Is there any way to do this currently and get BTU CSC, I've searched here and the web and came up blank so far
Depends what CSC you're on now, if it's a MultiCSC that already contains BTU, then no not easily, if at all
If it's a single CSC then just flashing the BTU CSC (Using CSC not HOME_CSC) should change it (Remove SIM first)
(Optional)
Go into developer options and select OEM-Unlock option
WARNING: this will perform a factory reset and wipe everything your internal phone memory
(Required)
Download the latest FW for your S9 (SM-G960F / BTU)
(I use the PC app called Samfirm, which downloads the latest official FW package in 5-10 mins)
Download the latest Odin package, (3.13.1 or later)
Select all the individual flash files but select CSC_ file and not the HOME_CSC file (this is important for de-branding)
After flashing your phone perform another factory reset then boot up as BTU / unbranded.
(Optional)
Go back into Developer Options and disable OEM-Unlock (yet another factory reset)
I performed the above process at the weekend to change from H3G (Three UK) branded firmware to BTU and today I received the automatic OTA update that was released yesterday for BTU, so you still get updates
Hope you find this info useful?
EDIT: I am thinking you might be able to do the de brand without toggling OEM Unlock off and on - saving you 2 factory resets. Let me know if that works

I am creating this guide to convert convert the G930VL to G930V since i cant find a guide for android 7.0 and The G930VL firmware is no ware to be found. I have been a long time member and have flashed many roms on phones and normaly dont find a need to post but since i could not find much on the internet i decided to make a step by step guide.
I take no credit for creating any of the tools used in this guide as i was not the creator. I have only figured out the way to get the G930V firmware on to the phone.
I am not responsible for any bricked devices
You must have usb drivers installed
Tools:
SamFirm V0.3.6 (as of writing) https://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647

Steps:
1: Download SamFirm, Odin PrinceComsy, and the PIT file.
2: Extract and Run SamFirm ( Samfirm requires Microsoft Visual C++ 2008 Redistributable Package (x86) and Microsoft Visual C++ 2010 Redistributable Package (x86) can be found on microsofts website if you recieve an error when searching for firmware) .
3:In the firmware info box under Model enter SM-G930V and Region enter VZW. Make sure Auto is checked. and click check Update.
4: Next in the download box to the right make sure both CRC32 and Decrypt automaticly are both checked and click download. A save box will appear and save to where you need.
5: Once it is done Downloading and Decrypting navigate to where you saved the file and unzip the file. There are 5 files inside the zip (AP, BL, CP, CSC, CSC_HOME)
6: extract and open Odin PrinceComsy and click each one of the BL, AP,CP,CSC radio buttons and choose the matching file from the fimware unziped in Step 5. FOR CSC BUTTON FILE YOU MUST CHOOSE HOME_CSC FILE (TO KEEP YOUR DATA) OR CSC FILE (TO ERASE YOUR DATA). DO NOT CLICK START!!!!!
7:Extract the PIT file downloaded.
8: In odin click on the PIT tab and browse and select the file extracted in Step 7. DO NOT CLICK START!!!!!
9: Next go to the options tab and make sure Auto reboot, Re-Partition, and F. Reset Time are all checked.
10: Click Start and the phone will flash the files and reboot into recovery and finish installing and reboot a few times. wile rebooting it will boot back into recovery and say erasing. then the next reboot it will boot into the G930V firmware.
I hope this help Some people out there. If you have any questions post them below or PM me.

Thanks, your guide help me flash my phone and everything works except for sending text messages (and since smsc isn't working my voicemail doesn't either). Did you have this issue as well? My smsc is in the messaging app but it doesn't work. Receiving texts, Sending/receiving MMS, calls, 4g data all work.

Double check your apn settings. Sometimes they get muddled. Also, my experience with this is that you have to make a call to get texts to work. I jest updated to oreo using jkruse post and it works much better than nougat. My apn was wrong and just changing the name to TRACFONE.VZWENTP fixed everything

So my friend tried rooting his phone (VL model) and it's bricked. It has a boot loop with the installing system firmware screen. But I can boot into Odin download mode. I tried using this method and picking both CSC and home CSC. On the CSC one it will fail at emmc_appsboot.mbn.lz4 after the "single download" line.
The Home CSC, it will reboot after the RQT_CLOSE and RES OK and says pass for for set partitions, but when it reboots it goes to the installing system firmware bootloop
Any suggestions? He can't afford a new phone. And I'd love to help him fix it!
I have a copy of the SM-G930VL firmware.

I think i bricked my SM-G930VL from straight talk, it boots up but it immediately reboots after not even 10 seconds of being booted up. i think it was because i rooted and google apps mostly did not load, they had a loading circle but it never loaded so i decided i would try and go into recovery mode and clear/wipe the cache partition. im not quite sure if thats why i cant fully boot past the lockscreen, i tried a factory reset after attempting to boot into safe mode several times but it continues to reboot after the starting android screen, wont even let me setup the phone now.. its very frustrating and if the stock firmware will work, do you still have it? or would i need to try something else?
This method bricked my Straight Talk S7 by leaving it in a recovery loop. I was able to get it into download mode, then installing SM-G930VL Tracfone firmware with Android 6.0 using Odin PrinceComsy (no PIT file). Then, once it was working, I did official software updates through system update to get it up to Android 7.0. I originally had Android 8.0 before brick, but it is still doing updates after every install, so I'll check in if I was able to get it back to how it was before. I suspect that the PIT file used in this guide may be what is causing the recovery loop. I will try the SM-G930V conversion without it to see what happens. My ultimate goal here is to get my Straight Talk S7 rooted.
can you get me the link to SM-G930VL Tracfone firmware you used please
Hello all,
Before my Tab S4's (ZTO original, Brazil open) Pie 9.0 firmware was out, I flashed the official XEF (France open) FW for the sake of previewing One UI and when my tablet's official firmware came out, flashed it on as well.
Now my Tab S4's CSC is stuck in CHO (Chile open), I tried the SIM trick, didn't work. Both times the CSC file, not the HOME_CSC file, was flashed.
According to Phone Info *SAM*, Original CSC is blank, Firmware CSC is CHO, Active CSC is CHO, even though my SIM is brazilian, same region as the tablet's.
Product Code (SM-T835...<REGION>) has CHO as the region, not ZTO. When it was flashed with the XEF firmware, Product Code had XEF instead. That is, the Product Code changes to reflect the DEFAULT CSC for the Multi-CSC.
I have flashed the official ZTO firmware (Multi-CSC) with the SIM in, out and performed factory resets with and without the SIM.
Am I doing something wrong, or is it a firmware issue?
REVERTED back to ZTO: success!!!
As a matter of fact, at least in the case of Galaxy Tab S4 (SM-T835), it's now possible to set up ANY CSC as the Country CSC with current firmware/combination firmware. Knox NOT tripped!
I'M NOT RESPONSIBLE FOR WHATEVER DAMAGE RESULTS FROM THE FOLLOWING STEPS.
Steps I took to achieve this:
0. Have latest ODIN and PLATFORM_TOOLS installed on a Windows PC; know basic ODIN flashing procedures.
1. Flash the latest firmware you want on the tablet using ODIN (BL, AP, CP and CSC, using standard CSC file, not HOME_CSC file).
2. Flash the combination file (I used the one with PDA version T845XXU2ASA2, see link) in AP.
3. After the tablet reboots to the main screen, TAP ALL CIRCLED LETTERS FROM LEFT TO RIGHT, in rapid succession.
4. A message telling that you've become a tester pops up briefly at the bottom of the screen.
5. Go to the APPS tab, now you'll see something that wouldn't be there without step 4: a TERMINAL app. Execute.
6. Type "echo -n XXX > /efs/imei/mps_code.dat" (without quotes), where XXX is your desired CSC (must exist in the desired ROM to be installed).
7. Press the power button until the tablet shuts down.
8. Turn the tablet on again.
9. From the command prompt, execute "adb reboot downloader".
10. Flash your firmware (BL, AP, CP, CSC) again. It MUST contain the CSC you wrote in mps_code.dat.
Presto!
I tried to root my phone, it went wrong and it is stuck in download mode. Most tutorials say to download the stock firmware and load it in odin at the " AP " box, but the download file from sammobile.com has 5 files and the website says to load each one in the right box... so which one do i do ? (When i tried to root my phone i loaded only a AP file)

CSC vs. Home_CSC, the difference
Upon downloading the full firmware on your Samsung gadget, you can see the five different separate files. They together form a file on the phone. They are tagged as
BL (Bloatware),
CSC and Home_CSC,
AP (Kernel, Vendor and System information),
CP (Modem)
In this post, generally, the CSC and the Home_CSC are focused. They are available for different purposes despite there is not much difference in the two when compared with each other. You can select it depending on one prime factor.
CSC- When you choose to flash this file in your Samsung device, it will erase everything in it, and your data will be gone before making the changes to take place in your Samsung device
Home_CSC- This is a file that can be selected if you really don’t want to lose your phone data and any of its important settings. You can find it the same, even after flashing the same.
CSC is the option that is generally recommended. This is because it confirms the most appropriate updates for your phone. On the other hand, Home_CSC instruct Odin to don’t cause any change to the phone settings and the data stored while reinstalling an update such as a security patch.

Must Have An Unlocked Bootloader To Do This!
This An odin tar file I have created to flash along with stock odin firmware to automatically install TWRP recovery along with Disable VBMETA image. The tar file will also automatically install magisk root along with remove force encryption and patch bluetooth library file. It will also patch safetynet. No flashing of zips is required
Info For Bootloader Unlocks Can Be Found In Post 2
I Do Not Recommend Mixing Bit 5 With Higher Firmware!!!!
Unless Using Bit Safe Firmware That Is Patched
Downloads
SM-N970U/U1/W- Model
USERDATA_AIO_N970_FORCE_WIPE_10_10_21.tar.md5 --Use on android 10 or 11
This will force a wipe of data no mater what.
Full Odin 3.1.1 Bit1 Safe Firmware
N970USQS7FUH3_BIT5_SAFE.7z
This are odin files and will safely update all image files too bit 7 and keep bit 5 bootloaders. Unfortunately this will wipe data this is beyond my control as it seems to be a side affect of mixing firmware it causes data not to mount and therefore my AIO will format it. This is full firmware with USERDATA_AIO. This will put you on U firmware. Before flashing I recommend removing your google account and make sure in download mode you are not frp locked
If above USERDATA_AIO_N970_FORCE_WIPE_08_30_21.tar.md5 is newer than the one in this zip use the newer one from above

Applicable Models:
All Exynos models including but not limited to:
SM-G980F or SM-G980F/DS (S20)
SM-G981B or SM-G981B/DS (S20)
SM-G985F or SM-G985F/DS (S20+)
SM-G986B or SM-G986B/DS (S20+)
SM-G988B or SM-G988B/DS (S20 Ultra)
All BL-unlockable Snapdragon models including but not limited to:
SM-G9810 (S20, Hong Kong, Taiwan, China mainland)
SM-G9860 (S20+, Hong Kong, Taiwan, China mainland)
SM-G9880 (S20 Ultra, Hong Kong, Taiwan, China mainland)
SM-G981N (S20, Korea)
SM-G986N (S20+, Korea)
SM-G988N (S20 Ultra, Korea)
Japanese model (SC-*) also use Snapdragon but I can't not confirm that its bootloader is unlockable.
It is known that bootloader can NOT be unlocked on U.S. models (U/U1) .
Frequently used key combinations of S20 series:
FORCE REBOOT: Hold "Volume Down" and "Bixby/Power" button.
DOWNLOAD MODE: With the phone off, hold "Volume Down" and "Volume Up" button, connect your phone to a computer via a cable. Release the buttons after you see the "Warning" screen and then press "Volume Up"
RECOVERY MODE: With the phone off, hold "Volume Up" and "Bixby/Power" button.
Some facts:
1. S20 series uses dynamic partition which means there is only one "super" partition (instead of "system", "vendor", "product").
3. S20 series uses A-only partition which means there is only one set of system partition.
3. S20 series uses 2 stage init (2SI).
4. KNOX will be tripped after you flash a custom image. As a result, Samsung Pay and Secure Folder will become permanently (even after restore to stock firmware) unusable and your warranty may be voided. However, many jurisdictions including the European Union has law mandating manufacturer to provide hardware warranty even if user modifies the software.
5. Samsung devices are almost impossible to hard brick (render the device unusable without a hardware-level repair) as critical sections including the bootloader are well-protected. However, if you do things incorrectly, you may soft brick your phone, but that can usually be resolved by resetting to factory settings (wipe data and cache) or restoring to stock firmware (check out Stage 4).
Tools needed:
On your computer:
1. Odin 3.14.4 or newer
2. Samsung Android USB driver
3. SamFirm or other tools/websites to download official firmwares
4. Android Verified Boot Metadata Image with verification disabled (vbmeta_disabled.tar)
On your device:
1. Magisk Manager
Stage 1: Know your model and carrier code (CSC)
1. Open "Settings"
2. Go to "About phone" -> "Software information"
3. Pay attention to "Service provider SW ver."
4. Starting with "SM-", for example "SM-G9810", that's the model of your phone.
5. Immediately after that, there are two 3-letter code, for example "OZL_CHC". The second 3-letter code "CHC" is your CSC.
6. Remember your model and CSC.
View attachment 4990047
Stage 2: Unlock the bootloader
WARNING: ALL data on your device, including apps, settings and files in internal storage, will be lost. You do not need to repeat this if you didn't re-lock your bootloader.
1. Open "Settings"
2. Turn on "Developer mode" by going to "About phone" -> "Software information" and pressing "Build number" for several times.
3. Go to main menu of "Settings" and at the bottom you will find "Developer options"
4. Go to "Developer options". You will find a toggle "OEM unlocking". Turn it on.
View attachment 4990049
5. Skip to step 8 if your device reboots to "Unlock bootloader?" screen. Make sure the toggle is on and then turn off your phone.
6. With the phone off, hold "Volume Down" and "Volume Up" button, connect your phone to a computer via a cable. (don't use charging only cables)
7. Release the buttons after you see the "Warning" screen. Then, hold the "Volume Up" button.
8. You will see "Unlock bootloader?" screen. Proceed and unlock your bootloader by pressing "Volume Up" button.
9. Your device will be reset to factory settings. Proceed with the Setup Wizard. Only connect to network via Wi-Fi or cellular and skip everything else. (to save time as data will be cleared again later.)
10. Repeat step 1-4 to validate that "OEM Unlocking" is on. If it is not, turn it on.
11. Repeat step 6.
12. Release the buttons after you see the "Warning" screen. This time, press (not hold) the "Volume Up" button.
13. You will see "Downloading" screen. On the top left, there are some important info.
14. Pay attention to "OEM LOCK" and "REACTIVATION LOCK". If both of them are "OFF", you have unlocked the bootloader.
View attachment 4990051
Stage 3: Disable Android Verified Boot
1. Reboot to DOWNLOAD mode. If you are already in the download mode, skip to step 2.
2. Download Odin 3.14.4 or newer and make sure Samsung USB drivers are installed.
3. Open Odin and put the vbmeta_disabled.tar into USERDATA slot and click "Start"
4. Your device will reboot but it will not boot into system as vbmeta signature has changed.
5. Your device will reboot into RECOVERY mode automatically and prompt "You have to reset your device to factory settings". Use "Volume Up" or "Volume Down" button to move and "Power/Bixby" button to select. Confirm and reset the device to factory settings.
6. This is the last time the data on the device has to be cleared. Afterwards, if you don't re-lock bootloader or re-enable the Android Verified Boot, you will not lose your data. Be aware, a stock firmware package contains a Android Verified Boot Metadata Image (vbmeta.img) with verifications enabled. You will need to flash the vbmeta_disable image (put into USERDATA slot) along with the stock firmware (use BL, AP, CP, CSC slots) to make sure AVB is not re-enabled and the data is preserved.
View attachment 4990053
With bootloader unlocked and AVB disabled, it is now possible to boot modified images on the device.
If a recovery is available and you don't want to go through the process of downloading official firmware, go to #2.
You can also download a KERNEL TAR archive of your version here:
Exynos: https://github.com/jesec/proprietary_vendor_samsung_xyzs/releases
Snapdragon: https://github.com/jesec/proprietary_vendor_samsung_xyzq/releases
and then skip to Step 6.
Stage 4: Obtain the official firmware and upgrade
1. Open SamFirm
2. Type in your model and your region (CSC) and click "Check Update"
3. "Download" and you will get a zip file.
View attachment 4990061
4. Extract it and you will get 5 files (AP, BL, CP, CSC and HOME_CSC). All files are in tar format and can be opened by 7-Zip, WinRAR or other software.
5. Check the version code, for example (G9810ZCU1ATD1). The last 4 letters (ATD1) indicates the version of the firmware. If the version is the same as your current firmware, skip to Stage 5.
Your data will be preserved if you do it right but it is good to have a backup.
6. Open Odin on your computer and reboot your device to DOWNLOAD mode.
7. Put AP, BL, CP files in their Odin slots. It takes time to verify the firmware so be patient.
8. Put HOME_CSC file in CSC slot. Be careful here. Unlike AP, BL, CP slots, you should NOT use CSC file for CSC slot. Instead, you should use HOME_CSC file. CSC file contains partition table (PIT) which will erase all your data.
9. Put vbmeta_disabled file in USERDATA slot so AVB remains disabled and your data preserved.
10. Click "Start" and wait for it to finish. Allow the device to boot into system to complete the upgrade process. Do NOT interrupt/disconnect phones/hold button. It needs to complete the process without interruption or strange BUGs may appear.
View attachment 4990063
Stage 5: Extract boot (kernel) image from firmware
If you are having trouble creating tar file, you can skip to Stage 6. (NOT RECOMMENDED as AP is basically full system image. It is huge (takes long time to flash/process) and Magisk may misbehave.)
1. Extract boot.img.lz4 from the AP file.
2. Use 7-Zip to create a tar archive which contains boot.img.lz4 only. (or "tar cvf boot.tar boot.img.lz4")
View attachment 4990065View attachment 4990067View attachment 4990069View attachment 4990071
Stage 6: Patch the boot (Kernel) image via Magisk
1. Transfer the tar archive (or the AP file if you skipped stage 5) to your phone.
2. Open Magisk Manager.
3. Click top-right "Install" button
4. Make sure "Recovery Mode" is off in Options.
5. Click "Next" and select "Select and Patch a File" in Method.
6. Select the file you transferred to your phone in step 1.
7. Click "Next" and "LET'S GO".
View attachment 4999117View attachment 4990073View attachment 4990075View attachment 4990079View attachment 4999119
