Topics and questions regarding compiling AOSP based Roms vs other sources like CM

I have decided to rework the thread to ovoid any confusion as the intent of posting this thread was to ask questions about compiling custom Roms from AOSP source that someone like myself who gained their development experience on other devices that building from pure AOSP code was not an option and are not as familiar working with AOSP. In the past my own experience comes from using and modifying for example the Cyanogenmod source so after attempting to now base my Rom on AOSP this time around with Lollipop have run into a few unfamiliar differences. As each question or topic is addressed I will update the Op. The hope is not only will I find solutions or answers to my own questions but that others in the same position will also be able to find use of the discussions posted in this thread.
Compiling the AOSP source into a format that can be safely flashed using a custom recovery. This was a 3 part question the first was just simply how to compile AOSP in a format other then .img files that can be flashed using a custom recovery without the need of flashing through fastboot or needing to use the adb sideload option.
1, Compiling AOSP into the for of an update.zip.
This was answered in short by know.patience by suggesting to use the “make otapackage” command in place of "make" to start the build. Was also made aware that a few modifications would need to be made to avoid producing an update package that does not use the new block format but instead the old style zips we are most used to seeing.
2, Now can create an update.zip using the “make otapackage” command ran into an issue that by flashing the update.zip produced would in the process replace the custom recovery used to flash with the Nexus Stock recovery. This was answered by Lethargy who suggested and provided a Link for the following commit.
For getting rid of the AOSP recovery:
https://github.com/Lethargy/android_build/commit/48521e167c642db76c9d4f52b1c63f9abc7f707f
https://github.com/Lethargy/android_build/commit/1d9224bd45ef2b4f5601a157de2bfe3bb1c95558
3, Now can create an update.zip using the “make otapackage” and after applying the above commit are now able to flash the update.zip without replacing the recovery Lethargy also provided links for the following commits.
To get rid of the block-based zip format:
https://github.com/Lethargy/android_build/commit/4d458300d935a3a9d893a590286cb578dcf54db2
You'll also want to make sure you have this commit so it doesn't flash awfully slow in recovery (8~ minutes, but only around 1-2 minutes with this commit):
https://github.com/Lethargy/android_system_extras/commit/52f8d5fc3edfacd112827d0a41516c1dc5f4a468

Compiling using the AOSP Master branch vs release branches. In following the directions provided on the Google development site are given the command for downloading the source code using the Master branch. Using the Master branch as apposed to a release branch such as android-5.0.2_r1 or lower have found that the source compiles just fine but have run into one issue and just a general question that a little explanation would be helpful for general understanding of the AOSP Master branch.
The issue is that after flashing a Rom compiled using the Master branch everything in the Rom works as expected other than the radio. I have so far using the same exact vendor blobs as compiling a release branch have not had a signal and baseband version is listed under about phone as unknown.
The general question is that the android version listed compiling a Rom using the Master branch is version 5.0.50.50.50.50. In general I have yet to understand what this version number represents and very little to no information available via the Google Box.
Between the both I now wounder if the Master branch is intended for actual use or if so what changes are required so the baseband version is recognized and radio / Ril will work?
Quick Answer:
Google first commits new code into master and then is later tagged with an update for realease so in generall many things can be broken and the master branch is and not intended to be stable so if building from master expect that things will be broke or buggy.
Compiling Rom and Kernel together. For those of us again used to compiling using say the CM code are now used to compiling the Kernel along with the rest of the code. I know it is easy to just compile the Kernel and include in the device tree but for those of us who would still like the Kernel compiles with the rest of the code there is no information available on the Google Developers site for doing so and there seems to be a few differences as have tried just using the lines used in the CM Hammerhead device repository. I have come across these commits from Cl3Kener that should help. Hate posting other developers code but is on Github so is there for the public at large. So far have only tested as is so will update if finding not all changes are necessary or can be modified.

Adding Pre-Built APK's
Seems Sprint users need a few apk's for updating prl and what not that are included into the Stock release but are not part of the AOSP code. For some reason through vendor or even device have tried adding these apk's into the build. First try I created a sprint vendor section and received a few errors untill learning would need to add sprint into a vendor white list found in build. Will post link to file later. After found the extra "Services.jar" I found in the stock image not found in the aosp compiled Rom did copy into the build but the apk's had not. Looking in the other vendor blobs noticed lge adds "qcrilmsgtunnel.apk" so followed the example and even tried just adding the other spk's into lge expanding the list used for adding in "qcrilmsgtunnel.apk" but still no luck. Also have tried adding through the device files for Hammerhead just to get them into the Rom for testing and still no luck. If this was CM or any other Rom not using pure aosp this would have been a 5 minut project so need to do some aditional homework.
Again think this thread could be a good resource for developers who are new to building their Roms around AOSP so wanted to include everything I run into during the process of moving away from using a heavily modified CM based code as the base of my Rom to using AOSP in its place so developers who are or in the same process or for those in the future can use as a resource to quickly adjusting. I have been building CM based Roms like Starship for years and after hours of working on other aspects to suddenly be stumped by these small differences between platforms can be very frustrating.

to the OP:
answer to your first question comes in two parts.
a) use 'make -j# otapackage' will generate a zip that is flashable in custom recovery.
b) if you plan on adding other files after the zip is made, you will need this info here:
https://github.com/android/platform_build/commit/26e6619c37e294fe2ee63aaa759e0ac861775ce8
There are some modifications needed to generate the OG zip files instead of the new "block" format.
Google hasn't released the 5.0.1 image for the N5 but that doesn't mean you can't build it and install it yourself. I'm running it and it seems okay to me so far although I'm hardly an expert.

I am building a customized AOSP Rom I am interested in sharing so was looking for help or direction in creating an update zip that can be flashed in a custom recovery like TWRP. I am not used to compiling AOSP and with the help of know.patience in the first reply am now able to compile an update.zip I can flash in TWRP but in doing so it also replaces TWRP with the Stock recovery. I have still been using the .img files to flash personally but am still trying to figure out how to solve the recovery replacement issue. I still have other features I am adding and testing before I would like to post my work but before I get to that point I still need to figure out my recovery replacement issue. Maybe using the words personal use may have been confusing but at the moment until ready I have only been using my work personally but would like to at some point post and share. I also have work that is not AOSP based I am sharing in the Android Development section but I have been building CM and other source based Roms and sharing for years. This is the first device I have been able to build AOSP and still have a few things to figure out before sharing any of my AOSP based work. I am otherwise not sure why you think these are questions for general Q&A.
I started this thread in Android Development as there was only about 4 posts in this section and I see many AOSP based Roms in Android Development who's developers obviously know the answers to my questions so tried to get away posting there in hope one of these developers could help or like in the first response point me in the direction of a commit before the thread was moved by a mod into this section. Do you think someone in the general Q&A section is better equipped to help answer questions about compiling an AOSP based Rom in the form of an update.zip that can be flashed in TWRP without also replacing TWRP with the Stock recovery?? Would also be nice knowing what changes in the code need to be made in compiling an old style update.zip that does not use the new block format. This would be a bonus but overall not %100 needed as instead of moving files around after the code has been compiled have added init.d support and first have all the files I want moved into a staging directory and then form an init,d bash script to move the files during first boot and remove those that are not needed like this example I used in my CM based version of the Rom I am trying to update for AOSP for 5.0.
https://github.com/Starship-Android/android_device_starship-common/blob/cm-11.0/app-update
https://github.com/Starship-Android/android_device_starship-common/blob/cm-11.0/cleanup
I must seriously be underestimating the knowledge and in general the types of questions being asked and answered in the general Q&A section.
Honestly if not for the amount of times thanked I would think this comment was not so much about helping or community but more about someone trying to puff themselves up by trying to appear important by making decisions about what questions are worthy of being asked but judging by the number of times they have been helpful I am thinking its either a case of not reading or understanding the question being asked or my own inability to express my questions in the proper manor. Either way its definitely not about taking up resources in a section with less than 10 total posts. The frustrating part as a community as I like to believe we are all in is that why I worked on other parts in updating my Rom had expected that at least more than one developer out of all the AOSP based Roms posted in the development section would have helped me with this one part. Its not like I am asking how to be a developer just a resource to help with two simple things I am sure I could have figured out and will most likely still figure out without any help. Overall my thoughts behind posting this question was that why I am working to figure out something a bit more time consuming at least more than one person would be helpful enough to copy and past a commit.
XDA is weird in that with other devices all the developers would join a team and start a shared group of repository’s for one another to use in trying to make the best possible experience and options for everyone. For example in the op I posted an example of hours of work I did showing what libraries are needed by one another just so others could use it also in trying to port as much as possible for in that case the Galaxy Mini. Then with other devices like seems to be the case with the N5 its all about competition and what I am starting to call the smartest person in the room syndrome. Its just a shame there are only 5 maybe 6 threads posted in this section and I think that says allot about the community in general. So many good things could come about if we just tried to be helpful and pull as much knowledge together as we could. Anyhow think its time for ending this rant.

Thank you this is well beyond what I was looking for and don’t worry I make it a point not to send out PM's with questions that can be helpful for others as well. Otherwise would have blown up the AOSP Rom posters in development but thanks for the information.

If you mean "I'll probably ignore you if you try asking for support over PM.", that's part of my forum signature.
If you need anything else feel free to @‬‬mention me in a thread, though.

I reworked the Op to avoid confusion as Mods have been moving the thread around into different sections. I personalty believe these questions are more geared towered development than general Q&A but at least at the moment I appear to be wrong about that. Never know though as in the past one day one of the mods may decide to move the thread back into its intended location but until then I guess these topics will be of better use to general users than developers.

You should include the other commit (https://github.com/Lethargy/android_build/commit/1d9224bd45ef2b4f5601a157de2bfe3bb1c95558) which fixes building since the first one results in "IndentationError: unexpected indent".

Thanks for the heads up, when testing these I also cherry picked a few other things that looked related. Have to double check but may have forked the repository’s from you so would receive credit if anyone decided to look over my repository’s. Well overall my personal Github has been pretty bare as in the past most work was done on more obscure Virgin Mobile devices with only a few developers so we would pretty much create an organization for all the developers to use.

Have 2 other members listed who I had worked with in the past but has otherwise been a solo organization with one of the other members who decided on going with the Moto X and Verizon over the N5 and showed little interest in his 2012 version of the N7 as it was intended for being a Nexus only device line up and the second being my Kernel Guru from a few devices back who mainly joined to help me out with a few things but ultimately what I am getting around to is this is the first time working %100 solo. Have to say without having anyone to bounce off ideas and share findings with things definitely move much slower and take a bit of getting used to. Is also the reason for starting threads like this. Most of this stuff looking in the developer section appeared to be pretty common knowledge but having never worked from pure AOSP before was slowing down other development for about a week just to figure out what seemed like half the community had already known and with what probably took at the most 5 or 10 minutes of copying and pasting commits probably saved me a weekend of sifting through github and testing. I hope by creating a thread like this will be able to do the same for others.

Hi guys,
Anyone manage to fix RIL problems with master branch?
I also build AOSP roms so for sure i will hangout here

ODEXED
i am successfully build cm12 with fully odexed. now i like to odex some prebuilt apk also but LOCAL_DEX_PREOPT=true not odexing prebuilt apk. can somebody help me? already DEX_PREOPT=true working fine.

Why do you need to odex a prebuilt apk?
Not sure if what you want is even possible.
But if odexing your prebuilt apk is necessary then why not odex it then include the .odex with the prebuilt?

Nothing so far, I downloaded the master and 5.0.2_r1 branches and have loaded both in meld for looking over differences but have not yet identified from the dif between the 2 branches that is responsible for ril working in release branch but not master. Still have allot to look over though still. Still have not found a decent explanation of the master branch to know if its recommended to build from but still just for Knowledge sake am interested in knowing. At first thought maybe apn's but not so sure with baseband also listed as unknown from my Master branch builds.

As far as i know all the patches goes to master branch then from this branch ,if they are ok,is distributed to lower branches.I also didn't find info why is named as 5.0.50.50.I will try to investigate this ril problem

Thanks will definitely update the Op with any findings. Was very surprised to find the thread again as it has now been moved 4 times by 4 different Mods, some bounce it to general Q&A and then is bounced back here by another. I understand its not comprised of the most advanced development topics but with that said is still way more advanced than the topics being discussed by general users over in the general Q&A section. I had just thought it would be a nice one stop place for learning the basics of AOSP development. With the constant moving and scolding messages being received one would think the threads very existence is up there with crossing the streams and threatens the existence of Android development.

@chairshot215 Thank you for starting this thread. Thank you @Lethargy for all of your insight. I like to do my own perosnal builds every once in a while for my nexus devices. What I have observed over the years is that the Master Branch will sometimes have funky version numbers like you have described. One thing to consider is what @malcho mentioned. If all commits indeed go there first before the respective branches(although this may not entirely be the case), then it is likely that some things may be broken in the master branch from time to time, hence the ril problem. I think with the galaxy nexus I ended up running into issues from time to time with the master branch, and from there learned to build for specific branches/tags. For instance, there are times when items within a specific branch will be ahead of master in some areas and behind it in others, as in this link to platform_build for lollipop release https://github.com/android/platform_build/tree/lollipop-release. So with that, it is probably in our best interests to just use specific branches.

Thanks for the response and have definitely learned its better building from branches with a release tag. Still very curious why and how the branches are structured so thanks for the explanations.

Way totally off topic for the thread but landed a brand new SSD and decided to install everything fresh. After everything was set back up and wanted to start building I ran my usual,
-j'grep 'processor' /proc/cpuinfo | wc -l'
a very old habit before fully understanding what number to use after -j so used grep to figure it out based on Googles recommendation. The command did not work so removed the grep and just made it -j4 but also with 0 success. At first just figued I missed somthing setting everything back up and "make" is just not working but wrong again as running "make" command without -j of any number works just fine.
Also tried this with CM12 as I am doing 2 versions of my Starship Rom. One from AOSP and one using CM. Figured AOSP would be special for Nexus users why also having a version for CM I can make most changes by adding a Starship Device Tree could easily port the Rom to any device running CM supported or not.
https://github.com/Starship-Android/android_device_starship-common/tree/cm-12.0
Also found why compiling CM that -j also results in an error
Invalid lunch combo: cm_hammerhead--j4
No such item in brunch menu. Try 'breakfast'
So far have not found anything using the Google Box so figured may as well ask. If have not figured out by now I have no shame in asking questions. Oddly enough that is for things that are probably relatively simple. Took a better part of a week figuring out how to start CM using the Now Launcher and setting up init.d bash scripts for moving around and replacing libs after learning the Gapps package includes libs that will not work so the solution needed to be that the CM Gapps package libs needed to be replaced with either stock or libs pulled after installing the Now Launcher from the Play Store after flashing Gapps and the Rom staring. Also then what if user updates and wipes the system partition after the new and updated llibs have been moved into place. Anyhow point of story is things like this I will just figure out without bothering anyone but for the cant believe I need to stop what I am working on to figure out something most likely very simple and can be answered with very little time spent I have no shame in just asking. Not that someone else’s time is less important but like I have mentioned before is frustrating just after spending hours or days figuring out something asked in dozens of threads is just frustrating getting caught up or loosing momentum and thought processes over something so simple there are little resources available. Also I assume most devs have the same experience when you have an idea or thought behind resolving an issue that once you stop and change direction it just sometimes never comes back and that short time you had I guess can be called an epiphany is gone once going back. Otherwise thats how I justify asking dumb ars questions.

[DEV][G925F] CyanogenMod 12.1 Development

Hello there, it's time to get this rolling somewhere.
This is a Development-Thread. Please don't post if you aren't a developer.
What this IS
This is a Development thread, a platform for developers to discuss the development of CyanogenMod for the G925F. It's made so that we can get this working, fix up the problems - because there will be severe ones - and achieve a working official Rom at some point.
At the moment it's @OldDroid and me with help, but it would be awesome if interested devs would join in so that we can make this a team effort.
In short, it's a Dev-Thread in a dev section.
Right now it doesn't work and I'm not sure that it will work.
What this IS NOT
This is NOT a working Rom. Not even close. I can only link you to the kernel repo and soon to device and vendor, as they are almost completed for a first try.
And yes, there is no download link for the Rom. Because there isn't anything you could download yet.
This is also NOT intended as a Q&A thread. Please don't ask if your variant will be supported, I will respond by trolling. Firstand only priority is to get this running, then we'll talk about variants.
And ETA is an evil word with no meaning here. I work slowly, deal with it
Where are we currently?
Much further than a day ago
Thanks to @OldDroid, we've teamed up

It's apparently not without some minor casualties, but we got it. Huge thanks to @RaymanFX, he's helping me, since I'm not that much into CM building yet and I'm also basing this project on his CM for the N910C, which's 5433 is darn similar to our 7420, so we got a pretty good base to begin with.

What do you mean "killed"? Killed the chip or wiped the MAC addr. or something?

I'm currently building the Rom with completely removed Bluetooth support

First Build is compiled and ready for a test.. But I can't install the zip. This would be hillarious if it wasn't so annoying

I think that there was a mistake in the partition sizes.. /system was declared as 4.1GB, but it's only 3.6GB. Recompiling with a new value, should be able to flash it then

Good luck develop without documentation for exynos chipset.
But can you tell us more in details how porting works and what are the challenges with it.
Is it hard to develop a rom without samsung binary files and drivers? I know they are proprietary and closed soruce.
If just Samsung could be more developer friendly like Sony.
We can request source for closed binaries here, http://opensource.samsung.com/reception/receptionSub.do?method=inquiryView, most likely they wont answer

The lack of drivers makes this a fun exercise almost Where's be the challenge if everything was easy...?

I can't say what the challenges here will be, since I couldn't manage to even flash it yet - Second build is compiling since hours now. For now it's using all the proprietrary stuff we managed to grab and some additional stuff from the 5433 CM. But without booting it's hard to tell what won't work and might present a challenge ^^ From what I saw it'll be tough to just get the modem running. The hard part is to write the drivers yourself

It's interesting that you can use drivers from 5433, which is a 32bit platform. Most drivers are not compatible when you switch from 32bit to 64bit if I am right?

As a base to know how to do it, obviously we can't just use drivers for a different chipset

Updated the /system size in the BoardConfig and at least it flashes. But it doesn't want to boot for some reason yet.

If you have the 5.1.1 boot loader and are using 5.0.2 as a base. Sboot will not boot it. As a fyi. It checks Linux versions.

Both is 5.1.1 and Sboot seems to clear the boot as well, everything seems to go fine, it just doesn't boot. :/ Trying with building the kernel during the build itself instead of using a prebuilt one and see how that goes

I would personally flash an Engineering boot loader while doing this, to ensure version checking is not the issue.

That was really not all that great of an instruction on how to get started with rom building because for 1 unless you have a really super fast computer trying to do that in a VMWARE is going to take forever because the first compile and build takes hours upon hours I'm not kidding when I said you needed to download the entire CyanogenMod or AOSP source code and apparently from all the changes people have made its up over 13GB which is huge mind you the first build is going to give quite a few errors which you'll need to fix by going into your github and making changes to the specific file that needs changing and then repo sync or just change it on your local computer first then push it to github.. You did fork the device tree to your own github right? Then you have to download the device tree source to your local pc in order to even begin building anything. They also need to be in the correct spot by the way or the build is gonna throw an error that it can't find / or so and so doesn't exist.. By the way the 3 device tree files you're gonna need are "Device, Vendor and Kernel.."..

Yes, everything you said is correct. I was only giving him a starting point. I know that porting, in this case patching, is a lot more easier than building, if done properly. If he wants to build and to learn a lot of stuff I personally advice him to follow your advice.
But in the end it's up to him. At least now he has two starting points. :highfive:

That's true, 2 starting points is better than none.. I don't necessarily like "patching" others work because you never really know how they made it or if it has problems which is why I just start from scratch.

Yes starting from scratch was initially what i wanted but i looked around on XDA university for a week and that helped get me to learn about setting up Vm, installing android sdk through terminal ETC and repo init repo sync, downloading repositories and other source codes.....BUT my thing is wanting to learn how patch errors and need more on hands experience for setting up build environment

[ABANDONED] MIUI 8 For Huawei P8Lite ALE-L21

--FOR MORE INFO AND NEWS ALWAYS CHECK MY LAST REPLY!--
Thanks for understanding!
PROJECT IS ABANDONED.
Regards,

Holy ****, finally. I cant try it out for my self cause i need to leave to malta tomorrow but i can try it later

MIUI Rom, finally!!!!
I hope they fix the bug as soon as possible

Again, the ROM is NOT bootable, I need logcats from you to fix the problem, hopefully.
So don't expect this to boot.
Thanks for understanding!

Try to take a look here Logcats
I hope to have helped

Thank you.

Thank you for your logcats. I will see what I can do.

How does it go with progress?

Should boot if you use custom kernel and copy&replace blobs

I am giving up on trying to fix that error message. I am trying to build AOSP 6 and then try again patchtom, hopefully I won't get that error.

I know how to get miui booted, making aosp is not enough, there is changes you need to play with them like .rej files and boot.img too experienced on my old s2 plus i9105p. as I got stuck at animation boot.

MIUI ports were one of the most time-consuming ports. I'm not sure how does it look like today but I'm pretty sure it's identical to how it used to be. First you had to modify the ramdisk and then patch all java resourced and with a bit of luck you get bootable rom.
I'm really sick of seeing all those roms all based on 1 device tree which is not even fully functionall yet. People keep making "new" roms but all are actually the same, all have same list of non-working features. Just compiling different android distro with same device tree over and over.
XDA used to be place for original work and for people who put effort in their projects. Now kids keep spamming dev threads with copy&paste roms or useles threads.

Yeah. We have like 2 developers(one is a team) On this device. Haky and OpenKirin. And 6 "different" ROMs that all work the same, with the exception off the nougat FOMs, which have even more bugs.

I know man, I wasn't talking about you. I was talking in general. I know you're doing god work, despite I'm not developing anything since a long time I still read forum and follow what's happening.
Like @Vinnipinni said, 2 guys and 6 "different" roms. But all working the same.
Back in times people were more likely waiting for stable CM/AOSP before compiling bunch of other distros. Now it's just mess.
I really wish I could go back to developing for android devices, especially now when I have programming knowledge and experience.

Custom Roms/LineageOS on SM-T505

Hello, everyone.
I noticed, there are many custom roms, but not that many for the SM-T505. Is it because it's newly released, or are there other reasons?

Yes, this is a new device and many people are probably waiting for the Black Friday/Cyber Monday deals to grab one. I just grabbed one for $150 on Amazon, a steal compared to something like a Fire tablet IMO. This is a low-end tablet, so there won't be as much focus on it as say a flagship phone. But thankfully it's already been unlocked and rooted, so the next step will be to get TWRP on it, and then custom ROM development can start to pick up on it. Don't expect any updates before the end of the year for custom ROMs though, it will likely take time to have TWRP up and running on it, but I am hopeful that we will see good things on this tablet in 2021

Without kernel sources it won't happen. See https://opensource.samsung.com/uploadSearch?searchValue=sm-t505 and https://opensource.samsung.com/uploadSearch?searchValue=sm-t500.
You can request them on that page. I did it a few times but no response so far.

Just got an answer from Samsung, but don't get to excited. It was just an automated answer, that they received my inquiry. So stay tuned...

https://opensource.samsung.com/uploadSearch?searchValue=t500 gives you a 514mb file with kernel and vencor files.
Maybe both 505 and 500 are similiar enough to get you started

Sources are available: https://opensource.samsung.com/uploadSearch?searchValue=sm-t500
They include a toolchain in kernel tree, broken KConfigs and a lot of junk. I will try to clean a bit a mess and update a lean kernel tree to github

Sure, but I'm going to remove the toolchain from the kernel tree since the beginning. It takes About 1GB alone and I don't want to have it on git refs because it will still take a lot of space even if removed.
The rest of changes will be available on github.

It's been a long time, since i took up building custom roms and forgot about it for a while... if the kernel is cleansed from all the BS no one needs, that would be awesome.

There are a lot of small changes to comments and changes of 2 characters in a line. Wonder if they backported stuff there.

Kernel of the SM-T505 was just released...
If this is of any relevance, the download is 'just' 200MB... i wonder why.

The Platform Archive is mostly identical, just a few text files with notes and copyright were missing.
The Kernel Package as well, just small changes to netfilter and
a new defconfig file.
Defconfig for both devices also is more or less the same
gta4lwifi_eur_open_defconfig is missing one line compared to gta4l_eur_open_defconfig
CONFIG_SAMSUNG_FREECESS=y
Guess the difference comes from the toolchain mentioned above.

@paziusss
How far have you come?
Would be great if we had something clean to start a twrp and easier rooting

Sorry, I have a very bad internet connection (uplink it is ~50-100KiB/s)
I created the repo a month ago: https://github.com/pazos/android_kernel_samsung_gta4lwifi
,tried to push and failed. Never tried again until now, but it is still failing.
So, if somebody is nice enough to dump the contents of the SM-T500 kernel in a github repo, I can fork and submit the patches without having to upload the whole thing myself.
