@ Peter B -
6/7 about 85%, not good for me, we will take a look later
@ Dat:
Well. Actually it is 8 / 12 
Anyway. It is Ok for me if those 66% work reliably 8)
G120 seems more sd card friendly. But then you have to admit, that the firmware had more time to ripe. So I am looking forward to the next releases.
Thanks for looking at it.
I think I located the problem and found an solution (again).
Two of the pins of Socket 10 on the G400HDR were not soldered to the board. So sometimes there was a connection sometimes there was not. I didn’t see it at first, since there was not much solder on the other pins as well.
@ Peter B -
Thank you for letting us know about the issue. We will be rechecking the ones in stock.
