So i want to port ubuntu touch to our device. It has the mediatek mt8163 chipset which is also one of the amazon tablets at https://github.com/mt8163/android_device_amazon_karnak
it sounds like it will work for building the halium patched kernel so we can flash the gsi. Im looking for someone with more experience with building kernels and such to help make this possible. Im willing to so all the testing on my device since i dont mind bricking it.
I have 2 of these tablets... Bought at the exact same time... One of them has worked with multiple GSI's I've tested, the other hasn't worked with a single one. I'd love to help but I don't have the experience with what you're asking unfortunately

I thought I'd post here my (and the people who helped me) progress on porting MultiROM to the HTC Nexus 9.
Contributors (so far, tell me if I miss anyone)
@Bogdacutu for his port of MultiROM on the Shield Tablet (The arm stuff)
@USBhost for testing as well as helping with the patch (patch is still WIP, more on this later)
@Tasssadar for MultiROM all together
@Unjustified Dev for his influence
Progress
Working: Multirom TWRP has been successfully compiled for flounder and has working ADB and MTP.
Partially Working WIP: MultiROM boot selector source has been ported to work with arm64. The multirom boot selector compiles for flounder in zip format and launches at device boot. However, touch does not work and there is no ADB at the moment.
Not Working WIP: The kexec hardboot patch currently does not work so the Nexus 9 is currently unable to boot another ROM other than the primary one.
Source
All sources can be found here (I know some of them may not work and may be a little messy but this is still a work in progress)

Building Notes
I compile this with the CyanogenMod Device Tree. Instructionsfor building multirom can be found on the multirom wiki found here
Note: adbd and kexec-tools need to be replaced with these versions that are arm64 compatible

I might have found a repository that may help us out with the kexec hardboot patch on arm64.
There are many commits here that relate to kexec on arm64
Very glad to hear!! Sooper work :thumbup::thumbup: :beer:
This may also pose useful for the arm64 instructions
...
Looks like kexec-tools may need to have a lot of changes for arm64.
There are the changes made on a more recent version or android tools (not the one for android/multi-rom). I think this commit may be helpful but changes would have to be made.
Re-based many of the repositories on MR64 the other day. Now I need to test....
Also, the kexec tools function for flounder is completely re-written so maybe kexec will work?
I'll have to try to test when I have a lot of free time...
Is this going to work to get Linux kexecboot working? I really would like to have Linux running natively on this tablet....
Any updates on the project?
Any news on this, hoping for developments so that progress can be made for oneplus2 and multirom?
Thanks
Hello, and whether support for Nexus 9?

Is there any deving goin on on this? I think its way too hard. kexec isnt x64 compatible. (The binary itself isnt. How will youll port hardboot ) First we will have to add x64 support to that. I have seen your commits. That isnt x64 supported too.
Please update me on this, im building on op2 if this works. Thanks <3

I know you've put this project on hold for the time being, but I would like to jump in on this dev-tastic venture. I got a Nexus 9 (LTE) for Christmas*, and wanted to let you know that you don't have to bear the burden of building/testing/debugging/etc. all by yourself. I am fairly well versed in the mechanics of MultiROM, and have been (and still am) a user of MR on my Nexus 7 (2013) since v28 . . and honestly, without MR on my Nexus 7, I probably wouldn't have the pen. testing abilities that have enabled me to offer those additional services to my clients (i.e., security consultation, data breach prevention, etc.).
My point is that I owe a lot to Tasssadar and the "MultiROM for Android" concept in general, so I am happy to give back in any way that I can.
The Nexus 9 has been my dream Android device ever since the rumor mill was buzzing with notions of a Nexus tablet with an ARM v8 (ARM64) based Tegra variant!!
Let me know if/when you wanna get this thing off the ground again, and I'll make myself available as much as possible.
FULL DISCLOSURE: Although I am fairly versed regarding MultiROM and it's mechanics (kexec-hardboot, modifications to TWRP, etc.), I don't have much experience when it comes to ARM v8. However, I am pretty fluent regarding desktop x64 programming applications and coding, so it shouldn't be too hard for me to wrap my head around this whole ARM v8, 64-Bit SoC/MoP revolution. If you (or anyone who knows) could fill me in on the challenges we are facing regarding kexec and hardboot in a 64-bit scenario, that'd be swell. In the mean time, I will do my best to get up to speed regarding the repos & commits you have referenced/linked up to this point.
THANK YOU FOR ALL OF YOUR HARD WORK THUS FAR, AND LET'S GET 'ER DONE MY FRIENDS!!
:fingers-crossed:
*BEST . . CHRISTMAS . . PRESENT . . EVER!!!!!!
Thanks Mom!!
They have a Multirom version working for the Nexus 6P which is an arm64 device using the kexec method. Here is the link if it helps you devs.

yep, I ported it to clark already, maybe I'll try porting it to flounder in the future
Multirom for yureka aka tomato (64bit snapdragon 615) is also coming today with kexec-hardboot patch. Hope other devices also get this fast
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
I have been waiting quite some time for a custom rom for SM T819 but I haven't see much progress in this. I looked for a device with similar specs for our device and came across this device which already has a Lineage OS build available. Its practically the same device but with a different screen size.
LeEco Le 2 Specs: http://www.gsmarena.com/leeco_le_2-8053.php
LeEco Le 2 Lineage OS Github Repo: https://github.com/LineageOS/android_device_leeco_s2
It will be a good starting point as I think for getting a custom rom for this device with a great potential. I have read that having spec devices is a great start to porting a ROM from one device to another without specifically building it from the source. However it includes a few build prop tweaks and changing few lines on kernel which I have no technical expertise.
Looking forward for your thoughts.
It's true, personally I don't have this tab but I had experience with a Tab I used which was similar in specs with S4 Mini ..
You'll get bugs though and you can base device tree from the Leeco Phone to build ROMs
Anything new here?
Seems like @tuxing built a modified T813 LOS build for himself, but of course no LTE in there. https://forum.xda-developers.com/showpost.php?p=73992901&postcount=552
i really hate the lack of support for LTE Tablets :/
Hi guys, I don't know if i am on topic but 'cause of this lack of ROMs for the T819, can I install the one for the T813? I know there is no LTE, but if I wanna try the ROM can I install it or it is incompatible with the T819?

Not that easy, but I had a nice chat session with @LuK1337 and he explained me how to get things built and boot on T819: https://forum.xda-developers.com/tab-s2/general/guide-build-lineageos-15-1-t819-t3721477
It's not that difficult as I thought. @LuK1337 told me it's simple and even I managed to get it working.
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.
@emdroidle I could help
I recently came across this UBports port from @erfanoabdi that allows Ubuntu Touch to be booted as a GSI A/AB image. It requires a Halium-patched kernel though, and I don't possess the programming knowledge yet to compile a kernel and the required patches from the tree, can anybody here help with this so that we can get Ubuntu Touch running nicely on our Zuk Z2 Plus?
From what I've noticed on this forum, it seems that progress on getting this device to boot Ubuntu Touch has been helmed by @S.8506.A so I'd guess that this person already has a Halium-patched kernel they could share here. Honestly, it'd be a great win for the power-user folks among us to be able to boot Ubuntu Touch, run Android apps with Anbox when required, and even run desktop apps (so-so) with Libertine containers. Not to mention the privacy capabilities that come with booting Linux.
P.S. There's already this [Treble][GSI] Ubuntu touch for Oneplus 3/3T, note the very similar hardware (esp. identical chipset) between the op3t and z2_plus
