I finally managed! Samsung Pay works. A huge, huge thank you to @adfree. Thank you also @Jivkorusev.
And if someone launched Samsung Pay and activates the Curve card, they can use my code N2939WAE Then you and I will get £ 5 each.

Have you changed CSC? There are no problems with LTE for this reason?
I want Samsung Pay But I'm afraid of losing LTE connectivity.

Esim is working without problems. Samsung Pay too. I've sent you private message.

HI!

I have a Galaxy Watch 3 LTE, with model number SM-R845FOXX1BTH4

fota-cloud-dn.ospserver.net/firmware/INS/SM-R845F/version.xml

I am using a OnePlus 7 Pro, and have setup the esim, by borrowing a friends Galaxy Phone.

I want to install ECG, BP and Samsung Pay, (dunno if its possible to use with a non-samsung phone).

After reading the forum I think only ZTO has all three option

It would be great if someone could guide me and help me with the right files and process to change the CSC from INS to ZTO.

If Samsung Pay is working in India... for you... with your actual Settings...

Then why not simple sideload BP + ECG and isnatll modded APK on your OnePlus 7 Pro...

I am from Germany and I have only Samsung Phones...

So no idea about your Hard + Software combination...

Anyway.
It is much easier to start with BP ECG crap first... with NO Firmware changes... ;)

Best Regards

I have tried sideloading the app, but I get the error.

I even tried to uninstall the pre-loaded BP app, it uninstalled, but still not able to sideload BP+ECG.

The best and easy way, change your region to XAC, sync the watch tour phone to gain the phone dialer on your watch, make sure to update your watch to the latest update on XAC, when update is done.

Open the dialer on watch and dial : *#243203855#

This should give you access to all CSC then chose the country code you want, In your case KOO , the watch will reset and reboot, after linking the watch you should see a software update available for your region.

Hope this help.

"Connection problem or MMI code not valid." It si my translation form Italian so the words may not be precise, but that is the sense.

    How To

    Hi guys,
    I want to clarify something I have learned the hard way.
    Change the region in easy, but you should know what is used for.
    Net odin: Is a program that allow you to upload the firmware to your watch.
    Combination firmware: Is a firmware that MUST be installed before doing anything else. It will allow to use sdb tools. You install with Net Odin. It must be the right one for your watch model.
    SDB Tools: This is cmd software that can read two files from your watch and save, "pull "them in your computer. You will need to use the right version (windows, mac ubunto and so on) Once pulled the files, you will mod, with a text editor, the region code and save the files. Then you will upload them to your watch pushing them always with SDB tools "push".
    Firmware: Is the actual working firmware that you will upload to your watch after the operation above. Usually is a packed file containing three files that you will upload using Net Odin
    I hope this helps the ones like me not very familiar with the procedures required.
    Ciao ciao

    I bought the GW3 watch yesterday. Unfortunately I live in Gibraltar which for some unknown reason is considered the backwater of the internet and we are blocked by both Google and Samsung - Google does not let us buy anything from Google Play, although we have found a way around that. Samsung goes a step further and we cannot even browse their store :(

    My question is: I've seen videos on how to change the Active 2 region and I'm wondering if there is a procedure for GW3?

    Until I change the region I will not be able to get any apps installed other than the ones preinstalled in the watch. BTW I also tried the SDB connect and I cannot connect to the watch even changing the port number...

    has anyone figure out the way to change the region from Canada to US?

    How did you do it? after changing the csc from EUR to PHE I can't send the commands to the clock. it tells me :error writing,system read only.
    Hello are you in developer mode on your watch, and after installing the combination CSC does your watch have to restart, and that's when you have access for reading and writing. I follow the tutorial on Youtube and I advise you sometimes to pause and move forward in slow motion because the guy is going very fast and you have to be able to follow him.
