Folks, my own K1 was initially somewhat unreliable (restarts, freezes..) and eventually totally died, and Innovv kindly replaced it, FOC (I dealt with them directly...). However, after that, and with it then operating quite ok, I made the error of flashing it, when I noticed a newer SW version on Innovv's site.
The flash has bricked the thing... I have tried all the recovery methods both those listed by Innovv and a few I know, nothing works. the odd thing is that it appeared to flash-update correctly and I could check through all menus etc. and all was normal after the flash completed. Then I turned it off and that was that! Now, it won't respond in any way at all.. weird.
