Can't seem to get any further!
Is there any hope or is this now a brick?

Geoge, no panic!
Notice if after connecting the GPS appears a tenuous illuminated in screen. If yes, disconnect the GPS again pressing and holding the button on/off for several seconds to make sure that is not on stand by.
Turn on again and so that you see the tenue bottom lit, press and hold the upper left corner of the screen gps. Thus you go into pre-boot mode. Calm down,
