Not sure then if you have unlocked the bootloader in developer option it should be fine.
I take it you put the phone into download mode before flashing?
Yup, it's in download mode already. I think it may the RRM thing? I have looked around and mine says that it is not yet authorized ( I forgot the exact phrasing).

Can you connect to the internet over wifi? if so then try to update the software over OTA, then retry, this is where my knowledge ends, if this does not work then maybe someone else can come to the rescue and help solve this annoying problem.

Hello guys!

Has development of this ROM stopped? Should we start looking for an alternative again? It was a really stable and fast one so that's a pity..

Hello I need to ask something. I have a problem with RAM on my galaxy s9 custom ROM OneUi based. Everything works fine and I like almost everything but since I use a lot of multitasking, many apps get force-closed. I ask if this Lineage ROM is noticeably better to manage RAM and has more free usable ones.
Also I want know if the camera is better or the same and which is the best alternative because I don't want lose quality and slow motion. Thanks.

Anyone know a camera app that will let me do an exposure greater than 1/10s? I've tried the default, open camera, and proshot, none of them do it

I would love to maintain it officially. In fact I reached out to the Lineage team about doing just that in September last year.

They responded back outlining how there are a lot of procedures to follow, including needing a team to manage the device tree and other repos. There were also some things that me not being a programmer just can't provide like being able to independently bug fix compile errors when changes are made by the LOS team that are incompatible with the S90/S9+. Right now I rely on the community to help with these fixes and I just copy them. It's worked so far because there are, humbly, more knowledgeable people maintaining device trees than I.

That leaves me in a position where I am learning from the experts and this wonderful community in a collaborative effort to keep the LOS 18.1 going for the S9 and S9+ :)

Oh That's Sad.Maybe You Can Try Apply To Become the official Maintainer for this phone like dot os Or Pixel Experience since There is no developers maintain it. and maybe it easier to recompile.if you really want to become the official Maintainer of lineage for this phone.why don't you reach out to them that helped you with the codes and error to compile for this ROM maybe You Can work With Them... Good Luck On Dev World.And Thank You Very Much For this ROM Hope You Can Update the security patch occasionally. 😀😀

Thanks for the interest!

I suppose the first step would be learning how to compile the Lineage 18.1 ROM using my repos in a roomservice.xml. There are lots of tutorials on how to do this. Once done, I would benefit from help learning how to add in some programs to the ROM build. I think the community can perhaps vote on which, if any, programs could be included in the ROM, like Aurora Store, F-Droid, and the like.
At first, congratulations on the new born son, I am glad to hear he is well and so are you, nice to have you back :)

I have not forgotten about the post above, and still willing to help.
But I kind of stuck, I could not figure out what you meant exactly with your repos and the "roomservice.xml". And also could you recommend a tutorial? I have a dual boot computer with Windows and Linux, so I think it would be better to try it directly on Linux. I am not sure which tutorial I should follow exactly, would be nice if you could give me a hint where to start best :)

Thanks so much! He's a happy baby and we are happy parents :)

Your question is a big one, so I'll start at the beginning and we can move on from there one step at a time.

I am only familiar with running Linux (Ubuntu) in a Windows virtual environment. The first step would be to install that using this guide: https://docs.microsoft.com/en-us/windows/wsl/install. The next step would be to build LOS using this official guide here: https://wiki.lineageos.org/devices/starlte/build.

When you get to the part about extracting proprietary blobs, you can skip that and instead use a 'roomservice.xml' file. You will see that I created a 'local_manifests' repo on my Github account that houses the xml file you'll need. Download it and place it in the ~/android/lineage/.repo/local_manifests directory of your Ubuntu system. Then you should be able to start the build.

If you have any issues, please let me know and I'll do my best to share and help :)

    Great ROM so far, very stable. Thank you for keeping this project going :)
    This update was the first time I got a error when downloading it from github and wanting to install it (zip file was corrupt). I hope redownloading does the trick.
    Is there a way to check for updates in the OTA updater and have older files available? For me it only shows the latest one.
    I hope re-downloading it fixes your issue. The only way to install older versions is through adb sideload the older ROM in recovery. Older versions can be found in the OP, or here. You can install it over your current one, no need for a format. You can keep all your data when downgrading.

    Good day,

    I just want to take a moment to say thank you to everyone who has tried this ROM, given feedback, and even helped out along the way! It is with all of your help that I can keep the builds coming and I look forward to doing this for as long as I can for the S9 and the S9+ :) Our community deserves the best and that only happens when we all work together :)

    Have a great day, and thank you again to everyone in this community :)

    A couple of questions as I am somewhat new:
    1. Why is this build unofficial resp. what is preventing this build to become official again (as starlte official was discontinued after LOS 17.1)?
    2. How trustworthy is an unofficial build compared to an official build?
    With regards to safety and trustworthiness:
    • Everything is open source so anyone can see what is going into the all the builds. This includes the kernel, Lineage OS, and Samsung device trees. These links are in the OP.
    • I don't make any changes of my own because I am not knowledgeable enough to do that, but I do copy kernel patches from the Linux Long-term Maintenance team run by Linus and Greg for the 4.9y branch; I can at least bug-test and roll them into the weekly ROM builds. Linus & Greg pretty much head up Linux entirely, so the patches they approve are as trustworthy as you can get :D
    • I also got the Wireguard kernel patch into this build, which is pretty awesome, but without the help of the contributors in the OP, I really wouldn't have been able to do it on my own.
    With regards to making it official:
    • I was using the official Lineage OS, but when the support for official status was dropped, I started learning how to build Lineage for unsupported devices. Then I came across Synt4x's repos, which gave me all the resources needed to build Lineage 18.1 for the S9 and S9+. I simply maintain kernel patches that come out weekly by the Linux Long-term Maintenance team (Linus & Greg et al.), work with the community here to maintain the device trees, and then compile the builds as often as needed.
    • After I got the hang of all this, I figured everyone who has an S9 or S9+ should be able to benefit form Lineage OS 18.1 support. These phones have great hardware and I think it a shame not to allow users the option to de-google it or take full control of it so soon after it has been released. Besides, the 4.9y kernel is going to be maintained until 2023. So I upgraded from a 3600 to a 5900x and 16gb RAM to 32gb RAM to speed up the builds (each build is only about 8 minutes now) and support the community!
    • I would like to see an official build, but I can't maintain it all by myself. I am not a programmer, and most of the code I look at is jibberish to me; I just trust the Linux team and Lineage OS team. So we need the community here to help me with build errors when the Lineage team makes changes to their OS; I'm not knowledgeable enough yet to tackle those problems on my own. But I am learning, and have successfully tackled two compile errors so far with the help of the community, and I've learned from them :D
    What you will get with this build, even though it is unofficial is:
    • Kernel updates straight from the Linux Long-term Maintenance team; this is very official and safe;
    • AOSP security patches straight from the Lineage group; this is very official and safe;
    • Lineage OS updates as they roll out; this is very official and safe;
    I literally can't do anything else because of my limited skillset.
