Hi!
I've been lurking this forum for a while and am really eager to change my Galaxy Watch Active 2 CSC from Hungary to UK to make Samsung Pay work. I have a Curve card specially for this but I've been too afraid to do it because I'm afraid I will lose the 4G functionality of my Hungarian Telekom provider.
Right now my watch is set up with Telekom and has 4G set up as esim.
My big question is if I change my CSC to UK, will I lose the 4G functionality? Will I still be able to connect to my Hungarian esim account?
Please let me know, any information is greatly appreciated!!

I did it, Samsung Pay worked, but it doesn't connect to the Telekom network. Then I also made the mistake of wanting to re-register the eSIM, but it no longer allows me to try any available ROM. Now I should get the factory Telekom ROM, but I have no idea where it comes from. It sucks. Very big sucks.
Theory.
ESIM is activated and work. :good:
IMHO eSIM profile will not be erased.
So IMHO eSIM is lowest problem.
But SPay chance 50 / 50...
Maybe your plan will NOT work for Samsung Pay...

Hi Adfree,
First of all I want to thank you for your reply and all the work you are doing for this community. You are by far THE Galaxy watch expert. You're always commenting constructive feedback to people.
Everywhere I see your comments and helping out people. A big THANK YOU!
I will try to change the CSC, even though I'm a big newbie to this.
One last question: will I be able to revert the watch to its original state if it turns out it doesn't work? With that I mean original firmware that it came with?

To increase your chance to get Original Status... my suggestion:
A
Check Firmware infos on your device to be 99,9 % sure what you need...
Type like you would call someone:
Code:
*#1234#
Then you see all relevant infos to find your Firmware...
B
For Orignal Settings... my suggestion with SDB Tool from here:
https://forum.xda-developers.com/showpost.php?p=74585286&postcount=330
B.1
Check Bootloader Version sboot.bin
Code:
cat /proc/cmdline
B.2
Check active CSC
Code:
cat /csa/csc/csc-active-customer.inf
B.3
Check Product Code
Code:
cat /csa/imei/prodcode.dat
You can save these infos with Screenshot or by Copy and Paste Text only... with right Mouse Button.

Hi,
I was wondering if there is any way to extract the firmware from my S8500T handset? I'm wanting to do this as there is no copy of this firmware available and I want it as a back-up in case things go wrong with flashing to other firmwares.
my S8500T runs S8500MBJF2, S8500HUTJF2
any ideas?
thanks!
What country / provider is your phone?
@ beigebullet
Please post Product Code you see this via sTune. Something like this : GT-S8500BAADBT
So I could try something...
About your Question.
Not impossible, but only JTAG known to dump Firmware.

Ah do you mean 'Product Name'? In sTune all I get is xxxxxxxxxxxx.
I've manually changed my CSC from HUT (ie. Three Hutchison australia) to KOR but I can change that back if needed...
I've uploaded a pic of what it shows me

Yes, correct.
xxxxxxxx I saw several times.
This means NV item 2757 (HEX Value) is empty.
Kies without valid Product Code do nothing.

P.S:
S8500T
Attention!
I'm not sure. But for instance S8500R seems to have problems with normal Firmware... maybe incompatibility.

Hmm, so can I somehow get a valid Product Code from Samsung?
And yes, the S8500T is not compatible with normal firmware, as the T version runs on 850/2100Mhz bands, not the 900/2100 on standard firmware. This is the reason I want to extract the firmware from my phone, as I'd like it for a backup.
Thanks for your help adfree
Hello I just bought Galaxy watch and I believe it was manufactured in Saudi arabia. I'm missing some apps such as spotify and galaxy app of my phone is in arabic and I can't seem to change that.
Is there a way for me to switch the region of my watch to something like USA so that I could install Spotify. and I know this isn't related but how do I change the region on Galaxy Wearable ? when I acess galaxy apps from it everything is in arabic which is really annoying.
Thank you !
Are you able to identify your exact Watch Model Name?
Example...
SM-R800 or SM-R810 or SM-R815F or...
Best Regards
Model: SM-R800
Serial No : R5AKA0NGARA
Tizen version: 4.0.0.1
Software version R800XXU1BRJ4
and it's the 46mm version
I hope that's helpfull
You can change to XAR, this is the CSC/Sales Code for USA...
With Tool SDB...

This is not temporary... this is static...
To Reset to "default" you have to know your CSC/Sales Code... and go the same way to choose it...
So I suggest first... identify your active CSC...
Code:
launch_app csc-manager.csc-[B]verifier[/B]
Then NEXT step to change...
Best Regards
Thank you so much. Last couple of questions. excuse my noob tech skills :silly:
but will this void my warranty ( as far as I understand I can switch back csc to what it was and they won't notice I changed that). and will I still get future updates or is this process is similar to rooting on android phones
again.. I'm noob at this
excuse my noob tech skills

NO problem.
Please remember thes tiny hints...
A
I am User... not Samsung Seller nor in any other kind married with Samsung...
B
What ever you see CSC/Sales Code related... is "against" Samsung policy/rules crap...
Otherwise they would give you official instruction.
C
CSC/Sales Code aka region lock/crap Branding Warranty Tales...
Serial Number detects Original Factory CSC...
This is why they ask you about Serial Number...
D
OWN RISK
What ever I say/write...
and if you fail...
You can never say... but adfree told...
Please choose wisely...
Or ask Samsung and/or your Seller...

Some dude, did you need to change your Samsung account region to the United States as well?
Hi There: Is this procedure still possible - I`m from Germany and we over here can`t use Samsung pay - will it be possible to use S pay after changing the region ???
AND what will happen with the sim card - will it still be in Germany - silly question...
How can I know which region my watch is set on? I'm from Mexico and I can not use samsung pay, the model of my watch is SM-R800. regards
Only as hint...

hi all
couldn't find information about this using google or searching here.
Useful stuff i've found:
wiki. tizen .org/Porting_Guide/Tizen_Bootup_Overview (no information about signing or checksums) [remove whitespaces]
I was wondering:
1. Can I simply flash anything via Odin and it will still boot or is there some signing going on? maybe just some "custom" packing?
2. Has any1 built tizen "from scratch" using their repos (?
3. Are there more information about the bootloader(s)? do they use u-boot? (saw that in their git repo)
Thanks a lot in advance!

WEAR OS
if it was done on the gear s, why isn't it possible to do with the galaxy watch or any others for that matter? I would rather have Wear OS instead of Tizen because of the universal capability to use on multiple platforms, plus the convenience of a plethora of apps. Samsung doesn't have versatility, or so it seems...
Is there anyone who has successfully rooted anything after the S2 and uses Wear?

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

HELP ME PLEASE
Look into this Thread:

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:

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.

Example what I have expected...
It is possible to take this Combination Firmware now for SM-R825F and SM-R825U:

Friendly user confirmed it work:

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:

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:

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.
Hello guys,
I have seen a lot of topics on this subject and honestly i don`t know were to start. Yes, i am a old guy and total noob on flashing roms and so on...
Recently my carrier in RO, Vodafone has implemented an option that allows using ESIM on other devices. that being said i proceed activation the option and trying to make my trusty companion R815F to work. Went to Samsung care and they told me that the watch is using an UK region code and will not work with my RO carrier. ( bought the watch also in Romania but .. well apparently it was destinate for other country code)
My watch :
Model number: SM-R815F
Serial: RFAN31FSY2E
SW version: R815FXXU1HVG1 SM-R815FZKABTU
Tizen version: 5.5.0.2
What have i done till now:
- developer mode on
-debug mode on
-download ODIN
-download SDK
-connected to watch via CMD
-tried launch_app csc-manager.csc-pre-configuration - getting an error " internal/external comand ... etc"
Now, being a total noob i don`t understand the next steps:
- do i need combination file and firmware rom for changing the region ?
- do i need to downgrade to tizen 4 in order to do something ? ( how to ?)
- where to find stock firmware - which one to choose because i found something that is paid and i don't want to waste money on something that is not working
Please if anybody can help me or give me a hint were to start it will be much appreciated.
Thank you,
A
Code:
COMBINATION-FT40_R815FXXU1ATA1.tar.md5
Risk because untested...
ATA1 could be dangerous outdated...
No idea from where to download this file... for free...
I will do some search...

Thanks for the feedback. i will wait for your findings.
Hi,
Sorry for being so impatient But did you find something?
Thank you,
A
Sorry.
I have nearly nothing on my HDDs... only really old files.
My suggestion for you.
Search for Firmware Files in Internet...
You can post here what you found. BEFORE you try,,,
For instance start with this file:
Code:
COMBINATION-FT40_R815FXXU1ATA1.tar.md5
Sorry I have my own problems and limited time and energy...
So you at your own...
Good Luck.
Best Regards
You searched for SM-R815 - CombinationFirmware.com
combinationfirmware.com
Here seems only older...
You searched for SM-R815 - Samsung Combination File
samsungcombinationfile.com
Here seems no F...
Found via Google...
I finally made it work thank to user: Jon199102 on Reddit.
He point me to a "hidden feature" of Galaxy Wearables - hidden menu to activate QR code searching/integrating -> auto or manually set up the ESIM. after enabling it i scan my qr code from VDF Ro and 10 minutes later everything was working
I don't really know if it is allowed to post the link to Reddit but here it goes :
