Database Develop

Make a Rom?

I've spent the better part of 5 hours trying to come across information on ROM development.
My question is two part. What resources are there available to learn about creating a rom from scratch or editing an existing (including making the update.zip and signing)
Also, I assume the emulator is involved or at least could be. How do you create the system images that you need to create a custom avd from the zip's that you find roms in?
I have a feeling there's a lot I don't know. Perhaps the answer is in front of my face, but I've been looking for a long time and definitely have tried so please don't just say "use the search fuction" or "google it"

Devs normally don't like to share the info but there's a guide here:
http://ctso.me/2010/02/building-an-android-rom-–-part-1-5/
But the info is in other places to the google-android page might have some info to. You must be using a linux OS to actually build anything, windows is a no-go...

Quick and helpful, thanks!
Luckily I did just put the latest ubuntu on my laptop.
If anyone else wants to chime in with some helpful resources please do!
If some annoying little 14 year old made a hero rom, it can't be all that complicated.

He was just lying, he spammed various threads while talking about other devs.

first he's 14 then he's 12...next he'll be a spoiled 8 year old. you just watch.
I'm glad I checked this post. I was curious about ROM developing myself. Thanks for the post.

Is it me, or does that guy have more then one account...

At the risk of taking this further off topic... what guy?
But really my main concern is how to make a rom so, any other help from anyone would be good. Thanks!

Bump?
I'm sure somebody knows something

If you would like to compile android source code (create a rom from scratch) the best place to start would be:
http://forum.androidspin.com/showthread.php?t=2004
or
Chris Soyars' blog: http://ctso.me/2010/01/building-an-android-rom-part-1/
OpenEclair github readme: http://github.com/openeclair/android
Official AOSP Guide: http://source.android.com/download, http://source.android.com/download/using-repo, http://source.android.com/documentat...ding-for-dream
Instructions on creating and signing update.zip files can be in a few places herre on xda. Check the themes section I'm pretty sure I saw a few there.
Also, I assume the emulator is involved or at least could be. How do you create the system images that you need to create a custom avd from the zip's that you find roms in?

Install the rom on a handset & do a nandroid backup. It will produce the img files you will need for the AVD

Dude, you're awesome, thanks!

Root and Know What?

I am Newbie and I Just Rooted my phone.
So what can I do Know?
I did the Wi-Fi Tethering and Worked.
I downloaded Metamorph but didn’t found any Themes.
I want to delete Sprint Apps, and don't know how to...
Want to change the lock screen, but without changing the ROM...
Anybody could come with a List of what people can do, know that the phone is rooted.
BTW I am Running Sprint 2.1

Click on the link and download Fresh Kitchen.
You can create a nandroid, remove the bloatware, change the current lockscreen, create your own rom.

Welcome to the world of root!
While what Dave provided is in no way bad or wouldn't help you accomplish what you want, I suggest looking up adb commands.
Check out the main wiki thread in my sig. It will have a thread called "How to Remove Stock Apps, etc."
Once you have looked a little there, post back and let us know if you can't find some information, and we'll gladly help you out.

I've got to agree with Riggs, while Kitchens are nice for people who know what they're doing, I'm a firm beleiver that people just starting out should use ADB as much as possible.

[Q] Searching for an automated way to deodex and zipalign

There are some ROMs around that are deodexed and zipaligned. The ROMs around here unfortnately are themed (not to my taste) and/or have removed Samsung stuff that i use. I want a nearly untouched FW (i remove a few Samsung apps on my own).
So i'm searching for an automated method (that can also be used for future FWs) to deodex and zipalign the files of my phone (maybe only some binaries or java applications and a batch file).
I can manage to pull/push all files from/to /system/app and /system/framework but i'm not able to do the rest...

Also very interested in this. Or a clean kitchen or a how to on making a kitchen to mod our roms.

I just wanted to create a thread about MODIFYING / CREATING CUSTOM ROMS FOR THE i9000.
Does anyone know how to modify (for example, Tayutama's JPM Full ROM) ROMs?
I googled and just found some HTC ROM HowTo's.

Check my signature for all the tools u shud need in terms of deodexing, editing apks, creating signed update.zip. Thats all you really need i think :\

A zipaligner is missing.

yes that'd be perfect! trying to optimize my device myself here too.
if there's no automated way could someone be so kind to post some instructions as to how?
found some stuff on the g1 forums but i'm not sure if it'll work...

Quite an old topic, you'd be better off just creating a new thread.

[Q] Adding Libs to roms..

As the title says - Adding libs to roms, can someone point me in the right direction? I have been a member of this forum for a while, just not a posting member, I now feel it is my time to add something back to the community, is it as simple as adding it to the rom whilst flashed to an X8? Please help me, maybe I can bring something back to the community..

maybe developpers little bit bz rite now..
what i can advice you is..
just flash the room and then use 'root explorer' to play with lib
make sure your phone rooted
peace!

Thank you, I will try that, I am wishing to work on a ROM and get wifi, 3G and such working, however I have tried using ADB to push the libs but I don't know if it worked or not..

I want to make the whole sense rom work, BUT I can't access the system files without having the rom installed which is pretty gay.. I need some way of accessing it in the .img format which then I can flash to my phone to test... mshhh... plus I'm not quite sure which libs will work (ofcourse when I find out I will seek permissions before uploading the rom...)

To open .img you could use Winimage or Poweriso or something similar.

Already tried.. comes up with an error stating about unknown formats..

you could try opening it with winrar. maybe that 'll work

Already tried, same problem... I found an unyaffs2 program compiled for windows which allowed me to extract the image I just need to mkyaffs2 it back to img then maybe I can get it working BUT I need to be in Linux and I can't be bothered making a VM at the moment...
Maybe someone can help me with this? We could work together to make a fully working sense rom... come on people.. someone who wants this must have a bit of knowledge on the subject...

Tutorial

Can anyone point me in the right direction where I can find a tutorial for how to make roms for the Samsung galaxy s6.I'm a beginner so I need to know which files as well as how to use them. Any help is greatly appreciated.

It depends, stock or aosp? With a stock rom just download one already made and a untouched stock system then figure out how the developer did what he did then make your own with the knowledge you gained. You will probably need a kitchen to make the installer script because that is a pain to do yourself. Aosp is a whole different bag of marbles but cyanogenmod has a good tutorial on how to do it and that knowledge will transfer to non cyanogenmod builds as well. If you are not competent with Linux learn that first. I would suggest arch Linux because it will force you to learn the command line. cygwin won't compile aosp so don't even think about trying that shortcut.

I appreciate your feed back and I want to start with stock and go from there. I've programmed before which was done by writing all the code just not android. That is why I'm asking for tutorial to show me what, where, and when. It is not something just because I'm curious I really want to get involved and see if it is worth my time. So I need to know as much up front as possible which once I understand that then I can go forward.

Not much coding in stock, more like shuffling stuff around. The closest thing to programming with custom stock roms is the edify script (installer script).

What I mean is command line will not be a problem for me since I have written code before which uses a type of command line. I'm looking for the tools needed to do the roms you say something about kitchen and what else? Maybe I'm just making this harder then I need to but I'm just trying to learn how to make roms of my own and need a place to start.

Yeah I don't know of any tutorials, other than what I suggested in my first post your best bet is to just jump in head first and use google when you get stuck.

If you go to infamous rom developments webpage which I can't post here because I will get in trouble. He has a full step by step guide how to do everything from stock roms to aosp and even kernels.

I went to check out that guide to make sure you are going in the correct direction and found it wants you to use the old dsixda kitchen which has been abandoned. Use archi kitchen instead http://forum.xda-developers.com/showthread.php?t=2597220
Try to use the kitchen for compiling the installer script only, you'll figure stuff out faster that way.

This is a basic question, but for the life of me I can't find a tutorial in how to deodex system files for the S6 that actually work. Tried a few but afterwords when decompiled they don't show smali files. Anyone have a way to do this?
