Can I change China CSC to TGY CSC on G7810? - Samsung Galaxy S20 FE Questions & Answers

I have chinese version of G7810 S20FE 5G. I want to change it to TGY CSC as CHC version now isn't updating regularly.Is there any chance of brick? Will the device broke if i do that?

if the Hong Kong model is a 0 or O model than it'll work. you'll need a modded version of Odin.

What did I do wrong trying to change my CSC?

I received my international version of the N960F/DS. It had XEU firmware. I tried to install BTU firmware via Odin using a SamFirm BTU download and a UK Giffgaff SIM and selecting CSC, not Home_CSC. I still ended up with XEU.
1st question - am I likely to get Pie and other updates more quickly on BTU than XEU?
2nd question - how do I change from XEU to BTU? I think I saw that on previous Galaxies maybe you had to install a firmware not on the OXM multi CSC and then install BTU afterwards. Is that what I should have done? If so, what CSC do you suggest?
3rd question - should I just leave it alone?
TIA.

Use search instead of creating topics saves space
simply flash desired firmware wont work, you will need to flash combination file first before that.
follow above comment will work

Flashing firmware from different CSC (but same multi-CSC)

Hi! My Galaxy S20 FE is the 4G Snapdragon variant (SM-G780G). The Android 12 update is not yet out for my CSC (GLB), but it has been released for Malaysia (XME). Seeing as they're both part of the larger OLM multi-CSC, can I flash the Malaysian firmware through Odin and still retain my GLB CSC (no factory reset)?
yes you can if you A) use only BL, AP and CP from OneUI 4
and use HOME_CSC from your own last OneUI 3.1 firmware (they share the same bootloader binary version number). your CSC will not change then. many have tested this and said it works, however some say it may cause OTA updates to stop working. if that's true downloading the firmware for GLB once it's available would fix that (with you flashing it again with the HOME_CSC).
B) you could flash it all from XME using HOME_CSC, I've only heard from one person saying this worked, honestly I can't remember if his CSC stayed as it started out, the rom worked though.

Change CSC from LUX to DBT
Can I change my CSC from LUX to DBT by flashing the DBT firmware (minus the HOME_CSC, so i keep my data) ? I've just ordered credits from Sammkey but I'm wondering what that is even needed if a flash via Odin will also do the trick. I want to...

got an update to the one ui 4.1
but during the update it was written that I was updating to one ui 4 but it's already installed
after updating version in settings is 4.1 but nothing has changed

I have an ATL device (Vodafone Spain). Apart from the one Vodafone bloatware app that I uninstall via adb, I can use my Magenta Austria SIM just fine. Everything works as intended and I assume this is due to the OXM firmware. So if you don't miss any features, I personally wouldn't bother changing the CSC
If XEH and DBT share the same multi OXM firmware, their firmware is exactly the same. Meaning flashing the DBT firmware will do nothing as it is the same one that XEH uses. The CSC will only change by that method, if you flash a firmware that doesn't have your current CSC included

Question S21 Ultra Software Update problem

Hello guys, I need your help. I bought the phone in the US and moved to country Georgia. As I understand because the CSC code changed I can't update the software. My only option is to flash it via Odin. Following the youtube guide, I downloaded Frija and Odin apps, but I am stuck in the Frija app because don't know which CSC code I should provide alongside my phone model to download the firmware. Could you clarify this matter for me? Thank you in advance.

Thank you for reaching out. After a whole day of digging into the matter I solved the issue. I changed CSC code few times, suprisingly which didn't work. Then as someone pointed out that model of my phone was for Verizon, I changed CSC to verizon branded phone one and viola it did the trick. Although, after all the updates csc stayed same and it brought some Verizon bloatware and verizon start animation during bootup. Do you have any info as to should I change csc back to XAA or let it stay as it is? Note: I bought phone as an unlocked one and it's unlocked but still it was Verizon branded one. Would that cause any problems?
Download SM-G998U1 (XAA) in sammobile.com. Flash it using odin patched (Regular odin will not work)

I have zero knowledge of flashing modding firmwares. Can I ask you why you are suggesting this, is Verizon version of the firmware inferior in any way?

Verizon firmware comes with verizon apps. You dont need those. By flashing U1 firmware.
Then i would say youtube is your bestfriend. You will need samsung drivers to be installed in your pc. patched odin, then the firmware from sammobile.
1. Latest XAA Firmware (sammobile)
2. Samsung Drivers (Personal Mirror)
3. Patched Odin (Personal Mirror)
4. Youtube Guide (skip frija since you already download the firmware in sammobile)
Good luck.
gujikoo​if your device is unlocked you can stay with XAA CSC ( U1 firmware ) and you will not have Verizon bloatwares
​gidzdlcrz​3. Patched Odin (Personal Mirror)
Caution #1 - There are many stock/mod/patch copies floating around the internet with redirected links and other misleading claims and changes. The XDA links below are the only source for clean originals and the original 3B files.

Trasform g9730 into g973u1

Hi, i was wondering if i can transform my snapdragon G9730 into the american version G973U1 (also snapdragon) just flashing the the original g973u1 firmware. I d like to do that because the american firmware is better optimized for the network where i live. if is not possible to flash all the firmware, could i flash only the CP file from the american version g973u1 togheter with BL,AP and CSC from my g9730 firmware?

The only firmware you can use G973U1 firmware on is a G973U or U1.
NEVER flash firmware for a different model number on your device. You will render your device completely inoperative. Only use G973F firmware on a G973F, G9730 firmware on a 9730, etc.
If you wanted to use the G973U1 AP or CSC, that might be possible and easily fixed, but since the CP file is your modem firmware, you could cause serious damage or problems by using one not intended for your device.

So in both the cases there is the risk of brick the device? without the opportunity to flash the original firmware back?
