Sir how did you make device tree vendor and kernel...
Sorry for asking i want to build my own ...
I tried a lot read and read and tried a lot with no succes...


Tbanks sir
If possible just give me some idea.

This ROM/OS is currently using stock vendor which means that the .zip is only containing SYSTEM and there is no VENDOR files to be flashed. That's why there is no vendor tree released nor pasted in the post. Then why we didn't use and inherit vendor files? Well its because we are facing bootloops and errors. We are still investigating and fixing the problem. How about the kernel? Well you can look on first OP post, there is Kernel Source link attached on it, feel free to use it and compile it and fork and modify it! Well I can't teach you how to compile and build some custom ROM/OS. Me too is studying them a lot of time how to build and compile ROM/OS. I took few months to understand how it is done. I also did not make the tree, the tree I got is ported & copied from LineageOS tree, and modified by my team. What ROM/OS you gonna make and compile though?

Also there is tons of guides you can find it on the xda devs forum and threads, Goolge forums and some communities that provide guides and steps to make your own ROM/OS. I can't give a guide and steps here becuase it will take long messages and steps that are not intended to be here.

    Installation.png

    1.) Use & Flash Lineage Recovery made by faizauthar12
    2.) Factory reset "DATA" ONLY!
    3.) Flash Havoc0S using ADB Sideload. Flash stock17n_kernel.zip made by faizauthar12
    Notes: You should flash stock17n_kernel to fix audio problem or else you will end up with no audio and no audio drivers. Look for Lineage OS thread for download of stock kernel
    4.) Flash GAPPS and any other things you want using ADB Sideload
    5.) Reboot System! & Profit?

    Q&A

    Why I need to flash and use stock kernel?
    Stock kernel have a working audio and working audio drivers, since the Kernel Source Code released
    by Samsung Open Source have Audio (techpack) problem or broken (according to faizauthar12).
    I can confirmed it too. This is currently better Source Code than Galaxy A80 which is totally broken and can't be use.


    When support for OneUI 2.1?
    When Samsung will release the next Kernel Source Code, then it will be out sooner!
