Okay sorry to hijack this thread since my N900 is not completely bricked.

I need urgent help. My device has had all sorts of issues and I need to reflash it to see if they go away. However, I am travelling back to UK on Wednesday. So I only have a couple of days to try it out and see if it works otherwise have to return it before I fly out Wednesday.

I have tried to follow the instrunctions in the link below and installed the flasher.

I am running windows 7. I start my device with u pressed down and go into flash mode (the USB icon shows in the top right of the screen). I then start the flasher programme and enter the command:
flasher-3.5.exe -F RX-51_2009SE_1.2009.42-11_PR_COMBINED_MR0_ARM.bin -f -R

I press enter but then I get the message "suitable USB device not found, waiting."

I disconnect and reconnect but still nothing. What am I doing wrong? Please help.
