BMW F series iDrive reboot reset issue FIXED without replacing entry nav

So over the past few years this problem has plagued a huge number of late model F-series BMW's running the Entry Nav system we have changed countless units after failed software actions....
Software action has been largely unsuccessful meaning the only option to resolve the issue was to replace the headunit. With costs upto £1600 fitted and programmed it was not an option for most customers.
So we dedicated some time to the problem and came up with a software action which has been successful on every unit we have tried so far.
This is only for the HU-Reset issue suffered by the Entry Nav unit and Basic version. This is usually identified by the system constantly rebooting before the Nav software can load.
