[NOOB] What shall I learn? and how to start porting newer android?

Right, I wanna start modding my phone now that i have some spare time. Just two things I need to know:
1. What code languages do I need to know?
2. How do I start porting a newer version of android to my phone when I know the languages? (any tutorials or guides or anything?, my phone doesn't have an unlocked bootloader so I know this will be a problem, but it still can be done)
Please just take two seconds of your time to help me
Thanks in advance

C'mon guys, all i wanna do is learn. is there anyone that can help me??

As far as I know, you would want to build Android from source. In your case, try looking at the CyanogenMod source.
There is also a wiki entry on the CyanogenMod website, showing you how to build CyanogenMod from source.
Knowlegde of C/C++ and Java will prove useful, as well as any knowlegde on Linux.

[GUIDE] Custom ROM development for the rest of us [In Progress]

*** THIS IS NOT JUST ANOTHER EFFORT TO CREATE YET ANOTHER CUSTOM ROM***
Though Android is opensource, a lot of things are unknown regarding ROM development/modification. There are many custom ROMs available for Galaxy 3 (and also other phones) and lot of people are flashing them and making their phone more responsive, productive and faster; but very few people actually knew how to go about developing the ROM.
What I intend here is to find out and document correct way to build ROM for our favorite Galaxy 3, which is very popular in India.
The goal will be to develop the ROM from Android source + Drivers from stock ROM while documenting the process so that large number of people can contribute to the development.
I will shortly update the posts with what I have done.

looking forward to what you come up with
Making one aint difficult keeping it bug free might get sometimes

Thanks rudolf895
I have experience in Android SDK and NDK development, but I am a noob when it comes to ROM development. Thats why this effort.
I have fetched android source using repo as well as I have also downloaded source for I5801 from Samsung open source website. After this I will look into extracting drivers from stock ROM and successfully compiling it for Galaxy 3.

hehe, cant wait to see what you come up with, sounds promissing btw... i am also willing to help whereever i can, whereas this wont be too much in this case i guess.
good luck and thanx...

TY ..!
Thanx alot
This would be really helpful to alot of members here

interesting ! waiting ....

I applaud your thread, I myself was thinking about such a concept.
I wanna help, but I cant do that much (basic knowledge of C and basic/little knowledge of linux and adb).
I think first there should be a list of basic stuff. Like compiling the sources, extracting factoryrfs and co from your phone etc... Sometimes if you wanna start doing something and you dont know the basics you get scared off because of their apparent tremendous lack of knowledge.
I'd probably start dabbling if somebody told me how to compile the sources.

can you also specify your work environment, toolchain and such stuff, so anyone can start from zero? there is a kernel building vm image with all tools by sztupy somewhere on the forum that is eventually of interest, and there is also an extended version containing eclipse and some more tools for full android development:
http://forum.xda-developers.com/showthread.php?t=882010
hope this helps somebody...

Did you try using it? I think the scripts are specific and cant be used by us (without altercation)

no, i have absolutely no idea of kernel compilation and all that advanced stuff, but i guess it can be adapted for our use

Yup...me too in waitin line...Now i can say i dint made a mistake by buying it...

maybe you can create a ".tar" package including all those files.. .tar is flashable in odin..

[Q] How to create my own rom.

Hi,
I'm following the Nexus S Android Development for 6 month now and Rom and Kernel flashing is a a real addiction for me (I flash everyday).
And, since the beginning i want to create my own Rom.
At first, I want to build one from another one (Cyanogen or another).
So, If someone can give me tutos, tools, tips and advices, I'll be very grateful.
Thanks to everybody, waiting for your help.

Hey you know i find myself sharing this exact interest as you. Let's collaborate and learn this Create A ROM Project

Notice to see the motivation to create a new ROM.
How good are your Linux skills? If you want to do it all properly I suggest you try and build your own AOSP ROM first (from the Adroid Open Source Project).
This is the place where Google publishes the Android source code files. Actually the site is fantatic and guides you through the entire process, but it does require you to understand the basics of the maketools in Linux.
Once you've been able to compile the source, you'll actually have a perfect stock ROM version of Android. Then, you can start doing advanced things to it. Add a different Kernel, add apps, install tweak scripts etc etc etc, the options are endless.

Thank you again.

oh thats great

Dont know where to start

Hi every one I dont know where to start i want to make my own rom from source,build it,modify it etc.But i dont know where to start.I know how to build rom from source(learned it from the tutorial on source.android) but i dont know what do those codes mean.i searched on google but cant find an easy tutorial.If i build rom from source how do i make it work on my phone.How do i FIX bugs on my roms,modify it Help please

Check out the chef central section under android. There are a lot of great people working on making development accessible.
For a pure AOSP ROM you are going to have a bit more work, but be rewarded in the end. There is also cyanogenmod and other custom distributions you can build from source and modify.
If you are familiar with C and Java programming you can dig into the actual development more by writing apps or changing source code. If you don't you may want to start on that road. Other wise you will be basically cutting and pasting from everyone else, which doesn't get you any credit.
Themes are also a good place to start. There are lots of good guides in the theme section and people are willing to help if you ask nicely and appropriately.
I have done a bit of this foot work and come to the conclusion, I need to learn programming then come back to source. It is overwhelming to take on an entire operating system in a foreign language, especially when that language has to be perfect to function!
Good luck in your endeavors. Feel free to hit me up for the little knowledge I have!

But! where to learn
First i want to learn the basics of Rom

are you familiar with Java, C and C++? These are going to be very useful in understanding the "codes" as that is what they are written in. You are also going to have to build AOSP specific for your device, which will require adding your device to the device tree and extracting the necessary drivers and files that are specific to your device. Cyanogenmod has many devices already added to their github and you would simply clone the folder for your device, then build AOSP source and issue make using the device specific folder.
THIS is a helpful tool, and yes it will compile pure AOSP as well.
THIS is also a very helpful tutorial, and you can modify instructions to work for Gingerbread.

If you just want to learn to build and modify the source start with Cyanogenmod build from their source first. You can also build the kernel if you choose but that is a bit more complicated. After you have both of those building without errors then start making changes that you want to see.
The CM Wiki has some good info http://wiki.cyanogenmod.com/wiki/Building_from_source

Creating a rom based off CM(Galaxy S4), How ?

A bit of infos before starting this thread. I'm using a Samsung Galaxy S4 Canadian, I have a high end computer(maybe that helps for coding,stuff like that) and I have "medium" knowledge on rooting/flashing,etc. I am a great designer, well for myself, I think i'm good. So I can edit or create icons and themes for new rom!
I say medium, because the only thing I really know about this kind of stuff,is rooting,flashing,installing roms and pretty much that honestly.
I already downloading the Android SDK to test those custom roms i'd like to create. I thought of doing like a couple of guys on here, using the CM Source? and just adding stuff,etc.
--
What i'm looking to do, is creating a rom based of CM for the Galaxy S4 and just in general a little side project for myself and adding some infos in my head; Some may laugh because of the lack of knowledge, but hey! we all started somewhere
I'm asking the community of dev's or just users, do you have some threads or some stuff to download to "Start" this project ?
Some things I should read before, I won't test rom's on my phone as it's a daily phone, i'll use the emulator instead(AVD or SDK) and i'm already searching on how to run it.
If you have any useful youtube videos i'll gladly accept them
I found a tutorial on how to build a rom but for the Nexus 4, I guess it's the same process but different sources ?
I'll search for the sources of Cm for the Galaxy s4 but if anyone reads this thread and knows where to get it, please link me!
Thanks to the community, this may also be useful for other users. Thanks!

Okay, I will help
1st off, let me teach you some basics.
1.) You cannot test roms on the android sdk, the android sdk has nothing to do with roms, its for building apps and java programming. It will not help you with anything if an issue goes wrong in a rom, well only the adb (android debugging bridge) for taking locats.
2.) You cannot compile a rom on windows, only linux, preferably ubuntu. So you need to just download cm11 for your device and extract the rom zip.
I will tell you more later, but its like 1pm here Goodnight
