How to claim warranty for Samsung Gear Watch? topic

I have contacted Samsung online and voice support for several times.
I am told that the serial number for Samsung Gear Watch is not in their
system so that they cannot create a case to claim warranty. My serial number
is 11 characters which is shown in the box and the back side of the watch.
However, Samsung support says it is invalid.
Also, I cannot register my Samsung Gear Smartwatch at Samsung website.
Have anyone here claim warranty for your Samsung Gear Watch before ?
Thanks.

Warranty claim topic

Hello!

If I need to send my M8 in to have a hardware issue fixed (loose audio jack) do I need to fully go back to stock firmware/ROM and s-on? If so, will it be difficult to get s-off again?

Thank you!
