For the record.

Finally, after lots of testing I ended up installing another custom rom (Android 11). It passed 100% Safetynet!!!! , but had again problem with bluetooth. This time I was able to connect my smart watch but not to any audio device (car, speaker,....). It connects, disconnects all the time.

The solution for me was this, basically Toggle off the "Disable Bluetooth A2DP hardware offload" option under Developer options.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] javiercuellar73:
As fas a I know, you can't install custom rom to a snapdragon US version (I have the asian version).

My battery also doesn't last all full day, but that is normal if you haven't replace it... 2-3 years is the expected livetime. Probable you should just replace tha battery.

Hi I got S9 Plus basically this is scv39 a Japanese model 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?

Edit: I tried this rom, but it stuck at LineageOS logo, never booted up.

Hi

Hi.

I also have S9+ asian version.

You can try this (skip the CR-Droid part).

I finish installing Havoc 4.1 (Android 11) GSI here (remenber to install GApps for Android 11). Let me know if everything woks. I have a bluetooth problem when connecting to a call, I can hear but the other part can't.

Hello, I followed the instructions above and after force rebooting the device only stays in the lineage boot screen, i've flashed the zip a couple of times used the twrp provided by the post and the one in the official twrp site and i still cant get past the boot screen. I'm not sure of what im doing wrong my model is the sm-g9650 latin smerica.

[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
The instructions are very clear of which twrp to use as well as any instruction you need to follow in order to have a successful boot. All of my personal testing is done on g9650 so you guys definitely won't have any issue if you follow the instructions.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] julian.wang:
Thank for your amazing job! I tried to flash this rom on my G9600 device following the instructions. But I also got stuck in the boot logo animation. What I did:

1. install TWRP with SAR support

2. flash klabit kernel

3. flash this rom, gapps, and magisk

4. force reboot my device.

I got stuck in the boot logo.

Then I tried to flash the official twrp. Curiously, I can boot normally. But after a day of use, I find the system will kill all backgroup apps. :crying: I don't know why. And the power consumption is larger than the sumsang original rom.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
The fact that it's booted after you flashed official to twrp is coincidence. Official twrp does not support Android 10 yet.

Battery life has been better for myself and testers so I don't know what to tell you.

My instructions work perfectly fine I'm not sure why do many decide to make up their own lol
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] julian.wang:
Thanks for you reply. Does reflash the rom following your instructions work for me? Does the kernel I flashed have any adverse effect？
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] manuel.fontan:
Finaly got it to work, i followed the instructions on the original post but before i flashed the ROM i flashed 2 zips the OP has in his thread about official twrp for the sm-g9650 the files are the ones labled force encrypt_remover and multidisabler_samsung, sorry i can't post links yet but all I did to find the files was click on the op and look at his uploads. Hope this helps you the ROM is really good and worth a try.

If you guys want ota via the lineage updater just add this line to your/system/build.prop

For s9:

lineage.updater.uri=https://raw.githubusercontent.com/klabit87/OTA/master/starqltechn.json

For s9+:

lineage.updater.uri=https://raw.githubusercontent.com/klabit87/OTA/master/star2qltechn.json

In my tests, ota zip didn't want to auto install in twrp for some reason. Maybe that can resolve later but it's easy to navigate to /data/lineageos_updater and install the rom zip. My searches indicate it's a common issue sometimes?

This will be included in future builds. This is for those that want to get ahead.

I plan to upload an update/ota tomorrow.

You need to update on stock 10 First :)
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] jorgerf:
Thank you! I have a few questions, if it´s no bother.

1- Do I just have to flash stock 10.0 with odin?

2- Do I have to re-unclock my bootloader after updating to 10.0?

I really don´t know much about ROM´s on the S9+. I haven´t touched any samsung device since like 2014
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] ckbhawsar:
1 - Yes you have to flash stock 10 by odin

2- Bootloader once unlocked will always remain unlocked. But however it can give RMM issue

I recommend you to join telegram group mentioned in op if u face the issue while flashing twrp after u updated to android 10 stock:)

Edit: Calling was broken using default network settings with vzw tracfone sim.

I have the US version of the SM-G960u1. The one that doesn't have a way to unlock the bootloader. I paid the fee to have mine unlocked and wanted to install this ROM. Unfortuneatly it fails to flash with the message that it is a starqlte and not a starqltechn. For anyone else that wants to try this, the good news is that there is a workaround. Find the updater-script file in the zip and replace all of the text starqltechn with starqlte. You can use 7zip to edit it. I'm up and working with gapps and magisk both installed.

I assume once you upgrade to 10.0 that you can't roll back to 9.0?

You mean that after I've installed the ROM, on my first boot I'll be stuck on a bootloop. And then, I just have to hold Vol Down + Power Button for 7 seconds to force a reboot, and in the second boot, LineageOS should boot normally.

Is that correct?

Because I did that, but I'm still stuck on a bootloop. (In fact, I'm not stuck on a bootloop. Just the LineageOS "loading" logo won't ever end. How long should I wait?)

- Make sure TWRP with SAR support has been installed and functional.

- Download the latest build (and optionally gapps).

- Reboot to recovery

- Wipe system, data, and cache (required if you switch from other ROMs)

- Flash the latest build, gapps, and magisk.

My main concern in flashing to Android 10 is the OEM unlock.

When I first got my G9650 I kept having issues with getting it unlocked. I would enable OEM unlock in the settings and then wait the required 7 days and it still kept giving me issues with RMM or whatever.

I just don't want to screw up and end up with issues again.

Any further, step by step, details would be great to avoid this issue again.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] TheMadScientist:
The instructions show how to not get in rmm lock. After you flash twrp you need to immediately boot to twrp and flash the disabler. if you boot to system after twrp flash that's where rmm comes in

Verizon.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
It will only affect volte/hdvoice. But for some on Verizon, they can't send or receive some sms/MMS. I tested everything on Verizon and I can actually send and receive both sms and MMS. The only thing that affects me is the volte. When placing a call, my phone drops to 1xrtt but then goes back to 4g after I hang up. From what we can tell, it's a geographical thing since Verizon is actively switching some areas to 4g only versus others still have 3g on their towers. You'd really just need to try yourself to see if the functions work properly for you. Out of 3 Verizon testers, I was the only one with everything working as it should minus the volte.

As for when it could be working, I am not sure at all. With Verizon making changes at the same time, it would almost be pointless to try much until the 3g network shutdown is complete.
