AOSP ROM development, where to start? - Android Q&A, Help & Troubleshooting

I am attempting to build an AOSP ROM for S8 and I'm not sure what is required nor where to acquire said requirements
So far I am assuming that the Proprietary binary/blobs are kept in /system/vendor, but I'm not sure about where to acquire the device tree for S8
If I need anything else to compile AOSP for S8 please let me know what I need and where/how I can find it
Also PLEASE let me know how I can do this safely so that this won't hard brick or damage my hardware
Note: I DO NOT care about compatibility at this stage, such as camera not working, finger print reader broken, and so on, as long as the os itself works, after I confirm the os can work successfully I will attempt to fix the incompatibilities

You could look at the lineage os thread

i would prefer if it is not based on an existing custom rom to avoid copyright/ownership issues, eg forking a custom rom and claiming it as my own is basically copyright, unless i am explicitly allowed by the developer of specified ROM

Yea that's what I asked couple of posts ago but the devs keep it secret and ignored my request .. Never saw that ppl keep device trees secret but here ..

Before to start flashing
This is an UNOFFICIAL version of CM12.1, so this means that have bugs that i hope to fix soon. So use it carefully at your own risk. The most important thing to say, after flash this ROM,is ....

*
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.

Thanks for the rom, but where is the download? All I see is the download page for TWRP
Still uploading. I will advice you when finishs. Anyway its a testing ROM...not for daily use.
Does this has any problem with battery draining more than the stock rom? because this problem existed in my old ? z1 and i can't find anything related to the camera, so am asking if is it working? and any chance of porting z4 camera framework so we can use superior auto in this rom? Thanks in advance
I think is a bit premature make these kind of discussions now. When i'll make this rome stable (now it's a test build, have some reboot problems probaby lrelated to thermanager config) we can face more problems. But don't worry, any problem/idea will be faced at right time.
Awesome! Thank for your work!
Thanks for excellent work! Hope some major bugs could be fixed asap [emoji481]

WiFi not working???About Sound too??
And This is Android M or Android LP???
CyanogenMod 12 is based on android 5.x so that means this rom is lollipop
I'm waiting for the upload because the rom boot loops for a thermanager problem. Anyway i have fixed also sensors. I'm not able at this moment to offer more infos because rom boot loops. When i fix the thermanager config and rom will be stable i could be more detailed. I'm sure that RIL and 3g connection works. Wifi powers on but not reveal available Wi-Fi but i think is a configuration problem too.
Let me work guys, we are so close
Great news. Thanks God for You.Good Luck and we will wait for results

If you can force enable adb and upload the rom I'm sure that we can send you logcats to find the problems. Also, could you upload the new TWRP that is mentioned in the OP?

Hi, under GPL v2 license you are required to link a copy of the kernel you used, otherwise, would be in violation of the license. Thank you.
I have taken a look at your source, would it be possible if u rebuild it with Sony's Unified Kernel? Thanks!

I'm not violating anything, i'm not reselling or forcing someone else. I don't understand all this pressure, you have all the informations you want now, you saw my sources. The kernel is the same published from sonyxperiadev. I have to fork it to my page to be in rule with GPLv2? I don't think, i think is useless.
If you want that i publish my sources (already unstable) on the first page, i don't see the problem, i will do it.
Also, i see this discussion only a waste of time that i subtract to my work.

It's the temp .config file generated when u build the kernel. I renamed it and used because differently from the asp defconfig is formatted well.

I see no problem here especially since Sony hasn't exactly released the kernel code. There is no reason to be so distrustful. Heck he hasn't even released the rom yet so what are you complaining about. Please don't take offense. He is just trying to further this community

Supports developers, do not lock their work
I don't understand this mentality of 'Let the dev work and do his thing' and saying that he should be given space to himself to work and build CM12 for The M4 Aqua. As it stands, you all don't know what Open Source Means. The M4 Aqua is in a state where much dev work is needed and all you guys do is hamper the speed at which developers can build ROMs for you. Without Kernel Source code and all LOCAL modifications uploaded, other devs can't jump in and help out to build for the M4 Aqua. I work mainly in the Xperia SP Forums and when the Xperia SP got released, it barely had any source code given by SONY but now we're at CM13. CM13!!!! From a 2012 device to 2015 we have gotten CM13 while YOUR M4 Aqua is stuck at even building CM12! All the Xperia SP had going for it is the AMAZING DEV support with SO MUCH OPEN SOURCE CODE that we all learnt to share. We keep the credits individual to commits and we all gave credits which were due in every rom we built.
If I can't build the ROM with what you say uses the original sony kernel source code, then this ROM is violating GPL code. I will be back soon to test the results and see if it does indeed build and churns out the exact bugs reported. If you are unable to handle even a small request that Boylush has said and say that you're already stressed out due to ONE MEASLY request then there seems to be something wrong.
Those of you who have absolutely no developer experience I would advise you to refrain from trying to defend your individual parties and let this be easily settled by simple building on my end.
I don't like these kinds of reasoning about me and about my work only because in two months other people aren't been able to boot nothing, also a recovery. This is the last time i will respond to you because this is a DEV topic, and here will be DEV things.

I repeat this thing again, all my sources are public. Just see the first page of this topic. And also, all sources are open on sonyxperiadev and are a intellectual property of Sony. All the LOCAL modifications are on my github page, in the commit area. Just click and see.

And i'm happy for the Sony XPERIA SP, this means people work together. In the case of Sony M4 Aqua i just saw topics that bumps out after i started to develop, also if only the recovery, for this device. No one sent me a message for say, "Tony let's work together".

I'm not stressed, i feel great thanks And again no one ROM violates the GPL license. Simply because there isn't yet on the site and will not be until will complete boot correctly. And about the request, i responded yet. I have to repeat that i used the same kernel published by sonyxperiadev site WITHOUT MODIFICATIONS ?

Probably in the ROMS world this sentence is true. But i'm a graduated ICT Engeneer and i worked in past in Android. Maybe i know a little bit of devel things, and i say "a little bit" because i know i can do it, and i not let you and others to offend me without know who i am.
CONCLUSION
Without me, the unexperienced, this device today has a working recovery and i hope for ALL THIS COMMUNITY a working CM12.1 . And i repeat again this thing: THE SOURCES ARE PUBLIC ON MY GITHUB AND ON THE SONYXPERIADEV GITHUB. I'm not blocking the work of anyone and i will be happy if someone else will make the rom work better and efficiently than mine. I will learn where i failed from the other devs commits, like i always did.
I hope is more clear my point of view now to avoid future noisy discussions.

AOSP base rom for Redmi Note 4(MT6797)

Hi
Please build or port an Aosp rom to our great devices.
If somebody agree with me, please strengthen in it.

If you already knew then why did you start a new thread?
Why do some people think that asking for a ROM will make it magically happen faster or something?

Do you use AOSP rom if that rom don't have fingerprint function (because RMN4 use FPC1035 with MTK TrustSonic enabled, it's so hard to port it unless Xiaomi release kernel source code) ?
Most people asking for porting rom from other devices but also demand porting rom have full functions working like original rom which impossible to make it happen...

Yep. As I said in the X20 kernel thread, it's only just the beginning because that's only generic X20 kernel source. ODM's *always* add their own hardware that is not covered by the original kernel source.
Typically, Camera and Sensor drivers were the most difficult to port (with blobs and reverse-engineering stock firmware). But TrustSonic sounds like it will be the biggest task.

WelI think it is just as good making normal roms. The in-call isue and other bugs are related across all N roms so that means that if it gets fixed on one then you'll have all the other roms fixed in a small matter of time and now you have 3 working Nougat roms instead of one non functioning rom

Not at all. At the moment you have a lot of not working ROM that are not going to work, because if you look at their github, you'll see that authors most likely lack knowledge needed to make them work. Building every ROM available using the same base is a waste of time (and distraction for users) if one can't even fix your issues in one of them. Plus moving to newer version of android without having the previous one fully working is a suicide run. Nougat has a lot of complex changes in it's sources and it doesn't even fully work on some officially supported devices, so don't expect a good ROM of Android 7.1.1 anytime soon and flooding forums with multiple ROMs having the same issues is not going to help it.

Well... You are right sir. In-call audio is really really important and I wish someone knew why it was happening..
I didn't mean in call audio. I meant this ROM doesn't even boot normally and they have no clue why, yet instead of trying to debug they release bunch of not working builds. Camera doesn't work and it will not work since you'd either have to use updated open source HAL or revert Nougat media changes and it won't be a surprise if I'll tell you they have no idea how to do it. The only real devs, who knew what they were doing left because their work was posted by someone else and now he's making blind commits in hope that things will magically fix themself. They won't. I might as well tell you that development on J5 is dead unless someone new with actual knowledge steps in. Don't expect any significant changes. We can't even take patches from any other msm8916 devices, because they have more advanced development and use a lot of open source projects instead of prebuilt libs like we do. Even camera in CM13 is not fully fixed because open source cam doesn't work for us and after debugging it for 3 weeks I've still didn't come up with reliable solution to make it work (only made some errors dissapear).

You're not totally sure.
Creating new roms is just to try to see if there are different results and not just to flood the forum with crap.
The name of the forum is XDA - DEVELOPERS, this means that it is of full use to developers, if the person does not know how to help, it just stays silent while someone else can do it. Your help in testing is much appreciated since we are trying to do something free for you, and still prefer to say things like that.
I thank you and respect your concept, but try to help instead.

The problem with incall and other stuff is already encountered by SoUnd001, but the big problem is that we're not hitting what it does so it's not booted, you're getting errors with incall and stuff because of the patch you're installing, not because of Rom or current kernel.
NOTICE:
I'm finishing a build for J500FN, we know it may not start properly, but I want to know the result for these users. I hope the sooner I have it all working.

Considering our device only has Marshmallow we can afford to deal with some bugs. If i read correctly RR 6.0.1 only has the radio bug so we have a working Marshmallow rom. The next logical step is to make Nougat and they do not have a kernel thats Nougat based so thats why they are running into problems and why we have to use patches. Im almost 100% sure that once we get official Nougat to our device, 99% of the bugs in these roms will disappear

FYI: ALL custom ROM are using the same hardware repo's maintained by CAF, CM(Lineage now) or AOSP. There won't be any different results. The most important repos are all the same. The fact that you don't know that and your friend's github sources show that there is nothing to be helped. You're just playing games with users pretending you could make things work. What for? In the end they will be the ones left with nothing but promises. People, who could actually do something left, because someone took their work and published it to take all the applause for it and now you're blindly trying changes hoping they would somehow fix things.

They built from the source already made by ganesh. Their own changes are blindly trying things that have no right to work in the first place. Builiding android from someone's ready sources is like walk in a park.

Certainly not for J5 2015, maybe 2016 but it could benefit us anyway since these devices are similiar.
I'm done, Moderator will probably soon come and delete my posts since all they care about is keeping forum clean. You may consider this device dead at the moment.

I understand from your post that Sound001 or EsromG5 did the hard work, but its not like that.
@Nick Verse and @ganesh varma were the ones who built cm12.1 and cm13 from source. They were also working on cm14 source while they were working on cm13.
So, please edit your post and dont mislead people.
Koloses said everything.
Since Nick and Ganesh left J5 development because their project which were working on was posted by someone else, the issues of Nougat CM/AOSP based roms wont be solved.

Trust in rom and kernel developers

Hi all! we as users try so many ROMs and kernels on our LAND. And we trust developers that they wouldn't spy on us via their ROMs or kernels. I want to ask all of you what if a developer of unofficial ROM decides to put malicious code and invade our privacy. Is there a way by which we could be sure that certain ROM is safe to use ? I am talking mostly about unofficial ROMs and kernels here on XDA. If you are a developer or knowledgeable do reply?
I'm not a developer but I'm trying to answer your question.
For safety reason: You already throw the safety away right after the bootloader is unlocked... Why do you even questioning about safety right now?
For the transparency of the source code, I choose the one that open for public. Most custom ROMs have source code which is open for public review... And maybe you already knew that MIUI doesn't has it, most of their source code were closed. Also, MIUI put advertising on system level while Custom ROM doesn't.

Nitrogen OS

i want to get started with customising my own android

hi peeps. thank u for stopping by
i want to get into android development and make personal touches and changes to my phone. i quite like oxygenOS so i would like to stick with this and modify that slowly. but i cant figure out how to begin specifically with oxygenos? it doesnt appear as if they release their source code anymore. could anyone please point me in the right direction? thank you

Hi,
First of all, OnePlus do release their source code. But if you want to modify your phone and keep OxygenOS, you don't look it the right place.
With root you can have a lot more possibilities for customization, so I'll advice you to check Magisk (a root manager/ customization tool with which you can install modules).
If you want to theme your device you can use Substratum, and install themes from the Play Store.
Search about them and give them a try if you want to

thank u for getting back to me! i took a look at their github page but it said they stopped releasing the source code because it can be found elsewhere, and i cant find where exactly that is. i dont want to modify the OS as is (root it and customise that way), i mean getting the source code, changing, removing and adding things and then flash my own custom flavour of oxygenOS onto my phone. i figure going with what comes with my phone is best when getting into android development so that there are as few compatibility issues as possible. would you be able to point me exactly how i might obtain the source code? it would be very cool my dude

Check under the Android section on that page. Which specific OnePlus device do you have? There are many of them. I can help you find it if I know your model.

i see where you mean. but it seems like they stopped doing these releases. on their latest release (11 months ago) they said; "based on conversations we had with our dev community and the fact that we have only made few changes on AOSP(Qualcomm BSP) device tree, we will not be releasing AOSP device trees for future devices, the community can get the baseline from our device and get the source code from Qualcomm."
"the community can get the baseline from our device and get the source code from Qualcomm." i have no idea where to get what they are talking about.
i have the oneplus 8 pro

They're probably referring to CAF sources for the Qualcomm bit. The baseline part is probably a reference to the script that's in the Android section. This is the closest thing to what you're after that I can find.

ah yes. my brain has clicked with the baseline part, i would plug my phone in and it would use adb to extract the "baseline"? i understand this process. is what i am asking for difficult? perhaps i am better off taking the kernal files for my phone and integrating it with stock android that i would build and practicing with that? i really appreciate your effort but this "android blobs" is apparantly for reference only, i have no idea what android blobs is. i went into this knowing oneplus isnt extremely AOSP friendly compared to Sony for example, but i am going to push on. do you have any advice? this doesnt appear to be a friendly introduction into existing OS modification by sticking with OxygenOS
