Update firmware with NetOdin

Hi all,
I noticed that the BSA4 update has been released everywhere except Australia. I've been able to get my hands on the firmware files but do not know how to get the watch to connect with NetOdin.
Has anyone been able to do this? I've seen videos of it for the Gear S2 and Gear S3 but there is no way to "restart" the device, only "power off".
Any help would be greatly appreciated.
cheers,
Hieu.

Actually nevermind I managed to get it working on my own..

Nice going!

so where you get firmware....and how did you do it...give us a rundown

Hi, have you succeeded? Can you give us a tutorial so that everyone can enjoy it?

Sure guys. Will put something together later today after work. Getting my hands on the firmware took a bit of searching but managed to find it on a Russian forum.
Will provide a run down of the process and links to the firmware (note: only know where to download the firmware for the 46mm and 42mm Bluetooth version, not the LTE).

0. This process will factory reset your Watch, so make sure you've backed up everything you need!
1. Hold down the Home button for 6-10 seconds until the message " Rebooting ... "
2. Quickly press Home three times until the Reboot Menu appears. (The menu is available for about 10 seconds, after which the clock goes back to "Rebooting ...")
3. The menu selection is made by long holding Home button. To go into Download (wireless mode) press the home button until "Download (Wireless)" is highlighted, then hold down the Home button.
4. Download mode will load in WPS mode. Press Home twice to change the mode to the AP.
5. Connect to the access point that appears (for example, SM-R800-a2a5) (ODIN for some reason does not see the device if several networks are connected.)
6. Run NetOdin3 and then set the firmware files for BL, AP and CSC, then click Start (Copying/flashing of firmware takes about 20 minutes).
7. After the files are downloaded, the Watch will reboot. Again, hold Home and highlight & select Recovery in the Reboot menu.
8. The "Setting Up" screen and "Resetting" screen should appear and after that the Watch will reboot and boot as usual.
N.B. It is advisable to check whether you have disabled the function "find my watch" or make sure you remember the password to your Samsung Account
Files can be found here for R800 and R810 (46mm and 42mm Bluetooth / Non-LTE G.Watches) and NetOdin3 for Tizen:

Restart both devices and try again is what I'd recommend. And disconnect from your home wifi that you're usually connected to on your PC first before trying to connect to your Watch's access point.

It says that 5 seconds after being connected to network, via WPS or AP it's the same... 5 seconds ? Too slow ?...

I've deleted all data about my home wifi in my computer, and it's the same problem, and if i connect via wps, it is exactly the same, any developper option to activate before ? like Android devices ?

Here is netOdin since Gear S2.. S3...

Nothing. You don't need to activate anything in developer menu. Have you tried on another computer?
My connection is always stable on AP connection mode.

Don't have another computer, that's why i've tested via WPS
Will test later to fectory reset, maybe an internal bug

easy way to fix Samsung pay on non Samsung devices

enable magisk hide on those apps in screenshot. Use xmlpak magisk mod if you don't see Samsung in play store after activating it on your watch

Please edit title to state that is requires a rooted phone, a simple "[ROOT]" would be fine. Don't want to have a misleading title.

I'm running a rooted note 9 and latest magisk, yet I don't see any of those apps in magisk hide? Not sure why

I have a Samsung galaxy watch 42mm and Nokia 7 Plus, i live in India, since i got the watch there is no option of Samsung pay in Galaxy wear app. I manually installed latest Samsung pay plugin ( https://www.apkmirror.com/apk/samsu...n/samsung-pay-watch-plug-in-1-7-5906-release/ ) , and changed the region to Australia and after that when i paired the watch again with galaxy wear app Samsung pay is showing in it, and i then followed the instructions in the app to set it up.
I followed the below instructions samsung pay works on my nokia 7 plus.
You do NOT need root.
But this is how you do it.
1. So first, download SDBstarterKidv1 from the following link please:
https://forum.xda-developers.com/showpost.php?p=74585286&postcount=330
WARNING: This will reset your watch, so make sure you back it up so you can restore it later.
2. Next make sure your watch is set up as follows:
- Debugging Mode turned ON
- Connect watch to WiFi and get its IP address (To find the IP address on Galaxy Watch: Settings > Connections > Wifi > Wifi Networks > [your network] > Scroll down to IP address)
3. Next, from SDBstarterKidv1 double click on 'install.bat' (it will not install, it just flashes a window, but this step is required)
4. From the subfolder data\tools double click on 'sdb.exe' (it will not install, it just flashes a window, but this step is required too)
After noting IP address of the Galaxy Watch, Launch ‘Ansicon.exe’ from sdb_2.2.60_windows-64\data\tools (this thing will open a command prompt window, and all the action is done here)
5. Type: sdb connect [IP of Galaxy Watch]
6. Look at Galaxy Watch, it will prompt you to accept a message
7. If you try the sdb connect [IP address] again, it will say "already connected". This means we are connected and good to continue.
8. Type: sdb shell and Enter
9. Copy Paste: launch_app csc-manager.csc-pre-configuration and Enter
So this lets you change the region of the watch. Now for me I changed mine to Austrailia. The code for Austrailia is XSA
Once the watch is reset, pair it back up with your phone.
10. Once pared with your phone you will need to:
- Turn on developer mode again
- Turn on debugging mode
- Turn off the watch and turn it back on again.
- You may need to wait a few minutes.
11. Once you have done this, you can open the Samsung Galaxy Wearable app and go to settings. When you scroll down you should see samsung pay.
If you dont see pay, hold down the back button (Top right button) on the watch till samsung pay opens up and follow the instuctions to set it up. But initially the Samsung pay app is not recognising my compatible Indian Debit and Credit card and not allowing me to add, i thought this might be that i had changed the region to Australia, but i tried again after an hour and then to my surprise i am able to add all my 4 cards to Samsung pay app , and it is working also, i tried a payment at NFC enabled terminal and payment works flawlessly
Enjoy your new watch with Samsung Pay enabled.

I followed your steps, but chose SEK as region (thinking it was Sweden). However, now it's impossible to connect to the watch again with sdb. When trying to connect, I sometimes get responses like ¥¸ºeÇþx or other strange characters
EDIT: After the reset when I changed the region, the watch was also showing cyrillic characters for the instructions. However, as soon as I connected my phone, the watch changed to english.
EDIT2: I installed Tizen Studio to get the most recent version of SDB. And after a reboot of the watch, it looks like I'm getting closer:

To delete the key, and after restarting the watch again and running sdb kill-server, I was able to connect again and get the request to confirm my computer.
Damn Samsung, why is this **** so buggy?

Hey,
Is it possible that thanks to your method I will be able to turn on Samsung pay in my country (Poland) if it is not supported? Only Google pay works. Maybe I will need to do it using paypal? Thank you for your help in advance

Fixed by using an older version of the plugin

FYI, I just received my Galaxy Watch today. Installed Samsung Pay (ver. 1.9.1206) on my Pixel 3XL and tried to run it but was denied because of Magisk (ver. 19.3 stable). So I hid the Manager via Hide Magisk Manager from within the app. I then was allowed to go through the setup process and add a credit card.

Failed to connect with remote device.
I have getting error failed to connect with remote device while connecting to galaxy watch . How to fix this.

Hello guys,
I also have error - failed to connect. When I try to ping the watch, the ping responses...
I tried it on fresh Windows 7 and 10 installations, also on Mac. Also tried to add the port to IP address. But always failed to connect... There is no message on the watch.
Any idea guys?
Thanks a lot.

What was your reasoning for doing this? To get updates faster? To be able to use LTE in a different area? Both?

So all you did was flash the canadian firmware on your watch and LTE worked in canada? Just wanting to make sure 100% that this works cause i dont want a bricked watch You flashed over wifi netodin then clicked mobile networks and found the watch?

My watch is 825F, before was DBT now became ITV with OXA firmware.
I flashed combination firmware for 825U like tutorial, made CSC change and then flashed stock firmware OXA.
When I flashed combination fw net odin gived me an error, but I continued to flash CSC, in my case worked at 100%.
Only now I read that you have 815U, therefore I don't know if this tutorial works for your model!
Bedt regards

I see step #28 launch net odin connect your watch ad charge your stock firmware (Step#3) and press start. Do you mean load BL, AP and CP then flash? or add CSC too? Sorry that step is confusing to me.

Just out of curiosity, if something goes wrong, what would i do to go back to the way the watch was before? Just flash the original firmware and reboot? Thx

If something goes wrong you could brick your watch or could be lock wifi mode in odin like this link
https://forum.xda-developers.com/sm...axy-watch-active-2-44mm-sm-r820-odin-t4009587

Well thats what happened just right now Luckily i have the usb mod cable. So i guess ill just load up the original firmware and flash it back.
Mind you, adfree said i could probable get away with just flashing the stock firmware for my watch since its a regular galaxy 42mm watch. Let's just say he was wrong. So ill try your method now and see how it goes. At least i know i can get back to stock and try again with the Gear S charger.

I suggest to you to see this post where someone talk about canadian firmware
https://forum.xda-developers.com/smartwatch/galaxy-watch/changing-cs-gwa2-sm-r825f-t4017839/page4

Tried it your way too and a garbled screen came up but then pressed power to get to recovery menu (after flashing .csc) then held power but now im stuck in odin mode again (till i usb it again) then start from scratch It doesnt seem to want to go into recovery mode after flashing combined and csc.
---------- Post added at 07:30 PM ---------- Previous post was at 06:43 PM ----------

Well, I've tried every method known so far and at the end I get the odin screen which i need to recover from using the Gear S charger. This method or the russian youtube method will not work for the regular galaxy watches (42 and 44mm) I've been trying for 10 hours with no luck. Anyone else want to give it a go? I've even tried leaving the auto reboot in odin checked and i still only get to the "go to the recovery menu then hold power" till it reboots to recovery on the watch. That's where my luck ends. I get the odin screen which needs the Gear S charget to get back to 815U. Make sure you use the U combination firmware (if youre coming from the AT&T watch)

I used for my SM-R825F this file COMBINATION FT40 R825FSQU1ASL2 from easy firmware that they give for SM-R825F in fact the download is COMBINATION FT40 R825FSQU1ASL2 but really, when download is finished the name of file is COMBINATION FT40 R825USQU1ASL2 and all worked fine for me!

K i just got a membership there too and downloaded the latest combination and regular firmware for the galaxy watch 42mm SM-R815U. Let's see if it works now!

Suggest to you to flash only your BL with jtag and then if works try to flash all firmware with net odin

Do you mean the last step where i flash all 4, flash BL with jtag then connect wireless with the reset?

In a video of youtube, at first flash BL with jtag, then flash alla firmware (BL AP C0 CSC) with netodin in wifi mode.

If i flash BL with jtag, i have to reboot into wireless download mode and the watch hangs at odin causing me to restart the whole process. BTW, while flashing any of the files here, it says "OK" and nothing was skipped over on the write process.
So just to 100% confirm, when flashing the CSC file, are you using the one from the oringinal firmware or the new one you want to install? Also do you have matching firmware files and combination files? (same letters and numbers in the file name)?

Samsung JUST released Firmware Update R825USQU1ATF2 for the Galaxy Watch Active2 (SM-R825U) on 7/24/20, so it would appear that you do have the latest.
The Sprint Change Log appears to be the same as ATT & TMobile: https://doc.samsungmobile.com/SM-R825U/SPR/doc.html
We have two SM-R825U's, one with an LTE Data connection, one without (BlueTooth/WiFi Only).
The update was completed on 7/28/20 on the one with the LTE Data connection.
However, I have yet to see the update on the WiFi Only watch... and I've manually checked every day... at least once
Not sure what it takes to actually get an Update on a Samsung Watch FROM Samsung It appears that you need to have an LTE Connection with a Cellular Provide r

wow, in Europe, the SM-R825F is on 4.0.0.7 since February.
Why on USA it has been recently updated only to 4.0.0.6? Can't understand...
And Bluetooth versions are receiving 4.0.0.8...
Meanwhile, new watch3 is on 5.5.0.1.. I really hope later this year Samsung bring Tizen 5.5 to the rest of Galaxy watches, at least to the Active2.

Do anybody have R825USQU1BTH9? I have a problem due flash combine firmware because I had tizen 5.5 I guess...

[SM-R800][4.0.0.7]CSC Change Process

So I recently got a Samsung Galaxy Watch (SM-R800), but to my dismay, Samsung Pay was not available in it by default.
By searching on xda, I found out that running some simple sdb commands would do it, but unfortunately, it worked only in 4.0.0.4 version and mine had 4.0.0.7 out of the box.
Then I found out that the watch can be easily downgraded 4.0.0.4 and then perform the sdb shell commands, setup Samsung pay and upgrade to latest version again. Although finding the process was easy, finding the required firmware files took a lot of time, going through the threads and all. But I found them eventually.
To make it easier to come back to and to help wandering souls if any, I decided to create this thread.
Although I have written for SM-R800 specifically, it may work on other watches too as the firmware link has firmware for other watches too(R810,R805F,R815F,R805U,R815U).
Download links:
NetOdin3_1.0.zip
SDBstarterKidv1.zip
SDBstarterKidv1.zip
Firmware's can be found here : https://4pda.ru/forum/index.php?showtopic=978373&st=80#entry92121314
Following is the process I followed:
Charge watch, at least 90% . This is required as your watch will reboot many times during the process.
Set screen timeout to 5 minutes
Backup your data if any. This process resets watch multiple times.
Keep the WiFi password simple/open, you have to enter it multiple times in the watch during process.
Download
a. Old firmware
b. New Firmware
c. NetOdin3_1.0.zip
d. SDBstarterKidv1.zip
Reboot watch to Download (wireless). To do this:
a. Press and hold power button
b. When you see rebooting on screen, press power button a few times
c. You will get a menu like below
d. By pressing power button, highlight ‘Download (wireless)’ mode and then press power button long to select it
This puts the watch in WPS mode, but we need AP mode in this case. To switch to AP mode, press power button twice, you will see image as below:
Now on laptop/PC, connect to an open WiFi which has name of the device. In My case it was SM-R800.
After connecting, watch will continuously show “Connection timed out error 110”. This is fine.
Now open NetOdin3.exe as administrator. After sometime, the NetOdin window will show IP address of the watch and <ID:0/001> 192.168.49.1 in the Log window. If it is not connecting, try disabling firewall (or Windows defender).
Now once the watch is connected, select the appropriate files in three boxes. For me it was:
a. BL : BL_R800XXU1CSI1_usr.tar.md5
b. AP : AP_R800XXU1CSI1_usr.tar.md5
c. CSC : CSC_OXA_R800OXA1CSI1_usr.tar.md5
Just make sure watch is still connected (IP address is shown in Odin software)
Press Start button. After about 10 minutes, flashing process completes. During my process, it had failed once on by showing on the Odin software. All I did was reboot the watch in same way in Download(Wireless) mode and do the process again.
Complete the setup on watch.
Connect the watch to WiFi, even if doesn’t have internet it is okay. Note down the IP address(Settings>Connections>Wifi>Wifi Networks><connected_network>IP address).
Enable debugging on the watch(Settings> About Watch> Debugging).
REBOOT THE WATCH. Debugging doesn’t connect without it.
Now setup sdb to access your laptop.
a. Extract SDBstarterKidv1.zip
b. Extract zip inside it as per your Laptop/PC OS.
c. Run install.bat/install.sh as per OS.
d. Then go inside data/tools and run ansicon.exe as administrator. It will launch a command prompt window.
e. In it type sdb connect watch_ip_address
f. It will show connected.
I would recommend taking backup of your current CSC info. To do so type following two command in sdb:
a. sdb pull /csa/csc/csc-active-customer.inf
b. sdb pull /csa/imei/prodcode.dat
This will copy those two files in you current directory. The 3 ending letters are your current CSC code.
Now to change CSC, type following in your command prompt window:
a. sdb shell
b. You will get something like sh-3.2$ for prompt.
c. Then type: launch_app csc-manager.csc-pre-configuration
d. It will show “... successfully launched”
e. Now look on your watch, switch to CSC you want to . I selected XAR which is for US and at top of the list.
f. Touch on XAR and then it will reset your watch.
Now check if you have the Samsung pay app in the watch. If not there, You need to open the Galaxy Wearable app in the phone after pairing with watch.
In it, you will find the Samsung Pay option. Click on it, you will be asked to download the Samsung Pay plugin. Install from play store if available in your country or download it from apkmirror. If your phone is rooted, before starting the plugin app after installing it, hide root from the app in Magisk hide or something equivalent.
One thing to note over here is I had used US VPN to connect and setup over phone now, so if it doesn’t work in normally way, try using VPN. I used the TurboVPN, it has free servers too.
Do the setup on phone as well as watch by entering the card details.
At this point, the watch has Samsung pay, but it is still on the old firmware. And unfortunately, update operation from Galaxy Wearable app doesn’t show an update available. So, we need to again flash the latest firmware using Odin.
Repeat steps from step 5 till step 13.
Since the watch will be reset, the Samsung pay icon from watch goes away again, but it is available in the Galaxy Wearable app. Open it, sign in it. If card details were already added, they can be imported back from Samsung account.
Done!
Multiple times during the flashing process, either my WiFi disconnected from laptop or it failed due to some reason, but I was able to always reboot the watch in Download mode again.
I have some screenshots/images too, I will upload them soon.

Thank you @Mirhawk.
One of the best & most detailed explaination.

Does it matter which region firmware you download or are they the same? I Have SM-R810. Also, do you need to have Samsung Pay in the phone?

Thank you for a great explanation. I was stuck on R800XXU1CSD6 and finaly was able to upgrade to R800XXU1DSL1.
My R800 did not get any OTA after I change csc code to get Pay working.
Samsung Pay still works after this upgrade

"9. After connecting, watch will continuously show “Connection timed out error 110”. This is fine"
Anyway after my laptop was connected to SM-R800 i changed network settings (changed network for "public") and this error went off from my watch. Of course I switched off antivirus and windows firewall at the beginning.
After all I had the same problem when was installing last process of this instruction (new version). At first time i had fail but second time worked (maybe low signal from laptop or something dont know)

Which firmaweres do i need to download for SM-R810 with 4.0.0.7 ? I need to downgrade for chance CSC tu UK for samsung pay. I have SM-R810 with the DSL1 firmware right now.

does anyone know, why update no longer works after changing csc?

Just wanted to write here that it worked for me here in AUS, brought a SM-R800 grey import. Just follow the above directs to the T. lol just wanted to add that "e. In it type sdb connect watch_ip_address" watch_ip_address is your watches IP! rooky error. lol. also booting into AP mode I found tricky too but using odin and the cmd command the easy part! thanks again

It works perfectly. The key is to know what firmware do you need.

So I recently got a Samsung Galaxy Watch (SM-R800), but to my dismay, Samsung Pay was not available in it by default.
By searching on xda, I found out that running some simple sdb commands would do it, but unfortunately, it worked only in 4.0.0.4 version and mine had 4.0.0.7 out of the box.
Then I found out that the watch can be easily downgraded 4.0.0.4 and then perform the sdb shell commands, setup Samsung pay and upgrade to latest version again. Although finding the process was easy, finding the required firmware files took a lot of time, going through the threads and all. But I found them eventually.
To make it easier to come back to and to help wandering souls if any, I decided to create this thread.
Although I have written for SM-R800 specifically, it may work on other watches too as the firmware link has firmware for other watches too(R810,R805F,R815F,R805U,R815U).
Download links:
NetOdin3_1.0.zip
SDBstarterKidv1.zip
SDBstarterKidv1.zip
Firmware's can be found here : https://4pda.ru/forum/index.php?showtopic=978373&st=80#entry92121314
Following is the process I followed:
Charge watch, at least 90% . This is required as your watch will reboot many times during the process.
Set screen timeout to 5 minutes
Backup your data if any. This process resets watch multiple times.
Keep the WiFi password simple/open, you have to enter it multiple times in the watch during process.
Download
a. Old firmware
b. New Firmware
c. NetOdin3_1.0.zip
d. SDBstarterKidv1.zip
Reboot watch to Download (wireless). To do this:
a. Press and hold power button
b. When you see rebooting on screen, press power button a few times
c. You will get a menu like below
d. By pressing power button, highlight ‘Download (wireless)’ mode and then press power button long to select it
This puts the watch in WPS mode, but we need AP mode in this case. To switch to AP mode, press power button twice, you will see image as below:
Now on laptop/PC, connect to an open WiFi which has name of the device. In My case it was SM-R800.
After connecting, watch will continuously show “Connection timed out error 110”. This is fine.
Now open NetOdin3.exe as administrator. After sometime, the NetOdin window will show IP address of the watch and <ID:0/001> 192.168.49.1 in the Log window. If it is not connecting, try disabling firewall (or Windows defender).
Now once the watch is connected, select the appropriate files in three boxes. For me it was:
a. BL : BL_R800XXU1CSI1_usr.tar.md5
b. AP : AP_R800XXU1CSI1_usr.tar.md5
c. CSC : CSC_OXA_R800OXA1CSI1_usr.tar.md5
Just make sure watch is still connected (IP address is shown in Odin software)
Press Start button. After about 10 minutes, flashing process completes. During my process, it had failed once on by showing on the Odin software. All I did was reboot the watch in same way in Download(Wireless) mode and do the process again.
Complete the setup on watch.
Connect the watch to WiFi, even if doesn’t have internet it is okay. Note down the IP address(Settings>Connections>Wifi>Wifi Networks><connected_network>IP address).
Enable debugging on the watch(Settings> About Watch> Debugging).
REBOOT THE WATCH. Debugging doesn’t connect without it.
Now setup sdb to access your laptop.
a. Extract SDBstarterKidv1.zip
b. Extract zip inside it as per your Laptop/PC OS.
c. Run install.bat/install.sh as per OS.
d. Then go inside data/tools and run ansicon.exe as administrator. It will launch a command prompt window.
e. In it type sdb connect watch_ip_address
f. It will show connected.
I would recommend taking backup of your current CSC info. To do so type following two command in sdb:
a. sdb pull /csa/csc/csc-active-customer.inf
b. sdb pull /csa/imei/prodcode.dat
This will copy those two files in you current directory. The 3 ending letters are your current CSC code.
Now to change CSC, type following in your command prompt window:
a. sdb shell
b. You will get something like sh-3.2$ for prompt.
c. Then type: launch_app csc-manager.csc-pre-configuration
d. It will show “... successfully launched”
e. Now look on your watch, switch to CSC you want to . I selected XAR which is for US and at top of the list.
f. Touch on XAR and then it will reset your watch.
Now check if you have the Samsung pay app in the watch. If not there, You need to open the Galaxy Wearable app in the phone after pairing with watch.
In it, you will find the Samsung Pay option. Click on it, you will be asked to download the Samsung Pay plugin. Install from play store if available in your country or download it from apkmirror. If your phone is rooted, before starting the plugin app after installing it, hide root from the app in Magisk hide or something equivalent.
One thing to note over here is I had used US VPN to connect and setup over phone now, so if it doesn’t work in normally way, try using VPN. I used the TurboVPN, it has free servers too.
Do the setup on phone as well as watch by entering the card details.
At this point, the watch has Samsung pay, but it is still on the old firmware. And unfortunately, update operation from Galaxy Wearable app doesn’t show an update available. So, we need to again flash the latest firmware using Odin.
Repeat steps from step 5 till step 13.
Since the watch will be reset, the Samsung pay icon from watch goes away again, but it is available in the Galaxy Wearable app. Open it, sign in it. If card details were already added, they can be imported back from Samsung account.
Done!
Multiple times during the flashing process, either my WiFi disconnected from laptop or it failed due to some reason, but I was able to always reboot the watch in Download mode again.
I have some screenshots/images too, I will upload them soon.
