I followed http://wiki.maemo.org/Overclocking#Flashing_using_PC, tried to reflash the pr 1.3 image to my bricked n900. however, flash had a message that says Suitable USB device not found, waiting, and after i plugged the n900 onto usb cable, nothing happened. it doesn't seem like my windows 7 (32bit) laptop was recognizing the n900 device, and I was using the machine to sync with the phone just a few hours ago! Any ideas? Thanks!
