Questions about Exynos and Android development - Galaxy Note 4 Q&A, Help & Troubleshooting

Hello dear, I have a galaxy note 4 which is an N910u (exynos). I know that CyanogenMod does not support this s**t. Also, I miss the old days with my CM 11 s3 LTE. Therefore, I want to contribute to the work in bringing CM into Exynos. However, I am NOT a well educated developer or even a developer. I googled many pieces of information, I found that there are just too much. I can hard to related them all into a single system. So I got some questions in starting my journey. I will be glad if you can help me. Thank you.
1. Apart form git, what should I learn in order to start my journey?
2. I am wondering if a person (LIke me, not even a developer) can look into Exynos Chipsets. Or should I leave this out?
3. I can't relate the role of Kernel, Baseband, Recovery, boatload and Rom in a phone. Even if I have googled what they are, I still haven't got the idea of them. Could someone please help me explain them in a simpler way?
I will keep this post updated.

Hello? Anybody here?

CM is available for the Note 4 Exynos: CLICK
It's still a WIP though.

[Q] Noob question about i9500 sources

Hi,
I know a fair bit about linux and programming and got an i9500 in India.
There seem to be a lot of (legitimate) hate among developers regarding the Exynos5 due to open sourcing problems by Samsung.
My main question is that there are various kernels such as Wanham and Perseus for the i9500, can't the ROMs be built from those.
Is there a noob friendly guide so that one can understand that. I searched, but didn't find anything. Will be great if someone can point me in the right direction. I am sure I am missing a lot of info and want to help in any way I can in making the i9500 ROM.
Thanks in advance guys. I had the CM10.1 on my i9300 before this phone and die everyday I have to use TW.

i would like to know the answer to this as well!

[Q] CM12 / AOSP Kernel DT2W n9005 / Note 3 HLTE

Hi.
Ok, so I know you guys at xda HATES threads like this, but please hear me out. At least I think I posted it in the right section
I have been searching for days (I promise, so either I'm slightly retarded, or there really is nothing to help me), both google and xda, about different ways to get DT2W on my n9005 Note 3. I'm running CM12 nightlies, and am very happy with it. But I need this, my Home button is broken, and the Power button is well on it's way to break too, and it's a hassle to push it anyways.
I've come up with two solutions:
1: An app called Knockr. It seems to work, somewhat, but after a while I found it to be REALLY buggy. So, uninstalled. Option 1 is no longer a viable solution.
2: Change to a kernel with DT2W support.
Now, I have never flashed a kernel before, but this is what I've figured out:
First, make a backup of boot.img
Done.
Secondly, find a kernel that supports your device AND rom. They are different for TW and AOSP. And different for each device (well, some support multiple devices).
Not found.
I simply CAN'T find a kernel for AOSP roms for the Note 3. I found ONE, it was called "LeanKernel", but it was very simplistic in the way that it was the bare raw of necessities, to prolong battery life and such, no extra features.
So here is my question, and just.. please don't ask me to search more and learn about kernels, I am sick of google right now, and my GF is harassing me about using WAY to much time on this problem.
Are there any other kernels for CM12, n9005? With support for Double Tap 2 Wake? I see there are some for TW based roms, so it should be possible for AOSP as well, right? Please pretty please?
Just a straight answer, or a link to some kernels? Just.. something..
I've tagged this thread as best as I could, and made the topic as informative and specific as I could, in hope that others like me, will easily find it when searching. So.. Yeah... Think about the children, the newbs and the wannabees.. Help us out. Post some good info if you got it
Thanks in advance.
BUMP
Damn I need to find an actual AOSP kernel too...I'm doing some searches but can't find anything...let me know if you find one plz!

[Q] OK... 'untouched' Note 3, want a Note 5 ROM... Now what?

There's so many different ROM's and Kernels and whatnot I'm lost.
I have an untouched 4.4.2 SM-N9005 and I want to get a Note 5 ROM or something new and flashy.
I want to keep the stylus functionality and a new camera would be neat too.
Could someone give me a quick rundown of what I need to do? (Root method? Bootloaders? Kernels? Which ROM? Patches? Xposed?)
Sorry, I'm so lost.
PS. I don't care about knox.
Would be better if you ask, if somebody can come to your place and flash your phone for you.
What you're asking for, is really the minimum basic knowledge you should have to flash your device.
And if you didn't get it from the numerous explanations and tutorials on the Web, will you get it now ?
I'm sure, someone will spoon feed you with the information, but will you then manage not to brick your device ?
You have some serious reading to do to catch up.
Good luck.
Actually as you can see I've been a member here for many many years and have rooted many phones and mod all kinds of electronics as well as many many other things.
It's not a matter of not knowing or bothering to do the research it's simply a matter of not having time at the moment. I have so many other things taking up my time I just thought someone could save me and anyone else who has been waiting for a good rom some time with a brief rundown on what they've found is best.
I'd love to try out all the different recoveries, roms, kernels et all but like I said, no time.
Android Development Darklord port .
Sorry no time for further .
Thank you that's the one I'd been watching but it's been on 2.1 for a fair while, perhaps with camera issues (op says so but people in the 1000+ page thread seem to say it's fixed? ) and every second post seems to mention some new fix or kernel required. Also I noticed there are some other note 5 ports now.

Developers, we need your help

Many people are looking for a smartphone with a great cost-benefit and able to meet all our needs. Sincerely? The answer for many would be the Mido. But there are a lot of people who need a more portable smartphone, which can be handled with just one hand without problems. These people decided to bet on the Redmi 4 Prime, which has practically the same characteristics and very similar parts. However, its development was not as great as its bigger brother, and recently one of the top developers abandoned the device, leaving a lack of content. So, I come to you, to that you kindly port some ROMs from the very similar brother to our smartphone. I think we will give you all the attention you deserve, because only those who do not have something know the true importance of things.

+1 , would love to see some of the greatest developers on Mido working on the Redmi 4 Prime !

That would be a relief for thousands of Redmi4 Primes and their owners!!
Really?u came here to request redmi note 4 developers to port rom for redmi 4 prime,with ur funny reason of one hand usability.Sry but developers of redmi note 4 not only work for its roms but also updating it frequently and now with android o's arrival do u really expect anyone to help u out?.The only people who can help you all are redmi 4 prime user themselves
You should be able to easily port Mido ROM's as it's same SoC, weird that nobody has tried it.
+1.
How many threads like this we will see in Redmi Note 4 section?
I can understand ask for help to fix some bug but not request to port whole rom to different device. If you think that is easy because they are "similar", then port by your own rom from Mido to your device.
I think it's not a real request that just somebody build roms for the RM4P.
Problem is that the RM4P wont be supported very good in future because xiaomi just pulled it from the market (nougat update is not shure)
I think it would be very very useful to get a clear view on which source parts can be used for both smartphones.
Could result in some very nice sinergy effects. TBH RM4P would gain a lot more out of it... but who knows
I think there is no reason to keep device development separted when the devices are so similar
And TBH #2: I can clearly see where your restrains come from. A lot of xiaomi users are just whining all the time. Its like a bunch of kids (anybody who knows the miui.com forum might know what Im talking about)
But it would be really sad if we would miss the opportunity for sharing/caring for our two devices because of that

Well, we need to have at least a kernel to make a good kernel for use so dev can make at least one rom possible if possible, I know it's difficult to carry a ROM for a smartphone that you do not have, imagine making a ROM without knowing it , I would do it if I had conditions and knowledge about but I do not have, so we are asking for help we want at least an official 100% functional ROM
c'mon dude... what's wrong with those r4p guys that jusk ask for help...
if you can't help them better to be quiet instead of insulting them or asking them to go away...
btw for r4p guys:
I think it will be very hard dude... yes, our device share same SoC (Snapdragon 625)
but I've look into it, we have different display, touch module, camera...
there is other components too like fingerprint, modem, wifi, bluetooth, battery, etc... I'm not sure it's same between r4p and rn4.
You could try to flash one of the kernel or even rom here, but it's very dangerous and I think no one want to take the risk
It'd be great help if any developer can build a stable kernel for markw out of mido. R4p's own kernel source can help with that.
I am also a redmi 4 prime user and would love if there is something that could be done.

we ask for your help since you're a bigger community. and you have like 5 official ROM's, and we have none. if you don't know, our dev @Razziell quit because he hadn't enough money to continue. his sources are good, so if you want to help its not from scratch - we have his sources.
unfortunately r4p community doesn't have many devs(if at all) to do this job.
maybe if one dev from here talk with Razziell or help him , he might convince him to stay.
we really sorry to bother you guys with those threads, but understand our situation

You do not need to talk about things you do not know. I had problems with the hard drive and only some people from the Russian community helped them to solve. For them, I continue to work. The rest can freely use my source, they are completely working.

You have problem with HD? Why didn't say that in R4P forums, you just say that you want to stop developing because you don't have time to do it. Is that whole reson to stop sharing with R4P community ?
C'mon guys!!!
Any good dev out here?? We have a good kernel.
Not fair that Note 4x as more roms and his little brother don't!! <3

Why not fair? Unfair is your stipulation and pretensions. Its simple: more popular device = more devs = more custom roms.
This thread should be closed because if devs will want to help - they will and pretensions like above will not change anything.
I recommend you guys start taking the initiative and learn to build the kernel yourselves.

Samsung Galaxy Tab 4 (SM-T230/SM-T230NU) ROM Development (Help Needed)

Dear owners of the 2014 degas/wifi tablets, a team is forming to help make your old device run like new again. We unfortunately may not be able to guarantee an Android version upgrade but a performance upgrade instead. Now, as of the last year or so, there has been a group (Will not be named for reasons) claiming they have been creating ROMs for the device that are new editions of Android or similar to the newer versions. I’m here to say that they have been deceiving you the entire time. But this forthcoming team will not do so and will give the 4-year-old tab some love like it needed a long time ago.
Though, unfortunately, the team being assembled only has two members at the moment. We are in need of more experienced/inexperienced people to help develop this upcoming ROM/s. Though, if this isn’t your thing but you have a tab to help with testing, that would be an excellent help to us as well.
Some criteria for people applying is:
+ You own or have a SM-T230/NU tablet that you will have for the entirety of your assistance
+ You have your own PC to help develop (Or if testing, have a PC to flash the ROMs onto your device)
+ When developing, the latest version of Xubuntu (18.04, Bionic Beaver) is highly recommended to install in order to help us. (If you have any questions if your PC specs are good enough for development, please message me.)
+ You have a Discord or are willing to create one in order to communicate with us. (XDA doesn’t have voice chat and would be too slow for this kind of development)
We will be actually developing ROMs/mods for this tablet. Not taking others work and making slight adjustments and then claiming it to be ours! That is stealing and that is not what our group is about. If you have any questions about anything in this post, please comment below or message me.
I've tab for testing, but unfortunately that is where my skills end.
That’s alright!
Please message me privately so I can set you up with helping us further with this.
Moderator Edit:
All "discussions" must be kept on XDA and in public - collaboration happens here.. Or use our Discord Channel...
Thanks
I own a Samsung Galaxy Tab 4 7.0 inch SM-T230NU and can help with testing ROMs or whatever you need. I can help just let me know...
I have Samsung tab 4 Sm-t239 I want to install marshmallow.....presently tab is having android kit kat 4.4.4.....can anybody help
Thanks in advance
So do I
I have a SM-T230 so I can help with testing, I'm pretty inexperienced but I can help a bit
I also have SM-T230, I would really like to have Android 5 on it so I can help
Is this development still ongoing? I would like to join the team. Is the discord still around?
