Galaxy Watch Active Latest Firmware files - Samsung Galaxy Watch

Hello,
I see there is an update with build number: R500XXU1DTG2 for the original Galaxy Watch Active (SM-R500).
Can someone tell if it improved anything?
Also, since I have already flashed other firmware for CSC change and it didn't come to me via OTA, where is the best place to get the files for flashing?
Thanks in advance.

[Q] Flash back to stock ROM

HI
I have a UK Vodaphone SG Note 2 that I rooted a while back but cant remember what root I used
I did mange to get a Download message to appear on the screen when all three buttons were pressed the other day and I think this is the ODIN? down-loader
My issues is finding the right ROM. I have found two on the internet
N7100XXDMC3
N7100XXDMB2
But my phone says that it has:
N7100BUDMD1
The two above seem to be from March this year and I can remember that before I rooted I did up grade from Android 4.11 - 4.12.
So how do I find the exact baseband version as there is no sign of a download for:N7100BUDMD1
Cheers in advance for any help

It shouldn't matter what firmware you download as long as it is for Vodafone UK. Provided you return to full stock, you'll be able to update to the latest firmware provided through Vodafone. Baseband name is different from firmware name afaik. If you can bring up more info on the firmware, they should also show baseband/modem version too.

Note, there are no official 4.2.1 roms. Samsung confirmed it will skip it straight to 4.3 and there only is the leaked firmware as of yet

Cannot update after downgrading the R800 4.0.0.7 to 4.0.0.4 to switch the CSC

Hi guys.
After downgrading my Galaxy Watch to 4.0.0.4 and changing CSC to BTU so I can have Samsung Pay i cannot get it to update again to 4.0.0.7.
In app on phone when I go to software update it says it is up to date. Is there any way to force it to update or just wait until it updates on its own.
Nobody answered so I suppose I have to manually flash new firmware. Will my csc change to BTU stay whichever build of new 4.0.0.7 firmware I flash?
So it's solved. I upgraded back to 4.0.0.7 DTG1 and csc change stayed. Now I have samsung Pay and latest firmware.

Hi
Why didnt you just stay on 4.0.0.7 and did the csc change there?
Mine was actually on the newest firmware but after i did the csc im now on 4.0.0.7 and i cant update to the newest. Can you update to ver 5?
CSC change over adb doesn't work on 4.0.0.7. So I had to downgrade and then upgrade again. There is no ver. 5 for R800.

Hi ChmT, thank you for your post.
Even I am facing the same problem.
I downgraded from 4.0.0.7(one ui 1.5) to 4.0.0.4, changed the csc successfully, enabled spay, but now not getting any updates. It says software is up to date.
Can you please help me with the requires files to update back to 4.0.0.7, or atleast links to those files?
Thank you.

Firmware to downgrade SM-R805F

Hello everybody!
I need the firmware R805FXXU1ESI1 to downgrade and change the CSC of my Galaxy Watch, but unfortunately I only find it in Easy-firmware, and I don't have an account there:
R805FXXU1ESI1 Tizen 3File | Easy Firmware
easy-firmware.com
I need this version exactly, because my region is ZTO and I need this base firmware (OWO).
Thank you very much in advance.

As per my understanding, I have to follow these steps:
1. Flash combinational firmware
2. Change CSC using SDB commands
3. Flash stock firmware
4. Install samsung pay
5. Repeat steps 1-3 to change CSC back to the original so that i retain mobile connectivity
@galaxys I have the same watch model but with Tizen 5.5. Would the same old firmware work with my watch also?

Thanks for your early reply otherwise i was thinking of giving it a try.
BTW i found that dialing *#272*IMEI# also change the CSC but did not try because people here are going for flashing firmware due to some reason only. Do you know why shouldn't it work on galaxy watch?

It may be a Samsung thing for not working, but haven't played with changing CSC...
@galaxys @adfree I could not find Tizen 5.5.0.1 firmware for SM-R805F anywhere on the internet. It was released on 15th march 2021.
Is it not available yet? I am waiting for it...

Change region to Active 2 Model SM-R835U

Hi guys!
I want to change the region to my active 2 LTE from US to Mexico so that I can use my Mexican carrier. I got it thinking it was globally unlocked but it looks like it's locked to the US.
I've seen some tutorials but they are for older versions (Tizen 4). This watch is on Tizen 5.5.0.1.
Can anyone please help me out with this?
Thank you very much
Looks like Mexico is OWO Region package... with CSC:
TCE
Step 1.
We need Combination Firmware...
Attached is slightly "modified"... only removed folder + 1 file...
Step 2.
We need OWO package of SM-R835F...
Best Regards

Thanks for your fast reply! I somehow managed to have Samsung Pay installed and get the latest Tizen 5.5.0.1 installed! I will share my experience in case someone else is having issues with updating Tizen after downgrading !
Here is how it worked out for me:
First I downgraded my Tizen OS with Odin to the following software:
R810XXU1CSI1 Tizen 4.0.0.4 ( Downloaded from here: https://disk.yandex.ru/d/TPWpD1y1CE6Sig )
Then I used the SDB kit to change my region to XAR. ( You can search how to change the region on your watch in the XDA forum search box ).
Then I googled Samsung Pay watch plug-in apk. ( Downloaded from here: https://www.apkmirror.com/apk/samsung-electronics-co-ltd/samsung-pay-watch-plug-in/ )
Installed it - it showed on my watch and in my Gear App.
So far so good.. but It didnt want to update to Tizen 5. It was stuck on Tizen 4.
So I flashed this firmware with Odin: R810XXU1BSA4 Tizen 4.0.0.1 ( Downloaded from here: https://mega.nz/#!vg8k3AbA!zcUGtSJPzEdo_PKs_8_u0M6evKXfmQysfK4cZHOkJW8 )
And I managed to update the watch with all the updates and Samsung Pay didnt get removed .
P.S. - This is how it worked out FOR ME!! You can try to change the region with the last firmware - it might as well work out for you too !
I hope I helped with my experience. This is firmware only for the SM-R810 watch model! If you flash it on another watch it might get bricked !
And again thanks to @adfree for replying !
