[Samsung Galaxy A50 Guides, News, & Discussion] JuanTamqd21:
Hi and welcome to this thread. Most A50 users really wants custom roms based in AOSP but sadly, we can only find One UI based roms here. Here is the solution. GSIs. How do they work? All android devices shipped with android 9 and above should/can boot specially made AOSP so that they can ship with google apps and phhusson and other developers found a somewhat similar aosp build and used it to build what the so called GSI roms. Now because our device shipped with android 9, it should boot aosp. But there are some caveats. Bluetooth calling, hotspot, nfc and others are just some of them. But luckily, individual developers strives hard to patch this caveats and support more devices.

How to install GSIs:

Make sure you are in either one ui 2/2.1/2.5/3.1(I suggest one ui 2.x because you can ise android 10 and 11 based GSIs while One ui 3 users canm only use android 11 GSIs)

All GSIs you will download from the internet will either come from .zip, .xz and .img. We need the latter one. If you have other than .img, just extract it.

Flash twrp for your device

Go to INSTALL

Press Flash image in lower right

Find the .img file

Flash as SYSTEM FILE

reboot to recovery(if you want root)

If you want gapps just go back to recovery and flash your gapps(opengapps ,mindthegapps, etc)

For the list of tested GSIs for a50, here they are(most of them are found in [https://xdaforums.com/f/treble-enabled-device-development-a-ab-roms.7260/] [https://github.com/phhusson/treble_...c-System-Image-(GSI)-list#official-android-11] and [https://www.recovery-mode.com/tag/gsi-rom-for-a50] I suggest you visit the forum and gsi there)

This is Lineage OS

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.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS GitHub repo. And if you would like to contribute to LineageOS, please visit Gerrit Code Review.
