Hello everyone!
I've got this tablet, and I'm wondering how LineageOS and Resurrection Remix (based on Lineage, I know) custom ROMs were compiled as not only moderators didn't provide screenshots but also source code they used to make flashable zip files, and it's not even clear what works and what not works. Back in a day I also compiled ROMs for other tablet but I left source code on Github in case somebody would want to give their time and effort to make it better or find answers for their questions.
Seriously, how would I risk flashing my own tablet if I can't even see what was done to make those flashable zips, and I don't even see screenshots? Why would I take a "leap of faith" and believe that everything is working there (or works at all)?
The only real problem with this device is bloat and not having root to tweak "hosts" file.
I'll also appreciate if you tell what ROM you use and what works/not works for you.
Thanks!
the wiki is pretty much straightforward

Thanks for the link! Where can I find list of bugs or is it really works as good as stock ROM on this device?
as it is no longer maintained, you build it your own, you test it your own, you write list of bugs your own.
you can however look for the support thread.
[ROM][7.1.2][v521][OFFICIAL] LineageOS 14.1 LG G-Pad X 8.0 v521[Nightly]
LineageOS is a free, community built, aftermarket firmware distribution of android, which is designed to increase performance and reliability over stock android for your device. All the source code for Lineage OS is available in the Lineage OS...

Hello!
I'd like to build my own rom from AOSP 8.0 official branch. I'm looking for some kind of guide but couldn't find any So, let's say I've got android source code and files from other custom rom that makes camera work. What have I to do to make my rom now? How can I build it and be sure that everything will work. Generally my target is to install android 8 on my Leeco le 2 x620 device with Mediatek chip
Any help is appreciated ^v^

"I'd like to build my own rom from AOSP"
So you mean an aftermarket os like lineageos or carbonrom or do you mean that you take the aosp repo and compile aosp for your device? You can look in source.android.com
"source code and files from other custom rom that makes camera work"
Is that an already compiled rom? Because you won't get source code out of that
"How can I build it and be sure that everything will work"
Ya don't. Nothing can ever be 100% bugfree, it can either be from your device tree's source code, or the aosp code itself.
Generally, if there is a caf tree for your device, it's going to be 3x as hard to create an aosp tree.
It is going to be 100000x as hard to create an aosp tree that is for a newly released, new hardware requirement operating system.
Wanna know the topping of the cake? Mediatek is notorious when it comes to releasing the source (in fact, it has become a meme in the Mediatek users world) but don't let that stop you son.
You can try, but don't give up just because it won't compile the first couple of hundred times. The errors when compiling should give you a great start
Good luck.

Oh God, how am I meant to do this ;0 There is Lineage 14.1 project on my device. I really want to have android 8 on my phone. Thank you for all the advice.
Yes im trying the same andere without any succes so far.
Im also trying to port from a different device ROM to the stock ROM what im running now.
The chip sets are the same but the Android versions not.
It would be really Nice if some mtk ROM developer find some time in his busy life to create a ROM for our phone.
Or a guide to compile/port Android o tot oud phone.
Hey there devs.
I'm looking forward to build a pure aosp rom based on oreo 8.1 for mido.
So far I've tried and successfully built los 14.1 and rr 5.8.5 from source, but I want to build aosp source so as to create a vanilla aosp rom. I've looked on the internet and asked a couple of devs here in the forum and they told me to merge caf patches. I totally understand the point of caf but then i don't know how to do it. Also I'm pretty sure that some patches (caf maybe) need to be added to source since the compilation always gives an error related to board config, when i followed the official guide at android website. (But then I don't understand what overlays i have to apply or even what they are)
Edit : i use gcloud to build.
If anyone can guide me as to how i can build aosp, it would be really helpful:fingers-crossed:
But then any help is appreciated.:good:
Thanks in advance!
i've no knowledge on building rom but im waiting for your vanilla for sure, hopefully you made it from Note 4X as base since all 8.1 rom i have tried are giving me various app are stopping after using it for sometime. i hope i can help you in some way though i have limitation in helping. thank you for your spirit!

Don't worry man, I'll find out some way to build it. I'm Waiting for los 15.1 to get official so that the kernel source and other sources are out which i can use. But still I'm trying to learn and build.:laugh:
As there is no interest nor popularity on this device to stimulate a healthy developer community, I have decided to look into ROM building and what is required. I have followed this three part video in explaining how to build Lineage OS from source to a device. I have made it to part two where I download the Lineage OS source code to my Linux work-space. Where I get stuck is adding the source to the ROM. The question now is How do I attach the Lineage OS source code to the kernel source code for this device?
Information sources...

Current Kernel source code from Asus https://www.asus.com/ca-en/Phone/ZenFone-4-ZE554KL/HelpDesk_Download/
Just ordered one. I've never built Lineage OS either, but maybe we can work together to figure it out.
I have the lineage OS sorce code ready to compile on my system. I just need to know how to add the nesary kernel with it. Any ideas?
Any progress?

I also looked into building Lineage, seems like it's going to be more than I'm willing to commit to, so I'll share what I found in hopes that it will help you or anyone else move forward with this.
I found this restored CM wiki page on the subject: fat-tire.github.io/porting-intro.html (Sorry, can't make it clickable since I'm new)
The gist seems to be that you need to make three directories in the lineage source (note z01kd appears to be the codename for the Zenfone 4 based on the build.prop file I pulled from my phone)
device/asus/z01kd - Device file tree
kernel/asus/z01kd - Kernel
vendor/asus/z01kd - Proprietary blobs
In the above CM guide, it says to use ./build/tools/device/mkvendor.sh to generate the Device file tree from a boot.img file extracted from an update.zip (from Asus) or extracted from the phone, but that didn't work with the version I was trying to do (15.1), mkvendor.sh wasn't there at all. So I explored option #2 which was to fork an existing device file tree repo from a similar device and tweak it for the device you want to port and I found that the Zenfone Max Pro M1 (X00TD) (github.com/LineageOS/android_device_asus_X00TD) is the closest lineage supported device that we could copy from (at least that I could find). It looks like you might even be able to use the same kernel as that device (github.com/LineageOS/android_kernel_asus_sdm660) because the SOCs are pretty close (Snapdragon 630 vs Snapdragon 636), but you may need to use the stock kernel that you linked to in your original post, not sure.
There's a part in the lineage docs about building from source (only for supported devices) (wiki.lineageos.org/devices/X00TD/build#extract-proprietary-blobs) about extracting proprietary blobs (wiki.lineageos.org/extracting_blobs_from_zips.html) for the vendor/asus/z01kd folder. It said that you could use a lineage update.zip, but I was able to do it with the Asus update.zip. Don't know if that will work or not, but it seems like the only option since the Zenfone 4 doesn't have a lineage update.zip to pull proprietary blobs from.
And that's about as far as I got
Once you have those three folders set up and properly configured you should in theory be able to build it.
Update 9/3/2018
I just found the device file tree and kernel for Zenfone 4 that @shakalaca used to build TWRP. Looks like there are some different naming conventions from what lineage would expect (omni_Z01K.mk vs lineage.mk), but a lot of the stuff looks to be the same (eg BoardConfig.mk) and the files that do have a different name look like they're roughly equivalent.
github.com/TeamWin/android_device_asus_Z01K - Zenfone 4 TWRP device file tree
github.com/shakalaca/android_kernel_asus_ze554kl - Zenfone 4 TWRP kernel
Between these and the above X00TD device file tree and kernel links, we should be able to get pretty close to a working config.
What if you compile what you have and see if it boots on your device?

Sorry...I already deleted the environment I had set up, to reclaim the 50+ GB of disk space.
If it's any consolation, I never made it far enough for it to build successfully.
I am trying to build Lineage OS too
In this guide(https://forum.xda-developers.com/chef-central/android/guide-android-rom-development-t2814763)
It says we need three files(device tree,kernel,vendor) to build it.
We have kernel and device tree from github(https://github.com/TeamWin/android_device_asus_Z01K)
but we still need vendor from our device,and the commend under this guide(https://www.isthnew.com/archives/build-lineageos.html) says that we can get vendor files by running "extract-files.sh".
But where can we find that?
(Sorry for my bad English
rol.
try to look here.https://forum.xda-developers.com/pr.../tool-capire-le-treble-terble-vendor-t3774629
I have tried that CLT project,but it didn't work
Maybe use this?

Sorry for the Thread Looks, as I am not able to find any XDA template, and also a noob at making threads ;_;
1. Is this official or unofficial?
2. It's better to put the fact that it is for arm64 only in the thread somewhere, just to avoid confusion.
Great ROM, thanks for porting it to treble GSI.

Love it, I'm currently on havoc right now on my p20 pro and I'm definitely going to give this a try today. I've searched a bit but seems there isn't much info (at least from my searching) on how to handle the notch but I'll keep digging and if I find it I'll be sure to post results!
Thanks for the great work
Cant make it boot on v30 joan
it cant boot on moto g6 plus, stuck boot animation
OP, are you combining both A-only and ab in one file? If so, please name your files as such. It's a bit confusing
Anyone with OP6 running this GSI? Im unable to get it too boot...
*edit*
It stays on the "Android" Animation and it stays there, wont boot. And I fastboot flashed....
Although some users reported that could use Treble LOS 15.1 in Motorola Z2 Force, I've followed the rules to flash CarbonROM and got a bootloop into TWRP (both wiping or formatting data). I'll post later if I can manage it. If anybody has a hint to get it working, please, post. Thanks.
how i would be go for flashing ? just flash img without wipping ?
can i treblize my phone with new method and TWRP by galactic stryder, and for vendor partiotion, may i use, vendor rom revengeos_treble_vendor_x2_12082018 and for ROM may i use carbon rom gsi, currently i am on carbon rom by chityanj
can i asking... where is the download link for 04.09.2018 build?

That's just the official change log..
I would like to develop a custom ROM for my device. I read some guides and obtained some basic knowledge, but still don't know how to start. So I would like to ask some questions to test my knowledge and expand them.
My device: Wiko View
My Android version (actually installed): 7.1.2 almost pure Android (just some third-party apps)
Desired Android version: AOSP 9.0 (maybe?)
So as far as I know I need these things:
AOSP Source Code (9.0)
Kernel
Vendor (tree or blobs?)
Device tree
So for the AOSP: I can get it from the repo hosted by Google. How should it look once downloaded?
For the kernel: should I use that from my actual ROM, or the most recent one? And how to include it in my ROM before compiling?
For the Vendor: As far as I read, with project treble I shouldn't edit this. But since I'm not developing a treble ROM, I'm in troubles, right? In older ROMs (before Oreo and Treble), they're stored in /system/vendor. Is just that folder or are there more? Do I need to update something? Where do I need to put this folder?
For the device tree: I read some guides that explains how to extract it from ROM (only from 5.0 and up, since mine is 7.1 no problems, I hope). Is this right or are there other ways? Or do I need to write it myself?
I'm going to thanks anyone in advance. I know there are plenty of questions, but I hope this thread will be a place for begginer (like me) to know more about compiling from source a ROM. Have a great day!
