To get fastboot to work I had to download this file:

from this thread:

and used this video:

to setup the "fastboot driver"
How to do the Driver setup:
Download the above file and unzip it this folder contains the driver needed to get past the initial plug-in of the DS7 to the PC while the DS7 is in "Fastboot Mode" select the folder of the DLed above driver and it will fail but now you leave the DS7 plugged in and go into your device manager and do as the above video shows...
now the DS7 will show as something useful...
now you will go to a dos promt by typing CMD in the run bar and following the steps on page 11 of this thread and running the command line there in post #103 it will then finish that... you will need a staple to turn off the unit in the sd card area on the left small hole...
then you will proceed with the right update.pkg file on the root of the sim card boot the unit using the + and power and select the update from sim and it works
