This is usually associated with the device being Prenormal. Does this show on the Download mode screen ?
However some newer Samsung have a Download mode screen with very little info.
First off the best bet is to have the device online (and with SIM installed, if a phone). Sometimes it is necessary for a new or refurbished phone to have made 5 minutes of calls, sometimes checking for updates will release RM Prenormal. RM is remote monitoring by Samsung, hence the reason to connect to their servers. Alternatively Prenormal is Knox derived.
