There is nothing to be dissatified with the resolution of the problem presented when searching for this issue.

but I am still having problems.

1. It is wirelessly connected to the gear and is looking at the log.

2. made with Samsung certificate.

3. When I created the certificate, duid also displayed and registered properly

4. The ‘Permit to install applications’ is not required for this device.

I would like to try installation only.

My project name is PleaseInstall 🙁

What more should I do?
