*** 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.

Can anyone help me convert system.img and userdata.img file into files flash-able by ODIN?
Thanks

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...

Hi All.
I am Abhisek and I am trying to build CyanogenMod from source for our Micromax A70.
Micromax A70 is quite popular in India as a budget phone, but this device is stuck with Froyo. No more updates from Micromax as well as no kernel source from Micromax. So I am trying to build CyanogenMod from source for Micromax A70.
I am choosing CyanogenMod over AOSP as CyanogenMod supports more devices and have many patches over AOSP. So building CyanogenMod will be easier than AOSP. If successful, I will port a Oxygen/AOSP build.
I was about to give up hope until I found out how to enable ADB on Micromax A70. So I have successfully enabled ADB & obtained the system dumps. Now I can start on this project.
Current Status:
1. ADB is working perfectly.
2. System dump obtained.
3. Hardware info obtained.
4. Firmwares obtained.
5. CyanogenMod sources download in progress.
6. Currently creating the device & vendor folders.
I will keep the progress updated here. Lets hope for best.
P.S. Mods if this thread is inappropriate or in wrong forum, please do the needful. Couldn't find a better place to post this.

I will provide the adb tutorial in case anyone is interested ( that is how I got the system dump ). All credits go to mastermind1024 of androidforums.com. It's not my work, so if you have to thank, thank him. He is the one did all the adb working stuff. You can read the original post Here.
Update:
mastermind1024 is here on XDA. You can see the tutorial Here.
For me, I have to manually run /sbin/adbd from Android terminal emulator to get a working adb connection. You also have to give permission for adbd in SuperUser. FYI I use ubuntu.
If you need the boot.img & recovery.img You can follow the tutorial Here

Yes AFAIK if I succeed, this will first GB ROM for A70.
------------ edit -------------
I have tried to run ADB with root permissions. It works, but somehow adb remout does not work.
P.S.: I found the problem, the system was already r/w.
I would say NO bcoz i m from a secret team and we had ported GB to A70 and touch doesn't work in any of the Ports
Moreover u will wonder that touch doesn't work in Android 1.5,1.6 which i had ported from HTC G1 also it doesn't work in 2.1 which i ported from Micromax A60
So we need to build ROM from source which u r doing. Moreover that is not enough because as soon as sync completes then we need to enable touch drivers in BoardConfig.mk

Great!! I had no idea A70 had a GB port. If you can share the details It would be easier to compile for A70.

This seems like a binary port using kitchen. Right?
Binary port?
Its ported using kitchen which involves replacement of kernel.
And when sync completes, inform us here,a we will make two roms.
One with unchanged boardconfig.mk and second with modded boardconfig.mk
Sent from my Micromax_A70 using Tapatalk
Replacement of kernel includes replacing binary files including so ko and firmware files. Which are all binary. Only recompile includes a output which is not binary replacement.
Download is still at 93%. I will come back when its finished.

I am also at 91% since a week..i am getting fatal errors on sync now n then..project downloads upto abt 86%(abt 650mb) n then I get error...i had to do all again..still no luck.i wish i can finish it tonight.we (me,varun,akshay) eager to lunch rom from cm source as we have hope that changing boardconfig will give us working touch.let's see.
extract-files.sh
I have completed sync & also made extract-files.sh
I want others to examine & complete it if I have missed something.

the script doesnt have adb pull for the binary akmd2.without which sensors wont work .
and in a70 there is also a file called Focal touch.kcm and this is used by the kernel at boot i checked in dmesg .
so add this two files two ..

JB 4.2 on MT6577?
Even with the rom and kernel, you will need ALOT more to work with.
And did you forget Mediatek is Closed Source?
Wish you good luck, you will need it !

I actually read it
My reply was based in, what use can u actually have for JUST **hint**hint** the base system and Kernel source code?
Being the rest Closed Source, there isn't much you can do with JUST that.
Don't take it personal, i just hate these Comp. that dont comply with the Android GPL License.

Hello.
This thread might seem to stupid but none the less. Anyways, I was thinking that due to lack of developers we don't have cyanogenmod.
The last proper developer we had was varun.chitre15 and he left due to getting a new device, he did not have micromax a110 which might have been a reason that he wasn't able to fully develop cyanogenmod.
If the micromax forum community here would unite and donate to a developer who can develop cyanogenmod for us, we might just have it on our device. The donation would be so the developer could get the phone Micromax A110 and develop cyanogenmod.
We can donate via paypal. Even the smallest of donation could help. So what are your thoughts on this guys?

And if you have already found one then let us know..

The first thing the developer to whom you are about to donate the device will ask is 'working kernel sources' and availability of MTK RIL sources. Without them even Steve Kondik won't be able to do anything

Now you are telling this huh !
When you were developing cm 10.1 you were on the edge of booting it but you discontinue it, and according to your statements every driver can be ported except RIL is that correct.
And you also told that, you can port RIL too if you have a device. So i think Steve Kondik can build cm 10.

You are making a mistake in understanding terms 'booting' and 'working'
Even if I had to continue, I would have to stop at some point where development won't go any further. Making the build booting was never an objective.
Even if some miscellaneous drivers viz Bluetooth, Wifi could be fixed, I cannot imagine a phone which cannot do basic SIM based operations, and hence working on the same was out of my sense. So, the point that none other than Mediatek can build an Android build remains to be valid.

better you understand first step by step to prepare and setup build environment, u can find many guide how to build android from source, u can read some reference from here
Do i need to add kernel source in manifest file??
Try to build CM13 if u succeed then try and build CM14 it will be much easier and yeah CM14 will be much better but it will be harder for now to fix bugs. But i am not sure about that. Good luck.
