Country/Region, csc code change. - Samsung Galaxy S21 Guides, News

I'm new to this so please bear with me.
Found this helpful and working, https://www.droidviews.com/how-to-change-csc-in-samsung-galaxy-phones/
It's free and only requires patience and time.
So here it goes:
1. Unlock your bootloader (easy for Exynos, just go to developer mode and enable OEM unlocking followed by download mode and long press of volume plus + button)
2. Flash twrp using odin. Follow this guide here. Works perfectly https://forum.xda-developers.com/t/recovery-unofficial-twrp-for-galaxy-s21-exynos.4241869/
3. Flash the latest magisk.zip using twrp. https://magiskapp.com/zip/ (the phone will take a little longer to boot Be patient! Open the magisk app once booted. You'll be greeted with a popup just click on install and reboot then you'll have properly working magisk with su rights.)
4. Install any root explorer and set permissions from R/O to R/W. And then head to this path "/efi/imei/" and edit the file *mps_code.dat* . (Replace it with the country code that you want. In my case "INU") once done save the file. Here it's done if you're okay with having just one sim for your specified csc.
5. If you want both the sims to have the same csc code then head to "/system/csc/" folder and replace the csc in the file named as *sales_code.dat* once done save the file and reboot the phone.
6. you should now have your specified csc in settings/about/software information.
7. Now you can go ahead and flash your phone with a new firmware using odin. Do not try to reset or relock the bootloader without flashing. It will not work. Software mismatch errors will show.
8. Once done with flashing your phone will boot normally and you can set it up and start using . For my case samsung pay and call recording wasn't working. As the phone was purchased in UAE.
Here are some screenshots .

Is this workig with androud 12? Can someone confirm please.

sorry for the noob question, its my first Samsung, whatis the meaning of changing csc codes?

Looking for some similar info.
I have an S21 5g, singapore rom. I wanted to unlock all the LTE bands, or find a CSC that matches my countries bands, as the there is no Canadian CSC for the exynos variant that I can find.
Anyone know how if there is a CSC code, or rom version for exynos that unlocks all the bands? or lets me select the ones I want?

[Q] To unlock Note it needs to be rooted?

Hi, guys!
Yeeey, I've got myself a white Samsung Galaxy Note. Lovely little thing. BUT, I am on Giffgaff (was/will have been), and the Note is locked to Vodafone. I am in the UK and it is for Vodafone UK. I checked and it won't accept any other card (T-Mobile, nor Giffgaff).. It is 2.3.6 Gingerbread.
Sooooo... I searched this forum and yes there a few threads that give solutions, but some of them aren't quite clear on whether certain method applies to this, other, or all countries...
My first question, before I as noob that I am attempt to unlock my Note, is "does the Note need to be rooted in order to unlock it using that one app that unlocks the Note?
And what is the simplest UK version?
Do I need to have a Vodafone sim too, before I can unlock the Note?
For some reason can't connect to my wifi (password in and all, but when it connects, then saving, then disabled), so how can i download the specific app on my laptop and then install it on the Note?
Thanks folks!
to release the notes no brand, you have to download a firmware stocks here http://www.sammobile.com/firmware/ ... Install Kies on your computer, connect your phone and make sure that all the drivers installed correctly.
Extract tar file from the ROM(remember to extract it till tar, dont go deep). Put the phone into download mode (vol. down+home+power buttons), Start odin, then only connect the phone via USB. Choose continue on the phone, Now ID:COM box shud turn yellow
Make sure that only two boxes are checked in odin - Auto Reboot and F.Reset Time.- If your downloaded ROM contains single file Choose PDA button in Odin and select tar file you extracted before. Download odin here : http://forum.xda-developers.com/attachment.php?attachmentid=771703&d=1320429195 ... - If your downloaded file contains multifiles Choose CODE in PDA, MODEM in PHONE, Multi CSC in CSC ... Choose START button.
The phone will reboot after the flash. Done. no matter you have permission of root
So, I have to root, no matter what? I was thinking there was a way of doing it (only the UNLOCKING part!) somehow less invasively...
Will this method you described, leave me with the Note as it is in terms of Gingerbread, apps installed, etc., minus of being unlocked and rooted?
If I'm gonna step into the territory of rooting my Note, why would I not go straight for the Rocket 4.1 Rom , or KingDroid whatever latest version for Note?
On these forums and da internet they seem to get most positive attention and reactions, no?
I'm in no rush (not a mater of hours, but I'd like to do it till Sunday evening), so I am willing to follow longer, safer way of doing stuff...
Anybody from the UK to voice their opinion?
Thanks...
Please install cooked rom if you want (es.cyanogen). with root permissions and recovery then follow this guide carefully : http://forum.xda-developers.com/showthread.php?t=1424997 ..

CSC Change

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

How to get SM-N920I to detect VoLTE in india without root

Hi fellow XDA members,
I own a Galaxy Note 5 (SM-N920I) which was bought in Singapore under operator Starhub (STH). I happen to use this phone in India and I later realized the phone supports VoLTE but the firmware didn't so I stuck with using the Jio4GVoice app for a long time now and I'm done with it due to lot of bugs and call drops.
I looked online for solutions and found many that involved root or custom recovery to flash the so-called VoLTE fix. I have read articles that said the Indian firmware supports VoLTE so I So, I tried the following:
Download the Indian firmware and flashed via odin. But it fails with error specified file not found. Did a research and i unchecked the Re-partition and again tried and it fails at flashing system . So I re-flashed the STH firmware to get the phone boot up. I learnt that CSC is responsible for getting the region specific network to work.
Extract CSC from Indian firmware and simply flash it on odin. But, as articles say that I'll have 4 files for each boxes to place in odin I only had one tar (<firmware_HOME_tar.md5). Then I read, extracting the modem.bin file and ziping that to a tar file and flash it via odin will help. I tried that but no luck (should I factory reset it?).
Both the firmwares have a single file and articles say that there will be CSC_<firmware>.tar and CSC_HOME_<firmware>.tar.
I don't know where I'm getting wrong. Is this even possible or i'm simply wasting my time? I use samsung pay and S health extensively so I don't wanna trip knox.
Update:
I read that cache.img is CSC from here. So extracted the cache from Indian firmware and flashed that to my phone that has STH firmware. I used the Phone info app and found baseband has been changed and available CSC shows INS but active CSC is STH. Now I guess i just need to activate that CSC. I tried the steps mentioned here but it doesn't work.

here is another method you can try. but this only works if your phone supports it.
For firmware that uses a multi-csc code, you need to select a sales code before attempting to connect to a cellular network. This is especially true for 3G and 4G connections.
There are two ways to select a sales code:
1. Enter *#06# in the phone dialer to obtain the IMEI number for the device. You can then enter *#272*Device IMEI# to select a sales code. If your Samsung device does not return a menu, the product code is not a multi-csc code.
OR
2. Install an CSC changer app, such as the "Phone INFO" app. CSC changer apps do require root access, and they do not work on all phones and all versions of Android.
Hit thanks if it helps !
P.S. IT ONLY WORKS ON STOCK ROM ...! so you need to be on Stock Rom.

Thanks for your help. I tried solution 1 and it Worked
However, before trying out your solution, my device was in this state:
1. Flashed Singapore ROM
2. Extracted every file from Indian rom and repacked the tar except the system.img (as this was failing to flash in odin)
3. After booting I got a notification from SupportAgent telling me that unauthorized changes have been made, tap here to reboot to undo those changes
4. I then read your solution and updated the CSC to INS from STH. And device got factory reset and for the first time I saw VoLTE logo on my phone :victory:
5. I finished the setup and still getting the same error in notification from SupportAgent. So I tapped on it, and device rebooted to a new blue screen with sim card logo on it and then boot up to system.
6. Now, in the quick settings, VoLTE toggle is gone and I got WiFi Calling toggle instead. However I still have the VoLTE icon on the status bar.
7. So later that day, I redo all the steps.
- Flashed Singapore firmware (This time, the CSC Country was Singapore and the active CSC was XTH instead of STH. There was VoLTE toggle)
- Flashed Cache from Indian Firmware (CSC Country changed to India the active CSC was INS automatically. Now got WiFi Calling toggle)
8. I noticed other changes in the software:
- The gallery App doesn't show Grid view so I'm stuck with List view
- The Samsung Pay says, its not supported for this device
What do you think about this?

are you still able to use voLTE ?? after these steps.
about Support agent. Ignore it if you can. or skip it. you do not need this as there aren't any official updates after this. (this is only because now system knows that you have modified it, and it will not receive any update. if you can the disable the Support agent app via settings or if possible via root.)
samsung pay will Not work. as knox should have been tripped to 0x1, so Samsung pay like apps will NEVER work after knox trip.

[U/U1][02/2021][FUA1]Note 9 Official Firmware and Guide to Convert to USA Unlocked

[Updated][ETH1]
If you only want the firmware and know what you're doing, then links will be at bottom.
If possible, Use the original charging cable that came with your phone, as sometimes there can be errors if you use an aftermarket cable.
If you don't know how to flash or convert from U to U1, read on.
As a precaution, I recommend removing your SIM card and SD card before flashing!
THIS WILL RESET YOUR PHONE!
Firstly, Download the modified Odin below as well as the firmware.
Step 1. Ensure that you have the Samsung drivers for mobile devices installed (which will also be linked below.)
Step 2.Extract the Firmware Zip that you downloaded, Open the modified Odin and click on the BL box, Then select the corresponding BL file.
Click the AP box and select the AP file, Do the same with the CP and CSC files by putting the matching file name into the corresponding boxes.
Step 3.Ensure USB Debugging is enabled and then shut down the phone. Then hold (In this order) Volume Down, Bixby, and Power button until you get to the Download mode warning screen.
Press the Volume Up button.
Step 4. Plug in the phone, and check Odin to ensure you see a blue box that says COM (also has a number at the end)
Step 5.Press Start in Odin and wait till you see pass, if it says PASS, The flash was successful and within about 10 minutes your phone will boot into the welcome screen.
If you are converting from the U firmware to the U1 firmware then you will have no carrier bloatware should have better performance and possibly better battery life as well.

Flas info
Firstly I was on "U1..ARL1" then passed to "U CSAA" ( different than U1) and now I'm running latest N960USQS1CSD1 but my phone is bit laggy and still got the lags/stutters from lock screen when I slide quick menu and animations....Now I want to try itself U1 firmware and I hope all laggy and stutter will gone!
Do I need to roll back to ARL1 then flash CSD1 or I can do that directly?
Thanks
Thanks it worked for me
Flashed without problem but still got the lag when change the wallpaper :crying: If its infinity wallpaper there is no lag, but if I change the laggs/stutter starts.....What I supposed to do? Anyone? Also there is a lag on animations....
I flashed too many times and different firmwares and no luck...

in step 2 you say "Open the modified Odin and click on the BL box, Then select the corresponding BL file.
Click the AP box and select the AP file, Do the same with the CP and CSC files by putting the matching file name into the corresponding boxes."
Yet you only provided the ROM file. Where does the ROM file go and are there other files to flash that go in the CSC, CP BL and AP boxes?

Did you extract the zip? All of the files should be inside the zip.
I'll redownload them to check and make sure.
jd14771 said:
i have not finished downloading the rom file, i did not know the files were zipped inside, i think it would help if you mentioned this as i was ust going to flash the file whole as i downloaded it.
they are most likley there, i did not know to unzip the archive. So this will work on a locked us variant?

Yes it will work on any USA Note 9.
Thank you for bringing that to attention, I will update the thread, I apologize for the confusion.
I'm glad everything worked out okay! I'm at work right now so i apologize for the delayed replies.
Do you have lags/stutters on this firmware? (Especially on lock screen with none infinity wallpaper
when swiping down quick panel?)
Thanks converted AT&T to unlocked and everything is perfect
Will flashing u1 remove a carrier sim lock?

Call recording is only available on certain international firmware. It's a CSC feature that isn't available on the U.S. firmware. If you have root you can add the call recording feature to your CSC and that will be the only way to get call recording unless you find the specific international firmware that has it enabled but that firmware may not be best suited for your carrier/region. Also, enabling call recording will replace the call waiting & "add call" button which will make 3-way calls and ability to answer call waiting a problem. For this reason I always chose to not enable call recording. However, with root you can change csc anytime you need call recording and revert when you no longer need it. If I remember correctly, you also have to do a factory reset when adding the call recording in CSC because the csc/settings database is created on first boot only and adding this line in CSC after the phone has already booted and created it's CSC database will not enable call recording. It must be done on a fresh boot after a wipe/restore. I wanted to give you a heads up based on my experience so you know what to expect. Root is going to be mandatory unless you find the international firmware (rare) that has call recording enabled from Samsung.
Hi,
Here is my note 9 info (8.1.) from AT&T carrier, but I am not living in US.
- Model: SM-N960U
- Firmware: PDA version: N960USQU1ARH2 / CSC version: N960UOYN1ARH2
- Actice CSC code: XAA
- Service Provider:
SAOMC_SM-N960U_OYN_XAA_OO_0007
XAA/XAA/ATT
So can I use the firmware N960U1UES1CSD1 which is uploaded in this thread to flash my phone into 960U1 ?
Or should I use the firmware N960U1UES1CSD1 which is specified for XAA ?

As far as i know u can flash any firmware related to N960U, N960U1 and even N960W.
for specific carriers after flash u will have their bloatwares .
Will a N960U converted this way take OTA updates in the same way that a phone that started out as a N960U1 would?
Is there a way I can make this work on a Linux based OS?

Is this XAA region??

How To Guide [GUIDE] How To Flash Official Samsung Unlocked BloatFree Firmware

Did you just get your shiny new S21 Ultra? And the first thing you noticed is tons of preloaded carrier apps that can't be deleted? This is how to fix that.
Convert your phone into the one that would come from Samsung directly with a simple firmware flash!
BACK UP YOUR PHONE! ALL DATA WILL LIKELY BE WIPED!
You will need an SM-G998U/U1/W
Computer running Windows
USB-C Cable for your PC to Phone
This is only for SM-G998U/U1/W
Step 1:
Download the ROM of your choice. The firmware number does NOT need to match your phone, as long as you have an SM-G998U/U1/W
From each link, click the latest firmware in the list (what ever the top one is) and on the page that loads, click the blue button that says "Download from website"
(You can only download one in a 24 hour period so choose U1 or W wisely)
SM-G998U1 (U1 is unlocked, no carrier bloat, US radio bands)
SM-G998W (W is unlocked, no carrier bloat, Canadian radio bands)
The only main difference between the two is the Canadian W Firmware supports all radio bands aside from (n260, n261), the file size is a little bigger and will take up a fractionally larger amount of space on your phone as a result of also including all CSC's, but will allow your device to connect to any tower frequency with the correct SIM.
The U1 Firmware supports all US bands and works across all Canadian carriers, but does not have any Carrier CSC's as a result of the smaller file size.
Thanks to @milan03 for the info
Best measure is to use the W Firmware as it will be supported, but if you are positive of your carrier will work and bands are the same as US carriers, use the U1 to save some space.
Step 2:
Download Odin 3.14.4 and Samsung USB Drivers
Step 3:
Extract all of the .zip files that you have downloaded, and install the Samsung USB Driver
Step 4:
On your S21 Ultra, enter download mode by turning the phone completely off.
Once the phone is off, hold the volume up AND down at the same time, and without letting go of those buttons, plug a USB cable in from the computer to the phone
Do not let go of the volume buttons until the Download Mode screen is displayed.
Step 5:
Open Odin and make sure the S21 Ultra comes up as one of the COM ports
If it doesn't try rebooting your computer, and then connect your phone again
Step 6:
Click the BL Button, and select the BL file you extracted from the Firmware .zip
Click the AP Button, and select the AP file (This will take awhile, do not touch anything, don't even click your mouse or try to do anything else on your computer, it can crash, just wait, make a coffee or something, because depending on your computer specs, it can take up to 5 minutes to load that file
Click CP and add the CP file
Now this last part here, you have a choice, however I strongly recommend you do not choose the second option at this time, however you CAN, but you might face stability issues.
When clicking CSC, you can EITHER add the CSC file, which is what I recommend, OR you can add the HOME_CSC file.
The differences between these files is that the CSC file will wipe your phone, but this is recommended, because when you are switching firmware's from a different carrier build, which we are right now, you want to delete anything left over that could conflict with the new firmware being flashed, however, you CAN flash HOME_CSC which will keep all of your user data on the phone, but this could leave old firmware files behind that could cause stability issues with your phone, crashes, force close apps, or even boot loops.
It's recommended to ONLY use HOME_CSC when you are UPGRADING on the same build (eg, if you are on SM-G998W and UPGRADING to another SM-G998W firmware)
So if you are going from U/U1 to W, it's recommended to use CSC, if you are going from W to W, Home_CSC should be fine, if you are going from W to U1, you should use CSC.
Step 7:
Once you have made your choice of either CSC or HOME_CSC, you can now click Start and it will start flashing the new firmware.
This process will take a fair amount of time, go relax and enjoy that coffee you made while the AP file was loading.
Once the flash is done, it will say Pass in green, and your phone will reboot automatically into your new official carrier bloat free firmware.
If you picked CSC, you can now setup your phone just like a new phone and restore your backup, if you picked HOME_CSC, you should be at your lock screen, and the phone is ready to use.
Congratulation, you are now on the Official Samsung Firmware with no carrier bloat as if you bought the phone directly from Samsung.
Troubleshooting:
If you used CSC and the phone did not pass and says FAIL, try the flash again with HOME_CSC, once the flash passes, you should be back at the lock screen, go to settings, search for reset, and do a factory reset, wipe all data because something did not flash correctly the first time so you need to wipe the phone after the successful flash to guarantee no stability issues.
If you used HOME_CSC and the phone did not pass, use CSC and the phone will be wiped when it flashes, and you need to set up your phone like new and restore your backup during the setup screen.
If it still fails to flash both CSC and HOME_CSC, Download Mode probably timed out from your computer taking too long, at which point, you can try doing Step 6 BEFORE Step 5.
Turn your phone off completely, load all of the files into Odin, THEN enter Download Mode and immediately click Start to start the flash. This will give you a little more time for your computer to make the flash and hopefully download mode will not timeout, if it still fails, try a faster computer or a different/shorter USB cable.
If you are with Bell in Canada and you did not get the pre-order bundle promo E-voucher prompt from Samsung Members App, flashing the SM-G998W firmware linked above will fix this and you can redeem your e-voucher and get your headphones and smart tag.
This is a video I made on the S20 Ultra for flashing One UI 3.0 Beta/Stable, however the process is identical, just use the files from here instead of the ones linked in the video description
I will be replacing this video with a dedicated S21 tutorial once I have have finishing editing the new video, but for now this will give you an idea of how it works until 5:30 in the video, after that it's mostly related to One UI 3.0 Beta/Stable for the S20 so there's no need to watch further than that as the S21 would be done by that point in the video.
Thank you sir.
So will this trip KNOX? My phone should get here next week (AT&T), and one of the first things I always want to do is get rid of the bloat.

No problem with KNOX.
But majority of bloatwares are issued of CSC carrier brand and it is impossible to change csc without root or using samkey...
So this firmware will be like other versions with same samsung apps unless I'm wrong.
Thanks for the guide.
If I may, I'd like to post a correction on the state of the supported frequency bands on Canadian and the US firmware:
- The U1 firmware doesn't only support T-Mobile bands, it also fully supports AT&T and Verizon frequency bands, which includes their unique LTE carrier aggregation combinations as well as the 5G non-standalone combinations with n5 and mmWave. That's in addition to T-Mobile's combos with n71 and n41, in both non-standalone and standalone environment.
- At the same time the Canadian W firmware doesn't support all 5G bands, it completely disables mmWave (n260, n261), which means the US devices with this firmware won't be able to access this super-fast flavor of 5G on any US network. It also doesn't fully support all US 5G non-standalone combinations in FR1 (Sub-6 GHz) range.
Thanks again.

If you're running a multi csc firmware (the one's linked above) you can change your csc by opening the phone app and dialing *#272*YOUR IMEI NUMBER# and from there you can pick the firmware CSC and carrier CSC to be whatever preinstalled apps you want. The W firmware has all of the preinstalled which is why the file size is larger.
As for the Samsung bloat, they all come with it, but a lot of these should be able to be removed using ADB without root.
There are some ADB scripts around that some skilled people wrote for removing bloat apps in bulk through ADB without root.

Hello!
Thank for you posting this @bANONYMOUS. Question if I buy the the U1 model can I flash the W firmware? My father is in Canada and I'm getting an early Bday present for him. Making sure when he gets it, that it will have the correct bands for Rogers!
Is there any qualcomm firmware that has an FM radio app?
I purchased from the US and flashed the XAC firmware. The final result was XAC/XAC/XAA is that correct? I thought all blocs would be XAC.
Also, I wasn't sure if repartition should be checked or not so I unchecked it.
No VOLTE or WIFI calling on koodo.
I bricked my device today so I'm trying to flash stock OS.
I started flashing it in odin, but it seems it gets stuck on "<ID:0/010> vbmeta.img" for few minutes.
Not sure what is causing it, does anyone have any ideas?
Just tried this with u1. Failed each time
I'm trying to flash u1 onto TMB device. Keep getting failing with sha256 is invalid. Is there a modified odin 3.14.4 yet?

Well, based on what my unlocked note 9 has:
Under the phone app settings there should be a setting for caller id and spam protection
Under system settings in the accounts and backup section there is should be samsung cloud,
Under system settings in the connections section there should be call and messages continuity.
These are all options I have on my unlocked note 9, but not on VZW FW S21 Ultra
