Problems in LTE activation (different regions)

Hello friends,
I'm from Brazil and I bought a LTE Galaxy Watch in Germany, exactly the same version (Sm-R805F) used in Brazil. However when I went to my mobile company to activate the e-sim it was not possible. When the system ask to read a QR code, in the mobile networks' activation process, a message of error appears ("It's not possible to conect this mobile"). Does anyone know why and how to fix it?

Can you check this Code...
Code:
*#1234#
Seems DIFFERENT Software crap exists... so different Profiles...
Code:
OXX
OXA
Check your CSC ...
OXA could be inside German Version... and OXX is maybe for Brazil...
Best Regards

Thank you very much!
I did it and the CSC is OXA (German version).
How can I change it to OXX?
PS: I did as they recomended here (https://forum.xda-developers.com/smartwatch/gear-s3/guide-how-to-change-gear-s3-r760-csc-t3784226 ) but theres no Brazilian code nor OXX.

OXX and OXA are """group"""
OXA contains minimum DBT CSC... for Germany
You can NOT change from OXA to OXX... because the config files not inside...
Your Link shows only way to change existing CSC inside flashed CSC file...
Example...
I have Firmware files... from OXX region...
Code:
CSC_[B]OXX[/B]_R805FOXX1BRI4_usr.tar.md5
You can unpack and extract with 7Zip... csc.img file.
Folder preconfig have 8 folderS with 7 CSC... DEF means Default IMHO...
Code:
BRI
TGY
VAU
XNZ
XSA
XSG
XSP
XSP is Singapore...
For the others I am tooo lazy... forgotten... use Google...
I have NO idea if it is an good idea to try to flash with netOdin such CSC files... or complete Firmware of OXX region.
Samsungs funny Security...
Best Regards
Edit 1.
I have tried to identify Brzil via Google search...
For me it looks no CSC inside for Brazil...
I have NO idea if SM-R805F is for Brazil market...
Edit 2.
Okidoki... Google search leads to this:
https://www.samsung.com/br/support/model/SM-R805FZSAZVV/
So looks like exists for Brazil... and you can see Sales Code ZVV it is in Product Code...
Code:
SM-R805FZSA[B]ZVV[/B]
IMHO 3 region groups... OXX OXA and ?
Firmware for Brazil seems not leaked... with ZVV inside...
Edit 3.
Firmware for SM-R805F for Brazil looks like this:
Code:
R805FXXU1CRK7/R805F[B]OWO[/B]1CRK7/R805FXXU1CRK7
So OWO is Region Code... for Brazil...
IMHO OWO package have ZVV Sales Code/CSC inside... for Brazil.
Edit 4.
My fault...
Code:
R805FXXU1DSC7_Tizen_4File_Multi CSC ([B]OWO[/B]).rar
Leaked and available...
But still no idea if this helps you... because dangerous to flash... Sams..g Security could prevent success...

Hi,
Can you list the available CSC's within the OWO version ?
I wasn't able to find it for download to check by myself..

@Nocturney
Region OWO Firmware contains these CSC:
Code:

ZTO

I've been reading the post, but I'm a little lost. I do not know what to do. I have a R815 Vodafone Germany version, and I want to activate it for movistar Spain, but I receive the error "It's not possible to conect this mobile". The data of my watch are the following:
AP: R815FXXU1ARH5
CP: R815FXXU1ARH5
CSC: R815FOXA1ARH5
With the SDB utility I have accessed a hidden menu on the watch and I changed the original CSC VD2 to XEC, or at least I thought so ... I think VD2 is Vodafone Germany, and XEC is Movistar Spain (the company that I have on my mobile phone). Samsung Pay works, but LTE is impossible to configure ("It's not possible to conect this mobile")
It is possible to get a different firmware and flash it?... or how can I get to configure an esim (lte) from movistar españa?

Hey guys, I was reading this post and I have a problem a little different of you.
I bought a Galaxy Watch from The USA, LTE version (R805U) but I live in Brazil, I went to the phone company (VIVO) to try able the LTE (eSim) function but they said to me that it is impossible because only the R805F works here.

Is not to you to do'it...
You need to call the operatório, in this case, Movistar and subscribe for the service and they activate the eSim...

Hi had same problem
Hello mate
I bought Samsung Galaxy watch when I was on holidays in Greece as in UK the LTE version was only with contract on EE. As I'm using Vodafone UK, I got the Qr Code for the esim but Samsung neither Vodafone could help me to make it work. Finally I make It work but my self, because my Samsung Galaxy watch is from Greek region I try to activate my Vodafone uk esim with a Greek sim network in my mobile device and it's worked perfectly, even when I put back my Vodafone uk sin on my mobile.
Hope that helps you.

Hi, could you elaborate on how you did that? I want to buy the silver LTE version from Hong Kong because that colour is not sold in Singapore, and it would be great if I could get the LTE working.

Hi adfree!
You are right:
A.- Old tricks are not valid for any GWA2 (including SM-R825F). Till now only combination firmware solution can change the csc
B.- Googling and Googling and no combination firmware available yet for this model SM-R825F... the one you found I'm almost sure is a mistype. The title is "R825F U1 combination" but the name of the file is COMBINATION-FT40_R825USQU1ASK2.tar.EF , so, no, it's NOT a good idea flash SM-R825U software into our SM-R825F ...
I'll keep googling to find if somewhere someone sells / gives us combination firmware for R825F !

SM-R825F
Have exactly same issue. I bought watch in Austria and try to activate e-sim from orange Poland. Does not work of course. Did you solve your problem already?
I have talk to samsung customer care and some service station, still nothing. Today they told me that in few cases service update to orange compatible firmware has been successful.

I still haven't resolved this problem. At a Samsung service center in Katowice, they told me that they could not install orange-compatible software.

Does the SM-R825FSKAXEO flash will change csc to XEO in both files prodcode.dat and active-csc-customer.inf or they will remain unchanged?
Otherwise only combination firmware is the solution, am I right?
Samsung service stations in Poland are completely not interested to help in solving our problem however Samsung support says different...

Two new combination firmwares did show up on easy firmware web page. Does in not matter which we use to flash to have access to edit csc responsible files? Does the stock firmware code or/and region is not important once it is flashed by combination firmware?

Hello Guys thanks for your great informations and work and help.
I already changed a CSC's GWA2 R820 to the KOO CSC then it was possible to update to the latest FRM and also to the TIZEN 4.0.0.7.
Now i get a GWA2 R825F (XEF) i wanna ask you please if the process still the same? coz i saw that the firmware is old and still in 4.0.0.6 ....... is there a tuto on how changing the csc to another one to be able to update latest FRM?
Or maybe the latest firmware for the R825F is still 4.0.0.6 ?
Thanks for all answers.

I have sm-r825f with Tizen 4.0.0.6 but there is nothing I can do without combination firmware. However to play to much a bit afraid to do not brick the watch forever.... ?

Would like to inform I have checked all the firmware available on easy firmware under R825F but these are just R825U firmware with name changed. upon downloading the file is a copy of U variant. I almost bricked my watch so NO right now not even a paid site has combination firmware for R825F model.!!
Do keep me in loop if someone finds it.

HI AdFree!!
Justr wanted to know if you can tell under which multi csc will I find INS (india) code. Its not in OLB.
Also the Australian version is SM-R825FSKAXSA
whereas Indian is SM-R825FSKAINU
only CSC code changed in the model number.

INU is inside OXX region package...
I nowhere saw OXX package leaked...
XSA is inside OLB...
I have no files to check... but it seems only 1 CSC/Sales Code inside...
So this is NO multi number 1...
Maybe Indian Version contains also only 1...

Can somebody post Odin screen of SM-R825F?
sboot.bin Bootloader files have this text string inside:
Code:
SM-R825F[B]S[/B]
Question for me... Bootloader shows SM-R825F or SM-R825FS ?
Thanx in advance.
Best Regards

Still waiting for confirm... Odin screen shows?
Code:
SM-R825F
or
Code:
SM-R825F[B]S[/B]
For instance no idea what is inside:
https://easy-firmware.com/index.php?a=downloads&b=folder&id=46392
Code:
COMBINATION-FT40_R8205XXU1ASL2.tar
COMBINATION-FT40_R825XXU1ASK3.tar
.
.
Few more...
Normally easy check if it is for SM-R825F WITHOUT Flashing and risk...
sboot.bin Bootloader text search...
But it is important to know what Odin shows...
Sams.ng made some funny unified cr.p... FCC ID is:
A3LSMR825
Maybe they unified some more things...
I mean Easy Firmware are NO noobs...

I used method B
The csc it gave is XSG meaning UAE right?
Can I switch to another csc to get the OTA?

UAE... maybe... use Google to be sure...
Sorry I am from Germany... and my brain is limited to remember 80 CSC...
But with your result you can create Links:
http://fota-cloud-dn.ospserver.net/firmware/XSG/SM-R820/version.xml
https://doc.samsungmobile.com/SM-R820/XSG/doc.html
Now you see... your active CSC is limited to this Version as latest:

CSC changing is for instance here:

If you need mandatory Samsung Pay...
Maybe change to XAR or other CSC disable your Samsung Pay...
No idea I have no Crystal Ball... OWN RISK!
Maybe wait "few" dayS more...

Impossible to update my Watch Active

Hello. I had an OXE CSC on my SM-R500 (Tizen 4.0.0.7) and I wanted to get a XEF CSC. I flashed the watch with R500XXU1BSB7 with Tizen 4.0.0.3. But, I can't install the update (R500XXU1DSL1) with the in-app plugin. When the update is downloaded and transferred on the watch, I start the installation. But, few seconds later (close to 96%), the installation progress jumps to 100%, the watch reboots and I have an error message who tells me the watch can't be update and asks me to go in a Samsung Customer Service.
Who can help me please ?

1 way is to use netOdin and flash self:

Be sure you take Firmware for SM-R500.

In case of SM-R500 this is wrong... we have only OXA Region with all CSC / Sales Codes inside...
So IMHO something is not 100 % correct...
IMHO check your priorites...
All I know about Samsung Pay is...
Nobody can be 100 % sure... because few Cards not accepted... Region blocked etc... blabla...
Best Regards

I'm with the same problem.
After done the firmware downgrade, I activated the Samsung Pay (but isn't works), and i'm impossible to do firmware upgrade via app.
Do you solve your problem?

and i'm impossible to do firmware upgrade via app.

I have 4.0.4 R810XXU1CSE1. My Watch was bought in USA, so when I came back to Brazil the Samsung Pay not worked.
So I done the downgrade to activate Pay and worked. But, now i'm not able to add card and to do uograde too. LOL =/ . I didn't use the DSL1 because isn't possible to chagem CSC in 4.0.7.
What do you recommend?

But after CSC Change you can use DSL1...
What ever you used,, will not changed by Firmware Update...
If you not change every 5 Minutes CSC...
IMHO you can flash DSL1...
And if you have no problems with R810XXU1CSE1... you can still use CSE1...
Depend on your flavor... on your needs...
Maybe try DSL1 with Samsung Pay... maybe more luck as Samsung Pay newer Version...
NO Garantie...
S Pay is Security crap and secured by Samsung by some funny and """mystique""" Voodoomagic and seems not all Cards supported.. real or virtual Cards
IMHO 1 Security Wall is Phone... Country Check...
Tooo many ?
No easy solution.
Best Regards

Great!! So I'll try flash to DSL1, and follow if will the nexts updates and S Pay will works too.
In time, via my serial, is this possible to check what was the default CSC of my watch?
Best regards.

R815F Change CSC with tizen 4.0.0.7

Hello there,
I am trying to change the CSC of my watch to enable samsung pay on my watch. Since tizen 4.0.0.7 Samsung has patched to old method, and to my understanding I have to install a combined framework in order to change the CSC as mention here
https://forum.xda-developers.com/smartwatch/galaxy-watch/changing-region-galaxy-active-2-t3983895
However I could not find a combination firmware for R815F only R815U. While I am fairly certain that it should be interchangeable as it is mentioned here with R825F and R825U, but I don't want to risk it.
Does anyone have experience with changing the CSC on a R815F using the combined firmware method?

So trick still work with SDB...
