You can flash firmware R825F OXA,then you install TPK BP and ECG pusher.apk file from your phone (SamSung phone), your phone will push BP and ECG.tpk to your watch. You don't need change CSC to XAR (USA) beacuse USA didn't approve for BP, so BP is hidden on watch, next problem is you will receive error meta-data with firmware U (USA) version if you don't know how to remove meta-date file from firmware U version.

Hey, guys.

I'm interested in activating LTE feature in Gulf area (UAE).

There are no phone companies here which officially support the GWA2 LTE, but all of them are supporting Apple Watch, and one of them offers support for "Galaxy Watch LTE".

Is it somehow possible to "lie" to the carrier that GWA2 is a Galaxy Watch LTE or AppleWatch?

Thoughts? Which information are the keys of eSIM activation?
[Samsung Galaxy Watch] NETH_Andestal:
@Huy.tq I'm not sure you are still get deep into GAW2 CSC change, Can I ask something about this?

Since, I got the R825U from Amazon, but apparently, I'm struggle with using this one in KR.

I got this from FW ver R825USQ1ASI1. and tried to change CSC from XAR to KOO[Later on realized that there were no KOO for 825F version. and noticed that 825U and 825F looks different H/W type.

So, Basically I want to roll back to 825U with CSC XAR to get the extra supplement from Samsung official FW upgrade.

But, Before i realized the issue that i make, I've already changed CSC and here below is result.

AP : R825FXXU1ASJ4

CP : R825USQU1ASH3

CSC : R825FOKA1ASJ4

I already referred this post several times that it looks impossible to roll back to 825U without break knox.

Then, Is there any alternatives that i can get it?

Thanks for reply.
[Samsung Galaxy Watch] Huy.tq:
@NETH_Andestal,

Hi you, GROUP OKA (Korea) have 6 CSC

KTC

LUC

LUO

SKC

SKO

You should see here https://xdaforums.com/t/firmware-for-r825f.3997463/page-2#post-81683551

You can try change csc to LUO

If you want come back csc XAR you can flash fw U version but you reiceve error meta-data with flashing result is fail. You need unzip with 7z app and delete all meta-data file in fw, then you zip fw with file tar and then flash will pass

Good luck!
[Samsung Galaxy Watch] NETH_Andestal:
@Huy.tq

Thanks for reply. I can flash even though i got the error when i extract the FW files.

And also Does FW includes CP file ???

Since Even though i flashed, I can't get the FOTA. and also below is my GAW2 SW Version.

AP : R825USQU1ATF2

CP : R825USQU1ASH3 <-- doesn't changed since i didn't know that this also included to flash

Hi,

I've the same problem with my new smartwatch coming from Germany.

The only difference is that is R835F version instead of R825F version.

It is 40mm instead of 44mm so the question is, are some file to put on Odin the same or I have to find or download from Sammobile others?

Please let me know thanks. I wanted to use Lte and S Pay. With surprise I thought was possibile to recognize the Tim network here because of the same F bands but NO, it doesn't recognize it. So I'm very frustated and don't know if I can do something. I can't also sell it cause S Pay doesn't work also.

So please help me, what to use about which file to use on Odin.

Many thanks
[Samsung Galaxy Watch] sullivan2002:
Hi to all

I have a german R835F (40mm) and no LTE and S Pay work now in Italy.

Need to find a Stock firmware R835F to make it work and recognized by Tim Lte esim network here and S Pay with CSC Italian.

Who can give me the solution where to find the right files to use with Odin. Thanks in advance.
[Samsung Galaxy Watch] Huy.tq:
Hi you, I send you link download firmware R835F Brazil has LTE and SS Pay here: https://drive.google.com/folderview?id=1iPwyxZsCTQIrW1_e-DuVrThhxsi3gpUS
[Samsung Galaxy Watch] Huy.tq:
Firmware for nomal version (no LTE) have 3 file (BL, AP, CSC), different with nomal version, LTE version have 4 file (BL, AP, CP, CSC), CP is file for LTE. So you need flash once 4 file for LTE version
[Samsung Galaxy Watch] NETH_Andestal:
@Huy.tq

Really Appreciate your help to get it.

This would be the last question.

Do I start from flashing combination AP? or just proceed to "Recovery Mode" and Flash all 4 files[BL,AP,CP and CSC]?

Thanks for your help in adv.
[Samsung Galaxy Watch] Huy.tq:
Once with 4 file, no need flash combination file
[Samsung Galaxy Watch] sullivan2002:
Really Appreciate, I will try it tomorrow.

Many thanks.

If I could not solve, will be possibile to turn back or it will be no return?

Is Brasil version the same of Italy? The frequencies here are 800, 1800 and 2600 (B20 B3 B7).
[Samsung Galaxy Watch] Huy.tq:
Network frequency does not depend on the software but on the hardware of the clock. I transferred CSC from Vietnam to Korea and then Brizil with R835F version all works fine and currently 4G LTE. if US CSC then it will limit to 3G only

This link is fw R835F csc OXA (Euro Region), here https://drive.google.com/folderview?id=1lp17Tooqwr5iYUEzPFTSZ1q1q2TaRuQf
[Samsung Galaxy Watch] sullivan2002:
Ok so Tomorrow I will use the first gdrive link to download Brasil... and try to cook with Odin via Wireless and If it will not work or I want to turn back I will cook again with second gdrive OXA (Euro Region) files.

About S Pay, I hope these firmware changes will not diminish the security of S Pay

Thanks again for help.
[Samsung Galaxy Watch] NETH_Andestal:
@Huy.tq I flashed the ATF2 ver FW and now update FOTA to R825USQU1BTH9.

hi everyone. i have an active 2 sm-r825f german version, and i need to let it be italian..to do the procedure, it is necessary to use the oldest stock firmware (R825FXXU1ASI7) linked in the first post, or we can also use the latest one (R825FXXU1BTI9). in case you can use the latest one, can someone tell me where to find it? thanks
[Samsung Galaxy Watch] Huy.tq:
the language on the watch will be the same language on the phone connected to your watch, you just need to change the language on the phone and the watch language will change, this is always true for Watch periods are purchased or exchanged CCC to another country

[Samsung Galaxy Watch] Huy.tq:
You can flash 4 file BL, AP, CP, CSC once with fw R825FXXUBTI9, you will have CSC NEE (Sweden) and you have SS Pay with tizen 5.5.0.1
[Samsung Galaxy Watch] kledippi:
hi everyone, i have a question regarding the SM-R825F Watch. i live and ordered one in germany but it`s the AUT(Swiss) Version. Samsung pay is working in Switzerland but as i researched the forum, i think it`s not possible just to add a visa credit card (in my case a german one) which is supported internationally and in samsung pay (ch spay app version: VISA credit crad support) because i need a credit card and phone sim card from swiss to get registration completed? afaik i have also a problem when i want to use the LTE functionality (german telekom) with the swiss version of the watch? Both regions germany and swiss have the OXA Firmware so will it work when i purchase app over a german wifi network , will it download the german version then (ie. samsung pay germany) and will the LTE functionality work instantly with the AUT coded watch or do i have to change the csc to DBT first? But when i change only the region, will it work but root the device ( as i searched through the forum i think you need at first an old combination firmware that csc change work and so you need to flash a old version (ie 4.0.7) before and as a consequence i have rooted the device? But in Samsung Pay App and on website it's stated that it`s not working with rooted devices. so when i change i will still get problems with spay because its rooted then and maybe also with registration a german eSIM on the device because maybe one indicating counter inside the watch is set after flashing and indicate your provider eSIM, your samsung pay app or in general that your deviced was rooted once? furthermore is it possible at all to get LTE working, when your provider needs your eID/IMEA (which is a foreign one) to connect your watch with your eSIM profile ? pls help me with this problem, maybe there is a more simple way to get this all working in germany with the AUT coded device. thanks so much

Hi all!

So i got everything to work when i changed to Brazil.

However, i see that the Samsung Health Monitor doesnt update.

How do i update it?

I have downloaded the new SHM 175 from Caravana , and uninstalled the old one on the phone. ut i cannot uninstall the app on the watch.

The watch app is: 1.1.0029 and says the latest version is installled.

The phone: 1.1.0.175 Caravana

The reason i wanted to update is becase the ECG stopped working - it couldnt measure properly. BP works fine.

How do i get it to work again?

Im using a stock Samsung 10 and a R835F 40mm
[Samsung Galaxy Watch] sullivan2002:
I have the same Active 2 R835F 40mm and same smartphone Samsung S10. Tomorrow I will try to put Brasil Firmware as suggested by Huy.tq

in order to make it work with LTE, S Pay and ECG EPP.

I want to ask, do you think that LTE on and Bluetooth off WiFi off, will consume a lot of Battery?

Another ask, if I put WiFi on connected to my smartphone, can I receive notifications?
[Samsung Galaxy Watch] Huy.tq:
If you turn off bluetooth, turn off wifi but use LTE, it may use more battery power if you use bluetooth connected via phone, in addition if you connect via LTE and turn on remote connection with phone, you will only receive Notifications, but not direct calls
[Samsung Galaxy Watch] Huy.tq:
To update SHM on the clock from .29 to .31, you need to perform the following steps:

1. Remove the sim card from the phone

2. Turn on VPN to Brazil (using Hotspot shield VPN software or any VPN application)

3. On phone: Go to settings -> apps -> Galaxy Store -> Clear data

4. Exit -> launch galaxy store app -> go to app update -> you will see SHM app with new version -> update to install

One thing is that ECG works well on tizen 5.5.0.1 and with .29 version. If your watch cannot be used, you can check the ECG sensor error by going to the call on the watch, pressing * # 0 * # will display the TESTMODE -> press 11 times in a row on the word TESTMODE, then scrolling down it will show the word 2TEST -> click on 2TEST (put the watch on hand and put the index finger of the non-watch's hand on the back key, like you are measuring real ECG -> wait about 5 seconds it will The result is 0, the sensor works well, if the position is 5 the sensor is broken, to be sure, you need to check many times.

@Huy.tq Appreciate your help to find out the firmware through EF. but i fails with EF Extraction like below picture.

File Name : R825FXXU1ATA1_Tizen_4File_Multi CSC (OXA).ef

Download link - Download - MEGA

Does it reflect the OKA Flashing? for using KTC[Korea Telecom Company] is it okay to use above mentioned FW ?

Problem itself is that I've converted and at the last flashed R825FXXU1ASJ4_Tizen with CSC -KTC.

But I can't get the OTA. Can you advise how to solve it?
[Samsung Galaxy Watch] loni90:
Hi!

Thanks alot for the detailed info.

So, best is not to update to .31 but to stay on .29?

When ilI try ECG the needle spikes up and down like crazy and cannot measure my ECG.

I will try to go to Testmode and see what it says.

Thank you
[Samsung Galaxy Watch] loni90:
Here are my results of the 2TEST and also how my ECG spikes. No matter how i hold it, it spikes like that.
[Samsung Galaxy Watch] Huy.tq:
group csc OXA of euro zone not OKA of Korea, so CSC KTC will not update OTA with fw OXA

You can try fw this with tizen 5.5.0.1 herehttps://androidfilehost.com/?fid=10763459528675591247
[Samsung Galaxy Watch] Huy.tq:
actually I had an ECG problem just like you on my R820 (I tried it on my R835F and R825F and the ECG worked fine), just yesterday I brought an SS service center in my area to test the ECG sensor but they said the sensor was working fine and had another flash fw for me even though my LO result was also zero but measuring the ECG wave is very large but no beat heart and usually ends at the 25th second, I have tried installing the older SHM version .23 and had one successful but the signal was poor, but after this time I failed to take the ECG test all the rest . It's really sad but I don't know what to do, even though I've tried it a few dozen times:(:(
[Samsung Galaxy Watch] Huy.tq:
After I tried the SHM .23, .29, .31 versions the SHM .29 version gave good ECG results, although I had to experiment with moving the index finger positions on the ECG sensor, the attempts The initial test was also disappointing, but after a few successful attempts the waves were less vibrating and showed a more stable heart-wave chart.
[Samsung Galaxy Watch] traysh:
Hi,

I followed the instructions and changed my SM-R825F region to Brazil (I think). After updating some times, my watch now has Samsung Health Monitor installed and, when I opened it for the first time, it also installed in my Galaxy S10. But now, when I run it on my phone, I get a pop up "Service is not available - Samsung Health Monitor is not available in your current location".

I bought both my phone and my and my watch in Sweden, but I am currently in Brazil, using a local SIM card. How can I fix this problem?

edit: the software version reported by the watch is R825FXXU1BTJ1 SM-R825FSKAZZTO
[Samsung Galaxy Watch] Huy.tq:
You can delete SHM on your phone and install SHM 175 mod 4 posted by Caravana here for fix that error https://drive.google.com/file/d/17WU3eZpyOUIOcWstEWSVvGTYO-18Bg6Q/view?usp=drivesdk
[Samsung Galaxy Watch] traysh:
Thanks!

Unfortunately, before I read your answer, I flashed the ZTO firmware again. Everything seemed ok, but I can't update my watch anymore, so I'm stuck in version 4.0.0.6. When I try to update, I get an error "Couldn't update software - try again later". Also, there is a text in the boot splash, see bellow.

I don't mind much the text on the boot splash, but can you help me with the update problem, please?
[Samsung Galaxy Watch] Huy.tq:
You can flash once 3 file BL, AP, CSC but untick auto reboot on odin, then you flash file CP and reboot your watch

This error has also happened to a few people during the flashing process that may have had a Bootloader (BL) error which resulted in an error when updating the tizen version as well as the blue screen on rebooting.
[Samsung Galaxy Watch] Huy.tq:
we may not need to change csc to get BP and ECG feature updates. Because initially only Korea and Brazil received the new tizen version 5.5 and updated BP and ECG (USA only ECG), it was necessary to change the CSC to Korea or Brazil. The conditions for BP to work are tizen 4.0.0.7 and active ECG is tizen 4.0.0.8 and Samsung phones from android 7 and above. But now as far as I know that all countries have tizen update 5.5.0.1 so if you don't have BP and ECG in the update then you just need to install the latest Pusher BPandECG .31 is pulled from watch by @adfree and installed on your watch in combination with Caravana's SHM 175 mod 4 file, then you can use BP and ECG. This is the simplest way to get BP and ECG working without flash, avoiding the risk of errors. You should only change csc when you want to active SS Pay.

As you said I didn't need to flash ZTO anymore, I did what you said and flashed the R825FXXU1ASI7_OXA firmware - first BL, AP and CSC and then CP. Everything went well, but I still cannot update, same error =(

Any other ideas?

When you flash U version will receive error meta-data, with combination file is not important problem, because you need root permission. But with file Stock firmware U version for flash success you can extract file and delete meta-data file, then zip them with tar file
[Samsung Galaxy Watch] Danylo1996:
ATF2 I can't flash as I had 5.5 tizen before...

How to delete meta-data from there? Can you help me with that?
[Samsung Galaxy Watch] Huy.tq:
Not important tizen version, it will not error so tizen version. If you want to delete meta-data, you can unzip tar file with 7zip software and delete any meta-data file in them, then you zip them with 7zip and format tar

[Samsung Galaxy Watch] Huy.tq:
No, you should flash once 4 file BL, AP, CP, CSC of fw R825XXU1BTI9, you will have tizen 5.5.0.1
[Samsung Galaxy Watch] Huy.tq:
You can flash once 4 file BL, AP, CP, CSC fw R825UOYN1ATF2. Or you can flash once 4 file BL, AP, CP, CSC fw R825FXXU1BTI9, then your watch will change from U version to F version and your watch have SS Pay of NEE (Sweden), you can install BP and ECG from file pusher.

[Samsung Galaxy Watch] Danylo1996:
But these 4 file BL, AP, CP, CSC work only for usual firmware. For combination doesn't work... Is there way to flash and how I can change region?
[Samsung Galaxy Watch] Danylo1996:
Hello everyone, is there a way to change the region to SM-R825U?

I tried:

1) Roll back to 4.0.6 and then flash the combination - eternal loading.

2) a combination with other files (BL, AP, CP, CSC)

The result is always the same - forever loading after firmware

P.S. I have already successfully changed the region to R820 twice, so I understand the algorithm ...
[Samsung Galaxy Watch] Huy.tq:
I've shown you how to do it that you seem to be ignoring or not understanding. You only need to flash 4 files of BL, AP, CP, CSC once, you will be able to complete any U or F version firmware, for U version you have to delete the meta-data file to flash successfully, no need to use. combination file if flashed in this way. If the OXA version you will have a CSC of NEE, If the U version you will have CSC XAR
[Samsung Galaxy Watch] Danylo1996:
Sorry, maybe I really didn't understand something before. But I don't need CSC of NEE or XAR, I need SEK(Ukraine). Is there way to do CSC SEK(Ukraine)?
