[ROM] [S9/S9+] [UNOFFICIAL] [LineageOS 18.1] [Exynos] [Weekly]
- Thread starter Neurotical
- Start date
In a few weeks when 3g is shut down, all these phones on Lineage will stop taking phone calls. Because Lineage cant do Volte. So only stock ROM 4g and 5g phones will be working in a matter of weeks. So all these 4g Lineage threads are obsolete. Lets all start Lineage TV threads instead. Maybe even lineage car stereo threads too. Both are buggy bloated spyware infestations.
Thank you for the info. I hope the Lineage team finds a way to enable VoLTE soon. In the meantime, perhaps those in affected areas should practice running stock ROM on the S9/S9+.

Hah. 2G is being shut down too. Only 4G is being kept as a backup to 5g. The shutdown thing is accelerating now that Sprint was gobbled up. They need the bandwidth to flesh out 5g as its usage skyrockets. I doubt that teams ever figure out Volte. Its not public access code and they got no way to see how OEMs do it.
I had read ones that VoLTE is not an international standard, so 2G is still needed for roaming. So I hope they will not shutdown 2G yet? I planed to use this rom for a while
Yea in the USA the low Gs are being shut down now. I keep getting messages from my MVNO to get another phone NOW. Shutoff of calling is imminent. I hear they will still connect to the internet though. But thats pretty useless without a calling connection. Voip apps have been more trouble than they are worth. I just landed a snapdragon s10plus for $135. I am playing with it to set it up and it really blows away my s5 in performance. Volte will be around for many years so I will get great use out of my new old phone as 5g phones come down in price. I will miss LOS though. I hate haveing all that bloatware to wade thru. Maybe Ill use a custom launcher that will hide the crap. The phone seems fast enough not to be bogged down by it.I had read ones that VoLTE is not an international standard, so 2G is still needed for roaming. So I hope they will not shutdown 2G yet?

Hi Blatu, you may be missing the roomservice part, AFAIR it is not in the official guide.
You can try my (semi-) script in post209 in this thread. Works fine using Geoknyda's git for roomservice XML.

Hi, I am very new to the custom ROM scene and unfortunately, I am quite confused. Currently, I am trying to install TWRP and it does not seem to be working? I have installed Odin, and unlocked the bootloader but when I try to install TWRP it always says "only official binaries are allowed to be flashed", could anyone help getting past this?
I believe I am, I downloaded it from that link?
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?
You need to enable OEM unlock in settings and USB Debugging from stock OS. And then try again flashing TRWP for your device (star2lte for S9+ or starlte for S9). Always verify any binary, rom, recovery etc. it should belong to your phone model.

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).

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 community12Good day everyone!
I have returned from a small vacation and time off caring for my newborn baby! He is healthy and well.
I apologize for the brief hiatus, but I am back to continue providing updated kernels, security patches, and Lineage OS 18.1 for you all!

Kernel: 4.9.290 -> 4.9.297

Now available via OTA or OP, as usual

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+8
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
- 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.
- 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
- 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;
