[HOW TO] Beginners Guide to Android ROM Development

- Start date
I resolved my isse and flashed rom perfectly.
I guess when kicthen signs and changes the updater script..thats where it causes a error. I went and signed and ziped the ROM. Went into the zip and switched the files with the original updater script and that did the job.
Thanks for the tut.

Hi,
I try to do this.
but i get an error after:
6.you will be asked about changing the working folders name, at this point it makes no difference so just continue.
->
Adding an update-script ...
NON-YAFFS/NON-TAR FILE FORMAT DETECTED IN ROM
Mounting system.img to loopback device and then extracting files
Error: Unable to mount system.img
Error: No /system/framework folder found!
Press Enter to continue.
->
This is just a stock rom.zip from the last HTC Desire HD update.
Anyone know how this can be fixed?

I'm not sure about first question. As for the second one if ypu vere successful and it didn't show error than yes you have root in your rom.

You will need to find a Alcatel download possibly from their website or their technical website.
For Samsung Galaxy we have Samsfirmware as a source or now Sammobile. So you will need to find an equivalent?
This is for setting up roms from Sources like what I have mentioned. It allows you to deoxex and then you may theme and do/perform modifications your self

Well for editing roms you dont need any special skills just basic android knowledge.Also it's not that difficult once you get a hold on it and it really depends on you how much time will it take to become a great chef.Generaly this is much easier than actual Android development however it's a great place to start.

Is it compatible with droid razr gsm
I read the description on dsixda's page. He says it is compatible with the droid, droid bionic, and milestone. However he doesn't mention anything about the Droid RAZR GSM. Soooo I wasss wonderinnn.....Is it compatible?
Would ask him but he made it clear not to ask him.
Thank You,

I know I will sound slow to some of you guys but....what do you mean by 'compile a rom from sources'

I have been using others' cooking for several years now. I have recently got the fever to cook something up. Thank you for putting this together. I have an LG Spectrum which doesn't have much development yet so maybe I can do some good for that community. I also have a Thunderbolt to learn from.
Thanks again. :good:
Thanks again. :good:
Sure it's possible. Read the original thread about the tool for information about what you need to do to get your device supported. It's some basic setup and you need to define mount point for it and the like.
Thanks for everyone including a noob like me! (I'm now a Senior Member but believe me, I can't even mod framework-res now
)

620This tread is not monitored or updated any more use for reference only
Started this tutorial in the HTC HD2-Nand forum, I think maybe someone
can find it useful
Who is this tutorial for?
- Absolute Beginners like me
- People with little or no programming skills
This is a very basic tutorial!!
Step one: Setting up the Android kitchen
First you will need to set up dsixda's android kitchen
(All credit for the kitchen to dsixda's)
Go to dsixda's thread for a list of supported devices.
Here is a summary of the installation process( I recommend you read the tread first)
1. Before you do anything install the java jdk(find it in dsixda's thread)
2. Download and extract the cygwin_packages.zip provided by dsixda on third post
3. Run the set up(make sure there is no previous cygwin installation)
4. Follow the kitchen read me txt!!!
5) local package directory *must* be the path to the cygwin_packages folder that you just extracted
6) when it shows all the package names, go to the top and select "all <-> default" until it changes to "all <-> install" (you must click on the arrows)
7. Run the cygwin at least once and close, now you will see a folder inside the cygwin installation like this: Home\your user name\
8. Download the kitchen and extract to the home\your user name\
9. Rename the dsixda-android-kitchen-*** folder to just "kitchen"
10. Now your ready to run the kitchen type:
Code:cd kitchen(enter) ./menu(enter)
11. If you did things right you should see this:
congratulations!!Step Two: Setting up a working folder1. First our folder structure should look like this:
2. Inside the kitchen it should look like this:Code:cygwin folder/home/your user name/kitchen
3. Now we need a rom to work on, for this tutorial i will use my own rom but you can use any hd2 rom. Place the original rom zip in the original_update folder inside the kitchen.
4.run the cygwin.exe again type:
5.now enter option 1, enter again. You should see your rom listed, choose and enterCode:cd kitchen(enter) ./menu(enter)
6.you will be asked about changing the working folders name, at this point it makes no difference so just continue.
7.you will be asked to convert to update-scrip do it and continue
8. Now you can view the roms info
9. congratulations you have a working folder!!!
Step Three :change/modify/update!
First I will be covering basic changes you can make to your rom, later I will be adding more helpful hints.
Adding/removing applications
1. Go to the working folder where you extracted your rom, inside you will find:
or
2. Then go to "system/app" inside this folder you will find all the rom applications(apks) you may also find some in the data folder if your rom has this folder.
3. Copy, replace, and change any app(apk) be carefull if you dont know what the apk is do not delete!!
4. Congrats you have modified a rom, if your ready and want to see if it worked skip to step four to buil rom from working folder.
Adding new boot animation
1. Just replace the bootanimation.zip located in "workingfolder/system/media" with the boot animation of your choice.
here is a sample of my bootanimation to try.
Edit the gps script for your country/location
1. In the workingfolder/system/etc/ you will find a file named gps.conf, you can
edit this file with notepad++ or even word.
2. using the right gps script in this file can speed up gps lock, you can
find some from angeldeath, download extract and replace the gps.conf.
Changing the default wallpaper
1. Be very careful doing this, do not edit,delete or modify an apk without knowing what it is or does.not all things are as simple as copy and paste.
2. go to the workingfolder/system/framework/
3. Install 7zip and open the framework-res.apk
4. With in the framework-res.apk with 7zip go to "res/drawable-hdpi/" and look for the default_wallpaper.jpg. You can extract modify and replace with new one.
5. Make sure its the same file format and image dimensions.(in some roms you can also modify the default_lock_wallpaper.jpg)
MMS Fix for T-mobile
1. *I Have only tested this on MIUI Roms*
2. Go to "workingfolder/system/app"
3. Find MMS.apk
4. Right click and open with 7zip
5.Inside mms.apk go to "rex/xml/"
6.replace the "mms_config.xml" with this "mms_config.xml"
modifying build.prop
"build.prop" is a file that contains various system-vital "parameters"
Some can be modified with little risk, some can cause havoc. So Please do this Carefully!!!!!!
1. Locate the file "workingfolder/system/"
2. Open with notepad++
There is several simple changes that can be done, I will start with some and add more later.
LCD Density
1. If you dont know anything about this topic Here is some info to get started
2.Locate this line inside the build.prop "ro.sf.lcd_density=240"
3.The only value you will modify is the "240" to your preference.
Difference is simple and visible!
Update Kernel From update.zip
Note that it's not always as easy as copy and paste
1. Extract you kernel_update.zip
2. Copy and replace the extracted files to the corresponding folders inside your finished ROM
3.Start with the boot folder
3. Than the system folder (there might be some libs and modules associated with the rom)
4. Another helpful hint is to open the updater-script
to see if your kernel requires you to delete anything for the kernel to work correctly.
sample script:
Code:delete("/system/ppp");
-there are several other options provided by dsixda's android kitchen for that I recomend you go to the tread and read.
Step Four: repackage the rom
Now that you have made some changes it's time to test!!
1. Run the kitchen and enter option 99 - "biuld rom from working folder"
2. Choose mgldr or clk
3. I recommend that you go with all default options until you get more experience with the kitchen.
4. When its all done you will find a folder inside "cygwin/home/yousername/kitchen" called output_zip
5. Inside the folder is your new rom ready to be flashed and tested!!!
UPDATER-SCRIPT
I had a couple of request on how to get custom txt during the ROM installation in CWM,
the updater-script basically tells CWM what steps to take during the installation(flashing rom).
If you don't have any experience please don't edit anything other than what is in this simple tutorial.
1.First once you have your Rom ready in .zip format, Open with 7zip
2.Go to META-INF/com/google/android
3.Extract the updater-scrip file
4.Open with Notepad++
5.Any text that would appear during the CWM install should be in this format :
Here is the requested 3d MIUI LOGO for example:Code:ui_print("Put your text in HERE");
6.Add your text start at top and save,Code:ui_print(""); ui_print(""); ui_print(""); ui_print(""); ui_print(""); ui_print(" ___ ___ "); ui_print(" /__/\\ ___ /__/\\ ___ "); ui_print(" | |::\\ / /\\ \\ \\:\\ / /\\ "); ui_print(" | |:|:\\ / /:/ \\ \\:\\ / /:/ "); ui_print(" __|__|:|\\:\\ /__/::\\ ___ \\ \\:\\ /__/::\\ "); ui_print("/__/::::| \\:\\\\__\\/\\:\\__ /__/\\ \\__\\:\\\\__\\/\\:\\__ "); ui_print("\\ \\:\\~~\\__\\/ \\ \\:\\/\\\\ \\:\\ / /:/ \\ \\:\\/\\"); ui_print(" \\ \\:\\ \\__\\::/ \\ \\:\\ /:/ \\__\\::/"); ui_print(" \\ \\:\\ /__/:/ \\ \\:\\/:/ /__/:/ "); ui_print(" \\ \\:\\ \\__\\/ \\ \\::/ \\__\\/ "); ui_print(" \\__\\/ \\__\\/ "); ui_print(" "); ui_print(" "); ui_print(" "); ui_print(" "); ui_print(" ");
then replace with new updater-scrip
congratulations!!
Just want to thank XDA Forums for giving us this space to play learn and share.8Awesome I had zipaligned as one of the first steps of creating my ROM instead of doing it at the end. That could be causing my problems. I'll check it out now that I'm not at work. What do you mean by replace bash by the original bourne shell? Also what are other ways to create custom ROMs? Can it be done in eclipse for example? Or does it need to be built through the command line interface using the android SDK? What are my other options for developing my own ROMs that doesn't mostly automate the process like the kitchen? Of course I'll continue using the kitchen until I have a better understanding of how things work, I'm just asking for future reference.
Thanks.:good:
There are other ways...like right now you're a chef(using the kitchen to cook/modify ROMs)..not a developer(who uses source to compile his own ROM...e.g AOSP, Cyanogen etc)...
I'll give you a link to 2 videos that taught me how to do it(the developer style)...but I'm not currently building ROMs due to Harddisk space issues..
Here's the links :
Part 1: http://www.youtube.com/watch?v=1_H4AlQaNa0
Part 2: http://www.youtube.com/watch?v=rFqELLB1Kk8
PS: I hope you wont have problems with his accent...just listen closely and it'll be simple to understand!
PS2: Bourne shell is the "sh" that you replaced by bash...try reverting back to sh...and at this point *create a backup*...if after the zipaligning..all works well..cook your ROM..keep a backup of the working ROM too...and then add bash to ^^^^^ this backup..and try cooking another one if you want a bash version only..
Check this thread..its not for your phone...but you can take the idea from here: http://xdaforums.com/showthread.php?t=1090834
PS3 : Eclipse cannot be used to create ROMs (As far as i know)...You can however create apps for android in eclipse...heres a tutorial for that: http://www.vogella.com/articles/Android/article.html
Hope i helped! Dont forget to hit thanks if i did!76Awsome guide.
I hope someone would like to help me make the galaxy ace compatibe with the kitchen.
