/app and renaming it to Launcher.apk .
You can download AUTO-SIGN from the attachements!

With it you can sign your apks or your zip. So, finally, when you'll finish your zip, you'll have to put it in Auto-Sign folder ("/auto-sign").
Then, open Auto-Sign, choose your zip or apk, and click AUTO-SIGN. It will create a new apk or zip, name as SIGNED-apk/zip.

Now, you only have to put the update.zip on your sd-card and flash it! Have fun guys!

mackief,

Thanks for your tutorial. I wrote a removal script for GB that deletes everything i don't use in my ROM. I recently moved to ICS and that very script is still working but, each time, during restart, I lose root rights.

Any idea where it could come from?

What rom are u using?? What device??
I think that the problem is about the rom, cause you said that u didnt have problem in previous rom and you used the same script...
So, to find the problem, i have to know the rom, the device, and the script.
Can you post the script here?

mackief,

Sorry for having been so long to answer, I was not monitoring the thread

I use nightly CM9 roms for my Note (N7000). You'll find attached my latest script that still bothers me.

If you can have a look at it, it would be nice.

I read your script, but i think that the only problem is about the root app: Superuser and his components. So, check out if some elements that you want to delete are associated to Superuser, and dont delete superuser.apk .

However, usually, in CM9 there are some apps that you CANT and HAVE NOT to delete. I suggest to you to read this file: REMOVABLE APPS

So, Superuser gives you root rights, so dont delete it.
Dont delete the list of apps that is on the link above.
The last suggestion is that you have to check if you're deleting something else that can create bugs with superuser and his working.
Write me if you want to know something else or also if these solutions arent useful: i'll help you! Bye!

Interesting guide. I am curious though, you have it setting permissions but have you tried it without doing so? I ask because I made a script for CWM which copies my apk's to data/app/ and I don't set permissions and have no issues. In theory you shouldn't need to, the apk should retain the proper permissions even when copied. As well, why not set the permissions for the entire contents of the folder, ie, set the permission recursively like you do for data/data and have it run at the end of the script once everything is copied?

Lastly, one thing to note with this method of installing apps is that your first boot will take awhile, the ROM has to create the Dalvik for all the apps you just flashed, I hadn't considered that when i first ran my script and thought something was wrong.

At first, i have to say to u that permissions can be not specified: i think that all the files that u put in a folder have the same permission of the folder. I set permissions only for safety.

Then, about the first boot duration, there's nothing wrong.
The system only take a while to put into effects the changes, creating the Dalvik for example.. Don't worry: it's normal!

I know it's building dalvik, it simply hadn't occurred to me initially that that was the reason for it not booting. A file can have a different permission than the folder, but I think it's only that you can have the folder r/w and a file r/o. Then, on your script you can just set permissions recursively and save yourself setting permission for each app/file individually.

Before CWM 5, I used to have a script that would let me add lots of files without individual lines for each.
It worked similar to gapps, where files are separated by commas.
Any ideas?
I will be adding sound files to system/media/audio/alarm.
