and according to the log which is saved on the USB-Device
all went fine so far but there is only port 8008 and 8009 open
so no telnet or something to go there

After the setup to my Wifi via the Android-App i got the message
to wait for update and continue when finished, since the dongle
wasn't connected to hdmi i just waited a bit and did so.
It appears to work proper and reports build 16664, maybe
this version need a newer exploit ?
