Stuck trying to factory reset

[Malc1975]

Today for some reason I started getting continuous unfortunately Google play services has stopped error message
Over and over again
Tried a few methods and still kept getting message

In the end decided to factory reset via the settings menu
Got to the little green android saying erasing for nearly 3 hours
Tried powering off and going through recovery but as soon as I select recovery it loops back to the erasing screen and that's as far as I can get

Completely stock rom granted the memory is quite full with music and downloaded maps areas but it shouldn't take this long to reset

Any help would be appreciated as I use it for navigation for work mounted in my truck

Just to update I got the android on his back with a red exclamation mark now tried restarting and it's back to erasing screen again

Another update
Managed to get finally past the screen and select factory reset
When I select this it says formatting etc.
The. I get
E/failed to mount cache invalid argument
I can't get any further
