LineageOS : how to ?

[Iutech]

Hi everybody.
I was given a professionnal Galaxy S21 phone.
On the LineageOS wiki i can't find this device.
I also looked at /e/ but for no better results.
Is there still a way to have a free OS on this phone ?

How do you mean free OS? do you just mean a custom rom that's free? Then I could help.

And if you mean that you can just install GSI roms on your phone because your phone supports project treble

Here's a android 12 beta GSI ROM:

Finally, the Android 12 Beta 3.1 goes live for the eligible Pixel devices after the release of beta 3 on the Google I/O 2021 Developer Conference event in

1 thing YOU DON'T INSTALL IT LIKE A CUSTOM ROM! OTHERWISE IT ISN'T GOING TO WORK OR YOU WILL BRICK YOUR DEVICE
YOU NEED TO KNOW HOW TO INSTALL A GSI ROM BECAUSE IT'S A GSI ROM
And then it's perfectly okay

I don't know if your kernel is in here
Here's also a nice custom rom where you can customize almost everything


The different maps are for the different kernels so click on your kernel

You install this just like a normal custom rom

You could find many more custom roms but these were just the biggest custom roms that are supported for your device

if you want to find other ones you could maybe look around on this website

Looking for the best Android custom ROMs based on Android 10, 11, or 12? Here are 15 best custom ROMs for Android you can use in 2021.

But you could also just search "Best custom roms" or "Best GSI roms" on google
and check if they are supported with your device (Gsi ROMS are always supported because you have project treble)

I hope this helped you!

Thanks.
I'm not sure that I understand everything though...

Free as in Free Software, so I was mostly thinking of LineageOS (since I guess Replicant isn't an option on this model), but I'm open to other propositions (as long as there's no proprietary code in them of course).
