try @adfree guide to exit download mode in this thread
https://xdaforums.com/gear-s3/help/wireless-mode-enter-gear-s3-sm-r760-t3710855/page3
otherwise there is no much you can do now since gear s3 wont charge in download mode. This is what samsung service center does to re-flash firmware (your gear will be covered under full warranty since knox has not been triggered)

Thank you to all authors to finally fix this region lock!
May I ask one thing - watch is already updated to tizen 3.0.0.1 (R770XXU2CQL1), do I need to downgrade it first to tizen 2 and the follow the instruction in the topic header? Or I just start with instruction?
To downgrage I just need to flash older rom?
Thank you in advance.

NOTE: I reccomend unchecking auto-reboot in the NetOdin3 program so it doesnt restart after flashing.

I have no idea if this is the reason to fail 100 %...

My personal opinion... IMHO.

NOT play with any Odin settings... nor netOdin

Use standard settings!!!

Don't touch any settings!

Only select file(s) for flashing...

Best Regards

Okay. just want to confirm that method worked fine for me.

I flashed combination SW first, then flashed CSC/changed region and finally installed standard rom.
I did not uncheck auto-reboot as per Adfree's advice above.
Only thing I had to switch my gear to AP mode for every step.
Also I had to disable my firewall and anivirus to make NetOdin connected to my gear.
In the end I have re-installed Gear app on my phone and updated my gear to tizen 3 by standard Samsung update.

Thank you very much again to all authors helping to find solution for region change!

main reason for me for sure.

I unchecked auto reboot so I could flash the 2 files I'm one shot and not have it reboot between. Your welcome yo do what you like but that's what I did and it worked perfectly.

Can someone help me?

Alguém pode me ajudar? Segui as etapas para mudar o CSC, mas quando terminei o passo 5 (reset de fábrica), você não mais entrou no modo de configuração e não pode mais manter a rede sem fio. Existem ações que posso tentar ou apenas no suporte técnico da Samsung?

Use google translate and then post. don't make us translate for you

Thanks to everyone that worked on and fleshed out this solution!

Saved me from having to return to a 3rd party Amazon seller that claimed they were selling US models and sent me a Canadian model...

Hello All,

i'm reading all this threads with lot of interest and congrats to everybody for the effort you put on this.

I would need help to understand if is possible to change my region from actual DBT (german) to ITV (Italy) to enable Spay on my R770 classic

I currently have firmware R770XXU2CQL1 tizen 3.0.0.1
Can someone help me undestand the entire procedure and the files i need to use for my region?
Do i have to downgrade first before to change region code? If yes, which firmware do i have to use for it?
Is also possible to have an updated link for netodin? The link i found around are all dead.

Thanks in advance

Thanks again for your help @adfree

But i still have some doubt on this step

6. Set CSC code
- In the Gear, go to the Tizen Keystring app
NOTE: screenshots of what your interface will look like: https://xdaforums.com/sho...5&postcount=13
- Type in the following code exactly: *#272*719434266344#
- You will be taken to a list of CSC codes that you can scroll through. Find the code you want to change to and select it. I used "XAR" for US so that i could use samsung pay.

How do i access Tizen Keystring app? Do i have to use some sdk?

 

[adfree]

FTMA Combination Firmware is Service/Factory stuff... and looks like this:

You have only to click on the Icon... and enter Code on device like you would call...

@LucaBLK

You managed meanwhile your doubts?
If not you can look at Video 2... the second from here:

Maybe then more clear...

[LucaBLK]

Thanks again for help @adfree

video are really clear.

Unfortunately i soft bricked my watch just after the CSC flash step.
Everything went ok during transfer, or this is what ODIN said, but the watch was stuck in bootload screen and the wi-fi download is no more available.

Now the watch is in samsung for fix

Do you remember if you changed something in netOdin?

NOTE: I reccomend unchecking auto-reboot in the NetOdin3 program so it doesnt restart after flashing.

Something like this?


Best Regards

 

[LucaBLK]

Yes

I unchecked auto-reboot option

and then the screen i had trying to enter download wi-fi it's exactly that one without possibility to choose from any option.

After that i tried different ways to unlock the watch, also the procedure in the link you just posted, but without success.
