I know this is a really noobish question, but i was really curious, and im really trying to learn as much as i can about smartphones and rooting etc.
So my question is "How can cyanogenmod make roms" for example I own a G2X cyanogenmod apparently has an ICS build ready to release, but how do they do that without an official release or something from LG because LG doesnt release the source codes. Do they make their own source code, or something? If you could answer this and explain it to me it would be much appreciated. Thanks!
They don't need an official release from LG, because CM is based on stock android for which sources (ICS included) are available from google.

Am I the only one who is unhappy with the slim pickings of ROMs that are available for the SK4G?
Does anyone know anything about an ASOP ROM?
It's AOSP (Android Open Source Project) and you're not the only one not happy with the current SK4G options. I personally want MIUI or CM7, but seeing as we're currently stuck with Froyo, we'll have to see what the devs can cook up.

For future reference, questions go in the General forum, not the Development Forum.
As for AOSP or MIUI, I know that AyoTeddy and Revolution are currently working on separate MIUI roms, and for AOSP, I'm working on that, but not sure exactly what you want from AOSP that's different from what we have?
If you are unhappy with the selection of ROMS here, you are always welcome to make your own, android is open source for a reason.

If they want the real miui we will need some sort of aosp gingerbread to start with and a custom CM7 kernel or something.. Since we dont have either yet I guess we'll have to make the best out of what we have now like we have been. But those wanting a taste of miui may like what I have planned for my next release.

And so anticipation had set in, i can't wait ayoteddy. im very excited. SMX was great, and SMGC was awesome, and now with this? whewwww. think i better go lay down, lol.
I'm also interested in porting CM7 to Sk4g cause I'm used to when I had G1 and now I'm using Sk4g without it.
I have programming skill and understanding of linux architecture. I've read about android architecture and AOSP and how to build Cyanogen from source. I'm running a tech firm (about 30 employees) - we are developing games that's why I don't have enough time to port it faster but I'm going to do it in a month or two.
So, I need help from experienced dev for android who is willing to build AOSP rom for Sk4g.
Here is what I'm going to do:
1) I'm gonna try to build Kd1 rom from source (there is an opensource code from samsung) and flash it to my Sk4g
2) Change the platform in original source to AOSP 2.2 and remove all TMOBILE apps - then build and flash
3) I'll try to find all hardware specs of the phone to compare with other samsung devices. It can help to exctract proprietary drivers of the phone. I think that the drivers are commonly the same, but I need to identify it.
After that I'm gonna upgrade to AOSP 2.3 but I don't have enough knowledge right now. Can some experienced devs answer the questions:
1) Are the linux kernels of AOSP 2.2 and 2.3 identical?
2) Can I use device drivers from 2.2 on 2.3?
If someone is interested in this project - please let me know and let's start the job. I think that my progress wouldn't be fast due to lack of time.
Thank you for joining the Sidekick 4G section , & we welcome you but if you want you could pause the game's for the ROM if anything & Question 1 is a no & Question 2 no cause they have to be compiled with the 2.3 kernel .

Revolution, thanks for relaying my responses.
jmpz, I tried building the source before, but was unable to build it completely, but that was possibly because of some errors with my dependencies. The kernel compiles fine from source, you just need to pull initramfs, or you can get it from Dr. Honk's github.
Thank you for your answers.
So, can anyone enumerate the list of drivers which we should extract from kernel?
I can name these:
1) Keyboard
2) Mic
3) 2 speakers
4) buttons
5) front camera
6) rear camera
7) trackpoint
8) lcd
9) digitizer
10) 3.5 jack
Please correct me and add missing
If I understanding it rightly the key problem is getting proprietary drivers from the kernel. Right?
nope, the key problem is trying to build the system entirely, without any errors, which may be easier with someone following a stock designed build environment. I don't use Ubuntu which is what has the listed dependencies for every tutorial I can find. You can get the drivers out of Dr. Honk's voodoo kernel ramdisk here: http://forum.xda-developers.com/showthread.php?t=1145139
There shouldn't be any problems if you just set up a build environment following the directions in any of the tutorials, then add the platform from the samsung source.
I'm a linuxoid - so these tutorial are for me. Thank you for the link.
By the way, drivers are in Linux Kernel, so I don't think that I need to use Samsung Platform from the source. Instead I wanna use platform from AOSP or Cyanogen. Correct me if I'm wrong.
I think that grabbing drivers from kernel source from samsung would be enough to build the rom.

I 100% support your efforts. I want Cyanogen on the SK4G badly, but I'm not sure what kind of help a non-programmer like me could do, but do have some experience with flashing phones and such, so if there is anything you need let me know.
If you do get rolling heavily on this, I'd be willing to donate monetarily to your efforts.
If anyone can get CyanogenMod 7 on the Sidekick they would definetely get a donation from me. Id be thrilled. Glad to see its going to be worked on.

I am building an aosp ROM for the galaxy player 5.0 as an independent study at my school. I have the stock kernel for it that I extracted out of an odin image and I was wondering, do I have to build aosp around the kernel because I heard aosp kernels aren't good with the drivers and I need every function to work. I have found many tutorials for aosp and I am not going to use Googles since I can't understand that as much as other ones on the internet. Can someone enlighten me on the subject so I'm not going to fail, its due by january and I am still on the fence about whether I can do this. I just need some guidance and not to have somebody do it for me.
Hey guys, I have been looking for a jb miui ROM for this device and i cant find one, i know there are some ics miui ROMs, but i would really like a jb miui ROM.
There is one for the vibrant, can I use it for my Galaxy s 4G or can anyone port it to our device?

Just because there are some homebrew ports doesn't mean that MIUI is 4.2 yet.

Why does it matter ? We use unofficial ROMs anyway...
sent from me
That's like saying that since a car, airplane, and weed-whacker all run on gas, you should just put the same stuff in each. Actually, the unofficial ROMS is a more tenuous connection than my gas connection. It's more like saying that since a bullet train, horse, and diesel bus all run on fuel, the fuel which goes into each shouldn't matter. It's all fuel.
Hey, you could (please don't) use an unofficial Vibrant ROM too. That's unofficial. What's the difference? The difference is that it won't work. And might brick your phone. That's bad.
Our only current Aries kernel is 4.2.2 and still has issues. MIUI is still 4.1.2 and would introduce an entirely new set of issues tied into GPS, Bluetooth, and so forth if/when a 4.1.2 Aries kernel was compiled. Does that make it impossible? No. But it means that as the build impetus - when MIUI is 4.2 - has not happened yet... it's not a great use of time yet. Unless one of the devs wants it. In which case, MIUI being not-updated is something they don't need to be hammered over the head with.

4.2.2?
Port. If YOU see source linked from that page so our devs could actually do something useful to build that...
Hi Theraze
I have to disagree with you.
Port is not a dirty word and most of our ROMs are actually ports and not built from source. Furthermore, MIUI ROM is usually ported and not built from source and only recently did Xiaomi open their sources for the public. Even more than that, both MIUI versions brought to us by Beast were ports from Nexus and not built from source.
Now, regarding the incompatibility between kernel & OS - if it works on Nexus, I assume the adjustments were made, so one can enjoy both 4.2.2 & MIUI benefits. There is no logical reason why it couldn't be ported to our beloved device.
sent from me
I'm not saying it can't be done. I'm saying that our build-from-source dev who asked you to let him know when it hit 4.2 hasn't had his request met.
Does that mean that someone (him or another dev) CAN'T port it? Nope. But it makes it a lot less likely that air can just pull the source in and compile it using the Aries bits if the buildable MIUI is still only 4.1.2 and our Aries is 4.2.2 instead.
Again, I think we're agreeing on the general bits... yes, this is possible. But airfluip1 asked to be notified when buildable MIUI was 4.2.2 and that's when he said he'd build it. Not port it.
I don't care if a ROM is ported or built from source.
I will try to play with porting it myself.
So, Since the Cyanogenmod source is so big (I heard that it has 19GB), people like us who have gay as slow internet have no chance of even trying to cook a ROM for our unsupported devices.
Since I can't download the whole CM source and I see awesome ROM's out there, I Ported one ROM called Cyanfox (which was made for Samsung S2 i9100) to Samsung Infuse 4G using Beanstalk ROM as a base. I followed a guide which asks me to replace some folders and edit some files. It was walking fine. Then came an update to both the ROMs, Thinking that cince it is a update, it will have the updated apps and source, I tried porting them again but this time Beanstalk updated ROM as a base cause a bootloop while the Beanstalk old ROM works fine as a Base ROM.
Now what I don't get is, why is Beanstalk new ROM not working as a base? (Since the new Beanstalk ROM will have updated Source, I want to use that ROM as my base.)
And the second question is, what files does actually matter when you are Porting or cooking an Android ROM? (I mean like windows works on all kind of PC's all it needs is the drivers right? The drivers actually matter on windows)
And the 3rd question is can I update the source files somehow without downloading the whole 19GB CM source and if possible how?
The 4rth is, I heard from somewhere that boot.img is the file which separates the phones? Then why can't we just port ROM's by replacing boot.img since these two phone's are from the same vendor and it has likely specs. (Which is not possible I think)
I am really really a newbie to this thingies, I just wanted to clear out these things. Sorry for my noobness.
Thanks!
Hi guys, i am new to android and everything and i have an intention to build a CM based ROM for Hammerhead and i really looking forward on help. I need beta testers and a dev who can help me out, cuz so far iḿ following the rom building guide by this guy called jackeagle, and honestly sometimes it just makes no sense at all so I appreciate any help, don't judge me by any reason.
If you want to build CM rom use CM instructions (there are on cm wiki page). If you want your customizations you need github, fork cm source and modify it.
After it you need to modify local_manifest to use your source, not CM to build rom and voila, everything should work fine.
I know what i'm saying, i've built CM roms for D802, WT19i and some other devices.
