Hi im wondering if it's possible to build android 9 for a device that shipped with android 10 and has no support for android 9. I'm using a Google Pixel 4, running an Android 10 rom that I compiled from aosp. It's fully rooted, unlocked, twrp, custom kernel, custom rom. I'm new to building android but I've successfully built roms from lineage 17 and 18 for my pixel 4, as well as android 10 and 11 for my pixel 4. Im curious if it's possible to build android 9 for the device. And if so, how? The aosp website doesn't give much information on the process.

hi, i want to make my own rom but all tutorials are for android 5 or 6, and i want to know if are some diferences between android 8 oreo, because my target its to start from a samsung stock oreo rom
i recently rooted my phone trying to install viper4android which just wouldn't work on my android 10 stock rom no matter the workaround. so i was thinking of going for a stock rom for the first time. most threads on roms don't have many bugs listed unless you search through comments where it gets kinda confusing. so if you have any experience with custom roms on realme 3 pro, you can help a guy in need . i also included android 9 because viper4andoid is apparently easier installed on android 9 than 10.
I would say pixel experience but the dev announced that he is dropping support
Basically the title. There aren't many aosp 10 roms for my phone (J7 prime) but There are many pie roms. I would like to start creating roms for my phone. But I can only find android 9 device tree. Can I use this tree to compile android 10 roms? If not how can I somehow make it compatible, if it is possible. Any help is massively appreciated.
Hey Dear Programmers,
This Is a Humble Request Please make a custom rom based android 11 or 12 for SM-J510F(J5xnlte)
why though
the only a11 rom the j5 currently has is bliss, and that one is not even stable yet

Hi, guys! I'm new at this stuff. Can you please help me to understand where I am going wrong. I want to build Android 12 from AOSP source code for Android 12 following the instructions here https://source.android.com/setup/build/downloading and separately build the kernel from here: https://github.com/MiCode/Xiaomi_Kernel_OpenSource/tree/mojito-r-oss.
After that, via TWRP install the AOSP image first and then the kernel image. And then GApps. Will it be enough for the device to work properly, what am I missing?
