Hi guys,
I really need some help please.
I have the US model R845U LTE and I'd like to change the CSC to ITV (Italy) to get the latest updates as mine is stuck to R845USQU1BTK2.
I am following the procedure of Technoproz but I need to be sure that I use the right files.
I downloaded the combination firmware COMBINATION-FT55_R845USQU1ATL2.tar. This is the right one, right?
I have a doubt on which stock firmware to use. Should I use the R845USQU1BTK2_Tizen_3File_CSC (OYN)?
Or should I use the firmware R845FXXU1CTJ5_Tizen_4File_CSC (OXA) which is the Italian one?
Thanks in advance for your help!
Are you sure there's an update for your watch on CSC ITV? This page gives the firmware history for model R845U on XAR, but on ITV it gives an error.

First of all, thanks for helping.
That's exactly my doubt.
On CSC ITV they are at the R845FXXU1CTJ5 so, to answer your question, yes there is an update but it's for the R845F, not for the R845U.
So, do you think that I can flash the firmware for the 845F after changing the CSC to ITV?
Thanks

I would be very reluctant in flashing firmware for another model on your watch. There's a good chance you'll brick it.

Yep it makes sense what you say but...my concern is...if I flash back the BTK2 after having changed the CSC to ITV...what do I gain?
Will I get the updates of the ITV region or not?
Cheers
Does anyone know if it's possible to downgrade from tizen 5.5.2 to 5.5.1 ?
I want to change my watch 3 CSC but i couldn't find any firmware in 5.5.2 which my watch currently on it so i want to downgrade to 5.5.1 then flash combination...

I'd expect that since that webpage with firmware history I mentioned gives an error for R845U on ITV, you won't get any update after changing the CSC to ITV. So you won't gain anything if I'm correct.

And I managed to brick it.
I tried to flash the combination firmware downloaded from easy firmware and it failed.
Now the watch doesn't reboot and I don't know what to do.
Hopefully Adfree will be able to help me.
If you have any suggestion please feel free to let me know.
Thanks
I have to officially give a big thank you to Adfree for his help.
We managed to fix my watch and now I have a full ITV version...moving from the original R845U to R845F.
Everything is working now BP, ECG and Samsung Pay.
Thank you Adfree!
I'm glad it worked out in the end. What would you recommend to other users wanting to swtchifrom R845U to T845F?

Apologies for reverting late!
So, this is what I did to change my R845U into an R845F:
1. Installed the combination firmware with netOdin
COMBINATION-FT55_R845USQU1ATL2_clean_v1.zip
drive.google.com
2. with the pull/push commands via SDB I changed the
a. PRODUCT CODE from SM-R845UZKAXAR into SM-R845FZSAITV
b. CSC from XAR into ITV
3. Installed the stock firmware CTJ5
R845FXXU1CTJ5_Tizen_4File_CSC (OXA).zip
drive.google.com
and voila'....the GW3 became fully Italian.
Then the watch will update itself via OTA to the firmware DUA4.
At this stage the BP and ECG widgets are present on the watch and the last step is to install on the phone the SHM app (version 183) which can be found on the other thread (by Dante63).
And all is working.
Couple of things:
- I am leaving those links active for a week or so. I bought both above firmware from Easyfirmware but I'm glad to share them with the community.
- I am not responsible for any bricked watch As usual, do these things at your own risk
- A huge thanks to Adfree for his help!

@[email protected] Is there a Mac version of NetOdin I can use for this?

Hi!
I have a couple of questions:
1) My software is currently R845USQU1ATFE. Would I be able to use your file COMBINATION-FT55_R845USQU1ATL2_clean_v1.zip?
2) In your step 2a using sdb, how did you manage to change from R845U to R845F? Basically Is there a way to check whether my software has CSC code TGY? I assume if R845U...ATFE already has TGY, then all I have to do is sdb pull/push for TGY. Is that correct?
Any help is greatly appreciated!

Oh wow, at first I thought it was easier than this! Anyway thank you so much for the help, I would really like to try this and finally change my watch to use it in all its features. But I can’t hide that I’m a bit anxious to do something wrong and then ruin my watch forever. Maybe there’s a YouTube video that guides you in the process?
Anyway I’ll let you know if I’ll succeed in this, thank you again!

Used to be a bit easier when I did the region change for the S3 gear. Gotten a bit more complex.
First line in my post above, I've linked the youtube video from TechnoProz.
Watch (no pun intended) the video.
Do it only if you are comfortable.

Ok I’ll go watch it! And I went checking on the Samsung website for the firmware, and if I open that page it shows me two different firmwares, the first and most recent is:
Build number : R845FXXU1DUA4
Tizen Version : Tizen 5.5.0.2
Published on : 2021-02-22
And the second is:
Build Number : R845FXXU1CTJ5
Tizen Version : Tizen 5.5.0.1
Published on : 2020-11-24
So my question is, as the firmware I need is the second one, so not the most recent, if I change my watch to that firmware then will I be able to update my watch with the future updates? Or it will remain stuck in that specific firmware?
Sorry if this is a stupid question, but as you can see I’m not really into these things!

Stick with the 2nd update that was successfully done by @[email protected]. Once completed, you should be able to do an OTA (over the air) update to DUA4 directly. Technically, you can but rather follow what was done successfully.
Not a stupid question.
The watch is relatively new and not many info for the R845U version in particular. Takes time to really put things together. Big thanks to @Kebez & @adfree to start it off,
I know there are guides out there, but I seem to get stuck with all of them.
This one gave me a version of Odin for Mac, but then it turns out you need Heimdall, which only works with "Microsoft Visual C++", which only works on windows.
Download JOdin3 for macOS, Linux, and Windows [Odin for macOS]
Download JOdin3 for macOS X, Linux, and Windows OS - Latest version. JOdin is also known as Samsung Odin for Mac OS and Odin for Linux.
odinflashtool.com
So I tried using a friend's PC and finally got Odin, but that was as far as I got.
This one mentions "pull/push commands" but doesn't explain what they are or how to use them.
CSC Change - Model R845U
Hi guys, I really need some help please. I have the US model R845U LTE and I'd like to change the CSC to ITV (Italy) to get the latest updates as mine is stuck to R845USQU1BTK2. I am following the procedure of Technoproz but I need to be sure...

How to Change your Samsung Galaxy Watch Region! – Roonby
After the updates of Samsung Galaxy Watches with the latest Firmware, there is a bit problem, where users can’t change their region. It is probably a security measure by Samsung. However, if you are interested in messing around your Samsung Galaxy Watches and wanted to change its region...
roonby.com
The watch was purchased in Italy. Apparently blood pressure and EKG are supposed to be available in the EU as of a month or two ago, but I don't see them. Samsung Pay popped up, but it only offers the option to apply for a Samsung card, which it then says "isn't available." No option to add existing cards.
When I first got it, I set the location to France. I tried wiping it and setting to Germany, but once it was set up again, it was clear it was still set to France. I'm guessing this has something to do with my phone recognizing it once connected? I'm open to changing it to any country where all features work, but ideally Germany or the US.
How did you try to choose Germany as the new region? In your case (you were able to choose a region at first use) it should be possible with a factory reset.

It let's you choose from a bunch of EU countries, but you can't choose just anywhere.
Hello,
I used this method (thx TechnoProz) to change region on my smartwatch active 2 to Spain and it works fine:
Also I have followed his steps to install ECG and BP, but BP doesnt work, monitor app says watch not compatible...
Anyway I want to know some quick way to know if smartwatch is rooted (some menu or command). When I used the procedure to change CSC, I used command "sdb root on", change the 2 files, and after we download stock firmware in the watch. But unroot command was not done.
I read in another post that after this procedure the watch is not rooted, but I am not sure. Can you confirm that? Some clue to know if a smartwatch is rooted or not?
I ask this beacause in some place I read that rooted smartwatches can be a problem to samsung download apps, maybe it is the reason why BP and ECG was not present in the watch after change to Spain region...
Thankss in advance!
Just bought a new GalaxyWatch5 in China, but it fails to connect to my Samsung phone due to "isn't supported on this phone" issue.
Does anybody know how to fix it?
Are you sure its not a knock off? Are Regions same for watch and phone? Factory reset watch and try again. If still a problem contact seller and/or Samsung support.

The watch are newly bought in China. I'm not sure how to check the region on the phone, but it was bought and used for some time in Russia.
Update: Support operator claimed that Chinese version GW5 are not supported due to the software features caused by restrictions on Google services...
if yr watch is china version you can,t pair phone with google services. the phone paird with watch witch disabled google service.
or try to flash your watch to other regions to pair phone enabled google services witch disguised sim Operatin (remove sim card not sure).
i prefer 2 but will take risks.
in general it is a complicated operate.

Hello all.
My S20FE (SM-G780F) has not updated from OneUi 3 and Android 11. It always says that I'm using the latest software. I've tried factory resetting the phone and using Smart Switch to no avail.
I'm in the UK. Never lived anywhere else. I reside here permanently. It's where I bought my phone brand new.
I checked the service provider software version and it says ZT0/ZTO,ZTO/EUX . However, when I use the dialler method to check the same information it says the CSC is BTL3.
I researched and ZTO seems to refer to Brazil. I've never been to Brazil or anywhere in that vicinity so I don't know why it says ZTO as the service provider information.
Could this be why I'm having issues updating? If the phone thinks it's Brazilian then it would stop me updating if I'm in the UK? Is that correct?
Samsung suggested I send it to them to flash the drive but they require a proof of purchase and as I bought the phone over 2 years ago I can't for the life of me find the original order email.
Just for clarification the phone has never been rooted or modded and all software etc is "official." I've looked into flashing the software with Odin. Would I need ro download the update file for the CSC my phone says it is or for the CSC it should be? Do I only download the latest update or would I have to stack them and download all the previous ones my phone missed too?
Please help before I tear my hair out.
flashing the phone yourself with Odin is very easy, there are dozens of YouTube vids to get an idea from. actually downloading the firmware is more difficult.
whoever sold you the phone is who you should be angry at, it obviously wasn't intended for use here. let me know if you want help flashing!
Same thing happened to my Mom's phone (a Galaxy A series device).
Use this guide and manually flash the latest firmware.
