[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

Alternating Firmware on my SM-P907A

Alright, Question first:
Is it possible (obviously not recommended) to put firmware for a similar version, like SM-P905 on my SM-P907A?
Details:
To keep a long story short, my device is soft-bricked. I can boot into Recovery Mode and Download Mode. Fastboot is over my head with the tutorials I've found. The file system is corrupt and it can't/won't mount. I don't really see too much information available for my case with my device and I don't understand what can be interchanged and what can't. I've tried to re-partition, flash multiple times using Odin (always ends in "Pass!"), and factory reset the device all to no avail. I read some articles on flashing to the original firmware, and I would flash to the original firmware, but the only source I was able to find it from says that it'll take about 2774 weeks to download (P907AUCU1AND7 for those of you who're curious). It's an AT&T carried device by default, but I don't want, nor need a SIM card in my device, so that'd rule out any need for 3G, LTE, etc. However, Wi-Fi is needed. I don't really have any experience using custom roms (cyanogenmod, CWM, Pac-Rom, etc (not that my device isn't support by them anyways)). Besides the 3G/LTE aspects, I saw that the 907 and 905 use the same hardware which is why I ask: Could I flash to custom or stock rom for the 905 model to my 907 model and not hard brick my device?

With a fast and stable Internet connection the files here worked. Took a few tries to get some of them to successfully complete the download. About one hour. http://forum.xda-developers.com / galaxy-note-pro -12 / general / sm-p907a-att-version-news-t2850564

S6 Purchase

So I bought a 2nd hand S6. The price was good, not great, but good and the phone functions very well with no issues. I probably didn't look at it as closely as I should have, but live and learn. Anyhow, the phone is still on 5.1.1, so I went to flash it in Odin to 6.0.1 - nothing worked. The model says it's an SM-g920f, however, when I go into download mode it's listed as an SM-g920p. Also, the bootloader etc are all 920p. I didn't think twice about it being the f model as I am an American, but I live in the philippines. It is very common to see the international versions of phones here. I know that the p model is common in the US as a sprint phone, and I should have keyed on the fact that when I opened the browser, it took me to the sprint webpage right away. The device is of course rooted. I cannot upgrade it using smart switch. Of course when I initially tried to flash it in odin with a 920f rom, it failed miserably. So, I am wondering if I flash it back to a stock 920p, will it cause me issues?

Updating problematic device from Android 6 to 8

Hello,
I bought an S7 from eBay, it was marked as a "new" and "UK" phone. I factory reset the device on receipt and apparently worked fine to start with. However, there have been a few problems (poor signal, battery life, echoes in video calls) and I noticed the device was still on Android 6, so wondered if an update to Android 8 might help (?).
There is no menu option available to update Android so I started looking into flashing firmware. On further digging, the device seemed an official SM-G930F but "United Arab Emirates" appears in the "About Phone" section.
I downloaded some stock firmware (Android 8, UK Vodafone which is the network I expect to run it on) and tried flashing with Odin 3.13 and it failed with error "unsupport dev_type" on the phone screen. Any suggestions?
I also noticed that in "Download mode" the phone said it was a "SM-G930V". I wondered if this was why the flash had failed. For the SM-G930V I only seem to be able to get USA/Verizon stock firmware. Might this work or would I have trouble using this in the UK?
Any help would be much appreciated. I'm a newbie in this area so apologies if any of these questions are answered elsewhere.
Many thanks,
Edwin

Go to the play store and install Sam phone info, then look at what chipset it lists, you don't want it to be Qualcomm Snapdragon, Eyxnos is what you want to see.
G930V is US Verizon firmware
Report back please.

Thanks for your reply! The "hardware/board" is "qcom/msm8996". Where does that leave me?
I noticed that the Bootloader & Baseband Versions begin G930VVRU but the PDA and CSC versions begin G930FXXU. Not sure if that means anything.
Thank you!

Well the person who sold it to you is a liar for starters, it's not a "brand new UK device", it's a US S7 (G930V) Originally bought for the Verizon Network in the states. They are difficult to do anything with as the Qualcomm boot loader is locked down.
So your first option is to update the firmware to the latest Verizon Oreo, probably not worth it since that firmware is designed to work on a couple of frequencies only.
Next option is to flash unbranded US firmware with a modified version of Odin that ignores mismatch devices etc and just installs the firmware. You will need to use this version of Odin from this thread >>> here Odin 13 PatchD.zip is the one you want.
Unzip, run Odin, place phone into download mode flash firmware. You will need to download G930U from Sammobile or undato.com The 3 letter code should either be USC or XAA.
Any questions please ask.
Also before flashing please remove you google account off the phone.

Thank you for these detailed instructions -- much appreciated!
Presumably using this version of Odin carries a high risk of bricking the phone if I get anything wrong?
Out of interest, what's the reason for removing the Google account?

Because it's a further complication with FRP lock you just don't need after flashing. Just add the google account after flashing and your good to go.
With regards to flashing yes there's always a risk that something can go wrong, that's why you take your time and follow the steps exactly. In your case it's pretty straight forward and remember nothing changes on the external SD card, so anything you want to keep can be moved there before flash.
I would also mention that theoretically you could flash UK unbranded (BTU) but it's for G930F Exynos devices so best at this stage just get the device on unbranded Qualcomm and working on UK networks.
let me know how it goes.

Hello,
I've just tried doing what you suggested (I think!) and I got a failure. Odin said "FAIL! (Auth)" and the phone said "Secure check fail: apnhlos". I tried rebooting and got a security error. So I tried Odin again and it passed.
However, now the phone won't boot, it alternates between "Samsung Galaxy S7" and a blank screen. In recovery I get:
"#fail to open recovery_cause(No such file or directory)#"
#Reboot Recovery Cause is [UNKNOWN]#
No Support SINGLE-SKU
File-Based OTA
Supported API: 3
dm-verity verification failed..."
Any ideas?
Thanks a lot,

Ok, so try an earlier G930V firmware and please make sure you are placing the file in the right places with Odin. The US carriers have all updated their firmware and often closes the loophole which allows the patched Odin to work. Then it's just a question of waiting until someone develops a workaround again.
Also you can pick up an S7 from ebay for about £100 now, your always going to have problems with a qualcomm device on UK networks. Where about are you in the UK?

Thanks! Actually shortly after posting I found a suggesting of using CSC not HOME_CSC, which enabled the flash to work (at the expense of phone data, as expected).
The device still does have a few issues though, as you predicted. Is the radio hardware different for Qualcomm? Might need to buy another then. Any advice to avoid being scammed on eBay again?!
Thanks so much!

Well you could flash G930U which opens up all of the radios for the US and you may have less issues but US and European devices have different chips so your never going to be able to flash any EU generic firmware. I'm addition the US and Europe are different cellular regions with different operating frequencies. You can get by with what you have but never get full functionality.
I think you were just unlucky with this phone on ebay, there are plenty which are genuine EU region devices.

g970n vs g970f

Hi all,
Yesterday I bought an S10e under the impression that it is sm-g970F.
Trying to flash Android 11 I discovered that it is actually sm-g970N.
Is there really a difference between them?
Should I be worried that some functions will be missing/unavailable?
Also, in the settings, it appears as g970F. How did the seller change it??

I have the same problem i tried to update the phone to the latest sm-g970f rom (figured if it's already installed it's possible)
And non of the roms flashed only when i decided to try latest sm-g970n rom it flashed however i bricked the phone and i have no idea what to do now.

So after digging into the issue since i have the same problem here are my conclusions:
1. The phone is a Korean Variant G970N it is probably a renewed phone and not a new one.
apparently it's okay for an importer to take used phones (from Korea in this case) and replace all the cosmetics but of cause leaving the used MB.
Now here is what you should worry about, in order to flash the G970F Fixed Rom (there is no way you have updates) they used a Custom Kernel which means the phone was rooted and now Knox is tripped (this not reversible).
(Download Phone Info from play store and check knox if it shows 0x1 then your phone warrenty is void and some features won't be available any more for example - Samsung Pay).
So what should you do?
Well if you still have the option i would have demanded my money back!!
One thing that i am perplexed about is how in hell is this legal?!!!
If you no longer have this option or you want to keep the phone you have two option:
1. Flashing Korean Unbranded Firmware (KOO) which is pretty good it doesn't have bloatware or issues as far as i can tell, i only found one down side for it, the phone language selection is small but if you only need English (like any normal Human) then you are golden.
2. Keep the G970F ROM but bare in mind it will receive no updates and no security patches.
I am still looking for a proper way to flash G970F Firmware over G970N for now i haven't found any internet source that will confirm it's even possible.
So how did those importers\sellers did it, they probably flashed it with a Cellphone Lab Software (not Odin solution) and used a custom Kernel to fool Knox, like i said before this is practically a crime and i don't understand how can they sell used phones as new and get away with it!!!!

I had the same suspicions....
I'll try going to the lab that sold the previous owner the device and deal with them tho it looks like I just got scammed...

Sorry to bring this up again but I've just had an idea following JerryRigEverything's video:
What if I transplant SM-G970F components from a broken device that no longer works or in use in my SM-G970N which is supposedly new.
My N device is now bricked for some reason I couldn't solve, though my suspicion is that it has to do with incompatibility with the SIM card I use.
When my device did work, it worked great! ...besides battery issues that are most likely a result of the incompatibility aforementioned.
Will this work? If so, what components do I need? I already know I'll need the logic board but as seen in the video, there are several more antennas, should I just copy what Jerry did?

Hi Vegetto,
I am from India and buy a galaxy S10e from UAE, It is showing G970F in the Phone's about but the problem is It is a G960N. Now, When I see in Sam Phone Info app there is Bootloader version - G970N, PDA Version - G970F, CSC G970F.
It is also a Knox tripped phone. Knox 0/1.
But if I see in Samsung code by typing in keypad *#12580*369#
it showing like all option in Odin:
BL: G970F
AP: G970F
CP: G970F
CSC: G970F
Does this means I can flash new Firmware on the list of SAM Mobile website, with G970F series firmware, It also showing in SAM Phone Info App that there latest firmware G970FXXSEFUL1/G970FOXMEFUJ2/G970FXXSEFUJ2.
I am in India right now.
Please help me, My email Id is -- [email protected]

It actually means you cannot flash SM-G970F the only roms you can flash are G970N.
Also if you want the phone to get security updates you must flash the original phones bootloader version, my suggestion download the G970N KOO firmware it's a global firmware. As for the knox it is tripped and there is nothing you can do about it.

How can I flash the original phone's bootloader version?
Where from I can download the original phone's G970N KOO Firmware and is it official Samsung Firmware?
How are they able to flash G970F? Is it custom Rom or do they use the original one?
I searched that my phone is using G970FXXS4BTB3 firmware which Vietnam XXV and same number found at https://www.sammobile.com/samsung/galaxy-s10e/firmware/SM-G970F/XXV/download/G970FXXS4BTB3/322678/ in an old update in 2020.
So see the attached screenshot, can I flash its latest version with odin. Of course, there is a chinese written in recovery mode installed when I go to its recovery mode for flashing with Odin.

I have a similar problem right now on my Korean S10E. Device is SM-G970N. I need it to be in Turkish. Only Themes item in Settings is in Turkish- very interesting- The rest is in English. App names are mostly Turkish Settings app name is in English.
The bootloader is unlocked but the phone is not rooted, Knox seems not tampered.
Could not start OTA update at first, I have upgraded a few versions from PC via Smartswitch. Just then noticed OTA also started downloading. The rest of the updates went on from the phone until upgrading to 12, there was a message like "All of the updates were not succesful." OTA update no longer responded. This time I turned back to Smart Switch. Update finished this time and finally I am at the latest version.
I only need Turkish in Settings. I used some ADB commands and an app called MoreLocale2. It did not work either. This has to be simple. Turkish exists. Keyboard is Turkish but not Settings. Quick links and most other things are strangely mixed English and Turkish.
How can I enable full Turkish?
