Hi there,
I've the same problem on my Advantage.
I made it to the 'hard-reset-screen', but in here it tells me: 'Press ACTION to restore factory default'.
Now, I assume that 'ACTION' means, press down joystick.
However, my device doesn't have an joystick.
I'm not even sure, that it's really an advantage, as I got it handed over as an Athena anyways.
I'd highly appreciate it, if somebody could tell me, which device this is from the photo I attached and maybe also give me 'hard-reset-instructions' for whichever device this is.
Kind Regards
Andreas
