Looking stock firmware for SM-R805F

Hi everyone,
I just recently got a SM-R805N (Korea LTE ver) and want to change its region.
However the CSC variants in the stock only contains Korea telecom (as mentioned in the CSC thread by ecoco1)
I am trying to use the old fashion way: flash in the combination firmware, switch the CSC and then flash back to stock, in which, the CSC I am looking for is in SM-R805F version
However, I cannot find any free source for SM-R805F firmware online... all those available , also in this XDA forum, is only for bluetooth version.
Would anyone in XDA able to source the R805F firmware? (best to have both combination & stock?)
Thanks a million

Caution.
Since Gear S3 it is NO good idea to flash wrong Firmware nor wrong parts... to LTE variants...

Additional info...
Not tested what happens with CSC only... BUT be sure it is not less dangerous... because partition PIT is inside CSC and netOdin AUTOMATIC write this file to device...

Study offline...
You can extract files with 7zip and compare...

Thanks adfree, but its too late... I have already bricked my brand new galaxy watch...
Now the watch wont go into any mode below. All it does is have a flash of horizontally line screen, consistently.
continue
factory command
recovery
download (wireless)
Tried the method "press 2 seconds, release 1 second" does not work, think it corrupted the partition.
Only mode still work is "download" which shows the screen correctly. What make it worse is I reset the watch before doing this and forget to turn off activation lock (but I have my own user name and password, think that does not make it worse then?)
Appreciate if any idea on how to tackle this... am already thinking about buying the usb connector for odin flash...(hopefully something will make it work again...)

Suggestion, if you want try it self at home....
Look into this post:
https://forum.xda-developers.com/showpost.php?p=78545468&postcount=74
Look into Video...
You can also click around this Thread... to see diffferent "solutions"...
Security prevent netOdin use... IMHO no way without USB to flash again.
If you have POGO Connector... Odin...
Then try FIRST to flash SM-R805N...
I see at this time it is not leaked...
So you need luck to flash SM-R805N Firmware...
Hopefully Warranty Void will still:
0 0x0000
Seems 3 SM-R805N Stock Firmware leaked:
Code:
R805NKOU1ARK8
R805NKOU1ARJ6
R805NKOU1ARHJ
You can PM me... if you need Help with POGO...
Best Regards

Sent you a pm thanks very much, i have not yet able to watch the video as im at work, but i think i need the items below:
R805N stock firmware
POGO Cable for usb connection
anything else would i need?

Thank you @deadman96385 for the firmware
Hi adfree, here is the photo of the "Download" screen
Now i need to get my hand on the cable to try it out...

Thanx for Photo. :good:
Good:
A
SM-R805N to see...
So sboot.bin is not overwritten...
B
Warranty void still 0 0x0000
So Knox not dripped... BUT you have to wait for final result after Repair Flash...
Not so good = IMHO bad...
Reactivation Lock is ON...
This means MORE f&%ing Security...
As "we" have only Stock Firmware...
If no luck then also Warranty Void Value will change... maybe.
P.S...
partition.pit aka PIT is 1:1 same between SM-R805F and SM-R805N... except the RSA 2048 Signature crap at the end of file.

thanks... I should be able to get the POGO wire mid next week, will update you the result....!

My Galaxy is back alive! Thanks everyone in this thread. Tested the following:
Install R805N firmware: Download mode: Works
Install R805F firmware:
Download mode: PIT fail instantly, without install
Download (Wireless): Able to complete the install -> Fail warning in red -> Bricked
Tried for combination firmware, or CSC only, same result
Guess I will never have chance to change my CSC then...? (Unless there is a combination R805N available which has all CSC countries inside?)

no i am not able to change, as mentioned above, the original firmware does not have other CSC included, flashing any other firmware will brick the watch

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.

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...

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!

Hi ,

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.

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:

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.

Looking for R835F/R835U FT55 Firmware to change CSC

Hi guys,
I want to change my GWA2 40mm LTE (Unlocked) US (R835U) Tizen 5.5.0.1 CSC to something working in Canada. In the first step, I need the firmware files. I appreciate it if someone could share them with me and other users. An expert member told me that I need the following files:
COMBINATION-FT55_R835USQU1ATK1 (https://easy-firmware.com/index.php?a=downloads&b=file&id=313912)
or
COMBINATION-FT55_R835USQU1ATJ1 (https://easy-firmware.com/index.php?a=downloads&b=file&id=308035)
I'm also not sure whether I will need the "R835FXXU1BTJ1_Tizen_4File_Canada (OYV)" as well or not later. (https://easy-firmware.com/index.php?a=downloads&b=file&id=327323)
Thank you.

Combination firmware FT55 for Tizen 5.5...
This is "mandatory" to have full access to device for lowest Security...
Bootloader sboot.bin is protected... and mandatory in the chain of trust in FOTA chain blabla self check blabla Security crap bla bla...

forum.xda-developers.com
Product Name you should see SM-R835US instead SM-R835FS
To have chance to full convert... your goal is also to replace sboot.bin...
To see as final result:
SM-R835FS
Then chance to have valid FOTA chain for updates over the air...
Combination Firmware is step 1.
Step 2...
If device is still allive... after FT55 Flashing attempt...
You need Stock Firmware for Region with Cannada...
http://fota-cloud-dn.ospserver.net/firmware/XAC/SM-R835F/version.xml
I hope XAC was for Cannada...
So you see Region OYV

So if I've understand well, step 1 is finding "COMBINATION-FT55_R835USQU1ATK1".
I attached my watch download screen.
@manikar has installed Canadian firmware on R825U (44mm US) before. I'm not sure how he has done that. His post is on May 2020, so it should be FT40.
