Thing of getting a Advance box questions

Hello I am looking at trying to get where I work one of these boxes. I will be using them to flash and unlock Nokia phones. Most the more basic ones like 101 Rm769 and 106 rm-962. As well as the news Lumia phones.

I have a number of the above phones that have DEMO software load on the so I need to flash them to a normal UK working phone and then unlock them. Some of them are dual sim as well.

Can Advance box do this?
