Yesterday, after testing the Neutrino Image, I tried to upload Gemini with Flashwizard Pro... which stopped responding after a while....
result: My Dreambox turned into a zombie....
This morning I've built a null modem cable, and managed to access it with DreamUp... pfffff....

I used the last version. Ethernet upgrade, didn't even start.... Serial upgrade also failed at about 85%...
So I tested an older version, and managed to upload neutrino...
To anyone who migth need it, here's the wiring for the cable:

6 --- 4
