I've tried the instructions for flashing from linux, but my problem seems to be that I can no longer get the unit to go into 'usb mode'. The icon never appears in the top right corner and in fact it just has problems turning on. It will turn on sometimes and then cycle through the Nokia screen and go off, but it sometimes won't even turn on. I haven't found a pattern yet, but it appears that if I leave it for a little while and then try to turn it on it comes on and reboots.

Any more ideas?

And yes I'm holding down the 'Home' key.

TIA
