General Development of LineageOS 20 for Xiaomi 12 Pro

NeoArian · May 24, 2023

Development
I have been working on LineageOS for the Xiaomi 12 since a while and extended that work to the Xiaomi 12 Pro since the devices have huge parts in common.

All the kernel repositories can be found here: https://github.com/xiaomi-sm8450-kernel/
All the device repositories can be found here: https://github.com/cupid-development/

If you are interested in building LineageOS for Xiaomi 12 Pro yourself, you can use the following two local_manifests:

Code:

xiaomi_sm8450_kernel.xml

repopick -t 13-kernelplatform

After applying the necessary patches you will have to extract the vendor, either from stock Xiaomi 12 Pro ROM or, preferably, from my shared LineageOS 20 build which can be found below. Use the extract-files.sh script in device/xiaomi/zeus to do so.
The vendor repositories are on gitlab now and included in the manifests above.

Due to the Generic Kernel Image setup we build the kernel before starting the LineageOS build, to do that execute the following commands to prepare your environment:

Code:

. build/envsetup.sh
breakfast zeus

Now use this bash script to compile the kernel:

Code:

#!/bin/bash

export TARGET_BOARD_PLATFORM="zeus"
export OUT_DIR=${ANDROID_BUILD_TOP}/out/msm-kernel-${TARGET_BOARD_PLATFORM}

export LTO=thin

./kernel_platform/build/android/prepare_vendor.sh ${TARGET_BOARD_PLATFORM} gki

Now you're ready to start the actual build:

Code:

brunch zeus

Installation
In order to flash the compiled build you can follow the instructions from my thread for the shared builds,
Make sure you are using firmware from MIUI 14 based on Android 13 before flashing LineageOS!

I hope this can help other interested developers to get AOSP for Xiaomi 12 Pro in a better shape!

Hello and thank you for your interest in our precious xiaomi 12 pro. I would gladly test your rom when it will be relatively stable!! Congratulations for the work already done!

Danacy · May 24, 2023

Amazing! Thank you very much for sharing it here. I lack the technical knowledge to start this off but like @Maxou6440 above me here says, I also will be available for beta testing if needed.

If LineageOS goes unto my 12 Pro I think I will stick with it forever

Waiting for your ROM.Great!

Are there plans to completely finish this project or is it as-is? Anyway thank you so much for putting in the groundwork for ROM development for our phones. Can't wait to see where this all goes!

Yes, I will buy the device soon. There's is a crowdfunding running to support it, which is mentioned at the bottom of the first post.
I intend to get both, Xiaomi 12 and 12 pro, official at lineage in future. Once I get the device I should be able to get it working soon on an unofficial version

Official might take a while.

Getting official will always take a while right? Needs to get into some process, core of the LineageOS must already be of high standard, etc. I've seen the development with other devices.

I donated to your PayPal, hope it works out with the 12 Pro. Thanks again for picking this up

Kkjin · May 30, 2023

l’m very excited about the Xiaomi 12 Pro LineageOS development news.

I have a quick question: Is it possible to achieve a maximum of 480Hz in touch sampling?

Is the cn version the model you buy and develop?

If it is possible, I will definitely purchase this device.

Kkjin · May 30, 2023

i love neo!~

rpi_luver · Jun 4, 2023

OMG cant wait for this! Im super happy to become your alpha tester for this ROM

NeoArian · Jun 6, 2023

Hello everyone!

I have received my Xiaomi 12 Pro yesterday and am currently waiting until i can unlock the bootloader.
In the meantime i have tried some more things regarding the issue with the touchscreen - with success!
There are still major issues on the build, namely:
* SELinux is permissive
* UDFPS does not work
* Setting a screen lock does not work

However, if you are still intersted in playing with lineage on zeus already; you can download it here and follow the instructions from my Xiaomi 12 thread (linked at the first post in this thread): https://github.com/arian-ota/ota/releases/tag/20.0-zeus-1c07013d

There might not be many updates from me within the next week.
Have a nice day everyone!

Hello friends, is it possible, like Generic System Image (GSI), some extra settings. As shown...

Awesome, great news. After the mandatory waiting game I wish you a lot of fun with the puzzle

And of there is an usable ROM I will be available for beta testing. I use it as a daily device so need a little bit of stability, okay with bugs and stuff to discover. Thank you again!

SesshomaruSVNN · Jun 10, 2023

Waiting for fixing udfps.
Very happy because of developing the AOSP Rom. Thanks developer.

Ninenaiwa · Jun 14, 2023

hi. you use fw. version ? and gapps ? tell me please.

piyushyadav30 · Jun 15, 2023

Waowww...

Thank you so much Developers....
Now the Game Begin...
Xiaomi 12 pro have a good hardware phone.. Thnx to developer for making them. Amazing....

我一定要练会李别 · Jun 15, 2023

Thanks♪(･ω･)ﾉ

NOSS8 · Jun 15, 2023

Hi ,NeoArian
I installed the rom successfully but the touchscreen does not work so I get stuck on the LOS welcome screen.
Maybe my mistake to have installed NikGapps-core-arm64-13-20230531 since the recommended one is A12.
Even after a complete formatting and reinstallation without gapps no touch.
