[Q] How to create my own custom rom? - Galaxy S II Q&A, Help & Troubleshooting

Hello, i want to create my own custom rom for the Samsung Galaxy S II.
I searched everywhere on XDA but i cannot find any guide or ressources i can understand. If someone have a topic, a link, or whatever it would be very appreciated.
The must would be a ROM on Ice Cream Sandwich. I don't want to realize something big, i just want to begin to theming defaults applications and perhaps i would continue learning "how to" in the future.
I already have Android SDK installed on my computer.
Thanks a lot! And sorry if there is already a topic like this, i'm a french guy and i'm a rookie on custom ROM, i just know how to root a device, install clockworkmod and install a custom ROM, but i'm not a rookie about programmation and computing.
THANKS!

I would also be very interested in this.
But from what Ive seen, building custom roms is not that easy at all, unless you at the very least have a good amount of linux experience, and other programming.
if not tho, then I'd love to give it a go....even if it was just to grab my fav rom, and change a few things. Is that easy?

As ICS is a buggy unreleased test rom with no release date from Samsung you are in my view throwing yourself in at the deep end .
Possible one place to look is the XDA forum .

Thanks a lot for yours answers guys!
I know is not to be easy to create a custom ROM. But i have to begin to learn how to
I searched on the Android category on the forum and i saw this. It's very interesting. But i downloaded all the SDK, and the APKtool/Manager and i have a problem. I took a ROM named Pure ICS v3 for testing if it work, and when i choose "Extract APK" with the batch file, the xml in all of the APKs is buggy, and i can't modify a buggy xml...
What i can do?
I have another question. For the moment, i'm just testing with a ROM made by a guy. But doing this is concidered stoling people's work. Where i can find a stock ICS rom for the Galaxy S II?
Thanks a lot!

ICS is not released so their are no stock roms .
The leaked Beta /Alpha test roms are in the General section as individual posts per rom .

Thanks a lot!

[Q] looking forward

Hi, I'm looking to buy this phone unit one of these days.
but, most of the units that I see/saw , has gingerbread OS,
is the ice cream sandwich now available ?..
please point me out to a URL of a step by step tutorial
how to tweak samsung galaxy S II , in order to upgrade it to
android 4.0 ice cream sandwich
Thanks in advance
I can't see the point of that until/unless you actually have the phone in front of you
And for the 174,823,904th time, ICS will be released by Samsung "some time in Q1 2012".
Cyanogen have an alpha/experimental ICS build out at the moment which seems to be improving stability/performance-wise every day tho.

I see, so it wasn't released yet, based from your reply.
I thought it was already available.
My objective is, learn how to upgrade, so that once I bought
this unit, I'll immediately upgrade/update the OS before putting
some nice apps from the droid market place.
any tutorials that you might want to recommend for noobs to read ?
How to root your SGS2 & how to flash firmware. Also, some roms have specific instructions (like having to flash the rom twice in order for it to work), always follow these to the letter if they differ.
Best bit of advice I can give you is read. Then read some more. And when you're done with that, read more again. Don't do anything to your phone unless/until you understand why you want to do it and how to do it.
Go to the development section of the forum to read up about the various roms/kernels available for the SGS2 & you'll be able to get an idea of the features/pluses/minuses of each & other users experiences with these roms/kernels.
Then you can decide which you might want to try for yourself.
And before you ask, no I won't recommend "the best rom/kernel", because there's no such thing. Every phone comes out of the factory slightly different (components vary a little), you won't use your phone the same way as me nor will you have it setup the same as me. So you're going to need to do your research first, then try some roms/kernels & see which work best for you.

At the moment, I don't really know what the hell are these roms/kernels you're talking about. But thanks for the link, I'll start digging this to prepare myself for the ICS before buying this cool unit .

[Q] Any tutorials to deodex a stock rooted Rom?

What the title says . I tried google, searching within the forums, but some had their withdraws and were for froyo 2.2. Just wondering how you themers within this thread doing this, I'd hope to bring some goodies here one day
Flash Scrosler's OTA rom. Other than flashing, you can't really do much.
Thanks!

You can always set up the "android kitchen" and deodex the ROM yourself.
I am no DEV, but I did the same for my INC2 ROM

[Q] Looking for help with roms.

Hello there,
I am new to the S2 phone (I will get one at the end of the month from a friend).
I see that there are lots of roms and kernels.
Now what I am searching for is:
Super optimized rom like Tigrouzens rom for Samsung Wave 1 and 2.
Also kernel super optimized.
With other words. a really fast rom (I don't want outdated roms).
Preffered android version:
4.3.X Jelly Bean / 4.4 Kitkat
Also, I don't really know how to install those roms/kernels. So a simple tutorial should do it. Because I once flashed one through odin from pc and not through recovery.
Greetings,
GreekBlood
Go to the development sections (Android Development & Original Android Development), read some threads, try out some roms to find one that suits your needs. Instructions for flashing roms are always on the first page devoted to the rom & always very clear.
Rom recommendations are forbidden here because they're so subjective, mods will close the thread if you insist on asking for them (this is XDA after all, if you're here, it's assumed you like flashing stuff to your phone).

And the best ROM is................................................................. LOL
I predict thread soon to be closed (i am psychic haha)
Oh, sorry.
But it is a bit of a mess here. So many roms, so many kernels.
I'm coming from wave 1 where we have 2 roms and 2 kernels.
Being a newbie, i being in you shoes a few days ago would advice you to start with understanding the fundamentals og flashing and use of the various recoveries out there. You say its a mess because you see so many roms and kernels and you dont know where to begin. Pick one and start and with time you will catch up with the rest. Good luck...modding and customizing android is like a rabbit whole...no end...

Reading the first page & last 10 pages of any rom/kernel thread will give you a couple of things:-
*Instructions how to flash & features
*Some idea of how users are finding the most recent build/any issues
That's a good place to start.
Some people treat this place like a macdonalds drive-thru.

[Q] Where do i get the right android version?

Hi all, I have a noob question that I have not been able to find an answer to.
My main goal is to make my own rom, and there are a lots of nice guides etc for that, but for some reason I cannot find where I'm suppose to download the "stock" android from google.
Where can i download the different versions of android? One should think that there are a rom or at least some files that can be made into a stock rom or something like that?
It would be very nice at least, if I just could download android 5, or one of the others, and then just implement all the drivers for my unit to make it work on a stock android.
Or have I misunderstood something critical here?
Not sure how basic the question is. Stock ROMs are factory versions.
XDA has different flavours of custom ROMs and link to stock ROMs.
Few technical features speak about odexed and deodexed.
Please search the forums and hopefully you can help the community.

Yes I have searched the forums and google, no answers to that question.
Ok so stock rom is from the manufacturer, but google have the "official" version. So there should be a rom or files that can be made into a rom that's clean, from google?
As to the custum roms, I would be better of starting with a "clean one" i should think. And there are no roms that I know of that is working with any of my Minix units, and I would definitely like to get 5.0 on my media streamers.
Odexed and deodexed? Have no idea what is.

First Flash..but i am not sure what rom to choose..

Hi..I did a search but i am completely confused and bewildered by the vast amount of different posts and opinions in threads..so i apologise if this has broken any rules.
Basically i have a stock s3 i9300 (uk) with original samsung jellybean 4.3 rom,I am getting a bit sick of it now (and the bloat) and i am looking to move on to something more appealing..I have already rooted and installed Rom Manager and CWM..i was wondering what the "Best Simplistic dark themed (small footprint) rom" to go for As i want minimal installed size to make the most of my 16gb memory,i dont mind which android version as long as the process is easy and the battery life is among the best available..And of course it is as stable as my current Samsung android rom..
i would really appreciate any valued veteran guidance..many thanks.
