Here the help needed.

Step 19:-when you do sdb root on and then sdb shell. It will open a shell window on windows cmd. Here you can edit the required file.

When you type edit /csa/csc/csc-active-customer.inf in that window .It shoud open a file like

INU

~

~

~

~

and so on. Here INU is my country code india. If you want your watch to support samsung pay ,you need to change it to a country code where samsung pay is supported on Galaxy Wearble. So now you need to press the escape key on your keyboard. This will allow the editor to receive input option. Now when you press I on your keyboard.The editor will be switched to insert/edit mode. Now using arrow keys remove the existing country code e.g. 'INU' in my case. I changed it to XAR so it looked something like

XAR

~

~

~

~

Ensure there is no space after the word XAR (verify using arrow keys -->)

After this step press escape again to allow editor to receive input option.

Now type :wq!

this tells the editor to write override the file in Nand memry and quit the editor.

Ingore any error you receive here.

Step 20:-

On the same adb shell opened after :wq! type

edit /csa/imei/prodcode.dat

This will again open editor with prodcode file with contents something like below: where R820 is the model number in my case which is indian bluetooth only 44mm version (for lte version i think it is RM830 something) and the last 3 digits are INU for the country code. We need to similary edit the same file so that last 3 letters now correspond to XAR (one of the country code supporting samsung pay)

R820XXXXXINU

~

~

~

~

to someting like

R820XXXXXXAR

~

~

~

So again now you need to press the escape key on your keyboard. This will allow the editor to receive input option. Now when you press I on your keyboard.The editor will be switched to insert/edit mode. Now using arrow keys replcae last three digits of the existing country code e.g. 'INU' in my case. with XAR in the editor. So now something like R820XXXXXXAR. Again Ensure there is no space after the word XAR (verify using arrow keys -->)

After this step press escape again to allow editor to receive input option.

Now type :wq!

this tells the editor to write override the file in Nand memry and quit the editor.

Ingore any error you receive here.

21. reboot the device into recovery you now this

22. run netodin again and select AP, BL and CSC to flash stock firmware downloaded keeping the auto reboot option checked.

Hope It helps. Kudos to [MENTION=1030585]adfree[/MENTION] [MENTION=1017159]tb_[/MENTION] for amazing work . Tested to work fine on Indian Version 44mm Bluetooth only model RM-820 -Tizen 4.0.07 -R820XXU1BSJ6 firware. Let me know if any further clarification needed on any steps.

---------- Post added at 06:01 AM ---------- Previous post was at 05:54 AM ----------

Hi Tried it to change my Indian R820XXU1BSJ6 firmware watch to XAR code. Worked flawlessly.

Again it goes without saying Use at own risk brother. But you wanted to know if it works on this firmware. It does. these steps work.

Also, i was on tizen 4.0.0.7

Hello guys, i haven't understood a thing. This problem, is present also on glaxy watch? (i mean r810, galaxy watch of 42mm)

Because, here in italy, every update always comes after many months than every other country.. but, should i change my csc to XAR to make the update, i wouldn't be able to revert it to ITV?
[Samsung Galaxy Watch] goldiee36:
This is only for active2. You can change your watch CSC much easier with SDB, no need to flash it.

I bricked my Watch Active 2 44mm by flashing R830 firmware (40 mm). Stuck in odin mode. Could not go to wireless download mode. Took it to Samsung Repair Center. Warranty not covered. They charged me for 214 THB (~ 7 USD). They have to order a special cable to the repair center first. 1 day later, it is fixed. Just a correct firmware flash via usb cable fixed it.
[Samsung Galaxy Watch] erghetto:
Thanks for the answer, but i had understood that after the update, i can't revert CSC to ITV with previous guide, and that i will stuck in same situation of active 2.

Isn't it so?

Thanks I have tried the local Samsung service centre. Unfortunately I got my watch via a parallel import so they won’t touch it even if I pay. Any idea how to get one of those cables?
[Samsung Galaxy Watch] tolga9009:
I've gone through this rabbit hole on a GWA1, I don't recommend it. Atleast on my device, 4.0.0.7 breaks the SDB method aka csc-manager. It says launch successful, but the device doesn't show anything. So no, you wouldn't be able to go back to ITV.

In order to get back to DBT, I had to downgrade firmware to an older version (risky, sometimes even "guaranteed" brick, be careful), run csc-manager and update to latest version of my region again. Wasted a full day.

Watch won't update

So I've rooted a bunch of phones and tablets over the years but apparently I've gotten out of my depth on this process.

Ultimately I couldn't get sdb to connect with "failed" on both PC or laptop, so after a night of trying I decided to cut my losses and just used Odin to install the 820 stock files (have a 44mm stainless Bluetooth from Europe) figuring I'd be okay.

The main problem now: My watch won't take any updates, saying update failed each time I try. I've uninstalled and reinstalled the wear app. Rebooted the watch. Still nothing. Each time it goes through the motions of updating but says "couldn't update software. Try again later." Watch is otherwise normal.

There's also text over the splash screen that I can't seem to get rid of.

"Lot_id = NH3VK

SAVE TBL VER = 2

HW REV = 5

Ram = 768 MB GSO: 5 WIF:5 INT:5 CAW:5 CP:5

NAD : PASSED

APWB PROVISIONED"

Can anyone help?!!
[Samsung Galaxy Watch] Outofdepth:
Good news

Decided to start from scratch. Did two big things differently. First I used my laptop for all the Odin stuff. My PC kept failing and losing connection, which kept me from doing everything exactly correctly before (I had to add in several restarts)

The main SDB thing was to have the correct IP address. I think several people mistook the IP address in Odin as the IP address you need for SDB. They are completely different!!!! You have actually pull it up on settings in RobinGB's step 16. This is a really important step!!!!!

I found Robin's instructions easier to follow. Everything has worked out perfectly. The only thing I don't have is Samsung Pay (despite XAR CSC) but everything else has updated properly and the splash screen is normal again.

Update: Samsung pay just appeared!!!

I just literally opened my watch yesterday... it's from KOREA

GW 46mm

SM-R800

Tizen V 4.0.0.7

R800XXU1DSK2

I tried the old way to launch the config app but i guess with Tizen 4.0.0.7 they fixed that loop hole, cause after saying the config app launched successfully nothing happened on my watch..

Will this process work on on my GW?

the only part I am not clear on is what firmware to download for the watch...

EDIT: I found adfree's post in another threading regarding combination firmare for SM-R800

Combination Firmware

B

A AND B

Your Link is 50 %... A

My suggestion is downgrade Stock Firmware... IMHO part B...

Suggestion...

Please use Search ... somebody posted SM-R800 Stock Firmware... if i remember correct...

You NOT need Combination Firmware... so your Link is wrong or only 50 %... :D

Edit 1.

After some search on Youtube...

https://www.youtube.com/watch?v=bTFe5sZcLt8

After seeing this Video... here you can see also some red text...

My personal procedure since months/years is:

1.

First concentrate only on netOdin...

start netOdin... select all files you want flash...

2.

Only if netOdin finished MD5 check etc...

Only then I put my Watch into DL Mode...

If Watch tooo long in DL... then sometimes not more connect proper to Odin.... So correct timing...

No idea if GWA2 is faster... but Flashing takes about 20 + minutes for me...

I am NOT using Charger... to prevent heat and maybe other trouble...

My Watch is very close to my Notebook

I have NO Crystal Ball nor I can see what you can see...

All I know is... from older deviceS...

Your Photo shows IP and Mac... IMHO IP is only shown if PC detect Watch... so IMHO netOdin shows 192.128.40.20 too

Error message DL blabla

I saw this several times during my stupid tests... on my OLDer device SM-R760...

Next attempt with netOdin fixed this...

Still I have NO idea what you have treid to flash... nor where it failed...

Kernel and few other mandatory Firmware parts seems untouched valid... as DL Mode wireless only start if Linux Kerenl valid and alive...

Suggestions...

A

Check Odin screen... maybe something usefull visible...

Maybe RL or other Security crap prevent second attempt...

I mean option DL... looks like this...

https://xdaforums.com/showpost.php?p=80947411&postcount=9

B

Maybe try the other menu thingies... like recovery... maybe something need to be "clean" for second attempt...

From mom, friends or neighbar...

I succeeded. Suggest u follow posts #95 & #51's steps as the edits can be tricky. BTW, I got my R820 stainless steel Bluetooth GWA2 44mm from duty-free in Seoul airport, which had no Samsung Pay.

After I succeeded with these steps shown here, my GWA2 now has a working Samsung Pay. Also, mine was already on Tizen 4.0.0.7 before doing these steps. After flashing-editing-flashing, it went backwards to 4.0.06 (so, I didn't quite understand what was post #76 all about).

Then, upon pairing with my phone, the software got an update again to 4.0.0.7. No issues with Samsung Pay ever since.

---------- Post added at 10:19 AM ---------- Previous post was at 09:57 AM ----------

U may wish to try changing the CSC. My GWA2 was also bought in Korea without Samsung Pay. I live in Singapore, so I followed the steps here and changed the CSC' KOO to XSP and I am now able to use Samsung Pay.

Good luck.
