I'm looking for a guide which tells how to make a own custom ROM from another one
I mean:
1. How to add/replace/remove apps in /system/app/?
1. a) Do they need to have special permission?
2. How to replace boot screen?
3. How to add custom kernel?
4. How to add Desire lockscreen/flip clock?
5. How to add transparent notofication area?
6. How to add Power menu?
I've been serching forum, but didn't find such tutorial. Would be very thanful to get this knowledge.
I think that will be very useful for maaaany android maniacs
1. Simple delete/copy apks in .zip file using 7-Zip or any other.
2. I belive you need to put bootanimation.zip in /data/local/ folder.
3. Idk
4. For Desire lockscreen you need edited HtcLockScreen.apk; for flip clock - HtcClockWidget.apk
5. Edited /system/framework-res.apk or /system/framework/com.htc.resources.apk. I'm not sure
6. You need edited /system/framework/android.policy.jar
69. Resign your zip file using Auto Sign
Attachment doesn't load, but I know about resigning ROM after everything is done
Ad. 1. As I thought, but do the need special permissions? And I also wonder one thing. Are they installed while flashing? Cuz they need to be in system registry, I think...
I have found this: http://wiki.android.com.pl/wiki/Kon...iana_instalowanych_aplikacji_razem_z_systemem
No any permissions etc.
Found this, too. Thanks.
to add a custom kernel you have to unpack the boot image and edit the ramdisk manually, although i think there is an option in dsixda's kitchen to unpack and repack the boot.img
I've got two more questions:
1. When signing, three files are created in folder META-INF: CERT.RSA, CERT.SF, MANIFEST.SF. But in other packages I see also com/google/android/update-script in META-INF. How to make it? Is it necessary?
2. If I want to make only flashable update file which changes one app or another file, eg. framework-res.apk, I have to create folder structure: system/framework/framework-res.apk, add it to zip archive (no compression?) and sing using Auto-sing. Am I right?
Edit:
Found nice guide there: update-script syntax

The most important part of a recovery update zip is the update script. It will tell the recovery what to do. If you want an example of a basic update package, which replaces one file in the /system/framework (although a different one) can found here. Open this and read the META-INF/com/google/android/updater-script (or whatever its called). The syntax is pretty straight forward and I think its easiest to learn from the examples of updater scripts found here on XDA. For the simple case, of only replacing/adding files to the /system partition you can leave the updater script from the above example as is and only change the files under the /system directory in the zip.
Note, that the above example uses the newer upader-script (I hope I am writing this correctly, I am writing from memory) which also has a binary file in the same directory. Some update zips use the older "update-script" lone text script. For these kind of scripts, you can find a guide here.
Personally, I use RA recovery, and for this recovery you need to sign the update zips (last thing you do of course). At least for RA recovery, both the older "update-script" and the newer "updater-script" work fine, so its up to your personal preference which do you prefer.
Thanks. Found a guide you mentioned a couple of minutes ago and read it.
The more I know, the more questions it brings So one more thing. If I'd like to use the newer version of syntax: "updater-script", I need also to put this binary file in this folder. But I create/edit only "updater-script", binary file is the same for all packages, or do I need to edit it, too?
I built a kernel tool long time ago, very easy to use (only for linux)
1: unzip the file, place it where you want it eg your desktop
2: place boot.img in the working directory
3: double-click the menu icon or launch from terminal
4: it creates a new directory named BOOT-EXTRACT,edit what you want in there or change the kernel etc.. and repack it again via the kernel tool
see screenshot. here for those how want the tool >>> http://www.elelinux.se/tools/kernel_tool.zip

Only the updater-script. The binary is a replacement of the script-interpreter I think, but thats just an assumption.

But it is for MS Windows, or saw I wrong ? I have also built a tool to javasign files,but should probably write a manual first,it is easy to use but some dependencies maybe not so easy for a beginner with Linux.

***I added some minor reliability improvements, by including more error checking, seems to run pretty smooth***
I've been playing around with making a deodexer script and having some issues, did a google search and came across these two posts.
http://forum.xda-developers.com/showthread.php?t=598026
http://forum.xda-developers.com/showpost.php?p=5775540&postcount=57
So I merged what I had with theirs and modified it to work on the Captivate ROM's.
I thought it would be a useful tool to have and thought I would share with anyone interested in deodexing their own stock ROM.
Why would you want to deodex your own ROM when you could download somebody elses? Something to do I guess.
It deodexes the app and framework folders in three passes, the first pass does the files that don't require a specific boot class path, the second pass deodexes the files that do require a boot class path and the third does a check for any files the for-do loop may have skipped.
It takes approximately 10 to 30 minutes to complete, depending on your computer, but considering that it took me almost a day to deodexed a ROM manually, , thats not so bad.
It can pull a stock ROM from your phone and deodex it, using adb or you can extract a factoryfs.rfs file and place app and framework folder into the app and framework folders for the script.
It also has a batch zipalign tool for when its done deodexing.
You have the option to select boot class paths for Captivate i897 (gingerbread or froyo), or you can input a custom boot class path string.
Extract the Deodexer_i897.zip to a folder that does not have spaces in the name.
Pull the system from your phone or add your app and framework folders to the extracted folder for the deodexer.
Then just doubleclick on deoall.bat and your off and running.
I included a Readme file with instructions.
You have to have the Java sdk and samsung usb drivers installed on your computer for it to work.
The script is a windows batch file and was modified on Windows 7. I assume it will work on XP as well, but haven't tested it.
I've tested it on:
i897 - KB1, KF1, KH3, KI1, KI2, KJ1, KJ2, KJ3, KK1 and KK2
Rogers - KH2
i9000 - JVO, JVR and JVS stock ROMs.
I've flashed and tested KF1, KH3, KI2, KJ1, KJ2 and KJ3 on my phone with no problems.
(Remember, stock KH3 - KJ3 do not have any ringtones so you will have to copy them to the media/audio folder from another ROM)
Note: Remember to check the app and framework folders for files that got skipped. If there is, try running the deodexer again just to make sure it just wasn't a glitch.
Thanks and credits goes out to Daneshm90 and crzyruski for the deodexer scripts and JesusFreke for giving us baksmali-smali and not to forget, Igor Pavlov for 7zip.
UPDATE- I'm adding a basic clockworkmod flashable script template that you can pop your system into. It includes redbend_ua, wipe, busybox, su and superuser.apk for root. You will have to add a kernel (zImage) and the appropriate modem (modem.bin) to the updates folder.
You will have to flash an update.zip (Froyo) http://forum.xda-developers.com/showthread.php?t=734163
or flash a kernel tar using odin, that has clockwork mod baked in (Gingerbread), and will need to add a cwm modded kernel to the update folder in the template if you want to keep clockwork mod recovery (Gingerbread). The template will not work with special kernels that have scripting included such as init.d, you will have to flash special MOD kernels that contain scripts, afterwards.
*****CAUTION:This is a full wipe template so be careful and know what you are doing.*****
***Fixed the Core_ROM.zip so it will install the modem and kernel, plus added the wipe script.***
It is beyond the scope of my talents and time to completely teach someone how to do all of this, but google is your friend when it comes to learning this stuff. There are allot of resources out there to help you accomplish your task. I'm just merely supplying some basic tools for you.
TOOLS
Notepad++ works great at editing the updater-script in the META-INF folder.
And the smali and xmls in the apks and jars.
http://notepad-plus-plus.org/
And Apkmanager is great to decompile and compile apk and jar files - Thanks raziel23x
http://forum.xda-developers.com/showthread.php?t=1227179
Just add .apk to the end of the .jar, do your modding, change it back to jar when you're done, works great.
Plus raziel23x has a new apk multi tool that is still in beta but is worth watching http://apkmultitool.com/
Also for those that want a free alternative to Photoshop to modify your graphics, there is a great program called Paint.Net http://paintnet.org/
If you are serious about MODDING here is another valuable tool, Beyond Compare available here $$ http://www.scootersoftware.com/

For KF1 I found this link for the cog5-beta2-kernel.tar, thanks to designgears. http://ftp.captivate.org.ua/samsung/captivate/2.3.x/2.3.3/ROM/cognition_5/
And of course, for KH3 and KI1-KI2 use Boogs kernel available here http://forum.xda-developers.com/showthread.php?t=1242533

***The script has been updated to include the boot class path as an option, instead of having to copy and paste the whole thing, so the Bootclass_path.txt file is no longer needed... Thanks to ralphreyes ***
**NOTICE: due to the nature of DOS (Windows) environmental variables, the deodexer needs to be extracted to the root folder, or any folder it resides in, can't have a space in its name. e.g. Android SDK as opposed to Android_SDK***
As always, I am not responsible if it messes up your phone.
I hope someone finds this useful.
***NOW ITS FINAL***
This is awesome !! Thanks for sharing.
I will have to check this out when I get time this weekend...or sooner.
What about an odexer?
I would like to odex the ROM on my phone after I get my desired modifications in. Any chance on an odexer script?

Odexing is a little tricky, I haven't found a compiler to do that, something exclusive to google and phone manufacturing developers. Though the performance of an odexed ROM is so slight over a deodexed one, it probably wouldn't be worth it.
Nice job on the "Read me".
Will be trying my hand at this asap...
thanks again

**NOTICE** I added another deodexer for high performance computers with quad-core or high end dual core processors, even though the original deodexer works fine, because the script would run so fast, it can produce errors, or skip files because of possible memory segment overlap, causing null pointer exceptions, so I added a 3 second pause between each operation to solve this issue. It only adds a minute or two to the deodexing time, but should add reliability and integrity to the deodexed ROM -> Deodexer_i897x.zip

I thought I would make it a little easier on your script by adding a couple extra lines to the 'deoall.bat' file so the bootclass path is included within. When it prompts you to enter the bootclass path, you can enter 1 for GingerBread, 2 for Froyo, or you can just enter your custom one.
Replace the line that starts with
Code:
set /P INPUT=Enter BootClassPath (ex 1.jar:2.jar:3.jar): %=%
with the following:
Code:
echo Enter BootClassPath: 1=GingerBread, 2=Froyo,
set /P INPUT=or custom (ex file1.jar:file2.jar:file3.jar): %=%
IF %INPUT%==1 (set INPUT=core.jar:bouncycastle.jar:core-junit.jar:twframework.jar:services.jar:framework.jar:seccamera.jar:javax.obex.jar:com.google.android.maps.jar)

I'm a new developer and have applied all my tweaks and edits via root explorer so far. is there a way to change a CWM backup into a flashable rom file for other users to flash? I searched around a bit, but couldn't seem to find anything about it.
Goto this thread here
follow all the setup to install cygwin & kitchen
once it's all setup you can plug your phone in and create a rom
follow the guide (second method) for creating the rom system files by extracting the system folders from your phone (rom you are using)
you can then turn it into a flashable rom zip
I think you just basically extract the CWM backup, then repackage them in 1 zip file (except for the androidsecure backup).

Hmm thats how i make roms that i dont post here though....
In tthe cwm backup u have system.rfs.tar
Extract it using 7zip
U get system.img or u might get a system folder....
Extract the img file using Magic Iso
Open magic iso
In menu..
File>open
Select ur system.img
On the left side pane right click on the disk icon and click extract.select ur destination
Once the files are all extracted copy all of them in a folder named "system"
Now get a meta-inf folder from a custom rom and zip
Meta-Inf and system folder together
U have ur rom...
Ill create a video tutorial for this tomorrow as many people ask this question in different threads of devices....
