I also had this happen 3 or 4 times when I first bought the helix., same red 28 on screen and a boot up that just did not move beyond the first screen. it all happened over a period of a few days, switching it on-off then on-off again cured the problem. then after that it went back to normal, until I updated it to firmware 2, then it started crashing while I was mid way through playing, it only happened twice, I updated the firmware again and that cured the problem, that would have been really bad if it was at a gig.moving on to the present update 2.5 I have to turn it on- off and on-off again every time I use the helix now. updated firmware to 2.53 same problem still happening. I have opened up a ticket now, see where this takes me.
