I tried to reflash my N800 to the latest OS2008
- Downloaded the latest OS2008 5.2008.43-7
- ran sudo ./flasher-3.0 -F RX-34_DIABLO_5.2008.43-7_PR_COMBINED_MR0_ARM.bin -f -R
- Press <HOME> and <PowerOn> button
- Message on PC shows "Suitable USB device not found, waiting".
- N800 shows Nokia logo with USB symbol
- Nothing happens

I'm sure I've followed all the instructions. I have upgraded once before from OS2007 to OS2008 without any problems.
My N800 was working before. Now it won't boot. It just shows the Nokia logo and turns off after 1 minute.

Can anyone help me on this?
