For those who aren't already aware, G975U is the model number of all of the US carrier versions of the S10+. The G975U1 is the model number of the same device, but sold by Samsung SIM unlocked and with no carrier bloatware. Firmware is 100% interchangeable among these models: any U or U1 firmware version can be flashed to any U or U1 device at any time, assuming that you're not trying to downgrade the bootloader. A "U to U" or "U1 to U1" flash does not require a factory reset, but changing from one firmware to the other will require one. Also, U firmware is identical for the 4 base files (AP, BL, CP, CSC) for each individual build, no matter which carrier it comes from. So if you download 2 different carrier versions of the exact same build, the 4 base files will be identical. Where the firmware differs is in the USERDATA file - that's where the carrier bloatware and customizations reside.
Manual Odin flashing is designed for those who:
- want to manually update to a newer version of U firmware on their U device, either because they don't want to wait for their carrier's OTA or because OTAs aren't working on their device, or a different carrier got a new feature/patch before they did
- want to flash U1 firmware to their U device
- want to convert from U1 firmware to carrier U firmware
- want to convert from one carrier's U firmware (with all apps and bloatware) to a different carrier's U firmware (with all apps and bloatware)
For those who aren't already aware, anyone can now download firmware for almost any Samsung device any time that they want, via the various firmware download tools posted here on XDA like SamFirm or Frija. There are threads and info about them here on XDA so I won't waste time explaining - do a search if you're not already familiar with these tools. But they only provide whatever the latest/newest/current version is - nothing older. I pay for a subscription to a site that gets the official releases (usually) before they hit the firmware download tools, so that's where my files come from.
This is not a "beginner's guide to Odin flashing" -type post/thread, so I won't list basic, step-by-step flashing instructions. My threads are geared towards those who already know what they're doing. If you're new to manually flashing Samsung firmware (or haven't done it in a long time), I recommend you consult one of those "beginner's" guides- there are tons of them here on XDA.
Happy flashing!
U firmware: https://www.androidfilehost.com/?w=files&flid=290649
U1 firmware: https://www.androidfilehost.com/?w=files&flid=290650
Notes:
- I compress extra small for space and bandwith savings. The default Windows extractor can't handle it, so you'll need a 3rd party tool like 7zip, WinRAR, etc
- I remove the .md5 from each file solely for faster flashing (Odin won't check the file integrity without it). Rest assured, the files are perfectly fine and safe - Odin has a million safechecks built in.
- My naming method for folders is: build - bootloader - Android version
So "SAT - 1 - 9.0" means the full build number ends in SAT, it's bootloader version 1, and it's Android 9.0. When bootloader and Android versions increment, the first build to have those changes will have its folder notated appropriately.
- HOME CSC file keeps data intact; using the other CSC will wipe data. Any zips with "wipe" in the title do not have a HOME CSC included.
- I have identical threads for the S10e and S10 as well
- the correct procedure for switching from one carrier's firmware to another is given in post #25
- You can get USERDATAs from SamFirm for everything but AT&T and Cricket- those files will never be on SamFirm. So in addition to the 5 piece firmware, I'll try to always upload one USERDATA per bootloader increment for those carriers.
- For identifying USERDATAS, and to know what region/CSC to use in the firmware download tools if you're downloading yourself:
AIO = Cricket (not available via firmware download tools)
ATT = AT&T (not available via firmware download tools)
BST = Boost Mobile
CCT = Xfinity Mobile (Comcast)
CHA = Spectrum Mobile (Charter)
SPR = Sprint
TMB = T-Mobile
TMK = Metro PCS
USC = US Cellular
VZW = Verizon
XAA = U1 firmware
This is looking great, was about to pre-order the T Mobile variant, when I remembered that they disable the (Data) Quick Toggle and I have to fiddle around to turn it off, Well, Not the case with the Unlocked version, at least on my Note 9. Anyways, this will come in handy, thanks!

Hopefully One UI stays the same. You're welcome
Good to see and will be a good place to hangout! ?
Loved your dedication to uploads on the 9+! Glad to see you here as well! I preodered my ATT 10+ yesterday. Got my mom and two daughters the 10+ / 10e also. Happy to see you'll be providing firmware for the "E" also!
Build SBA added.
Only CCT, VZW, and SPR USERDTAs (for now), but it can be flashed to any S10+
So I flashed this on my new U1 and went to U firmware. My Wifi didn't work after this. I can't connect to any Wifi network... I will try going back to U1 and see if the issue is fixed. Maybe I have a defective phone?

Hmmm that's weird. I'm assuming you wiped?
G975U and G975U1 firmware is now live and downloadable in SamFirm. Getting U1 requires manual entry - Auto will not work. U firmware is up for these carriers:
Xfinity Mobile
Spectrum Mobile
Sprint
T-Mobile
US Cellular
Verizon (have to use Manual entry - Auto will not work)
So going forward, I'll only be adding full builds if I can get them before they hit SamFirm, and only if there isn't build for that month already (eg. I won't add any more February builds since SBA is already up.). I will try to stay up to date on USERDATAs for AT&T and Cricket, since AT&T won't let their firmware be put on SamFirm.
Thank you for this. Just flashed my U1 to TMB SBA for video calling feature.

I have a question and I hope someone can help me. I just purchased a s10 not the plus. And its unlocked which is great but has three UK branding on boot up ect..,
Is it possible to remove this maybe install another rom via oden? And it wouldn't void warranty or enable a security problem on the phone? Any help would be much appreciated
Guessing ATT is late to the party as usual with no ASAB userdata yet? Doesn't appear they've pushed it yet ?

Anyone can flash any update - USERDATA isn't required unless you're changing from U1 to U, or from one carrier to another.

Ah ok. On my S9+ I did some Odin flashing and even though I was on the att release, I wasn't getting OTA's. It was odd. Only way to restore OTA updates was flashing with ATT userdata.
On a side note, ATT has pushed the ASAB update for both the S10+ and the S10E.
One of our Chineese suppliers has gifted me a New Fold 3. The issue is the stock Chinese Rom, or rather the restrictions that come with it (nerfing most google based services, and apps i use all the time.). The device is great but restrictions applied give you a feeling of a second class android user, with core sevices absent: Play store, youtube, gmail, maps, chrome, android auto., can't even apporve family link download requests from kids. etc. etc.
I have made the choice i would rather go back to my S21 if i can't resovle this issue, as phone is useless like this.
Advice required on Loading Australian Rom via odin.
The phone model is: SM-F9260 which only seems to have overseas Rom available for download. Can i successfully load a ROM made for model SM-F926B (Australian) on a SM-F9260?
All the how to guides specifically say jou must select the same model number, and i don't want a brick it. Will have mud on my face next time i see the supplier if i have bricked their gift to me.
Any feedback/advice from users with more experience with odin and flashing would be appreciated.
Both are on Snapdragon CPU so shouldn't be any problem to flash it with PIT over the Odin.
But I never done it so I can't give you 100% answer.

Update: The AU version gave me an Auth Failed in Odin. Chances i could have resovled by unlocking the Bootloader which i didn't want to risk tripping the e-fuse. I ended up just using the Taiwan version which had the identical model number, and falls in the same region as China. Odin flashed without complaint. The taiwan version has no restrictions on google services, and once you set the language its hard to tell it from a regular AU one; unless you know what you are looking for that is.

Technically there are ways, just it is very grey as to when/how you trip the e-fuse. Some say if you simply unlock the bootloader and restart, others say when you load a bootloader that doesn't match model numbers, or is older than your current, or isn't offical samsung one. I personally don't know exactly. I do however know that i didn't trip the e-fuse when i loaded the taiwan version, and i didn't have to unlock the bootloader in developer options to achevie this.

you won't have the chance to trip. there is some check before the boot image is integrated. so it failed showing some error, auth or secure check failed etc etc.
if you flash variant home csc you will trip
TBH, I consider the Chinese version is the best version above all other region. The dual sim is enable on Chinese version, 512GB is the only available option.
As for google service. You don't need to change the Chinese firmware to Australian to enable it, the GMS is pre-installed. All you need to do is to find a way to install the google series apps as apk by yourself, it would work just fine.

BTW, the only version that Chinese region Fold 3 can change is the HongKong firmware, all other regions are not available. If you use Chinese region Fold 3 in Australia, the only thing you need to concern is the Samsung Pay, but Samsung Pay is fixed by the region and cannot be changed by switching the regional firmware.

Each to their own, if you like the chinese version great. I hated it, restrictions in every aspect of the firmware. I personally am unsure how you rate the chinese version better, when it is loaded with restrictions and hard coded settings that can't be changed, or if they can it is really a sub par workaround. Settings that are not present in standard android builds. What exactly does it have extra that makes it better? If you like it thou that is all that matters.
I loaded the taiwan version which yes is really just the hong kong version. No restrictions, no issues. Now it works just like any other standard samsung android build, you get in AU. Yes samsung pay that use the firmware version doesn't work great, but i prefer google pay anyway. No need to stuff around with downloading apk files from third party sites, for core functions. No need to even enable developer tools.
The chinese version sounds like driving a ferrari on a go karting track.....
Can you flash the Chinese or any international dual sim version to work in the US ?
Hello is there any free way to debrand Samsung A52s on Android 12 One UI 4.0? I also dont want to trigger the KNOX flag. My current CSC is PRT (Poland (Play)) and I want to make it XEO (Poland). I already tried some methods with phone call codes and none of them work. Is there any way to do this?
If by debranding you mean removing bloatware and changing your bootanimation etc, just root your phone and do those things. You'll easily be able to find tutorials on how to do all that for your device.
Now, if by debranding you mean that you want a stock android feel, then sorry but your device doesn't have any custom Android development, so you can't install a stock/custom ROM.

By debranding I mean get full stock Samsung firmware which CSC code is XEO, and my current CSC code (PRT) and both are in OXM - multi-CSC so I need to change the CSC code, but tools that can do that are paid, like SamKey so is there any free way
I don't have much experience with oneui Samsung devices, so I've got no idea, sorry.

There is nothing about how to do it just link to ADB
Then there's probably no free way to do what you're trying to do. Also in that post the person claims to have the same csc code as you (prt), and samkey did not work for him.
@Raflen100 Hello! Have the same problem as you: purchased a carier SM-A528 whitout realising the consequences and am no bugged by the super slow updates. I think i am on the same OXM firmware as you. Want from DTM to DBT. My attempt to simply flash DBT and then use dialer codes to switch the CSC failed all.
SAMkey is no option for me, as i don't have any idea about the background and don't want to ;-).
Also: don't want to trigger KNOX.
Since i use a different carrier, i just want a stock SAMSUNG and don't have to wait for weeks for my updates.
If you found a way in the meantime, that would be good news.

Actually, there is a way that was created in the meantime. Around may 2022, developers of samfw.com created the SamFw Tool. It can change the csc of phone through ADB without root, so it does not trip KNOX or wipe data, which is awesome. It worked for me really well. Just make sure to use the non-root CSC change.

Hello @Raflen100, thank you very much. That looks actually very interesting. I currently seem to be not able to find a version without malware, but i'll keep it on my watch list. Can you accidentally tell from experience, that the [provider] CSC change work without need for rooting? My impression so far is that the provider CSC can not be overwritten by flashing, even after having removed the filesystem, so may be stored somewhere else? Or is the SAMSUNG server telling it to the phone, based on it's IMEI?

You can download it from the link I gave you, it's the official post so no malware.
Yes, it does not have any need for rooting your phone.
Answer to your question is very simple, samsung has multi-CSC roms, so flashing one or another won't change anything on the newer phones. There still are single CSC roms, but there are really few of them. And yes, I think it's based on IMEI, because you can't change the entry for the factory CSC, it will always remain there, but you can change the current CSC of the software just by using this tool.

Hi, i have verizon galaxy fold 3 (unlocked), can i change phone firmware? i dont want verizon bloatware and built in apps
i want to make it like normal unlocked phone without carrier things
and if it is posible can you link best firmware for it (with esim support) and some tutorial how to do that
thanks
As the title suggests, I was able to successfully change the CSC on my factory unlocked (unbranded) Fold 3 - F926B/DS bought in Germany with OXM firmware having Android 13 & one UI 5.0 from EUX to INU csc using SamFW Tool v3.31 in hardly 2-3 mins. Kindly note that I also looked into other options to do this like Samkey tool (paid service) and alliance shield app (which doesn't work anymore) etc before engaging with the SamFW Tool as none were simple/working with no complications whatsoever involved.
My main objective to change the CSC was to enable call recording and couple of other features (including some pleasant surprises listed in the end of the post) which were available in the INU csc with little to no hassle. The process was pretty simple, straight forward and most importantly, FREE . It DOESN'T require any factory reset, flashing of roms or wiping cache partition before or after the process.
The step by step guide process which worked for me is as follows:
STEP 1: Click here - SamFW Tool Download - to download the latest version of SamFW tool.
STEP 2: Remove the sim card and connect your phone to a computer and make sure the phone's drivers are installed.
STEP 3: Unzip the downloaded file. Right click on the file SamFwFRPTool.exe and 'Run as Administrator'.
STEP 4: After the software opens, make sure your phone is detected before proceeding. If its detected, click on ADB tab in the software.
STEP 5: In your phone, go to developer options and enable 'usb debugging'.
STEP 6: In your phone, open phone dialer and type *#0*# to get into test mode. Leave the phone unlocked and keep it aside now.
STEP 7: Click on 'Change CSC' button in the ADB tab of the tool. Now the tool will connect to your phone, check and list the available CSCs which your phone model supports as shown in the pic attached.
STEP 8: Choose a CSC which you wish to change to from the drop down menu in the pop-up window as shown in the pic attached.
NOTE: The tool also has the option to force the phone to accept a CSC not listed/supported as well by manually entering the same. However, I would not recommend doing it if you really wish to get OTA updates and also to evade any unforeseen issues. I must admit, I haven't frankly tried this and do not know what lies in the pandora box to be honest.
STEP 9: After choosing the CSC from the drop down, the tool quickly connects to the phone, changes the CSC and restarts the phone.
STEP 10: After the phone restarts, unlock the phone using your pin/password, insert your simcard, check the change of CSC in software information, disconnect the phone from the computer and also disable the 'usb debugging' in the developer options.
That's it! All done. Phone restarts with the new chosen CSC and the related features will now be active!
BONUS: There is also an option in the ADB tab in the SamFW Tool named 'Battery information' which gives the complete information of the battery status including the 'charge/discharge cycles' along with its temperature, voltage etc. like in the pic attached. Do note that the information shown in the 'Genuine battery' section isn't correct for some reason and always shows as 'NO' for any phone with/without genuine battery.
With my choice of INU csc the following major changes/surprises were noticed over the EUX:
1. Call recording and a couple of other INU specific features are now enabled (google for more info on what csc enables what features).
2. Not sure why but Battery backup has increased significantly after the csc change to INU. SOT (Screen On Time) which has fallen to 3-4 hrs after the OTA update to One Ui 5.0 & Android 13 is now back to 5-7hrs or more.
3. RAM management has definitely got better. With EUX csc it used be around 5-6GB during standby and now its always around 3-4GB when the phone is idle.
4. Instead of 4G or 4G+, now it shows LTE and LTE+.
5. Mobile data speed has increased both in 5G (Jio True5G network) and in LTE+ when compared to EUX CSC.
6. 5G signal strength has improved drastically. Signal loss or switching to 4G+/LTE+ is very low now.
7. 5G to 4G/LTE switching while calls (VoLTE/VoNR) is more seamless now. Latching back onto 5G network after a call is a breeze now unlike earlier with EUX csc.
8. Phone definitely got faster for some reason. Can very much feel the difference when switching between apps, multi-tasking, even opening/closing apps and other day-to-day tasks.
etc...
Haven't tested whether the OTA updates will still get pushed after the change in CSC yet, as my phone is already updated to the latest patch as I write this. Should absolutely work IMO as long as we choose a CSC which the phone supports but in any case will update the thread once the next update via OTA is available/pushed by Samsung.
Disclaimer: Please be informed that all the above information is purely based on experience of using the tool for changing CSC only which worked well for me with my Fold 3. Cannot take responsibility if it doesn't work for you.
Does it work for Fold 4. Want to change CSC from Korean Region to INU (India). Please guide
Sorry, haven't tried it on Fold 4. Logically it shud work, I guess. There is no harm in connecting n checking what CSCs does ur model supports using the tool IMO.
Tried out but it does not work. It shows only the Korean csc. Even that seems to be not changing
Oh k. I think the tool works, else u wudnt b seeing the CSC which ur phone supports.
I have checked sources in the web as well on this and looks like Fold 3 or 4 with Korean CSC supports only CSC from Korea.
I guess u can still force a CSC on to it replacing the Korean one but thats too risky as u will b missing OTA updates and im not aure wat all things it will mess up.
Awesome! It works and it doesn't wipe the device. I just switched from G975U VZW to CCT without any issues.

Happy to hear that. BTW I also got samsung pay/wallet to work as well by installing its apk file today after changing the system language to a local one specific to the changed CSC i.e., English (India) for INU CSC in my case.
I confirm that it is working on a stock android 13! Great tool!
(It worked on the second try though )
Has anyone tired it on a Fold 4, Mine is XAA and I want to convert it to INU. Haven't been abe to do it as yet.
Let me know if someone finds a way, mine is a US version and I want to convert it to the India CSU.
Thanks in advance

Oh great. Getting otas after the change?
Does OTA work after change?
Hello, can somebody please briefly summerise the options for switching the CSC/Firmware?
I read other threads and this one and now am confused which method actually would work for me.
My situation: i have a Samsung A52s 5G purchased from Deutsche Telekom in Germany, sold separately, not bundled with a contract.
And i am having a contract with a different carrier on a different network, but a german SIM card.
My phone is configured all english, and i need to keep that.
Because of assumed network optimisations and the problem of delayed updates of "branded" phones, i would like to convert the phone from the current CSC of DTM to the DBT using fimrware (A528BXXS1DVL2/A528BOXM1DVK5/A528BXXU1DVK5/A528BXXS1DVL2), which i hope would link me to updates directly provided by Samsung.
I found "https://forum.xda-developers.com/t/...official-firmware-all-samsung-device.2697238/" and "https://forum.xda-developers.com/t/...-multi-csc-codes.4436853/page-5#post-87485577 ", but i am not sure whther the methods described there only apply for UPDATING (within the same CSC) the phone with non-OTA methods, or whether that also covers SWITCHING the CSC?
In the end i have two questions:
1) So far i believed that "simply" putting an official stock Samsung firmware (multi CSC in my case, containing the DBT, but apparently NOT containing the DTM) would bring me there.
But then i read that this might not be suffficient. Instead i also would have to switch the CSC in my Phone's config, which apparently would require purchasing a license for a Samkey unlock code.
Because otherwise i would not receive any OTA updates once i switched just the firmware.
Is that actually true?
I would prefer not to have to buy a Samkey...
And to make the confusion even bigger: now i read, SamFw Tool would also be an option?
But: is that trustworthy? And: from posts of some of you: this might even obsolete to switch the firmware, do i understand that right?
2) If switching firmware still is required: would using Odin/Heimdall be the only option to switch the firmware, or would adb sideloading do the same job as well? I am asking because i don't have access to a windows machine.
Would be so great if someone of you could untangle my confusion a bit, thank you.

Did not automatically receive the OTA updates with the recent DVL9 update. However, tried a work around to change the CSC back to EUX via the same tool (which is a 2 min task) to check if I can get OTA again.
And yes it worked! immediately after changing the OTA to its home CSC, was able to see OTA in the updates section of the phone. So, I updated the phone to the latest version (DVL9) and then changed the CSC back to INU after the update . All is well and quick! .

May be TUR csc has restricted options/features. In my example after I changed to INU csc (India one) all the India related options got automatically activated like call recording, spam filter, samsung pay using cards etc etc. which weren't available with the EUX csc before the change.

Any potential issues using INU csc in the UK? I use Samsung pay already but native call recoding would be really useful for me

Might be worth clearing cache and data from Google play services see if that helps. Having the same device with 2 different cscs might have confused Google
Edit
Any reason your Google play store is out of date or is it connected to your original issue
