Hi !
Glad to learn I'm not alone on the planet with this problem, although this topic is hard to spot on the web !
I own a JVC KD-X330BT, tried to upgrade it but same thing happened, got stuck on NO FILE on the dial.
Nothing works ! I did a reset, unplugged power plug in the back, but it still stuck.
One question please: why has the unit to stay unplugged for 5 days ? Did you try any shorter delay ?
Thanks a lot
Stephan
