Bug

Guys, have you heard about SGS9+ Selfie Camera bug, that formed after the February firmware update?

I'm talking about auto-focus of the front camera at the very close range. The phone simply does not want to focus on the object when it is too close to the camera. Its a bug (and not only on my side, i've asked plenty of peoples that confirmed the bug), because phone could do it before the February update. Here is two photo samples of the front camera and my face, fuzzy image - Galaxy S9+, sharp image - Galaxy S8.

Hi my friend's s9+ with exynos won't update to 2019 patches (no updates available) . Actually he's on CSC G965FOXM2CRLI (2018-12-19) . He installed with ODIN . How to update via OTA? Any idea? Thank you.
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Tell him to flash the latest build available for his CSC.

If he's in Italy, he just has to flash the latest ITV and after that he will continue getting OTAs again.

I flashed the latest OXM firmware coming from UK BTU and the phone was stuck in bootloop and I had to perform a factory reset to fix it. Please put a warning in your instructions about it. I'm guessing it might of been because coming from another CSC code.

Also samsung info app tells me I am still on UK XEU CSC which means I wont get updates for this firmware.
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
What firmware were you on previously and which CSC file did you use?
[Samsung Galaxy S9+ Guides, News, & Discussion] :
I was on the latest UK BTU which was still OXM. Although samsung info app told me I was on XEU.

I flashed all of it AP, BL etc. After that I was in a bootloop. So I flashed again this time with the file that wipes the phone. Worked after that but im still on XEU csc according to info app.
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
You may not have actually been on BTU.

Correct way to check CSC is Settings > About > Software Information > Service Provider SW Ver.

I've never heard of a bootloop being caused when flashing OXM firmwares.
[Samsung Galaxy S9+ Guides, News, & Discussion] :
I did see an earlier post about flashing btu actually put people on xeu. Maybe it was that. Either way the firmware I flashed was still newer so it is strange. It would get to 'upgrading android apps' finish that then bootloop. I flash my previous firmware back to recover what i could but kept getting process has stopped messages so had to clean flash the latest one in your post to fix it.

My settings say csc is OXM_XEU

---------- Post added at 02:46 PM ---------- Previous post was at 02:27 PM ----------

Just to be certain, is that build for Exynos as that's what my S9+ is? (Living in Ireland)

Thank you.

L.
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Yes. G965F is the Exynos model.

It'll work just fine on your device. Just keep in mind, since it's a downgrade, you will HAVE to wipe all your data.

Downgrading without wiping could get you stuck in a bootloop, and you'll lose data if you haven't backed it up.
[Samsung Galaxy S9+ Guides, News, & Discussion] larkapal:
Thank you. I understand.

This will be the last step in a journey. The S9+ had been upgraded to Pie before it was given to me. And I've no data on it. In order to get call recording to work, which I need, and after much research and reading, I went the TWRP, no-verity, Elementalx, Magisk 18.1 route. Always following instructions to the letter.

The phone would initially power on, I'd set it up but no matter what I did after that, (use smart switch, not use smart switch, Google restore, no Google restore, install apps one by one), invariably I end up eventually powering on into a bootloop. And the front camera never worked, always locking up.

So, boot into TWRP, wipe data, start again with the next attempt.

Now I'm at having wiped data in TWRP, and not bothered installing no-verity, Elementalx, or Magisk 18.1 and just booting the damn thing into Pie, unrooted. The next bootloop, if it happens, will bring me to where I came to you and the flashing of Samsung Oreo to the S9+.

I am hoping, therefore, that the flashing of this Oreo build through Odin, will be the last I'll have to do and the phone will work, finally.

So, just to make sure, I'm going to boot into TWRP, choosing WIPE and FORMAT DATA, power off, boot into Download Mode, and flash the Oreo build you sent me with Odin on my PC.

Will that be correct?

Thank you for your help.

L.
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Format data through TWRP would be unnecessary since downgrading to Oreo would do that anyway if you use the correct CSC file when flashing (read first post).
[Samsung Galaxy S9+ Guides, News, & Discussion] larkapal:
So then I shall only need to connect the phone in download mode and make sure I usr CSC_OXM (OXM CSC file, will wipe your phone)

and DO NOT enter HOME_CSC_OXM (OXM CSC file, will NOT wipe your phone) into Odin.

Thank you for all your replies. They are much appreciated. If I may impose upon you again, can you answer some questions for me, please?

Will flashing this stock Samsung Oreo Rom remove root? (I'm hoping so.)

Will it also remove TWRP? (I'm also hoping so as I just want the phone to be normal again.)

My Knox counter does not seem to have been tripped. I checked with two apps from the playstore: Knox Status Samsung by Brian C, and Phone Info *SAM* by vndnguyen. Will this trip it?

Will it matter that this phone was originally from Vodafone and locked to them?

(I didn't unlock it even though I have the unlock code.)

And, actually, before I started all this, should I have put in a different sim and unlocked it?

I hope you can answer these. And I hope I'm not taking up too much of your time. I'm very, very grateful for your help so far.

Thank you.

L.
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Yes, you'll have to use CSC_OXM when downgrading.

1) Yes, it will remove root, however since the phone has been rooted in the past, the KNOX counter will remain permanently tripped. This means any KNOX related features will never work again. This includes S Health, Samsung Pay and Secure Folder.

2) It will most definitely have been tripped if you flashed TWRP in the past. Go into download mode and it'll show warranty bit counter: 1 instead of 0, or something along those lines.

3) If plan on using it with Vodafone after flashing back to Oreo, it doesn't really matter. However if you do want to use a different carrier, it would be best to unlock first and then flash back to Oreo.
[Samsung Galaxy S9+ Guides, News, & Discussion] larkapal:
I understand regarding the Knox counter.

I hope it all goes well.

Thank you very much for all your help. I'm very grateful.

Also noticed that bixby voice wake up now uses battery, around 18% in my 48hr usage. Guess Samsung wants to devalue older phones again by pushing sh$tty updates so people would buy new S10s...

[Samsung Galaxy S9+ Guides, News, & Discussion] PRINCE2013:
I am hoping for the same. I don't know what Baseband Binary version means. Until now, it was 2, but now it has changed to 3 with this latest update. As can be seen on the first post of this topic, won't be able to roll back to v2 versions after this. I am yet to receive the update (XSG - Emirates CSC) but here's to hoping the Baseband version change is not just a binary kill switch for Samsung to stop devices from downgrading to earlier versions but that it also means an improved Baseband? which would hopefully improve the battery situation.

I am currently getting close to 6 hours 20-30 minutes of SOT with One SIM disabled on purpose. With dual sim, it goes down to 5 Hours 30-45 minutes of SOT. I got the phone only recently and had upgraded to Android Pie without checking first. Anyhow, I downgraded for a few days to Oreo and got SOT of 6 Hours 20-30 minutes with Dual Sims. So here's to hoping things improve now......

I did the Geekbench test right after the Antutu one, so that might be why the score is a bit lower compared to previous tests. But, average is about right.

[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
You can flash the latest ROM from the main post, but you may not get OTA updates unless the same build is released for the TEL CSC.

I'd suggest following the CSC change tutorial linked in post #1 to change your CSC to Germany (DBT). Do that first and then flash this ROM:

https://androidfilehost.com/?fid=1395089523397938751

You'll get OTA updates as soon as they're released since Germany is the first country to get them.

Unfortunately you won't be able to get PET CSC on your phone since that CSC is only available for the S9 Plus sold locally in Peru, which is a different model (SM-G9650).
[Samsung Galaxy S9+ Guides, News, & Discussion] epp1907:
"You'll get OTA updates as soon as they're released since Germany is the first country to get them. "

I successful changed my CSC from MEO to DBT but still on CSD1/CSD1/CSD2 no other OTA yet.
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
That's already the latest build. What more do you want?
[Samsung Galaxy S9+ Guides, News, & Discussion] Cancerbero04:
Thank you for taking the time to respond.

Let me understand this.

If I flash this latest ROM I will be stuck with the TEL csc and furthermore if I want to get any other OTE I would have to wait for TEL to catch up to the same build?

If so, I have read that you can choice to either do a clean wipe while using Odin or use CSC home to keep your current configuration.

My main goal is to get rid of the TEL csc which does not work here.

I also know that the OPS(optus) CSC works well with the current voLTE and Wii calling while using the claro network.

Where can I either get the German CSC and the Australian CSC?

Cheers

Thanks
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Correct. And if TEL doesn't catch up to the same build, but a slightly different one, you'll have to flash that to regain the ability to get OTAs.

While this is also correct, if you want to change CSC, you MUST do a clean wipe. You can't use the non wipe file when switching between CSCs.

Follow the CSC tutorial, change to whatever CSC you'd like.

For example, if you choose to flash OPS, first follow the CSC tutorial and enable OPS, and then use SamFirm to download the latest OPS firmware and flash that on your phone. You'll get OTAs (whenever they're released for OPS).

Alternatively, follow the same thing I said above, but replace OPS with DBT if you're willing to sacrifice VoLTE and WiFi calling for quicker updates.
[Samsung Galaxy S9+ Guides, News, & Discussion] Cancerbero04:
Thanks again for your fast response.

I really need to get VoLTE and Wifi calling here because every time I make a call goes through Claros's 3G network voice and it sounds awful.

I am trying to find the OPS (optus CSC), do you have it on hand? I am unable to use SamFirm due that is not compatible with macOS.
