It's the game's anti-cheat, try hiding magisk. If that doesn't work try disabling magisk for the COD app. If that doesn't work either then you are out of luck.

Does anyone help me :(
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] lewmur:
Are you sure it's not enabled already? Typically, if it is greyed out, it is because it is already enabled. But, in any case, all the FRP lock does is require you to entered the Google Account login and password the first time you boot after a Factory Reset. If you don't know it, simply remove the Google Account prior to flashing.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] lewmur:
I just received my unlocked SM-G960u1 and I'd like to try this ROM but I'm confused about how to do it. The instructions say to boot into recovery and flash the ROM and gapps. By that, I assume you mean to boot into TWRP but after hrs of searching, everytime I try to find out how to install TWRP, I wind up in a thread that says it is only for the international S9.

edit: I tried flashing this TWRP via Odin but it fails. My stock ROM is Android 10 build ending in FUC1

Phone just updated to build FUE4

[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] ele3131:
Yes they work, overall it is a pretty solid rom, not as feature rich as stock One UI, and not even close with Good Lock, but at least is much lighter.

No problem with Magisk / SafetyNet / Google Pay

No problem with Camera (GCam 7.4 Port)

BitGapps works fine.

Also Simple Gallery and CX Explorer can easily replace Samsung alternatives.

@Nyoutaa , I assume VOLTE doesn't work on this ROM? Thanks
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] bbwarfield:
I have a Samsung S9+ (model number SM-G965W).

On the Dot OS website, in the Manufacturers list, I click on Samsung, then click on "Samsung Galaxy S9+ (star2qltechn)". I'm then taken to https://www.droidontime.com/star2qltechn, which shows "Vanilla" and "Gapps".

I just want to make sure... will these 2 files dotOS-R-v5.1.3-star2qltechn-OFFICIAL-20210810-0809.zip & dotOS-R-v5.1.3-star2qltechn-GAPPS-20210810-0859.zip work on all S9+ models, including my SM-965W, which is a snapdragon model (I beileve)?

I don't want to try to flash these 2 files only to end up with a dead phone.

Thank you.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] ele3131:
If you already have TWRP, you can make a Nandroid Backup before, so you can restore everything if something goes wrong (or simply flash stock rom again).

But Dot Os should work fine, I would recommend the version without Gapps, and then install BitGapps or MicroG or Open Gapps Pico.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] bbwarfield:
Hi Ele, thank you for your reply.

Just wanna double check. Should i get this star2qltechn version? I ask because someone in Telegram suggested getting the "GSI" version. (I guess he was pointing me Manufacturer>Android)

Edit: I don't think I have TWRP installed. Can I even install it? My particular s9 model is not rootable.

Why do you recommend getting the version without Gapps?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] ele3131:
First you will need to unlock the bootloader to install TWRP, it seems possible (paid though):

https://xdaforums.com/t/sm-g960-g965-0-u-u1-android_10_root_rmm_forceencrypt_remover_add_us_carriers_fix_safetynet_aio.4051751/page-12

Ask about your device in the above thread, I don't know enough about the procedure for your device.

About Gapps, I suggested not using it because of battery life and privacy.

I end up with the downloading screen after reboot.. Flashing goes fine. Tried different TWRP and different versions (5.1.3 and 5.0.1). Starqltechn is correct. What could be wrong?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] neves4:
Guys, I have a situation.

Just downlaoded today, unlocked Bootloader and TWRP, flashed it after multidisabler and forceencrypt, and all was fine! Working good.

But now, in the night the phone battery was empty and I tried to charge it... to no avail! Absolutely nothing happens when plugging in. Tried wireless charging also, nothing works. Some people told in an old forum post that it could be corrupted kernel.

Is anybody experiencing it? How can I proceed?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] ele3131:
I had a similar issue, let the phone charge for a while and then try booting it with holding "Volume Down + Power" sometimes.

Idk why but when phone turns of with 0% it is a little hassle to turn it on again, but it will after charging for a while with holding power and/or Volume Down + Power.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] bnsilva:
This happened to me yesterday. After a while plugged in (the charger was warm, meaning there was current passing through) I tried "Volume Down + Power" and the phone turn itself on again in "Download mode".
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] neves4:
That did the trick!! Why is this happening? Is it always going to be like this?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] ele3131:
No, only when the phone turns off due to any battery life left.

If the phone is draining too much in idle, try Naptime (Disable Motion Detection) and Better Battery Stats 2.5.341 (Monitor Wakelocks).
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] neves4:
That's terrible!! I'll have to plug it in then. I realized another weird thing: sometimes audio on Bluetooth suddenly gets muted, so I'll have to re-pair it in order for it to work.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] chikabrika:
Anyway you could possibly add support for star2qlte? Yes the US version, yes I have TWRP on it.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Pteroglossus:
I just installed this ROM on a US SM960u. Install failed because it was the wrong device, starqlte instead of starqltechn.

With some help I found out that you need to unzip the DotOS package and edit the "update-script" file located under "META-INF/com/google/android". Completely remove the "assert" line at the top, save and compress the file again. Then flash using TWRP.

I believe the same trick should work for your star2qlte.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Pteroglossus:
Same thing happened to me last night, your solution worked like a charm! Thanks!
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Pteroglossus:
I've been using the ROM for 5 days now, everything works great apart from two things:

- Battery usage is high (around 6%/h) on average, I did as @ele3131 suggested and installed naptime and betterbatterystats. The latter detected that most partial wakelocks happened because of "NfcService:mRoutingWakelock". I went and checked whether NFC is on and it turns out it's toggled on and greyed out...Any idea on how I could solve that?

- Bluetooth works great for listening to music but doesn't for calls, on three different BT devices. I read somewhere that disabling "Bluetooth A2DP hardware offload" could do the trick, but again the option is toggled on and greyed out. Any thought?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] ele3131:
Before coming to DotOS, did you update your phone to latest (One Ui 2.5) and did a clean flash of TWRP?

Here Bluetooth and NFC can be enabled, try finding them inside "Settings", if not crazy I remember seeing a similar issue with Quick Panel alone. If it does not work try cleaning cache and dalvik cache and dirty flashing the rom again.

Here I have 1,2%/h.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Pteroglossus:
Before unlocking the phone using @afaneh92's service, I was on OneUi 2.5, I followed his instructions and factory reset, so yes, I believe it was a clean flash.

The issue for NFC idoesn't only occur in the quick panel, the option is stuck on and greyed out in the settings menu.

I did not install magisk and am therefore not rooted, could that be related to the problem?

As for bluetooth, I can turn it off and on, music works but calls results in either no sound at all or the person I'm talking to saying it's really loud and garbled. Have you tried making calls using BT on your s9? Does it work?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] afaneh92:
NFC issue because of kernel based on china s9
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Pteroglossus:
OK, thanks for the tip, anyway I could flash another Kernel?

Also, is the BT problem known of you @afaneh92 ?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] afaneh92:
Currently, kernel still under development. When its ready will let you know.

I don't have the device so Im not aware of any issues with custom roms
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Pteroglossus:
Ok thanks, I'll wait for the Kernel then.

@ele3131 what S9 variant do you have? Is BT working well on your phone?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] ele3131:
S9 SM-G9600 (Klabit Kernel).

Bluetooth works fine, have been using it with my TWS earbud without problems.

always ringing when answering a phone call, what's the reason and how to fix
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Pteroglossus:
If i understand well, the reason why some features work for you and not for me is that you have an international, bootloader-unlocked version of the S9 and I have a US, formerly locked version.

I would consequently encounter the same issues using another ROM, can someone confirm?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Teet1:
I have the same issue here. I just decided to disable the NFC service and it improved battery life, but still not the best around 7%/h. it was around 10%/h before i disabled NFC

edit: don't just disable the NFCservice app, do

adb shell pm hide com.android.nfc

. this completely disables the nfc service, otherwise on reboot, android will attempt to revive the process continually and will make the battery and heat issue worse. speaking from experience lol. this is the only way to have normal battery life on this rom for most of us until the issue is fixed, so NFC doesnt work anyway. Might as well improve battery life and heat
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Pteroglossus:
Thanks for your reply.

To be honest, between the high battery drain and bluetooth call not working, I'm thinking of changing ROM. I just sent a post on Jkruse's thread to see if I should transition to his ROM.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Teet1:
After a day of using my phone after disabling the NFC service completely, I have impeccable battery life. See attachment. I have excellent idle and with the help of Naptime my phone can deep doze. Heat is also not an issue anymore. It's even better than stock. Of course, it doesn't have the features of stock. But the customizable features is what sells me. Give it a try. Do the adb command and reboot and you'll see a difference. I haven't tried Bluetooth call yet though. Maybe there's a magisk module that could fix it. I haven't looked
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Pteroglossus:
Ok, I gave your suggestion a try and haven't been able to deactivate NFC:

k*:~$ adb devices

List of devices attached

4******************** device

k*:~$ adb shell pm hide com.android.nfc

Exception occurred while executing 'hide':

java.lang.SecurityException: Neither user 2000 nor current process has android.permission.MANAGE_USERS.

I'm not familiar with Magisk and haven't installed it, I'm guessing I'm not root and I do not have the proper permissions?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Teet1:
You need to run it with root. I forgot to add that so apologies. You'll need magisk or another kind of root method.

Do

adb shell su pm hide com.android.nfc
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Pteroglossus:
I've found various methods to install Magisk, including the official way that implies flashing the latest firmware, which I know may re-lock the bootloader.

Could you point me to the install method you used so that I'm sure I won't mess anything up?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Teet1:
Do you already have twrp? I assume you do if you have this rom. All you need to do is find the latest magisk zip file and flash it. Open the magisk manager app after you reboot and it'll update the app. That's it. You'll have root. You'll need to do some extra steps to pass safetynet if you want that.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] kdm6389:
my device name is Samsung Galaxy S9 G960U

Model number: SM-G960

Device name at adb is: starqlteue

My question can I install this ROM ?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Pteroglossus:
Magisk installed, I was able to run the cmd to disable NFC. I did notice a decrease in battery usage at around 5% an hour but I haven't used the phone that much today.

However, at the end of the day, BBS still shows this:

Is NFC really deactivated?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Pteroglossus:
If your bootloader is unlocked I believe you can.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Teet1:
It doesnt show up anymore for me. Did you fully charge it after disabling NFC? it may just be counting the time when NFC was still active. If your phone isn't hot or warm at idle then its probably disabled lol. To be really sure, do adb shell logcat. If the window is being spammed with errors then NFC is still active although im not sure why it would still be running. Thats the command that got rid of it for me

edit: today i can confirm that bluetooth calls indeed do not work. I hope that a kernel can be developed that fixes this issue and NFC
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Pteroglossus:
Below is a short extract from the continuous flow of errors after I run the "adb shell logcat" command:

10-11 10:02:25.522 20457 20478 D NfcService: NFC is on. Doing normal stuff
10-11 10:02:25.522 20457 20478 I NfcService: Enabling NFC
10-11 10:02:25.528 20457 20481 E libnfc_nci: [ERROR:gki_ulinux.cc(98)] gki_task task_id=0 terminating

I've tried revoking the "shell' permission on Magisk and running the "pm hide nfc..." command again. I'm asked to grant permission, which I do of course, and the terminal hangs there indefinitely. I've tried rebooting also.

Any idea?

Edit: I tried again entering the shell first, then su, then "pm hide com.android.nfc" and rebooted. It seems it did the trick! No mention of NFC in partial wakelocks in BBS and no NFC-related errors in logcat.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Teet1:
Great. You should see a significant difference in heat and battery usage :P
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Digital Dragon:
Is mirrorlink included in this ROM?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] yang2828521:
Let me test it
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Pteroglossus:
It's been a couple weeks now and the improvement is significant. The battery lasts a day and a half in normal use. The average battery drain is about 2%/h according to BBS. So thanks again for the help.

The only thing that bothers me is the inability to use blutetooth for calls. I'm not going to ask for ETA on Kernel development as it's quite frowned upon...i'll just wait and use corded headset then!
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Teet1:
I agree. I'm also having issued with the galaxy wearable app disconnecting my watch when something intensive happens like opening gmail or playing YouTube. Sometimes it even just closes YouTube if I open gmail. It's annoying. I did a factory reset and it helped for a day but now it's going it again so I'm not sure if it's the Samsung apps running with magisk hide, or the rom itself

A young whippersnapper refers to quick witted smartassery in younger person percieved to belittle the elderly when their culture clashes in communication. He understands you. But know you have dismissed him. Now he either dons your title for him "old lad" in symbolic prostration through conplacence or denies your dimimishment of him through a ritual separation demonstrating dissappointment in you, facilitating disassociation from you.

You symbolicly hazed a village elder out of town.

Human roles never change, but they rotate face so fast it fools the actors. Nothing new here.

Carryon primates. These instincts are part of what humans are.

They must express themselves. We can only try to redirect them to some extent and mask them with social abstractions. Until some great mutation propagation rolls lucky for change in that department. Such processes of change are so slow as to be virtually timeless from social scale perspective.

##edit#

No disrespect to any is intended. To my knowledge, humans are in deed highly specialized primates, even if not in their own perspective.
