Galaxy S9, S9+ & Note 9 Losing Official LineageOS Support!

Bad new as the Galaxy S9, S9+ & Note 9 are losing official support as you can read in this Lineage Gerrit Code Review Merged commit: hudson: Drop exynos 9810 devices and expand lineage-build-targets.

As you can read in the LineageOS wiki > Devices and check show discontinued devices > in Samsung Galaxy S9 (starlte), S9+ (star2lte) & Note 9 (crownlte), for example:

The old builds are automatically removed from the LineageOS servers after 4~6 weeks so you should save a copy of at least the last build & Lineage recovery if you have one of those models.

Naturally if an other volunteer developer steps up & picks up the torch new builds may become available again.

Thank you to maintainer @erfanoabdi for supporting these devices for so long & also for all his numerous other contributions in the LineageOS Gerrit as seen here.

so sad :'(

Is there another alternative?
[Samsung Galaxy S9 & S9+ Cross Device Development] rogerwilco75:
I can only second that sentiment. Such a shame. :cry:

Hopefully a good alternative will become available.

Apart from the non-removable battery it met/meets so many of my 'requirements' for a phone running a non-stock ROM.

Try disabling 802.11r on the router, and/or other settings on router. The 802.11r caused an issue for me on xperiaZ3 running lineage 17.1.
[Samsung Galaxy S9 & S9+ Cross Device Development] jomann:
Thanks for the reply. Unfortunately, I don't currently have 802.11r enabled. It's disabled by default on OpenWRT and I'm just now setting up a second AP. Is specific to LOS 17.1? This is my first Android 10+ device.

I'm having problems installing the recovery and the ROM:

[Samsung Galaxy S9 & S9+ Cross Device Development] gnarf49:
Not sure if it is the same issue: Check on your phone's screen. On my S9, when installing via ADB while in Lineage Recover, I get a Y/N choice. If no Y within n seconds it times out with error.
[Samsung Galaxy S9 & S9+ Cross Device Development] jomann:
IIRC, I got the same ERROR from heimdall when the phone was in KG "prenormal" state after unlocking. If you can get into download mode with the extra background text it will show you the KG state. I'm not sure what causes the background text to appear or not in download mode.

Also, the device may display a message indicating "permission denied" I think.

Hello

I know that we have to be carefull with this:

"MAKE SURE YOU ARE INSTALLING LINEAGE OVER FULLY STOCK ANDROID 10 FIRMWARE"

But is it possible to flash the latest Official LOS17.1 zip over latest Unofficial LOS17.1 because my s9+ is already on the Android 10 firmware?

I have already flashed the stock vendor for the Unofficial.

And why we need Heimdall while i have flashed the Unofficial with TWRP?

Would it be possible with TWRP?

The Unofficial is running nice but i wanna check which one i like the most.

Regards

I didn't find any clue about that quirk on the interwebs.

My linux PC does give me the following Info about the adapter, as well as the fact that the adapter is working fine connected to my PC I'd guess LineageOS17.1 is the cause of fault.

Master,

Hi I got S9 Plus basically this is scv39 a Japanese model, S9+ and I was able to flash this TWRP twrp-3.5.0_9-0-star2qltechn.img.tar now I can boot into TWRP but I dont know which rom I can try on it? will this work?

I tired this one but it didn't work

https://xdaforums.com/t/rom-10-0-havoc-os-3-7-for-galaxy-s9-s9-note9-unlocked-bootloader.4097909/

when I install this rom here Havoc-OS-v3.7-20200709-star2qltechn-Unofficial.zip

I can't boot up into the system, I had a bootloop after installing and forced restart it but after it restarted it went to download mode

I manage to pass the samsung boot logo but I'm only seeing white circle loading for about 45 mins.

I did these steps

1.I unlocked bootloader and installed TWRP

2.Wiped system, data, cache, dalvik

3. Installed rom, gapps, and magisk and reboot

4. It had bootloop on first boot and had to force restart

Am I missing something?
[Samsung Galaxy S9 & S9+ Cross Device Development] testerS4:
I tried it with 18.1. But I'm not happy with this version. It's not a lineage problem, but with Android 11 itself. Google is complaining too much. Many app developers are annoyed by this. They can no longer build their apps the way they want. I'm back to 17.1 for the time being. Is it possible to install the latest security patch myself?

I do not wanna setup my phone again...
[Samsung Galaxy S9 & S9+ Cross Device Development] D9yHyi8Fe3mo1YgM:
I am trying to install LineageOS 17.1 on a brand new S9 plus Duos (SM-G965F/DS, obviously Exynos). I have got the ZIP file from the link given in one of the posts above (https://mega.nz/folder/vdYx2aaD#C2yT_SeG9RYC7GMI-C3qyw).

However, when trying to install it, the installation fails, and the installer (or the recovery) says something like that this image is for starlte, but my device is star2lte (I don't remember the exact wording).

Well, it's quite obvious that my device is star2lte, but where can I get an LOS 17.1 image for that? I have read the instructions on how to compile my own image, but to be honest, I am not very motivated to set up a linux box just for trying to compile my own image, which in addition will probably first cost me days of trying to fix compiler errors or misconfigurations of that system and will then fail in the end.

Besides the question from where to get that image, the latest images seem to be nearly 6 months old now. I have used LOS on some other devices where updates came weekly or bi-weekly.

Hence the question: Has development of LOS for star2lte been abandoned? Is ArrowOS (mentioned above) the official recommended alternative? Or should I go for the (yet?) unofficial 18.1 version?

Thanks a lot in advance!

i'd probably stick with stock/modded stock on a samsung phone. if you wanna try AOSP, i just saw a new ROM come out today called derpfest (yeah, funny name), you should probably try that. seems to add several enhancements to improve user experience
[Samsung Galaxy S9 & S9+ Cross Device Development] D9yHyi8Fe3mo1YgM:
Thank you very much for your response.

I have found a solution in the meantime: ArrowOS 11 (based on Android 11). I have installed it on my phone, and I am very happy with it. Maybe some exotic functions don't work (described in the first post of the thread linked before), but I really can live without VoLTE and WiFi calls and the proprietary Samsung apps. The reward is that I now have a very nice, fast, Google-free phone which doesn't track me all the time.

I am not a heavy phone user and have installed only a few apps. In this scenario, I never have experienced a crash or other oddities, and the battery runtime is excellent. I didn't try OTA updates yet, though. One of the best things about it is that it does not hide the external SD card's contents. I can access them even with the stock file manager, as well as via SSHelper, which is ingenious and makes a very interesting backup concept possible.
[Samsung Galaxy S9 & S9+ Cross Device Development] m4f1050:
Does this have Screen Mirroring (miracast) like the stock S9+ had? Trying to mirror on my BMW car.

What about this ArrowOS 11? Does IT have miracast screen casting?

OTA update solve

Hi,

So I figure that using an official DTC5 vendor image solve the OTA update problem. So forget about the modified vendor from synt4x.93 (which provide the ability to not encrypt your phone I reckon) if you want OTA update working.

From now everything is working amazingly fine, the battery management is awesome, it's like having a new phone. Thanks to all people involve to make it happened !

So the options for the official LOS are the following?

1. Using DTC5 vendor from [MENTION=7861769]Synt4x.93[/MENTION]:

Official OTA won't work but you can use TWRP with all its functionalities since encryption isn't forced (but possible - with the same behaviour as written in 2.).

2. Using stock DTC5 vendor:

Official OTA will work but you can't use all the functionalities from TWRP since encryption is forced and TWRP can't handle that.

Hello, everyone,

Thanks for the great job, I have

then the BL DTC5

At first sight everything looked good, but the phone switches off (even after a fresh installation) as soon as I connect it to the PC and activate file transfer.

In the following case the problem occurs:

I start the phone,

Android debugging

is active in the developer settings, I connect the phone to the PC and activate file transfer on the phone.

In the following case the problem does not occur:

I start the phone, Android debugging is active in the developer settings, I connect the phone to the PC and deactivate Android debugging for a short time and then switch it on again, then activate file transfer on the phone and the phone doesn't stop working.

Can anyone confirm the problem? Or how do I fix it?

[Samsung Galaxy S9 & S9+ Cross Device Development] vincent-v:
Hi,

Thanks for your answer. I had forgotten to write that TWRP 3.3x is installed.

Unfortunately this didn't help either, same problem also with the unofficial LOS 17.1 version of Synt4x.93.

With the 17.1 I have even more problems, Magisk seems to run in the current version, also xPosed I can install and xprivacylua. But xprivacylua often brings the message that it is not activated.

Other apps like AfWall and AdAway seem to work, but I don't want to use the phone without xpricavy.

when I am faced with the choice of whether or not

1. LOS16 unofficial, with AFWall, AdAway and xprivacylua

or

2. LOS17 official, with ADWall, AdAway but WITHOUT xprivacylua

then my choice goes to option 1.

I can live with the crash when I activate MPT, the other error is too serious.

Edit: I just noticed that the xPrivacylua error message only appears if TWRP cache/Dalvik was deleted and restarted before. After a reboot without deleting the cache/Dalvik xPrivaycalua is working fine.
