I was trying to fix a mate's sagem dbox as it was stuttering/freezing. I was flicking through all the different ucodes to see if it would resolve anything but the vortex one has screwed things up. The commando boot image loads up on the screen, then the little world icon twirls on the box's lcd and then the bloody thing just turns itself off. does anyone know how i might be able to fix this without getting a null modem cable? would the network boot so i might be able to restrict the os from getting access to that vortex ucode? i could replace it with a suitable one with the exact same file name. would that sort it out?
