If it works on new firmware, (which I doubt at this stage) Im not sure how to get the USB firmware loader working, I have a copy of dev_flash on my USB stick, I select the option in CFW Settings, I get the message "Level2 Kernal poked" but no other change, I do a soft reboot, no change. So Im not sure of the correct procedure. I expected an automatic reboot with the dev_usb mounted as dev_flash.
