[GUIDE] AOSP Porting guide - T-Mobile Samsung Galaxy S II SGH-T989

Saw this on the front page of xda today. Mr.Highway from team inferno (mt4g) created a guide for porting aosp roms from one device to another.
He said his guide should work for almost any device. Figured id post this in our dev section. I am in no way affiliated with this guide or team inferno. All credit goes to Mr.Highway.

This is useful stuff to an extent, but without sources and drivers, it's near impossible to make an AOSP ROM like ICS as you'd figure. We don't have any of the distinguished code to make the ROM "compatible" with our device.

How about an HTC Sense port? Last i heard, HTC was to release the souce code for the Sense UI or something like that for DEVs.

What do you like about sense? If you just want the looks like the 3D interactions... There are launchers for that

A better question would be is a rom ever complete? There will always be bugs that are found that do need to be fixed just like Android in general it's never really "done" there are always updates to it that fix things.

Well you do realize that our phone is CDMA, Proprietary code is not available for some of the hardware which greatly increases the time it takes to develop our phones ports.
If you like the idea of a Complete CyanogenMod you should grab an international GSM phone preferably a stock AOSP device. You will have a "complete" rom alot faster than you ever will with a sprint device.
The OG epic only became officially supported not long ago.

There is no "official" GB rom from CM for this phone. Rootzwiki has an "unofficial" CM7.1/2 that's no longer supported however. We are getting "official" CM9 and the Alpha 1 is in the Dev section.

There are at least 3 or 4 Cyanogenmod attempts for our phone, isn't that a set team that always develops or can anyone attempt a Cyanogenmod? Don't understand how there can be multiple Cyanogenmod ROMs for our phone?

I think you mean to say there are multiple AOSP-based (original ICS w/o Touchwiz) ROMs for our phone.
Sbrissen and Darchstar are currently working on CM9 for our phone.
T.C.P. has released AOKP, Gummy, and Codename Android for our phone.

Anyone is free to take the CM code and build their own ROM. That's the beauty of open source. All they ask is that such derivative builds are labeled as kangs or otherwise make note that they are using CM9's codebase.
Anyone can become a member of CM if they do good work such as committing bug fixes to the project and take a role in supporting CM on a particular device
Darchstar's build should be considered the "official" CM9 build for our phone. He's part of the CM team. However, until he or others are able to build a working kernel from source for the E4GT and not use Samsung's we won't have a truly CM9 build.

No rom is complete without official ice release.. they don't even have source for our phones yet for ics. Therefore it cannot be completed.. plus kudos to the person who said it will never be complete based off of bugs plus there are always ways to improve a rom regardless; of how "complete" it is.. would you want a dev to make a rom then never update it? They can't make it official until everything is working..

Nothing is ever finished in android
Notice the carriers always pushing fixes. ICS will probably be updated within a month after official drops.
Just the nature of the beast.
Sent from my SPH-D710 using xda premium
Android has become more and more complex to develop for (both in terms of skill and computing power), and the true developers (not including people who just modify existing roms) have become more spread out across devices.

Rom porting

If a Rom is built off aosp could it potentially be ported to any phone? I'm specifically talking about the firefly Rom for the Samsung captivate. It's all aosp and no touchwiz. I can provide a link if anyone would consider actually porting it.

Yup, that's it. I see now its actually a touchwiz based Rom.
I knew it was froyo, I just figured if it was portable, maybe a nice dev could add the theming to a newer base? Lol not sure that makes sense. I just know that I've flash atleast (the very least) 3 roms a month. Back when I had my captivate, I stuck to the firefly Rom for months. The look had color and style, but didn't dream "I'm 13" lol. Guess its really the theming I like.

But why 4.2 ? Do you really care about the source codes upgrades?
All the "cool" stuff you guys are mentioning can be EASILY modded into the Sense roms.
(as a general rule: anything which is available in an AOSP rom can be put in a Sense(or other OEM) rom, but not the other way around.)
If its just the number to show off, you can easily edit that with prop-editors.
The camera, sense app integration, sense widgets, all the really useful stuff will be gone.
ANYHOW, it can easily be ported once the source is released.

[Q] What can I do to (help) port Sense 4?

TBH this forum seems a bit lonely... and my EpicParts question was easily abandoned
Whatever, greetings and happy new year to every one out there!
Today I happen to dig out a Sense 4 ROM for our E4G which boots, doesn't reboot THAT often and is resized well (what, you want links? I think that's a private workspace and maybe I shouldn't tell). But what bugs me most is that SystemUI (statusbar) always FCs for no reason and I can't do anything with that.
So here I got a HTC Incredible S ("vivo", which is the port base for our Sense 2.1 ROM) with a fully-functional Sense 4.1 build. Everything's working and things are better sized for WVGA. And it's smooth. Considering it's a single core device, I think there is already no obstacle blocking the port (I know that Sense4All project paused because One X is a quad core device and gets all sorts of reboots. Correct me if I'm wrong).
Thus, I wanna ask, as a non-coding noob:
1) Is porting process the same as common tutorials (copying frameworks, libs, etc)?
2) If not, is this even possible (to have Sense 4.1 ported from vivo)?
3) If not, again, what can I do to improve my current build on hand (i.e. simply stopping the SystemUI FC and maybe adding more HWA)? I don't intend to use the ROM as a daily driver... Just a tool for showing off
So... Thanks again for reading the thread and hope you can offer some guidance
Sent from HTC Incredible S @ Sense 4.1
If there was a stable version of Sense 2.1 or 4.0, it would be my daily driver. I really hope this project isn't abandoned.

2.1 is already very usable apart from BT (nah I don't use that), but many devs have already left or are silent. Must be with their new toys. That's why I'm trying to help. If I had time in winter vacation I'll try a bit, but hope not too high
And so I need some guidance and answers... Please. Even one answer will do.

I do want to, but I'm not a code dev and know almost nothing except that "brute-force" porting method, and I don't know whether that will work.
I mean, here I got a fully working Sense 4 build on a SINGLE-CORE device, so is this a proof that porting to us is also possible?

But... I said
1) We HAD a now paused project that has ported Sense 4 and made it boot
2) I have a better Sense 4 base ROM (for our device, not HTC's) at hand with fewer random FCs
3) xboxfanj said that the port reboots because One X is quad core, and the ROM will keep searching for the extra cores. But IncS is single core and runs that beautifully (its port is based on One V and Desire X)
And that's why I'm seeking answers.

Part of the problem is that we couldn't port qualcomm roms which would be stable if they booted, but we never got it booting. Tegra is all intercoded into libs and looks for kernel files we don't have which causes it to reboot and be unstable.

To be honest, we never quite figured it out. We never got a proper logcat, since it only gave us unhelpful information, which means it doesn't even start to fully boot.

And this means all my expectes efforts should be in vain, huh?
But check this, I got a Sense 4 ROM from marcusant's site and it's a port from Desire Z, based on One V seemingly. So far apart from all the hardware issues (wifi, cam, sensor), only thing that prevented me from sticking to it is that SystemUI often FCs. And I think that is another base to start on, since IT'S QUALCOMM.

Is that so? There are two items in About Phone indicating phone model. One of them says "HTC One V", which I think is the port source, while the other says "HTC Desire Z", which is the device ported to I assume. I know that these can be modded, but why the hell does anyone take the trouble to mod it to Desire Z when we are Epic 4G? Thus I think it's a Qualcomm port.
Have you looked into it yet? Or maybe it's really your work and you know about it?

[discussion] aosp and cm

why dont u people try to build an AOSP rom instead ofa CM....coz probably cm is sumthing that is modifications made to AOSP....and even the touchwiz ui is modified AOSP so if we can have a AOSP build itll probably be easier for us to build these roms..
...if sum one is ready to help me learn about building roms from source ill sure try making CM's and AOKP and paranoid and what not
is better but its based on AOSP.....its like imagine AOSP as a stock rom and CM as a custom rom...wait why imagine..its actually like that....so the basic idea is to improve performance...where CM show up...but whats the base CM uses??...its AOSP....so if we have a perfect AOSP which is obv possible...coz Samsung wouldn't be able to build TouchWiz withouta base...for obv reasons...so why not try building an AOSP first and then continuing with CM
do u even know whatcha sayin?
tl;dr
Here's some math:
No sources = no base
No base = no sources
No sources = no cm
No cm = no aosp
So unless you try to find a way to make those proprietary sources available then I'd suggest doing some research.
Also even if you tried you'll fail, we have the best devs for sgy working hard for that goal and we're honestly not making good progress. Well except for percy and his cm9 and psycho's cm7 but still a long way from "stable as stock".
This post is in compliance with the national potato safety regulation.

My information might not be correct. A friend of mine told me this.
See cm is made by aftermarket developers keeping in mind that it can support lot of different phones.
On the other hand aosp was made for nexus phones so they don't give a damn that it works on other phones or not. They are just selfish lol.
So building pure aosp is tougher compared to cm. Cm has modifications on aosp to support different phones.

Naman...we haven't tried making AOSP yet so we cant just confirm this and it cant be that it was made for nexus only coz its an open source project so they must have probably kept in mind that many dev's will try to have it on different devices ..... the Gingerbread that our SGY uses is nothing but a custom rom of the aosp which we call as stock....
for obv reasons...samsung would not have made their own android os right...they have used google sources....the point is...the time dev's have spent on making CM if would have been focused on AOSP we might just have a build close enough to psycho's work!
and what ive learned or i might be wrong in this that psycho used aosp's sources for the fixes....Maybe wrong about this...i just read it somewhere here!.....and as our device has the largest community of awesome dev's why not we try the AOSP thing out??
we cant just conclude without trying...can we??......some months back people were like we wont have a CM....we have a working CM7 and CM9 which are working pretty fine except for the driver bugs....same way,we might just end up having an AOSP...
another hope to Young GT-S6310. need a great developers to make it true

Maybe you should see this. www.cyanogenmod.org/about
And also about android opensource project. Google gives aosp source to all manufacturers as part of aosp allience/programme which they further modify. And first phone running android was not nexus to say that they don't give damn about other devices. And the number of devices running CM is still very low.
Like I said, a friend told me about it.

Kernel? yeah there are huge number of kernels here but if you notice that most of em have same features See other phones like nexus 4. They have whats called "real" kernel development.
Pico which is 1k more expensive is 100 times better than this phone and you also know it. Why not buy that? I sold my Y for 3.5k and another 3k can buy you a arm7 phone. Which wont get outdated for another year atleast..
