Combination or factory binary is the file used in Samsung factories and service centers to program phones before sale or return to the customer.

It does work as long as the Bootloader revision is the same. If you are on the May update or older, it will work just fine.

You flash it with Odin like you would a normal ROM, and it will boot up with very limited functionality. Then follow the RealTerm tutorial and set the CSC to whatever you'd like.

If it's TPA, then once you're done changing the CSC, flash your device to the ASE7 May build and let it boot up, go through the setup wizard and it should say TPA/TPA,TPA/TPA.

Once you've confirmed that TPA is the active CSC, then you're good to go. Everything will work normally and you will get OTA updates as well.

I'm uploading the factory binary now, but since I don't recommend publicly posting the link, I'll PM it to you once it's done.

Hey guys, sorry if this has been asked and answered a thousand times but I'm a bit paranoid after doing the research and as this is a my new phone I don't want to do anything wrong.

I bought a carrier locked S10+ with MOB CSC, A1 carrier in Austria. The phone is now carrier unlocked and on latest MOB firmware which is May 1. sec. lvl. I want to flash the lastest released MULTI-CSC G975FXXU2ASF3 firmware from the firmware thread. As the phone is new and I didn't even set it up I planned to flash with CSC_OXM. From my understanding the phone will change to the SIMs CSC after the flash. Am I correct?

Am I able to do this as planned or is it not possible to flash MULTI-CSC over my MOB-CSC? Will I be able to receive OTA updates or do I need to flash everytime with ODIN after CSC change? Thanks in advance!
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
Please read the first post of this thread.

There are many FAQs that can answer your questions.
[Samsung Galaxy S10+ Guides, News, & Discussion] VertigoOneX:
Ok, I read everythig again. Here's still a question regarding Q6.

Which CSC will the phone have after flashing? Is there a way for me to choose?
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
If your phone is region locked, it will most likely have the default CSC for unbranded firmwares, which is XEF (France).

If it's not region locked, it will automatically switch to the unbranded CSC for your region which is ATO.
[Samsung Galaxy S10+ Guides, News, & Discussion] VertigoOneX:
I flashed and the CSC right now is ATO/ATO, XEF/MOB.

Is this the way it should be? Also is there a way to have OTAs with this multi CSC over my carrier CSC or is this the only way? Thanks again for your help!
[Samsung Galaxy S10+ Guides, News, & Discussion] readymarc:
I'm from Trinidad also, my CSC TTT/TPA. Would I get updates? Or do I need to change my CSC also. I have been flashing manually since I received my device
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
Did you flash the ASF3 June build, or the ASE7 May build?

If you flashed the June build, you will get OTAs if the same exact build is released for the ATO CSC. There is an FAQ regarding exactly this in the main post I think.

You'll have to manually flash each update. Unfortunately CSC change is not yet available on the S10 lineup.
[Samsung Galaxy S10+ Guides, News, & Discussion] VertigoOneX:
Yes I flashed the newest June build. Ok nice, it did say my software is the newest and not it's not compatible as I've read from others who can't do OTA, but I still wasn't sure. Thank you for your help I really appreciate it!
[Samsung Galaxy S10+ Guides, News, & Discussion] vibrantliker:
Maybe someone can help as I am now in a bootloop.

I am rooted with magisk and wanted to upgrade from ASE7 to ASF3 so I:

downloaded the formware from Frija

patched the AP file via magisk

patched twrp img file via magisk (twrp-beyond2lte-3.3.1-3.1_ianmacd)

replaced the recovery in the ap file with the patched one

flashed via odin BL,AP(patched magisk file)CP, and Home_CSC

rebooted to recovery from odin, now bootloop

Im having trouble trying to flash ZTO Rom on my S10+. Phone was UPO/UPO,UPO/UPO and everytime i try to flash ZTO it doesnt change anything.

I flashed OXM and got XEF/XEF,XEF/UPO. Anyone knows what i can do to get ZTO? Ive tried flashing with SIM on and off, nothing works. Also *#272 imei isnt working, says unknown application when i try to run it

My problem might be the same as [MENTION=6612375]Gdefreitas[/MENTION]. Can [MENTION=5063250]MeltdownSpectre[/MENTION] help me with the RealTerm thing? Has it worked for Gdefreitas?
[Samsung Galaxy S10+ Guides, News, & Discussion] Gdefreitas:
No, it hasn't worked. As of now, I haven't found another way to change it without having a sim card from another region.
[Samsung Galaxy S10+ Guides, News, & Discussion] filipe.dultra:
But I do have a SIM card for the region im trying to switch to. Im currently using it but it still wont change.
[Samsung Galaxy S10+ Guides, News, & Discussion] Gdefreitas:
Then I'm not too sure. It's the only thing I've seen persons said that worked, haven't been able to try it myself as I don't have any other sim card. I have tried a lot of other ways though, and so far nothing has worked. You may just have to wait a while and see if anyone figures out a way to change the CSC, or continue to flash the updates manually for the time being. If you find a way please do let me know as well, I'm still looking.
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
Region locked phone.

When you flash an OXM firmware, it switches to XEF by default.
[Samsung Galaxy S10+ Guides, News, & Discussion] filipe.dultra:
Nothing I can do then?
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
Unfortunately not.

All UPO phones are region locked.

You're the 3rd person with a UPO device asking if they can change the CSC.

Sadly Samsung has stopped the combination file from being flashed on the S10 series as well so even the RealTerm method won't work in this case.
[Samsung Galaxy S10+ Guides, News, & Discussion] vibrantliker:
Maybe someone can help me. I seemed to have borked my phone. I kept getting "Google is Stopping" with no way to fix it, so I tried reflashing my firmware in odin. After I loaded all the files and hit start, I realized I didn't untick auto reboot, so I tried aborting the installation and ended up with screen (I've had it before and got out of it by still flashing in Odin, but now, if I try to reflash firmware while in this screen, it's stuck on SYSTEM in odin.

Any help appreciated!
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
Use a different USB cable / port. Preferably a USB2.0 port if it's available.

Also you're supposed to keep auto reboot ticked.
[Samsung Galaxy S10+ Guides, News, & Discussion] enjwer:
I have the S10+ bought from Best Buy. I just found out that HD Video calls are impossible, and I'd like to change that by switching to the Verizon build.

A few questions:

1. I found two versions of Odin: (a) Odin3-v3.13.1 and (b) Odin3-v3.13.3. Does it matter which one I use?

2. When I run Odin, I get a warning "to delete your Google account(Samsung account) before downloading the binary. It is not possible to use the device without unlocking. Changing the partition without unlocking will cause problems." What does this mean and what should I be aware of?

3. I can't get Frija to download the files I need. I'm typing in Model SM-G975U (or SM-G975U1) and CSC VZW. Why won't this work? Frija doesn't autodetect my device.

4. According to one webpage, I need to put the phone in Developer Mode first by tapping some options in settings. Is this true or can I skip this step?

5. What does it mean to "trip KNOX" and should I be worried about this?

6. I have read some questions about "v1 bootloader" instead of v2. What does this mean and should it concern me?

Thank you in advance.
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
Go to settings > about > software information > service provider SW Ver

What does it show there?

No it doesn't. Minot differences, but they both work just fine.

Just make sure to either manually remove your Google and Samsung account before flashing, or do a factory reset the normal way, by going into settings and doing a reset.

For some weird reason, VZW firmwares don't show up on Samsung servers anymore. Makes me think they've gone the same route as AT&T and they use their own dedicated server for hosting updates and whatnot.

You can skip it. It's not necessary.

Don't want to go into to too much detail, but it's almost impossible to do this on a G975U. Nothing to worry about.

Just new bootloader versions that Samsung releases to patch security exploits. Doesn't really concern what you're trying to achieve. But it's always good to know.
[Samsung Galaxy S10+ Guides, News, & Discussion] enjwer:
It shows:

SAOMC_SM-G975U1_OYM_VZW_PP_0019

[2nd line deleted - is this specific to my phone?]

VZW/VZW/XAA

So I should just logout of my Google account? Is that enough or I need to do something more? What happens if I don't? If I'm hoping to use the build that doesn't wipe out all of my data and apps, I still need to do this, right?

Is there a better place to get the firmware that's safe? Does it matter what version of the firmware I install so long as it is a Verizon S10+ build?

Thanks again.
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
Okay, so VZW/VZW/XAA means your device is already on the Verizon software.

However, you're on G975U1 which is the unlocked version.

You'll want to flash G975U, and run a factory reset so you can use the Verizon branded ROM.

I'm not quite sure how to go about that, so you'll have to create a separate thread so the other G975U users can help you out.

This thread is for the G975F which works a bit differently to US models.

Hi guys. I have a question. Is there any way to flash back G975FXXU1ASD5 if G975FXXU2ASF3 is flashed?

When I try to do it, I recieve this message : SW REV CHECK FAIL(BOOTLOADER) DEVICE 2 BINARY 1
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
No you can not.

ASF3 is a 'U2' firmware, and ASD5 is a 'U1' firmware.

Downgrading is not possible.
[Samsung Galaxy S10+ Guides, News, & Discussion] hccssn:
hello,

I would like to kindly ask you.

I have a branded Orange Slovakia SGS10+, CSC: ORS. System settings page shows me: ORS/ORS, ORS/ORS.

Once I check the available CSCs on the phone via PhoneInfo, I see just these: AMO, FTM, OPV, oro, ORS.

I would like to change the CSC and the firmware to the unbranded ORX: Slovakia, which has multi CSC inside.

Is this, please, possible to do? If yes, how please? I am new at samsung.

The ORS is bad on updates, it is still on May on my device and no new update available, even if there is already june and july updates available.

The ORX has already 2 newer versions than ORS and my friend, who purchased an unbranded model, has already the newest installed by OTA.
[Samsung Galaxy S10+ Guides, News, & Discussion] rmn.br:
Hi,

it is already explained in FAQ at first post.

Q6) I am on a carrier firmware, can I flash this firmware?

Short answer: Yes, but all your data will be erased.

Detailed answer: If you are on a carrier firmware that is not part of the OXM multi-CSC list given in the answer for Q2, then you can still flash OXM firmwares, but you will not have the option of using the HOME_CSC file to retain your data. You must wipe your data when switching from a carrier firmware to an unbranded firmware. Once you are on the unbranded OXM firmware, you can use HOME_CSC to upgrade without wiping data.

...there is almost everything. for further answers I will edit this post

edit: u need use AUT. btw u cannot change CSC to ORX, its not possible. You can flash ORX but your CSC will be BTU or XEF... yes after that u will be receving OTA for BTU or XEF. No, there is not difference between ORX and AUT its only for OTA location delivering and market sell. Good luck

[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:

It has the latest firmware available for UK unlocked.
[Samsung Galaxy S10+ Guides, News, & Discussion] kevinireland11:
I think my csc is (EVA)EE...so if I flash the unlocked version (BTU) would that be ok do u think?

I'm use to oneplus devices lol

Edit yeah they are multi csc actualy just seen it rhere
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
It will most likely switch to BTU automatically once it sees that you have a UK SIM card in the device.

After flashing, set up the phone (without an account) and do a factory reset again with the SIM inserted just to make sure.
[Samsung Galaxy S10+ Guides, News, & Discussion] hccssn:
hello,

thank you for the answer, I tried now the ORX version - Slovakia.

My SIM got changed, I had the message about it and phone restart.

Now my CSC is: XEF/ORX, XEF/ORS

Before I had all ORS.

Is that please OK?

Well, the XEF is France based on your list. How it become to the mentioned XEF? How did it happen? Why France, if it was Slovak before??

Thank you.
[Samsung Galaxy S10+ Guides, News, & Discussion] rmn.br:
Why is CSC XEF you must ask Samsung and it's all fine. Don't know why is /ORX, /ORS (maybe coz Orange?)
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
If you reset your device one more time, it will change to ORX/ORX,XEF/ORS.

For some reason, when switching from carrier ROM to unlocked ROM, it defaults to XEF (France) automatically.

first time i read the Title i don't interested to read the thread cause i use Odin all the time but really the FAQs its very impotent and a lot of new information to my thank you
[Samsung Galaxy S10+ Guides, News, & Discussion] tiho5:
Very good thread. Thank you.

I've always used custom roms on all my devices so far and don't have much knowledge of stock FW stuff.

Nowadays stock is good enough for me and I am fine with rooted stock plus TWRP.

I want to ask something. It's covered by the FAQ in the OP. Number 4 and 5, I think. However I want to be sure.

Say I miss to update 10 FW. My data is something I want to keep. And I'll use the home SCS.

If I update straight from my old FW to the latest one which is 10 versions up. Is my data going to be OK? Is it going to be "prepared" so to speak to work with such a future FW. Is this going to be all right? Provided that even the Android version might have been changed to a new version.

Thanks again for the great work on this thread.
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
Flashing within the same OS version with HOME_CSC to retain data is normally okay. However, sometimes people run into weird issues like the phone suddenly showing 32 GB of internal storage instead of the actual amount, and the only way to fix this is by doing a factory reset. Keep that in mind when you're flashing.

In the rare occasion that I do use HOME_CSC myself, I always take a backup beforehand in case something goes wrong.

Flashing from Android 9.0 to 10 for example is also possible with HOME_CSC to retain data, but I would advise against it. Clean flashing a new major OS update or at least doing a factory reset after taking the OTA is always recommended for the best experience.
[Samsung Galaxy S10+ Guides, News, & Discussion] DanQ:
Changing the CSC

I live in US with AT&T carrier and my phone has a CSC as XSG/XSG,XSG/XSG. I'm assuming the CSC could affect the network performance??? If that so, does anyone has a suggestion on which CSC will be the best to go for, to increase network performance and get Samsung Pay working properly and etc....?
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
You're using a Middle Eastern variant in the US.

There are no US CSCs available for the variant that you have.

You'll have to buy a G975U locally for optimal network performance and Samsung Pay.

[Samsung Galaxy S10+ Guides, News, & Discussion] superleeds27:
So, assuming I've read all this correctly.

Device is BTU/BTU BTU/BTU

Flashing the XEO build (ASH6) whilst retaining data would be fine.

OTA going forward will only work if BTU gets the (ASH6) build. If it doesn't, i'd have to then flash the latest version of the BTU FW for OTA's to kick back in.

Correct?
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
Spot on. 100% correct.

I wish others would do more research like this before posting.
[Samsung Galaxy S10+ Guides, News, & Discussion] superleeds27:
Thought so. Just wanted to triple check!

It's good to know we can do that now, rather than holding out for an OTA to drop.

[Samsung Galaxy S10+ Guides, News, & Discussion] Virgo_Guy:
If the same build that you are about to flash(i.e. latest September build "G975FXXU3ASIG") is also released to your active CSC(XEU in your case) then you will receive consecutive OTA updates. But if a different build is released, then first you will have to download and flash that build first to receive future OTA updates.

I get you thanks for the reply much appreciated
[Samsung Galaxy S10+ Guides, News, & Discussion] mtm1401:
So if I flash ASH6, and then the for BTU, will a future OTA update change the CSC back to BTU or will it stay XEF unless specifically flashed?

Thanks
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
What's your current CSC?

If it's BTU, it will stay BTU unless you insert a SIM card from another country.

I still have a doubt about CSC (it is my first Samsung)

My phone has TIM CSC (Italian brand operator), can I flash the latest ITV (Italy unbranded) version using the home_csc without losing data? In another thread someone told me yes, but as per FAQ seems I can't

If I can't, can I use "samkey" to change CSC to ITV and then flash the latest ITV firmware?
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
You can't flash with HOME_CSC. I made these FAQs for a reason.

I'd recommend a clean flash to ITV unbranded.

I don't know what SamKey is, so I can't say anything about that.
[Samsung Galaxy S10+ Guides, News, & Discussion] andQlimax:
Thanks for the reply, does your answer is valid even if ITV csc has TIM (my current csc) as available csc? Or what the attached screen means then?

Ps. SamKey is a tool that claim to change csc without root and without loosing data by doing some reverse code calculation (I don't have idea), some users in the s10 (non plus) forum have tried with success.. But still I cannot clear understand all the complications, many csc around and not sure if I can completely revert in case I need warranty
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
ITV shows 'TIM' in brackets because ITV is compatible with all Italian carriers, including TIM.

Not related to the carrier CSC for TIM. Samsung should have made this less confusing :P

If you flash to ITV, you can flash back to TIM if you want to.
