I just got a galaxy s10+ from a friend who was on Tmoblie so it has the Tmoblie loading screen and apps. I would like to revert it back to the firmware CSC code XAA so I dont have to have the Tmoblie boot screen and apps. He didn't buy it from tmoblie its from an insurance company so I am pretty sure its unlocked. The app "Phone Info" says that Firmware's CSC code is XAA and the active one is TMB. I have tried to put in the *#272*IMEI# code into the phone but it just gives me an error code.
Is there anyway to revert it back to XAA without flashing the phone? Will I void the warranty if i flash the phone with official firmware? Also if I have to flash the phone where do I find XAA firmware as I only saw carrier firmware on SamMoblie.
Thanks for any help and very sorry if this has been posted a thousand times!
Also the phone model is SM-N975U / Galaxy Note10+
Device Type: d2q
Product Name: d2qsq
Bootloader Version: N975USQS6FUF1
CSC Version: N975UOYN6FUF1
Phone is on Android 11
I just flashed the phone and it all worked out. I used these threads to figure out the solution if anyone else is ever interested in how I solved this problem.
Note 10+ N975U carrier universal and unlocked models firmware.
Yep. I'm going to download the files just in case ,but wait a few days to see if anything happens.I'm curious if that was your issue all this time .

Odin Files/Guides For S21
Flashing S21 Ultra t-mobile branded to unlocked? Hi Everyone, I am a new samsung owner. I recently got s21 ultra t-mobile branded. It is now network unlocked. But i wanted to have a clean bloat free phone so wanted to have unlocked firmware. As i understand it, i need XAA G998-UA firmware...
forums.androidcentral.com
And I used this very kind user on Androidcentrals help. The context of my question is not needed but I basically asked if I was choosing the correct files.
"Yes use the firmware from frija , you will also need prince comsey patched Odin which download from XDA website, this will factory reset your device for first time , choose XAA as region with model number from unlocked version. (He is refering to the model number SM-N975U1) Put the device in download mode and make sure using a good cable and try 7zip to extract the firmware,odin,frija ...then after extract the the firmware you going take for files Cp/CSC,Bl,Ap and put in corresponding slots in odin and flash"

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.
I'M NOT RESPONSIBLE FOR ANY DAMAGE CAUSED TO YOU DEVICE!
THIS IS THE PATH I TOOK.
You mention the CSC should be XAA, when it comes to ODIN you mention regular?
Can you clarify that part?

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 guys I got a Verizon N975U note 10 plus and its stuck on Verizon I'm trying to flash it with U1 so I can pop a sim in and changes it to that carrier. Do I just need to flash it with the U1 file here https://androidfilehost.com/?w=files&flid=297980 or will it need something special the build # is SQS2ASJ8

Can't say for sure it would work on U firmware (lack of first hand experience to verify) as it would for U1.... As long as the phone is network/sim unlocked then you should be able to just put the new sim card in it (and the phone will read the sim card settings and apply them).
Flashing the U1 firmware instructions on flashing U1 firmware have been at link below (bottom of first post). You can get the firmware from that thread also.
https://forum.xda-developers.com/showpost.php?p=80072192&postcount=1
Of course keep in mind that none of this will matter unless the phone is sim/network unlocked. As long as you meet the requirements from Verizon (or the phone was blacklisted for either non payment, lost/stolen or a warranty/insurance exchange that wasn't sent in) then this shouldn't be an issue.
its locked to Verizon at the moment when I put a sim in it will work for a bit then say its not allowed to use another carriers sim at this time.

Either wait until the phone is able to be unlocked by Verizon, or call them and request that they unlock it for you. Until that happens you will not be able to use a non-verizon sim card.
I would also advise keeping the U firmware for Verizon installed and not flashing the U1 firmware, as the Verizon sim/network unlock requires the carrier firmware... At least that is what I am gathering from various discussions/threads.

Is your phone carrier locked to Verizon? Has it been activated on Verizon's service for 30 days? If not, I'm pretty sure firmware flashing won't help anything. I'm on a Verizon MVNO and they wouldn't even unlock it for me to use on their own network. I had to activate with them for 30 days.
However, now that mine is unlocked, it's still locked down to Verizon in a lotof ways. My SIM card for my current carrier can't apply an APN, for example, so I have to do it manually. I'm contemplating flashing U1 to fix that issue (I hope).
I have a very similar situation. I bought a Note 10+ N975U (Verizon Unlocked) and I want to take it to U1 and then maybe to Sprint. I tried to go to the OP here and follow instructions. So I downloaded and selected all the files for U1 and apparently I did the "no-no" and got stopped with the SW Rev Check Fail : abl Fused 2 > Binary 1. I looked at what my phone is on and it is the SJ8 (November?) from Verizon. I'm guessing that means the BL file (bootloader?) in the U1 folder (SGO?) is older than what is on my phone? What do I need to do differently? I already tried without selecting the BL file, but it still gives the same error. Any help is appreciated! Thanks in advance!

The bootloader of the U1 firmware you were trying to flash is lower then what is currently on your phone. So yes you are correct that is the no-no. Also you can not skip the bootloader file when flashing, so that wouldn't have worked.
If you read through that thread you will have found others asking how to go from U to U1 firmware. Also the error within regards to trying to flash a lower bootloader version firmware was also asked and answered. I would encourage you to browse that thread and the Q&A forum because this process has been discussed on more then one occasion... It might contain helpful/useful info for you.
In short you need to get a newer firmware release. Using samfirm or frija apps, or the sammobile website look for the firmware your seeking. Google searching will show you how to obtain samfirm, frija is posted the forum here if I recall correctly.
For U1 the model is SM-N975U1 and the region is XAA.
Hey all,
I am trying to flash the Tmo firmware onto my unlocked Ultra to get things like the video call option in the dialer, and for the life of me I am getting lost.
I used both Frija and SamFirm to downlad what it said was the correct firmware (SM-G988U1_1_20200312212815_gne8hvb170_fac.zip) putting TMB in the CSC. I flashed that firmware using Odin,
Here is what I did:
Downloaded the firmware (SM-G988U1_1_20200312212815_gne8hvb170_fac.zip) in Frija putting TMB in the CSC box
Unzipped all the files
Flashed them all to the phone in Odin, using HOME_CSC_OMC_OYM_G988U1OYM1ATCH_CL18186338_QB29814488_REV00_user_low_ship_MULTI_CERT.tar.md5 so as not to wipe my data
There is no error, and it finishes successfully, the phone reboots, and there is no change whatsoever.
Am I missing a step here guys?
Thanks so much.
**EDIT**
I finally figured it out.
I needed to flash the TMB U firmware, not the U1 firmware.
Curious do you notice better signal strength on TMO U firmware vs unlocked U1?
I feel like I've done a big door.
I work in a cell repair shop and we had an ATT unlocked S20 FE that came in and I liked it so I bought it.
Long story short. I did some reading that you can install the XAA software using patched Odin. This was essential because I'm on Tmobile and didnt get 5G on the ATT firmware.
Easy enough. The device now has 5G access on Tmobile, and identifies itself as SM-G781U1/DS in settings.
The issue I'm facing is now unlocking the bootloader. The XAA firmware doesn't have the option and I'm unable to flash back to ATT firmware without (auth) fail errors in Odin and 'Secure boot check fail: PIT' on download mode.
Here's what I've tried that's failed so far:
- show option using time/date change
- software updating (I do receive OTA)
- flashing stock ATT firmware
- flashing stock TMB firmware
- Fastboot oem unlock (command not found)
- fastboot getvar unlocked (unlocked: no)
I'm about out of ideas, could use some guidance on where to begin looking next, I really like the power of this phone and wanna see what custom roms bring.
Device stats:
Galaxy S20FE SM-G781U (with U1 XAA flash)
CSC: ATT
Build: G781U1UESAGWC7
Service provider info:
G781U1_OYM_TMB_13_0011
TMB/TMB/ATT
Android 13, One UI 5.1
To be honest the custom rom screne for this phone is not so great yet. I imagine once the official support ends we will be getting some well developed custom roms.
As for the bootloader unlock issue, try using smartswitch to restore stock firmware, or try changing only the CSC if the firmware is multi-csc, the oem unlock option might reapper.
What kind of patched odin did you use to flash the XAA firmware? stock odin should be able to flash it too. As far as i am aware north american samsung phones do not offer oem unlock. The option probably dissapeared for good. There was etoken but since you are on android 13 i imagine the exploits have been already patched. You're basically stuck on XAA now. You can try using samkey to change the csc but i doubt that even that can help you oem unlock it.

for some reason Samsung doesn't allow bootloader unlocks in the US anymore. if as a phone repair guy you have the means force older firmware onto the device then you could pay someone to get an unlock token on the DL from a contact of theirs.
downgrading isn't something we can do at all hence me mentioning you maybe having access to resources others don't.
if you could get it onto the very first firmware you'd have a chance, if you can't there's no chance.
I would appreciate if anyone can point me to the right direction. I have 21FE G990U2 from AT&T, It is unlocked by AT&T.
All I need is working T-Mobile firmware or Samsung (no carrier branding) to flash. I tried multiple versions of U, U1 and U3 firmwares (all matching my current Binary -4) but no success.
I just would like to get rid of ATT bloat. I know I can uninstall it via ADB but I rather have firmware clean of it.
Any suggestion please?
Thanks
So am I right to assume that you are looking for a G990U2 TMB firmware with Binary 4, to flash on a G990U2 AT&T phone?
If so, then you can download it from the below link by clicking on "Download Samfw server" (G990U2OYN4EWC3, April 2023 update):

or if I am assuming wrong, can you please correct my understanding? As I do not have any practical hands-on experience with the USA models.

You are correct - I need T-Mobile (or carrier free) so I can utilize full carrier settings.
Thanks for the link, however above link gives an error when opening the page.
Nevertheless I will look for TMB firmware with CSC: G990U2OYN4EWC3 and post an update here
Flashed that and still has AT&T boot logo and all the apps

Well, I am sure that you have flashed by a Factory reset (Flashed CSC, not Home CSC in ODIN). The boot logo can be changed by rooting your device, also bloatware apps can be deleted via ADB command without rooting.. but you already have mentioned that you prefer not to proceed with those processes. So I am out of suggestions, sorry.
Just for my knowledge, after flashing the TMB firmware, now your settings> About phone> software information> service provider software version: 2nd line shows as TMB/ TMB/ AT&T?
(Also corrected the download link in my previous comment anyway).
Yes, you are correct i did flash CSC, not home CSC. Then I reflashed w home CSC but software still says ATT/ATT/ATT.
Moreover on Bootloader screen says "carrier ATT" - I have never seen that before on any Samsung phone that I had. I have no clue how did they lock up device that well. As for removing software via ADB that is not a problem, but ATT locks network selection mode so you cant choose between 5G, LTE, 3G etc..
TMobile in US still supports EDGE and sometimes it comes handy - whereas ATT has only LTE and 5G as they re-farmed EDGE and 3G/HSPA frequencies

I do not get why the CSC can never be changed, even after flashing the complete firmware... must be an ATT thing!
Anyway, to change the csc only, there is another very quick & easy method. It takes only 2/3 minutes; no flash or factory reset is required. You have to download and install a small software "SamFW Tool" on your pc/laptop (may need to disable the antivirus during the download/install process). Once done, connect the phone and enable USB debugging mode. Open the software, under the ADB tab, click Change CSC, from the dropdown list select TMB and click Change. The phone will restart and CSC "Should" change to TMB/TMB/ATT.
Here is the download link for the software:

That did the trick. I have T-Mobile CSC now
Thanks a lot

Great!
But still, that's only one part of the final solution I think. Your target was to replace the complete firmware from ATT to TMB, right? Since the CSC is now changed to TMB, I think you can give it another try via ODIN to install the TMB firmware now (only if you want). I am not confident that it will work now, but still, one last try should not be much of a hassle.
I think that these multi CSC contain all US carrier customizations....When I changed it to TMB it shows TMB/TMB/ATT and loads bootlogo as well as TMobile apps... I guess it is similar as Blackberry used to be back in the days...Depending which carrier SIM used it loaded proper settings from the firmware...
