works fine
[Samsung Galaxy S9+ Guides, News, & Discussion] muhammad.b.ali:
I am using G965FXXS3CSD2 and my csc is PAK.

I have a major issue . My whatsapp notifications dont work when the phone screen is off on Wifi only . When I open whastapp all the notifications are accumulated. This doesnt happen on mobile data. I tried flashing different android 9 offcial firmwares through odin . Did a factory reset but still the same issue. I have checked every battery optimization setting but still the problem is there.

I cant use whatsapp , I dont get notifications on wifi after the screen goes off.

I have tried everything i knew. Even the wifi sleep policy thorugh adb which is already set at " always on: even on sleep.

Anyone help please.

this is the same one i have. the problem is in your Swift installer make sure u install system UI and Android system overlays correctly and reboot. if you need more help ask in the swift telegram group since this isn't an update issue :) cheers

Combination File

Is there a Combination file available for Baseband G965FXXS4CSDF - free or purchasable?
[Samsung Galaxy S9+ Guides, News, & Discussion] weretiger:
anyone can help as my phone not geting any update since 1 August 2018!!
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Combination files aren't based on actual firmwares.

You'll never find a Pie based combination file for the S9+ since it was launched with Oreo and combo files are never updated. Wait a few weeks for a v4 file to be available.
[Samsung Galaxy S9+ Guides, News, & Discussion] laughto:
I found a v4 firmware and downloaded - COMBINATION_OXM_FA80_G965FXXU4ASD2_OXMFAC_CL13637600_QB23416070_REV01_user_mid_noship.tar.md5

Managed to load this and change CSC to XSA. Problem now is loading the XSA firmware via Odin. It freezes/hangs when is tries to load recovery.img. Several other files loaded ok.

Any idea how to resolve?
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Probably a bad download. Try removing the .md5 file extension at the end of the AP file from the XSA firmware and then flash it.
[Samsung Galaxy S9+ Guides, News, & Discussion] laughto:
Unfortunately this did not work. Tried different PCs, and different versions of Odin, all to no avail. Always stops at the file recovery.img.

Is it possible that the problem is that I am trying to load G965FXXS3C firmware onto Factory Binary G965FXXU4A?
[Samsung Galaxy S9+ Guides, News, & Discussion] maik005:
Yes.

That is impossible.
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Yes that is the problem. Read post number 2.

You can't downgrade back to older firmwares.
[Samsung Galaxy S9+ Guides, News, & Discussion] laughto:
Ah, ok. So can I load up G965FXXS3CSD1 onto Factory Binary G965FXXU2ARL1?
[Samsung Galaxy S9+ Guides, News, & Discussion] maik005:
YouTube are on the 4er Binary Version.

A downgrade is impossible!

Atm you can only flash the OXM (DBT) Firmware with 4er Binary
[Samsung Galaxy S9+ Guides, News, & Discussion] laughto:
So are you saying that I cannot reflash a V2 Combination file (COMBINATION_OXM_FA80_G965FXXU2ARL1_OXMFAC_CL13637600_QB20860152_REV01_user_mid_noship.tar.md5.rar) and then apply G965FXXS3CSD1 to this?

Sorry for the dumb questions, but very new to this!

Ok, reread post #2 and can see the answer loud and clear - unfortunately!
[Samsung Galaxy S9+ Guides, News, & Discussion] laughto:
OK, one additional question: When a v4 firmware becomes available for XSA (Australia), will I be able to flash this onto an OXM binary?
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Yes.

You can flash any OXM v4 firmware right now. The one in the main post is the latest.
[Samsung Galaxy S9+ Guides, News, & Discussion] maik005:
Right.

Different names but bothe are the same.

Also there is no faked.
[Samsung Galaxy S9+ Guides, News, & Discussion] ramoneluis:
Why we cant get the LTE icon on DBT firmware?

Do you known that?

Thanks
[Samsung Galaxy S9+ Guides, News, & Discussion] maik005:
Ask Samsung why they did that.

It is just optical.
[Samsung Galaxy S9+ Guides, News, & Discussion] ramoneluis:
;)

Thanks
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Depends on the CSC.

Some countries prefer showing 4G/4G+ instead of LTE.

They are exactly the same though.
[Samsung Galaxy S9+ Guides, News, & Discussion] ramoneluis:
Ok. Thanks
[Samsung Galaxy S9+ Guides, News, & Discussion] Tizen99:
My guess that the firmware with G965FXXU1B... is Android 8.1 seems to be true. There are now entries in the Geekbench from the S9 and S9+ with Android 8.1.

https://www.gsmarena.com/samsung_galaxy_s9_running_android_81_spotted_in_benchmarks-news-30882.php

http://browser.geekbench.com/v4/cpu/8165264
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Someone on Reddit claims that 8.1 is in with carriers for being tested and is supposed to release in Europe end of May. I'd take it with a pinch of salt though, for 2 reasons:

1) Geekbench can be fooled with build.prop edits and the person running the benchmark could've been on an AOSP 8.1 based custom ROM.

2) The GS8 received Bxxx Nougat builds but they were still based on 7.0 and not 7.1.1 like people thought it would get.
[Samsung Galaxy S9+ Guides, News, & Discussion] maik005:
1) Also geekbench scores from those Screenshots are very high for the S9(+)

2) the S9(+) is the first Samsung device with project treble.

So fast updates to newer android versions could be possible because as I understood those are much easier then before.
[Samsung Galaxy S9+ Guides, News, & Discussion] t-shock:
I wouldn't trust a random guy from Reddit

Anyone can claim anything, so I don't think we will get 8.1 since Samsung never did (or will as it seems) update to minor incremental android versions

Though, I wish they could just make the battery life a little better and I don't care that much for the android version (atm)
[Samsung Galaxy S9+ Guides, News, & Discussion] Tizen99:
But I don't think Samsung works over 2 months on a G965FXXU1B... firmware, if it's not a big update.

And for the normal S9 is also an entrie on Geekbench with 8.1 and also from the same day with a bit higher score than this from the S9+.

---------- Post added at 10:05 PM ---------- Previous post was at 10:03 PM ----------

That is not true. The S6 came out with 5.0.2 and got a few weeks after the release 5.1.1.

Also the Note 4 got an update from 5.0.1 to 5.1.1.
[Samsung Galaxy S9+ Guides, News, & Discussion] t-shock:
S7 and S8 never received 7.1.1 though

Anyhow, time will prove us which is wrong?
[Samsung Galaxy S9+ Guides, News, & Discussion] Tizen99:
But I think it's very possible that it's 8.1, because since the S9 supports Project Treble, it should be easier than ever to release a newer Android version.
[Samsung Galaxy S9+ Guides, News, & Discussion] FrozenLord:
Today I have finally received the update to build ARD4 on my S9+.

I am using the default CSC of my carrier (Deutsche Telekom, DTM) and had hoped that they would be faster this time around.

Well, I guess I was wrong...
[Samsung Galaxy S9+ Guides, News, & Discussion] Tizen99:
I got it for my DBT device today too.
[Samsung Galaxy S9+ Guides, News, & Discussion] t-shock:
It seems like Samsung isnt working on the G965FXXU1

B

RE2 anymore
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Yeah they switch between BRxx builds and ARxx builds quite often.

This one being tested now will probably end up being the May Patch build.
[Samsung Galaxy S9+ Guides, News, & Discussion] t-shock:
That's pitty

I wanted to see a BRxx build if it had any difference
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
They should rollout eventually, with big changes due to the change in build number. Hopefully they're working on a new kernel.
[Samsung Galaxy S9+ Guides, News, & Discussion] t-shock:
I wish that someone had an "friend" that could access the files and leak it out :D
[Samsung Galaxy S9+ Guides, News, & Discussion] laughto:
But from my limited understanding, XSA is not a member of the Combination OXM.
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Yes it is.

Second post has a list of CSCs that are part of OXM.
[Samsung Galaxy S9+ Guides, News, & Discussion] laughto:
Excellent, I had seen another list of CSCs within OXM that did not include any of the Australian ones.

Thanks for an invaluable resource.

[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Device purchased in UAE and then moved to UK, so probably a build mismatch resulting in no OTA updates.

You'll have to flash the latest available XEU build to restore OTA functionality.

It's the same build that's given in the 2nd post of this thread. You can download it from the links given there or use SamFirm.

Instructions for flashing are in the 1st post.
[Samsung Galaxy S9+ Guides, News, & Discussion] mimo2008:
Thankyou so much...! Now gotta talk to my mother in law about flashing it one question thou would it need a clean install or can i use home csc.?
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
I would definitely recommend a clean install since it's going from Oreo to Pie, but HOME_CSC can work as well.

It changes but I got 4H to 6H SoT with 1-2 days of use. If I watch Netflix on Full brightness and only mobile network SoT is about 4H in 1day of use, less brightness or less mobile network usage increases SoT significantly. It's summer here and sunny outside, so I turn up brighness quite high. That's why I get less SoT than before.

Android Oreo stock rom for build G965FXXU4CSE1

Hi,

[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
June security patch for S9+ is out with build number G965FXXU5CSF2, it comes with quite a large changelog and a new kernel as well. Glad to see Samsung actively working on previous gen models.

Full changelog:
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
For the few S9+ users still around:

I regret to inform you that I will no longer be able to provide download mirror links for the S9+.

It is too time consuming a task to do for a device that I don't own, plus after a recent change in ISPs, I don't have the same download/upload speed that I used to have.

It's been a good run, and while I might delete the MEGA folder eventually, the AFH folder for S9+ firmwares will always stay up. It will get outdated since BL v5 is already released but if anyone for any reason wants older firmwares, they are free to download them from there.

For now, all I can recommend is using Frija. It's a nice user friendly replacement for SamFirm, and the UI has a dark mode as well :P

You can get it here:

https://xdaforums.com/s10-plus/how-to/tool-frija-samsung-firmware-downloader-t3910594

I will still continue to update this thread for as long as I can with firmware update notes and as a platform for discussion for S9+ users.

Cheers :)
[Samsung Galaxy S9+ Guides, News, & Discussion] yochisam14:
Sir MeltdownSpectre do you already have a link on latest firmware on AFH? The June 2019 firmware? Downloading on sammobile sucks.. thanks!
