By the model number (Latitude E5470) I will say that the code ends with -6FF1, ex.: xxxxxxx-6FF1. This generator has been released, that's why you will find many sellers on eBay and very low pricing, these passwords used to sell for $40 to $55 USD or BestOffer over a year ago.
So just post a picture of password screen showing ServiceTag + suffix, someone will post the corresponding master password.

Dell without ServiceTag (equals) = Dell with NoPassword, or at least that's the way it used to be. There is a dell Asset utility that would clear the computer ServiceTag and hence the system password (and Computrace too), unfortunately utility stopped working on newer models.
