I highly appreciate all the support, im not sure as i haven't tested it out yet but it could be.

If you decide to test it out keep me updated with the results, have a good one.
[Samsung Galaxy S9 & S9+ Cross Device Development] RchrdWllm:
Hi! I just tried out the ROM, and it seems great so far. But I'm having problems signing in to my Samsung Account. It always says "processing failed." I tried to change my password to see if it works but it still doesn't. Any fixes? Thanks for this great ROM btw!
[Samsung Galaxy S9 & S9+ Cross Device Development] bobrom7:
Me Too! same problem. Go back to "_alexndr ROM" no problems? Wonder if it is the Kernel at fault?

Is it possible to list the "De-bloat" items that have been removed from this ROM?
[Samsung Galaxy S9 & S9+ Cross Device Development] xfirefist:
I haven't tested this out as i never sign in to my samsung account (go figure). If you find a solution let us know!

The following items were removed:

- SamsungPass (Password auto-fill service)

- SamsungPay (Does not work anyway since knox warranty is tripped)

- SecureFolder (Does not work anyway since knox warranty is tripped)

- SecurityLogAgent (Does not work anyway since knox warranty is tripped)

- Chrome

- ChromeCustomizations

- BixbyWakeup

- Gmail2

- GoogleTTS (Google's implementation of text to speech)

- KidsHome_Installer

- Maps

- Bixby

- BixbyAgentStub

- BixbyHome

- BixbyService

- SettingsBixby
[Samsung Galaxy S9 & S9+ Cross Device Development] RchrdWllm:
I tried to sign in with my Samsung Account after the setup, still failed. Tried as well with a different Samsung Account, but still failed. I can use this ROM without the Samsung Account. However, I still do want to use Bixby XD
[Samsung Galaxy S9 & S9+ Cross Device Development] Leon:
This is an issue related to root and custom roms. Alexis included some fix in his rom so people still can use Samsung account.
[Samsung Galaxy S9 & S9+ Cross Device Development] RchrdWllm:
Oh I saw that zip file. Maybe I'll try to flash that fix with this ROM sometime as I'm currently back to stock ROM.
[Samsung Galaxy S9 & S9+ Cross Device Development] RchrdWllm:
Yo guys! I can confirm that this worked for me, quite a relief XD. Sign in during the setup, and remember that you have to update the Samsung Account application through the Galaxy Store. After that, you can fully use Samsung Account. Thanks Leon!
[Samsung Galaxy S9 & S9+ Cross Device Development] bobrom7:
Just tried this method and did not work for me. I can sign in during setup but fail on sent code. Seems you cannot disable this two step verification anymore. Galaxy Store asks you to sign in again to down load, same problem, so back to _alexndr 7.3 ROM. Everything works for me on that. Would be nice to find a "FIX" for this problem.

FYI. I do de-bloat a lot of apps using opion.prop file. Not sure if it is right or wrong but works for me! e.g. see zip for my info.

08/04/2020 Update: I have installed WHITE.WOLF.ONEUI.UNI.Q.007 Kernel onto _alexndr 7.3 ROM and I am able to sign into Samsung Account plus so far (2 days) everything seems to be working.

Does this flashable on SM G965N variant?
[Samsung Galaxy S9 & S9+ Cross Device Development] xfirefist:
This rom is based on the European firmware.

The Korean variant shares the same platform with the European models (universal9810), in theory it should work however there might be a few side effects such not being able to make phone calls or connecting to mobile data.
[Samsung Galaxy S9 & S9+ Cross Device Development] YazumiWuHung:
I have Korean version, the only problem is you have to add apn manually, it's not being detected. The rest is working 100%.

is the magisk Include ? My TB doesnt work
[Samsung Galaxy S9 & S9+ Cross Device Development] get2easy:
So now it's done. I have the firmware DTC5 r5 flashed. reboot and it's done. You want to root ? Please install first Magisk Manager and after the install in the App you download the Magisk.zip file and flash in TWRP. Voila, the rom is Rooted.

in app quick reboot comes to a little bit problem. When you get fast reboot your ext-sd card can you not see in TB or file explorer
[Samsung Galaxy S9 & S9+ Cross Device Development] get2easy:
Hy Guys

I tested 20 Days this ROM. Finally it's very fast, stable and the Battery Performance is very good.

I have nothing to gripe.

Keep it up DEV
[Samsung Galaxy S9 & S9+ Cross Device Development] gtr33m:
I don't suppose that Google pay works in this ROM?
[Samsung Galaxy S9 & S9+ Cross Device Development] xfirefist:
Thanks for the feedback!
[Samsung Galaxy S9 & S9+ Cross Device Development] xfirefist:
SafetyNet will pass by default so Google pay, Netflix, Snapchat or any other application that checks SafetyNet status will work.

Any further modification such as root may make you unable to use those services or even get you banned, i'm not responsible if that happens so if you decide to use Magisk or any other modification you are on your own meaning i will give minimal support if at all.

PS: Magisk workarounds can be found in countless other threads.
[Samsung Galaxy S9 & S9+ Cross Device Development] get2easy:
Well, well, well it's works. No problems to pay online or shops.

I cant flash this rom 2.1.0 in my g960n variant. When i tried to install that said it s for g960f variant
[Samsung Galaxy S9 & S9+ Cross Device Development] f1mugen:
I have issues with losing saved bluetooth devices and also phone restarts randomly at times.
[Samsung Galaxy S9 & S9+ Cross Device Development] xfirefist:
Hey there, you are the first one to report this issue.

Model number? Did you dirty flash? any other modification?
[Samsung Galaxy S9 & S9+ Cross Device Development] f1mugen:
Did do a dirty flash coming from another android 9.0 rom so will try a clean install once all my stuff is backed up again. G935f no other mods apart from magisk
[Samsung Galaxy S9 & S9+ Cross Device Development] xfirefist:
Its always a good idea to perform a clean installation especially when coming from a different firmware or android version.

Also G935F is the S7 edge but i assume you meant G965F S9+
[Samsung Galaxy S9 & S9+ Cross Device Development] f1mugen:
Yes sorry i mean g965f

Going to do a clean install now. Very happy with the rom so far! [emoji108]
[Samsung Galaxy S9 & S9+ Cross Device Development] nkewk:
Same problem here. Reboots randomly maybe 1-2 times per day and i have to reconnect my AirPods very often.

Was previously on alexndr's latest. Did clean wipe, flashed ROM with the wolf kernel and magisk. I use stericsons BusyBox pro and in magisk i only have Universal GMS Doze, and latest ViperFX 2.7 aswell.

Other than this small problems, i get much better battery time than before. The phone sometimes feel a little bit sluggish, not all the time though.

All in all, i really like this ROM+kernel combo. Keep working on it!! ;)

I have G965F/DS.
[Samsung Galaxy S9 & S9+ Cross Device Development] xfirefist:

Error 255

Error installing zip file
[Samsung Galaxy S9 & S9+ Cross Device Development] xfirefist:
Thank you for reaching out!

I found the problem and im working on it right now, the roms should be updated in a few minutes

Edit: v2.2.1 with the fixed updater is now available.
[Samsung Galaxy S9 & S9+ Cross Device Development] nkewk:
Coming from V2.1.0, is it OK to do dirty flash or should i do clean install again?

Edit: I need to update to DTD with original firmware first??
[Samsung Galaxy S9 & S9+ Cross Device Development] xfirefist:
I updated from 2.1.0 and i have no issues so far other than actually having to fix the updater, you can dirty flash however if you encounter issues you may wish to clean install.

You dont have to update using the official firmware aslong as you are on a Q bootloader.
[Samsung Galaxy S9 & S9+ Cross Device Development] nkewk:
Thank you for responding :)

So turn magisk to core only mode, wipe system, dalvik & cache then flash new version should be good right?
[Samsung Galaxy S9 & S9+ Cross Device Development] xfirefist:
Updating will remove magisk, you will have to flash it again, wipe /system only since the updater wipes dalvik and cache for you.

Goodluck, if you encounter any issues make sure to let me know either by posting or by sending a private message, just make sure to include as many details as you can (model number logs and stuff like that).

OO Yeah i Have two "Freeze" btw. Quickreboot and after in 1 Hour, 3-4 Times
[Samsung Galaxy S9 & S9+ Cross Device Development] nkewk:
I sent you a PM with log from "last_kmsg".

It happened when i was listening to spotify, got a snapchat, opened the snap and then it froze... but i think it is a kernel issue.

I dont know why or how... I have never really gone through logs before and dont really know where to look TBH so please get back to me asap if you want other logs or whatever you need :good:

*EDIT:*

Could it be because kernel wasnt flashed on STOCK kernel? In kernel thread it says warning only flash on stock kernel.

I flashed new version over your previous version, is this the reason? I have to flash stock through Odin before being able to go over to youre latest update?
[Samsung Galaxy S9 & S9+ Cross Device Development] get2easy:
My csc is DBT
[Samsung Galaxy S9 & S9+ Cross Device Development] nkewk:
I dont know how the easiest way to fix it for you would be but i can download latest DBT from sammobile (fast DL) and upload to other mirror so you can maybe use original csc files and flash them with Odin?

Idk if it will help but its a suggestion
[Samsung Galaxy S9 & S9+ Cross Device Development] xfirefist:
TWRP can not backup /data on android 10 roms and it is explained on their website

I had weird problems and i flashed stock with the option 'nand erase' selected. But that was 3 updates before and i still have the G965FXXU7DTAA bootloader. After upgrading to 2.2.1 i have no problems and everything is working well, you may actually have to do the same after you backup your files using a pc or an sd card since twrp has no support for the superpartition present in android 10 (mentiomed in their website too)

Here's a screenshot with the system uptime: http://www.mediafire.com/view/j4gehzga2esobgj/Screenshot_20200515-115523_CPU-Z.jpg/file no crash restart or shutdown since i updated

Instructions:

- Select the option 'nand erase in odin

- Flash the latest stock by filling each file to their respective field

- Let it boot up to the setup screen then turn the device off

- Flash TWRP

- Wipe /system

- Flash v2.2.1 and let it boot up to the setup screeen then shut down and flash magisk
[Samsung Galaxy S9 & S9+ Cross Device Development] nkewk:
So that would work? Is it possible to downgrade bootloader to DTAA from DTD7??? And if it possible should the nand erase box be clicked when im flashing DTAA in Odin?
[Samsung Galaxy S9 & S9+ Cross Device Development] xfirefist:
You dont have to flash DTAA simply use the latest version, nand erase will clean the device and make sure it will work correctly.

My device had issues booting and it would hang on the startup screen even with lineageos so i did what i mentioned above.
[Samsung Galaxy S9 & S9+ Cross Device Development] nkewk:
Did clean flash with stock firmware with nand erase in Odin and then flashed xFire. Seems to work better so far.
[Samsung Galaxy S9 & S9+ Cross Device Development] nkewk:
03:20 16/5-2020:

Still no crash, actually works quite nice so far after doing a full stock firmware flash to (G965FXXS9DTD7) with the nand erase setting-box CHECKED.

I then straight after booting up the stock firmware, reboot to download mode, flash twrp and continued to install the xFireROM & latest Magisk after that.

I will give a new update tomorrow but it is looking nice this ROM (Y)

[Samsung Galaxy S9 & S9+ Cross Device Development] Deadman26:
Noob .. stop blaming the developer.. read OP

Think first..maybe the problem is you and not the developer.. gr8 rom bro.. working well.. cheers mate.. Indian version g9+
[Samsung Galaxy S9 & S9+ Cross Device Development] jpah:
Hi,

Thanks for the great rom.

Couple of things thought.

1. When you restart phone all the bluetooth pairings are gone. Have to do again.

2. If you change connections -> mobile networks -> network mode LTE only, you can not receive or take the normal calls. Have to be (auto connect)

(I don't know if this is how it should be, but just noticed)

3. (Could be that I did have one app which coused the battery drain. So maybe no problem for this one.

Battery drain is quite a big. If I don't use the phone it will take 5-7% per hour and I have no apps to running. (exept the ui and email.)

(and screen resolution is 2220x1080)

4. Could it be possible to make the double tap to sleep and wake in to the phone? I mean tap home screen or lock screen. (It could be Kernel thing I don't know)
[Samsung Galaxy S9 & S9+ Cross Device Development] f1mugen:
Same issues i am having as the above!

I have clean installed but still the phone restarts randomly and when its back on i loose all bluetooth pairings...

Apart from that it works brilliant [emoji106]
[Samsung Galaxy S9 & S9+ Cross Device Development] xfirefist:
I was able to confirm that bluetooth pairings disappear after a restart, im not so sure about battery draining as it could be a problem specific to your unit due to the battery wearing out, my device was new old stock and even after 3-4 months of use i still have less than 100 charge cycles and my battery lasts around 2 to 3 days of light use (chatting and watching a few videos).

Regarding double tap to wake the screen, if you press where the home key is located the screen will wake.

I havent had restart issues ever and im not sure why everyone does, it only happened to me once however i will try and do my best to fix those issues with the next update!

Thank you all for the support.
[Samsung Galaxy S9 & S9+ Cross Device Development] nkewk:
If you have Magisk installed in youre systems, you can download the modules "Bluetooth Library Patcher" for the problem with loosing BT-connections & module "Universal GMS Doze" might help you out with the battery drain.

My phone is going strong man, no problem at all so far after the stock firmware reflash with nand erase with Odin that did it but since then my phone feels way smoother. So i wanted to thank you for the tips earlier in the thread! :good:

Also i just bought an extra SD-card and was going to try to modify my old one to try and use 2 SIM-cards and an SD card at the same time, so if that is not working ATM, i would appreciate if you could look into it until the next release? :D

Cheers
[Samsung Galaxy S9 & S9+ Cross Device Development] jpah:
Hi,

The battery issue was one app so no problem after i removed it.

Home putton tip was good. Thanks!

No restart problems here.
[Samsung Galaxy S9 & S9+ Cross Device Development] f1mugen:
PLEASE HELP!

i updated to latest version and somehow my carrier signals have gone... also in the "software information" it shows BASEBAND VERSION as U "unknown"

its not detecting my simcard and IMEI number is also showing blank!

please help and point me in the right direction to get it sorted. all the TWRP backup restored fine but just these issues.

Thanks
[Samsung Galaxy S9 & S9+ Cross Device Development] xfirefist:
As mentioned above its recommended to flash the latest firmware with odin using the 'nand erase' option.

First backup any important data you may have and download the latest firmware from sammobile, when your download is complete open up odin and put each file to its respective field. (AP to AP BL to Booloader ect)

Go to options and select 'Nand Erase' then connect your device in download mode and hit start.

Once the operation completes and your device restarts let it start up to the setup screen and when it does turn it off put it into download mode and flash TWRP, in TWRP flash the rom and everything should work fine.

Let me know if this helped!
[Samsung Galaxy S9 & S9+ Cross Device Development] f1mugen:
just tried doing the above instructions you gave... when i press stat after placing the right files in AP, BL etc it comes up with a message on my phone stating "SW REV CHECK FAIL (BOOTLOADER) DEVICE: 9, BINARY : 8

please advise further as it just gets stuck there for over 20 mins without movement.
[Samsung Galaxy S9 & S9+ Cross Device Development] xfirefist:
You are trying to flash an earlier version! i told you to get the latest avaliable via sammobile .
[Samsung Galaxy S9 & S9+ Cross Device Development] nkewk:
I can fix fast DL mirror to latest firmware from sammob. You want Multi-CSC firmware or specific?
[Samsung Galaxy S9 & S9+ Cross Device Development] f1mugen:

I was flashing the latest version from sammobiles

But apparently i needed the one older then that... as soon as i flashed that it all restored back to normal and im on xfire latetest version! [emoji108]
[Samsung Galaxy S9 & S9+ Cross Device Development] nkewk:
No problem :) Glad it worked out!
[Samsung Galaxy S9 & S9+ Cross Device Development] f1mugen:
Ok after following instructions above... flashing latest stock rom from sam mobiles via odin and using the nand erase function... i am still having bluetooth devices being lost after reboot (have to pair all of the device again after its lost them...

Got rid of the auto rebooting bug though...

Any insight on what can be causing this...
[Samsung Galaxy S9 & S9+ Cross Device Development] nkewk:
Do you have root with magisk? You can try Bluetooth Library Patcher module if you have magisk. It worked for me. GL

Or are you still on stock?
[Samsung Galaxy S9 & S9+ Cross Device Development] f1mugen:
Just done that now. Fingers crossed... see how it goes [emoji106]
[Samsung Galaxy S9 & S9+ Cross Device Development] nkewk:
