They are all leased, so unless you get it factory sealed and never activated - NO CHANCE.
If you get a early test unit or a unit that someone had installed and decided to reap the profit by selling and switching to something else - they are leased - D* won't let you activate, no if and or but.
Once the original user disconnects it from the account they have to send it back to D* at request. Even if D* didn't request it back, it cannot be activated on a different account.
Now, if Directv is refusing to activate a never before activated unit, then that is something totally unprecedented.
