Thanks again. I managed to find that option after but VPC still did not recognise my n900.

So, I got myself a livecd ubuntu and booted that way, installed the flasher deb and just flashed my n900. "CMT Flashed Successfully'.

However, nothing is displayed on the device screen. I fear it may be a problem with the screen.. might be time to open the device and check that the ribbon is connected properly, but I think that will invalidate my warranty.
