You can do tutorial with process 30 steps to change csc to SEK or any CSC (but not csc SEK for LTE version, only CSC SEK for normal version)

Check notify update csc SEK (error reported) https://doc.samsungmobile.com/SM-R825F/SEK/doc.html

Or NEE (Sweden) https://doc.samsungmobile.com/SM-R825F/NEE/doc.html

Or DBT (Germany) https://doc.samsungmobile.com/SM-R825F/DBT/doc.html

Or XAR (US) https://doc.samsungmobile.com/SM-R825U/XAR/doc.html

You can flash to change csc with fw R825XXU1BTI9 OXA https://androidfilehost.com/?fid=10763459528675591247. It will change U version to F version

Hi,

I made it with Brasil Firmware for my Active 2 R835F, Thanks to

Huy.tq

Now I have Samsung Pay, unfortunately, I cannot put the esim cause my Company gives this error: THERE ARE NO TARIFF PROFILES FOR YOUR WATCH, although is the only one here in Italy that has esim possibility for a smartwatch. I don't know how to do to associate it. I have the relative sim inside my S10 Samsung Smartphone from where I have installed the app Galaxy Wearable

Maybe I have to go to the Phone Company Shop and pass a sim or buy a new sim phone esim and after that I could find a Tariff Profile on the App showed, (could you confirm this please?)

Another ask, where I can find ECG? Do I have to download or pay for a specific app to show this?

Thanks a lot
[Samsung Galaxy Watch] Huy.tq:
@sullivan2002 file for install ECG and BP here
[Samsung Galaxy Watch] sullivan2002:
Now seem to work

Many thanks for Help
[Samsung Galaxy Watch] sullivan2002:
Today I made the calibration with an Arm sphygmomanometer for the blood pressure monitor

here video:

Calibration Test

It seems to work quite well then for the battery it is not that you have to use it many times a day but maybe once.

About ECG I saw the first measurement went well, then I did other measurements and It went crazy, now I don't know what it is due to.
[Samsung Galaxy Watch] sullivan2002:
Fantastic, very next to the sphygmomanometer measurement

ECG now works well
[Samsung Galaxy Watch] Danylo1996:
Now I got it. And I picked ZTO. Thank you very much

@Huy.tq

I'm sorry for being a nag but I'm not sure I fully understand my options... :)

My situation - got an Active 2 that was correctly registered with LTE (

someone else, different phone number different rate plan

) and then CSC changed to NEE to support Samsung Pay. I paired it with my Samsung Note 10+ but of course LTE would not find correct rate plan since the CSC was not matching.

I don't know exactly what firmware was installed but I believe some oldish one. I just ran the steps from the guide in this thread so got it to COMBINATION-FT40_R825USQU1ASL2, changed CSC, flashed the R825FXXU1ASI7 and then it started to work. Also got the offered OTA update to R825FXXU1ATA1 since otherwise LTE was not fully registering.

I'm now being offered to OTA update to R825FXXU1BTI9 which I avoided so I can check my options because I'd like to be able to get the Samsung Pay available once again.

My understanding is I need a COMBINATION type of firmware to get root access so I can change the CSC to NEE. My best guess is to go once again through COMBINATION-FT40_R825USQU1ASL2 so I can do that and then flash with R825FXXU1BTI9 NetOdin. Hopefully the LTE profile is kept (at least that's what everyone else confirmed so far and that's what happened with this specific watch on the last try with the same service provider I'm using). BUT if anything gets messed up for any reason, once I get to R825FXXU1BTI9 so Tizen 5.5.0.1 I'd need a COMBINATION-FT55..... something otherwise I'm breaking the watch, right?? :D If so, is there any link to download such?

- I saw you said several times that the only thing needed is to flash the 4 files in the R825FXXU1BTI9 package but I don't get how that would change my CSC (currently ROM) to NEE :)

- thank you for providing links to the BP and ECG, they're working now on my current firmware :)
[Samsung Galaxy Watch] sullivan2002:
Now I have Samsung Pay, ECG, EPP but I cannot use LTE. Always on scan Phone Company profiles gives me that no profiles found for my Active2 but I'm sure the Company has profiles for Galaxy Watch3 so must be the same. I think problem is the same. Maybe I need the Italian CSC for this and is not possibile with Brasil Firmware.
[Samsung Galaxy Watch] adfree:
IMHO config of eSIM crap only possible in CORRECT Firmware... CSC...

Then you can jump between foreign CSC/Region... because eSIM Settings/Profile not erased...

Best Regards
[Samsung Galaxy Watch] primusmagestri:
your best bet is to fix the CSC, everywhere I've looked, that's the solution everyone used. Now I'm not sure it's the only one, I tried to get my service provider to add the rate plan manually and see the pic below, they managed to add something but was missing the EID. I kept asking if maybe they would need the EID, the guy kept saying no no no :) I figured it's not gonna work so I said I'll get back to them if I still have issues. After changing the CSC back to ROM it kicked off and finally another rate plan added as you can see below. I could have insisted they add that EID there and check if it works but i didn't want to risk them finding out I've messed with it and cancel the warranty.

I saw several people stating they didn't lose the profile. My watch didn't on the original attempt, hopefully that would be the same when I attempt it.
[Samsung Galaxy Watch] sullivan2002:
About the warranty, at this time, I don't worry. I don't care about it but I don't know if I could change again its firmware in order to keep this LTE function. Now I have ECG EPP and SPay, I don't know also if I will change firmware, I will loose these I have now. LTE function is the hardware that I payed more and this is the reason that I will try to make it work also on my smartwatch.

If there is another firmware that makes all these function work will be welcome, alternatively just LTE and SPay

it would take an Android App independent from Samsung's Wear in order to scan a QR code of another operator who has Esim to send it to the watch
[Samsung Galaxy Watch] primusmagestri:
for BP and ECG you have the option here explained by Huy.tq https://xdaforums.com/t/sm-r825f-csc-change-tutorial.4061905/page-16#post-84156473

it worked for me but I agree on an older firmware so I've yet to test how it would look on the latest one.

regarding LTE, you might try to convince your service provider to create that rate plan and add all the options. I'm not sure there's any fancy provisioning kicked off from the watch or it's the same if the service provider makes all the necessary settings in the backend. You've got nothing to lose :)
[Samsung Galaxy Watch] primusmagestri:
So having an official like firmware running, R825FXXU1ATA1 i did this

1. Write R825FXXU1ATA1 over the existing firmware, was R825FXXU1ATA1 already, LTE profile was kept

2. Wanting spay samsung pay i went over the entire flow of write old combination firmware, write back some new firmware. Wrote R825FXXU1ATA1 not sure hie important. I got the LTE profile and Samsung Pay 😆

SHM sideloaded as Huy.tq explained

now should i update to latest firmware R825FXXU1BTI9 ? I can do it with Netodin or even OTA, I'm being offered that

Is there any way back from there to this startover process? And would i get Tizen 5.5.0.1 also with the Netodin option? I guess so.
[Samsung Galaxy Watch] sullivan2002:
Hi,

How is possibile to convince my service provider to do that?

Returning to my problem:

1. I have now R835FXXU1BTJ1 software version (Brasil one)

2. I have BP and ECG work fine

3. I Have SPay work fine (ok SPay points goes to Brasil :( but Not interested on)

I need to make LTE works on my Active R835F

Now here in Italy there is a Phone Company that sell the Samsung Watch3 not the Active2. I fon't know if its the reason for not finding tariff profiles on scan

But

Maybe need to change CSC to ITV to may work

Maybe I will loose BP and ECG but there are maybe other way to unlock them

Is it another firmware now to test on my 835F (active2 41mm) in order to see if I could find LTE profiles?

Another ask, If I buy a sim card (for the samsung smartphone) from Brasil can I bypass the issue? In order to transfer the Italian profile to the smartwatch?
[Samsung Galaxy Watch] primusmagestri:
Convince your service provider meaning ask them do manually set what the watch + phone would accomplish. Showed above, my provider sales support guys were kind enough to add the rate plan but the whole deal wasn't going through, i suppose because they haven't set the EID besides rest of details.

The watch ain't doing any magic, just asjs the phone which in turn asks the service provider systems to associate the phone number with one additional SIM, in case of GWA2 and other LTE watches, an eSIM. Not too far from a SIM clone 😁 The functionality ought to be in the backoffice UIs as well for manual fixes, correctikns etc. So my guess is you only need a friendly support guy to do that.

If that don't work, as i said, best bet to get back to the ITV CSC. But don't rush with that, as far as i've read downgrading Tizen messes up the watch so you get stuck with a semi-bricked watch.

Regarding the other Q: Getting a Brasil SIM would not help at all IMHO, what should that do?...
[Samsung Galaxy Watch] sullivan2002:
I tried on my Samsung smartphone to put different sim card.

Look at pictures attached.

Every time I change sim card on my smartphone connected via bluetooth to my Active2, I went on Wear App and scanned for Tariff profiles. As you see it depend on the phone company to decide if it's a conpatible watch in order to unlock the QR Code scan of another esim that I know could work on my Active2 but I'm stopped to scan the QR Code just by the Company phone of the Sim card that I use inside my S10 Samsung Smartphone. I tried Italian Tim, Russian Tele2 and UK sim and all the three sim, didn't permit to scan, reason they don't have profiles for my watch, SO If I have a brasilian "Vivo" or "Claro" sim inside and I have brasil firmware on the watch, maybe they recognize that they have the tariff profile for my watch and the QR Code scan could start scanning another italian phone Company sim, that I know from other forums that could work, these also if I use Brasil Sim in roaming here I suppose. Brasil cause I have Brasil Firmware, German in case somebody has german Firmware...
[Samsung Galaxy Watch] primusmagestri:
But your ultimate goal would be to have a rate plan for the service provider you're using and paired with the phone you're using, not some random Brasil number.

The GWA2 i have has been used by my brother coincidentally on the same service provider i use, Orange. After i got the watch, paired with my phone, LTE still available on the watch - ON HIS PHONE NUMBER 😄

Well, when he finally deactivated the rate plan for the watch, i started getting the option to look for LTE plans for my phone number, same results as above.

Yes, probably a Brasil SIM would work, hopefully would not mind that it's roaming. But that would get your watch to use a Brasil phone number, is that what you're looking for?

I myself have switched from S3 Frontier to GWA2 LTE in order to have same phone number on my wastch as on my phone and be able to go out biking, running and still be reachable on my same phone number.
[Samsung Galaxy Watch] sullivan2002:
"Yes, probably a Brasil SIM would work, what you're looking for?"

No, I'm not looking to use a brasilian phone but only just to transfer the QR Code of another italian ESIM Card that others made with Samsung Galaxy Watch 3 and for sure goes also with Active2. The brasilian sim card on roaming here must be just a tool to let me open the QR Code scanner. And after I will put away the brasilian sim card.
[Samsung Galaxy Watch] primusmagestri:
Interesting endeavor, hope you manage to get a SIM like that and try that option :)

But in my case there was no QR scanning, it just went on and created the relevant service in my rate plan and hooked it with the eSIM of the watch. Granted, different country, different provider so your experience may be different.
[Samsung Galaxy Watch] sullivan2002:
But I don't know if would be easier put again german firmware or europe OXA and buy the german sim instead of brasil one that could be difficult.

Or maybe Romanian one. I know that Orange Ro could work
[Samsung Galaxy Watch] sullivan2002:
Where I can find to download the R835F ITV Italian CSC Firmware?

Maybe I can try to put it and for BP and ECG I do a different way

Thanks
[Samsung Galaxy Watch] primusmagestri:
You'll probably need a combination firmware again to allow to change the CSC but MAKE SURE you use a recent version otherwise you'll brick the watch. There are several threads from several people describing that.

I saw there are some Tizen 5 combi firmware on EasyFirmware , I'm waiting for someone to make one available around here.

Yes, Orange RO works, that's my service provider and i have the LTE working on my phone.
[Samsung Galaxy Watch] sullivan2002:
it is better to have the latest TIZEN software version right?

I have version 5.5.0.1
[Samsung Galaxy Watch] primusmagestri:
in general, probably yes. newer operating system, newer software, newer everything gives you best options, right? like latest firmware combo plus the brasil ZTO CSC gave you the BP and ESG

but all i meant was, don't downgrade it now trying to fiddle with the CSC because it seems it doesn't work https://xdaforums.com/t/how-to-connect-samsung-galaxy-watch-active-2-to-your-pc-via-usb.4214173/
[Samsung Galaxy Watch] sullivan2002:
But I don't know still now if I have to put the specific ITV version or just the OXA version

Now that I have Brasil Firmware,

could I flash with netodin just only the CSC? and not to cook the other 3 files?

CSC_OXA_R835FOXA1ATA1_usr.tar.md5

another thing what is it for SDB Tool?:

I live in sweden (csc NEE), is it possible to change csc to the US one to get the latest update and then change back to NEE while still remaining on the latest update?
[Samsung Galaxy Watch] primusmagestri:
What firmware version are you on?
[Samsung Galaxy Watch] primusmagestri:
i accepted the update to BTI9 and the ECG Is finally working, previously was stopping after 5 sec.

i'll be stuck with NEE CSC and this firmware until someone offers the combination firmware and most importantly confirms it works 😀

The first update to tizen 5. I still haven't got the update that includes voice coach and improved gps-accuracy.
[Samsung Galaxy Watch] primusmagestri:
frankly, I'd like those as well but I'm not sure simply flashing that firmware gets you the XAR CSC automatically so if you'd need to first change the CSC using a combination firmware, don't use that old one which has Tizen 4, a lot of people bricked their watches this way...

Whats the newest firmware for the R835F?
[Samsung Galaxy Watch] MadRat0815:
Hi.

I am pretty new in this topic, but maybe you can answer my questions pretty easy.

My Setup:

Galaxy Watch Active 2 (LTE) 7807

Type: SM-R825F

Tizen 5.5.01

Smartphone

Galaxy S20 Pro+

Everything was bought and will be used in Germany.

I bought the Active watch esp.because ot the ECG and other Health Features. By the way, they are still not available in Germany.

What I did for now....

I watched following video to understand how to change the country settings on the watch

Youtube Video

I downloaded following tools

-SDB_2.2.60 (WIN64bit)

-WiFi_Net_Odin

Now it goes to the Firmware Files.

I dont know wich Files I shall download and use...

I downloaded follwing files but as I said, I am a bit scared if they are old ore the wrong ones...

-COMBINATION-FT40_R825USQU1ASL2.tar

-AP_R825FXXU1ASI7_usr.tar

-BL_R825FXXU1ASI7_usr.tar

-CP_R825FXXU1ASI7_CL1263214_QB13943174_SIGNED.tar

-CSC_GCFTEST_R825FGCFTEST1ASI7_usr.tar

-CSC_OXA_R825FOXA1ASI7_usr.tar

Can you tell me if those files are the right ones for my Setup?

I would like to change the watch from germany to US (it seems that this is the version with all of my needed features).

If these Files are the right ones, I would like to do the procedure like explained on page one (here in this topic).

Thanks a lot.
[Samsung Galaxy Watch] MadRat0815:
EDIT: I opened a new Thread about my request. My question is a bit away from this topic. Sorry Guys.

My Thread

HI and good morning guys.

I tried to do the procedure, explained in post 1 here in this thread, but Netodin says after arround 10min "Fail".

Then I loose the Wifi Connection and the Watch in still in the Download Modus.

What did I to solve the problem?

-Reboot the watch, to start again the Wifi-AP Mode. This works pretty fine and I can use Netodin again. But... again the message fail (after starting the netodin process again)

THants for now....

I thought its not so difficult to follow the instructions and get the Health features available on a german watch.

But it isnt (seems so).

My qestion to you know is...

How can I get the old Stock SW 5.5.01 DBT Version running like it was before I tried to change CSC?

It would be pretty nice and helpfull, If you can tell me how and where I can get the right SW for my watch.

Thanks a thousand times.

I've just faced with the same issue.

Solution: downgrading tizen from 5.5.0.1 to 4.x.x.x

So, just apply Step#28 before howto in heading post.
[Samsung Galaxy Watch] sullivan2002:
Now I have all ok, ok not just all :

LTE ok, EPP ok, ECG ok, SPay ok :) remain SPo2 NO :confused:, but hope it will be ok in the next future on my Samsung Galaxy Active 2

Now that I have my ESIM on the watch working, I stopped Bluetooth and stopped WiFI for battery consumption.

I have to do some duration tests, if it does not last long, I disable LTE and enable it only when needed.

Now the question is, is there a way to get notifications (I'm only interested in Whatsapp at the moment) from the primary number that's on the smartphone that I wouldn't take with me?

Better would be a Whatsapp Lite APP to be installed on the Active 2 but I think that the phone one is then disabled so what to do?

ps: when the warranty will end, I think to open the battery slot and change it with a better battery.

I don't know if someone made this before. I want to find a bigger capacity to put on it.

After this mod, this Watch will be the Best and more complete, and Beautiful Watch ever seen.

Samsung Watch 3 is heavier, bigger, Cannot put silicone transparent cover due to the physical bezel.

I have to thank this forum and friends that give me the right help and courage to do this! (y):love:
[Samsung Galaxy Watch] sullivan2002:
Now I'm searching for a simple APP to install on my Active 2 that switches from LTE to Bluetooth, I mean, when I have my smartphone Samsung with me I quickly switch on Bluetooth and when I go outside to run or walk,I enable LTE with call transfer from my smartphone number and at the same time it has to automatically disconnect the Bluetooth and wifi as soon as I enable LTE, does anyone know if there is a simple App?

I know I can go to the settings every time but there are too many maneuvers to be done, I would like it to be enough to press a button, for example, I think of an App where it shows on the screen some colored buttons that are pressed to enable and disable or just a button only one that enables LTE or pressing it Bluetooth and WiFi or just Bluetooth.

now that I remember, maybe there is an option to customize a button, maybe I can do it this way

the double press of the HOME BUTTON to customize but I looked there is no LTE on and off for example
[Samsung Galaxy Watch] sullivan2002:
Hi,

Need to know about a strange thing:

I started from yesterday to use LTE instead of Bluetooth. So I put Bluetooth Off and WiFi Off. But I don't understand why notifications comes (WhatsApp ecc...) from my Samsung smartphone that is not connected via Bluetooth to the Active 2. It's good I like it but I don't know the reason. How it could receive them if works just a different esim number on LTE but no connections to the phone
[Samsung Galaxy Watch] Koe77:
I have purchased a German GWA2 LTE, just like you and I have the same problem, I can't seem to find a right sim to get the esim qr to be read! How did you solve it?
[Samsung Galaxy Watch] Koe77:
There's an app called macrodroid (it works like tasker but easier to set up) with which you can create an automatism that whenever your phone looses the BT connection to the GWA2 transfer any call to the esim. There are many guides on the internet explaining how to do it. Hope it helps!
[Samsung Galaxy Watch] sullivan2002:
I found the solution here, But of course you have to get an esim at your name active.
[Samsung Galaxy Watch] sullivan2002:
for the phone call transfers, I don't have problems, very easy I put *21*phone number of WA2# and every calls come to me to my watch when I go outside to run or walk or in the summer to swim.

When I want to put off the call transfer code #21#.

The problem are notifications of Whatsapp but as I wrote in my previous post, seems to come although is not connected by Bluetooth to my Whatsapp Smartphone.

Now I was searching for a VERY SIMPLE APP FOR ACTIVE 2 (if someone knows please let me know thanks) that PUT ON LTE and OFF at the same time WiFi and Bluetooth or VICE VERSA

In this way, I don't have to Settings and again to find Connections and again to find Bluetooth and put off. Ok, there is a button named AIR MODE but this button put off Bluetooth and LTE and WiFi in the same time and it's not what I need.
[Samsung Galaxy Watch] djtd23:
Hello, New member here looking for an assist on this very useful post. I've a WA2 LTE originally SM-R835U. I successfully flashed the combination firmware (COMBINATION-FT40_R835USQU1ASK4.tar.md5) via Netodin3, ran the sdb commands to update CSC, then flashed the four firmware files (AP_R835FXXU1ASI5_usr.tar.md5, BL_R835FXXU1ATF5_usr.tar.md5, CP_R835FXXU1ATF5_CL1263214_QB16133250_SIGNED.tar.md5, and CSC_OXA_R835FOXA1ATA1_usr.tar.md5)

Was very happy with it until I realized I put in the wrong CSC (ITV instead of carrier-specific).

Started process again, flashed same combination firmware,

Ran sdb commands to correct CSC

Then when flashing the four firmwares my computer disconnected from the watch and reconnected to my wifi.

It gave me the fail in netodin and "download error detected"

Now the combination firmware boots fine, I can connect in AP mode but get this failure from netodin when I try and flash the firmware.
