What's the difference between the 2 firmware u shared ? Whats a combination firmware ?

Combination Firmware is Service/Factory stuff... and also 1 way to change CSC...
But ignore this... for now...

Strangely I don't see any official firmware named bsd5 or Asad. It's because these are modified firmware for sm-r500 ?
I have downloaded BSB7 firmware. Is it all right ?

Is there any risks to flash a new firmware on my watch active ?
The thread you sent me to use netodin is so hard to understand.. could I ask you to make me a detailed flashing process of the firmware with netodin ? It would be so nice
For example I don't know if I have to modify something in the firmware file so it choose the good csc I want...

I used NetOdin to flash the combination firmware, change the CSC to TGY, and flash to R500XXU1ASAD yesterday. So If I flash to the latest R500XXU1ETI1 firmware now, would it keeps the previous CSC that I've changed?

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:
R800XXU1[B][COLOR="Green"]CSE1[/COLOR][/B]
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.

Then it seems OXA region.

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.

Changing Galaxy Watch SM-R805F 46 mm CSC with Tizen 4.0.0.7

Hello,
I try to change my CSC to be able to activate the eSIM and Samnsung Pay,but i'm unable to do that in sdb (it says launch_app csc-manager.csc-pre-configuration that is successful but on my watch it doesn't show the CSC menu).
Is downgrading my only solution and if so , where can i find the firmware because I can't seem to find anything on SamMobile?
Thank you

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.

netOdin is not 100 % riskfree.

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

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!

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.

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?

Now you see... your active CSC is limited to this Version as latest:
Code:
R820XXU1BSJ6/R820OXA1BSJ6
CSC changing is for instance here:

WARNING!
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...
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...
Best Regards
