Hi,

I need your help with flashing Stock Firmware. I have S9+ (G965F DS) with TPRW installed and LineageOS 15.1. It's great system however Im missing a decent camera app so I'd like to revert back to official ROM. I have downloaded G965FXXU2CSA2 and G965FXXU2BRJ8 and I'm running macOS.

I have tried both JOdin 3 and Smart Switch with no result for both firmwares. JOdin says that zip file is corrupted (checked md5, it's the same as on download page) and In order to continue, you must select a valid Odin File. Tried with a different one - same result. Smart Switch tries to connect with S9+ for couple of minutes and then it fails. Emergency Software Recovery shows blank page and reinstalling drivers don't help either.

I run Phone Info to check CSC Code details, however it's all empty (Original CSC's Code, Firmware CSC, Active and Available).

Product Code - SM-G965FZKGXEU

Original CSC's Code - empty

Firmware CSC Code - empty

Active CSC Code - empty

Country CSC Code - empty

Firmware details are as follows:

Bootloader Version: G965FXXU2BRJ8

PDA Version - Empty

CSC Version - Empty

Baseband Version - G965FXXU2BRJ4AZ

To flash LOS15.1 I had to install new vendor image - VENDOR-27_ARI9. Could that be a possible problem?

Appreciate any help, thank You.
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
MacOS is the issue here. Use a Windows PC to flash CSA2 stock.

The CSCs are blank on Lineage because it doesn't use CSCs, so they won't show unless you're on stock or a stock based custom ROM.

i want to revert back to BRJ6, then i want to install the pie update by OTA that avilable for My CSC Only, is that possible .. ?

i am on CSA2 now but i flash it manually, the firmware was not for My Country CSC though, would there be a problem if i revert back to BRJ6 .. ?

thank you in advance ..
[Samsung Galaxy S9+ Guides, News, & Discussion] bdwilk:
I've done it without issue. Not the OTA (I'm rooted) but reverting back isn't a problem.
[Samsung Galaxy S9+ Guides, News, & Discussion] Incarniac:
As bdwilk says, you can do this without problem, however you will want use the non-home CSC if you do this and that will format the phone (do a factory reset), because downgrading without a format / factory reset is even less likely to work without issue than upgrading.

If Pie is out for your country (and carrier), what you can do is flash that Pie firmware manually (and you should be able to use the HOME_CSC and avoid a format of the device). You should then receive OTAs update in the future when they arrive. If it's not out, you could wait until it is and flash manually, then get OTAs after that.
[Samsung Galaxy S9+ Guides, News, & Discussion] AdityaXDA~:
wait, so i update my CSC which is "BRI" with firmware from another CSC which is not "BRI", is that mean i wont be receiving any OTA Update from "BRI" anymore .. ?

and why My VOLTE not working, any solution for VOLTE issue guys ? thank you .. :D
[Samsung Galaxy S9+ Guides, News, & Discussion] Incarniac:
Correct, if you changed your CSC to something else, you won't get OTAs from BRI.

VoLTE is very much dependant on CSC/carrier, so if your VoLTE is not working on your current CSC the only way to fix that is to go back to the correct CSC that the carrier requires for VoLTE to work. For example, on EE in the UK I'd have to be on EVR (EE's CSC) or BTU or XEU; any other CSC won't give me VoLT as those are the only ones EE allows. On O2 UK, which I'm now, I need to be on BTU (which I am) or O2U, TEF or OTF (O2's CSCs) for it to work.
[Samsung Galaxy S9+ Guides, News, & Discussion] Barmenchik:
I was on O2U and now on the default BTU, VoLTE (4G Calling) does not work. In O2 they do not know anything. They say the device should be bought from them !!! :))) At the same time WiFi Calling works.
[Samsung Galaxy S9+ Guides, News, & Discussion] Incarniac:
They will say that, they always do -- frontline customer support really just read from a script and generally have little clue about things in general. Wifi calling is different to 4G calling and one may work while the other doesn't - it's all down to what the carrier allows.

If you're on BTU then VoLTE (4G Calling) should work - it does for me. However, there is no VoLTE icon, but it does work - when making a call it stays connected to 4G and does not drop to 3G (which otherwise happens). There is on more criteria that needs to be met: The area you're in must be VoLTE-enabled -- not all areas are (O2 to have been slower than most to roll out VoLTE). The O2 Coverage Checker usually has information about whether the area has 4G Calling or not.
[Samsung Galaxy S9+ Guides, News, & Discussion] Barmenchik:
Exactly. Being in the coverage area in my city and in Manchester. 4G+ only that I saw. And when you call, 4G changes to H+. And if you enable LTE Only, then you can not call at all!
[Samsung Galaxy S9+ Guides, News, & Discussion] arnes_king:
Hi everyone,

I just wanted to check with you if my csc is OK so that I will receive OTA-a.

Right now I am at the latest BTU firmware CSA2, but stock the phone is BHT firmware (Bosnia with BHT carrier). When I go to settings to check the csc I see SEE/SEE/BHT.

Does this mean that I will not receive OTA updates anymore? If yes, what have I to do to get OTA-s for this firmware?

Hello at everyone, I hope you can help me.

I've a s9 plus, not knox invalidated (still 0x0), that was previously debranded.

Now I've flashed back to its original brand (HUI) android 9 firmware:

https://www.sammobile.com/firmwares/galaxy-s9-plus/SM-G965F/HUI/download/G965FXXU2CRLO/255798/

Flashed went successfull, but now I don't find "HUI/HUI/HUI" but i find "H3G/H3G/HUI" , and samsung info tool says that country is "UK/GB" instead of "Italy"

How can I solve this issue?

I've made everything with my simcard inserted (italian vodafone).

Maybe I need to apply the procedure for changing CSC? will this invalidate the warranty?
[Samsung Galaxy S9+ Guides, News, & Discussion] Barmenchik:
So.. why H3G firmware? If it on Italian Vodafone, must be

https://www.sammobile.com/firmwares/galaxy-s9-plus/SM-G965F/OMN/

Or if it is Unbranded ( SIM Free)

https://www.sammobile.com/firmwares/galaxy-s9-plus/SM-G965F/ITV/

Or am I wrong !!!! Comments please ...

Hi there fellas!

I badly need your help. Can I direcfly flash to the latest software intended for my country? The last one I flashed was for Germany (G965FXXU2CRLF). I got error when I tried to update thru SOFTWARE UPDATE "Your current software isnt supported"
[Samsung Galaxy S9+ Guides, News, & Discussion] iamnotkurtcobain:

[Samsung Galaxy S9+ Guides, News, & Discussion] Wing_Zero85:
Thanks for the answer,

But Don't bother about the Sim card !

The phone was an h3g Italian branded phone.

When it was stock, after buying it, it was:

" Hui/Hui/Hui" and CSc country "Italy"

Now after flashing Italian Android 9 HUI firmware, it is:

" H3g/h3g/h3g" and CSc country "uk/GB"

How can I fix this ?
[Samsung Galaxy S9+ Guides, News, & Discussion] Barmenchik:
Full screenshots please About - Service Provider

CSC1 / CSC2 - the region of the sim card from which the device was initialized / current first sim card - qualify the regional settings of the software (for receiving updates, the availability of Samsung Pay) / the current first sim card

Is it possible to change clock position in the status bar? Can it be moved back on the right as it was on Oreo?
[Samsung Galaxy S9+ Guides, News, & Discussion] spark001uk:
I think the reason the clock has been put on the left in Android Pie, is that more phones are now being made these days with a central "notch" in the display, so this balances left and right sides of the status bar a bit more.

However, I suppose having a setting to put it back if you wanted to wouldn't hurt.

[Samsung Galaxy S9+ Guides, News, & Discussion] nicholas64:
from first page of this thread:

1) Download Odin v3.13.1 - Link

2) Extract the firmware file you just downloaded. You should get 5 files:

AP (System & Recovery)

BL (Bootloader)

CP (Modem / Radio)

CSC_OXM (OXM CSC file, will wipe your phone)

HOME_CSC_OXM (OXM CSC file, will NOT wipe your phone)

3) Add each file to it's respective field in Odin v3.13.1. Use CSC_OXM if you want to do a clean flash and HOME_CSC OXM if you want to keep your apps and data.

4) Reboot your phone in Download / Odin mode with the following button combo:

POWER + VOLUME DOWN + BIXBY

5) Once in download mode, connect your phone to the PC, preferably using the original USB cable you got with your phone. Odin should detect your device and a blue box will show up with the COM port number.

6) Do NOT tick any extra boxes. The only options to be ticked are F.Reset Time and Auto-Reboot.

7) Click the start button, wait for Odin to say 'PASS'. Once the flash is complete, your phone will reboot.
[Samsung Galaxy S9+ Guides, News, & Discussion] MdX MaxX:
So if I'm running a custom ROM/recovery and want to update my firmware without going back to the stock OS, I should be able to simply flash BL and CP and ignore AP/CSC, correct?

I assume that works but I just want to double check as I haven't seen that clearly stated anywhere.
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Yes, in theory that should work fine.

Although, most custom ROM devs do have flashable ZIPs for newer firmwares, so you could probably flash one of those through TWRP instead.

That means the partitioning isn't correct. I guess you changed firmware to one with a different CSC? You'll need to re-flash, and ensure you use the normal CSC file (and not HOME_CSC). This will repartition the phone and reformat it; the effect is the same as a factory reset so it wipes all user data and installed apps, etc.

Hi guys. I really hope someone can help or at least provide some advice. Even pointing me to specific threads because I don't know exactly what to look for but I am going to describe my situation and hopefully you can guide me accordingly.

I recently got an ATT Unlocked SM-G965U on eBay. I am currently in Jamaica and using the device, no coverage problem whatsoever.

The situation is that the security patch is from September 1 and the phone is "currently up to date".

Separate from this, Android pie has rolled out and I was checking Sammobile for official firmware and there are none for ATT under my model number. Will I still receive OTA updates on a unlocked phone for a carrier if i am not a subscriber to their network? This is my first carrier unlocked Samsung as I usually go for the International models so I am not sure if this is all working as intended.

If the answer to the above question is no, or I wish to proceed anyways, which Official stock firmware would be safe to use to flash the unit?

If I am not clear or you require more info, please respond and I will provide you with information needed to further assist me. Thank you for your time.

You are writing in completely wrong topic, this one is dedicated to G965F, which is Exynos powered variant. And yours is G965U, the one with Snapdragon SoC.
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
As [MENTION=1712033]djoxie[/MENTION] said, this thread is for the G965F.

Since you're not in the US, what I can suggest is, to flash the G965U1 ROM on your device. It'll remove the carrier bloatware and you'll have clean unbranded software.

Download the latest Pie firmware for the U1 model and flash it with Odin.

After doing this, you'll get all subsequent OTAs for your device as they're released.
