Thanks a lot mate.

I have another question.

Can I mix the latest ROM here from the Netherlands with the CSC from Optus (OPS) or I need to use either all the files from the latest ROM from the Netherlands and get stucked with TEL CSC or just use all the file from the Optus download link you've provided?

What I am trying to understand is that if it's possible to use part of a different CSC OPS(optus file) with the stock ROM with the Netherlands? I have seen that you need to choose the CSC from Odin before flashing.

Many thanks
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Use all the files from the Optus link that I gave.

DO NOT flash the Netherlands build in the main post because then you won't be able to do the CSC change.
[Samsung Galaxy S9+ Guides, News, & Discussion] Cancerbero04:
Care to explain why the Australian OPS will allow me to change the CSC while the Dutch PHN will not?

Is there a way to know if Claro VoLTE and Wifi calling may work with a different CSC country code?
[Samsung Galaxy S9+ Guides, News, & Discussion] tomesiek:
Any details about that... blocked bootloader? or combination file stop working with this update?
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
CSC change tutorial still uses v2 ROMs, and therefore only a v2 combination will work.

Now that v3 ROMs have started rolling out, I'll have to buy a v3 combination file and then upload it here. I could probably do that sometime next week.
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
See my latest post.

The OPS ROM is still on an older bootloader (v2). The file required to change the CSC is also v2.

The newly released German and Dutch ROMs are on v3. Until I get my hands on a v3 combination file for CSC change, I wouldn't change to DBT or PHN just yet.

As for your question about VoLTE and WiFi calling, I can't say. I'm surprised to know that it works with OPS in the first place.
[Samsung Galaxy S9+ Guides, News, & Discussion] Cancerbero04:
ohh i see know.

The bootloader from OPS is still on older bootloader (V2) but the new German and Dutch CSC are on bootloader (V3) .

Many thanks for that tip.

As per the Australian OPS (Optus), it does work when I insert the Claro's SIM and the VoLTE and Wifi calling are enabled by default (both symbols do show while the TEL CSC does not)

Different images for different storage sizes?

Are there actually different images for different storage sizes? I have a 128GB SM-G965F/DS, but I flashed the G965FXXU2CSC8 zip from March 18th and then LineageOS, and just noticed today that my install thinks it only has 32GB of storage! I asked about this in the LineageOS IRC channel and some folks figured it could just be that I flashed the wrong image. But I would imagine if there were different images for different sized flash storage someone would have mentioned that pretty prominently here, eh? Or am I missing something obvious?
[Samsung Galaxy S9+ Guides, News, & Discussion] maik005:
firmware is the same.

You have to reflash with AP, BL, CP and CSC_OXM ( do not use the HOME_CSC!)

This will erase all data. But then the internal storage will be fully aviable again.
[Samsung Galaxy S9+ Guides, News, & Discussion] tomesiek:
Can you please tell us where you buy from, I would like to know the secure and sure source of combination files for S9, S9+ and Note9 (if possible for middle range Samsung phone as well). Also I can support purchase for our god, XDA community :)

Thanks

I've sent you a PM.
[Samsung Galaxy S9+ Guides, News, & Discussion] Cancerbero04:
Hi,

Can someone please share the best tutorial to change the CSC on a S9+?

I am almost ready.

Cheers.
[Samsung Galaxy S9+ Guides, News, & Discussion] kapooo3:
its on the main post
[Samsung Galaxy S9+ Guides, News, & Discussion] Cancerbero04:
This tutorial imao lacks more info for newbies like myself.

For example,

Step 2) Boot into download mode, and flash the combination file for your device. I had a v2 combination file for S9+ already, so I flashed that.

Download link for v2 combination file for G965F -

How can I boot into download mode and flash the combination file? I would live to see more how to details here.

Thanks.
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Flash it the same way you'd normally flash a stock ROM.

Add combination file to AP tab in Odin, and hit flash.
[Samsung Galaxy S9+ Guides, News, & Discussion] xlmmaarten:
I have an G965F that's stuck on 8.0.

Somehow I've not even gotten any security patch since I got this phone, can I use thin ROM to update or should I contact Samsung first?
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
You can use this to update and regain OTA ability as well.

1) What region are you in?

2) Go to settings > about > software information > service provider SW Ver and post what it says here.

3) Go to the phone dialer app, dial *#1234# and take a screenshot of the window that opens after.
[Samsung Galaxy S9+ Guides, News, & Discussion] MrDusan:
I am interested in this. My friend didn't receive updates since december too. What do we do when we have that info? Can you explain the process?
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Post it here and I can suggest accordingly.
[Samsung Galaxy S9+ Guides, News, & Discussion] xlmmaarten:

3. It says "Connection problem or invalid MMI code."
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Netherlands. Lucky you.

Flash the ROM in the main post and reset your device. You'll start getting OTAs again and you'll be on the newest Pie build.
[Samsung Galaxy S9+ Guides, News, & Discussion] xlmmaarten:
Thanks, will do! If it works that would be amazing.

Since the update G965FXXU2CSC8 the battery life has dropped.

____________________________________________

Hello I'm French, and since the update XEF-G965FXXU2CSC8 the battery life has dropped.

I just updated with XEF-G965FXXU3CSD4

There may be a slight better, but the problem of autonomy is not resolved.

That said, the Samsung S9 + is not known for having a great deal to have a great autonomy.

Hi to all

Did any of you friends have some thing like this on NOTE 9? [YOUTUBE]https://www.youtube.com/watch?v=spy4tJ0G4sE[/YOUTUBE] when CombintaionFile is in use ?

I did install a combination file, change CSC but when I try disconnect phone and try to go in download mode I got this

Power Reset or Unknown Upload Mode

after serious panic attack, lots of reading and mostly luck (pressing all available buttons) I manage to go on normal download mode and install normal ROM with CSC change.

BUT question still stays and it keep drilling hole in my head..... What I did wrong and HOW I fix it?

Is there any solution on this problem?? Please... Need to know HOW to fix it in future :)

THANKS
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Did you flash a CSC file along with the combination file, or just the combination file?
[Samsung Galaxy S9+ Guides, News, & Discussion] tomesiek:
just a combination file, BTW... the one from You :)
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
I tested on Note 9 and S9+, no problems for me.

PM me which one in particular you tried.
[Samsung Galaxy S9+ Guides, News, & Discussion] Leon:
Just receiving second update for April. Pretty weird tho. Anyone knows what is fixing?View attachment 4748649
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Only the CSC got updated. Might be something specific to your region, such as enabling VoLTE / WiFi calling or something similar.
[Samsung Galaxy S9+ Guides, News, & Discussion] Riyad842:
I haven't received march update yet. If i download it with odin my data will be wiped??
[Samsung Galaxy S9+ Guides, News, & Discussion] Lostboy1956:
How will your data be wiped and how are you downloading with Odin...wtf some weird questions on this thread
[Samsung Galaxy S9+ Guides, News, & Discussion] Riyad842:
I mean updating via odin. I got Vietnam version....i haven't received march update yet
[Samsung Galaxy S9+ Guides, News, & Discussion] kxdaorbit:
If you read the 1st page of the OP a lot of your questions will be answered.

Just saying.
[Samsung Galaxy S9+ Guides, News, & Discussion] Cancerbero04:
Hi,

I can not find the right combination file for G965FXXU2CSC8,the one listed launch when using Odin.

I am trying to load the v2 bootloader so I can change the CSC from TEL to OPS.

This one I am not sure if may work./ https://xdaforums.com/galaxy-s9/help/s9-sm-g960f-combination-file-request-t3892826

Thanks.

Edit: I was able to download the COMBINATION_OXM_FA80_G960FXXU2ARG2_OXMFAC_CL13637600_QB18941698_REV01 combination file which is the closest I could find to my CSC8 current version.

Went to the Download mode, uploaded COMBINATION_OXM_FA80_G960FXXU2ARG2_OXMFAC_CL13637600_QB18941698_REV01,Odin checks the file, all in green ready to flash but when I have tried to flash I get something called "repartition failed operation failed".

I am not sure if the combination file I am using is the correct one or I need to use the PIT file or something else.

Will rather wait until i get more help from you guys.
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
You're trying to flash a combination file for a regular S9 on an S9 Plus, that's why it fails.

Why don't you just use the combination I linked in the tutorial?
[Samsung Galaxy S9+ Guides, News, & Discussion] Riyad842:
I have already but....this questions was not mentioned there thats why i asked....i haven't used odin yet...but that guy pretend that he had made the software and knows everything....like him i should know these alao -_-
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Maybe if you actually read the OP properly, you'd find the answer instead of being arrogant and stubborn and expecting everything to be spoon-fed.
[Samsung Galaxy S9+ Guides, News, & Discussion] Cancerbero04:
Pardon me but the only tutorial i recalled that you've advised me to follow is the OPS download link to download the OPS file.

If you are referring to the CHANGE CSC tutorial here: https://xdaforums.com/showpost.php?p=78438552&postcount=2011 DID downloaded that exactly combination file and failed while using odin.

Mind if I ask you as to which tutorial you are referring to and if you could be kind to share the right combination file for my S9+.

Much appreciated.
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
The one from my post is G965F (S9 Plus), but in your post you mentioned using G960F (S9).

Please double check which file you've downloaded.
[Samsung Galaxy S9+ Guides, News, & Discussion] Cancerbero04:
Is this the correct combination file for the S9+ G965F to download?

COMBINATION_OXM_FA80_G965FXXU2ARG2_OXMFAC_CL13637600_QB18941781_REV01_user_mid_noship.tar

What might happen if I flash 0all the OPS files without changing the CSC from TEL to OPS?

Cheers.
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Yes, that's correct.

Nothing will happen.
[Samsung Galaxy S9+ Guides, News, & Discussion] Cancerbero04:
Man,I wish if you could add some more substance.

If I flashing the OPS without changing the TEL CSC, will I be using the TEL or OPS?
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
If you're already on TEL, and you flash OPS, nothing will happen. You'll stay on TEL.
[Samsung Galaxy S9+ Guides, News, & Discussion] Cancerbero04:
Ok then.

Will try again your combination file since we have confirmed is the right one for the s9+.

Just in case,is there another combination file I can use?

'XXS4' another bootloader upgrade so soon after the v3 builds?

Strange.
[Samsung Galaxy S9+ Guides, News, & Discussion] kapooo3:
i have a feeling its because the bootloader might be causeing issues in some places or those countries need a certain one for a certain task
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Download link for XXS4CSDD:

https://androidfilehost.com/?fid=1395089523397955448

Has the same kernel as CSD4 from the main post. Baseband and bootloader are updated, so keep that in mind in case you want to downgrade.
[Samsung Galaxy S9+ Guides, News, & Discussion] Alan1985:
Just downloaded & installed CSDD, anyone else's Samsung keyboard app not working or just mine? The neural beta one works ok, so at least have a workaround for now

Edit - nevermind, I cleared data and cache for the app and it's working again!
[Samsung Galaxy S9+ Guides, News, & Discussion] solokiller11:
Any insights on the battery for this update?

I wonder about that too.
[Samsung Galaxy S9+ Guides, News, & Discussion] Alan1985:
I'm not sure the battery life is much better (if any) to be honest. But I haven't reset my phone in a while (used HOME_CSC each time)
[Samsung Galaxy S9+ Guides, News, & Discussion] Ninja2580:
No kernel related changes.. So performance and battery wise, it should be same as CSD4
[Samsung Galaxy S9+ Guides, News, & Discussion] Murali_ch21:
Is it update zip from 3csd1 to csd4? Sorry for quite some time I miss the thread for s9+. So i just want to double check before flashing.
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Look at the file size. Both of them are 4+ GB so they cannot be update.zip.

Thank you for the reply. In fact I just opened downloaded file and realized it. Thanks for ur work friend. May I check with you if have any patch file.

Hi everybody

I read on this forum that change sim-card can do trick with CSC change. Can anybody recommend a sim-card (available on UK eBay)?

I bought Thailand 5Days Unlimited Data Sim (AIS) sim-card, operator card is MASS TELECOM LTD and I wonder if this card can do that trick. If not please advice me.

I hope that card does not have to be active?

Thanks
[Samsung Galaxy S9+ Guides, News, & Discussion] shiwik:
I have the S9+ (Exynos) that i bought from Dubai. I installed the entire firmware available for India and have been getting regular OTAs since then. However i have noticed my data speed is abysmally low and off-late (last couple months) my call quality has deteriorated (both incoming and outgoing). Folks complain that they don't hear me well or my voice keeps breaking up. I have tried the same SIM on my other phone (Moto One Power) and everything seems to work well. Any pointers on what could be the issue and how could we solve it? I am in the process of downloading the UK firmware to see if that makes a difference but thought i would check with this forum if i am missing anything here.

Advance thanks
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Changing firmware won't help since the hardware is still the same.

Are they 2G, 3G or VoLTE calls?
[Samsung Galaxy S9+ Guides, News, & Discussion] shiwik:
These are regular RIL calls (Airtel). What would be the difference between IN and UK firmwares? Would there be an issue if i flashed UK?
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
There's 0 difference between current Indian firmware and current XEU UK firmware. Both are CSD1, so flashing it would change nothing since the modem is the same and your CSC wouldn't change either.

I know they're RIL calls, but what network is your phone connected to during a call?

To check this, dial another Airtel number, and while the call is running, go back to the dialer and dial *#0011#. There you'll be presented with 2 options, STACK1 and STACK2. They're for each SIM slot, so select whichever SIM slot has the Airtel SIM, and take a screenshot while the call is running.

Then, dial a non-Airtel mobile number and do the same thing.
[Samsung Galaxy S9+ Guides, News, & Discussion] shiwik:
Flashing Indian firmware from the UAE firmware changed the CSC though. Also another noob question - then why have two different set of firmwares? I see the UK firmware is released sooner than the IN firmware.

I tried the option you mentioned below. While the call is on, dialing the code you mentioned does nothing. However if i just dialed the code i got the stack options. I have attached them below
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
I didn't mean to dial them in the in-call dialer, but you figured it out.

The screenshot attached is to a call with another Airtel number? What about calling another network?

Also, it seems like a VoLTE call, which normally should be perfectly fine, but your signal seems quite weak. Does your Motorola phone also support VoLTE?
[Samsung Galaxy S9+ Guides, News, & Discussion] shiwik:
The Moto supports volte too. I feel if i disabled HD calling, the call quality gets even worse. Would you recommend i turn off HD calling?
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
No don't turn it off. The weak LTE signal could be a result of 2 things.

1) Samsung's Exynos modems generally perform worse than Snapdragon.

2) Your carrier has made some changes to the cell tower you're connected to, and you now get weaker signal at the same location where it was fine previously.

If LTE is weak, then 3G might also be weak, which is why your call quality will become even worse.

Have you tried the SIM of another network in your S9+? Try something which has better signal strength to see if the voice crackling and poor audio quality issues persist.
[Samsung Galaxy S9+ Guides, News, & Discussion] shiwik:
Thanks much for your suggestions. Will try that now. Just curious about one of the questions i had asked earlier. If UK and IN firmwares are the same, why are they listed seperately with release dates different. I am almost done downloading the UK firmware. Would that change anything if i installed it? Quite keen to try it

Lastly, does S9+ support carrier aggregation? I have never seen a 4G+, while i see it almost always on my Moto
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Yes, the S9+ supports up to 6CA, which means it can aggregate 6 downlink LTE bands at the same time.

The UK and INS firmwares are listed at different release dates because they're actually released at different dates for different regions. It's the same firmware, but not all regions get it at the same time.

You can try installing it, but like I said, it has the same modem as the latest Indian firmware, and it most likely won't change anything.
[Samsung Galaxy S9+ Guides, News, & Discussion] shiwik:
Much thanks for patiently answering. One last thing - i plan to flash the UK firmware now. Given that they are the same, would i start following the UK release cycle or would it internally direct me to the Indian release cycle?

Will there be any issues if i flashed the UK firmware?
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
If you flash with HOME_CSC, then your phone will literally reboot as is, in it's current state and you'll still be on Indian release schedule, because HOME_CSC will not wipe the phone, and won't change the CSC to UK either since that isn't possible without doing a full reset.

If you flash with CSC_OXM and keep your Indian SIM card inserted, you'll probably switch to UK and then start following UKs update release schedule, however you will lose VoLTE, Samsung Pay, and any other Indian specific features. Your signal strength could probably also be affected since power to the radio is controlled by the CSC which then limits the modem, and UK and EU generally have much more strict regulations regarding this type of stuff.
[Samsung Galaxy S9+ Guides, News, & Discussion] shiwik:
Wouldn't volte work on the UK firmware? Are you indicating that the data speeds might reduce if we move to UK firmware? I just flashed the UK firmware and the phone is still booting up. What are the options if i need to go back to India firmware (CSC)
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
VoLTE will only work if you're on the Indian CSC (INS)

Go to settings > about > software information > service provider SW Ver and post what it says there.
[Samsung Galaxy S9+ Guides, News, & Discussion] shiwik:
I am attaching 2 screenshots here. One of the homescreen that shows volte at the top and the second about the SW information. How do i check which region is this based for?
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Yeah I told you nothing would happen. You flashed the exact same firmware you were already on, so your device stayed on the Indian CSC, and therefore kept the VoLTE functionality.
[Samsung Galaxy S9+ Guides, News, & Discussion] shiwik:
I did not select the HOME, instead selected the CSC for a new flash. I am still a bit unclear which CSC i am on now. Is there a way to find that?

From your signature i gather that you are using the S10+. Is that a worthy upgrade over the S9+? (Just curious)
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Even if you select CSC_OXM, but you have your current regions SIM card still inserted, it won't change CSC.

It says INS/INS,INS/XSG.

The first INS is the currently active CSC, the second 2 are for the current SIM card(s) inserted and the last XSG shows that your device was purchased from the UAE.

The only reason I'd recommend an upgrade to the S10+ would be due to larger battery, and the ultrawide camera lens.
[Samsung Galaxy S9+ Guides, News, & Discussion] shiwik:
Does this mean i am still aligned to the India update schedule?
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Yes it does.

Hi,

I was running G965FXXU2CSB9/G965FOXM2CSB3/G965FXXU2CSB3, ITV region (February 2019 patches) . I opened SamFirm and downloaded the latest available which is G965FXXS3CSD1 (April 2019 patches).

I flashed the firmware with ODIN 3.13.1, the device showed "Optimizing Apps 1 of 144". When reached 144, it rebooted and now it's in a bootloop.

I've done this process multiple times and it's the first time I'm seeing this bootloop.

I was running a Substratum theme, but running the substratum rescue zip does not help.

I have a TWRP DATA and storage backup, but is there another option other than doing a factory reset?
[Samsung Galaxy S9+ Guides, News, & Discussion] thereassaad:
U must disable all substratum before u flash odin rom , now only u can do is format or wipe data if u have twrp .. ..

I also tried to restore the TWRP DATA backup, run substratum recovery zip (both of them) and then reboot the system, but didn't help. Not sure then if Substratum was the cause.

Guys my S9+ gm965f/ds is stuck on samsung logo and very rarely it goes to optimizing apps screen but gets stuck on the last app. I am assuming some update happened overnight and caused it. I have been on stock and auto-update since i got the phone on launch so am annoyed by this issue.

I have tried wiping cache but didnt work and don't want to factory reset and lose all data. Can using odin and flashing the latest firmware solve this? Will it wipe my data if i do this?
