[Q] Possible to change region completely in SM-G920i?

First of all, sorry if this has been answered here, I simply can't find a definitive answer for our S6, let me explain better.
As you may know, I'm not a newbie here or in other forums, I've rooted most of my phones (Not this one) and have installed custom roms dozens of times to all of them, BUT, I'm definitely a newbie about what I need here, I'm trying to see if I can change my SM-G920i region from XSA (Australia) to any other one, India in this case. I have read tons of threads and posts and that's what is confusing me, in some threads there are people saying that they did it and is working great, in that same threads there are people saying that they did it but Knox got tripped, there are others that say that the device is soft bricked and others are saying that they have read somewhere that changing the CSC from it's original one may brake future Samsung pay.
So, this phone is paid by my office, they allow me to do what I want to it while I'm able to just put it back as it came from factory, so that means that I can root it if it doesn't trip Knox, that I can install anything while I can simply go back anytime they need me to, and obviously, Samsung pay works when it finally comes. With this in mind, can somebody answer me a couple of questions?
1-) I know it's possible to do it, but is it true that by doing this I'll have Samsung pay issues? I doubt that knox will be tripped if I do it with odin, but besides knox, is there any possibility that Samsung Pay will not work in certain regions (India in this case) and that's why some are saying that it will break it?
2-) If I download the firmware and flash it via Odin, I'm reading that it won't brick the phone is done via Odin, but in worst case scenario I assume that I can always go back to original one and it gets factory reset, am I right?
3-) If I flash it correctly as I expect an it doesn't brick, does this means that it will change PDA and CSC versions all together, that it will basically become a device from the new flashed region? So if I flash the India one to my XSA (Australia) now it will work completely as an India device and should get future OTA like the rest?
Again, sorry if this has been asked and answered but going back a lot of pages here can't give me definitive answer, thanks in advance for those of you kind enough to answer to this.

Thanks.
In another thread that I have posted (Brazilian one) I was replied to, so because of that I decided to do it, so far everything is working great as expected. Mine was an Australian baseband (XSA), only thing you I noticed is that when I connect it to Smart Switch app for PC or MAC it will still detects the Original CSC, I was curious about it and installed Phone info apk and it shows correctly the information, both PDA and CSC are now from India but it shows that the Original CSC was XSA (In my case), Firmware's CSC code is INU (India) and Active CSC code it says XSA/INU, so I'm assuming that it's showing multiple CSC.
Does somebody know if having the Active CSC showing XSA/INU causes future OTA issues?

After flashing a ROM its good practice to go to recovery mode and do a full wipe of cache and full reset to change CSC to the default of the ROM you flashed.

Well, in that case I think I will pass for now, as I did a Full wipe cache and Full reset before the Flash but just did a Wipe cache after I flashed it.
The issue is that I basically just finish setting everything back as it was before (about 3 hours and I still haven't set my Contacts Ringtones and Accounts links) so begin again it's a PITA. Once I finish this I'll do a full nandroid backup to have everything as I want, but if I do the Wipe Data/Full Reset and then restore from the Full backup, does this put everything as it was including CSC again? I've been always confused about how deep this restore goes in the system files. Do you know about it?
Thanks.

Try restoring from your backup after the full wipe from recovery. If everything works then you should be ok. Otherwise start from scratch and reinstall everything one by one.

Will try that later today, thanks.

Goodluck.

I tried that and nothing, still the same, then I decided to remove the Re-activation Lock in Find My Mobile settings, and after that and enter to recovery mode, it changed the CSC to India, so for those of you with same issues, remember about Re-activation lock.
Thanks for your help.

Did you have a SIM card inserted when you flashed your ROM with removed reactivation lock?

I had the SIM card on the phone today all the time as I forgot to bring with me the SIM removal tool and didn't have anything to open the Sim card tray, but last night I didn't have the Sim card installed when I flashed the ROM.
So today after I did the Wipe cache Partition and Data and saw that it still had the same issue, I flashed a UK ROM into a SM-G925f that had some African country ROM (have never heard of it before in my life but for the name it sounded like an African country), anyways I did that and everything went great, so that's when I thought what was different between the devices and then I remember that I had turned on the Reactivation lock in my S6 and not in the S6 Edge, so I turned it off, then went to Recovery mode and for my surprise the CSC was already changed without any other reset or anything.

can you post a screen of CSC page of Phone ** info ** just for reference?
I see you said that CSC changed to India, but Active CSC or also Original CSC?
What I mean is that, now I have a S6 which has Original, Active CSC as MRU...I'd like to put a European fw on it since I'm based in Europe (got this Middle East / Africa phone just because Dual sim it's not available in europe) but I'm in doubt if putting an european fw will still show that CSC has changed from original one and maybe OTA updates won't work.
thanks

Changing csc!!!
I succesfully installed a G920I indian INU rom in my device which had a XSA rom but when i go to recovery it still shows as XSA ....How do i change that to INU?

Hi i am using a galaxy s6edge+ and i am really struggling with the region lock. I have tried a few options of the factory full reset changing the Apn's to the ones needed and using different sim cards.when it used to go into emergency mode "h+" now it won't connect to any internet at all. Can i possibly have any basic assistance with the rom and resetting options to change the csc when i do a hard reset the csc says it's 'multi'. what does that mean? Any region unlocking help would be appreciated so much!
Thanks guys

network locked s10 5G

purchasing a korean phone (in my case s10 5G U+) sim unlocked, the sim card was working good, after updating to the latest march update the sim worked for about one hour then a crossed circle appeared on the top. and no sim card can be read.
what does it mean ? what should I do ?
is it locked or a software issue ?

I suggest adding the device model to the thread title.

I don't know if you've already tried this but, try backing up the data that you want to save from your device, then boot into to recovery and choose factory reset, when the factory reset finishes, wipe the cache partition while in recovery then reboot the device.
Contact customer support for your mobile carrier and tell them that you lost service after the update was applied, then see if there is anything they can do from within their system to restore your cellular/network connection. If they mention sending you a new SIM, tell them no and that you will try to fix it first and then if it doesn't work you will accept a new SIM from them. Try finding a different solution before you resort to getting a new SIM because the issue might not even be the SIM but it's worth trying to see if they can do anything before you start trying to find software/flashing solutions that you can do yourself.
If you flashed the update yourself, you might have used an update for a different region. If this is what you did, you need to find the update for your model number and for your specific region, country or carrier. Or you can flash just the modem img or bin file that has been extracted from a firmware update that is for your region, country or carrier.
If that doesn't work. Try flashing the firmware version that you had before the update was applied.

Flashed U firmware to a U1 but no Carrier apps

I have a sm-g715u1 with latest android 11 firmware and flashed the verizon G715USQU7BUC1. Both are latest ota firmware.
Odin (3.141) showed a succesful flash with all 5 bl,ap, cp,csc and userdata put in. The csc file was non home. However, I dont see any verizon apps installed. There were changes and it does show the U version software installed but no verizon apps. I saw no errors in odin and flashed it twice but no change. I did a factory reset from phone app before flashing a second time.
Not sure what i did wrong . I left the SD card in but dont think that matters.
It has verizon splash screen on startup but thats it. The phone is functional but no different than U1
Is this version (3.14.1) of Odin ok for U1 to U flashing?
Should i have factory reset before flashing? Flash from recovery and not the phone software?
Any ideas will be appreciated.

I see that i can no longer access special menus via the dial pad like I did before the flash. Its like a partial install of the userdata file or something.

So things i noticed after the vzw flash: I didnt get the full verizon bloatware and lost some of the samsung unbranded advantages. I have the vzw 4G icon and Hd voice icon during calls and had the video call option. Video calling didnt work and had to call vzw tec support to get it turned on. A ticket was opened to have it done and its now working fine. Before the flash i was told it couldnt be done so flashing to vzw must have helped here. One thing i have noticed is reception in fringe areas after flash in terrible by comparison. It now enters extended network or no signal at all where before it stayed on lte even with 1 bar and could text and call. This must be a PRL difference or something. The unlocked, unbranded version is way way better for fringe areas. In town i noticed no difference.
At this point i could try to enter recovery and wipe then direct to flash the vzw firmware again to see if i get all the bloatware but to be honest the poor signal and tower handoff with the vzw firmware has convinced me that the U1 firmware is better for me overall even if i lose the video calling after switching back.
At least with the U1 version its a little easier to experiment to see what works best.

No eSim support in my SM-N986B/DS after flashing stock rom

Hi,
I have SM-N986B/DS, untouched KNOX, no root, bootloader locked, OTA updates were installing automatically. CSC version was "COS" (Greece/Cosmote). I had an eSim support and it was working fine, as I was using it without any trouble simultaneously with other physical different sim cards. Suddenly I realized that I can't add credit card to Google Wallet and use it with NFC - message from Google Wallet keeps telling me that I can't add a card because my device doesn't meet the security requirements. I'm located in Poland, so I thought it can be related somehow to CSC. I decided to flash "XEO" stock ROM (Poland/not branded), I downloded it from samfw.com/firmware/SM-N986B/XEO (version N986BXXS5GWA7). I thought it wouldn't harm, as I mention, I was receiving OTA updates. After successfuly flashing rom through Odin v3.14.4, phone info shows CSC: "EUX/EUX,EUX/EUX/COS", I was able to use Google Wallet with my credit card. Next, when I was configuring my phone as usual, I realized that I can't add eSim anymore. Nor through my service provider app (Orange), nor through scanning QR code. Each time it was giving me the error message that eSim feature is not supported on this device. I went to Android Settings > Network & Internet, but I couldn't find eSim settings where they were before flashing! Settings dissapeared from my phone. Next I spent whole bunch of hours trying to figure out what kind of crap is this. I flashed COS rom succesfuly, because I was trying to revert to previous installation. Still no eSim settings. I tried all other Poland located stock roms (branded), but eSim settings still not showing. I tried UK unbranded stock rom, but still no go. Then I tried to flash stock rom from different group of roms (Brasil/ZTO) as I read somwhere that all stock roms I was trying were EU located, so the CSC may not be updating as expected. After flashing "ZTO" finally eSim settings were accessible in my phone settings and I could add an eSim and it was working, however again I can't add my credit card to Google Wallet, as it keeps saying that my phone doesn't meet the security requirements. I flashed again XEO, because if I must choose, I want to use NFC with my credit card and eSim feauture isn't that much importat for me, because phone has two nano sim slots I can use. I can tell for 100% that my phone still has untoched KNOX, no root and locked bootloader and while in download mode it shows "0" at warranty line, so as I understand, the warranty is still fine.
The questions are:
1) Can any one explain me what happened? Why there's no support for eSim in all EU located stock roms for my phone, even in the COS one?! What I did wrong?
2) Is there any chance to flash some subpackage or is there any other method that will allow me to use eSim feauture with XEO stock rom?
I can't stand how it pisses me off. Thank you in advance for any help.
Kind regards

Question Is it possible to in-place flash? As in, flashing the same firmware already on the phone.

Hey, first post so sorry if I say anything off lol.
I have a G996U purchased from Verizon that I flashed to U1 firmware like 2 years ago when I first got it, and have had no issues since. I had a OTA software update the other night that seems to have triggered a carrier lock in my phone. The phone works fine for 5 minutes, then I get a popup telling me the phone is locked and to contact Verizon, despite the phone being from Verizon and running a Verizon sim. I went to them and unfortunately nothing they did could resolve it (new SIM, eSIM, etc), so they shipped me a new phone via insurance. I'm wondering though if I could save myself the hassle of transferring everything and do an in-place flash on the phone to see if that clears up the issue. I am already on the newest firmware (G996U1UEU5EWB1), so I can't upgrade, but I was wondering if I'd be able to flash the same firmware already on the phone while keeping all my data. Thanks.

Yes, just flash with home_csc.

Thank you, just also want to ask bc I'm actually not sure which software to go for. I thought I had flashed XAA long ago, and I'm definitely on U1 firmware, but when I check "Service provider software version" in settings, it says VZW rather than XAA. Is it safe to download XAA firmware for a reflash or should I just do VZW to be safe?

You can flash any csc firmware.
