flashing i9100 roms to t989

i know its been asked but i'm starting the discussion. there has to be an easy way to flash all these great i9100 roms on to our tmobile t989. i would think its mostly a kernal difference and some hardware buttons. i say this because i love hyperdroid roms (mostly wanted s2 for use of his rom) .with the hd2 all builds worked on all phones (europe,asia,usa,etc) no matter the model number.
i am starting the discussion and will help to develop with my time and limited knowledge (i need people who know more about building these roms) a simple zip file to be flashed through cwm. most builds use a base version, then have roms and etc over the top of them. so there must be a way to find a base version you like for any i9100, flash over cwm, then flash a "kernal" of sorts that "adds in or takes out" what is needed for android to run on our t989.
any thoughts? anyone want to discuss this? i have the time (as much as possible, my gf keeps saying "why dont you just make your own and quit bit$%ing").
also i saw a kitchen for building roms for s2 but not sure if its t989 compatible.
lets get to work, our phone is new but the i9100 is already cooking along, we can piggy back and make our phones just as awesome!

Reading from the tittle of the thread, please dont do it! Just fall back..

So I understand you're not going to try to flash it but you're wrong about the major hurdle: Its the different processor. Since we have different hardware we're not talking about a slightly different radio, we're talking about two completely different devices branded as the same thing.

i realize its hardware, but isn't that all controlled by the kernal? it holds the drivers. it would be like "porting" take a rom everyone loves, make the hardware drivers work, then flash. like i said i'm limited knowledge but i want to start work on this. its a hardware thing i understand. but there must be something we can do to ease the process.

To sum up what Kevin said : It's like flashing a sensation rom on our sgs2...(Right?)

but sense has been ported to other non htc devices. my point is it can be done. we should talk about it and get a discussion going. i'd be more then happy to help "port" other roms that are out for s2 varients

Porting sense to non-HTC phones requires massive amounts of work and open source. Yes, it is possible but whether or not its feasible is a different option. You're right that the kernel is the main difference but even so its much more work than simply adjusting the kernel since there are soooooo many differences. Cashy put it well: you're porting a ROM from effectively a Samsung device to an HTC device. The only similarities are the screen and touchwiz. If you want to give it a go, I'd wait until we have a full ODIN tar to help you recover your phone because you're going to get a few bricks.

Well good luck to us all.
got my T989 few days ago, and I find it much better than the usual i9100 that everyone have on every aspect, except for the lack of support and android development. I regret I based my decision solely on technical spec rather than checking the verity of available firmware and development.
I live and use this phone in Israel, and that stock T-mobile rom I got with it is loaded with lots of irremovable T-mobile apps. Those are irrelevant for me. But the real issue is about the RTL support. I now have to read Hebrew text backwards (taht ekil hpargarap eloh a daer ot yrT) in some text fields. And it won't let me use the mobile hotspot by saying my sim card is not supported. I can't see why it connects to the internet (it does, checked my APN settings twice and it configured right) but won't let me use that hotspot.
Can't these changes in the level of GUI be implanted from other equivalent roms as source code? Does these minor changes take so much work? Before overclocking my phone to 1.89 Ghz I would rather get the basic functions done.
And I'm willing to donate, and to help in any way to promote this project.

I tried a similar thing with my LG optimus 2x (I have model p-999 which is really t-mobile's g2x) by accident. Even though the variations are named optimus 2x and the specs are almost identical, firmwares just aren't compatible with one another.
I flashed a optimus 2x firmware (p-990) to my p999 and I bricked my phone. At this point, even clockworkmod could not recover it. I had to manually partition a t-mobile g2x recovery file one by one on DOS mode to fix this. Finding this solution was like finding a needle in a haysack. I thought there was a good chance that I flushed $400 down the drain when this happened.
So, lol I dont recommend it knowing that gs2 is even a higher price to pay. Hope this helped.

it's something that I almost gave a try and then decided to check in here to see what people say about flashing these roms.. lol. Thanks guys

Lol I actually did try to flash cm for the i9100 on this phone, but thankfully it only gave me an error and didn't actually go through with the flash. (I had literally gotten the phone the day before too lmao)

It sounds like youve got porting perfectly understood. The devs havent been able to do it, you should explain how porting works to them.

The problem is not just the kernel. The software is most likely compiled specifically for the processor. If you were talking about linux . . . it would be easy because the source code is there and you can compile it for whatever processor you want, but it seems Samsung is a a company who believes in leeching off off open source and mixing their proprietary crap in it then keeping the sources closed and giving the open source community the finger. Just look at how they handled the vertical lines screen issue. Its all about money to Samsung.

Dude no need to be a punk, I seriously dislike people like you who make forums negative. He was asking a question and is trying to learn, which is more than some people do. Keep your negative comments to yourself. If you cant say anything nice don't say anything at all.

This thread was started in 2011, and hasn't been active in over 7 months. There is no need to bring it back from the dead to argue with someone.

Its not as impossible as it may seem(for the experienced dev) if u look in the dev section android88 has ported hellybean from the 9100. I'm learning & I've only gotten a bootloop at worse, haven't bricked yet lol.

It is possible with a port. The thing that brocks your phone in flashing an i9100 ROM is the kernel. If you switched the kernels, you'll just have a boot loop or no boot. Flashing another devices kernel is the killer.

Its just logic. If its that easy try it and youll learn the inside out of why. Put in a similar amount effort you are asking the dev to put in by learning something about the challenges you are asking the dev to overcome instead of assuming devs arent putting enough thought into it

[Q] Multi-window ported from Galaxy Note 2 to Galaxy S3

Okay, so we have all of course seen that Synergy ROM and GalaxyMod have gotten multi-window/multi-view (is there seriously an official name for it??) working on the Galaxy S3, and on 4.1.1 no less.
This is really bugging the crap out of me (and probably a few other frustrated people). See, I want to make my own ROM from stock with all the features I want, without having to even deal with ROMs like Synergy that just don't quite fit with what I want and what works.
So I shall ask the question many may be dying to answer themselves, and why not sit down and actually discuss it rather than say "oh go here and get 'x' rom lol".
How does one get the Galaxy Note 2's Multi-window feature working on a Galaxy S3 touchwiz (or perhaps even AOSP) ROM?
Simple as that.
We all know it is possible, since it has already been done. And even on a version beneath 4.1.2!
If anyone has any clue whatsoever, please contribute to the discussion. I hope that soon this can be useful to all who would like this feature.
If anyone has any arguments to me asking the question, I haven't ever found an answer, and I've searched almost anywhere I possibly could (even here). So please don't.
Thank you.

You have to code it into the rom your using. Which means ripping your rom apart down to the base code and redoing alot of the coding from scratch.
AOSP is not an option. If you dont know why then you might want to rethink doing it your self.
You will need to know Java and C++ to start with.

So basically what you're saying is that I should download the source code from Samsung and code it into the ROM? (can't think of any other way to get to the base code simply from my little ROM itself, so that's why I ask this) Never worked with actual source code yet, so I might need a few pointers. It has always seemed as though source codes for different sorts of software are handled differently. And that's true. The thing is, finding how to handle each person's/company's source, and I still have much to learn in that regard.
Call me a noob if you'd like, because I pretty much am. But even so I would like to learn. Just saying. (and before you say "oh, well then go look at the other parts of the forum if you're so helpless", I'm just throwing it out there)
Okay. I thought I saw multi-window on an AOSP ROM but I could be mistaken. Besides, I don't have to do it myself. I could probably team up with my friend who is a hardcore android phone modder like myself.
Yeah, I figured I'd need to know Java and C++ to legitimately code android itself. I'll probably be able to get it down completely one of these days. For now, I'm still learning it.

There is a mod on the sprint gs3 forums that has multiwindow. It's a flashable mod for sprint 4.1.2 rims only though. It's a lotmore work than just that though. Port Sprint ROM then add the mod. And more behind Tue scenes stuff.

You NEED to also know that the APKs themselves also need to be multi-view compatible. This means decompiling and re-compiling each APK for your device (with the change in coding).
I'm not sure if you'd need to change the build prop to match the Note2 as well, but I think your CSC can remain the same.

Thank you. I figured this might be moreso the case, as Team Synergy apparently made their ROM by using dsixda's android kitchen. Porting methods definitely must be learnt to get this kind of thing going.

So I'm assuming you mean we should use something like apktool. The question then is what parts of each code do we change/add to make it work. Alternatively, I have seen mods that make it so just about any app will work as well.
I'm supposing I should get the stock Note 2 ROM to obtain the build.prop? I dunno, I haven't done much with build.prop's.

You are better off learning to use Dsixda's Kitchen or wait on someone else to create a custom ROM for this.

Well...I actually already know how to use the Kitchen. It's really simple to use. You just need to know how to install individual mods after you do what needs to be done in the kitchen itself. The only thing I don't fully know is how to port. He doesn't give any pointers because he doesn't actually know how to port either.
And I really don't want to wait for someone else to make a ROM with it included. We already have two, and both are still pretty buggy. Synergy is notably slow (despite CPU tweaks) and there are quite a few apps that don't even work on it (for example, the regular e-mail app). I'm determined to figure out and know how top create my own ROM, but if I can't get the info I need to progress then it'll be pretty tough.
Like I said though. I'm determined to gain the knowledge to do what I want.

There are porting guides all over XDA and one in our very own development section. You could run a few things by the guy who made the CSROM BMB rom...and its not buggy as you said others are. It's has a Sprint base and works well with the multiview feature.

So if you want to create a Rom with multi Window you will need framework from gs3 4.1.1 4.1.2 and note 2 4.1.2. You do not need the source from Samsung necessarily as you can pull framework-res.apk with adb, but you need a thorough knowledge of java and c++. You don't normally start off doing major reconstructive editing to roms. If you have adk set up build an app first. There are tons of tutorials in xda and all over google. Then move on to theming and whatnot.
Remeber to hit Thanks if I've been helpful.

[Q] Why does Samsung S3 i747 ATT US have 4.1.1 ROM. ?

I have an i747 ATT US S3 which is showing it has 4.1.1 ROM.
Is that because I am rooted (but still stock ROM) and have missed OTA update(s)?

Nope. You haven't missed a thing, so far as AT&T.
They haven't released it, and nobody who's talking knows when we'll see it. (regardless of what you read anywhere).
There are a few ROMs out there, like Dandroid which are ported to AT&T S3s.

ROM Manager on my phone says "Your ROM is not set up to receive OTA updates..." Is that because it is rooted?
Also, can you list a few other ROMs for i747? It is really hard to hunt them down, that is, to find the ones that are compatible with YOUR phone.
I particularly would like to find one (or kernel) that has "sound improvement" module in it. I had supercurio's voodoo sound on my earlier S1, and the S3 sound for music is nowhere near that in quality.

Yes.
Look in AT&T Original Android development and AT&T Android development.
The headers tell all.

Although a harsh response he's correct. We don't really push favorites here. If you had looked for rom's you'd find them as they are in the development sections.

Question on rom choice

I'm new to s3 just came from s2, I have the t-999L model. Just looking for recommendation on rom, im not one who cares about newest version of android. I'm just looking for stability, battery life, and MHL ability. Any help would be appreciated. Thanks

We cannot recommend a specific ROM because a ROM that works for one person may not for another. Different people like different things in their ROMs. Also we don't want to take away from other developers who have worked very hard to develop their ROM. We can only suggest trying different ROMs until you find one that you like and stick with it.

All I can really tell you is almost of our TW roms are very good and very stable. (Likewise is good, but is a WiP)
Beyond this you'll have to just browse the dev sections as we cannot recommend one over another. (Xda policy).
Just find a rom you think you'd like and read the first page and at least the last 5-7 pages of its thread. This will give you an idea on what to expect for stability.
Good luck!

Hi everybody! My stepson just gave me his old T-999 SG3. I have his older HD2 which I have flashed with the NexusHD2 v4.5 on NativeSD. I've done more reading on XDA getting to know the SG3. I figured how what Knox is, how to root my SG3...y'all know the story. I don't mean to sound stupid but no ifs...ands...or buts, I need T-Mobile's Wi-Fi calling which I understand is not an APK but embedded in the T999s Touchwiz ROMs. I never really knew why there were "Android Original Development" and "Android Development" threads until now...one's stock, the other is not. It's impossible for me given I go to school full-time, work full-time as a substitute teacher and make the time to search every square inch of XDA for what I need to know though I have spent a lot of hours doing just that as I like to think I've made considerable progress getting to know the SG3. Until fairly recently I've been using the HTC Titan PI39100 and custom flashed and I recently sold them; sort of miss those devices today as I'm sitting on the Lumia 1525 to come down the pipe for T-Mobile. Meanwhile, this is really my first "jump in the pool" with Android on both my HD2 and SG3. What I need to know from y'all is what is the best and leanest (debloated) ROM(s) that give me this awesome Android experience so many of you are after and gives me that Wi-Fi calling which is a must? I have Skype if all else fails. But there is mention of having to flash a modem and while I don't mind flashing ROMs and other things which recovery has to do, I need to know if that is the same as the term "radio" when we were referring to the HD2, and what makes this "modem" different than the one I have in by device today which is baseband version T999UVUENC2 Kernel version 3.0.31-1962493 Build JSS15J.T999UVUENC2. I bought Titanium Backup Pro and have frozen a list of apps and other programs which so far have not disrupted my experience on the SG3 based on a couple of lists for the AT&T and T-Mobile variants. And before anybody takes a whack at answering all my questions, is there one "main" thread which can give me the "tour" of what is under the hood on this device and the terminology (lexicon) on its nuances as compared to the HD2? I want to give this Android experience a chance; thank you!

Hi everybody! My stepson just gave me his old T-999 SG3. I have his older HD2 which I have flashed with the NexusHD2 v4.5 on NativeSD. I've done more reading on XDA getting to know the SG3. I figured how what Knox is, how to root my SG3...y'all know the story. I don't mean to sound stupid but no ifs...ands...or buts, I need T-Mobile's Wi-Fi calling which I understand is not an APK but embedded in the T999s Touchwiz ROMs. I never really knew why there were "Android Original Development" and "Android Development" threads until now...one's stock, the other is not. It's impossible for me given I go to school full-time, work full-time as a substitute teacher and make the time to search every square inch of XDA for what I need to know though I have spent a lot of hours doing just that as I like to think I've made considerable progress getting to know the SG3. Until fairly recently I've been using the HTC Titan PI39100 and custom flashed and I recently sold them; sort of miss those devices today as I'm sitting on the Lumia 1525 to come down the pipe for T-Mobile. Meanwhile, this is really my first "jump in the pool" with Android on both my HD2 and SG3. What I need to know from y'all is what is the best and leanest (debloated) ROM(s) that give me this awesome Android experience so many of you are after and gives me that Wi-Fi calling which is a must? I have Skype if all else fails.

The only debloated stock ROM with working WiFi calling to my knowledge is Dandroid. I'm not recommending it over any other ROM, it just seems to fit the features you're looking for.

Modem/Radio/Baseband, all the same thing. You ate on the latest available build so you will need to stay on that NC2 modem regardless of what you flash.

Yup. They should all work just fine.

Did everyone jump ship?

Thete is hardly any development on this phone. My note 2 and 3 there were tons of roms. But it's dead here . Every one leave sprint? Not that i blame them sprint is pretty lame. ..

Nah, my guess would be that since we all know Lollipop 5.xx is coming, the developers are probably waiting. It's still a pretty new device too. Jmho...

Cm and asop romz are built almost daily n there getting more stable

Hybrid-X Stock ROM is probably the most stable and best rom out at the moment. He is also woking on a dark version of the Stock rom. Soo many options unlocked in this rom.
I use to use CM as it was basically "Rooting for Dummies" I am not cutting anyone down (I use to love CM) but you dont have to think with that rom you install and it does the rest it will even update the rom for you. You dont have to think when you have that rom, you are safe and should not have any problems which is why I loved it. However their roms were not stable and updating too often so I tried other builds and found Hybrid-X to be the best so far.
My guess is tho everyone else is waiting for Lolipop to arrive. But tx is still working hard on his ROM and is always improving it even when he says he is done for a while, all of a sudden there is an update or a new mod you can use. If you dont use his at least watch the build and see what is still going on with his rom.

Oh and Sprint may seem lame to you, but all carriers have their own pros and cons. For me I left verizon and came to sprint for the unlimited data and I pay a lot less monthly. Went from having to data-mine and count my megabites, to not having to worry, and I typically use 60-70 gigs a month on just my phone I get my money's worth.

Maybe we should all jump ship to Verizon or AT&T. Oh wait, there is no development on either because you can't even root their Note 4's...

I was also curious about this, I'm not too familiar with the whole developer side of android, so I'm learning!
When the official lollipop version is released for the Note 4, will we see more ROMs being developed?, and higher quality? Or should I expect things to stay about the same?
I've really really enjoyed several ROMs I've tested, I'm just curious what to expect once the official Lollipop TW is released.

Good things come to those who wait

Someone on the Hybrid page said they went back to stock and are currently downloading Lollipop. Posted screen shots too, won't be that much longer if this is actually the case. I would assume there will be a lot more action soon, or else the roms that are being made will be the best and there will be no need for a ton of different ones.

This was exactly the reason for the hault in production in KK roms. At least it was for me. No point wasting time on a soon-to-be out of date build. And to sum up the OP's initial post... for anyone who is not happy with the lack of roms for your phone, then there are options for you. You can learn to build your own roms and you can also donate to developers to support and encourage then to continue buildg roms for free. The only reason i started building roms for the Note 4 was because there was really not many if any devs building roms for us sprint users. I made the choice to get off my @$$ and do something about it instead of crying and making posts about it. FYI to anyone not aware... building roms takes a LOT of work and a lot of time. Take that for what it's worth. I would love to sit on my @$$ and wait for awesome roms to come out and not have to build them myself!!! That's the sweet life!!! to those of you who have shown your support and respect to the few devs here in the Sprint note 4 forums, we ALL Thank You!!!
