I bought an unlocked SM-T878U for AT&T and since the tablet for T-Mobil has the same model number for either provider, can I Flash the firmware for the T-Mobile Tab S7 onto my tablet without any problems? Sorry if this has been asked I searched around for over an hour and didn't find the info I wanted.
Edit: this is the 5G version not the LTE but both are 5G
Thanks
Yes... you can flash firmware from the same model.
T-Mobile and AT&T should be using the same firmware (T878USQU1BUAC).
Your SIM card and device CSC determines what carrier specific apps and features to load.
Thanks for the info mine is using a different version then the one you listed I just don't want to brick a tablet I just paid 500 for...

ATK1 is an older version. Just make sure whatever version you flash is for the same model number. T878U.
It will install without issue... make sure to flash HOME_CSC to keep all of your data, apps, and settings.
Thank you for the info and I didn't know that home CSC would keep all my data... Thank you.

You're welcome.
The rule applies to all Samsung firmware.
Flash CSC_OMC to do a clean install.
Flash Home_CSC to keep your stuff.
That did not work I downloaded the firmware and flashed it and now it just goes to recovery mode and won't even boot up anymore figures this would happen, just the way this year has been going, you have a place I could download a good firmware to just completely nuke it and go back to stock? It was stock before I mean I just tried to put the T-Mobile Version on.
From this site, https://galaxyfirmware.com/model/SM-T878U and I used this build number T878USQU1BUAC
Edit: Edit it did end up finally booting up after doing the app repair function in the recovery and also a factory data reset but still says AT&T only thing that has changed is I now have android 11 lol
I just want to get all the att stuff out so I can use the t-mobile texting and whatnot I can't use that now because of the att junk.
It is like a VIRUS infesting it.
Again thank you for all the help.

Looks like you'll have to manually change you CSC.
This post has some advice on how to get this done.
SM-T978U Odin Firmware Flash
Purchased a sim unlocked SM-T978U (Verizon Tab S7+ 5G) and am trying to flash the unlocked or Tmobile stock firmware to it. I've gotten "passed" flashes everything when flashing all of the files from the corresponding stock firmwares, but...
forum.xda-developers.com
Also make sure you are using a patched version of Odin when flashing packages... I assumed you know that, but in case not, here is a link to download it... https://www.androidfilehost.com/?fid=1322778262903995077
From all the digging I did. It is not possible as you have to unlock the bootloader to change the CSC. And well I spent over 3 days on this crap to no avail. I just sold my ATT model and bought the tmobile version. So ridiculous that Samsung does not just sell an unlocked version to avoid this hassle. Very annoying.

How can this be?
I bought a S6 Edge which was originally on the three (UK) network. My carrier is Vodafone, so I want their build on my device to access carrier specific features such as wi-fi calling.
Simple right?
Download latest Vodafone UK firmware (G925FXXU2POHC), load up Odin and flash you would have thought. Side step the hidden.img Odin fail by reflashing hidden.img once the original flash has failed. Reboot into data wipe menu and clear cache and other data etc, reboot and job is a good 'un.
But no.
When I restart the phone, no matter how many times i've tried - the device proceeds to install Three (UK) branded bloatware; these are the Three likes, Three In Touch and a couple of other Three branded apps.
How can this be?
Is there a way I can reflash the device to give me an exclusive UK Vodafone rom experience? Whilst the three bloatware is removable manually, this should not be happening and I'd prefer to have the vanilla vodafone experience. Any ideas?

In hidden.img and cache.img are those files that "customizes" your phone the way that carrier wants. So if you can't flash them, then it is not a very easy thing to do
Managed to sort it by reflashing with a PIT so i'm on latest voda which is multi CSC.
Only problem with this is that the CSC choice has defaulted to Slovenia, when it needs to be VOD for the UK. Anybody know how to change this? Seems with a multi-CSC stock rom without rooting you just have to take what you're given.
I would like to access the wifi calling features from Vodafone so guessing i'll need the correct CSC to achieve this.
PIT FILE
Could you please tell me which pit file you used? I too want to use vodafone wifi calling but had a European device. Just like you I got the good old Slovenia CSC, had to root the phone then became a simple as using Samsung Phone Info to change the CSC so now I have VOD as my CSC but still have no wifi calling option which I believe should be there in their latest release ..... But cannot be used as it needs activating at account level and they are still beta testing it with some users .... I missed out on the testing as my phone was not branded

Sure i went for the 200mb PIT which was enough to flash the vodafone stock. You can find it here http://forum.xda-developers.com/galaxy-s6-edge/general/g925-pit-files-multi-thread-download-t3171636
Did rooting the device trip the Knox or do you anticipate any warranty issues doing so? Sounds like there is no other option to obtain the UK CSC
It did trip Knox so I just hope Samsung phones live up to their reputation for being sturdy. Thanks for the info, will flash the pit at the weekend
Hi,
This is one of my first posts so please bare with me. You will need to download a few programs to get this working.
The first is frija. LINK - https://forum.xda-developers.com/attachment.php?attachmentid=4886005&d=1574653611
Above app is not mine all credit to the dev in the link.
Secondly you will need Odin I'm sure you can all source this yourselves.
After downloading and installing frija, open the programme and search for SM-N970F CSC code DBT
Continue to download the firmware and then flash with odin.
Simple method if you cant wait for it to be rolled out in your country.
I am not responsible for your data or devices, follow the steps at your own risk.
This should work for note 10 plus also, just change the model number and keep the csc as DBT
can i keep home csc ?
Not Sure

I did a clean install, in odin i selected wipe in options so formatted all and it installed perfectly. Perhaps use smart switch to backup all your data and then flash if you still have this option available to you.

What model phone are you using and what network CSC are you going from and to? I went from UK unlocked direct Samsung handset BTU to Germany DBT model SM-N970F. Worked without issue. If you give more details maybe myself or someone else will have the answer.
Odin files version 3.13

Hello
I have an unlocked S9 + US from the operator Sprint:
model's number: SM-G965U
Version : G965USQU3ARG2
oeprator soft ver: SAOMC_SM-G95U_OYN_SPR_00_0089
36514b5658543098
SPR/XAA/SPR
unlocked with them : https://store.unlockboot.com/unlock-samsung-phone/
It works perfectly with my french SIM but I want to flash it with an official samsung US rom to eliminate all traces of the sprint rom, could I still use my French and Algerian SIM please? Any risk with a standard flash? Where can I find the stock rom?

dont flash a USA carrier firmware set for it (theyre not ROMs when you flash them in Odin, theyre called firmware). Flash the firmware with a multi CSC, preferably one that contains your needed CSC

that error wont cause any issues other than just plain being super annoying. Each USA carrier has something stupid built into their firmware that causes silly headaches like this. If you get a notif in the pulldown area, you should be able to long press on it and tell android to ignore it. If not, you might just need to find the U1 version of android 10 and flash that on your phone so it doesnt know its a sprint phone anymore. Phone amnesia for lack of a better way to describe it LoL
THX very much but I dont where I can find this U1 version of android 10 for s9+? Last question can I install a french firmware version?

you can install a French version if you like, but the U1 version is the unbranded version and you can just pick whatever language you want upon install. Honestly, i would just flash this https://www.sammobile.com/samsung/g...SM-G965U1/XAS/download/G965U1UEU7DTA5/314795/ by using patched Odin which can be found here https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
THX very after installation I insert my simcard. I have a message like my phone import info from sim card and now no message error and the CSC is XAA, no sign about SPR.
it seems good.
Hi, I have an S21 and it is now bricked. I get the 'super build-id does not match with the reference' screen, every boot. I can get it into Download mode and it does show up with a com port in Odin. It is an unlocked phone bought directly from Samsung with a VZW sim card put in it. It was running G991U1UEU5CVDC (see attached screen shot of exactly what was running before bricked) and I want to put the same build back on it (or any build that will do the trick) with Odin to be able to get my Pictures off of it. From Sammobile I can get G991U1UEU5CVDC (https://www.sammobile.com/samsung/galaxy-s21/firmware/SM-G991U1/XAA/download/G991U1UEU5CVDC/1641071/)
Questions:
1. Do I get the XAA or the VZW firmware? (I assume XAA but not sure)
2. Both the XAA and VZW G991U1UEU5CVDC have the date of Apr 22, 2022 that matches my phone but the firmware times are 00:32:45 +0000 and my time is 09:59:55 KST. Does that matter? If so, what else do I do?
3. In Odin, if I put the BL, AP, CP files in and put the HOME_CSC file in the CSC, it won't delete my pictures right?
4. Anything else I should be doing to recover my pictures? i.e. is what I am trying to do going to work?
Thank you so much for any assistance, I appreciate it!

Sounds to me to be exactly as you're guessing. The phone orig was unlocked and XAA. But with the VZW sim it becomes as u have now.
So flash the XAA, it shouldn't change from the pattern it is now. And yes, home CSC avoids deleting apps and data, which is what you want.
Odd though you're needing to do this? Was it due to an update gone wrong? Something you did?
cheers

Thank you for the reply.
It was randomly rebooting daily. Device care said battery issue. Not sure if it was a hardware or software issue. I let it do the latest update that I had been putting off and it bricked. Not sure if it rebooted during the update or it was already in a bad state and the update failed.
Hi im trying to unlock my S23 Ultra I bought from fi.google.com, but don't have the option to unlock.

Nope. you can switch between U and U1 firmware but nothing really changes but if you try to flash other model firmware you either get an error or possibly brick the device. Samsung made sure the north American models wouldn't be able to be unlocked to be able to unlock the bootloader ever.

Does this mean that if I have activated my U1 in North America using a US Sim Card I still can not use a SIM card from another country while traveling? Or does the restriction go away once I activated it?

SIM lock ≠ OEM LOCK
I'm pretty sure you can just swap your SIM if you wanted (as long as your CSC is unlocked carrier like XAA)
