No... still the same thing happening. Flashed the fiasco image without the -R tag this time, was succesful. Then when I came in to type

flasher-3.5.exe -F RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin -f -R

it founds my device RX-51, then
"Booting device into flash mode.
Suitable USB device not found, waiting"

When it says its booting device into flash mode, my N900 actually restarts, ignored my finger pressed on U, and goes on to attempt to boot normally, but get stuck at the loading bar...while the command prompt stays there waiting for a suitable usb device... help?
