Building from Cyanogem source and flash to atrix

Hello everybody,
I'm an Android app developer for some time, but from some time ago until now I have been tweaking the framework, trying to enhance, customize and maybe correcting bugs, so I'm working on the emulator, but I would like to test it on my device (Atrix).
Since I'm a newbie on this matters and I found plenty of threads and sites/blogs, I got a little confused on what are the steps to be made, specially because I would like to build from source as to have my modifications flashed. I'm aware of the hardware implications for my specific device, so I decided to use a reported working rom source code for my device, but i'm a little lost. I thoutgh to be using Cyanogem but I don't know the specifics.
Since I already have the source code AOSP, I think It would be painful to make it work on my device (drivers, kernel, so on...).
I just want (for now) see my framework modifications on device. Anyone could point me to the right direction?
I thought of using this firmware here.
Thank you all.

[Q] AOSP/CM on G935F

Hi, I'm kind new in creating stuff for my phones but I want to give a try and bring CM/AOSP (I know that they are totally different things) to our phones.
I've done a research and all that I found was that it wasn't possible because we haven't the kernel source. But now that it is available in the Samsumg Open Source page could we make that possible?
Thanks a lot!!

If u really did the research, u should know someone had made this before but unable to call success....

Yes, i did read that, but everything i found was this:
In the case of the S7/S7E because the SOC is either closed source (Exynos) or has a locked bootloader (Qualcomm). The former makes it very difficult to produce a Rom that approaches anything near being stable, the latter makes it literally impossible until the bootloader is unlocked, which is unlikely to happen.

But I can't understand why if we already got the kernel source. Can't we just modify the kernel to make a kind of "mask" that allows the ROM to use the hardware correctly?
Maybe I'm asking something really stupid, and if thats the case I'm sorry, but I really want to know why we fail in this and see if I can find a workaround

Start here: http://forum.xda-developers.com/s7-edge/development/cyanogenmod-13-galaxy-s7-edge-t3414697
Get the source, make a local_manifest.xml file, get the rest of the source, edit the source code and build a rom .
But before You try, I can already tell You that it will be extremely hard to do. I've got CM to compile (yeah, compiling is actually a HUGE step) on other devices and then eventually to boot. But it took couple of days of code fixing (which I at this point somehow understand but it's still quite a magic for me).
Couple of days ago I tried building CM 13 and 14 for S7 Edge and after a whole day of fixing code and stuff I gave up. The worst issues are "shared library, excludes, includes" thingys.

Anyone have resources for porting ROMs?

I've been wanting to get into porting ROMs, although I'm not too sure how to go about it. I have a few in mind I'd like to attempt to bring to our device. Does anyone have any resources/links/videos on how to go about porting? Everything would be greatly appreciated

Which ROMs do you have in mind? I might be able to help.
P.S: You can look in the LineageOS porting instructions for our device, if that's going to help you!

A few of the ones I've been thinking would be a good fit for this phone is the Pure Nexus Project, Slim7 (Want to get a fully working build of that going, love Slim7 haha), OmniRom, and lastly a MIUI port once I get the basics down.
I use macOS, but also have a virtual machine for both Windows 7 & 10 and Ubuntu and Fedora so any guides across any platforms help.

I know different ROMs use different structures for device trees, but here's a guide to compiling Lineage 14.1 to the G4 Play. This guide is made for Ubuntu 14.04/15.04/16.04, but Fedora might be able to work as well as long as you can get the proper packages installed during the prerequisite steps:
http://wiki.lineageos.org/harpia_build.html
It may not help much with other ROMs, since I'm not sure if the other ROMs support using CM/Lineage based device trees to build, but this will give you the basic instructions on how to download source, get the proprietary blobs/device tree you need, and compile everything to a working zip.
As for actually making device trees for other ROMs to use during compilation, that I don't know myself, and was never really able to find out.

I build on Fedora. If you're using Fedora 25, use these steps to set up a build environment: https://gist.github.com/sultanqasim/09f19221c67c71edd099eb86c6a92467

Port of lineageOS

Hello Guys,
Today I woke up with a new idea; I want to port LineageOS to the LG V20 version H990DS. I was tinkering with this idea for about one year, but never actually wanted to make the step. Until today. I used LineageOS and CyanogenMod since 2012.
The reason why I want to create the first port is because I have the time at the moment, so why not help the community? I do have four years of programming skills C/C++. Run Linux as daily driver etc... Do know how to use git, linux, autotools etc... The tricky part however is: I never compiled a Lineage OS rom from source and I don't think the compiling would be a problem, but the LG V20 H990DS isn't officially supported. My question is: Where do I start to program? How can I compile and build a working Lineage OS for the LG H990DS. Are there any good website I can read from?
I saw this:
https://www.youtube.com/watch?v=MGI3NSJFtKA&feature=youtu.be
https://forum.xda-developers.com/chef-central/android/how-to-build-lineageos-14-1-t3551484
http://www.lineageosrom.com/2017/01/how-to-build-lineageos-rom-for-any.html
https://www.reddit.com/r/LineageOS/comments/6iie9l/how_to_compile_lineage_os_141_for_unsupported/
https://www.reddit.com/r/LineageOS/comments/684qkp/help_noob_compile_lineageos/
So to make it easy: I want to program a working LineageOS for the LG H990DS, but don't have any understanding about where to start. I do have four years of programming skills, not so much, but know C and C++ well.
Thanks in advance,
Maurice
English isn't my native language, sorry for grammars.

someone help this man up.

Did you check the existing LineageOS thread?
https://forum.xda-developers.com/v20/development/dev-cm14-t3509953/post74550386#post74550386
If you want to help, I'd suggest asking him if there's anything you can do.

Thank you for your response. I do watch that thread, because I want lineageOS for the h990ds device. The problem however is that I don't want to jump right into the code. I want to know what I am doing with each line of code. At the moment I think I have to change some things in the kernel so that it can boot, but I don't know if that's true. And there is so many documentation about how to compile lineageOS, which I don't want to do. I want to program and compile lineageOS. Every tutorial skips the program parts and just compiles lineageOS.
So maybe a good programmer can give my some advice? Where to start and where can I find some documentation?
Best regards,
Maurice

Welcome!
First off, I recommend using Ubuntu 16.04 (I personally use 16.10 however). Be sure to follow the guide you linked from chef central carefully.
For the dual SIM variant, I don't believe any current source exists. Although with the similar hardware and if you have decent skills, you could get it going.
Take a look at the existing v20 trees:
V20-common: https://github.com/LineageOS/android_device_lge_v20-common
Msm8996-common: https://github.com/LineageOS/android_device_lge_msm8996-common
H918 (as a reference): https://github.com/LineageOS/android_device_lge_h918
Kernel: https://github.com/LineageOS/android_kernel_lge_msm8996
Vendor: https://github.com/TheMuppets/proprietary_vendor_lge
Those are the basics to check out. Now I did see someone converted the H918 tree to H990. Here's a link to that for reference: https://github.com/android-device-lge-h990/android_device_lge_h990
You will definitely need to make a custom defconfig in kernel sources. The device tree changes should be rather easy. You'll need to pull vendor files from stock and import the drivers and dts files from stock kernel source. If/when you get a working kernel and device trees there's a 99% chance you will need to Port other drivers and vendor files as stock files don't play nice in aosp. If I were you, I'd start looking through commit history on GitHub to see how the other devices we're brought up. That is how I learned everything.
Also, git will be your best friend when bringing up large projects, like kernel. Learn git, get comfortable with it. Cherry-picking and merging is what keeps us going.
Best of luck!

I suppose you could say there are dueling work-in-progress H990 trees since the other one is: https://github.com/x86cpu/android_device_lge_h990
The one you pointed to is mine. I was hoping for some collaboration with @x86cpu on there (in theory @x86cpu also has permissions to modify that repository, assuming I've set things up correctly). While the initial steps have been done, it is not finished! Some issues are left for getting LineageOS operational on H990 devices.
Of crucial note the modem fix in its current form is unacceptable to LineageOS (despite working). I've got two variants of one solution almost ready, but they're yet ready.

Thank you for your answer and I will look into it. I sure hope that I can help you some day, but first I want to understand the repository. After that I will help you both to code.
Really thank you and I will do my best to catch up with you.
As for the Ubuntu version. I personally use arch Linux (with plasma), because I like it more than Ubuntu. I don't think that's a problem and else I will compile the Ubuntu programs to arch. And I know my way around got. Use it for about 4 years now and now what merging/branching rebasing etc means and know how to use it.

Mainline N8000 Progress

Dear fellow developers and users of this great device,
I'm working on mainline support for the p4note device family, I started with the N8010 but this is usable on all the other N80XX devices as well as they are technically all the same aside from the modem.
The current status is that an initial device tree will land in 5.11 with some components still missing but its a good start. I'm working on the rest and also I'm working on Android 11 on top of that.
This post will not be updated any longer, you can find my mainline progress here.
There is also a blog which I'll probably woefully neglect as I'm way too busy with everything in life.
Cheers

An update for my mainline progress, there is kernel logs on the display now! I'm currently working on the touch screen config.

Oh Nice to see.
But i think not many people read the General forum anymore ^^
You might want to mention this in the Dev thread.

Do you have a git repository anywhere? I found a Note 10 8000 hidden in a box and wanted to get a working small working terminal up on the wall at my 3D-Printer/Soldering-workstation, I would be happy to be tinkering around som with the code.
Nevermind, found it.

Hey, great to hear that you want to tinker with it. Remember that I currently work on rev 6 of the hardware, the version info can be found in the atags of the kernel log. You may run into issues with other revisions but it should be fine.
For the wifi settings, you need the correct nvram file. I'm not yet sure whether you can determine it by the version of the hardware, the current way is a macloader in the current hardware repo.
I extracted the touchscreen firmware from the sources and put them in my buildroot repo. The driver will look for a file called maxtouch.fw on boot.
I hope this helps.

Thank you very much for the pointers, I haven't t really been into kernel development since Samsung Galaxy S2 (9100), but getting a proper Linux installation on this device would fit me perfectly so I would happily try things on my side, keep us posted.
