XEO in csc.img is Orange Polska. Can change from DBT to XEO?

IMHO you have 2 tiny problemS...

Old trick IMHO not work... only idea NOT tested yet...
Because I have no SM-R825F...

After short check on my HDD... then clicking weired thorugh Internet...
Seems no Combination Firmware leaked...
You can find something like this:

NO good idea to try SM-R825U Combination Firmware on your SM-R825F...

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?
Best regards to All of you having same issue.

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.

Code:

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...

Samsung Pay for SMR800 Tizen 4.0.0.7

Hi all can somebody help installing Samsung Pay for India
I connected watch through sdb connect and when i run
command launch_app csc-manager.csc-pre-configuration it says successfully launched but nothing happens on my Galaxy Watch verion R800XXU1DSL1 tizen 4.0.0.7
Used SDBstarterKidv1

Downgrade...
https://forum.xda-developers.com/smartwatch/galaxy-watch/update-gw-r800-t3936370
Simple use older Firmware as DRK2... DSL1...
If you choose XAR for USA... then choose this Firmware:
Code:

IMHO here SDB Commands still work...
In theory somehwere Thread or Post...
In newer Firmware like DSL1 Samsung increased Security...
Best Regards

After downgrade and changing the region to enable Samsung pay.
If I again update to the latest firmware version will the Samsung pay still be there?

Yes, if you changed the CSC to get Samsung Pay, it will still be there after an update. As far as I know, the availability of Samsung Pay is CSC bound, not firmware bound.

Hi guys, I'm from Brazil, and my FW is the R810XXU1DSL1.
I need to change the csc to ZTO... same problem, nothing happens.
Can some one help me?
What downgrade do I have to do?

You need to downgrade to any firmware older than DSL1 with NetOdin, as described elsewhere on this forum. Then changing the CSC will work.

Hi. I have the same problem. I'm now going to downgrade with the procedure in this topic.
I just have a doubt about which firmware I should use. This are my current info:
Watch: SM-R800
One UI: 1.5
Tizen: 4.0.0.7
Current FW: R800XXU1DSL1
Knox: 2.4.0
Bought on USA
Need to enable Samsung Pay in Brazil (I believe need to be changed to ZTO)
Can someone please which firmware I should try? First and second options?
Thanks.

On phones, usually downgrading can result in brick.
In the galaxy watch this does not happen can I downgrade to a previous version without fear of it happening?

Phones have USB cable for Emergency Flashing.
Samsung Watches is bigger problem if you kill the """WiFi Security chain"""...
You have not USB cable for easy second attempt.
And the LTE Watches makes more trouble... if you doing something wrong or simple out of luck.
You asked about worst case...
netOdin is not 100 % riskfree.

No risk no fun. :angel:

Hi, I have SM-R805F bought in Czech rep. Can I use these instructions for downgrade my firmware to change my region (I want Samsung Pay)? I have saved my eSIM in my watches now - after flashning it will stay there or will be deleted? Thanks a lot

@ohajo3
Yes you can. Do not reset networks after flash during setup. Esim will stay.

I changed my CSC to Australia to get the Samsung Pay but this disabled VoLTE on my watch. I m now not able to call or receive any calls. I m from India. Watch was originally purchased in Australia.
During this process I was prompted for update which I did and now I m stuck with 4.0.0.7 version and no way to change the CSC back to INU using shell access way.
Only way now looks to use the combination firmware and Odin. But not sure where to find the Combination Firmware for SM-R805F LTE version.
Anyone or @adfree can point me to right direction to get the right required binaries ?
My device details
AP : R805FXXU1FSL4
CP: R805FXXU1FSL4
CSC: R805FOXX1FSL4
LTE version.

Can anyone help with the right binary I should use to downgrade?
These are my device details:
AP : R805FXXU1FSL4
CP: R805FXXU1FSL4
CSC: R805FOXX1FSL4
LTE version.
Not able to find combination firmware for this version. Not very sure which one I should use.
Thanks in advance.

@madono
You wish to have India INU?
http://fota-cloud-dn.ospserver.net/firmware/INU/SM-R805F/version.test.xml
IMHO seems INU require OXX package...
Here are 2 OXX packages:
https://forum.xda-developers.com/showpost.php?p=79644543&postcount=1
According to DBT list... they are before Tizen 4.0.0.7
So please try these 2 firmwares... with the old method to change CSC...
So IMHO no Combination Firmware required...
Only downgrade...
Best Regards
Edit 1.
Sorry, my fault...
Links expired.
Edit 2.
Oh, totally forgotten...
Latest FTC1 for OXX region is here:
https://forum.xda-developers.com/showpost.php?p=82893207&postcount=55
INU inside this OXX region.

@adfree Thanks for the links! I m downloading it right now. Speed is slow, not sure if I will be able to download it in one go. Is there any expiry for this download link? If I m not able to download today, will try tomorrow again.
Another question for downgrade, do I have to choose all four files , namely, BL, AP, CP, CSC to downgrade?
I have not done a galaxy watch downgrade before so wanted to be sure not to mess it.
I actually wanted to have Samsung Pay and LTE enabled. It was working fine using Australia CSC code but my Phone operator recently changed calling only on VoLTE. So i was not able to receive calls or call anyone. Only internet was working using AU CSC.
Now it seems I have to choose between calling and Samsung Pay. SP is not officially launched on Galaxy Watch in India. Only on smartphone it is allowed. Not sure why.
Thank you once again!
Regards,
madono

Hi @adfree,
I downloaded the firmware from the link. Today was bit hard day at work so not trying to update watch.
Will try it out with fresh mind tomorrow. Just need couple of things cleared before I try it.
1. In firmware download steps, it is mentioned to only use BL, AP, CSC file?
Downloaded rar has 4 files. Is this fine?
And final one this is my current watch status
AP : R805FXXU1FSL4
CP: R805FXXU1FSL4
CSC: R805FOXX1FSL4
Watch is LTE model.
I m good to go ahead with said firmware?
@adfree please review, don't want to mess this one. I know there is always risk but want to use correct firmware.
Thanks for the help!

Finally was able to downgrade to 4.0.0.4 and watch did not explode
This link has 4.0.0.7
https://forum.xda-developers.com/sho...7&postcount=55
After download I was still on 4.0.0.7 and looks like my CSC was still pointing to AU
I used this link to downgrade : https://www.file-upload.net/download...E3_OXX.7z.html
Then SDB command to change CSC from AU to India
Thanks to @adfree
One thing I observed that my eSIM was not reset. I was expecting it will be removed when I downgrade. Looks like it is left alone in this process.
Not sure if there is any way to enable Samsung Pay without changing CSC. Missing SP very much in current time.
Regards,

Please concentrate... focus...
IMHO I thought you wish to change CSC...
So IMHO 2 FirmwareS needed...
A
For downgrade to use old SDB Command for CSC change...
B
I gave you latest FSL4 for OXX region...
Now is up to you to manage.
IMHO I gave you all infos + files + links...
Please mercy... I have not unlimited time and energy...

Did I correct understand:
To change CSC by old method (with SDB) it is needed:
1. Flash with Odin all 4 files (early Firmware)
2. Change CSC with SDB
3. Install Samsung Pay
4. Flash with Odin all 4 files (latest firmware) back to FSL4
and Samsung Pay will stay?

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.
If you need help with netOdin... look at Youtube or look here:

Good Question.
XEF is inside this package... you can check by decompress and extract files from csc.img with Tool:
Code:
7Zip
I had an OXE CSC
Click to expand...
Click to collapse
This looks to me as no valid CSC...
OXE I saw only as Region Code...
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?

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?

Downgrade Firmware...
In other words use older Firmware...
So trick still work with SDB...
