I have this same error. Black screen with red letters "NO Xecuter3 Chip Detected!" pops up right after the x3/xbox logo. Soldering looks good. I have the samsung SD-616T flashed to SD-605B. This drive worked very well with halo 2 before the chip came in the mail.
I have a 1.0 xbox with the pin header installation. This is my first xbox mod, so I have no idea what I'm supposed to be seeing, but I don't think this is the right message

The LCD screen either is blank or all the characters are black.
Also, the ftp server doesn't work. I can't connect to it at any time using ftp. I can flash via the web server very easily. Smart ftp says: (btw, 192.168.0.14 is the dhcp assinged addy)
