Hi all,
I bought my Galaxy Note 9 mainly for Samsung Pay and just realized that there is a regional lock for Samsung Pay. (I don't care about other things like VoLTE or Wifi Calling).
My Note 9 is SM-N9600 and the CSC is TGY (Hong Kong).
I wonder whether there are any ways to change the CSC from Hong Kong to USA so that I can use Samsung Pay in US?
I have read lots of posts in this forum, but got no luck. There are some related threads:
for S8/S8+: https://forum.xda-developers.com/galaxy-s8/how-to/guide-changing-csc-s8-s8-root-t3799045
for N960FD: https://forum.xda-developers.com/galaxy-note-9/how-to/note-9-n960fd-dual-sim-csc-change-oxm-t3841000
same question but no answer: https://forum.xda-developers.com/galaxy-s9/help/changing-csc-to-u1-usas-samsung-pay-t3801639
My understanding is that:
- To change the CSC (especially from SM-N9600 to SM-N960U), we must reflash the firmware.
- SM-N9600 does not have any firmware having USA CSCs.
- We can get the USA CSCs from N960U and put it into the firmware of N9600, and then flash it.
- However, the modified firmware will trigger Knox and hence make Samsung Pay unusable.
Are there any suggestions or tutorials on this?
For example, will applying the firmware of SM-N960U on SM-N9600 work?
Thanks!

You cant cross flash firmware from different device versions...ie N9600 vs N960... not happening.
Those of use who have the exynos version can flash US CSC files via twrp. I would think the same would be possible for the N9600.
I search the note 9 forums for the exynos method and go from there even though im not sure if just changing csc will allow sammy pay to work

Thanks for your reply. Actually, I don't think cross-flashing will work either.
My SM-N9600 uses Qualcomm's Snapdragon, not Exynos.
Another thought is that I checked the firmware for SM-N9600, and found there is a version for Puerto Rico and Puerto Rico is listed in the US's Samsung Pay Reward program.
I wonder whether I will be able to safely flash it, and use the Samsung Pay.

If you have an N9600 then yes you can flash any N9600 firmware. Whether or not pay works I cant say sorry
Probably you can try flash HK firmware but with US CSC?
But not 100% sure...
Did you try add adding the card? You would miss out on Samsung Rewards but it should work, myself and some other I have read about just added the card to Samsung Pay and it did work, it does for me. I just can't use and claim the rewards points.

Thanks! I think it may work.
However, what I want is the Samsung Rewards...
I heard a rumor that flashing the Mexico firmware and putting in a Mexican Sim card (off ebay) in before booting up would get Samsung Pay to work.
I want to test it, but I don't have a phone to test with
I have n9600 and have Samsung pay working is US. Just used appbackup and archived Samsung pay framework and Samsung pay from my TMo Note 8 and installed it on the Note9. Have TMo SIM and works fine. Now only if I can figure out a way to get wifi calling working.....

Then my guess is you're out of luck unless you purchase a new US version phone or wherever you're from.

I believe the only way to do so is rooting your phone and using the following guide:

No way to do it as of today without root unfortunately.
I'm sorry but I was saying I've done it, not that it should be possible. Not only with my note 9 (N9600) but with my previous Note 8 (N9500) as well. So your statement seems to be not really correct.

Hi hechon,
Thanks for sharing! Could you please provide more details?
- Can I use Samsung Rewards and get the promotions from USA?
- What is appbackup and how can I use it to archive and restore the backuped apps?
Thanks.

I was able to install the US Saumsung Pay and log in. However, the home tab says that "You're offline".
Let me explain what I did:
- I downloaded App Backup Lite on my previous US S8 and then backed up Samsung Framework and Samsung Pay.
- I reset my Note 9 without installing Samsung Pay.
- I installed the backup Samsung Framework and Samsung Pay.
- When I installed Samsung Framework, the system said that "I upgraded the installed Samsung Framework".
- When I installed Samsung Pay, the system said that "I installed it".
- I opened Samsung Pay and logged in. The home page shows "You're offline", but the other pages look ok.
- I went into the setting in Samsung Pay and reset the app. However, it did not fix the problem.

I think this requires rooting the phone, which trips Knox and disables Samsung Pay.
I have heard about that you can use the SM-N9600 firmware but replace the CSC file from SM-N960U. Someone claims that he successfully did this on his note 7. However, I noticed that after S8, Samsung updates their bootloader and this way may brick the phone. Any idea?
Hey 5G Pioneers,
I am wondering can I flash the sm-g 977b firmware onto the sm-g 977n device through the Odin? Did someone make it?
Since these two models are all using the same Exynos 9820 chips
And from my previous experience of using my galaxy s8, Samsung actually enabled me to flash the firmware in different regions only if the devices were using the same chip version.
I am currently in Australia. The Korean version of 977N is much cheaper, and it seems that is the only network unlock version that I could buy from the market.
Not sure where are you in Australia but I bought mine from a Telstra Sales Rep (based in CBD, Melbourne) where he got a discount code and gave its to me for AUD 1400 for the 512 GB Majestic Black Version, unlocked , I'm using Optus, VoLTE, VoWIFI works fine on it.

Hi everybody,
On Sammobile website, I found 4 firmware Korean variants. I tried getting more information on the "KOO" variant to see if its a stock Samsung firmware without Carrier Apps/Bloatware without luck. I couldn't get any detailed information whether it can be flashed over any other Korean variant. Can anyone here clarify if its possible and If yes provide further details?
Attached a snapshot.
Many thanks

That is the non bloatware Korean version but it doesn't allow me to flash it. I suspect you have to flash it with the userdata file also.
Thanks for the information,
I have a new phone so No issues with user data. How do I flash the firmware.

Hi,
I have successfully flashed the "KOO" variant once with and a second time without "userdata", however that did NOT remove any of the Bloatware/Carrier Apps.
Any thoughts?

I disable the 3 apps then hide them from the app drawer.

Hi,
I did disable the apps which is great, but there menu operator items as well!
Edit : Forgot to mention that the boot logo is of the operator as well.
I was researching something about using the PIT file along with the firmware but can't find the specific PIT file for S10 5g.
Use Odin or the modified version to flash combination firmware. Then flash your desired firmware.
This is the only way I am aware to remove all carrier bloatware and boot logos.
Dual SIM

I am particularly interested in this as the 977N variant seems to be dual sim. I notice it also has additional bands to the 977B varient and I would like to put the telstra firmware to ensure operation of VoLTE VoWiFi RCS etc.
The main purpose is to use at home and overseas. So more bands and access to features (VoLTE, VoWiFI, RCS etc. on my telstra SIM and local overseas SIM) when overseas are the goal.
Unless someone can confirm that the 977N with vanilla firmware will support all the telstra features?
Thank you for your assistance
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.

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.

I have a Samsung Note9 phone with model number: SM-N9600. I heard that there is possible to update my android to 10 version. But i didn't received any update yet. My phone has this version of android 9:
"N9600ZHS4CTA2/N9600OWT4CSK1/N9600ZCS4CSKA
Security patch level: January 1, 2020"
It would be a problem if i try to flash another firmway version for SM-9600 which has the android 10 update?

You SHOULD receive Tmobile updates once you're on Tmobile firmware and network but I don't think it's something that can be guaranteed. Your Primary CSC can't be changed to TMO and therin lies the problem. In the last couple of years Samsung has complicated firmware and CSC transitions on it's numerous array of devices. Lots of potential users lean to an unlocked device thinking they'll have more freedom of choice but it won't always end up as a benefit. I always recommend buying your service provider's device for full functionality but it doesn't always work out since some users tend to swap service provider's on a regular basis.
I'm on T-mobile's network, month to month, no long term commitment which adds flexibility but even being on their network I didn't aquire their Branded Device. I have the Hong Kong SM-G9980 variant. I couldn't care less about 5G, to me it's the biggest marketing scam since light beer. The only other feature I lose is Carrier Aggregation which much like 5G enables faster download speeds. I can easily have my laptop handle this and transfer files or data to my device. So there's no carrier bloatware, the bootloader is unlocked, I get updates from Samsung typically sooner than US devices and still have Wi-Fi Calling and VoLTE via Tmobile. Most users don't do much research to define which device is best suited for their needs. "I got this great deal on an S21 Ultra but..." We can point the finger at Samsung as well, way too many variants leads to a lot of problems.

I downloaded the firmware from SamMobile and Odin then flashed it. I had the unlocked version I purchased from Samsung directly. when selecting the csc portion but it still shows the xaa portion as well. Not sure if I did it wrong but seems to be working for me. Putting it in download mode requires holding volume up/down and power. Every site I visited told the wrong directions

Oh okay okay, did you have to use Sam key after to switch csc? No right cause T-Mobile already worked.

No I just did the firmware. Didn't do anything else with csc. Heard that's a pain in the ass with android 11
