Maybe other users have Crystal Ball... I have no Crystal Ball.
Easy things to do... to find usefull infos...
A
We type funny Code into our Watch:
Code:
*#1234#
This Code is IMHO working in Samsung Phones etc more then 10 years...
B
Active CSC...
User described here 1 easy way:
https://forum.xda-developers.com/showpost.php?p=81190183&postcount=31
Their are few more ways to identify the active CSC in your device...
Methods like ... I can smell... or I thought I bought it in... are less helpfull in case of identifying what is important for "Firmware update" questions...

TMB Lies.... Again
Update 2/3/2020:

UI graphical element changes (UI 1.5)
S Health enhancements (Outdoor swimming trajectory & distance enhanced. Auto-session calorie logic added. Heart rate calorie calie logic added.)
Updated to Bixby 2.0New watch faces
This new version is NOT yet available, don't know who keeps updating their "latest version" page, but they should be fired... ?
Cost me hours of phone time with TMB support then Samsung support, only to find out here that Version R805USQU1CSL2 is still in r&d, not ready for distribution yet... And so we wait. ?
Thank you very much for the information.

Thank you for the link, I've downloaded it.
T-Mobile service, at least the people I've spoken to here in the USA don't seem to know much about the Samsung Watch... At all.
I'll wait a bit longer for answers to questions I've sent them. If they still can't help, I'll flash it myself.
Thanks again for all your help ????

I thought I'd give T-Mobile support one more try... 3rd time lucky ? I reached some one who knows their stuff.
They pushed the update to my R805U a few minutes ago.
The update worked smoothly, busy applying the new Bixby update... Then I'll take a look around and checkout the new stuff.
However, I have no idea why the Wearable App would not get the update initially.
Thanks for the help. ??

Galaxy Watch 46mm LTE (SM-R805U) work in canada LTE (Region change)

HI ALL, I have samsung 46mm watch (SM-R805U) I think it is a USA version, I am trying to connect it to Canada LTE with Telus. I have the service to add a watch with my telus plan, but anytime I tried to connect through the wearable app i get the error that the mobile service for this watch not available in this region.
I did some searching, and I found that I can do the region change through SDB, I was able to successfully connect to the watch but I only get the USA providers options (XAR, ATT..) no other regions networks.
Is there anyway I could have this watch to work on the Canadian LTE, even by flashing the watch or other ways to change the region?

Try to look into other Thread/s)...
https://forum.xda-developers.com/smartwatch/galaxy-watch/samsung-galaxy-watch-geo-locked-t4035549
You are NOT alone.
Working solution:
Sell your US device
Buy Canadian Version...
Sorry, NO joke.
This is easiest solution without wasting time...
Only if your are good in GSM Hacking... Reversing stuff...
Feel free to deliver your own solution.
Good Luck.
Best Regards

There is away to change the firmware through Net-Odin, which could be able to unlock the region, but I am not sure what Firmware to use or where to download?

Again.
Feel free to find your own solution.
Maybe you are trying hard enough or by luck...
But IMHO I am not total idiot...
Sometimes.
You are not the first and will be not the last...

Edit 1
Info for you...
Here is SM-R805W this is IMHO Canadian Version...
https://easy-firmware.com/index.php?a=downloads&b=folder&id=36102
Here is US device Firmware for SM-R805U:
https://easy-firmware.com/index.php?a=downloads&b=folder&id=35613
From U like US IMHO somewehre free download... I can NOT remember for W like Cannada.
Simple Homework for you...
Unpack with Tool 7Zip the CSC...csc.img... then look with open eyes.
If you look correct, you will find Scripts for Preconfig...
These Files have nothing to do with the eSIM "Magic"...
IMHO the magic is minimum in CP part... Modem and/or on device...
I am from Germany.
I have not US nor Cannadian nor any European LTE Version...
So I can not do my own studies...
Nobody dump data...
Nobody log data...
Nobody share something...
Nor somebody do some Reversing Modem related...
For GWA2 some interesting files leaked... Modem related...
Good luck.
Please inform us if you have solution. :victory:
Edit 2.
I have only 1 Combination firmware... no Stock Firmware for research:

Code:

Maybe somebody find free SM-R805W or SM-R15W Firmware... for study...

This is great thank you for the help, I will give the firmware in the second edit a try, hopefully it does not brick the watch!!

NO. Not flash!
You will 10000% create problem... because you have SM-R805U
Please learn... try to read other posts ... threads.
Study... Research...
SM-R805U US USA NOT Cannada is here:
https://forum.xda-developers.com/smartwatch/galaxy-watch/firmware-r805u-t3936826
Maybe start with Lesson 1.
Download and unpack with 7Zip Tool.
Best Regards

thanks, I was able to update the firmware with the one in the link below. I did not have the UI update before but now it updates. Unfortunately the carrier list still did not change, I hope there is away I could change the region of the watch
https://forum.xda-developers.com/sma...r805u-t3936826

Meanwhile "we" have Stock Firmware for SM-R815W...
I could share...
Meanwhile I saw this:

Untested... NOT confirmed yet.

If anyone wants to try out the STOCK FIRMWARE, me and or adfree have a link to it.

Inside csc.img is exact 1 CSC /Sales Code...
Code:

Use 7Zip Tool to check content...
Maybe no need to change CSC via SDB... maybe auto select, because only 1 CSC inside...

Hey, so you never tried the firmware in the link? I actually have a 805W and I want to try flashing a different firmware to see if I can force an update. I'm on 4.0.0.0 on my 805W and can't get it to update to newer Tizen.

Hey adfree, I downloaded the 805W (I have this model) and extacted the tar, renamed the csc img to zip and extracted that (with some warnings).
Inside, there is a SW_Configuration.xml, but it only says
Code:
<CSCName>R805FAC</CSCName>
<CSCVersion>1ASA1</CSCVersion>
which is clearly not 805W. Is there another file I'm supposed to look at to see the actual CSC code?
Thanks

Samsung s20 Ultra Exynos ( Stuck on February 1st 2020 Update )

Hello everyone, this is my very first post here
I hope I posted this in the correct section of the forums. If not please point me out where I should place it! And sorry for the intrusion!
So basically my S20 Ultra ( Exynos variant SM-G988B/DS ) is stuck on February 1st, 2020 Update. My current version is G988BXXU1ATB3 /G988BOXM1ATB5 /G988BXXU1ATB2
I am pretty sure there have been tons of updates mainly to address the early camera issues, but I can't seem to make it visible to my current device so I can upgrade.
Is there a workaround in order to 'force' an update or I am missing something there?
Excuse my noobness
And nice to meet you all!

There are few threads crated on a daily that ask for the same. Just learn to flash it on your own via odin. No problem if you are noob... the problem if you don't use the search function and learn and move on from your noobness.
Download the firmware via SamFirm and flash it with odin. Stop waiting to receive OTA. Stay up to date, if you see there is a new update repeat those steps and you will always have the newest firmware.

This solution will not void your warranty. After you downloaded the firmware via SamFirm you will have in the extracted folder two kinds of a file that's called CSC. One of them is called HOME_CSC you need to flash/choose the HOME one in order to keep all your data.

I doesn't matter anymore, G988BOXM1ATB5 they put everything in one pot, OXM is generic. And you can't change that that easily or for free anymore.

Fantastic, thank you. So that means I can download whatever GSC I want and it should work perfectly with my phone?
trying to find out which is the best for my Exynos s20 Ultra but being a noob is very hard

SamFirm does it for you. Just enter G988B in the device slot and OXM for the CSC slot. It's going to show you the right/newest one.

Just an update, I successfully updated to the latest firmware using ODIN, I was nervous at first but the process is really straightforward. Still having focus problems with my s20 ultra tho, but that is a story for another
Thanks, everyone for guiding me to the right path!

Help for Changing CSC on Galaxy watch active 2 4g (German to french) I m french

Hello I need your help because I cannot use the 4g of my watch because of the German CSC while I live in France
SM-R825F
AP R825FXXU1ATD1
CP R825FXXU1ATD1
CSC R825FOXA1ATD1
HELP ME PLEASE

Look into this Thread:
https://forum.xda-developers.com/smartwatch/galaxy-watch/sm-r825f-csc-change-tutorial-t4061905
The good news for you...
You need only OXA Region files... IMHO allready posted...
DBT and XEF is inside OXA package...
Best Regards

Thank you
I have to start at step19 #?

Please remember I have NO Crystal Ball.
But I am little bit scared why you want start with SDB...
IMHO short summary...
A
netOdin Action to flash Combination firmware to have ROOT access
B
If still alive...
SDB Action...
SDB is similar to ADB from Android world...
C
netOdin Action again...
This time with Stock Firmware
Best Regards

OK do you have a link to download netodin for tizen please ?
Why are you afraid that I will start directly with SDB?
Best regards

netOdin:
https://forum.xda-developers.com/showpost.php?p=73503787&postcount=150
SDB Tool
https://forum.xda-developers.com/showpost.php?p=74585286&postcount=330
Best Regards

thank you very much but i don't know why but odin can't watch with the watch
I cannot validate the change of csc its put an error which says that the files and in lettering only in SDB command

Maybe you know my English skills are limited... and I still have NO Crystal Ball.
So i can not smell nor see what kind of Problems you see.
I only see 2 Tools inside 1 post.
I mean it is impossible to me. If step 1 is flash 1 file with netOdin...
Please if you expect any kind of help. Give FULL details what you see on your screen...
Best "magic" is Screenshot.
Best Regards

Example what I have expected...
It is possible to take this Combination Firmware now for SM-R825F and SM-R825U:
https://forum.xda-developers.com/showpost.php?p=82843303&postcount=61
Friendly user confirmed it work:
https://forum.xda-developers.com/showpost.php?p=82843789&postcount=62
This would be step 1...
Btw... few weeks ago I helped user from XEF to DBT with his SM-R825F... successfully.
So it is no Rocket Science. :angel:
Best Regards

hello I understood the procedure now and I found a video that explains well I have a problem with the COMBINATION-FT40_R825USQU1ASL2.tar which failed at the end so I rebooted with that the AP, BL, CSC R825FXXU1ASI7_Tizen no problem . So I don't understand why the COMBINATION-FT40_R825USQU1ASL2.tar failed

IMHO I wrote few times in the other Thread, why "failed"...
IGNORE Error, if Watch booting proper to Firmware...
Reason is additional file/folder...
Code:
meta-data/1.mf
Btw, this is why I have removed this... and posted...
Now you can proceed with SDB...
Please try to read Instructions... IMHO all hints given how to do...
Good Luck.
Best Regards

Okay so despite the failed and the watch that does not restart I restart the watch myself and proceed to change CSC via sbd.?
Best regards

Yes.
If nothing exploded and Watch boot into Tizen OS... so you can click around and find your IP address after connecting to WiFi...
Feel free to click around this thread... you are not the only one... not the first and maybe not the last... here for instance Screenshot of netOdin:
https://forum.xda-developers.com/showpost.php?p=82347797&postcount=32
IMHO only to need reading twice... or maybe more then 2 times or 3 or again.
Nearly all problems allready described in this thread... IMHO.

This TAR file is inside this 7Zip package:
Code:
ownRISK-FT40_R825USQU1ASL2_repair_v1.[B]7z[/B]
Differnce to the other files, I was toooo lazy to created the MD5 Hash,,,
So maybe better you use the allready known Combination Firmware... because MD5 is good for Selfcheck...
Hello I have a R825F
AP R825FXXU1ATD1
CP R825FXXU1ATD1
CSC R825FOXA1ATD1
and the combination file FT40_R825USQU1ASL2.tar does not work Netodin fail at the end and when I restart the watch an error message appears about the nfc and I cannot do anything except reboot on the stock firmware R825FXXU1ASI7 tizen 4 files and return after an OTA update on

Hi adfree ! Would that apply to me?
Excuse me for my English but I speak very little (which makes my understanding more difficult). I speak spanish.
Short version: I´m in Argentina with an Active 2 SM-825U (Tizen 5.5.0.2 / Build Number: R825USQU1CUD1 ) that cannot see the movil network.
Company says I should have bought SM-825 ( without U , my fault ) but confused me saying american models. After my bought said Mexico and Canada models )
My Questions:
1- What must I specific do ? Can I fix that only changing the CSC code to ARO , MXO or XAC ?
I not finding or not knowing what combination files I must use.
Don´t match last 4 characters: https://easy-firmware.com/index.php?a=downloads&b=folder&id=47818
2- I´d be interested to know if I can use SM-R820 or SM-R825 combination files or would that kill the watch ?
I´ve reached to establish communication between the watch and NetOdin but I´ve stopped there for not knowing the above.
From already, thank you very much ! Sincerely.... Eduardo.

anywhere to get r800xxu1dsl1 firmware downloaded?

so tried to change CSC.
downgrade to 4.0.0.4
got it up and running and CSC change.
But SPay doesnt work cause it says my watch was modified. Tried 3 times to load up the frimware and each time i got the same mofidication error.
trying to go back to 4.0.0.7 and i got the OTA but when trying to update, the watch says the update was not applied.
So now I need to do it manually, is there anywhere i can download r800xxu1dsl1 firmware? cant seem to find it anywhere ; <

posting for anyone that might have had the same issues as me...
i gave up... but i left my CSC at XAC from KOO when i downgraded to 4.0.0.4... the OTA update for 4.0.0.7 would not take.
I downloaded the file R800XXU1DTG1_Tizen_3File_CSC (OXA).zip from the link @adfree posted and flashed it using netOdin.
The upgrade worked... I left out the CSC file when upgarding to keep my XAC (not sure if that mattered).
I am now on 4.0.0.7, but now Samsung Pay works... WHOOT I had to restart my phone a few times cause when i initally opened SPay through the Gear Wearable app it said my country did not support SPay.
After the restart SPay updated (took 3 attempts) and now it's working ; >
now i need to get my watchface i designed back on there and SDB wont connect, but for now everything is good. Thanks @adree for your help!
