Since the official firmware thread by @henklbr is flooded with posts asking how to flash rather than actual firmware update talk, this thread can be used for that instead.
Here's the Odin flashing guide at the beginning of the thread which nobody will read.
How to flash the stock Odin flashable firmware:
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:
-Power off your Galaxy S10/S10+
-Connect the cable to your PC, but do not plug it into your phone yet
-Hold Volume Down + Bixby button and plug the Type C cable into your phone while holding down those buttons
-You will get a warning on your screen, press 'Continue'
5) Once in download mode, 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 and they are enabled by default.
7) Click the start button, wait for Odin to say 'PASS'. Once the flash is complete, your phone will reboot automatically.
Flashing Tips:
1) Always try to use the OEM Samsung USB-C cable when flashing.
2) Install Samsung Smart Switch before flashing, it automatically installs the latest Samsung USB drivers. However, make sure Smart Switch is CLOSED when you are flashing your device with Odin.
3) Try not to have too many other applications running if you have a PC with low RAM as Odin can consume a lot of memory sometimes, and the last thing you need is for your PC to freeze in the middle of a flash.
This is what a successful flash log on Odin looks like for an S10+ ----> Pastebin Link

Before asking a question below, read the FAQs, your question has most probably already been answered.
Q1) Will this trip KNOX, and will I lose my warranty?
Short answer: No
Detailed answer: KNOX counter will remain at 0x0 and warranty stays valid as well.
However, some service centers might note regional differences between builds based on the latest build available for your CSC, indicating that the phone has been flashed, so if you're sending your device in for a service/repair/replacement, then I'd suggest flashing to the latest build available for your home country's CSC. Usually not required though, so not a big deal.
--------------------------------------------------------------------------------------------------------
Q2) What if the firmware build number mentioned above is not available for my CSC, can I still flash it?
Short answer: Yes, but that is subject to your current active CSC. Read detailed answer below.
Detailed answer: See this list --- > LINK
--------------------------------------------------------------------------------------------------------
Q3) I flashed 'ASxx' build, but now I can't get OTAs for a newer build that's available on my CSC?
Short answer: The build you are currently running on your device was never released for your CSC, so no subsequent OTA file is available on the server.
Detailed answer: This is due to Samsung's stupid update rollout methods. Go to SamMobile, select SM-G975F and find your region in the list, and flash whatever the latest build is to regain the ability to receive OTAs.
--------------------------------------------------------------------------------------------------------
Q4) Can I flash the ROM in the main post without flashing the builds that came before it?
Short answer: Yes.
Detailed answer: The firmwares available for download using SamFirm or Frija are full firmware files. Flashing them will manually flash (and update, if necessary) every partition on your phone. So you could be on the oldest firmware ever released for the S10+, and flash directly to the latest one without having to flash any builds released in between.
--------------------------------------------------------------------------------------------------------
Q5) Can I flash without wiping my data?
Short answer: Yes.
Detailed answer: If you've gotten to this question, you clearly haven't read the Odin flashing instructions.
If you want to flash and retain all the data on your phone, you can choose to use the HOME_CSC file when flashing. This will only upgrade your phone to the newer firmware, but allow you to keep all your data.
--------------------------------------------------------------------------------------------------------
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.
--------------------------------------------------------------------------------------------------------
Q7) If I flash AUT region firmware on my DBT device, will it affect my ability to get OTA updates?
Short answer: Maybe, maybe not.
Detailed answer: Read the answer of Q3.
--------------------------------------------------------------------------------------------------------
Q8) Is there any risk of flashing?
Short answer:No, not really.
Detailed answer: If you are not experienced with flashing but would still like to flash your phone, make sure to be very very careful and don't miss any steps in the process. There is usually no risk, and it is very hard to permanently brick your device when flashing stock ROMs. There is a chance of data loss if the flash is interrupted.
--------------------------------------------------------------------------------------------------------
Q9) Why does the window says 'FAIL' instead of PASS?
Short answer: Could be for multiple reasons, see detailed answer.
Detailed answer: If a flash fails, always make sure to copy and paste your Odin log here so we can see where and why the flash failed.
The Odin flash log can be seen on the bottom left of the Odin window, see this screenshot ---> Odin 3.13.1 screenshot
--------------------------------------------------------------------------------------------------------
Q10) Why does the Odin log show that the flash failed at sboot.bin.lz4?
Short answer: The version of your Odin is not compatible with newer firmwares that use lz4 compression.
Detailed answer: Samsung started using .lz4 compression with Oreo firmwares, so older versions of Odin can't be used.
Use Odin v3.13.1 (Download link) for flashing on the S10+.
--------------------------------------------------------------------------------------------------------
Q11) Why does the Odin flash log show FAIL (XmitDataWrite)?
Short answer: There was an issue flashing the AP (System) file to your device. Read detailed answer on how to solve.
Detailed answer: This is usually due to an issue with the USB port or the cable being used to flash the device. If you are using a USB 3.0 port on your PC / laptop, try switching to a USB 2.0 port instead. If you don't have a USB 2.0 port available, change the cable. Some cables don't handle large file transfers well. Preferably use the OEM Samsung cable that you got in the box of your phone.
--------------------------------------------------------------------------------------------------------
Q12) Where can I download the latest S10+ (SM-G975F) firmwares?
Answer: You can use Frija which downloads the firmwares straight from Samsung servers - Link
--------------------------------------------------------------------------------------------------------
Q13) What do the CSCs in the settings menu mean?
Answer: See below.
Single SIM device:
If you have a Single SIM device, it will show 3 CSCs in the settings menu, in the following format:
DBT/DBT/DBT
1st CSC = active CSC (You will get OTAs for this CSC and any features like Samsung Pay, VoLTE, WiFi calling are dependent on the active CSC)
2nd CSC = CSC of your SIM card (In case your SIM card is from a different region than your active CSC, this will be different from the active CSC)
3rd CSC = Hardware CSC of your device (For example, you purchased the device in Germany, but are living in the Netherlands, it will show PHN/PHN/DBT)
It is not possible to change the hardware CSC, and it has 0 effect on the device's functionality or when it will get OTA updates. It is simply an indicator for what market the device was intended for sale in.
Dual SIM device:
If you have a Dual SIM device, it will show 4 CSCs in the settings menu, in the following format:
DBT/DBT,DBT/DBT
1st CSC = active CSC (You will get OTAs for this CSC and any features like Samsung Pay, VoLTE, WiFi calling are dependent on the active CSC)
2nd CSC = CSC of your SIM card (In case your SIM card is from a different region than your active CSC, this will be different from the active CSC)
3rd CSC = CSC of your SIM card in SIM slot 2
4th CSC = Hardware CSC of your device (For example, you purchased the device in Germany, but are living in the Netherlands, it will show PHN/PHN,PHN/DBT)
It is not possible to change the hardware CSC, and it has 0 effect on the device's functionality or when it will get OTA updates. It is simply an indicator for what market the device was intended for sale in.
--------------------------------------------------------------------------------------------------------
Q14) Why did my CSC change to XEF (France) after flashing from a carrier ROM to the unlocked ROM?
Answer: For OXM firmwares on the S10 series, when flashing from a non-OXM ROM (such as a carrier ROM) to an OXM multi-CSC ROM, the active CSC defaults to XEF.
Detailed answer: For devices that are region locked, once you flash from carrier to unlocked, it will stay on XEF. There is no way to change CSC yet without root.
For devices that are not region locked, it will change to XEF, but to switch to the unlocked CSC for your region, remove your SIM card, insert it again and do a factory reset from the settings menu.
--------------------------------------------------------------------------------------------------------
Q15) Can I downgrade to an older build?
Answer: It depends on your current build. Sometimes you can downgrade, sometimes you can not. Read detailed answer to check.
Detailed answer:
You have to see the bootloader version of your current build. Samsung tends to upgrade bootloader versions regularly so downgrading is not always possible.
For example if your current build is G975FXXU3ASG8, and you want to downgrade to G975FXXU2ASF3, it will not be possible.
Moving from 'XXU3' to 'XXU2' is not possible since XXU2 is an older bootloader version, and because of Samsung's downgrade protection, it will not allow the older version to be flashed.
When attempting to flash, Odin will show 'FAIL' in the flash window, and the bootloader screen on your device will display this error:
SW REV CHECK FAIL(BOOTLOADER) DEVICE: 3, BINARY: 2
This is showing that the device is currently on a v3 build, and the build being flashed is v2, so it will reject the file and abort the flash immediately.
If however you want to downgrade from G975FXXU3ASG8 to G975FXXU3ASG2, you are free to do so, since both builds are labeled 'XXU3' and are on the same bootloader version (i.e: v3).
Note: Some builds will be labeled 'XXS', and the same reasoning applies to those builds as well. If the bootloader version is different, you can not downgrade.
--------------------------------------------------------------------------------------------------------
Q16) Why are some builds labeled 'XXU', whereas some builds are labeled 'XXS'?
Answer:
XXU builds are usually larger updates, they usually include security patches, kernel changes and other under the hood fixes. When new features are added, they are also usually shipped with 'XXU' builds.
XXS builds are maintenance releases. They just include security patches and nothing more. OTA sizes for XXS builds are usually significantly smaller as well. In some cases, exceptions can be made and new kernels can be included with XXS builds as well.
These changes are usually discussed in the stock firmware thread for the device.
For newly released devices in the first 6-8 months, almost all builds are XXU since Samsung is actively working on improving the device.
For devices nearing EOL, Samsung is only fulfilling its obligation to provide security patches and no new features, so most builds are XXS.
--------------------------------------------------------------------------------------------------------
First! Just installed ASE7 (AUT) over ASE6 (BTU) using HOME_CSC (I was already on BTU). Very nice it is like real OTA because bloatware wasn't installed. Phone working...
additional info: My S10 (not +) was branded in Czech T-Mobile TMZ/TMZ,TMZ/TMZ now is BTU/BTU,BTU/TMZ and all is good. Still obserwing stuff around Samsung
Flashing for dummies guide is very useful. Thanks
To keep root when flashing new firmware, you patch the AP file in Magisk then use that patched .tar file in the AP slot in odin, right?

I haven't rooted my phone, but have read about it, and yes that seems to be the way to go about it.
Lots of people complaining that they have to patch the entire 5 GB AP file.
The list of CSCs included in the OXM multi-CSC has now been updated for the Galaxy S10/S10+.

Hi there,
My OPS (OPTUS) Is a multi CSC carrier but since I do not longer use it in Australia but rather in South America,I would like to change my CSC to perhaps DBT so I can get the latest OTA updates.
Is it possible to change my CSC?
I use the Claro SIM here and I have successfully updated the AS7 firmware.
Thanks.

Your device seems to be region locked to OPS which is why it isn't offering automatic CSC change.
I need to experiment with the complicated CSC change method on my own S10+ first and then I'll post it here.
My S10+ has the active CSC code as TTT, the device doesn't receive OTA software updates and I notice your listing has TTT as N/A, would this be why I haven't received the OTA updates? I've flashed the latest ones manually. I've tried to change the CSC by flashing XEF, BTU, SKR, TPA and EON as I'm from Trinidad, but nothing has changed the CSC, all my other Samsung devices, including my other S10+ has the active CSC as TPA and they receive updates. All are unlocked and have sims from the same carrier. Any ideas as to how to change it to get OTA updates?

Did you buy the device from a carrier, or unlocked?
I've got TTT listed as N/A since I wasn't aware which country / carrier it belonged to.

It's an unlocked device that's purchased from a retailer, I'm not sure where their supplier is located, my guess would be Panama. TTT is Trinidad and Tobago, I'm from Trinidad, but instead of my device CSC being TPA like the other devices that gets the update, mine is TTT/TTT, TTT/TPA. I just would like to change it to TPA to be able to get updates, or even EON which is the CSC for firmwares for Trinidad.

What carrier are you using in Trinidad?
Maybe TTT is for a specific carrier, and since that's part of OXM, your phone automatically selects that CSC.
Although it is very weird that the FOTA server doesn't list any OTAs for TTT, which means you'll have to flash every update manually.

I'm using Bmobile, which is the carrier all my other devices use as well, and they show the CSC as TPA, so they receive the updates. Their is no TTT firmware for the S10+, but there is for the S10. I assumed that would mean no firmware updates, and I only received one, but that was when I now purchased the phone, after that I had to factory reset the phone and since then, I haven't gotten any OTAs. Is there anyway to change the CSC to TPA? I've tried flashing the other firmwares, the BTU, XEF, SKR, but none of them changed the CSC from TTT. Any suggestions?

Can you try swapping the SIM card from another phone of yours to the S10+?
After inserting the SIM card, restart the phone and check what it shows under settings > about > software information > service provider SW Ver.

I've tried that, even tried from the other carrier available in my country, but it still doesn't change. It remains as TTT. It's the dual sim version, although I've never even inserted a second sim into it, that slot shows TTT as well.

I saw another one of your posts where it mentioned using RealTerm to change the CSC, can this be used with my device, and if so, how do I go about doing it? Thanks for any assistance you may be able to render.

In theory the RealTerm method should work just fine. All you'll need is a combination / factory binary file for the G975F. The rest of the tutorial should work the same way.
I think I have the file, I'll check and upload it later today.

OK, thanks a lot, I'll give it a try. Just for the sake of knowing, could you explain what exactly the combination file is, and does it work on any software version of the device, or is it firmware specific? In other words, will it work on the ASE7 build that I'm presently on? Also, will I continue to get OTA updates after switching the CSC this way?

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!
Hi. I have an AT&T-branded unlocked S9 (SM-G960U) and I have not been receiving software updates. The date of the installed security patch is Nov. 1, 2018, and I'm still on Android 8.0. When I check for updates, it says that my phone is up-to-date. My current carrier is outside the USA. I have also tried updating via Smart Switch but it also says my phone is up-to-date.
Is there any way I could get the Android Pie update?
Thanks for the help!

in short, the U1 is a debloated version of stock without the carrier junk. The different iterations will have different modem files that are intended to work best with the respective markets they are built for, globally speaking. Samsung stopped making a separate version for the GSM carriers in the USA with the S8 which is why all the stock image files are now cross compatible. They technically always were, its just that theyre far more interchangable now due to this physical difference no longer existing

So do you mean that the different carrier versions of U1 firmware don't have carrier apps, but have files that make the phone more compatible with the carrier's network?
It seems as though AT&T can only send updates over their network, which I don't have access to because I'm outside the US. If I change my firmware to U1, would I then receive updates OTA in the future directly from Samsung?

they have very minimal bloatware, they might include carrier apps, but very few. They usually have carrier specific radio firmware to allow the phone to operate best on that specific network, yes.
i would flash one in the very near future myself, but im about to head to Mexico on vacation, so im a tad paranoid to do so. Ill do it when i get back tho. By the end of this month, ill be running a U1 firmware set

Please read this, there might be some restrictions still applied to your phone.
Unlock app requires a TMobile account at least.
Tired waiting for sprint to send android 10 update.
lame carrier locked.
Use the Frija tool and download the Sprint variant of Android 10.

AFAIK you should still receive OTA updates

Thank you very much, however I am on a locked device and it's a miracle you found a sprint variant even though none reporting they got it on sprint. And the csc says unknown.
I am not ungrateful. I am afraid to flash via odin unlocked variant.
I have firmware N975USQU2BSL7 already of locked devices in the USA but the SPRINT USER DATA MD5 file,. and my query was if i install what I have, when january's patch comes will it update if im on december now. I would not yet try unlocked firmware and thank you for All you provided.

It will still work. The SPR in the ROM stands for Sprint. Check the CSC file to confirm before you flash it but I thought it said SPR. Just flash the ROM using the Odin patched version for it to work.
I am using a AT&T Note 10 with the Star Wars ROM and I just received the Android 10 update earlier tonight. You will still receive the OTA updates but they just might be for the unlocked version if you are okay with that.

IF I flash again, without the usual included spr user data will my locked sprint still get OTA for jan and forward.

For it to get the updates you need to use the CSC that came with the ROM you flash if that makes sense.

I have a question for anyone that may know more than me...
I have an unlocked sprint note 10 plus. Ive flashed it with XAA. So im on unlocked firmware on an unlocked sprint note 10. Im settings my csc shows this... tmk/tmk/spr. Im using metro pcs as the carrier. Where will my updates come from? Using sam info app, it shows the firmware as XAA and active csc as tmk. I have a bunch of avalible csc to use but i dont have the dialer codes with metro. I have inserted a att sim and i have the dialer code to change the csc. However when i put the metro pcs sim in, it goes back to tmk/tmk/spr.
Question 1: With tmk/tmk/spr, on XAA firmware, where will updates come from? Metro Pcs, sprint, or samsung?
Question 2: Are the csc codes tmk/tmk/spr correct being as i am on XAA firmware?
Thanks!
Have a carrier unlocked ATT device, and want to flash unlocked firmware.
Can someone explain in detail the steps to do this?

I'M NOT RESPONSIBLE FOR ANY DAMAGE CAUSED TO YOU DEVICE!
THIS IS THE PATH I TOOK.
I'll pass on to you what I did. I flashed over SPR unlocked.
1. Download frija, you can Google this. It's a neat tool to quickly download firmware.
Type in the model number of your phone, and add a 1 at the end... Example... I own the N975U, from Sprint. Add the 1 at the end for unlocked... N975U1. And in the CSC slot, type XAA.
XAA is unlocked CSC code for US.
Firmware should show last digits BSLD for January security patch and Android 10.
Unzip the downloaded firmware somewhere close. I did mine on the desktop.
2. Download Samsung Drivers and install.
3. Download Odin V3 V 3.13.1_3B Patched.
Add the files into Odin.
On the CSC, do NOT use Home CSC. Use the regular.
You absolutely have to factory reset your device when switching to Unlocked or vice versa. So you might want to backup using Samsung smart switch or Google. Which ever you prefer.
Do not add any user data when switching from carrier to unlocked.
4. Place phone into Download mode BEFOR plugging into computer.
5. At this point... Phone should be in download mode. 4 files should be added into Odin. No other changes in Odin should be made. And CSC should be regular and not Home CSC.
6. Plug phone into computer and see if you see the device in Odin.
If you see it, great. Proceed to flash.
Odin likes to verify for awhile so don't mind this. Leave it be. If it gets stuck more than 10 minutes saying verifying, you may need to Google the issue.
Once Odin says passed... You should be good to go.
Phone will reboot, phone will factory reset.
At this point, you should be done.

You mention the CSC should be XAA, when it comes to ODIN you mention regular?
Can you clarify that part?

In addition, do I have to backup the contents (no user data on it currently)?

It's two different things that's being referred too. When you download the firmware there isn't just one and they are identified by CSC. TMB is for T-Mobile, CHA is Spectrum Mobile, SPR is Sprint.. to name a few.
In your particular case when you download the unlocked firmware you would search for the CSC "XAA" (without quotes) as this is the firmware from the unlocked note 10+
Second when you flash the firmware you need to place different files into the appropriate and applicable locations within Odin. One of those spots you place a file into is called "CSC".
Also no you don't need to backup anything if you don't have anything installed (or no userdata on it).
If you have further questions I would suggest you search this forum and/or Google. The question on flashing the N975U1 firmware onto the N975U has been asked before and covered in detail already more then once... So those other threads will be of help for you.
Hi all. I am from Singapore and I have gotten a s22 off an online platform here only to discover it is a USA set.
The csc is S901UOYN2AVE4
I am unable to get ota updates and am still stuck with a may 2022 android 12 update while checking updates shows as up to date.
I have some questions after doing a Google search.
1) will I be able to get ota updates? Does this mean I have to somehow change to csc and is this possible?
2) if it is not, do I have to update manually thru Odin patched? Given the above csc, can anyone guide me as to which firmware can I use? I see there are many different ones from different carriers like Verizon or t mobile
Thanks in advance!
were you able to find a solution? I am also facing the same issue
None so far.
Have you guys tried smartswitch?
hello! I have also researched a bit & came to this conclusion. The device was possibly under a carrier (such as ATT or Verizon) from the US. Although it's unlocked and you can use any sim card but you won't receive any updates unless you use the sim card of that particular carrier. You can install the latest firmware using ODIN tool yourself by downloading firmware based on CSC region code. You can youtube to find the specific CSC region of your phone. Please let me know if you find any other solution. & also please let me know what 'service provider software version' is on your device. you can find it at About phone>Software Information

I have managed to flash it with the right software and get it to update ota. To test this I flashed a older android 12 firmware and it manages to update to android 13 ota.
Follow the steps in this thread closely and you will be good. Use the unlocked u1 version firmware.
https://www.reddit.com/r/GalaxyS22/comments/t49c10
Just to confirm one thing, My CSC is S901UOYN2AVE4 and AP/CP/BASEBAND is S901USQU2AVE4. Csc is basically same as you.
But my service provider software version is SAOMC_SM_S901U_OYN_GCF_12_0002
GCF/GCF, GCF/XAA.
Will it alright to flash u1 unlocked firmware to the device? This software version shouldn't be an issue right?
