jtagging is last resort m8 i wouldnt go down that road yet.
simply download a few versions of dreamup (earlier versions seem to work better for problem boxes ) use network aswell if ur able to as its ALOT faster to flash any image

and re-try to flash dk image bud keep trying it will sort it. also i find DCC crap

far too many things to go wrong (similer flashwizzard pro is the same ) alot of times peeps over compilcate the dreambox and software
Dreamup
smartftp (or filezilla ftp program)
and windos telnet (or maybe putty if u wish )
these are pretty much the ONLY software any dreambox owner should use problems can arrise with these "all in on wonders " pmsl
again prob waisting your time with erase.img as dreamup does infact erase your flash chip twice during flashing
jtag is ONLY for when its a complete no booter ie no lights on at all and no output from hyperterminal!!
dont give up on it ull get it bud
cheers
