Hi everyone,
I've purchased a Korean Galaxy Note 8 (SM-N950N) and rooted it with TWRP and SuperSu. Now I want to change CSC to Vietnam.
I already download 2 stock firmwares (Korean and Vietnamese).
Can you please guide me for next steps with Odin?
just go grab the S8 CSC changer and use that. All we have to do is add 1 line in one of it's scripts so that it will run on a device with 'greatlte' in the name.

Another user posted in one of the most recent pages exactly what needs to be edited for it to run on a Note 8. Super easy, takes 2 seconds to do, then you just zip it up again and flash/run it in TWRP.

It seems that this CSC Selection file did not work for me even I already updated the script file META-INF/com/google/android/updater-script with this code:
getprop("ro.product.device") == "greatlte" || getprop("ro.build.product") == "greatlte" || getprop("ro.product.name") == "greatlte" ||
When I flashed zip file I got error no digest file found
I have this problem could not find any specific answer so far. I'm from UK with an international Note 8 (N950F) unlocked and want to use it with THREE, especially from the wi-fi calling. So, downloaded THREE firmware and after extraction, I got CSC and HOME_CSC among others. First, through ODIN installed HOME_CSC after reboot could not notice any difference at all, the mobile seems the same so decided to install the CSC which obviously wipe the Note. The same, nothing different on the phone. Lastly, I installed everything (AP, BL, CP, CSC) only that way I got Wi-FI calling but also many apps from THREE ( Deezer, Three, Three likes, Ebay, Amazon Underground, Prime video, Amazon MDIP, Operator Settings) and a horrible start-up boot logo and so on. Despite I got Wi-Fi calling I got more stuff and I am not happy at all. Thinking seriously to go back to the international version I had. Does anyone know why after changing the CSC was not any difference in my Note?
Find attached two pictures, first one shows the wi-fi calling option under Contacts-Settings using THREE firmware, and the other one is from the UK international firmware where wi-fi calling option is not there.
Khoanb1, Kett_Traveler modified the S8 CSC Changer zip to work for the Note 8 but only added the USA CSC to it because that's what he needed. I've since took his zip and added the Canadian Multi-CSC (XAC) for myself and the European Multi-CSC (DBT) for you. The European Multi-CSC (DBT) contains the Vietnam CSC (XXV). Download the zip from MEGA here and install it with TWRP. When it asks you which CSC to install, choose DBT, then choose XXV in the next screen to select your Vietnam CSC. Make sure to select XXV and not keep it at the default of DBT at the 2nd menu.
I've successfully used this zip to change my CSC to the Canadian one. Note that after the CSC change, your phone will factory reset itself and wipe all your data (if I remember correctly). So make sure to backup externally first if needed. After a restart, your phone will boot up with the proper boot animation for your CSC and you'll have all your carrier-specific features. For me, changing my CSC allowed me to connect to LTE networks which was not possible before (I was limited to 4G speeds instead). Also, the Korean apps that came with the phone are preloaded onto our system partition, so you have to delete them from /system/apps or through Titanium Backup. You can also freeze them if you prefer.
Note: I haven't tested the install with the XXV CSC so test it and tell me if it works.

Hi peacey8,
Thank you very much for your effort and your thorough guidance. Your zipped file worked very well for my device and now I could have XXV CSC code in my Galaxy Note 8.
I can see some big changes:
1. boot logo is the same with Note 8 devices distributed in Vietnam
2. some apps were installed by default like these devices
3. Samsung Pay can recognise Vietnamese network providers (but I could not still use it because my device was rooted). If you have any idea about it, please let me know.
Great! I'm glad it worked. Unfortunately, Samsung Pay will not work because Knox was tripped. Android Pay still works though if you use Magisk root with Magisk Hide.
Right now there is no solution to Samsung Pay with root. In the future there could be some solution. I'm sure some creative person will come up with something eventually.

Hi peacey8,
Thank you for your explaination. I have another question:
What will happen if I flash all tar files in the Vietnamese stock firmware to my Korean Note 8?
Will I get the CSC code like devices distributed in Vietnam? And will Odin allow me to do this?

Honestly I'm not sure if it's impossible. I'll let someone more knowledgeable than me answer that question. However the Korean Note 8 and the Vietnamese Note 8 are both running on the Exynos SoC, so it might be possible to switch firmwares with a lot of hard work and many problems. For one, the devices have different storage capacities and so will have different PIT files (the file that determines which tar image file goes where and how big it should be). Another issue is the bootloader (the most basic, low-level software of the phone that talks to the hardware to start your phone up) is different for the Korean and European models, so you can't flash the Vietnamese BL file on the Korean model. It would brick the phone if you did.
So in short, no you can't flash a different firmware. But, why do you need to? What's wrong with the current solution of switching CSCs that you just did? Is there still a feature you are missing?

i've used a similar file for the S8+ and my phone rebooted with a new CSC and the message "Android is updgrading"... but it did not wipe my phone.

It's only a question because I'm so confused if I can totally convert my Korean device to Vietnamese one.
You are right, so dangerous to replace bootloader even I already created backup for all partitions.

Hi Khoanb1,
Luckily i found your thread up here, i'm a clueless Vietnamese when it come to rooting phone and other related things. I also bought an KR Galaxy Note 8 lately and have been wondered since then. Is there any other feature that missing on an KR note 8 to a distributed VN note 8?
Would you be so kind to instruct me install them just like you did? im a total noob here.
If you dont mind i can ask for your social media account so we can discuss further.

Hi lluvias91,
I already sent you a private message including my fb account, let's start our converstion about this topic
do you know guys if a packed Note 8 Eng Boot for Exynos variant (SM-N950F) is available ?
tengo el inconveniente con el n950F Exynos sin interruptor de desbloqueo OEM Ayuda
I have the N950F Exynos phone and want to flash the US Mobile CSC to get Wi-Fi calling. I don't have root and am in jail with the no oem unlock issue. I was wondering if I could just flash the CSC from the complete N950U firmware using ODIN. Or can you not mix the F firmware files with the U versions?
I saw the zip file to do the same but it requires root and TWRP to flash.
Not sure I like this phone being locked down. Very frustrating not being able to just root and install a working ROM without having to wait 7 days!
Thanks
In download mode. My carrier id is blank. How do i add the id back?
Hi guys
I buy mine in Morocco N950F Dual Sim (Exact version : SM-N950FZDDMWD).
My phone are not rooted and i dont want to do it for the moment. dont want to increment the knox
I need the french CSC. If i downlaod a french stock firmware N950F and install it with Odin.
It will work without loosing my garante and continue to use samsung Pay ?
Sorry for my bad english
thanks in advance

*EDIT 2018 January so you don't need to read 7 billion pages of this thread*
It took 3 months but I finally figured out how to get T-Mobile Wifi Calling to work properly on the N950N's firmware.
Please see this thread for the patch updates: [MOD] Exynos T-Mobile CSC Wifi Calling, VoLTE etc for N950N / N950F
Trying to get wifi calling working with my SM-N950N (South Korean model from SK Telecom) to work on T-Mobile here, and as I understand it we need the proper CSC flashed.
Now, I probably am just overlooking something (hopefully) but can't seem to get this phone to take. I downloaded both firmwares from Sammobile (paid for a month premium membership),
pulled the cache.img.ext4 file out of the TMB CSC tar.md5,
pulled the PIT file out of the Korean CSC .tar.md5,
in the PIT changed the file name from cache.img (original) to match the TMB file name cache.img.ext4 and adjusted the partition size and block value for the CSC partition,
adjusted the block values for the 4 partitions listed after it to account for the double sized new one
built a new .tar.md5 with the modified Korean CSC PIT file, the TMB cache.img.ext4 file, and the omr.img file that was in the original Korean CSC .tar.md5
I tried this with and without Re-partition checked, tried adding the remaining files into each field (BL, AP, etc) along with it, and tried an old 1.87 version of Odin (mainly trying to use 3.12.7 from Sammobile).
No matter what I try Odin errors immediately saying that repartitioning failed.
Any suggestions as to how I can get this to flash?
following, Also have the South Korea version and i want to Change Csc and debrand it
been poking around with a few things at work today, was able to get some settings changed by granting an app secure write permissions over ADB but I am even more convinced that the CSC needs to be flashed somehow. I got into some currently-hidden menus with settings for IMS, VoLTE, and WiFi calling but some of them crash if you try to enable it, others are disabled, and others pretend to be doing something before reverting back to 'off'.
I'll look into this more tomorrow and ask on Sammobile to broaden the knowledge pool.

On the SM-N950N you can only flash -N- firmware!
Don't mess around with other FW's!

I know from experience and XDA that this is false. I'm not sure if you're aware of what we do here on XDA but flashing different and custom firmware is the name of the game.
If you're afraid of that, best stick to your OEM updates and keep misinformed comments to yourself.
Can anyone who knows about this stuff think of what step i may be missing here? I don't understand why it won't repartition in Odin, but as far as I can tell this should be working since i adjusted the sizes in the PIT file to match the larger CSC partition.

Well sir, you are replying to my thread with false information. I am working to flash a USA T-Mobile CSC to my Korean model phone. It can be done, and I am asking for people who know more about this than I currently do for suggestions.
You obviously don't know at least more than me, since you felt it prudent ti post your false claim that only firmware created by Samsung for a specific model can be flashed to that model. I respect your right do do whatever you want with your phone, but your words are not true and you're not helping anyone by posting them in my thread here.
I never said I cared about KNOX (which I don't, I have a phone sold in a country on the other side of Earth, and I am on XDA which generally means I prefer modifying my devices).
Thank you and good day, but please don't post false information. People can flash whatever they want to their phones, regardless of what you or Samsung might wish.
Don't try to be smart...!

Are you sure about that?
I'll tell my boss at Samsung NL...! :silly:
Oooo who's right? Look forward to seeing the outcome of this...
It might have something to do with different processor. The US CSC is for snapdragon and the SK CSC for the Exynos. Just a thought.

Yeah, I had suspected that but on the S8 forums someone specifically said that CSC were universal and that you can switch between them on Snapdragon and Exynos models.
In any case, I did finally get it to work via flash able zip but also learned that the CSC on these latest flagship models is just a folder /system/csc/ that you can overwrite the entire contents of with a file manager once you have root.
After that and a reboot, phone info apps now show the correct available CSCs but still show SKC as the loaded one so I'm close but 1 step away. The IMS settings app has all the T-mobile data now, but I still can't confirm VoLTE or wifi calling and that settings app shows no IMS profiles registered still.
Getting close, I just wish one of these smart developers would give me a hand so I knew more what I was doing :good:
per this thread: https://forum.xda-developers.com/showpost.php?p=71192951&postcount=5226
I fixed the folder and file permissions, as well as replaced the OMC folder contents to match a T-Mobile phone as well.
That REALLY made it angry. upon reboot I couldn't get any cell service and it said there was no SIM card installed, on top of other Korean provider apps now appearing (instead of just the SK Telecom apps that were initially visible).
So I'm guessing that these phones go by the OMC rather than CSC but since replacing that made it not work at all I'm a little unsure of how to proceed.
I copied the stock OMC files back over, fixing permissions per that thread, rebooted and now I'm back to where I was before replacing the OMC folder contents. Phone works fine, i get fast LTE but still no wifi calling or VoLTE that I can tell, and the IMS is not registering (which is probably the cause of both).
After reading this thread about the S8's: https://forum.xda-developers.com/galaxy-s8+/help/adding-att-volte-wifi-calling-t3599439/page5
I copied the Tmobile OMC files over again, fixed permissions, and edited /efs/imie/mps_code.dat, and changed it to TMB and rebooted. Got the Tmobile boot screen instead of SK Telecom (along with annoying T-jingle sound), but phone app FQs indefinitely, no network service, and I can't view mobile networks. Trying to view more connection settings closes the settings app.
however, Phone Info app now shows Original CSC: TMB, Firmware CSC: XAA, Active CSC: TMB but Product Code, Available CSC Codes, and Mobile Operator are now blank.
Getting really close here, but it seems like there are probably some other files that need to be copied over, and I am not sure what they are. Thinking perhaps stuff to do with the T-Mobile variant's apps/settings apps.
Thoughts?
Good news - almost everything is working thanks to the good folks in the S8 forums per this CSC changer zip: https://forum.xda-developers.com/ga...lashable-csc-selection-v1-1-0-t3636739/page31
On a hunch I tried to just run it and see what happened. After repackaging his zip after replacing the XAA and TMB omc folders within it from those from an SM-N950U T-Mobile ROM, I used my modified version to update to TMB and this time no crashing on bootup, LTE still working, Wifi still working, and as far as I can tell VoLTE is working because it didn't drop me from LTE to 3g when making a voice call, though I do not see a VoLTE icon or any VoLTE menu options still.
Not sure if working: Wifi Calling, as I don't see an icon or menu options either, but running the Tmobile WFC settings app with a shortcut app showed that it was enabled but the toggle is greyed out, but I made a call with mobile data supposedly turned off and WiFi on and it said it was an HD Voice call in the dialer. Oh and the dialer claims to be new and for video calling, but I don't know anyone on Tmobile with video calling to test that out.
If I can confirm that WiFi calling is somehow working then this solves all the problems for us importing Exynos models.
Hey can you share your script? Mine is having issue making calls on t mobile.
Would be appreciated.

yeah I am trying to find a way to upload it, even after deleting a bunch of the S8 stuff from it, it's still 361mb. I'll see if I can delete out anything else.
*edit*
Does this Mega link work? https://mega.nz/#!43wERRoQ!0d2AbZzuNtkIJE9k96mq-VAGXc-F_SOa3fX7xQjQQJ0
also - I only put the Note 8 XAA and TMB omc folders in there, so if you pick any other CSC options instead of those I don't think it will even run.

Glad it worked for you. I would love to help the creator of that utility properly add support for our devices so that we have all the menu options, icons, etc.
well I read over that thread again and it said to get Wifi Calling working on Tmobile to first flash the ZTO CSC first, reboot and let the phone finish booting, then go back to TWRP and flash the Tmobile CSC and you should be able to enable wifi calling with a shorcuts app to launch a Wifi Calling Activity action but I still don't think it's working. Also I am looking at the ZTO CSC stuff and not seeing why adding it first would make any difference.
I followed a guide by XDA User applepay from this link, but just wanted to try and simplify it because i found it pretty complicated to understand at first.
It would be worth reading that thread before this even if it doesn't make sense. Please also read this complete thread before you attempt it.
I have only followed the guide so i can't answer any questions to help. I am not responsible for any problems you run into. This is just a guide of what I did to get mine to work.
I was successful using my SM-N960F going from CSC XME to TEL.
I cannot confirm that this method will work on other models, but i don't see why not considering the guide was originally for a S9.
Make sure you select your exact model when downloading files and flashing files. Using other model firmware may brick your phone.
Backup your files! I used Smart Switch on windows. This method will wipe your phone in the process.
Use the original usb cable you got in the box and install the Samsung USB drivers if you haven't already.
I have confirmed on my device that OTA updates work fine after this procedure.
Please comment if you think there is a better way or there is an error in this guide.
Download your combination file from here
Download your new CSC firmware from here
Download Samsung Odin 3.13.1 from here
Download RealTerm from here

5. Enter "AT+PRECONFG=1,0" and click Send ASCII.
You will get this response.
AT+PRECONFIG=1,0+PRECONFG:1,???
OK
-??? is your changed, current CSC.-
6. CSC change is now complete. You can now close RealTerm.
7. Open Odin again.
Turn your phone off and then put it into download mode again by holding the volume down and Bixby buttons, then plugging the usb cable in.
Fill each field (BL, AP, CP and CSC) with their respective files from the firmware which has the new CSC.
Use the CSC file in the CSC field, not HOME_CSC.
Click start. This will now wipe your phone completely.
8. Your phone should boot into android and everything should be complete!
Enjoy using VoLTE, VoWiFi and RCS!
Many thanks! Will give it a go.

Hmm, will this allow my unrooted n960f/ds to flash the TMB CSC and work? Or does this just let you change to another CSC within the multi CSC?

Odin still won't let you flash firmware files from an other phone model. which is a good thing since csc.md5 contains a pit file that is very much phone model specific....you dont want that. home_csc.md5 dosent but regardless Odin should still throw an error. I wouldint be game to test with the prince Comey edition of Odin that allows you to do this forcefully apply wrong model firmware file. might work... or not
how about future OTAs after ? if I flashed TMO csc will I get all TMO OTAs in future ?
@laneyyy i need to select combinations file Odion in AP right ? I guess I have to downgrade my firmware first Odin don't let me flash I have the last one firmware

My phone was up to date before I used the latest combination file for my model on that site. I didn't get any errors about downgrading.
As far as OTAs, I'm not sure yet, but worst case is you just need to flash new firmwares by Odin. I think it's definitely worth the trade off to get volte, vowifi and RCS if that's the case

someone please confirm that N9600 chinese snapdragon variant can have working Volte after changing CSC to any US version.
Why the Heck Samsung put region lock! if they do same thing on S10 then I must say goodbye to Samsung for ever!!
we cant even buy a mobile in a foreign country! ?

I can confirm it worked to replace the hedious Hong Kong CSC with a Costa Rica CSC, but just as others, I would like to see if I can use a firmware from US, meaning using a SM-N960U variant on a SM-N9600. Can someone please confirm?

+1 using cho firmware
guys just use samfirm tool 0.3.6 on your PC to check for the update. no need to ask or post if its out or not:
enter as device model:
SM-960N
And Region: dosent really matter but u can choose the carrier that the device is from:
LUC
KOO input this one if unsure
SKC
KTC
or choose the one with the latest fimrware/date code
(but rightnow only May is available)
check regularly as the app seems to connect to samsung servers so it will be the first place for the firmware to pop up.( and download speeds are fast. way faster than sammobile free or other crapy sites.)
https://forum.xda-developers.com/ga...g-firmware-t2988647/post57842725#post57842725
to dl the tool on the post link above , skip the part where it says depreciated and dl it from attached OP post. read up though on the windows ( MS redist) dependencies to run it.
downloaded firmware is flashable once extracted using odin 3.13.3 from here:
https://dl2018.sammobile.com/Odin3-v3.13.3.zip
this required to see phone com port with odin
samsung usb drivers:
https://drivers.softpedia.com/get/M...ver-for-Mobile-Phones-1-5-65-0.shtml#download
put phone into download mode:
(make sure your device is off before doing anything.) hold the following button combo: VOLUME DOWN + BIXBY and plug usb cable from PC to phone then release button when you see DL mode and press vol up to accept to enter it.
in odin:
to not reset/wipe data fill in all slots with unziped md5's from file downloaded with samfirm: BL, AP, CP AND CSC (use ONLY these 4 corresponding files*)
(* For csc: home_csc.md5 is to not loose data and regular *csc.md5 will wipe clean.) (userdat.md5 is korean bloat, skip it not needed if you are not on korean sim carrier)
if you are on a custom rom(rooted device) and just want to update bootlaoder and modem to latest, then flash only ;
BL.md5 and CP.md5 in the according slots.
flashing official firmware and components like this dosent trip knox or voids warranty so its all safe.
edited for links to the tools needed and some clarifications.

with root its easy. but without i dont know.
try to install the KOO firmware. i believe it is the "unbranded" firmware for korean n960n devices.
be careful of personal data if you try. using the method described above to flash with odin.( the part when using csc.md5 file because i might wipe data from phone. but it might also remove bootlogo and more bloatware apps from korea)

I tried flash trwp crownite and failed at flashing via odin, i think is not working for now (pie)
This is my buildnumber N960NKSU2CSE3 this for baseband N960NKOU2CSD2 if i download KOO firmware
which one should I choose? Buildnumber or base band?
Btw i got firmware KOO but unziped file i get 6 fil, AP, BL, CP, CSC, HOME CSC, and USER Data how i must input User Data File to?
I'm in Korea too, using an unbranded KOO N960N (exynos). It seems like the update is unavailable in this region. I left a question on the Samsung Members forum, and it seems like they're saying the night sight camera mode had some pretty large bugs, so they have to fix that. Also, the night sight camera update was just released for the S9 series, so hopefully it shouldn't be long before we can get it for the Note 9.
[edit]
Also, checking the latest firmware for N960N in SAMFIRM results in the same firmware, an outdated May 2019 version withOUT night sight camera. Looks like we will have to await the official release ...
This sucks because my Mate 20 Pro takes absolutely stunning pics at night.

moreover you might need to install samsung android drivers. you can search for them on xda or you can install samsung smart switch. it has the drivers built in. the software is useless it is only being installed for the driver package.

u have to flash a minimum of BL AP CP CSC
there will always be some carrier bloat leftover. the only way is to root and install a custom rom to get rid of everything.
For those who don't know, F916U is the model number of all of the US carrier versions of the Galaxy Z Fold2 5G. The F916U1 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. 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.
These files that I'm posting are used for converting from one carrier's U firmware to AT&T's, or from U1 firmware back to U firmware with AT&T features and bloat. These are much tougher to find than other carriers' files due to AT&T's policy against public hosting of their firmware files - they can't be obtained from SamFirm or Frija or SamMobile. But I pay for a subscription to a site that gets AT&T files, and also sometimes gets other carriers' firmware files before they hit SamFirm/Frija, so that's where my files come from.
So I'll be uploading at least one USERDATA for each bootloader version, and I'll do the full firmware (for at least one build per bootloader level) if AT&T was the only carrier to get that specific build.
Since firmware is universal on U models, for a full flash you can use the other 4 Odin files (BL, AP, CP, CSC) from any other firmware of the same build - and you can almost always obtain what you need via SamFirm/Frija or AFH or SamMobile (if you have a premium subscription). You can probably even mix and match builds (as long as the Android version is the same), if you can't find files for the exact same build. You can't mix and match bootloaders though, so the other 4 files have to at least be from the same bootloader level.
Happy flashing!

NOTES:
- Please don't quote the OP when replying, kthx
- I compress extra small for space and bandwidth savings. The default Windows extractor can't handle it, so you'll need a 3rd party tool like 7zip, WinRAR, etc
- I won't be providing detailed instructions on how to flash files in Odin. If you're not aware of how to do that, there are countless "beginner's guide to Odin flashing"-type threads here on XDA already
- My naming method for AFH 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.
- the correct procedure for switching from one carrier's firmware to another is:
1. Flash full U1 firmware package including non HOME CSC
2. Upon boot, insert a SIM of the carrier whose firmware you want
3. Watch for the popup that says "reboot to apply new carrier settings" etc, and do it
4. After that restart completes, reboot back to Download mode and flash the full U firmware package, with the USERDATA file of the carrier whose firmware you want
- USERDATAs for any other CSCs/regions can be gotten from SamFirm or Frija - for the latest version. If you need an old USERDATA for a CSC/region that's not commonly found, let me know and I can probably get it
- For identifying USERDATAS, and to know what region/CSC to use in SamFirm/Frija:
AIO = Cricket (not available via SamFirm/Frija)
ATT = AT&T (not available via SamFirm/Frija)
BST = Boost Mobile
CCT = Xfinity Mobile (Comcast)
CHA = Spectrum Mobile (Charter)
SPR = Sprint
TMB = T-Mobile
TMK = Metro PCS
USC = US Cellular
VZW = Verizon (available via SamFirm/Frija, but Manual Entry is required - Auto will not work)
XAA = U1 firmware
FYI, this file will appear corrupted if you try to use the built in Windows zip extraction. I was only able to extract it with 7-zip.

After following all instructions to the letter in both this thread's OP and this one: https://forum.xda-developers.com/sa...axy-z-fold-2-odin-launch-firmware-sm-t4161413
Upon first boot I inserted the SIM and DIDN'T GET THE POP-UP described above.
I got a fresh phone with Spanish as the default language, (easily changed it to US English) and THERE'S NO AT&T ANYTHING ON IT!
No WiFi calling, No Visual Voicemail.
BTW, I did it ALL TWICE, just in case I missed something.

Spanish doesn't come as the default language on ANY U or U1 firmware. I have no idea what firmware you flashed, but you need to go talk to whoever posted it about the janky firmware that they're putting on XDA

Actually, I had the same problem with this firmware. As the poster says, it booted to Spanish (which I was able to set back to English), and without any hint of it being an ATT phone (no logo, no carrier features). I spent an evening working on it, and finally just got frustrated and sent the phone back for a refund. I'm a reasonably educated user, and was successful doing the same thing to a Note 20 Ultra, but was unable to get it to work with the Fold.
I'd really like to see it working though. If I could get it to work, I'd go back to the phone.

Juggamonkey posted in the other thread with the f916 firmwares, that they flashed the u1 firmware to their AT&T f916 and it resulted with PCT/PCT/ATT which is likely Puerto Rico region. My guess it would default to Spanish. I personally haven't had the need to use your file at this time. Also I have never had any issues with your prior files. Thank you posting the USERDATA!

Hmmm interesting. PCT is a Puerto Rico CSC/Region for Samsung, yes. But I've never seen it on any American models before. Puerto Rican carriers have always sold models from the Central/South American region, with model numbers ending in something other than U. But I suppose they may have changed things up this time

Any update on this? I have S21 Ultra with TPA and I want to change the CSC to BTU. I am in Canada and I hope this will help with faster updates. Also I am having problems with slow 4G uploads, and faster updates might be the solution.

If your device is SD then you won't be able to get BTU.
If it is exynos then you can flash the BTU firmware.
Your 4g speeds may be slow if you do not have the correct csc files for your provider. Eg: having BTU for Rogers may not get your the speeds you are looking for.

i dont have volte in my country , no 5g in my country , no google pay in my country , no samsung pay in my country , no PayPal in my country , no paid app or watchface appears in galaxy store in my country , bad bad bad .
I used the link in this tread and I selected BTU, but I did not pay attention that it was mentioned that is Single. Now I have BTU, but I have some problems receiving SMS and I cannot go back to TPA. When I try *#272* IMEI# it does not do anything. Any idea what I have to do to go back to Dual SIM?

I have Exynos device. If I do Canadian CSC on Exynos S21 Ultra, will I have better 4G in Canada?

You will not be able flash Canadian CSC on an exynos device.
First you have to root the device and Either you or some else will have to edit the canadian csc file to make it compatible wtih exynos.
Some one has done for me in the past with note 8 but that dev is no longer in XDA.
The other option is to root and then copy the required csc files.
With this there is a high chance that the imeir related files can get corrupted.

You can flash any other file with multicsc.
There is no reason for you not recieve sms with BTU csc. However, if it does happen fhe csc firmware that is the original one. i.e look at the third tri letter in the csc info.(this third letter never changes , more like hard coded)
I do get SMSs but, I was not able to get one from my bank. The 3rd 3 letters are still TPA. I do not know if it is normal, but the dual sim menu has much fewer options. I can choose from what sim to call only after I dial at least one digit. And When I try to activate Dual sim always on, the toggle still stays off.
For the Canadian CSC, I suspected that it will be impossible to flash. I used to be on TPA and now I am on BTU, I had problems slow upload speed on 4G. Now is a bit better, but the download is staying around 50-75. before I had 160-300 Mbps.
Where I can get Multicsc and do I have to root the phone?
Thank you.

Rooting won't help you much with signal or speed of data, unless you have to flash some modified csc files.
Your problem could also be the absence of the required bands,whuch may be lacking in exynos.
I have a SD version ( decided to go wtih non root this time as most of the things that need root can be done with adb anyways. Also there is root for SD too these days) so cannot help you much.

I am missing only one band, and this is not a problem. B29 in LTE. Al the rest are there. My question was more like is it normally to loose t some fucntciuts of Dual sim manager and and is there an easy way to change back and forth CSC without rooting. I do not want to root. Thank. you

Chainging csc is easy by flashing the CSC file. Rooting won't affect it. Rooting has its downsides.
Your loss of dual sim fn could be related to csc but BTU should support full dual sim fn.
