Hi,
i'm experiencing a similar problem: tried to update the firmware of my HS-D300GL; but problems occured on my desktop and now, when powering the LS, the DIAG led immediately starts blinking 5 times (indicating firmware problem), repeatedly.
So like this, the device is not "running", so i guess no change of getting connected to it.
I also got it to power on, by pressing the reset button while powering on. Led are blinking indicating it should be in EM mode, however, i've read somewhere that this does not mean it's in EM mode.
Anyway, i am unable to access it via ping of FW updater, changing my ip address to one in the range of 192.168.11.x; cant connect directly however, as i don't have a cross over cable.
So what is now the best/easiest way to reflash my firmware. So be it if i lose the data on the device...
I already read some things about the knoppix bootable cd, but its unclear how to ruhn the fix_ext2_magic-1.1.i386.tgz then as its now on my desktop pc.
Thanks for your input
