Depends on the actual model number you have, so you need to tell us that. Snapdragon phones vs Exynos phones have different procedures.
Once you identify which you have, there are threads here on how to flash stock roms. Read them carefully and ask questions there.

Samsung Pay SM-9208, Rooting & Flashing ROM

Purchased Note 5 gold on eBay from US seller. Turns out the phone was from Taiwan. This before I knew about model numbers and I thought that the bands were all I needed to think about to make sure it would work in southern VT US with AT&T. Obviously, came to find out Samsung has regional model numbers.
I love the 9208 for many reasons: unlocked, no AT&T bloatware, and a few other things that just seem to make it a better phone. However, no Samsung Pay and I can't register the phone on Samsung in the US. I don't care about the registering, but I REALLY want Samsung Pay. So, my question....
1. Can I root the phone and get Samsung Pay? I read somewhere that rooting "kicks off Knox" which is apparently bad (I have no idea what that means). Does that mean that I can root and still can't get SP? Also, if I root, what do I lose and what do I gain?
2. Flashing roms. I used to do this in the old days, but spent a few mindless years with iphone (for my husband and daughter) so I am starting over and consider myself a noob. So, can I flash a rom to get SP? Do I flash, then root? Does flashing automatically mean I am rooted? Or do I root first, then flash, then do I get SP? Finally, what do I lose flashing and what do I gain?
3. Lastly, does anyone know if and when the Taiwan model 9208 will get SP from Samsung?
Sorry for all the questions - thought I would get it all in one post! Thanks so much for any help and advice. Oh, and before anyone lectures me for buying non-US model just to get a color or something, please refrain! I already know I should have realized Samsung had regional models - my stupid mistake!
Welcome to the club!
I got the Singapore 920i version 1 for the Gold and 2 for the 64gb !
In answer of your questions. ..
1. No. Root is incompatible with SP.
But I think Android pay can work with Dr. KETAN'S rom and his kernel
Haven't tried it out yet but at least it let me install. SP wouldn't even allow install.
2. Flashing as of now will help no effect on SP. But there are some Roms out there that improve battery life and have mods..I'm on the latest Dr. Ketan 4.1
3. Unknown.
As to if the version you bought will be compatible with your carrier you can check on http://www.willmyphonework.net/
Compare your model with the 920a for at&t
Oh and enjoy ?

If a buy a G9730 (Chinese S10) will i be able to use the OFW from other countries?

Or CFW from this website made for US decides (G973U).
What i mean is, what determines what FWs can be installed on a Galaxy phone? The whole Model Number or just the first 5 characters (G9730, G973F, G973U)?
Will i be able to install any other FW for Snapdragon?
Thanks.
usually you cannot flash fw from another region, tho if the hardware is completely the same, i don't see why not.

well global firmware(if there is such a thing) would be more towards the n960f since it is more popular and also the same same chipset as ure phone. its sold in UK, greater asia, india, Oceania etc...)
the n9600 is a snapdragon chip. and only sold in china and south America.
but regardless you cant flash stock firmware on different model devices. its a known fact.
if you root then u can flash custom n960f roms no problem on the n960n.(i have it too and been flashing all sorts of custom roms made for the F variant)

thank you for the answer I want to flash stock ROM but not the Korean version, because I don't want to lose the features on One UI ... if you use a custom ROM what do you mean? is there a tutorial for a problem like this?

u cannot flash any other stock firmware than n960n with odin.
if you want to flash a custom rom.zip , you need to install twrp recovery and root. this will void warranty and also trip knox and some services will no longer work:
samsung pay
might be others.
please read the guides and discussion forums for more information on rooting.

what do you think, because I am a beginner I better use the current stock ROM (N960N) or have to replace another ROM? actually I just don't like Korean accents and Korean network operator logos when I turn it on or trun off my device because I'm already outside Korea. then what is the ROM recommendation for me?

As a beginner the best and most important thing you need to do is research and read up on these topics.
Head over to the development forum and see what each rom offers and choose the one which sounds most suitable for you.
None of us can answer whats best for you dude only you know that.
The nice thing is you can flash and try out as many roms as you want!

I too want to flash the Spanish stock ROM, so as to get rid of d the bloatware and also to use Samsung Pay. A friend of mine told me to buy the Korean version and then flash the Spanish stock ROM, which he did with his note 8 and didn't trigger Knox. I'm getting the Secure Check Fail: Bootloader error when trying to flash with Odin, it's stuck at SYSTEM flashing. Don't know what to do anymore, tried rebooting everything, changing USB ports, running Odin as an admin, and flashing different versions of Android.
Can anyone help?

you say that u bought a sm-n960n (was told to)
then u say that you were aslo told to flash a spanish firmware from a sm-n960f device.
that is very very misleading.
again, you cannot flash firmware from a different model.
your buddy gives the best advice. he is your friend. listen to him always.

Strongly agree to you ....

I know for a fact that the Korean variant of the Note 9 and the international variant both run on the exact same hardware. With the only differences being in the bloatware included with the Korean variant. So theoretically speaking installing the Spanish N960F/D variant's OS onto the N960N should work perfectly without any issues

it work only if you flash a custom ROM, even thought they are the same but you cannot flash a F/D firmware with odin in N model, it mos be a bootloader thing or something else.
by the way the n9600 is a snapdragon model so that is even more impossible.

Flashing different region stock from 960N (Korea) to 960F (Asia)

The specs for both models are same including CPU but 960F (Asia) support DUAL sim whereas Korea only SINGLE sim.
If I odin 960F to my Korea model phone, will it still work? or probably freeze on E.g. Settings when I click Sim 2?
How about the Samsung Pay?
If firmware 960F can work, can I use Samsung Pay in Asia? or they are some in-built mechanism E.g. Knox that will prevent this?
Same question. I have a SCV38 - Japanese KDI/AU Galaxy S9. I have only Android 9, but there are a bunch of US Snapdragon Galaxy S9 based on Android 10. Can I flash this (US firm on JP phone)? I just want to get to Android 10. I have a feeling that wont work, and I checked for the S8 - US and JP phones, altough based on QC chipset had other hardware differences...
Anyway, appreciate any advice on the matter.
Do you have solution? I have same problem

As long as the specs are the same you can flash any region rom. You will just have to try it yourself and see if both sims work. Google pay shouldn't have any problems. The only problem you might have is some roms have different baseband files so you might not get network connection if it's not right for your region.

Make sure in download mode you don't have RMM prenormal if you flash Android 10 and it's prenormal you will never be able to get rid of it.

Question about flashing firmware from a different region

Hey guys,
I've been up and down the forums looking for answers and come out thoroughly confused, so thought it would be best to ask for help from the professionals.
I am in New Zealand and have recently purchased an imported S10 from the states (site never said it was imported, would have gone local had I known), model SM-G973U. I've since realised that the phone will not update, and has been stuck on the June security patch since I got it. Contacted Samsung NZ and they said that because the phone isn't approved by my local carrier (Spark) no updates are getting pushed through.
I've thought of flashing a Spark-based version of the phone so I can receive updates but because the local versions of this phone are a different model (SM-G973F) I'm worried whether this will even work or if it will brick my phone entirely.
Is this something I can safely do, or will I have to resort to flashing updates manually?
Thanks guys, these forums really are great.

Hi dude,
Don't try to update your G973U with a G973F firmware coz SoC of those devices are different ! Your model has a snapdragon but G973F (international S10 version) has an Exynos (Samsung made chipset).
What you can do if you really want to update it is to download this firmware and flash it through latest Odin (google or youtube this if you don't know how to proceed).
P.S. Firmware I linked here is the USA unbranded one, idk really know if this CSC will support your local carrier so make a backup of your device before processing !
Hey sorry I've been too caught up in life to try this until now, but I gave that firmware a go, flashed it with the latest odin and it's worked without a hitch, carrier settings intact and all.
Thanks for the guidance!
