LineageOS : how to ? - Samsung Galaxy S21 Questions

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:
Download Android 12 Beta 3.1 GSI (Generic System Image)
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
www.getdroidtips.com
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
15 Best Custom ROMs for Android You Can Install
Looking for the best Android custom ROMs based on Android 10, 11, 12, or 13? Here are 15 best custom ROMs for Android you can use in 2023.
beebom.com
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).

Project treble ROMs

So, am I correct in believing that almost all treble ROMs will boot on the H9, if so, there is an entire forum dedicated to project treble development on XDA, the H9 is listed as supported for at least AOSP 8.1.
Anyone think that other ROMs will work?
Link to forum: https://forum.xda-developers.com/project-treble/trebleenabled-device-development
I'm not sure if I want to risk bricking my device, it's too much effort to unbrick it etc...
Yes. I flashed LineageOS and AOSP, both are working fine. Due to us not having a properly working TWRP for Android 8.1 I couldn't install any Gapps manually meaning you can only use a bare custom rom without Gapps or Roms with pre-installed Gapps (like the AOSP Rom in your shared forum).
Have you tried the Pixel one?

Hello, has anyone (using a Treble Rom) ever had a successful SafetyNet test?

how many builds of Android Pie are out for the OPX?

How many builds of pir are there? can't any of them be installed permanently or are they all still alpha that will need reinstalled after official launch? i want to upgrade from the original OPX android to to pie for daily use. i also want magisks if that's not all supper outdated now too.
LOS 16 is really stable IMO and the dev announced it xill be the one supported in top priority.
There is no evidence that there will be "official" custom Rom on pie for OPX.
so the custom pie roms will not get updates from google?

?? I don't understand your question.
Google doesn't do anything about custom roms.
There is just one dev that worked on some custom roms on Pie (Pixel experience, AOSP and LOS). He just tond that he will put the priority on the LOS one. Note that it's marked as LOS 16 unofficial as he builds it itself, not in the LOS offcial roaster.
Onyx won't even be in the 15.1 roaster as it has just been ejected from official 14.1 roaster.

when Debian gets updates so does ubuntu and kubuntu and lubuntu and xubuntu. custom rom or not it IS still google android pie, so when vulnerability is found a update is pushed out for pie and all pie devices get said fix. unless phones don't work this way which would suck and mean it's un secure the custom rom dev gets boared or no longer has time.

You are confused, android builds are device specific, every patch needs to be integrated and compiled by the developer or mantainer of the rom you're using and can't be used in any other phone. Google releasses a new version of android and it's up to developers to create drivers and kernel "stuff" that allows the software to funcion in the device.

What about Redmi k30 Ultra Custom roms?

I was planning to buy this amazing device but i'm a little bit worried about the long term usage(atleast 2years) because of MIUI and Deminsity 1000+ .. so is there any chance of getting custom roms and gcam stable port? Because Redmi Note 8Pro is also on mediatek chipset but it has a lot of gcam port and custom rom support.
This is a phone made for China, I don't think there will be alot of custom roms. And I don't think there will be a gcam as well.
A Custom ROM basically doesn't depend on Android device's chipset.
The general approach to finding one is Googling for "YOUR_PHONE_MODEL ROM" or something similar, optionally including the wanted Android version. Try it out - you'll find what you want.

Very happy to see this and will be following eagerly @vandieutot . I really like my phone but the software is a big let down. Too many issues and workarounds required to get it working properly.
In preparation for this, could you tell me what will be required?
I currently have the K30 Ultra but its still standard phone. No root or anything else as yet.
Cheers. S'n'D

Hi,
Planning to get this phone too... But no french language is kind of a draw back.
I do not build anymore (no time) but I can offer a build server in case you need something to build rather fast.
If you need it, send me a PM.

If your rom safe to flash(no brick) im ready to help in testing.
If you can make a custom rom, that would be wonderful. Many k30u owners in China want it. There is a guy that made an Aosp rom for it, but he can't fix the bugs(fingerprint bluetooth)so if you can just help us, that would be great!

How to install custom on Android if the hardware is not present on custom rom device list?

Hey, I want to install Pixel Experience custom rom on my Android Phone but unfortunately my phone vendor is not present on devices tab. In this case what should I do? How can I install custom rom on my Android phone?
My Phone is Techno Spark 6 GO.
you could try GSI but that device shipped Android (Go edition) usually for low ram. bootloader is unlockable?
Wnat is GSI? Generic System Image? Even if I am able to unlocked bootloader on my device then what then? Since I am not able to find custom OS for it.
