To generate a distributor.12 and author.p12 if you don’t have one already
download the Tizen SDK (this takes a while)
Open package manager and install the Tizen 4 and 5 wearable tools
Install the Wear extensions
Install the Samsung certificate extension
Either launch Tizen Studio and from that IDE launch Certificate Manager
or
from the app menu launch Tizen Studio → Certificate Manager
If you are on a preinstalled version of Windows 11 the device manager is missing an old 32 bit .dll and won’t launch but you can use GWS to connect to your watch and the certificate manager will fill in the DUID
Follow these instructions making sure you use Samsung certificates not Tizen certificates
I have a couple other things to try but I need to recuperate and try another day.
