Just downloaded IFA3.1.1 via another forum, English version. I've not used IFA before, but it was straightforward to use with my dBox2. The steps I used were:

1. dBox2 turned off.
2. Connected null modem cable PC to dBox.
3. Connected crossover network cable PC to dBox2.
4. Launched IFA, clicked "Next" to get to main dialogue box.
5. Clicked "Search" to locate my 2x image.
6. Selected my only network card.
7. Choose "yes" to nullmodem cable question, Com1 (default I think).

8. When I clicked "Start" I got an error message saying that ports my PC's network card used were already in use by some Windows service, and that I should give the card a unique IP address.

Cancelled IFA, the in Windows Control panel double clicked "Network connections", then right clicked over the network connection, then left clicked on properties.

Then selected Internet Protocol TCP/IP, and clicked on Properties, then selected "Use IP address" and typed in 192.168.1.1 then clicked "OK" several times.

Then launched IFA again, setup as before, and clicked on "Start".

9. Then powered up the dBox2.

Bingo - this time flashing proceeding without a hitch.

Hope these points are useful. Perhaps the part about setting the card IP address was only down to someting else I'd done to my PC, but other than this flashing was no problem.

Best wishes
