[Q] How to Port a ROM?

I was wondering if someone could give me a few basic tips on porting a rom. There arent very many roms for our phones but i would like to port a few that i like. (specifically from international GSII) Ill take any help, thanks

If you are looking to flash a rom, there are some detailed instructions in the Dev forum. In particular the thread for the Starburst rom. The first post has all the downloads you will need and there are some more detailed instructions on one of the posts from October 10th or 11th. Your device will of course need to be rooted in order for this to work.

Porting from international version is going to be really difficult due to the different radio's in it, and you would never get WiMax to work if you tried, even if you got it to boot up
my reccomendation would be to try grabbing a rom you like from another CDMA/WiMax Samsung device and try it, except the only one would be the Epic 4G, and the slideout keyboard orientation might ruin some stuff when porting....... so at this point, unfortunately, i dont think porting a rom is in anyones future for a little while at least til we get an AOSP kernel
cheers!

Port paranoidkang droid to tmobile

I am wondering how the policy works with porting an at&t ROM to T-Mobile as I am currently running this ROM which is a combo of AOpk and Pa but its by far the smoothest rom I have flashed and much more options than PA plus the video volume is loud as hell so since I am new to the xda community I want to know what are the rules of porting this bad a$$ ROM so that all T-Mobile users can use this as a dd do I need permission from thebz1 or I could just post it for you guys I have it all ready but don't want to anything against the policy please fill me in guys
BTW the link to the ROM is below

What did the original dev say? That is probably the most important thing.

is it not flashable to our phone? I've used some at&t roms on my t999 with no issues that weren't already expected. (WiFi calling and other T-Mobile things)

thebz1 was working on tmo Pa THREAD a couple month ago until he decided that he would only take care of at&t only that is why OG came in and started getting PA again but after flashing PA and PK i could tell you that PK is much more stable than PA, its much much smoother, the video volume is really loud, you ger rom control and paranoid android settings together in one so much more customization. i guess since it is an open source i feel that i should port it over , i was respectful by asking him so he doesn't own PK anyhow im going to be working on this over the weekend

Obviously both of you haven't tried the AT&T ROM on a T999 because it won't even flash in recovery, much less boot up. I know this because I've tried it in multiple stages of development. He was asking about porting another persons work, and XDA's policy. Yes, most AT&T ROMS work on t-mo too (as long as it doesn't contain AT&T modem), but lets not be redundant & state what most people in this forum already know. Thanks for the port bro. It's running like butter!

I'm sorry, maybe I've missed something...If I have, forgive me,
But, the original Dev did not give you permission to port his work over. Have you considered that he may have a reason for it? Perhaps he plans to support multiple devices with it, like many other devs do with their Roms.
That is just a guess, but if something like that were the case, depending on how popular the dev is, and how P.O.'d he gets, you could be making a lot of enemies on here....
Something like this, if you want it that bad, go ahead and port it. But do it for yourself, do not release it.
If you were planning on releasing it regardless of his answer, then you should never have asked.
Sorry man, just trying to help.....

one more just in case...

There is no way I could build on my PC it would take a week just to finish, by then we would be on CM 11, but yes this is a port of the n7100 CM10 nightly from today, the connection issues are because there is no modem I am sure, or at least not one that I can find, and I can't make it stick, and the sound is because it is set up for the n7100, that should be an easy fix that I will work on tonight.

Thinking about this, I'm not sure it will ever get cell network. Because there needs to be a compiled kernel with the Qualcomm modem enabled. And since this is the 7100 it doesn't have lte. So even with the correct ril files, it won't work.
We need an aosp kernel with Qualcomm modem support.
If someone wanted to look at the quicnyatt defconfig on cyanogenmod's site, you might get inside for the defconfig needed for the smdk4412
Also
Can I ask that we keep this thread to development purposes.
Please do not post OMG THIS IS AWESOME. That does nothing for helping.
If you have a development finding or fix, post it up. Otherwise please do not post.

Are the kernel modules similar for the Quincy as it has the Qualcomm S3 SOC and we have the Exynos? Would it not work to compile a kernel with the open source files from Sammy?

The quincy has the old snapdragon 1.5, it does not have the new msm8960 as the S3's do. Also its not about modules. I've downloaded source and its pretty horrible, as most Samsung crap is.
Compiling a kernel would work from sources, it just has to support aosp, since CM uses its own ramdisk too.

I am all for pure AOSP I just don't know how to do much. I am happy to help test but that is about the extent of capabilities right now. I love my stylus but don't need all the stylus "shortcuts". I ran AOSP on my note one and the stylus worked great even did good for the harder you pressed on the stylus the darker it would write. The only thing I lost were all the button and shortcuts integrated with touchwiz. I used papyrus as my snote/smemo replacement and actually prefer it over the Samsung crap that lost my memos every time I flashed anything.

All I want is AOSP, maybe a little Paranoid Android. S-Pen lost it's novelty for me after a couple of hours. I also must have misread the kernel post. NEAK only has a Sammy kernel
Sent from my SAMSUNG-SGH-I317 using xda app

Yeah, I'll chime-in, too. Only thing I'm missing on this phone is AOSP ROM's. TouchWiz is TouchJiz. Specific features or not, AOSP is where it's at, and I would seriously consider returning this device if AOSP development was to do anything on the lines of cease. Frankly, it's killing me that there hasn't been more AOSP dev'ing up to this point. Devs are all we end-users have, and believe me, if I had any talent in that realm, I'd be offering my limbs towards development. Only thing, is I'm merely a user. I will test anything I'm able to, though! My precious phablet is my personal lab rat! Hehe...

There is no firmware in /system/etc. The only firmware is vendor/firmware.
And isn't ro.telephony back from gingerbread? Or is than an aosp thing? Its not in stock Samsung firmware.
Also even with those correct, we still don't have a kernel with Qualcomm modem support. So until we get that. Its dead in the water.
Your better off trying the 7100 rom on the 317. Since we already have a supported kernel.
Also remember DEVELOPMENT ONLY. Ask yourself. Will this aid in the development of this rom before posting!

Quincyatt won't be useful. There's a HUGE difference between a complete integrated Qualcomm SoC such as found in the quincyatt and d2 family, and a Qualcomm modem hung off of the Exynos4.
So far, no one has yet to figure out the proper defconfig for this. Although probably you could get it by looking at the Perseus N7105 defconfig.
Looks like CONFIG_QC_MODEM might do the trick?

I care! 1000%! I've never used that crappy pen. AOSP is the only thing I care about.

I am also all for aosp just let me know how to help. What we've tried already is replacing the entire vendor and csc and build.prop from i317 and dropping into a n71xx ROM and flashing. In addition have tried a large number of random RIL associated files from i317 into n71xx ROM and still no dice with the modem. Have made sure that no modem or kernel are being flashed while doing this. Logcat -b radio still spits out RIL related crap. I don't know enough about kernels to mess with defconfig unfortunately but I'm willing to help however I can. Fwiw replacing vendor/CSC/build.prop was enough to get a sprint note 2 ROM to work on T-Mobile thanks to someone who did that already.
My time is limited but let me know if some of you guys want to chat about this together on irc or something. I'm on freenode a few days a week after 9pm EST.
Edit: I should clarify all the things above that we tested (lpsi2000 and I) were TW based ROMs but getting the modem to fire up in whichever sense when porting things from n71xx I would guess should apply.
Thanks Entropy for pointing out that. I have to add kernel to my long list of things to learn more about in detail.

Above is the link to the 7100 ROM it looks amazing.... What does it take to make this flash-able onto our T Mobile devices... If it doesn't include a radio couldn't we just flash it? I am too scared to flash and try...its less scary to post a new thread ask you to try...haha. If a devo could shed some light or a brave soul could "test" it that would be great.

You can flash it. If you want to lose your radio. Unfortunately even if the 7100 rom does not include radio we have significant differences in our hardware that causes the radio not to work. Most likely something in the ril or kernel I believe (I could be wrong about the reasons). We dont have an AOSP kernel for the 7105 or tmo version.

Thank you sir... man, I really want that ROM. Was using XquiziT's ROM but the was having a couple problems with it and now the future for it looks bleak. (What I liked so much was the AOSP parts added in) Going to give Saurom a go now I guess.

I am TRUSTING you!!! Don't let me down.... LOL (Ref: "..but we will catch up..")

we need some devs solely working on what needs to be done for porting from one device to another. the fact that the ROM even functions on our device without modification should be a decent indicator of how close we are.
look in the US SGS3 section, 4 variants all with small differences and porting roms between those 4 is a piece of cake.
if someone could make a stand alone CWM.zip that we flash after a N7100 ROM that gave us back the radio it would be perfect. then we could just run any N7100 rom we wanted, no porting needed.

well as much as i love the note 2 if we don't get any aosp love soon ill probably swap devices with my wife. at least her sg3 has cm10/aokp. again not complaining, i just hope development picks up. i was thinking about getting a nexus 4 to tide me over but i hate lg. if anything i still hope the note 2 see's android 4.2.

I am curious. I have had CM/AOKP for years with my other phones. With this one seems a lot of the features I really love are here. What do you feel is missing from TW that AOKP/CM gives you. I am not a fan of TW colors but overall it is good (and I xan theme colors away). Only thing I really miss from AOKP is the wigets popup from nav bar.

Aosp is lighter and for me runs better.

Personally I really look forward to having a ROM with mass storage support. Since Google removed it from Android, I am no longer able to connect my phone to Linux for easy transfer of files and have to use all kinds of alternatives.
Not sure it can't be done on a TW based ROM, but CM/AOKP ROMs seem to more commonly introduce it like the one mentioned in this thread.

I second the motion for USB mass storage functions. Maybe wi-fi direct or other technology will supersede it, but it would be nice to have the capabilities meantime.

This I can understand I really wish google made ums/mass storage an option. I understand why they went with ums but options are always nice.
Reasons why I think they went UMS
1) ability to keep sdcard mounted while connected to computer
2) ability to mount /sdcard on /data/media making the internal sdcard the same as the internal data memory
3) most people people use windows
4) the option to turn it on/off may confise some people.
The only one I disagree with is number 4. Stupidd people will find a way to be stupid no matter how much you coddle them.

if you know that it has nothing to do with this thread then why ask? And if your asking about a touchwiz 4.4 no one knows samsung usually takes forever to do this. For example they just started rolling out 4.3 for the note 2 so my guess would be about a year lol. And as for a AOSP KitKat...yet again no one knows btw never ask for ETA's

I downloaded this from Sammy a few weeks back, and I was struck by how little is there. Yes, the full kernel sources are there - though of course a lot of stuff is still hidden in binary firmware blobs (presumably the TIMA/KNOX interface falls in this category). What struck me though was how little *platform* stuff is there. Is anyone else surprised by this? I would've thought they built more of their work on open-source foundations, but maybe not.

Well you have to remember, 4.3 Samsung is 4.3 samsung. If you ever looked inside the apks, there is a ton of stuff not used. Reason that's so, it's more generic across devices.
The only real changes are drivers/libs. A lot of those get pulled from the device when building anyway.
As far as I've ever seen, an individual cannot build a lib. You cannot reverse engineer them. Nothing.
If the specific libs needed to make things work are not available, then they just won't work yet. It's that plain an simple. I've helped out a lot in source building threads.
I wish it was easier, but sadly it's not.

Well you have to remember, 4.3 Samsung is 4.3 samsung. If you ever looked inside the apks, there is a ton of stuff not used. Reason that's so, it's more generic across devices.

Yeah, I've done a lot of work administering standard linux machines and it's a completely different world. They may be using an open-source core OS, but it's clear that none of the vendors treat their development itself as a process that contributes to free software.
By libs, do you mean the kernel modules and/or binary firmware blobs that are needed to support different bits of hardware? Or actual system libraries? I guess in this case, both are frequently closed. I heard a couple months back that the Android lead engineer at Google actually stepped down over the issue of OEM-supplied firmware blobs - specifically how un-transparent the process is, and how it's hard to even get access to the binaries for distribution, let alone the source D:

I have 4.4.2 source. Github. Linux building environment. Now I'm making a stock ROM to upload to XDA. Anyone with time to explain how to do so. All info accepted (-_-).
