Update firmware with NetOdin


Jul 6, 2011
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:

Hi everyone.

I recently bought a Galaxy Watch running Tizen out of the box, and I wanted to use Samsung Pay with it.

So, I tried changing the region (CSC) using the sdb method mentioned above. Unfortunately, I've then read and verified it doesn't work on

Then I tried using NetOdin to downgrade my firmware, as suggested above, but the connection times out after 20 seconds and I fear the flash will be incomplete and I could brick my watch. I don't believe the firewall would be a problem because NetOdin does recognize the device for 20 seconds before timing out.

I also read something about tapping into the access pins on the back and connecting a cable, but I'd rather not mess around with the watch's internals.

Any ideas on how to fix the timeout, or another method I could use to change the CSC?

Your time and attention are much appreciated. :)

EDIT: It kept timing-out, until it simply started working. The one time it didn't time out, I couldn't believe it. Rebooted just to make sure, and it kept on working. Had to update the system back to Tizen through Odin, though (the Galaxy Wear app wasn't finding the update). Thanks for your attention. :)

Hello I have the Galaxy Watch SM-800 Bluetooth only version, according to Samsung there is an update. But Galaxy Wearble does not show any. I have the version R800XXU1DSL1, I don't know if there are different CSC versions like my Note 10 Plus, my Note 10 Plus has the German DBT version on it. My question is how do I get the correct version or the latest update on my smartwatch?

Hi guys,

I have the SM-R500 and I was trying to update the firmware using NetOdin, I could solve it, first with the AP installation.

Then I was able to turn on the device, all good...but then on the step to connect my smartwatch to the wireless (to change the region), and the smartwatch don't find any wireless network...

Then I was trying to do a new installation using NetOdin and when I'm facing the download (wireless screen) I'm facing the attach file error..."wd_cm_setup_ap: Failed to run soft AP -1"

Can anyone have a clue to solve one of the two situations?

Thank you so much in advance.

Salut les gars,

J'ai le SM-R500 et j'essayais de mettre à jour le firmware en utilisant NetOdin, je pourrais le résoudre, d'abord avec l'installation AP.

Ensuite, j'ai pu allumer l'appareil, tout va bien ... mais ensuite sur l'étape pour connecter ma smartwatch au sans fil (pour changer de région), et la smartwatch ne trouve aucun réseau sans fil ...

Ensuite, j'essayais de faire une nouvelle installation à l'aide de NetOdin et lorsque je suis face au téléchargement (écran sans fil), je suis confronté à l'erreur de fichier joint ... "wd_cm_setup_ap: Impossible d'exécuter le logiciel AP -1"

Quelqu'un peut-il avoir un indice pour résoudre l'une des deux situations?

Merci d'avance.
Même problème avec affichage de "l’impossibilité d’exécuter le logiciel AP-1"après avoir essayé un firmware trouvé ici qui a désactivé le wifi.
Tu peux vérifier, car ma watch active 2 ne peux même plus se connecter en wifi car ne trouve plus le réseau.
