Samsung Galaxy Tab 4 (SM-T230/SM-T230NU) ROM Development (Help Needed) - Galaxy Tab 4 Q&A, Help & Troubleshooting

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?

I posted this in the XP forum as I know a few people there who have this tablet. I do not know if they follow the Galaxy Tab forum. My hope was to make this petition known in the XP forum in hopes it would be noticed and get the signatures to needs to hopefully get Samsung to hear its customers.

[BOUNTY] Nexus 9 for Cpasjuste

Hi !
I'm Cpasjuste, a long term user/developper on XDA. As many of you probably, i'm very interested in this device but i'm (really) lacking the founds to get one.
I'm not sure if it's something to do, requesting a bounty/device for myself but well .. who know ...
So i'm wondering if some people, or maybe a generous donator, would be interested in supporting me to get this device. I'm used to nvidia devices since the tegra/tegra2 and recently ported CM11 to a Tegra 4i device (https://github.com/Cpasjuste/device_nvidia_s8515), which i'm the only one if i'm correct. I think i could really help the development on this awesome device.
If some people are interested then we will setup something.
Thanks in advance for your time,
Cpasjuste.
I'm sorry but these type of threads are not allowed. You may use our built-in donation link feature.

Galaxy Note 10.1 2014 Exynos Developer Device

Hello everyone,
most of you probably don't know me since I did not develop for Samsung devices for quite some time now.
I would be interested in aiding the Exynos 5420 development scene (in particular on the Galaxy Note 10.1) and prepare a custom Android distribution for it (Team EOS 5.0 - Lollipop).
I can get all the required drivers and binaries I need for development, since most of it is open source luckily.
And the Nexus 10 (manta) can still be used as reference for many things.
All I need is a development device to debug on.
It is particularly important that this is the Galaxy Note 10.1 EXYNOS (WiFi-only variant), and not the LTE (Qualcomm) variant.
I created this thread to ask whether someone has a spare device lying around, maybe because of the little development on Exynos 5 devices, or if people would be willing to donate a device (I'm a university student and unfortunately can not afford the full price for a new device. I'm willing to dive into the Exynos development scene and spend time on this device though, including extensive debugging).
You can leave a reply in this thread or contact me on gmail: [email protected]
I have a better idea. Sending device is a problem. But we can donate to you, and then u can purchase P600 or P601 on SWAPA or EBAY. not new but fully working
I would be glad to see working AOSP/MAHDI or other ROMs runnig on my P601
Yeah, that was the initial idea.
I would pay any shipping costs or parts of a device (a used one is perfectly fine).
The issue I see is that probably not enough people willing to donate enough small amounts of money, hence I asked if someone had a spare device I could buy or pay the shipping costs.

I think it would be better to ask for donations because there is not a lot of people here although it would be hard. There have been previous instances where at least 2 different devs raised donations for this device before stopping development shortly after so people do have some trust issues. It would take a while but i'm sure people would donate considering you are offering an AOSP experience. If you renamed this thread to something like: Donations needed for new device- AOSP rom development. Then it would catch a lot of eyes because that's what a lot of people want The question remains whether people would actually donate. The average cost for you would be around 250-300 euros I think. That means you would need around 28 people (10 each). Whatever way you decide to go down, I wish you luck and I look forward to any rom developments if you do manage to get the device :good:
You seem to have quite a respectable history (in both Rom & kernel developement), so I think getting enough donations should be doable (and I'd be willing to donate a few bucks myself)
But I do have a few questions:
1) What about warranty? Some devs who had collected donations for a (used) device, have bricked their devices -> no more developement
Therefore P600 owners might be scared / hard to convince
2) what exactly is "Team EOS 5.0" and what makes it different from other Roms? Would you perhaps consider developing other Roms / kernels as well? (like porting over PA for example?)
Or would you maybe consider becoming the official P600 CyanogenMod maintainer (since we don't have one, yet)? [<- I think this one would be reason enough to donate]
Last but not least:
You could ask one of the XDA members who managed the previous donation-collections for help (they have successfully done it before, so they might be able to do it again :fingers-crossed: )
PS: The Note 10.1 2014 is great for college, trust me - I'm a student, too . All you need is the Papyrus-App from the Play Store.
Thank you two for your reasonable thoughts.
I think the main reason why the previous developers stopped developing for this device rather quickly is the Exynos chip.
The main difference between me and anyone else is (or so I believe) the fact that I am especially interested in developing for the Exynos 5420 chip and the drivers for it (mainly from the Insignal forum source).
As far as bricked devices, I can say I had a Samsung device before, and as long as the bootloader is unlockable and access to ODIN (The firmware flashing tool) is granted, a hard brick is rather hard to achieve. I see little risk here, and I assume my previous development experience will prevent me from making major mistakes in that regard.
A new device would cost me approximately 350€, so if we could collect about 300$ with donations (which would equal something like 270€), I'd pay the remaining costs.
People are of course free to check my development history and/or references first and see if they think I would benefit the aosp development scene for this device.
The ROM I mentioned (Team EOS 5.0 lollipop) is essentially AOSP 5.0 with selected features that we code ourselves, like EOS Weather, or the NX gesture interface.
If people however see the need for an official CM maintainer, I'd be happy to become this as well, all I need is a device to debug and develop on, I'd be willing to spend the time to officially maintain this device.
Other developers and/or contributors should also expect support from me in areas of kernel development or AOSP custom ROM development. I believe in 'sharing is caring', so all my knowledge and achievements on this device shall benefit the community.
If some of you could maybe contact the people who raised donations before, I'd be thankful and gratious for the support. All donations will be listed here and the whole process shall be as transparent as possible.

Hi. Here's the most recent donation thread which was successful :good:
http://forum.xda-developers.com/showthread.php?t=2742793
I don't see why another thread is needed though. I don't mind opening one up for you but you might as well use this one if you just rename it and state your intentions in the op.

Okay, so if maybe one of you guys, with good contact to the community, could open a new donatiion thread to collect the ~300$, I'd be grateful.
Or maybe @drrasii could chime in here and edit his first donation thread and link here as a reference to let people know what I want to do.
As I said above, I'd be willing to become the official CM maintainer, or if CM refuses to accept this for some reason, I'd host the needed sources for the device on my personal GitHub and keep it updated so people can build whatever ROM they want.
Of course, the first goal would be to get Lollipop running on this tablet, which I'd start with as soon as the device is ordered/has arrived.
Hey guys. That donation thread I started a while ago was on a whim cause I wanted Hyperdrive by sbreen on my Note. Was lucky enough to have him commit and get enough people chipping in for the tablet which was met with success. I'm by no means a great organizer or somebody with tight connections here on XDA . Probably would be best if someone who wanted to head it up would start a new thread stating the case.
Best of luck!

Thanks for the quick answer.
Could one of you guys (@22sl22 or @r4yN) then open a new donation thread and explain a bit about this thread and my plans?
If we manage to handle this process rather quickly, people should be able to enjoy L on this tablet soon hopefully.

Sure, i'll open one now :good:
I'll also post a message in here after the new thread has been created so that people know http://forum.xda-developers.com/galaxy-note-10-2014/general/rumours-plans-to-android-5-0-t2861225
EDIT: before I open the thread, how much do you actually need? $300 is about 240 Euros, not 270 so we will need a bit more, say $350, would that be OK?
Thank you very much.
Actually, 300$ (240$) is enough, I'd be willing to pay the other 100€ myself if it needs to be.
I want to get started rather quickly and have L running on this device, so I'd order the device as soon as the 300$ are collected.
Why a P600 model and not the P601 model?
The p601 to develop is exactly the same from p600 plus the phone side.
Sent from my SM-P601 using XDA Free mobile app
Why the delay? Here are the first 10 €!

Hi RaymanFX!
Glad to see that a real dev wants to take our device and port CM11 for us.
I do not make many words, but simply push the first $ 12.12 to you.
That's the current rates for 10, -€.
Hope it works as good as for sbreen (dev from HyperdriveRom) and many people jumps like lemmings behind me. :good: Haha!
Hope also we get the money quickly together and will try to continue to encourage people to make a small donation.
10,-€

Hey RaymanFX, excited for asop 5.0 but curious about some of the stock features that make this tablet. Is there any way to preserve multi window support or s-pen features ?

Apology to AT&T Galaxy Note 3 users

I know this thread will probably get shut down quick, so I'll keep it simple. Some of you may remember that I created a thread for a ROM entitled ENCOREROM and did not follow through with a release. I would like to apologize for that and explain a little. I have been an avid ROM flasher and seeker of knowledge in the field of Android development for some time now. When I set off to build a ROM for the Note 3, I was unaware of just how much time it would take. I was in high school, both regular and an extended hours performing arts school, and found myself with very little time to work on development. I have since moved on to college and am attempting to reach out and work more on my development skills. I have reached out to a fellow new dev that is attempting to do something that I attempted a while back, Android Wear for the original Galaxy Gear. I know I haven't always been the most reliable, but I try my best to share, learn, and teach where I can. I thank every member of XDA for this amazing site and hope that my past mistake will be forgiven. If you have any input on the Android Wear for Galaxy Gear, PM me and I will pass it along. If you have any information that may help in my learning, also PM me. Mods, if this is out of place, feel free to shut the thread down immediately. I no longer own a Galaxy Note 3 (currently on an LG G3). Happy New Year everyone, I wish you luck in all of your endeavors.
Thanks for the explanation...
Happy New Year!

Questions about Exynos and Android development

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.
