Question about porting a rom

Sorry in advance if this should be in Q&A (mod please move if inappropriate) but my question has to do with development so....
Anyway.. was wondering if anyone could point me in the direction of any guides or helpful threads that would help teach me how to port a rom. I am wanting to start to learn how to make custom ROMS and figured this would be a good place to start as the heavy lifting has already been done by the real devs...
Specifically looking to port lets say a nexus S rom for use with the NS4g for now.
Thanks in advance for any help you can give!

I was wondering the same thing. It seems like so much good is coming from the Nexus S section, that I would like to help bring it to the 4g side.

Yes, I know. Me too as well, but there's no guides on porting or I just can't find any. If anyone knows any guides on porting, point us fellows in that direction. thanks!

Man... kinda sux... no one can help at all?

First, this belongs in Q & A, hence no answer , second, it should be pretty easy, nandroid, switch out rild, and rils, make correct edits to build prop, and a kernel for ns4g and you should be good to go.

Are there any guides out there that perhaps detail this process a little bit, I would like to start porting some ns roms over to ns4g. I followed the steps provided by the previous post, and got most everything booting for the new miui rom with ICS however the wifi still doesn't work and it will not allow me to flash a different kernel as afterwards it refuses to boot. Any guidance would be greatly appreciated. Thanks

[Q] SebastianFM or faux123 or Bricked or Stock Kernel, which one is better?

Hi, i'm newbie on this forum, i have already done all stuffs like S-OFF and upgrading the software... I saw that the ARHD is the best rom, so i want to install it. There is SebastianFM, faux123, bricked (which i read on the forum that is great) and the stock one, but i don't know why choose one instead of the other.. I mean, are there real differences between them? Can someone explain me them? The problem is that everyone says that's what they have is better than the other, but better for what? Also, there are writed a lot of technical details that i don't understand...
I hope u got what i mean, thanks in advance for the answers..

I think that SebastianFM is closer to stock so it's a bit more stable,faux123 is a bit performance oriented so the battery may not last as much as in other kernels and bricked lets you customize lots of options so you can make a good balance between performance and battery life,at least from my experience but from what i've been reading here it depends a lot on the person,some might have issues with a particular kernel while others find it perfect,so the best thing to do is try all of them and see which one doesn't cause any problems and is the most stable for you,and be careful to wipe cache+dalvik before flashing them.

This belongs in Q&A not general, for future reference. I have reported this to the MODS, so they can move it.

if you're planning to flash jellybean then you need the boostrap from this post http://forum.xda-developers.com/showthread.php?p=19355021 , with that installed, go to dev section of the forum and d/l a custom rom and flash following steps in the op , remember always to make a backup of your current rom
sent from the gray stuff inside my skull

There are only two roms based on JB. And both have a guide to install.

Any links for some good n stable roms are appriciated.. Kindly help

So, you're not "lazy", just apprehensive. There's nothing wrong with that. However, what we do here on xda isn't to spend time explaining all the pros vs/ cons to all ROMs available, nor is it anyone's assertion as to what the "best" ROM may be -as this is all very subjective to the individual. There's a hefty ROM list of threads in the development section, so it's your responsibility to read over each one (that may strike you as interesting) and make your own assessment to which you may choose.
Also, each ROM thread by our dev team has explicitly detailed installation instructions, so there should be no reason as to why you would run into trouble -so long as you read, re-read, and fully understand what you're getting yourself into.
Also, there's a handy little help thread that I started for any and all questions, problems, etc. So, if you happen to run into anything, feel free to post there. Myself and a few others maintain that thread, so you should expect an answer without the need of posting a new thread each time you have a problem.

[Q] 2 roms questions

Hi, sorry if this thread is short, but i have two question blowing my mind.
1: Why don't whe have a 4.0.4 Cyanogenmod Rom?
2: And can we have a stock 4.1.2 rom? I mean, with motoblur, not cyanogenmod or that kinda variants
I know that motorola isn't collaborating with its upgrades. But, there is any chance?

First of all the boot loader is locked that means no custom kernel that means no proper CM builds, still there is an unofficial CM ROM in the development section take a look at it. And don't forget the funda "search before you post"..

You don't get me at all. I know that there's 3 roms of 4.1.2 CM.
And this was my comment about that, but no ones answers me:
I know that is hard, and i really really really apreciate the work that they're doing.
But, we have 3 roms of cyanogenmod, and the 3 roms have the same bugs.
I repeat. I know, they can't spend the whole free-time that you have working in the creation of the rom. But, why don't you team up and make a unique functional rom.
Or, am i missing something, and for the moment we can't have a functional rom because of motorola or whatever?
I repeat again, sorry if i'm bothering someone, but i ask this from my ignorance.

Then learn how to build your own freaking ROM, and why even start a NEW thread with this junk, it all fits in the CM Q&A thread.
These types of threads are not cool to your dev team. We all work very hard to bring the stuff that we do, to you guys, for free.
If you do not like the bugs in the CM based roms that we have then do not use them and stick to stock and stop basically complaining about it, or do some reading and learn about the process and see why we have these issues, we have all posted about it so many times now it is not even funny.
I saw your post before and chose to ignore it, but now that you have posted a new thread like this, I just had to reply.
--EDIT--
And to answer the questions you put in the first post here:
1) because the source for CM10 with 4.0.4 is not out anymore
2) because motorola will not release a 4.1 or 4.2 stock ROM and kernel, so we can not port that, even our 4.1 and 4.2 CM based roms are still really 4.0.4 because we still have the 4.0.4 version of the kernel underneath.
Again all this has been spelled out too many times now and some reading and searching could have gotten your answers.

I already said this, but, i do not want you to get mad.
If you can't response a single question without freaking out, then, don't answer.
I just gave an opinion, like i said, from my ignorance.

I am not mad BTW, I am just tired of people not doing their own research. You are more than welcome to do some reading on compiling Cyanogenmod, so that you understand what we are up against. Also try searching for compiling cyanogenmod on locked bootloaders.
We (all the A2 devs), have answered these same questions so many times now, it is not even funny. It seems that as of late people have gotten more and more lazy in here, and we just keep hashing the same crap over and over again.
You say it is from your own ignorance, but you do not have to be ignorant, just use the search function or do some reading on your own and find what you need. And I do not want to hear excuses or complaints about the search function, I use it all the time, all you have to do is play with the wording until you find what you want. Also note other devs did not answer your original query either, for probably the same reason, not to put words in their mouth's either.

Also I hate to tell you but most of your devs do "team up" and we work together on our IRC chat room to do dev work, but again reading around the forms would have also told you that as well, as we talk about it quite often.

I think only PA is 4.1.2 so far.. the others are 4.1.1, I think
And Jim's right, I also saw your post in the PA thread and started to reply, but discarded it because I felt I was sounding too mean.. let me try again:
I can say from my personal experience and (relatively low) skill level - it's a mess trying to get all the pieces in place to compile a working ROM from source code for our phone - specifically, the vendor and device files..
I know at least a few A2 devs are working to straighten things out for Edison directly - and a few others working on other Motos with similar hardware and locked bootloaders, which benefits us all.
It's probably safe to say that our phone is in the early stages of true ROM development (as opposed to derivative pseudo-roms and ports) - there is still a lot of work to be done to get something truly stable.
Again, please be patient, or learn and contribute... don't stir the pot.
