[Q] NEED ADVICE on flashing stock roms

I have an Orange branded phone. Its build number is GINGERBREAD.BVJVC. I heard that you could only flash stock roms that is from the same region. Apparently Europe is XXJV(one more random letter). But mine starts with BV. is this because it is Orange's rom? Or does this not matter and can i flash with any rom including branded ones even with a different firmware (basically different everything).
On the site sammobile(.)com can find your correct branded firmware.
thank alot

Wifi Calling

Hi.
I've just bought a XZ3 specifically to use Vodafones UK Wifi Calling, however cant access it.
Vodafone provided instructions ie phone - three dots - settings but it isnt there.
I've read online that I need to change the firmware but not sure which one to switch to.
The current model is a H9493 which seems to be Asian.
Any ideas guys?
Thanks

Xperifirm, newflasher (both in xda)
Install firmware of your region.
And make sure you use the dual/single sim version corresponding to your hardware.

Correct, Xperia's require regional firmware to gain use of VoLTE and VoWIFI.
You can use ANY of the H8416 or H9436 (single sim) that is UK region to flash with.
The H9493 is specific to Hong Kong, Taiwan and China, Easily Identified by the 6GB RAM.
I have the H9493 and am currently running US region H8416 with no problems.

What is the difference between ASAT and ASAB firmware? I need help picking a firmware

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
https://www.techwalls.com/samsung-galaxy-s10-model-number-sm-g973-differences/
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...

N960F/DS Swap firmware region

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?
