Create Your Own Update Packages

Here is a quick guide on how to create your own update packages (update.zip) that you can flash from your SD card using the modified recovery mode. This guide is mainly for Linux/Mac platforms, but could be easily modified for Windows platforms.

1) Download my "work area" zip file: http://dl.dropbox.com/u/42132/WorkAreaZip.tar.gz

2) Open a terminal

2) Unpack the work area:

$ tar xvzf WorkAreaZip.tar.gz

[/codebox]

3) Change directory to the unpacked work area:

[codebox]
$ cd /path/to/WorkAreaZip/

4) There is a folder inside the work area called image. You should download an existing "update.zip" file such as Paul+BigBear's ROM or the Vanilla style ones on this forum, and unzip the ROM into this image folder.

If unpacked correctly, the image folder should contain "boot.img", "data", "META-INF" and "system".

5) Make any changes you require within the image folder, such as editing the "system/build.prop" or moving APK files to/from the "system/app" and "data/app" folders.

6) When finished, you can package the ROM by changing directory back to the work area, and then running the "create.sh" script:

$ cd /path/to/WorkAreaZip/

$ ./tools/create.sh

[/codebox]

7) Once this script finishes, the [b]output[/b] folder will contain the unsigned package "update.zip" and the signed package "update-signed.zip". You will need to use the signed "update-signed.zip" package by copying it to your SD card and then flashing via recovery mode.

I thought this was a guide to making UPDATA.APPs there, and was about to congratulate you, before screaming at you for releasing it cos people could properly brick the phone.
