Plutonium

The skins are not saved when I select in classes, (I already have everything unlocked by command) but even so they are not saved, I simply give it enter and it does not appear set. I appreciate your help.

Hello, I come from BO2, in this there is a system to unlock everything, without any progress before, just by giving a button everything is unlocked.
My question is in MW3 IW5 can the same be done? Or on the contrary, do you have to unlock it with the progress of the player?
