for my DM800HD, i still not solve it yet although i strictly follow the steps given.. i don't know why.. it is still "connection prepared. now switch on your dreambox". If i switch off my dreambox, i will lost the COM2 or any COM that is plan to be use for flashing. I use the Null Modem Cable that connected to USB to Serial Adapter to my notebook. However, without the adapter, it did not detect or use any COM. If I use null modem cable DB9 female to USB (notebook), then it detected as "Unknown USB device" and asking for driver which cannot be found anywhere in the forum or websites.

Any better solutions for "CA NOT FOUND" problem?

Please help...
