I have a Zebra ET45. I'm using SOTI Version: 15.2.3.1033. 

I've enrolled it with enterprise profile. For other devices it is working. But for ET45, profiles are not getting installed. 

Enrolled device I can see but I'm not able to figure out why Mangement Type is Unknown.

What could be wrong? Any idea?

It doesn't even say that profile installation failed etc.
