[Q] can someone teach me how to build a ROM

My friend owns an samsung galaxy tab 4 t-230 and would love to upgrade it into a more pure android. Since i kind of got into android ROMs and there are no AOSP or CM roms for the tab 4 t-230 this would be a great chance for me to build a AOSP or CM rom. I have ubuntu 14.10 and a decent enough pc with 16 gb of ram and an i7. If anyone could help me abit of how to build a AOSP or CM rom for the device i would be verry thankfull.
----------------------Edit-----------------------
I wanted to say thank to you guys! I did quite some progress by now. If you own a t230 / nu then feel free to check out my custom kernel

Relevant post - some starting info, and check out the CM wiki he links to. Also, and this is a very basic step, but if you've never done this before it can be informative: download a rom zip file (preferably but not necessarily a stock-based kitkat rom for this device) and open it up in either 7zip or WinRar, check out the layout and structure, and familiarize yourself with the updater-script. (Actually you can do that with a firmware tar file too). Sorry I can't give you any more useful info, not a dev, definitely not a rom designer, just a guy who knows a fair amount of android stuff.
Also don't let the tone of that post discourage you; the poster was answering a guy who was basically asking about the feasibility of building a brand new rom for the sole purpose of being able to use one particular proprietary Samsung app. Yes it is difficult, but still doable, and you say you're motivated...

Yes i did forgot to say that any links for learning are appriciated

Well.. I would ask moonbutt74 for more info regarding commands and such, probably more info than I can give but.. keep in mind your going to have to download about 20+GB of source code and all that. Also a bunch more knowledge of more things I don't remember. But it is alot
-DUHA

Well I decided to revisit this thread. Never thought I would come so far. I really want to say thanks to all of you who supported me and still support me. Everyone has a beginning and here was mine. Now I am actually there where I really wanted to be. Releasing a custom kernel and finally work on a custom ROM! Thank you XDA!

I'm amazed on how much people learn and achieve as well as myself. I've seen people who were total newbies then later built custom recoveries, CM12, Mods, Roms etc. Anyway good luck on working your rom!

Also I thank you my life for introducing me to moonbutt74. He learned me everything from how to work with custom kernels to Roms. Sadly he decided to stop developing a few Werks ago but he's doing it for his own good. I still will mention @moonbutt74 on my future projects because he really is the one who changed me from confused to knowing what is actually going on. So thanks allot !

AICP Rom Coming Soon

Hi, guys.
I found a video on youtube and a guide on xda on how to port roms from one device to another. Since the opo and opx almost have the same specs, I'm thinking on porting AICP rom to opx.
What do you guys think?
Im far from being a developer, but I want to learn, and I think this can be a good beginning.
Any suggestions or comments are welcome.
Edit: I'm not going to port AICP rom to OPX anymore, instead, I'm building from source.
Hopefully, we're going to have an aicp rom soon.

I think that will require more skills since it will be more difficult. :| But maybe with help from people that know I can make it.

I would love aicp on this phone, let me know if you get it going! Shout up Davor Bertovic on Google+, he's a developer on the AICP project, he might be able to point you in the right direction

The thing with this roms is that there is no based rom of these in OPX yet, and to port (as far as I've read) you need a port rom (rom in OPO) and a base rom (rom in OPX).
For example: I chosed AICP 5.1.1 because is based in CM, and we (OPX) have a 5.1.1 CM rom, so they're very similar. There might be a Color OS rom on OPO but we don't have a similar rom on OPX, and to port them will require some real development skills which I don't have. ;D

AOSP marshmallow would be awesome...I don't manage to build it cuz of a weird bug but maybe you can !

I may be wrong, but it looks like both of CM13 developers are really don't like ZE550KL/500KL/500KG users for some reason. If this is impossible to release it for us, then tell at least why?

Plss release the cm13 for ze550kl soon plsss . I wilk give cash credits for the developer

I wish people would understand that these developers don't just magically have all the Asus phone models. They are all different inside, from CPU to GPU or screen size and partitions. They tend to buy a single model of their choosing for their own private use and then when they see no custom ROMs for their phone they decide to do it themselves. They are not working for Asus. They are every day people like you and me who are nice enough to release what they can for this community. If you wish to see CM or whatever custom ROM on your device you will either have to learn how to port it yourself or buy that specific model phone for someone who is willing to do it for you. Begging them to "make it soon" or "release now" makes you seem ungrateful and childish.
A big thanks to the people who work hard on these ROMs and release them for us to use.

-snip-

I appreciate all of done work by developers and very apologize for being ungrateful. I really understand that if we didn't get CM, we probably never would have it. Once I got answers, I have no more question and I hope for small chance to get it for our devices.
If I could help to them with testing for example, I would like to help, I have ZE550KL. But I have no skills in ROM stuff.

[23/09/2017][K420DS/N][Android OREO] Android OREO Booted!

Hey guys!
NEWS 1: Guys, with help of another developer we are working on the device tree. The builds currently are booting up and there are bugs to be fixed. We have currently released LineageOS 15.0 first test build only to the insiders (.i.e. testers of K10 - K420DS/N).
NEWS 2: We will also be working on K10 MS428. We will be compiling LOS 14.1 for the phone.

+ I have a k430dsy device.

I'm working on the k428/ms428 variants and pvineeth97 is working on the 420 variants. Others may come down the road.
I'm building the device tree now based on a few unofficial builds for devices with the msm8909 SoC, so with some luck it may not take too much work to get it going for us. All depends on how much time I can dedicate to it.

Right on! Good job and good luck!

Once I'm done, and have it compiled and bootable, I'll need a couple beta testers to help me iron out kinks before releasing publicly (unless of course it just works flawlessly ). This is only open to k428/ms428 owners who can competently recover from brick on their own, and are willing to produce adequate logcats regarding any issues. Hoping to have a bootable rom in the coming weeks, we'll go from there. Keep in mind bootable may mean far from stable. Many things may be broken at first. If you're not willing to dedicate the time and work to help me fix such issues (ie, camera not working, audio not working, data not working, everything not working), please don't volunteer. If you aren't competent with adb, don't know how to produce a logcat, and don't know what to do with a bricked device, please don't volunteer. I won't have the time nor patience to walk anyone through fixing their device, and work on the port. If you feel competent, you can message me with your interest.

If there are any custom Oreo ROMs for our T-810, they are a very well kept secret.

the lead developer @T_I had some life stuff come up, and hasn't had a chance to look at bringing up the 810 to Oreo yet. Wish I knew enough to figure out how to help out with it.

Indeed, I'm battling with a concussion, very limiting my screen time. Also, to be honest, @RaymanFX is the lead developer for the 2015 Tab S2 models, I just managed to adapt his code for the T810 (not to difficult) and the T710/5 (bigger challenge, still needs a lot of work).
My prio at this point is to get the T710/5 functioning before putting time in, unless RaymanFX wants to start work on Oreo for the T815, then I can test the other devices. (alas, no real work for a while, just barely managing to get 4h of work in a day)

hi, not to open a new thread:
but official there is also Nougat 7.1 for the S2 2015 version.
Can i flash this and root it per superSu?
Is there any custom kernal avialble?
or better an "original" Rom just moded?
thanks for answers in advance
adddy2

The answer is quite easy.
CustomROMs would be easier to create if there'd be an official Oreo ROM from Samsung. The SM-T810 is still on Nougat (I got a "new" update a couple of days ago, which only "updated" the security patch level...).
Since Samsung released the S3 Tablet, there won't be any effort spend into developing an official Oreo Rom in this "older" Tablet, imo. The SM-T810 has an Exynos 5433 CPU (and not a Qualcomm), which means we're facing closed-source and therefore smooth and fully working CustomROMs won't be very likely.

The question is: Why do you want a custom ROM at all?
The stock Nougat ROM can be debloated (e. g. via Neked Maker), rooted, Xposed can be installed.
All is working fine, and you can customize it very much.
What feature are you looking for in a custom ROM which isn't possible with stock ROM??

There's no stock Oreo rom. For me, it's not that I want a custom rom, it's more that I want an Oreo rom.

Actually possessor of a T715 Tab S2. I saw someone managed to build an Oreo rom for T710, if the rom will come also for the sim variant it will be really great! We have to forget about samsung spending time for "old" devices....Instead thanks all the developers teying to get the best out of this tab and updating it.
P.s give me a working fingerprint and i'll give you mi life lol
