Hi guys so I bought an overseas S21 Ultra Exynos variant and brought it to my home country. While the 272 method works, I was wondering if flashing my home country's official firmware would cause the AID (third CSC code on software info) to change to the flashed firmware or not. If not, would it change if I flash a different none multi-csc variant firmware first before going back to multi-csc?
Thanks!

I've got a Telstra-branded S8+ (code TEL according to Sammobile) and I want to flash regular unbranded firmware onto it but I'm a little confused by all this talk of CSCs and so on. Is it safe to download the Australia (XSA) firmware and simply flash the HOME_CSC file over the top of what's already there, or is there more to it than that? Do I need to worry about this tripping Knox/breaking Safetynet/disabling OTAs/etc?
I have had no issues with flashing XSA on my Singapore model Note 8. As long as it is the official firmware this will not trip Knox.
Though your original CSC will appear in the Software Information as the third CSC. Mine currently shows XSA/XSA/XSP (XSP is Singapore)
I've attempted to searched up the different kinds of firmware for this model phone and as far as I'm aware for the F series (international) versions of the S10 it is either for UK, Asia, or Europe
I have a Galaxy S10 G973F/DS and when I got it the stock firmware on it was G973FXXU1ASAT. Although reading further I've seen other firmwares ending in ASBA and ASC8.
I guess this means the Dual Sim model can only come from the asia model according to this chart

I've been attempting to add TWRP onto my phone using this guide and I've been having difficulty with it and I dont know if the firmware I downloaded is not compatible with it. So if anyone else has any suggestions on firmware I'd like to know.

ASAT, ASBA, ASC8 are all different releases of the Firmware.... They are released in order Alpha and Numerically, So ASAT is the Oldest you named and ASC8 is the Newest... The most important is that the Model and bootloader portion of the firmware name is correct. G973FXXU1.... Then you have to find THAT EXACT FIRMWARE for your Carrier. Which like I said is NOT the ASC8 part(thats just the firmware release). It will be identified with a CSC code like "XAA"
So, at the end, you want the G973FXXU1ASC8 (or newer now) Firmware for whatever carrier you have...
Today, I would flash G973FXXU3ASIG for whatever COUNTRY/Carrier you need...
I have Note 9 with Indonesian Firmware and im thinking to flash Australian firmware. I checked the phone model number and its exactly same (N960F/DS). what im worried about is
1. if I flash Australian firmware, would I keep getting the notification if theres any patch / software update or I'll have to find the update manually?
2. if I still get the patch / software update notification, would I get the Australian ver. or the original (Indonesian) ver? (im afraid if its different)
3. Would Samsung Pay System work in Australian firmware? ( I read if you flash different firmware to the phone model, some functions wont work including Samsung Pay System).
Any help would greatly appreciated
1. if I flash Australian firmware, would I keep getting the notification if theres any patch / software update or I'll have to find the update manually?
if you flash the firmware with the Austrailian CSC, you will only get updates from carriers within that CSC in accordance with what network your SIM is connecting to. Only time you flash them manually is if you have an aftermarket recovery such as TWRP
2. if I still get the patch / software update notification, would I get the Australian ver. or the original (Indonesian) ver? (im afraid if its different)
see above
3. Would Samsung Pay System work in Australian firmware? ( I read if you flash different firmware to the phone model, some functions wont work including Samsung Pay System).
samsung pay doesnt work in certain countries period. that might be what youve been seeing

I tried to flash with Global Australian CSC (not for any specific carrier) and I was be able to get update OTA. Now, the problem is after I flashed Au firmware (incl, BL, AP, CP, CSC) with Odin3B, somehow the service provider software has changed to AUT/AUT/XID while previously XID/XID/XID which is weird. I tried flash using HOME CSC file and couple times I re-download the firmware and flashed other unlocked au firmwares (with android 10 version) it still gave me AUT (Switzerland) instead of XSA (Australia).
Any idea why?
I bought myself a supposedly brand-new, in-box SM-N960F/DS (so this is the dual-SIM version of the Note 9) using the Exynos 9810 from an online retailer in SEA. As it turns out, the phone has an Android patch level of Nov 2019, so I wanted to update it to the latest Android version available for the phone (Nov 2021). And that's when I found out that my set was an imported set from some other country in SEA, and about Samsung's *wonderful* CSC region-locking 'feature'.
Okay, so basically, I'm going to try to go to a Samsung service centre to see if they can change the CSC on my new phone so that I can receive OTA updates. Failing which, and this is the reason I am making this post, I would like to change the CSC myself and update the phone - using Odin, if I have to.
The phone is using what I believe to be stock ROM with a baseband version of N960FXXS4CSJ1, and a Service provider SW ver. of SAOMC_SM-N960F_OXM_XXV_PP_0010. From what I was able to gather, this means that I have a multi-CSC (OXM) firmware, but it is currently set to generic Vietnam (XXV). The two CSC combinations currently reported are XXV/XME,XXV/SKC.
Now, I have tried to change the CSC by using Google Phone and dialling the *#*#27262826#*#*, and that didn't work for whatever reason. I tried the *#272*IMEI#, and that didn't work either, for whatever reason. I guess I will have to flash a new firmware in myself.
I currently have downloaded via Bifrost both the XXV and the XME latest firmware versions (Security level Nov 2021 as of now). I do not intend to root the phone or anything like that (that said, AIDA64 reports that my device is rooted, for whatever reason). I have also downloaded the Samsung USB drivers for Windows and Odin 3.14.1 (both patched and unpatched). I don't know where I can get the OXM version of the firmware, which would be best, because dual-SIM allows me to slot in an Aussie SIM when I do travel over there.
I would greatly appreciate it if I could be advised as to whether I can simply flash the XME firmware and then receive OTA updates thereafter, or do I flash the XXV firmware and keep a watchout for future updates manually. Or, indeed, what my other options are. Step-by-step instructions would be nice, although I intend on following the tutorial as listed here: https://www.xda-developers.com/how-to-update-samsung-galaxy-smartphone/
Hopefully, I will retain the dual-SIM functionality, along with VoLTE, Wi-Fi Calling, Call recording, and so on and so forth.
Thanks in advance!
just download latest firmware for your phone from here https://www.sammobile.com/firmwares/ (you can select country and operator)
put your phone on download mode and flash with odin. Done!
Does that mean I can disregard what the current CSC is, and I can choose whichever CSC (country) I am currently in regardless of what the Note 9 is set to at the moment?
Greetings all; would appreciate any insights as to whether it will be safe to flash the XME or XXV firmware into my device. I'm more than happy to provide additional information if that would help.
I have a recently purchased galaxy s21 ultra 5G SM-G998U and Im currently stuck on Sept 2022 patch with A12. CSC is XAA/XAA/XAA/ATT. I'm from Kenya and since this is a US-based model how do I go about accessing the updates, do I flash the firmware to the one in my region or the one in the US
Should be fine, as long as the CSC you want to use isn't included in the firmware you're flashing. You must flash the firmware that corresponds to your model number - meaning you can't flash G998B, G998W, or G998N firmware.
You'll need to use the CSC.tar, not HOME_CSC.tar, because you'll need a factory reset.
So I use a SM-G998U or U1 firmware?
