Just curious, how did you end up with this situation ?
[Samsung Galaxy Watch] congusto:
You don't have to use combination software for the R800 to change the CSC. Simply downgrade by installing any older stock firmware than 4.0.0.7 using NetOdin. Then use the old method to change the CSC and update back to the latest firmware either by automatic OTA or flashing it by using NetOdin.

In my view the old method is much simpler, have done it a few times this way in an effort to get SamsungPay going (which failed because SP is not supported by the Credit Card companies for foreign users, at least not yet). Why do you want to change CSC?
[Samsung Galaxy Watch] mariopetit:

[Samsung Galaxy Watch] Gioooow78:
Thanks for the advice!

Yes, to use Samsung Pay. On the site of Paypal says you can add Paypal to Samsung Pay.. If that doens't work there is no reason for me to downgrade etc.

Is there someone who can confirm Paypal can be linked?
[Samsung Galaxy Watch] congusto:
AFAIK linking PayPal to Samsung Pay is not possible in The Netherlands, where PP is an online pay service only. PP doesn't issue credit cards in the Netherlands, as they do in the US.

Curve in the UK is supporting Samsung Pay, but at the moment only for UK users. They are working on allowing foreign users as well. I am betting on Curve, for now.
[Samsung Galaxy Watch] mdaamir1989:
Has anyone tried downgrading the firmware on their Galaxy watch from Tizen 4.0.0.7 to lower versions for Samsung pay to work ?

If yes, can you please link the firmware you used and the process followed for the same.
[Samsung Galaxy Watch] dinooo1:
Of course, I did as you mentioned above.

Unfortunately the root on command gives the permision denied message. Combination firmware is required as adfree and smeone else noted.

Thanks to you All.
[Samsung Galaxy Watch] maujogue:
Me too. I received today my curve card. Hoping they add samsung pay Europe wide soon.
[Samsung Galaxy Watch] stef7EAmis:

I ask this before, but maybe it has been lost in other questions :)))

Does anybody know something else besides Curve?

A service like Curve, but from anywhere, not just Uk?

[Samsung Galaxy Watch] maujogue:

[Samsung Galaxy Watch] stef7EAmis:
Romania and my CSC of the Watch is set for Uk, but I can change it later :))
[Samsung Galaxy Watch] maujogue:
I guess no option is available for now. Only countries were an app is available is UK with Curve, France and Portugal with Lydia and France with Max. If anyone is living in one of these countries, give a look.
[Samsung Galaxy Watch] ernani:
Hi everyone,

Today I just received my GWA2 alum 44mm black R820 model. I live in Greece and the shop I bought it from imported it from Romania (R820NZKAROM). To be honest I don't care about Samsung Pay, but I'd definitely like to use the ECG features of the watch, whenever they become available. Would you recommend to try chaning the watch's CSC before setting it up NOW and if yes which CSC should I pick (perhaps to a country that could get the ECG features earlier or get more frequent SW upgrades)?

Or shouldn't I worry that much, and hope that Romanians do get their updates more or less on time?

Finally, if I choose to perform this process later this year (perhaps when I'm forced to by a release of a feature or update like the ECG that does not get released for my CSC), when I downgrade to an earlier firmware (the combination one indicated), and back then to stock, does the watch get completely wiped (meaning the data partition as well)? I have to set it up from scratch?

Sorry for my newbie-like questions. I've owned several Samsung phones and ODIN / TWRP has always been my friend. I never kept a stock (non-custom) ROM more than the first day of purchase. Somehow though the process for the Samsung Watches seems more involved (and prone to failure)...

Thank you in advance
[Samsung Galaxy Watch] kbboykin:
Yes, I believe it can. I did it in my Galaxy Watch, but I'm wearing my GWA2 and im not home.
[Samsung Galaxy Watch] MsKC2020:
Hi, thank you for the descriptive instructions, they have been really helpful as I struggle to find my way through this issue (my R820 was bought online as a gift for me - no Samsung Pay or Spotify evident : I'm in Australia) I'm having an issue with the NetOdin steps as it doesn't seem to be recognising the downloaded combination and stock software (when I click on AP - it goes to windows search but the software that is definitely in the download folder does not show up). Does anyone know if there could be a reason for this? I have tried finding the file path in the drop down and it seems to show in the AP box, however I don't know if it is "checking the file" or if it passes? I tried starting it and got this...

[IMG="Netodin log"]C:\Users\kathy\OneDrive\Desktop[/IMG]

My watch is on Tizen 4.0.0.7 - could this be the issue? I have read that some people have followed this method on 7 and it has worked, do I need to downgrade? If so how do I do that? Thanks in advance for any help/advice!!!
[Samsung Galaxy Watch] Saqrez:
Are you able to use this method with a higher firmware version than the combination firmware file that is provided? So I can downgrade to enable samsung pay and update it afterwards to the latest firmware that i'm on right now?
[Samsung Galaxy Watch] congusto:
AFAIK you can use any combination firmware version as long as it is built for your watch model. Combination firmware allows you to change files (and thus the CSC to get Samsung Pay) on your watch that are protected in stock firmware 4.0.0.7 and higher.

Downgrading your firmware to an older version to change your CSC "the old way" (running the CSC manager on your watch, which can be done up to firmware 4.0.0.4) only works if older firmware is available for your watch. This is why downgrading works for e.g. model SM-R800, but not for the R830 who's first firmware was already 4.0.0.7.

[Samsung Galaxy Watch] 9shikaku:
First of all, thank you so much for this guide! I live in Japan but am moving back to my country next year and wanted to change my region to my country's, and this worked perfectly.

Now I have a... weird question. Can we somehow get blacklisted by Samsung for doing this? Right now I can't access samsung.com, or check for Android updates on my Note 8, and can't access the Galaxy Store or any other Samsung Service while connected to my home internet (not even on my PC). I can however, access all of those things if I use my Pocket Wi-Fi or my VPN (changing to a Japanese server as well, did this just to check there was nothing weird going on with their Japanese servers or something). So this got me a little paranoid. But it is weird that they would block by IP and not by device, so I am hoping it's some coincidental freak problem with my internet or something and all will go back to normal soon (it's been like this since last night).
[Samsung Galaxy Watch] bilalbasra:
how you do it.?

how you do it. as i am also on the same version 4.0.0.7 one ui 1.5. but after flashing combination files provided in the first post. i go into test mode. i think because i use a downgrade version. then i flash the latest one again and now watch is like back again.

did you use some different files?

Thank for the link, but, must pay for this file, and i hope if it's a free one.

Also, i find that the 4 0 0 6 is the latest update for the R825F

If someone can share a free combination many thanks :)
[Samsung Galaxy Watch] dinooo1:
Adfree noted all combination files on easy firmware might not fit r825f.

BTW. Since few days 4 0 0 7 has been uploaded to my watch, so now R825FXXU1ATA1.

Still waiting for any combination file does fit it. Need to change CRC.
[Samsung Galaxy Watch] b3n1:
Hey! This is working for SM-R820 aswell?
[Samsung Galaxy Watch] adfree:
This is not 100 % correct, because I have none of these files with R825 inside filename...

Correct is... 1 or 2 Combination Firmware are for SM-R825US

But here are few more files...

And I have NO access to these files...

I still need help of SM-R825F users...

In sboot.bin Bootloader I can see text string:

SM-R825F[B]S[/B]

The US variant have:

SM-R825U[B]S[/B]

Now still my Question is... SM-R825F shows in Odin screen:

SM-R825F

or

[B]SM-R825F[B]S[/B][/B]

Normally this takes seconds to check...

But again I get from nobody answer... :rolleyes:

If this is confirmed... we could safer check Combination Firmwares... because there are few more with R825 in Filename... WITHOUT Flashing.

Simple text search in Bootloader sboot.bin file...

Hi, long time since I wrote on XDA. I just wanted to to thank all the contributors in the thread.

I live in Sweden and bought the 44mm Bluetooth only version online (R820). Samsung Pay was missing, and I had already upgraded to latest firmware version r820xxu1bta1, the combination firmware from [MENTION=1030585]adfree[/MENTION] and the numerous instructions and clarifications in the thread made it easy to update the watch. All working with Samsung Pay and the latest update was applied automatically again once a search is performed from wear app on the phone.

Switched csc from SEE (south east European unbranded) to NEE (Nordic countries unbranded)

Changing Region CSC on R820

I managed to modify my R820 with this method, but I ran into some issues.

Firmware that I used (Thanks to adfree): https://xdaforums.com/showpost.php?p=80340381&postcount=8

My watch (purchased in China) was on Tizen 4.0.0.7 when I bought it, main reason for me to switch was to be able to use spotify. I later found out that all my efforts were wasted since getting spotify to work could have also been solved in a different way (without modifying csc). LOL :silly:

Anyways, the guide is working fine, didn't follow the steps entirely the same, but I successfully changed my CSC. Problem came after I flashed AP with netodin for the first time. During bootloading I get this info:

LOT_ID = NHCKH

ASV TBL VER = 2

HW REV = 5..... (see complete info in attachment)

I figured this would go away after flashing the original firmware, but it did not. Then tried updating the watch to the latest software. It seems the update successfully finished, but after restart an error message came that "the update could not be completed, try again later". Everything else on the watch was working fine. Even though I almost never restart my watch, it's always on my mind that it's not STOCK anymore so I tried manually downloading the newest firmware. Had to pay 3 dollar's, flashed the files through netodin successfully, and I'm now back on the latest firmware version. BUT still the LOT_ID info won't disappear.

Anyone have an idea how to get rid of it?
