Nur Im English ...entschuldigung
Yesterday evening I flashed (*eminin 28 image...Moderator of this board seems not like to this) trough null-modem cable. It did not started immediately but today morning I had Tera term terminal program connected to RS232 and when I started first time in morning it worked!!
I'm still inside my guaranteed period so I wonder what would been happened if I had sent it to my Dreambox dealer and through him to Dream Multimedia.
Interesting side effect of my ERROR UC0 case was that if I took HDD out it didn't gone to the point where ERROR UC0 comes to the LCD display. When HDD was removed there was only two square dots appearing on the left side of LCD.
